My brother 35 is getting unconscious for half an hour from a week. First stroke was for 2 hours and then in second day had another stroke for an hour. On fourth day had 4 strokes each lasting for almost half an hour. He doesn't pee nor his teeths are tightly closed while getting unconscious. He feels pain in head before and pain around heart after stroke. BP normal, ECG normal MRI shows nonspecific leukoaraiosis. He is having some immense tension from family problems. He also smoke.
