Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

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's quite disgusting that this information is not available from every stroke association and doctors group.

Study finds abnormally low blood flow in the brain of marijuana users

 It is vastly more likely that people with low blood flow are self-treating themselves with marijuana to feel better. Taken from neuropsychiatric clinics which pretty much proves my point.  These doctors need to learn about cause and effect.  This all probably part of a concerted effort by the drug industry to prevent a non-patentable drug from entering the marketplace. Over 500,000 stroke survivors a year in the US could be treated better with marijuana.  Don't fall for these negative articles.

My 13 reasons for marijuana use post-stroke.  

But don't listen to me, I have absolutely no medical training. You are going to have to figure out how to dose yourself since your doctor will know nothing and no one will do translational research until our fucking federal legislators legalize it.

As the U.S. races to legalize marijuana for medicinal and recreational use, a new, large scale brain imaging study gives reason for caution. Published in the Journal of Alzheimer's Disease, researchers using single photon emission computed tomography (SPECT), a sophisticated imaging study that evaluates blood flow and activity patterns, demonstrated abnormally low blood flow in virtually every area of the brain studies in nearly 1,000  marijuana compared to healthy controls, including areas known to be affected by Alzheimer's pathology such as the hippocampus.
Hippocampus, the brain's key memory and learning center, has the lowest blood flow in marijuana users suggesting higher vulnerability to Alzheimer's. As the U.S. races to legalize marijuana for medicinal and recreational use, a new, large scale brain imaging study gives reason for caution. Published in the Journal of Alzheimer's Disease, researchers using single photon emission computed tomography (SPECT), a sophisticated imaging study that evaluates blood flow and activity patterns, demonstrated abnormally low blood flow in virtually every area of the brain studies in nearly 1,000 marijuana compared to healthy controls, including areas known to be affected by Alzheimer's pathology such as the hippocampus.
All datawere obtained for analysis from a large multisite database, involving 26,268 patients who came for evaluation of complex, treatment resistant issues to one of nine outpatient neuropsychiatric clinics across the United States (Newport Beach, Costa Mesa, Fairfield, and Brisbane, CA, Tacoma and Bellevue, WA, Reston, VA, Atlanta, GA and New York, NY) between 1995-2015. Of these, 982 current or former marijuana users had brain SPECT at rest and during a mental concentration task compared to almost 100 healhty controls. Predictive analytics with discriminant analysis was done to determine if brain SPECT regions can distinguish marijuana user brains from controls brain. Low blood flow in the hippocampus in marijuana users reliably distinguished marijuana users from controls. The right hippocampus during a concentration task was the single most predictive region in distinguishing marijuana users from their normal counterparts. Marijuana use is thought to interfere with memory formation by inhibiting activity in this part of the brain.
According to one of the co-authors on the study Elisabeth Jorandby, M.D., "As a physician who routinely sees marijuana users,  what struck me was not only the global reduction in blood flow in the marijuana users brains , but that the hippocampus was the most affected region due to its role in memory and Alzheimer's disease.  Our research has proven that marijuana users have lower cerebral blood flow than non-users. Second, the most predictive region separating these two groups is low blood flow in the hippocampus on concentration brain SPECT imaging. This work suggests that marijuana use has damaging influences in the brain - particularly regions important in memory and learning and known to be affected by Alzheimer's."
Dr. George Perry, Editor in Chief of the Journal of Alzheimer's Disease said, "Open use of marijuana, through legalization, will reveal the wide range of marijuana's benefits and threats to human health.  This study indicates troubling effects on the hippocampus that may be the harbingers of brain damage."
According to Daniel Amen, M.D., Founder of Amen Clinics, "Our research demonstrates that marijuana can have significant negative effects on brain function. The media has given the general impression that marijuana is a safe recreational drug, this research directly challenges that notion.  In another new study just released, researchers showed that marijuana use tripled the risk of psychosis. Caution is clearly in order."
