My brothers and I are very concerned because our father's behaviour has become increasingly erratic and difficult over the past 6 months or so. He has never been easy but it has got much worse and he is saying weird and irrational things, being aggressive/insulting towards us with no clear reason and so on. Major mood swings. He lives on his own and can basically care for himself ok but his memory has become poor (he forgets arrangements that have been made etc). We are starting to put two and two together (and maybe making five) and that's what prompted me to post on this forum. He is late sixties, so not that old, but he is also a heavy drinker so that could be a factor. It is impossible to deal with him to get him to seek proper medical help (in fact he has been so terrible to each of us, separately, that we are not on good terms at the moment). None of us live that close to him to know his GP.
Basically, we think we need some advice, to talk to someone who might have an idea about what's going on and where to go from here so that we can do the right thing. Can anyone please suggest where we might get this type of advice as we are currently stuck, especially as there is no diagnosis as such. Thanks!
