Mum has slowly been slipping into dementia for nearly 4 years now with my father her main carer. Diagnosis has recently been given but medication refused. My main worry has become my father. He is withdrawn, and becoming a little forgetful and confused at times himself. He avoids any attempt I make to meet up on his own to discuss everything. My obvious worry is the dreaded dementia again but wonder if these symptoms could be a result of stress and depression. Any thoughts?..
