Question: Hello.....my 36yr old son, had a ?TIA on Dec 13th. had experienced a couple of days prior to this event, tingling in his right fingers..he works nights, so he had just gotten up from sleeping, thought he pinched a nerve, took a shower and it went away. He had the same episode on the 13th, 40 mins went by and then...speech was not making sense, right hand and leg were "not working", said it felt like he had been drank 12 beers...PMH...unremarkable...no drugs, no cigarettes, no htn, no diabetes, 3-5 beers (if not less) on weekends..basically just overweight..he's 5'11" weight 255. at the ER, CT scan was neg...all bloodwork came back in the normal range..mag was alittle hi-- 1.9 MRA showed 6mm foci of restriced diffusion within the pons. All symptoms went away. Ultrasound of carotids was clean, echo of heart came back clear, his cholesterol was at 198, with the bad cholesterol at 124.5...he is now on aspirin, on a diet (PCP wants him to lose 95 lbs) and will go back to see his PCP on the 7th. He does get lighteheaded at times and I am worried he has a blockage somewhere in that head of his..this seems to be dissipating... what is the etiology??? Anything else we can do to ward off other 'event' and will there be one???? Thanks.....a worried mother
