Washington: A new study has revealed that approximately 14 percent of all strokes occur during sleep, preventing many from getting clot-busting treatment."Because the only treatment for ischemic stroke must be given within a few hours after the first symptoms begin, people who wake up with stroke symptoms often can`t receive the treatment since we can`t determine when the symptoms started," said study author Jason Mackey, of the University of Cincinnati and a member of the American Academy of Neurology.
The researchers also analyzed whether those with wake-up strokes would have been eligible for the clot-busting drug tissue plasminogen activator, or tPA, if the time of stroke onset had been available. Of the 273 wake-up strokes, at least 98 would have been eligible for treatment.The study was recently published in the- print issue of Neurology.ANI
