Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 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:

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.

Brain halves increase communication to compensate for aging, study finds

You'll have to ask your doctor how to accomplish this with EXACT stroke protocols.

Increased communication between distant brain regions helps older adults compensate for the negative aspects of aging, reports a new study published this week in Human Brain Mapping.
The aged tends to show more bilateral than the young brain. While this finding has been observed many times, it has not been clear whether this phenomena is helpful or harmful and no study has directly manipulated this effect, until now.
"This study provides an explicit test of some controversial ideas about how the brain reorganizes as we age," said lead author Simon Davis, PhD. "These results suggest that the aging brain maintains healthy cognitive function by increasing bilateral communication."
Simon Davis and colleagues used a brain stimulation technique known as transcranial magnetic stimulation (TMS) to modulate brain activity of healthy while they performed a memory task. When researchers applied TMS at a frequency that depressed activity in one memory region in the , communication increased with the same region in the , suggesting the right hemisphere was compensating to help with the task.
In contrast, when the same prefrontal site was excited, communication was increased only in the local network of regions in the left . This suggested that communication between the hemispheres is a deliberate process that occurs on an "as needed" basis.
Furthermore, when the authors examined the white matter pathways between these bilateral regions, participants with stronger white matter fibers connecting left and right hemispheres demonstrated greater bilateral communication, strong evidence that structural neuroplasticity keeps the brain working efficiently in later life.
"Good roads make for efficient travel, and the brain is no different. By taking advantage of available pathways, aging brains may find an alternate route to complete the neural computations necessary for functioning," said Davis.
These results suggest that greater bilaterality in the prefrontal cortex might be the result of the aging brain adapting to the damage endured over the lifespan, in an effort to maintain normal function. Future brain-stimulation techniques could target this bilateral effect in effort to promote communication between the hemispheres and, hopefully, engender healthy cognition throughout the lifespan.
