After a stroke, there is an increased risk of suffering a second one. Until now, it was known that if areas in the left hemisphere were affected during the first attack, language is often particularly impaired. In order to maintain the language capabilities, the brain usually drives up neighboring areas and briefly also the counterparts on the right side. As Scientists now found out, that the right hemisphere seems to play a constructive role in maintenance of function following big lesions as well as repeated strokes. These findings can help to improve therapy for those affected.
