Deans' stroke musings: Early intervention with electrical stimulation reduces neural damage after stroke in non-human primates

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.

Early intervention with electrical stimulation reduces neural damage after stroke in non-human primates

This means your competent? doctor and hospital will IMMEDIATELY GET HUMAN TESTING GOING! Oh no, they're incompetently DOING NOTHING!

Abstract

For patients experiencing ischemic stroke, acute intervention offers the most critical therapeutic opportunity as it can reduce irreversible tissue injury and improve functional outcomes. However, currently available treatments within the acute window are highly limited and have strict patient selection criteria. Although emerging neuromodulation techniques have been proposed as a treatment for chronic stroke, acute stimulation is rarely studied due to concerns about exacerbating ischemia-induced electrical instability. Here, we demonstrate that acute cortical electrical stimulation, administered one hour post-stroke, provides neuroprotection in non-human primate brains. Using advanced electrophysiology and histology tools, we found that applying continuous theta burst electrical stimulation directly adjacent to the ischemic lesion significantly reduced neural activity in the surrounding tissue, as evidenced by lower electrocorticography signal power and c-Fos expression. This reduced depolarization was accompanied by decreases in neuroinflammation and infarct volume in the sensorimotor cortex. These findings suggest that acute electrical stimulation may serve as a safe and effective early intervention, offering a promising therapeutic strategy to improve outcomes in ischemic stroke.
