Is there any possible test to tell if your gona have a stroke in near future?

Maybe...: In general, strokes come from one of three things, either an embolus (clot from the heart), blockage of the carotid artery or blockage in the arteries to the brain. Check to make sure you don't have atrial fibrillation or flutter, get a carotid ultrasound and if really concerned get an echo to look for a pfo (patent foramen ovale). At 37 unlikely to have cerebral athersclerosis, so no need to ct.
