I've been told by several experienced persons that most Alzheimers sufferers are on antidepressants. Is this true? Our Mum is really low these last three months, sad, quiet and weeping, but the doctor is reluctant to prescribe them. She is on the lowest dose of galantamine now and I suspect this will be discontinued soon as her cognitive abilities have deteriorated. I think the depression is because, despite her deterioration, she still has sufficient awareness to know she is losing her memory and she is frightened despite everything we do to reassure her.
