This website, click on link above, is managed by volunteers in England, in particular Linda Elsegood, Trustee. All the videos are no doubt helpful, but I would point out particular interviews:

.

Rachel Allen, PhD – England – is a scientist with research background in the innate immune system, glia, cytokines. She discusses Toll-Like Receptors which is where naltrexone acts.

.

Jarred Younger, PhD – Stanford researcher  – has published studies using LDN on persons with fibromyalgia.  He discusses plans for testing it on other conditions possibly including depression and using it for children.

.

Pradeep Chopra, MD – Anesthesiologist in Rhode Island – uses LDN for CRPS. With Mark Cooper, MD, they have published on it, acknowledging my contribution in teaching him my experience using LDN for years in many persons with intractable pain.

Ketamine Inhaled – Bipolar Child NPR – Review of Ketamine for Depression

.

NPR reported yesterday on the beneficial effects of ketamine for depression, this time reporting on a ketamine inhaler prescribed by Demitri Papolos, MD.

.

Dr. Papolos is Associate Professor of Clinical Psychiatry at the Albert Einstein College of Medicine and Director of Research of the Juvenile Bipolar Research Foundation.

.

He “is one of a handful of psychiatrists in the world who began to see and to speak out about the possible deleterious effects of antidepressants and stimulants in the population of children within the bipolar spectrum.”

.

This NPR report described a syndrome Dr. Papolos has identified of Bipolar children & adolescents consumed by fear. They described a boy who had extreme attacks of rage for decades, and horrific violent nightmares.

.

The boy had attempted suicide at age 5. He was hospitalized in a psychiatric unit at age 12 and strapped down in a padded room, terrified. He failed many medications for years, some made him worse, and he was literally never able to complete a meal at table with the family without flying off in a rage or someone leaving.

.

in 2010, the boy tried Dr. “Papolos’ ketamine treatment. He says he’ll remember the day for the rest of his life. ‘I think we did two puffs, and I remember I sat up and I just started laughing,’ he says. Then his mother picks up the story: ‘You said you had an internal feeling of calm that you had never had before in your life. And when we came home that night, that was the first night that we ever all had dinner at the table without somebody leaving.’”

.

This boy, George McCann, now at age 22 is finally able to begin a more normal life. He needs the medication only every third day. “Papolos has treated about 60 young people with ketamine so far and says all but two have had dramatic responses.”

.

“The number of patients treated so far is small, and the approach is so new it hasn’t been tested by other researchers yet. Papolos says he’s hoping a study he published late last year will help persuade other researchers to try the drug on other children.”

.

“In the meantime, George McCann continues to inhale a prescribed dose of ketamine every third day. The fear and anger that once dominated his life are gone, he says, adding that his mind is free now to work….”

.

The relief with ketamine from the prison of mood disorders is deeply important. Severe mood disorders such as Major Depression and Bipolar Disorder can destroy the lives of patients and their loved ones. At worst, they can be lethal.

.

A review of published cases of intravenous ketamine for depression asks : “Ketamine for depression: where do we go from here?

.

I think the answer is we need to simplify the method of treatment using inhaled ketamine and begin to give their lives back to the patients we see. It is one of the safest medications I have ever prescribed. It does not cause weight gain or loss. It does not cause sexual dysfunction. And although it may increase sedation when used in combination with other sedating medications, at the low doses needed to treat mood disorders, I do not see ketamine interfere with other medication.

.

Ketamine can relieve depression from one second to the next. And this young man needs the medication every third day. Is that too much to ask to gain a life?

Ketamine Rapidly Relieves Depression by Restoring Brain Connections

.

.

This research is one of the most dramatic findings in the field of depression and mood disorders. It was published in Science by researchers from Yale and the National Institute of Mental Health, discussed by PBS here.

.

The speed with which ketamine can relieve major depression is deeply moving to witness. In my experience prescribing nasal ketamine it works almost 100% of the time. I have discussed ketamine and previous publications on it for Major Depression and PTSD. It is also effective for suicidal and bipolar depression patients.

.

Ronald S. Duman, PhD, the lead scientist, reviews his group’s research in this 2011 video:

.

Stress and depression leads to structural changes in the brain and these structural changes are reversible.

.

Depression affects 17% of the population, almost one in five of the population. Only one third of patients are effectively treated by existing antidepressants, even after many weeks. Nerve growth factors, in particular BDNF, are decreased by stress, with a very significant loss in depressed patients. BDNF produces antidepressant behavior in rodent models of depression.

.

BDNF is important for influencing the survival and function of neurons.

.

There are certain neurogenic zones in the brain that produce new neurons. Stress decreases the number of new neurons. Chronic antidepressant use increases the numbers and proliferation of these new neurons. Antidepressant treatment increases neurogenesis and this is dependent upon BDNF, this neurotrophic factor.

.

[His slide shows] Exercise, Prozac, ECT, antipsychotics, antidepressants increase neurogenesis.

.

Not only are there more synapses made by ketamine, but they are a larger size which is indicative of ones that are more functionally connected. Antidepressants take many weeks. A single dose of ketamine rapidly reverses depressive behaviors and loss of connections and completely reverses the decrements that had occurred over several weeks.

.

In suicidal patients given ketamine at Yale in the Emergency Room, within a matter of hours, the suicidality is completely reversed. These people are better for weeks after a single dose of ketamine treatment. [emphasis mine]

.

Therapeutically ketamine is even more rapidly acting than ECT.

.

Ketamine increases BDNF. But research shows its effects are blocked in mice that are deficient in BDNF. Riluzole also influences BDNF, but the side effect profile is so serious that I would not consider prescribing it without more data on safety.

.

Safety concerns are often raised in publications regarding chronic ketamine use. Most of my patients have no side effects at all. It is one of the safest medications we have and only a small percentage experience transient side effects. The favorable side effect profile, simplicity and low cost is key. The results for nasal ketamine are not 100%, neither is IV ketamine, but I have patients who respond to nasal spray when they failed IV ketamine. More importantly, they can carry it in their pocket and use as needed.

 

My experience prescribing ketamine goes back almost to the year 2000 for persons with chronic pain who have used ketamine several times daily, and since Spring 2012 for Major Depression. Its effect for depression lasts longer than for chronic intractable pain where it is short lasting. In the past, I prescribed it orally, by mouth, but since late 2011 I have prescribed it in a nasal spray and that form works for depression.

.

The neuroprotective action of ketamine has been published since at least 1988.

.

Patients can use nasal ketamine as needed. Schedules vary, everyone is different. It is short acting, but it does not stop working.

.

However, the use of other adjuvants, such as glial modulators, in treatment of depression is essential to understand, and is now work in progress. The role of inflammation and glia in the pathogenesis of depression has been well established since 2000, and discussed here.

.

Does ketamine also restore brain connections in patients with chronic pain? Chronic pain and major depression both lead to brain atrophy and memory loss. Both cause the same imbalance in glial cytokines. Both may respond to glial modulators, e.g. low dose naltrexone among others that have worked in some patients.

.

“The original link between ketamine and relief of depression was made at the Connecticut Mental Health Center in New Haven by John Krystal, chair of the department of psychiatry at Yale, and Dennis Charney, now dean of Mt. Sinai School of Medicine, who helped launch clinical trials of ketamine while at the National Institute of Mental Health,” reported by Yale  here.

.

I hope to add new approaches to treatment of anxiety that has failed to respond to other interventions.

Depression, Ketamine, Naltrexone, Glia and Inflammation – A Case Report

.

Current antidepressant therapies are only modestly effective, may have significant side effects and do not provide universal efficacy.

.

The role of inflammation and immune systems in the pathogenesis of depression has become well-established since 2000. Immune system activity is mediated by pro-inflammatory cytokines that change behavior.

.

This 2012 review is the first to summarize genetic variants of the inflammatory system involved in immune activation and Major Depressive Disorder, Major Recurrent Depression, Dysthymia, Childhood Onset Major Depression and Geriatric Depression: The role of immune genes in the association between depression and inflammation: A review of recent clinical studies. They reviewed 52 papers of which 27 are case-controlled studies. 

.

Pro- and anti-inflammatory cytokines are produced by glial cells in the central nervous system (CNS). Glial cells make up 90% of the cells in the CNS; 10% are nerve cells, neurons. When glia are activated, they produce cytokines that lead to inflammation. Glia and inflammatory cytokines play a role in infection, stroke, trauma, chronic pain, Multiple Sclerosis, Alzheimer’s Disease, Parkinson’s Disease, ALS and Major Depression. The Nobel Prize was awarded in 2011 for discoveries of the innate immune system, in particular the mammalian Toll-like receptor 4 (TLR-4) which is the receptor for naltrexone. That discovery incidentally was made by Bruce Beutler at Scripps Research Institute.

.

You can read more about glia and the inflammatory response posted January 2011: Pain and the Immune System – It’s Not Just About Neurons – Naltrexone. This is not specific to pain but also relates to some with major depression.

.

Ketamine is a major anti-inflammatory and glial modulator. Naltrexone is a glial modulator that I have prescribed for chronic pain in low dose for almost four years in patients who are not taking opioids, and in ultra low microgram dose for more than eight years in patients who are on opioids for pain. Some of those case reports are posted on this site.

.

Low dose naltrexone, LDN, may be effective for Autism, Multiple Sclerosis, and some autoimmune diseases. Jarred Younger at Stanford has shown fibromyalgia symptoms are improved by LDN; Jill Smith at Pennsylvania State University, Hershey, has shown remission in Crohn’s Disease with LDN; and Bruce Cree at UCSF has shown improved quality of life in a small study of Multiple Sclerosis that he is pursuing with larger multi-center studies.

.

Case Report

.

This week I saw a young man who traveled from Northern California for me to possibly treat major depression with nasal ketamine. Depression prevented him from working for the last two years. He scored 34 on the Hamilton Depression Rating Scale. Scores over 24 indicate severe depression. On June 4, 2012, we started his treatment using ketamine nasal spray. The daily dose was increased but has not yet reached an effective level. In my experience of prescribing ketamine for pain and depression in the last eleven years, the dose differs for everyone and is not related to age, gender or body weight.

.

As conveyed by him to me, his progress thus far:

.

ON JUNE 7, 2012, early morning, he used 40 mg of ketamine by nasal spray. He reported feeling dizzy, experiencing spinning sensation for two hours and then was his usual self, i.e. he felt bad the rest of the day as his usual self but vision was better. His strabismus (lazy eye) usually depends on better mood, but mood was unchanged.

.

At 3:00 pm, he took naltrexone, a very low dose approximately 4 mg.

.

ON JUNE 8th: approximately 12 hours later, he woke at 2 AM. He later told me that he was feeling “extremely sharp! I felt great! Clear in mind, quiet and calm. I didn’t realize how noisy my mind is till everything felt calm.” He returned back to sleep.

.

He woke again at 6 AM feeling great! Not thinking negative thoughts, but no other change, i.e. did not like or love activities or people anymore than in recent years with his depression.

.

At 1:15 PM, in the office his self-rated improvement of depression was 40% due to the low dose of naltrexone taken yesterday afternoon. He had no effect from ketamine as yet, and had not used any in more than 24 hours.

.

My plan has been to trial low dose naltrexone for persons with treatment resistant depression. If it is effective, then ketamine is not needed. Ketamine is a short acting medication and may pose issues such as tolerance, whereas low dose naltrexone is simple, once daily, used with few side effects and has never caused tolerance in my clinical experience.

.

It is very possible that with such rapid improvement overnight and continued treatment, his depression will continue to improve over coming weeks and months.

.

RSD, Complex Regional Pain Syndrome – a case report

.

Severe Pain for Three Years,

 80% better in 10 days

.

“This has been life altering.”

.

This is a very bright young woman who was an all state volleyball player until onset of Complex Regional Pain Syndrome three years ago in the right hand and wrist. It began after blood was drawn from the hand for a chemistry study and, one week later, the fingers turned black, lost blood flow, followed by emergency surgery for removal of a blood clot from the back of her hand. She woke after surgery, tearing the sheet off due to intense pain on light touch — that is called allodynia — and then developed severe edema from the hand to the shoulder.

.

It was four excruciating weeks before the diagnosis of complex regional pain syndrome was made.

~

CRPS or RSD is a diagnosis that every MD,

every surgeon, every ER doctor,

every psychiatrist and psychologist, every nurse and therapist should know how to diagnose.

.

Because she was a minor, they would not do nerve blocks.

.

She developed contractures of the fingers and hand,

was unable to move the fingers.

  A major university hospital diagnosed Munchausen Syndrome;

mom was diagnosed with Munchausen’s by proxy.

.

This happens so often. This is 2012.

If it’s not the doctors,

it’s the insurance companies

creating roadblocks to diagnosis or treatment or both.

.

Why is pain management not taught at medical schools?

Only 3% of schools today give 30 hours instruction in four years, Yale most recently.

.

.

At a major university hospital two hours away, she failed to respond to 14 stellate and brachial plexus blocks. But the wound reopened by itself, the stitch fell out. The psychiatry department evaluated her after she was so drugged with methadone, she does not even recall the interview. They diagnosed Munchausen Syndrome. That changed everything. Relationship went sour. Distrust of MD’s began and was confirmed many times in many places along the northeastern corridor and Texas.

.

That fall, she became a student at the university of her dreams. The diagnosis of CRPS was confirmed at their university medical center hospital where they wanted to continue the same blocks that had failed. Elsewhere, the chief of a renowned ivy league university pain service wanted to talk to her only about spinal cord stimulators, declined by the family.

.

In May 2010, she qualified for an NIH study of neurotropin double blind 6 weeks on, 6 weeks placebo. Failed.

.

She was seen by Dr. Schwartzman in Philadelphia October 2011, and sent from there to NYC to rule out neuroma dorsum right hand, negative.

.

On Lyrica, she gained 20 lbs, then back to 130 lbs baseline when off of Lyrica. Intolerance to Morphine – hives, Duragesic – total body itching. Ambien – hallucinations, Lunesta – hyper. Benadryl helped somewhat. Detoxing from Nucynta – lips were bright red.

.

Her weight dropped from 130 to 115. Many medications were trialed and failed. Marinol helps pain slightly and gives the best sleep in years, better appetite. It does cause anxiety, but she had not slept in three years, and it gives 4 to 6 hours of good sleep. She developed sharp bitemporal headaches. I advised headache is a side effect of Pristiq —- now thankfully discontinued and better.

.

Since August 2011, she has had CRPS pain in the right leg, worse walking, weight bearing.  There is discoloration of the dorsum hand usually, at times along proximal forearm, recently at right foot and leg. She had edema up to the shoulder measuring 30 cm. Nails growth faster at the right hand, possibly less hair growth right hand. Temperature usually cooler on the right hand, at times at night the hand and foot become hotter. No change in sweating noted.

The first year, she had almost total loss of function in the hand with pain and contractures —and forced herself to move the fingers with OT and PT, then home exercise. She still has days when the fingers remain flexed, but 98% of the time there is full movement as she continually tries to use the hand/fingers to write and type. Nose may become ice cold and tingly since CRPS spread to right side of face and right lower limb. At times tingling fingers. She struggles with memory when pain is severe and with lack of sleep.

 .

Pain ranges 7 to 10, average 8. Edema was significant for one year, now comes and goes. Allodynia is present hands and feet, now a different scale than before when she could not even be in the car.

However, with weight bearing and walking, pain of the right lower limb became most intense.  She will be 21 in July, but on a bad day was unable to leave her bedroom to walk downstairs as pain was too severe. She would communicate with family by loudly calling or texting. It was unthinkable to make plans for the next week due to severe pain. She has osteoporosis with atrophy of the right upper limb, and has had color changes and edema of the hand.

.

She lives in an eastern state inland, two hours away from the mid Atlantic seaboard and major medical center. She failed ketamine infusion at a major university medical center on the east coast. The cost and inconvenience was significant and the family did not know that ketamine may fail to have any effect if taking opioid analgesics. Once mom discovered that, she was able to wean off the opioid medication. Ultimately, after many more interventions, much later, in crisis, she did benefit from IV ketamine infusion, and was able to regain some movement of her fingers on the right hand, but there was no lasting relief. It was a struggle to obtain approval through her insurance.

.

She has been spending a great deal of time in bed for months. Morning stiffness is widespread for one to two hours. Bending is difficult, feels as if “hit by a bus,” but she does stretching, moving, distraction and Yoga when able.

.

Much better in 10 days

.

Day one: pain of the entire right side, face, trunk, limbs, rated 7 to 10 on a scale of 10, average 8. She guards the dominant right hand and the signature is difficult. Atrophy of the right upper limb is present, nails longer on the right hand, dusky dark erythema and long jagged scar over the dorsum right hand, mild erythema of the right upper and right lower limbs.

.

On the first day, in the office, she tried the first dose of ketamine nasal spray and after a repeat dose, she was puzzled, thinking to herself, then let us know she realized she was able to concentrate. A small dose is not enough to relieve severe pain, but even major depression can vanish at that dose. Two sprays relieved the brain fog of depression; pain was still 8 on a scale of 10. Blood pressure and pulse did not change before and after doses. She felt hopeful.

.

In the next few days she was able to do the unthinkable: make plans with friends, walk 45 minutes, become active, and remain active in a way that had not been possible. She was far more active with much less pain.  Over the weekend, six days after she arrived, after we had sequentially added several new medications, she found the dosage of nasal and sublingual ketamine that worked for her. She has actually had times when she was pain free. As noted during prior ketamine infusions, she requires a far higher dose than most patients to achieve effect. The plan now is to use higher doses at home when time permits for best effect, and booster sprays of nasal ketamine as needed when away from home. She can carry it in her pocket. There is no need for ICU infusions and the fight to get insurance coverage for those stays.

.

Of great significance, she has even made plans for the entire summer.

.

More details of her case will be added, as time permits. For now, this page is here to allow the patient and family and others to send comments. She will continue slow titration of other medications that will take three months before reaching the target dose, before we can assess efficacy. Based on my experience treating chronic intractable neuropathic pain including CRPS, it is possible these medications will be able to stabilize and relieve pain without ketamine.

.

See other case reports of treatment of CRPS here, here, and here.

.

You can read some of the science of pain, glia and inflammation. Ketamine is significantly anti-inflammatory. Three of her new medications are glial modulators. Treatment of severe chronic pain usually involves rational polypharmacy, not one medication and not medication alone. It requires a holistic approach to heal: P.T., O.T., massage, cognitive behavioral therapy, guided imagery, visualization, positive thinking, remaining active, and other modalities that depend upon the underlying cause: physical, emotional, spiritual, and financial. The treatment for CRPS is not specific for that condition alone, but the gains can be possible with tremendous discipline, effort, single minded determination and the loving support of friends and family.

.

Be cautious of spinal cord stimulators. Try everything else first.

They can create pain and scarring or tether the spinal cord.

Be proactive.

Remember that guidelines and strategies for diagnosis and treatment are outdated.

Patients and doctors do not understand that opioids create pain.

A 2006 publication from Vanderbilt shows how much better pain can be to taper off.

The abstract:

Significant pain reduction in chronic pain patients after detoxification from high-dose opioids.

Ketamine Intranasal for Rapid Relief of Pain and Depression

~

Poorly managed pain can evolve into chronic disease of the nervous system

~

Ketamine is an important analgesic, more important than opioids. It can dramatically reduce pain, and rapidly relieve depression and PTSD.  Please read my earlier posts here and here. And the NPR report here just after I posted this (skip to their last section). Yes, it is FDA approved and legal. One woman said:

.

 ’It was almost immediate, the sense of calmness and relaxation.

‘No more fogginess. No more heaviness. I feel like I’m a clean slate right now. I want to go home and see friends or, you know, go to the grocery store and cook the family dinner.’

.

NPR again reports ketamine’s rapid relief of depression. A 28 year old man whose refractory depression began at age 15, after ketamine, says:

.

‘I Wanted To Live Life’

.
Stephens himself has vivid memories of the day he got ketamine. It was a Monday morning and he woke up feeling really bad, he says. His mood was still dark when doctors put in an IV and delivered the drug.”Monday afternoon I felt like a completely different person,” he says. “I woke up Tuesday morning and I said, ‘Wow, there’s stuff I want to do today.’ And I woke up Wednesday morning and Thursday morning and I actually wanted to do things. I wanted to live life.”.
.
Since then, they treated him with Riluzole that is FDA approved for ALS and has one of the dirtiest side effect profiles I have ever seen in medicine with serious organ toxicity. Ketamine rarely causes mild transient side effects, usually none. It appears the concern is how ketamine is used on the street with potential for abuse. I do not see ketamine abuse in my patients, some of whom are on opioids for pain or Valium family medicines from their psychiatrist. All of those have a greater potential for abuse, also not occurring in my patients. Pain and/or depression can lead to suicide.
.
About 18 months ago, researchers at Yale found a possible explanation for ketamine’s effectiveness. It seems to affect the glutamate system in a way that causes brain cells to form new connections.
.
Researchers have long suspected that stress and depression weaken some connections among brain cells. Ketamine appears to reverse the process.

.

It would be of interest to see a case report of the bladder problems they mention. Is this in a single drug addict who used many unknown medications on the street? Several physicians have infused IV ketamine for persons with pain for many years, in far higher doses than I prescribe, with no report of any but transient minor symptoms.

.

David Barsook’s 2009 review, reference below, describes changes that cause memory loss and brain atrophy with chronic pain, in particular, Complex Regional Pain Syndrome (CRPS), and they also occur with chronic depression:

~

With the onset of chronic pain (including CRPS) a number of changes in brain function occur in the human brain including but not limited to: (1) central sensitization ; (2) functional plasticity in chronic pain and in CRPS; (3) gray matter volume loss in CRPS ; (4) chemical alterations; and (5) altered modulatory controls. Such changes are thought to be in part a result of excitatory amino acid release in chronic pain. Excitatory amino acids are present throughout the brain and are normally involved in neural transmission but may contribute to altered function with excessive release producing increased influx of calcium and potentially neural death.

.

Brain atrophy and memory loss has also been shown in chronic low back pain as well as in chronic depression.

~

Barriers to management of chronic pain are many:

~

Although opioids are effective for acute pain, effective treatment of chronic pain is often daunting, particularly neuropathic pain.

~

Opioids have been shown to create pain causing imbalance in the glial cytokines that favor pain rather than relief of pain. Opioids carry the risk of opioid-induced hyperalgesia which is a severe pain sensitivity. They affect the brain and endocrine system. Opioids may fail to offer significant relief, fail to improve function, and risk misuse, abuse, diversion and death. Their costs are astronomic, insurance coverage is increasingly limited, the potential for complications may be life threatening in a hectic medical setting, side effects can be lethal, lack of physician training in use of opioids and alternatives to pain control lead to increasing deaths, addiction and diversion. It has become a national emergency and a trillion dollar war on drugs.

~

Complications can be greatly reduced through use of a scrupulous history and physical examination, but reimbursement is directly proportional to the shortest time spent with a patient. Will that help assessment and care?

~

Individuals may have dramatically different responses to opioid therapy; some may not tolerate any, and relief must be balanced with side effects that increase as the dose increases. Patient status may change and require IV, rectal or tube delivery instead of oral formulas; drug-drug interactions may require rapid changes, and disease of kidney, liver or brain may require modifications or stopping altogether. They may increase risk of falls and cause central sleep apnea with drop in oxygen because the brain fails to give a signal to breathe.

~

Chronic pain can lead to loss of sleep, hopelessness, depression, anger and other mood disorders such as panic, anxiety, hypochondriasis and post traumatic stress disorder [PTSD]. Treatment of mood disorders are shown to profoundly reduce pain perception and/or ability to cope with pain.

~

Ketamine is anti-inflammatory and can reduce the need for opioid use, thus reducing the pain and side effects caused by opioids.

~

Nasal ketamine is more effective than oral ketamine for pain relief; oral dosing has no effect on depression.

~

Nasal delivery of ketamine is now possible due to advances in metered nasal sprayers that deliver a precise dose. No needle is required, no IV access, no travel to a specialist needed.

~

You can carry pain relief with you and use it as directed when it is needed.

~

Ketamine is an NMDA antagonist: it antagonizes the NMDA receptor which plays a profound role in pain systems and centralization of pain.

~

Ketamine is neuroprotective and it can help other disease states as noted by Barsook, 2009:

~

Besides improvement in pain, “there may be lessons from other diseases that affect the brain; it is noteworthy that acute ketamine doses seem to reverse depression and ketamine decreased prevalence of post-traumatic stress disorder (PTSD) in soldiers receiving ketamine during their surgery for treatment of their burns. In addition ketamine attenuates post-operative cognitive dysfunction following cardiac surgery that has been known to produce significant changes in cognition. [emphasis mine] The data suggest that the drug can alter or prevent other conditions based on its NMDAR activity where other drugs NMDA receptor antagonists are perhaps not as effective in these or pain conditions. Lastly, NMDA antagonists have been used in degenerative disease (and pain may be considered a degenerative disease as defined by loss of gray matter volume, see above) with mixed effects perhaps relating to how they act on specific NMDA subtypes. Taken together, ketamine may act not only on sensory systems affecting pain intensity, but also on a constellation of brain regions that are involved in the pain phentype. [sic, phenotype]“

~

Side Effects

~

Ketamine is more frequently used in babies and children than in adults because high doses of ketamine can induce hallucinations in the adult. Importantly, it is used in high dose in adults for treatment of Complex Regional Pain Syndrome.

Low doses, cause little or no side effects in adults. If present, they are transient and often resolve in 20 minutes. Patient who respond to ketamine report good acceptance as they find the relief of pain and/or depression far outweighs any short term minimal discomfort.

~

Pain care reform is urgently needed.

~

Research funding for pain is less than half of one percent of the NIH budget. More research is needed, but research on low dose ketamine for treatment of pain and depression has gone on for twenty years.

The public health crisis of untreated pain, which often results in disability, parallels the country’s struggle to halt the cost of health care. The longer a person remains with untreated pain, the less likely they are to return to work or to be employable.

~

Conclusion

~

Pain control requires urgent attention. It is past time to put into practice the use of this valuable medication so people can get on with life instead of being mired in chronic pain that for many risks suicide and ensures continuing decades of disability. Academic studies are usually limited by defining a predetermined dose rather than clinically titrating to effect. Thus no surprise, they find no effect as every patient will have no response until they reach their dose. And that dose, in my experience, falls into a bell shaped curve. One size does not fit all. Some respond at very low dose, others require much more, and the majority fall between.

In my experience prescribing ketamine for ten years, only a rare person has problems. Almost all find it has returned function or significantly relieved pain. Some have been able to entirely eliminate opioids that did nothing for their pain for decades, though they dutifully returned to the MD every month to chronicle that pain. Pain continued to be rated ten on a scale of ten; patient always compliant despite side effects of constipation and often depression. My patients find the benefits of nasal ketamine far outweigh the relief of oral ketamine and at much lower doses with fewer side effects.

~

Further, while the pain relief may be short lived, some find it gets better with repeat dosing, and relief of depression may last one to two weeks with a single dose.

~

Ketamine is a parenteral anesthetic agent that provides analgesic activity at sub-anesthetic doses. It is an N-methyl-D-aspartate (NMDA) receptor antagonist with opioid receptor activity. Controlled studies and case reports on ketamine demonstrate efficacy in neuropathic and nociceptive pain. Because ketamine is a phencyclidine analogue, it has some of the psychological adverse effects found with that hallucinogen, especially in adults. Therefore, ketamine is not routinely used as an anesthetic in adult patients. It is a frequently used veterinary anesthetic, and is used more frequently in children than in adults. The psychotomimetic effects have prompted the DEA to classify ketamine as a Schedule III Controlled Substance. A review of the literature documents the analgesic use of ketamine by anesthesiologists and pain specialists in patients who have been refractory to standard analgesic medication regimens. Most reports demonstrate no or mild psychotomimetic effects when ketamine is dosed at sub-anesthetic doses. Patients who respond to ketamine tend to demonstrate dramatic pain relief that obviates the desire to stop treatment due to psychotomimetic effects (including hallucinations and extracorporeal experiences). Ketamine is approved by the FDA for intravenous and intramuscular administration. Use of this drug by the oral, intranasal, transdermal, rectal, and subcutaneous routes has been reported with analgesic efficacy in treating nociceptive and neuropathic pain.

The intranasal route for ketamine administration has been applied only for pain of dressing changes in a single case study (Kulbe, 1998). In this patient, oxycodone and acetaminophen were ineffective to control pain during burn dressing changes in a 96-year-old woman cared for at home. She tolerated the burn dressing changes after three intranasal sprays of 0.1 ml each, in rapid succession, each containing 5 mg ketamine (15 mg total) (Kulbe, 1998).

~
Ketamine delivered intranasally was well tolerated. Statistically significant analgesia, superior to placebo, was observed with the highest dose tested, 50 mg, over a 3 h period. Rapid onset of analgesia was reported (<10 min), and meaningful pain relief was achieved within 15 min of the 50 mg dose. The majority of adverse events were mild/weak and transient. No untoward effects were observed on vital signs, pulse oximetry, and nasal examination. At the doses tested, no significant dissociative effects were evident using the Side Effects Rating Scale for Dissociative Anaesthetics.
The safety profile following treatment with ketamine was comparable to that seen with placebo.
Although patients did report side effects of fatigue, dizziness and feelings of unreality more often following treatment with ketamine than following treatment with placebo, no patient reported hallucinations and the side effects were generally reported to be of mild or moderate severity, and transient. No serious adverse events were reported and the incidences of associated adverse events were comparable for ketamine and placebo. Although study medication was administered intranasally, nasal signs and symptoms were few and inconsequential. A distinctive taste, however, was reported more often following treatment with ketamine than following treatment with placebo.In conclusion this randomized, placebo-controlled, double-blind study, in 20 patients, has demonstrated that intranasal ketamine is safe and effective for BTP [breakthrough pain]. Our findings augment an early but promising literature documenting the effectiveness of nasal administration of a variety of opioids for pain management in adults (Dale et al., 2002) .

This important paper covers essential points not mentioned by many, thus quoted at length below:

“Ketamine, brain function and therapeutic effect – neuroprotective or neurotoxic

With the onset of chronic pain (including CRPS) a number of changes in brain function occur in the human brain including but not limited to: (1) central sensitization ; (2) functional plasticity in chronic pain and in CRPS; (3) gray matter volume loss in CRPS ; (4) chemical alterations ; and (5) altered modulatory controls. Such changes are thought to be in part a result of excitatory amino acid release in chronic pain. Excitatory amino acids are present throughout the brain and are normally involved in neural transmission but may contribute to altered function with excessive release producing increased influx of calcium and potentially neural death. Here lies the conundrum the use of an agent that potentially deleteriously affect neurons that may already be compromised but may also have neuroprotective properties by mechanisms that include reducing phosphorylation of glutamate receptors resulting in decreased glutamatergic synaptic transmission and reduced potential excitotoxicity . Alternatively, ketamine may affect glia regulation of glutamate and inhibit glutamate release within glia. However, by whatever mechanism ketamine acts on CRPS pain, there does seem to be a dose/duration effect in that longer doses at levels tolerated by patients seem to prove more effective in terms of the duration of effects.

So what could be happening in the brain and what is required to alter brain systems and reverse the symptomatic state? Ketamine may diminish glutamate transmission and “resets” brain circuits, but it seems that a minimal dose and/or duration of treatment is required. Alternatively, ketamine may produce neurotoxicity and damage or produce a chemical lesion of affected neurons. These two issues are important to be understood in future trials. Reports from patients who have had anesthetic doses have included prolonged pain relief for many months. While the authors did not address issues such as the effect of dosing duration or repetitive dosing at say 6weeks, they did show a level of efficacy based on NNT that equals or betters most drug trials for this condition.”

….

“Conclusions

As a community we have a major opportunity to define the efficacy and use of a drug that may offer more to CRPS (and perhaps other) patients than is currently available. This is clearly an opportunity that needs urgent attention and a number of questions remain to be answered. For example, is ketamine more effective in early stage disease? How does ketamine provide long-term effects? Further controlled trials evaluating dose, duration, anesthetic vs. non-anesthetic dosing are needed. Few of us really understand what it is like to suffer from a chronic pain condition such as CRPS. Ketamine therapy may be a way forward that can be brought into our clinical practice through further controlled studies that will allow for appropriate standards for use in patients.”

Depression PTSD – Ketamine Rapid Relief

~
  • PTSD has a more direct link to suicide than previously thought, a current Texas A&M University study concludes – references below.

  • A high lifetime risk of suicide occurs in women who have been sexually and physically abused as young girls.

  • More than 300,000 veterans have been diagnosed with PTSD or major depression – many not yet diagnosed.

  • Risk of suicide is the highest during the first month of standard antidepressant therapy, and a significant number of patients do not have adequate improvement even after months, resulting in harm to personal and professional lives.

  • Patients are at suicide risk upon discharge from psychiatric hospitals.

  • Significant predictors of both suicide attempts and preoccupation with suicide are guilt and anger and impulsive behaviors.

    ~
    ~

  • Ketamine is the most important breakthrough in treatment of major depression with rapid and lasting effects.

  • Ketmine can help immediately, unlike all other antidepressants that may require weeks or months to work, if they help at all. See NPR report here - that appeared soon after I posted this (skip to their last section). It is FDA approved and legal. NPR again reports ketamine’s rapid relief of depression. A 28 year old man whose refractory depression began at age 15, after ketamine, says:

    .

    ‘I Wanted To Live Life’

    .
    Stephens himself has vivid memories of the day he got ketamine. It was a Monday morning and he woke up feeling really bad, he says. His mood was still dark when doctors put in an IV and delivered the drug.”Monday afternoon I felt like a completely different person,” he says. “I woke up Tuesday morning and I said, ‘Wow, there’s stuff I want to do today.’ And I woke up Wednesday morning and Thursday morning and I actually wanted to do things. I wanted to live life.”.
    .
    Since then, they treated him with Riluzole that is FDA approved for ALS and has one of the dirtiest side effect profiles I have ever seen in medicine with serious organ toxicity. Ketamine rarely causes mild transient side effects, usually none. It appears the concern is how ketamine is used on the street with potential for abuse. I do not see ketamine abuse in my patients, some of whom are on opioids for pain or Valium family medicines from their psychiatrist. All of those have a greater potential for abuse, also not occurring in my patients. Pain and/or depression can lead to suicide.
    .
    About 18 months ago, researchers at Yale found a possible explanation for ketamine’s effectiveness. It seems to affect the glutamate system in a way that causes brain cells to form new connections.
    .
    Researchers have long suspected that stress and depression weaken some connections among brain cells. Ketamine appears to reverse the process.

    .

    It would be of interest to see a case report of the bladder problems they mention. Is this in a single drug addict who used many unknown medications on the street? Several physicians have infused IV ketamine for persons with pain for many years, in far higher doses than I prescribe, with no report of any but transient minor symptoms.

    .

    Memory loss and brain atrophy occur with chronic depression, reported by the National Institute of Mental Health ~2001. The mechanism is described by Barsook referenced here.

    ~

  • You do not need to be hospitalized.

  • A single low dose ketamine treatment, given nasally, may reduce core symptoms of PTSD and depression. It can save your life.

  • Relief of depression may occur in 2 minutes to 2 hours and may last 1 to 2 weeks.

  • National Institute of Mental Health published 100% relief in a group with depression refractory to all treatment that failed as long as 43 years.

  • You cannot anticipate when suicidal thoughts occur, but you can carry ketamine with you for instant relief.

  • Ketamine is not toxic, not expensive, side effects if any are transient – usually none. It is compounded by pharmacy.

    ~

  • I can help. I’ve prescribed this medication for 11 years, spoken with some of the world’s foremost psychiatrists. Some of my patients with profound pain/depression travel to Germany for high dose ketamine coma treatment of RSD/CRPS and tolerate those doses. Ketamine is safe even in babies and children. Very few MD’s prescribe ketamine, and even fewer have much experience with it.

    ~

  • I need to examine you in person.

  • I can meet with you at my office and it is essential that you meet with my colleagues, a psychologist and psychiatrist.

  • Time is of the essence because we may need to adjust the concentration of ketamine. We need to determine your comfort level with its use.

  •  This must be a team approach.

  •  Please ask your psychiatrist to call me with your diagnoses and speak with me in person.

  • If you live long distance, this team should include your local psychiatrist, or one nearby, who will prescribe ketamine for depression.

  • Alternately, I will need to see you in my office every few months to renew the medication.

    ~

  • The medical literature on ketamine use is profoundly important. There are over 6,800 medical publications. Ketamine has potent healing powers. Karl Jansen, psychiatrist in London, believes that “ketamine has potent healing powers when used as an adjunct to psychotherapy.” There is nothing like it; however, treatment for serious depression still requires team support, not medication only.

  •  The World Health Organization reports that disability to due depression is second only to heart disease.

  • Suicide is a catastrophic medical emergency. I cannot stress this enough. Depression is treatable.

  • Your death is unnecessary. It would be a terrible loss to all who love you.

    Suicide Clinical Presentation

http://www.ptsd.va.gov/professional/pages/ptsd-suicide.asp The Relationship Between PTSD and Suicide  

PTSD alone out of six anxiety diagnoses was significantly associated with suicidal ideation or attempts. Anger and impulsivity have also been shown to predict suicide risk in those with PTSD.

Articles, below, support use of ketamine for rapid relief of depression, even for resistant bipolar depression. The lead author of the first three studies is Carlos Zarate, M.D., Chief of the Mood and Anxiety Disorders Research Unit of the National Institute of Mental Health, NIMH:

http://www.ncbi.nlm.nih.gov/pubmed/20673547   Rapid resolution of suicidal ideation after a single infusion of an N-methyl-D-aspartate antagonist in patients with treatment-resistant major depressive disorder

100% response in persons with refractory depression: 29% went into remission, another 71% were responders.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726824/figure/F1/  Ketamine and the next generation of antidepressants with a rapid onset of action

Potential targets for ketamine and similar agents induce rapid and sustained antidepressant effects. A diagram scientists and physicians will find useful for mechanisms. “Notably, ketamine’s rapid antidepressant effects have been shown to be modulated by AMPA relative to NMDA throughput. Excessive glutamate also stimulates the extrasynaptic NMDA receptors, which antagonizes the activation of neurotrophic cascades. The potential sustained (sub-acute) antidepressant effects of ketamine are hypothesized to be mediated by increases in CREB and BDNF expression, as well as the anti-apoptotic protein Bcl-2.”

https://www.sciencemag.org/content/329/5994/959.abstract mTOR-Dependent Synapse Formation Underlies the Rapid Antidepressant Effects of NMDA Antagonists

“The rapid antidepressant response after ketamine administration in treatment-resistant depressed patients suggests a possible new approach for treating mood disorders compared to the weeks or months required for standard medications….Our results demonstrate that these effects of ketamine are opposite to the synaptic deficits that result from exposure to stress and could contribute to the fast antidepressant actions of ketamine.”

http://psychiatry.jwatch.org/cgi/content/full/2010/1008/5 Ketamine’s quick antidepressant actions

“The resulting protein synthesis and neuronal alterations in the medial prefrontal cortex are the opposite of those produced by chronic stress….”

Carry On —> Inspiration

keep-calm-and-carry-on

This is a Cinderella story that will melt the most cynical heart.

Susan Boyle, the British singer, is an instant sensation!

Over 85.2 million viewers have seen her on YouTube in just one week – a record -

to watch her sing “I Dreamed A Dream from Les Miserables.

Born with brain damage, she was taunted all her life because she is slow.

Asked how she had the confidence to sing in front of a large audience, she says:

” I just had the ability to keep going.  You have to keep going.”

~~~~~~~~~

…..a beautiful, inspiring video

of Nick Vujicic, born with no limbs, speaks to students

whose tears run down their cheeks, whose love pours out to him.

Nick has found the purpose of his life and has become strong

through the agony of learning how to overcome what had defeated him from birth.

The miracle we are looking for is inside each of us.·
