I have done a search on TP, but is an anti depressant quite common place for people with dementia/alzheimers? Mum is only on 5mg Donepezil. 10 mg gave her tummy upsets. She has declined since Christmas, and our Alz Key worker suggested I take Mum to see our GP as to wether Donepezil is still beneficial and to start an anti depressant. Although I personally haven't experienced Mums mood swings, obviously Dad has. In part I do wonder how much Mums moods may be a reflection on Dads inability to cope with her and he just makes her more frustrated and confused by what he says and does.
