Depends on the cause of the strokes, so it is hard to say. Sounds like they still need to figure out why he had these strokes. Probably will get an MRI/MRA including his neck (to look for neck clots) as well as an echocardiogram to look at his heart. Also, depending on other factors, more tests may be warranted. Unfortunately, there is little that can be done acutely for strokes, so it might be a waiting game. Hope things work out.
