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.

Video: This visualization of a human heart could help doctors predict stroke

This wouldn't have helped me at all. I had the heart of an athlete. But for some it could be useful.

Strokes kill someone every 4 minutes. To determine your risk, doctors measure certain characteristics of your heart, such as its size and pumping strength. However, researchers haven’t had the tools to study how disease-induced structural changes in the heart might be affecting heart function and blood flow. Now, an interdisciplinary team of scientists says it has found a new way to analyze blood flow through one of the heart’s upper blood collection chambers—the left atrium—which could lead to a better way to assess stroke risk in patients. The researchers used specialized computerized tomography scans to build visualizations of cardiac blood flow in two hearts: one with healthy blood flow (above) and another with abnormal blood flow because of heart disease. Their modeling shows that in the healthy heart, blood flows through the left atrium in a tight corkscrew shape, which allows blood to quickly exit that structure. However, in the enlarged, diseased heart, this corkscrew shape never fully forms, which causes blood to linger in the left atrium. As a result, the blood is more likely to pool there, forming a stroke-causing clot, the team reports this month in the Annals of Biomedical Engineering. The scientists hope that future work will enable them to equip medical practitioners with the ability to use computerized, personal cardiac blood flow visualizations to assess stroke risk in their patients.
