Computer Game Helps Return Vision to Stroke Victims

Computer Training Helps Return Vision to Stroke Victims
Despite all the negative things people say about video games, we've recently learned that playing them can help to improve your eyesight. If that doesn't convince you that video games can have positive effects, then take a look at this: According to Reuters, scientists are successfully using a type of primitive video game to rehabilitate stroke victims' debilitated vision. Amazingly, the method has been able to return as much as 90-percent of some patients' vision.

As part of the project, researchers at the University of Rochester Eye Institute show screened images of dots and other visual artifacts to stroke victims, asking the patients to identify the shapes. Patients often say that they can see something, even if they can't tell what it is. But, when asked to guess what they're seeing, they often guess correctly. Although strokes can result in brain damage, the eyes are left intact. This means the victims just need to be taught how to process those visual signals again. That's exactly what the program does, and some patients have regained enough of their eyesight to even return to driving.

Maybe this is another good reason to get Wii consoles at retirement homes. [From: Reuters]

New Device Treats Strokes, Removes Blood Clots

Penumbra strokes blood clotsA new device will help victims of severe strokes avoid debilitating complications. Named Penumbra, the vacuum cleaner-like tool removes blood clots that starve the brain of oxygen and lead to paralysis or permanent brain injury. While some patients need blood clots cleared by a drug called TPA, they do not always receive the treatment within three hours of suffering a stroke, the time frame in which the drug is effective. Penumbra, on the other hand, can be used up to eight hours after the stroke, or if TPA is ineffective (which occurs 70% of the time).

The device works by suctioning out blood clots, piece by piece, until blood flow is restored. The small tube reaches the brain via implantation by doctors in a blood vessel near the groin. Doctors caution that it is not always wise to unclog blood clots, as newly cleared vessels bombard the brain with blood, which can produce swelling or a brain hemorrhage. Brain scans help determine whether or not blood clots should be cleared. Overall, it seems that using Penumbra can mean the difference between major and minor complications from strokes, the number three killer of Americans.
