What this blog is for:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Biking1 stroke rehab - 2013
I've changed dozens of tires so I know exactly what to do. None of this patching for me I just go straight to a new inner tube. Since this is my first tire change post stroke I found out that tire levers can also be used to snap the tire back onto the rim. That was the easy part. I spent the next 15 minutes wrestling the tire onto the front fork. With two useable hands I could have gotten it done in 10 seconds. But success was going to occur. That effort knocked the front brake pad out of alignment so the left pad was preventing the wheel from turning. And since this was the new SlidePad system it took me another 15 minutes to get it adjusted. Finally got it outside in the 58 degree weather and while I only rode around in the parking lot, it felt great. The seat was no longer twisting underneath me, the left foot was prevented from sliding off due to the toe clip. The new braking system allowed me to get going fast enough so I was no longer wobbling. The rear view mirror meant I didn't need to try looking over my shoulder. The only problem to be corrected is my left wrist curls and will not stay straight. But its happening and I am happy, happy, happy.
Ill. Fire Dept. Medics Sued For Misdiagnosed Stroke
http://www.firehouse.com/news/10912331/ill-fire-dept-medics-sued-for-misdiagnosed-stroke
Susan Miller's lawsuit, filed in Kane County this week, argues that paramedics only treated her for six minutes and failed to provide proper care after arriving at her house at 2:04 a.m. May 28, 2012, after she complained of numbness in her arm and that she had fallen and could not get up.
Miller told the paramedics she had drank alcohol earlier in the day and the paramedics, instead of treating her and performing other tests, told her son to have his mother "sleep it off," according to the lawsuit.
Less than three hours later, the woman's ex-husband took her to the Provena Mercy Medical Center in Aurora and doctors determined she suffered a stroke.
"As a result in the delay in receiving the proper medical treatment for her stroke, Miller suffered and continues to suffer from various injuries including but not limited to permanent facial paralysis, vision loss and one-sided paralysis," read part of the lawsuit. "The defendant's utter indifferent or conscious disregard for the safety of Miller is evident from defendant's failure to discover a danger through recklessness or carelessness and which could have been discovered with the exercise of ordinary care."
A message left at the Aurora Fire Department's main station was not returned.
Aurora city spokesman Clay Muhammad said the city had not yet been served with the lawsuit and would not comment. Miller's attorney, Dennis Stefanowicz, did not return messages.
Both sides are due in court June 13. Miller seeks a jury trial and unspecified damages, according to the lawsuit.
Walking in the dark
After Michigan state lost I went for a walk in the woods, this time with a headband flashlight. It took me 15 minutes to get it on one-handed. Great therapy because your foot placement is unknown so your ankle muscles need to immediately compensate for any deviations in flatness. I'll have to go sometime in daylight with my pruning saw to get the hanging branches trimmed. Then I walked around the apartment pond and listened to the mallards swimming and splashing around while watching the moon rise. Its great to be alive.

ABSTRACT
Watching object related movements modulates mirror-like activity in parietal brain regions
http://www.clinph-journal.com/article/S1388-2457%2813%2900120-X/abstract
Highlights
Abstract
Objective
We studied the activation of cortical motor and parietal areas during the observation of object related grasping movements. By manipulating the type of an object (realistic versus abstract) and the type of grasping (correct versus incorrect), we addressed the question how observing such object related movements influences cortical rhythmicity, especially the mu-rhythm, in the context of an “extended” human mirror neuron system (MNS).Methods
Multichannel electroencephalogram (EEG) was recorded during the observation of different object-related grasping actions in twenty healthy subjects. Different movies were presented, showing sequences of correct or incorrect hand grasping actions related to an abstract or realistic (daily life) object.Results
Event-related de/synchronization (ERD/ERS) analyses revealed a larger ERD in the upper alpha (10–12Hz), beta (16–20Hz) and gamma (36–40Hz) frequency bands over parietal brain regions depending on the type of grasping. The type of object only influenced ERD patterns in the gamma band range (36–40Hz) at parietal sites suggesting a strong relation of gamma band activity and cortical object representation. Abstract and realistic objects produced lower beta band synchronization at central sites only, whereas depending on the type of grasping an ERS in the upper alpha band (10–12Hz) was observed.Conclusion
Depending on the type of the grasped object and the type of grasping stronger parietal cortical activation occurred during movement observation.Significance
Discussing the results in terms of an “extended” human mirror neuron system (MNS), it could be concluded that beside sensorimotor areas a stronger involvement of parietal brain regions was found depending on the type of object and grasping movement observed.Acute Microvascular Changes after Subarachnoid Hemorrhage and Transient Global Cerebral Ischemia
http://scholar.google.com/scholar_url?hl=en&q=http://downloads.hindawi.com/journals/srt/2013/425281.pdf&sa=X&scisig=AAGBfm0CNg2J04M7tLmWYuYh11Fbfm-72w&oi=scholaralrt
1. Introduction
Subarachnoid hemorrhage (SAH) is a type of hemorrhagic
stroke, most commonly caused by a ruptured intracranial
aneurysm. At the time of aneurysm rupture, blood pours
into the subarachnoid space, and the intracranial pressure
(ICP) inside the rigid calvarium increases sharply, causing
a corresponding decrease in cerebral blood flow (CBF). The
patient’s clinical presentation on arrival to the hospital can
depend on the degree and duration of this initial global
cerebral ischemia.
Patients with aneurysmal SAHmay develop angiographic
vasospasm and delayed cerebral ischemia (DCI) with onset
3–12 days after the initial rupture [1]. DCI may or may
not be accompanied by large artery vasospasm as seen with
vascular imaging [2]. A multicenter randomized clinical trial
has not shown improvement in neurologic outcome despite
ameliorating the delayed large artery vasospasm [3].Whether
this is due to efficacy of rescue therapy in the placebo
groups or drug toxicity abrogating beneficial effects in the
clazosentan groups has not been resolved. Nevertheless, as
a result of these results, research in SAH has also investigated
early brain injury and acute microvascular changes
[4]. Nimodipine, an L-type calcium channel antagonist, is
the only pharmacologic agent that has been shown to consistently
improve neurologic outcomes in clinical trials of
patients with SAH [5].
Similarly, cardiac arrest (CA) results in global cerebral
ischemia that is transient in clinically relevant cases, since
if cardiac function is not restored, the situation is of pathological
interest only. Other causes of transient global cerebral
ischemia (tGCI) include asphyxia, shock, and complex
cardiac surgery [6]. The clinical presentation depends on the
duration of cardiac arrest and time to initiating cardiopulmonary
resuscitation. After global cerebral ischemia from
SAH or tGCI, a cascade of molecular events occurs, resulting
in variable degrees of brain injury and cerebrovascular
changes.
Global cerebral ischemia in postcardiac arrest has also
been studied extensively for many decades in various animal
models. Other than early induced mild hypothermia [7, 8],
clinical translation of neuroprotective strategies and therapeutics
has largely been unsuccessful.
The study of the microcirculation after tGCI and SAH
remains a difficult undertaking, but this strategy of study
may reveal potential therapeutic targets and new insights
into disease pathophysiology.The purpose of this paper is to
look at relevant animal and preclinical studies investigating
2 Stroke Research and Treatment
acute microvascular changes (within the first 48 hours)
occurring after either SAH or tGCI. Cerebral microvessels
may be defined as vessels less than or equal to 100 micrometers
in diameter [9]. Animal studies of focal ischemia or
studies focused on the large cerebral vessels (i.e., circle of
Willis arteries, basilar artery, etc.) are not included in this
paper. While we acknowledge that tGCI may occur in a
large heterogeneous group of disorders (i.e., traumatic brain
injury, intracerebral hemorrhage, etc.), we have chosen to
focus solely on tGCI secondary to cardiac arrest or mechanisms
mimicking cardiac arrest, such as extracranial arterial
occlusion. After providing an overview of various animal
models and general trends in cerebral hemodynamics after
SAH and tGCI, we provide an in-depth review of studies
investigating specific microvascular changes that occur in
these two conditions: (1) microvascular constriction; (2)
increased leukocyte-endothelial cell interactions; (3) blood
brain barrier (BBB) breakdown; and (4) platelet aggregation
and microthrombosis.

Why I survived my stroke
My brain reserve was built up.
by
1. bilingualism
2. new musical instruments,
piano, My daughter taught me 3 years prior but I never got beyond one-handed playing
saxophone, 3 years prior I started this but never got good enough to remember the finger positions after stroke. Its one of my goals now.
3. sudoku, I would do this every night before going to bed, worked my way up to doing the hardest ones in each book. Immediately post-stroke I tried this and couldn't juggle that many numbers in my mind, even the easy ones were off limits.
4. new outdoor activity, 10 years of whitewater canoeing. Providing both a cognitive challenge and exercise created neurogenesis.
My physical condition was great. Three years after the event during a physical my resting heart rate was 54 at age 53. The doctor asked what cardio exercises I was doing. 'None for the last three years'.
I received tPA within 90 minutes of onset of the stroke.
I wrote about this earlier here but this is a little more fleshed out. Video of Denison Falls there.

or neuropathic pain
or prevention as better than statins.
Whatever, tell them you need the ability to use it for whatever scientific proof comes along rather than limit it to current knowledge.

Draft rules for medical use of marijuana in Massachusetts, issued Friday by the state Department of Public Health, largely leave it up to doctors to decide which patients will qualify for treatment with the drug.
Patients must have a debilitating condition -- defined as causing weakness, wasting syndrome, intractable pain or nausea, or impairing strength or ability and limiting major life activities -- and the regulations list qualifying conditions, including cancer, glaucoma, HIV/AIDS, hepatitis C, and ALS(you need to get stroke in here at least). But the rules also would allow doctors and their patients to decide what other conditions would qualify patients for treatment. Poorly written - nothing on preventing disability or use for rehabilitation.
Pay it forward, you must respond for future survivors. Get off your ass and do something.

Mitchell, SD chiropractor denies causing Gunkel's stroke
http://www.mitchellrepublic.com/event/article/id/77150/group/homepage/
A local chiropractor has denied accusations from a local woman who claims a neck adjustment caused her to suffer a stroke.
In a two-page answer filed Monday, Gary Hendrix, a chiropractor with an office located at 310 N. Lawler St. in Mitchell, denies that a neck adjustment he performed on Christie Gunkel caused her to have a stroke.
Gunkel, who recently became treasurer of Davison County, filed a lawsuit in January claiming a neck adjustment she received from Hendrix on Aug. 8 caused a “dissection,” or tear, in an artery in her neck, resulting in a stroke. Hendrix admits to treating Gunkel, and admits she “had problems following treatment,” but denies he did anything to cause the stroke, court documents say.
Gunkel also claims Hendrix breached the standard of care and failed to inform Gunkel of all the risks involved in a neck adjustment, a claim that Hendrix denies in his response.
Gunkel is represented by Renee H. Christensen, of Sioux Falls. Hendrix is represented by J. Crisman Palmer, of Rapid City.
In an interview with The Daily Republic in January, Gunkel said she went to Hendrix’s office Aug. 8 because of soreness in her neck, and Hendrix treated her with a neck adjustment.
Later that day, Gunkel went to the emergency room at Avera Queen of Peace Hospital in Mitchell, where she suffered a stroke, she said. From there, Gunkel was taken by ambulance to Avera McKennan Hospital in Sioux Falls, where she spent four days undergoing CT scans and MRIs, as well as physical and occupational therapy.
Gunkel claims she suffered permanent injury, experienced and will continue to experience “great pain, discomfort, mental anguish and loss of enjoyment of life,” and has “been unable to perform several normal functions of life,” her complaint says.
Stroke’s Quantum Jump: The Interprofessional Team
http://deptmed.queensu.ca/blog/?p=220
My reply in the comments section, no response.
When are we going to get to the next quantum jump and start identifying interventions that are neuroprotective or stop the neuronal cascade of death? I know Dr. Michael Tymianski has noted that 1000+ drugs that worked in preventing damage in rodents did not work in humans. That might be explained by rodent inflammation is not the same as human inflammation. For my next stroke I will demand my doctor give me ibuprofen, levodopa, anti-depressants,minocycline, fish oil, amantadine or tell me why not.
More Dietary Fiber Might Help Thwart Stroke

For every 7-gram bump in daily fiber consumption, an individual's risk for experiencing an initial stroke appears to plummet 7 percent, the investigators concluded after analyzing 20-plus years of research.
More research would be needed to come up with an ideal stroke-prevention grocery list.

Researchers form new nerve cells – directly in the brain
You can use this to watch the cells to see how they are doing.
http://www.alphagalileo.org/ViewItem.aspx?ItemId=129731&CultureCode=en
The field of cell therapy, which aims to form new cells in the body in order to cure disease, has taken another important step in the development towards new treatments. A new report from researchers at Lund University in Sweden shows that it is possible to re-programme other cells to become nerve cells, directly in the brain.
Two years ago, researchers in Lund were the first in the world to re-programme human skin cells, known as fibroblasts, to dopamine-producing nerve cells – without taking a detour via the stem cell stage. The research group has now gone a step further and shown that it is possible to re-programme both skin cells and support cells directly to nerve cells, in place in the brain.
“The findings are the first important evidence that it is possible to re-programme other cells to become nerve cells inside the brain”, said Malin Parmar, research group leader and Reader in Neurobiology.
The researchers used genes designed to be activated or de-activated using a drug. The genes were inserted into two types of human cells: fibroblasts and glia cells – support cells that are naturally present in the brain. Once the researchers had transplanted the cells into the brains of rats, the genes were activated using a drug in the animals’ drinking water. The cells then began their transformation into nerve cells.
In a separate experiment on mice, where similar genes were injected into the mice’s brains, the research group also succeeded in re-programming the mice’s own glia cells to become nerve cells.
“The research findings have the potential to open the way for alternatives to cell transplants in the future, which would remove previous obstacles to research, such as the difficulty of getting the brain to accept foreign cells, and the risk of tumour development”, said Malin Parmar.
All in all, the new technique of direct re-programming in the brain could open up new possibilities to more effectively replace dying brain cells in conditions such as Parkinson’s disease.
“We are now developing the technique so that it can be used to create new nerve cells that replace the function of damaged cells. Being able to carry out the re-programming in vivo makes it possible to imagine a future in which we form new cells directly in the human brain, without taking a detour via cell cultures and transplants”, concluded Malin Parmar.

Cerebrospinal fluid leak secondary to chiropractic manipulation
http://www.surgicalneurologyint.com/article.asp?issn=2152-7806;year=2013;volume=4;issue=3;spage=118;epage=120;aulast=Kusnezov
Abstract |
Case Description: We present a case of subacute cervical cerebrospinal fluid (CSF) leak resulting from chiropractic manipulation of the cervical spine. The patient is a 29-year-old female who received manipulation one week prior to developing symptoms of severe orthostatic headache, nausea, and vomiting. Magnetic resonance imaging (MRI) revealed a new C5-C6 ventral CSF collection. Symptomatic onset corresponded with the recent cervical chiropractic adjustment. We present serial imaging correlating with her symptomatology and review the pertinent literature on complications of chiropractic manipulation.
Conclusion: Our case of ventral CSF leak with symptoms of intracranial hypotension demonstrated spontaneous symptomatic resolution without permanent neurological sequelae.

Discovery could help scientists stop the ‘death cascade’ of neurons after a stroke
So I guess I'm just popularizing the term, neuronal cascade of death, I first started using it in 2011. What do you prefer?
Death cascade
Neuronal cascade of death
apoptosis
Necrosis
Neuroprotection - boring, boring, boring
This is from January 15, 2009
http://newswire.rockefeller.edu/2009/01/15/discovery-could-help-scientists-stop-the-death-cascade-after-a-stroke/
But that no longer exists so I found it in the Wayback machine here:
http://web.archive.org/web/20130704040819/http://newswire.rockefeller.edu/2009/01/15/discovery-could-help-scientists-stop-the-death-cascade-after-a-stroke/
Distressed swimmers often panic, sapping the strength they need to
keep their heads above water until help arrives. When desperate for
oxygen, neurons behave in a similar way. They freak out, stupidly
discharging energy until they drown in a sea of their own extruded
salts. Every year, millions of victims of stroke or brain trauma suffer
permanent brain damage because of this mad rush to oblivion that begins
once a part of the brain is deprived of blood.
“We have found that you can make mice resistant to this kind of cell death by blocking one piece of the receptor without the terrible side effects you get by blocking the whole thing,” says Sidney Strickland, head of the Laboratory of Neurobiology and Genetics, who directed the research. “Now we can start exploring potential drugs to do that in humans.”
The neuronal panic that occurs when a clot or other insult blocks the flow of blood to part of the brain is called excitotoxic neurodegeneration. It results in the brain cells spitting out glutamate, which then accumulates in the synapses between neurons and stimulates the release of more glutamate. It’s a vicious cycle that kills the cells quickly and continues until blood flow is restored. Doctors often treat stroke victims by administering a heavy dose of a clot-buster called tissue plasminogen activator (tPA), a protein that can stimulate the dissolution of clots. Ironically, however, the same drug that does this crucial clot-busting also accelerates the panicky process that kills neurons, research by Strickland and others has shown. Investigating exactly how tPA does that is what led Strickland’s team to the recent discovery.
Neurons are typically couched in laminin, an extracellular matrix protein known to be involved with tPA in the neuronal “death cascade.” The Strickland lab’s experiments, published in The Journal of Cell Biology, show that tPA produces an enzyme that degrades laminin into toxic products that kill the neurons in their midst, specifically by stimulating the production of one of five subunits for a particular kind of glutamate receptor. The overproduction of this specific subunit, KA1, makes the cells hypersensitive to glutamate, which fans the glutamate frenzy leading to their death.
To better understand the process, Zu-Lin Chen and other colleagues at Rockefeller in the Strickland lab and at the University of Leicester in England designed lines of genetically modified mice that lacked either tPA or laminin specifically in the hippocampus, a region of the brain often damaged by stroke. To their surprise, they found that mice without laminin were protected from the typical neural degeneration that follows a simulated stroke in regular mice. They also found that mice with laminin but not tPA were relatively protected.
But when they injected degraded laminin into mouse brains without laminin or tPA they found a similar overproduction of the subunit of the glutamate receptor that they measured when inducing stroke in normal mice. The problem: Laminin, once degraded by tPA, prompts the proliferation of the receptor subunit that makes the cells suicidally sensitive to glutamate. By preventively injecting a molecule that disables that particular subunit, they were able to dramatically reduce the cell death following a stroke. A big plus: The treated mice did not suffer the severe side effects that come with blocking the entire glutamate receptor.
Whether this will turn into a therapy that can be applied after a stroke is uncertain.
“Can you do it after the fact? That will be a question,” Strickland says. “Cell death happens pretty quickly. But it’s an interesting avenue to pursue.”
Programmed Cell Death (Apoptosis)
With a Stroke, Discerning 'Mimic' from 'Chameleon' Can Save a Life
http://www.empr.com/with-a-stroke-discerning-mimic-from-chameleon-can-save-a-life/article/286143/#
The presentation of stroke can be complex, characterized by both false positives and false negatives. In the article "Strokes: Mimics and Chameleons" Fernandes et al address stroke-related diagnostic challenges.1 "Mimics" (false positives)—ie, non-stroke conditions that present with symptoms similar to stroke—account for up to 25% of suspected stroke presentations. A "chameleon" is a stroke that masquerades as a different disease state (false negative);1 indeed, a "seemingly infinite number" of ostensibly different clinical syndromes can turn out to be stroke.2
Despite the availability of measurement scales such as the Face, Arm, Speech, Time (FAST) score,3 or the Recognition of Stroke in the Emergency Room (ROSIER),4 diagnosis can remain elusive.1 Moreover, sophisticated imaging techniques—eg, magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) and brain computed tomography (CT)—are sensitive and specific for diagnosing stroke, but their utility declines with time following stroke onset. Therefore, the authors recommend clinical history and examination as the "reference standard," supported by brain imaging for avoiding both mimics and chameleons.

Latest Advancements in Acute Stroke Management April 17, 2013
I want to ask appropriate questions without having them dismiss my questions just because I know more than they do on the subject. Medical persons are touchy that way. You aren't important because you haven't the training to understand this complexity. My questions are going to be on what they are specifically doing to stop apoptosis or necrosis of brain cells.
You didn't mention any hypothermia in either the ambulance or the ER. Is hypothermia not yet considered ready for prime time?
The only ischemic treatment you specified in the first week is tPA. Are there no treatments in the first week that research has identified as neuroprotective or that can stop the neuronal cascade of death?
Maybe ibuprofen?, Viagra?, amantadine?, minocycline?, levodopa?, statins?, fish oil?, anti-depressants?, Paeoniflorin?, Inhalation of nitric oxide?, Melatonin?, Glibenclamide?, Etazolate?, linagliptin?, edaravone used in Japan since 2001, Enzogenol from New Zealand, Draculin?,PSD-95 inhibitors tested in monkeys.

Etanercept(Enbrel) and IBMs' Watson
Patented by Amgen.

According to an article in the March 2013 edition of Atlantic magazine titled “The Robot Will See You Now," IBM’s super computer Watson has teamed up with Memorial Sloan/Kettering Hospital to make diagnosis and treatment recommendations. IBM Watson has been programmed with 600,000 pieces of medical evidence from over two million pages of medical text as well as the entire English version of Wikipedia all stored in 15 terabytes of RAM (15 trillion bytes of memory). This is roughly equivalent to the information contained on a bookshelf that is 19 miles long.
“Computer-driven, evidence-based advice like that provided by IBM’s Watson gives validity to the off label use of prescription drugs” states Rolando Rodriguez, M.D., Neurosurgeon at Neurological Wellness Center. “The perispinal administration of the drug etanercept (Enbrel) to patients diagnosed with Alzheimer’s, stroke or traumatic brain injury (TBI) has the potential to enable a significant recovery in memory, mood, speech and physical function,” stated Dr. Rodriguez. “Doctors and nurses are drowning in information with new research popping up daily. They often don’t know what to do and are guessing as well as they can,” said Samuel Nussbaum, WellPoint’s Chief Medical Officer.
A general consensus is emerging among healthcare professionals that to effectively address the many problems in the present healthcare system in America will require a fundamental redesign, a transformation in which existing modalities are replaced by new care delivery paradigms. The expansion of computer medical decision support systems like that provided by IBM's Watson has emerged as one of the areas where there is broad support among the medical community. The proliferation of biomedical information will continue to accelerate taxing the cognitive abilities of physicians as they struggle with the weight of new research findings, clinical guidelines, and recommendations of best practices. Computerized medical decision support systems certainly have the potential to produce better outcomes, increase productivity, lower costs and reduce the occurrence of adverse events.
Perispinal injections of the drug Enbrel are an excellent example. “The medical research is clear: a single injection has the potential to produce a life-changing recovery in persons afflicted with stroke or traumatic brain injury with little to no risk to health, yet the procedure is only slowly starting to gain traction with mainstream medicine,” states Dr. Rodriguez. IBM’s Watson has the potential to be a major game changer in the field of medicine. When physicians’ diagnoses and treatment decisions are evaluated with computer-assisted 20/20 hindsight WellPoint’s Samuel Nussbaum said that “health care professionals make accurate treatment decisions in lung cancer cases only 50% of the time.” “The dictates of a capitalistic healthcare system preclude a drug like Enbrel from ever gaining FDA approval for the treatment of stroke or TBI. The estimated cost for repurposing Enbrel for treating stroke and TBI is $100 million. Considering just one to eight doses are required for the complete treatment, I can be confident this drug will never be approved for stroke or TBI” said Augusto Ramirez, M.D., of Neurological Wellness Center. Neurological Wellness Center offers a complete two-hour course on Alzheimer's treatment, stroke treatment and traumatic brain injury treatment covering all aspects of perispinal injection technique at their center in Managua Nicaragua.
For many, flying to Managua Nicaragua to receive this personalized training is an enormous expense and inconvenience. To overcome this problem, Neurological Wellness Center, under the direction of Augusto Ramirez, M.D., created Perispinal Enbrel Step-By-Step Instructional Video and accompanying e-book.
Neurological Wellness Center’s perispinal Enbrel is profoundly effective as an Alzheimer’s treatment, stroke treatment and TBI treatment. The complete treatment recommendation: for stroke is one 25mg injection of Enbrel every four days for a total of four doses over 16 days; for TBI is one 25mg injection of Enbrel every four days for a total of eight doses. This compares with Amgen/Pfizer’s FDA-approved dose schedule for moderate plaque psoriasis of 50mg twice weekly for three months followed by 50mg weekly for life. The Neurological Wellness Center’s maximum recommended dose for Alzheimer’s disease is 25mg/week for life.
The drug Enbrel is available now. Enbrel received FDA approval in 1998. Its safety profile is well understood. For Enbrel to effectively treat Alzheimer’s, stroke and TBI, it must be administered to the back of the neck precisely between the cervical vertebrae C-5 and C-6. (I wouldn't allow just any doctor to inject me at this location)This perispinal injection allows Enbrel to enter the brain by lymph drainage assisted by gravity. Fortunately for the millions of people now afflicted with Alzheimer’s, stroke and TBI, a video is now available online detailing in step-by-step fashion how to administer a perispinal injection of Enbrel,” said Dr. Rolando Rodrigues.
