My dad is 74 and has always been very chilled. He's a different person. Angry, confrontational, aggressive, paranoid. Things are "being stolen" (for example someone has stolen a packet of biscuits from his car and re locked it) and people are "talking behind my back." He sees ghosts. He gets lost and confused at night, once sleeping naked in the dog basket (commenting 'I'll sleep anywhere). Memory clinic discharged him saying he'd had two TIAs but no sign of dementia. Things are quickly getting worse. In my eyes he is an alcoholic. He is dirty, scruffy and his language is embarrassing. He used to be so proud and smart. I'm getting no help from GP despite hammering their door down. What else can I do? I'm losing my lovely dad xx
