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.

New Hope for Stroke Recovery

Everything here is dependent on the stroke survivor doing all the work. Why don't the doctors and researchers involved come up with solutions that prevent a lot of disability by stopping the neuronal cascade of death? Damn, does no one understand cause and effect? The rehabilitation silo barely works, only 10% get to almost full recovery.

While more people are surviving strokes, many still face long-term disability. But Johns Hopkins research finds promising ways to retrain the brain and regain independence. Here’s what experts have learned about the power of physical rehab.

Another Potential Key to Stronger Stroke Recovery
In the research, Johns Hopkins expert Steven Zeiler, M.D., Ph.D. and colleagues also found that lower levels of a protein called parvalbumin indicated that the premotor cortex had rewired after stroke. Parvalbumin marks the activity of a special class of nerve cells called inhibitory interneurons. Low levels of parvalbumin, and therefore lowered levels of inhibitory activity, is thought to help uninjured parts of the brain take over the injured parts, say researchers. This finding suggests that reducing inhibition in certain parts of the uninjured post-stroke brain (perhaps by using different medications and/or electrical stimulation) might promote recovery.
The good news about stroke: More people are surviving the initial stroke. The bad news about stroke: More people are surviving the initial stroke with disabilities which might have been minimized if they had received the kind of early, intensive physical rehabilitation that researchers find can improve function and reduce long-term disability. In fact, as many as 60 percent are left with diminished use of an arm or leg.

“When we speak about recovery we’re really talking about how the nervous system adapts to the brain missing a part of functioning tissue,” explains Johns Hopkins expert Steven Zeiler, M.D., Ph.D. “We’ve done all we could in the acute period, but the damage is done and it’s irreversible.” The question then becomes, “How do you get the remainder of the nervous system to adapt?” In other words, can we get other parts of the brain to pick up the slack? Turns out that yes, we can.

Retraining the Brain

A groundbreaking Johns Hopkins study from Zeiler and his colleagues confirmed what clinicians have long suspected—we can rewire the brain so that one part takes over functions typically handled by another, now damaged, area.

In studies conducted with mice, the researchers first taught the mice a special way to reach for food. The task is typically directed by a part of the brain called the primary motor cortex, which is involved in physical coordination. Then they gave the mice mild strokes that damaged this motor cortex. As expected, the mice could no longer perform the reaching task with their pre-stroke level of precision. Two days after the stroke, however, researchers began retraining the mice and, after a week, the mice performed the task just as well as before the stroke.

The damaged part of the brain hadn’t recovered, says Zeiler. Instead, another part of the brain called the medial premotor cortex took over. To show that, researchers gave the mice strokes in that part of the brain and saw the reaching ability again disappear. But, once again, the mice relearned the task as yet another part of the brain stepped in to handle the job of the medial premotor cortex.

In a similar study, the researchers found that the earlier retraining started, the better. “If you retrained the mice after a one-day delay they got better, but after a seven-day delay they didn’t improve,” Zeiler says.

Johns Hopkins’ Kata Project, a collaboration between neuroscientists, engineers, animal experts, artists and entertainment industry experts, has designed an immersive experience for post-stroke patients who will try to “swim” as a virtual dolphin named Bandit. Upcoming clinical trials will determine if this unique experience helps patients recover motor function faster than the current conventional treatment of repetitive exercises.

The Power of Stroke Rehab

The take-home message of the research, says Zeiler, is that “early and intense” rehabilitation—even while still hospitalized—is critical in stroke recovery. Unfortunately, that’s not always the standard practice, he says. “As a medical community we need to push for immediate and intense change in rehabilitation.”

Rehab paired with healthy living will help stroke recovery and help prevent a second stroke. If you experience an ischemic stroke (caused by a lack of blood flow to a part of the brain), your doctor will recommend aspirin or another anti-clotting medication, Zeiler says. If you have atrial fibrillation, talk to your doctor about an anticoagulation medication such as warfarin. Other smart steps to take:
