My 88 year old mother was diagnosed with Alzheimers 4 years ago, the progression has been fairly slow and gradual, she is pleasant and manageable, has been on the GP's Seraquel, an anxiety tablet for about 2 months now. Likes her bed and gets up late. Sometimes she sleeps for an hour after breakfast (noon-time) after her morning tablet. But recently she has been sleeping more and more during the day. Is she mercifully slipping away I wonder or is this just a phase?
