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.

Analysing Patients Shortly After Stroke Can Help Link Brain Regions to Speech Functions

Useless, ABSOLUTELY NOTHING on how to fix speech problems.  The goal of stroke research is interventions that work, NOT statements that further research is needed.

Analysing Patients Shortly After Stroke Can Help Link Brain Regions to Speech Functions

Analysing the brains of stroke victims just days after the stroke allows researchers to link various speech functions to different parts of the brain, a breakthrough that may lead to better treatment and recovery, according to a study published in the journal Brain.

Tatiana Schnur, MD, Baylor College of Medicine, Houston, Texas, and colleagues evaluated the spontaneous language production of 65 patients who experienced a stroke by using storytelling. For the experiment, the patients were read the story of Cinderella and were then asked to retell it. The researchers used the Quantitative Production Analysis method and relied on 13 different measures for evaluation, including words per minute, types of words, and sentence length and formation.

They found that by evaluating patients between 1 and 13 days post-stroke, they were able to identify how different and critical components related to language production linked up with different regions of the brain. The researchers used cutting-edge techniques to relate the brain areas damaged in each individual to the degree of their impairment on these language-production measures. Specifically, they found that retrieving words and putting them into increasingly complex sentences relied on the left temporal and parietal lobes, while producing grammatical aspects of sentences relied on the left frontal lobe.

According to the authors, there are only a few other studies that have looked at patients with stroke in the acute stage, but those focused on ability to produce single words rather than providing a detailed analysis of language production. The majority of studies look at patients in the chronic stage of recovery, which is at least 6 months after the stroke. At that time, considerable reorganisation of language function in the brain may have occurred. Also, studying individuals at the acute stage allows for studying those with smaller areas of damage. Those with small lesions are likely to recover and thus not included in studies of chronic stroke, and examining these people allows for a more precise mapping between areas damaged and language abilities.

“Many patients in the chronic stage of stroke have significantly worse brain damage than acute patients and have plateaued with their recovery,” said co-author Randi Martin, Rice University, Houston, Texas. “Their brains cannot be evaluated in the same way as acute stroke patients.”

Future work will look at these same individuals at different stages during their first year of the recovery process. One important issue will be to determine what areas of brain damage and what language abilities will predict performance 1 year after stroke.

Martin hopes this work will help better understand how different brain regions recover from stroke. She expects the work will be useful in the design of treatment options for patients who have experienced a stroke, including early interventions that may boost long-term recovery.
