My husband's first TGA was October 2003. Then again in November 2006, May of 2016, and again in March 2019. He was also assured it was rare and unlikely to recur. In October of 2024 he was diagnosed with MCI consistent with Cerebral Amyloid Angiopathy, micro bleeds observed in MRI. Cognition is delayed, he has less short term memory, more confusion, especially with increased sensory overload, too much conversation in the room, too many people, etc. No evidence of stroke, but he's had right sided weakness, etc. since last October. He uses a walker or alpine poles to walk. He no longer drives, because he says he can’t process changes quickly enough to drive safely. Also being followed for anemia. We are still in stages of trying to define his dementia, which is not Alzheimers, but nontheless is changing and increasing daily. There is some thought that he had brain micro bleeds all along, undetected in his four TGA episodes. There is a lot that's unknown. We in the family can track cognitive changes back to 2017, but they were not considered relevant until they escalated.
