I'm in my 50s and sometimes I can't work the TV remote, does this mean I have dementia?
Perhaps if I constantly walked out the house leaving the door open to walk into town to speak loudly in the town square, half dressed would be a sign?
Or that I had no idea who I was talking to despite the fact, I'd just been told would be a sign?
Or that I left the dinner cooking to such an extent that it burnt black and nearly caused a fire would be a sign?
Or that I refused to speak, to eat, to do my ablutions would be a sign?
Or that I hollered at my dearest daughter, who the feck are you and what are you doing in this house is a sign?
Or that I allowed a cold caller into the house and treated them as a long lost cousin from, where was it you were from? Would that be a sign?
