Hi, my 83 year old mum has mixed dementia diagnosed 2 years ago. She also has SAD, burning mouth syndrome and a pacemaker. She is constantly complaining of headaches and sits around in a hat most of the time. I've asked drs if this is a symptom but they don't confirm one way or the other. We live close and I am in with her every day. I cook her meals, take her shopping, to appointments etc whilst working full time. My sibling is her everythingcomes when it suits and when I ask them to stay with her so I get a break, has every excuse going why they cant. I am exhausted. If be grateful for any thoughts or advice.
