Therapy may help some of the symptoms but I don't believe there is an operation to prevent further strokes. Just diet and exercise (and concentration.....)

Strokes are usually caused from high blood pressure so if your bp is undercontrol it helps to prevent further strokes but, it's no guarantee because, genetics, stress, diet all play a role.

Strokes are caused from clots to the brain. These can be brought on by so many factors. Diet, exercise, diabetes, stress,dehydration, some medications can cause it,  your family genes. There is no surgery but there are anti coagulant medications and a complete change in lifestyle and attitude.My dad just survived multiple strokes, I don't wish this on anyone. Get rid of frustration and stress, calm down and look after yourself...your worth it.
