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.

Keeping your synapses sharp: How spermidine reverses age-related memory decline

If true, how many decades before your doctor finds out about this? And how many decades after that will a stroke protocol be written? I'm betting never. You are fucking screwed along with all future stroke survivors. We have got fucking idiots in charge of stroke.
And look, already 3 years have passed;

Administering Natural Substance Spermidin Stopped Dementia Sept. 2013


http://medicalxpress.com/news/2016-10-synapses-sharp-spermidine-reverses-age-related.html
Synapses, connecting the neurons in our brains, continuously encode new memories, but the ability to form new memories ("learning") diminishes drastically for many of us as we get older.
In the article published September 29 in open-access journal PLOS Biology, work by the groups of Stephan Sigrist from the Freie Universität Berlin, Andrea Fiala (Universität Göttingen) and Frank Madeo (Universität Graz) now shows that specific changes at the level of synapses directly provoke age-related dementia, and that, however, administering a simple substance already found in our bodies, spermidine, can help to avoid such age-related synaptic changes and thereby protect from age-induced memory impairment.
Just like humans, the fruit fly Drosophila melanogaster - a leading model for aging research - suffers from memory impairment with advancing age. The same team of researchers previously observed that Drosophila exhibits an age-induced decline in levels of spermidine, and that these memory deficits can be suppressed by feeding with a diet supplemented by spermidine. They now describe an unexpected scenario that convincingly explains the suppression of by spermidine feeding. In a nutshell, synapses within the Drosophila brain seem to narrow their operational space, and thus become increasingly unable to form with age.
Dietary supplementation with spermidine, however, prevented these changes. Importantly, when the authors mimicked these age-associated changes by genetic means, learning suffered even in young flies, providing a causal link between generic synaptic mechanisms and age-induced memory impairment. This work promises to open up a new avenue when searching for new therapeutic strategies to fight age-associated dementia, a major health threat of our times.
