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 injury causes impulse control problems in rats

I have no impulse control problems. However my anger is righteous and directed at the correct stroke medical 'professionals'.

New research from the University of British Columbia confirms for the first time that even mild brain injury can result in impulse control problems in rats.
The study, published in the Journal of Neurotrauma, also found that the problems may be linked to levels of an inflammatory molecule in the brain, and suggest that targeting the molecule could be helpful for treatment.
"Few studies have looked at whether traumatic brain injuries cause impulse control problems," said the study's lead author, Cole Vonder Haar, a former postdoctoral research fellow in the UBC department of psychology who is now an assistant professor at West Virginia University. "This is partly because people who experience a are sometimes risk-takers, making it difficult to know if impulsivity preceded the brain injury or was caused by it. But our study confirms for the first time that even a can cause impulse control problems."
For the study, researchers gave rats with brain injuries a reward test to measure impulsivity.
Rats that were unable to wait for the delivery of a large reward, and instead preferred an immediate, but small reward, were considered more impulsive.
The researchers found that impulsivity in the rats increased regardless of the severity of the brain injury. The impulsivity also persisted eight weeks after injury in animals with a mild injury, even after memory and returned.
"These findings have implications for how are treated and their progress is measured," said Vonder Haar. "If physicians are only looking at memory or motor function, they wouldn't notice that the patient is still being affected by the in terms of impulsivity."
After analyzing samples of frontal cortex brain tissue, the researchers also found a substantial increase in levels of an inflammatory molecule, known as interleukin-12, that correlated with levels of impulsivity. Interleukins are groups of proteins and molecules responsible for regulating the body's immune system.
The study builds on the researchers' previous findings about the link between interleukin-12 and impulsivity.
Catharine Winstanley, the study's senior author and associate professor in the UBC department of psychology, said the findings are important because impulsivity is linked to addiction vulnerability.
"Addiction can be a big problem for patients with traumatic brain injuries," she said. "If we can target levels of interleukin-12, however, that could potentially provide a new treatment target to address impulsivity in these patients."
