Stroke is the leading cause of adult disability, because most patients do not fully recover from effects of a stroke. Also, rehabilitation after a stroke is limited because most patients cannot sustain the rehab intensity needed for stroke recovery. Enter the first stroke rehabilitation drug to repair brain damage. Researchers at UCLA report with laboratory animals and with stroke patients experienced loss of a brain connection distant from the stroke site. They created a drug that helps the brain network rebuild, even better than physical rehab. Authors of the study in Nature Communications caution that further research is needed to understand the safety and efficacy of the new drug before a formal human trial can be considered.
