My mum was diagnosed with mixed dementia (Alzheimer's and vascular dementia) at the start of this year. She was prescribed Donepezil and Pregabalin to help with anxiety and aggression. However she is still having aggressive episodes, which seem to occur late afternoon and into the evening. These are often for no obvious or apparent reason. Her mood will suddenly change and she will walk around the house, slamming doors, banging things, even hitting me or my dad. (I live in the same house, although my dad is my mum's main carer). My mum will say she's leaving or going for a walk. We've heard about sundowning so not sure if that's part of what's going on. It can be so difficult to calm her down, and we've read it's best to walk out of the room. But we are worried she'll hurt herself or damage the house. Has anyone else experienced this, what did you do and how long did the aggressive episodes go on for? Thanks
