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.

Methods from optogenetics, machine learning should help improve treatment options for stroke patients

Don't just lazily say should and then never followup with actual inteventional treatment options. I bet nothing will occur; NO leadership, NO strategy.

Heidelberg researchers develop computer vision technique to analyze rehabilitation process
Methods from optogenetics and machine learning should help improve treatment options for stroke patients. Researchers from Heidelberg University have developed a computer vision technique to analyze the changes in motor skills that result from targeted stimulation of healthy areas of the brain. Movements recorded with a video camera are automatically analyzed to monitor the rehabilitation process and evaluate and adjust the optogenetic stimulation. Researchers from the Interdisciplinary Center for Scientific Computing (IWR) in Heidelberg worked with neurobiologists from Switzerland to develop the method.
Along with speech and vision problems, motor paralyses are the most common symptoms post-stroke. According to lead author Dr Dr Anna-Sophia Wahl, a neuroscientist at the Swiss Federal Institute of Technology (ETH) in Zurich, neurorehabilitation is the only treatment option for the majority of stroke victims. "Many approaches in basic science and in the clinic aim to trigger regeneration processes post-stroke by stimulating healthy brain regions of indeterminate size. However, we use optogenetics to systematically stimulate certain unaffected areas of the brain so that they sprout connections into the damaged hemisphere in order to assume its functions." So-called corticospinal circuits from the cerebral cortex to the spinal cord are specifically activated.
In optogenetics, light is used to control genetically modified cells. The cooperation partners in Switzerland - researchers from the ETH and the University of Zurich - used optogenetic stimulation in combination with intensive rehabilitation training to restore the paralysed paw function in rats. "Using our automatic evaluation of the movement processes, we were able to demonstrate a full recovery," explains Prof. Dr Björn Ommer, IWR researcher and head of the Heidelberg team. The new computer vision technique is able to quantify even the slightest changes in motor functions. "By recording and analyzing the movements, we can objectively assess whether there was true restoration of the original function or merely compensation."
