I also have small vessel ischemic disease & APS (antiphospholipid syndrome) which has caused 3 strokes and numerous TIA's. So I can't say whether any one event might be from something other than the APS & SVID. However, my 'events' were more typical motor loss on one side vs aphasia.

I think (I use this loosely) my temporal lobe dysfunction (found on EEG) is from the Sjogren's inflammation on the brain and contributes to my cognitive problems in general, not 'episodes' of a specific type.

Was the MRI you had immediately after one of these episodes? What about an EEG...have you had one?
