My dad has Dementia and has got worse during lockdown, mum is now struggling to cope with him. She admitted today dad was getting more and more aggressive and it’s harder to find ways of distracting him. Today he doesn’t know who mum is, keeps asking for his wife,. die to lockdown I’ve been unable to visit and provide support to mum. I think she’s had enough now, she’s tired and is feeling alone. I’m not sure what to do. Any advice please.
