Could anyone please tell me if it's possible for a stroke to affect someone's personality. My mum has always described me as her rock & the person she depends on. She has always been a bit hostile towards my sister but since this last stroke has become really nasty towards me. Often swearing & shouting. When I pull her on her behavior towards me, she gets defensive, accused me of & making false accusations, says she has never sworn at her children. It's like she's heckle & Hyde 

Hi Lynne, unfortunately stroke can affect personality. On my stroke ward a few years ago, there was a man who became aggressive to nursing staff, especially at bed time. His wife said that before his stroke he was one of the nicest of men. It might be worth asking the doctors if mum's behaviour is indicating any other health problem.
