So just last week I was feeling very irrational, experiencing behavioural changes, forgetfulness, confusion and lack of attention. This week I've been more aggressive, talking to myself, difficult to get to sleep, twitching, isolating myself and not talking to people. I have no idea what is going on and I was looking up the symptoms and it might be young onset dementia or frontotemporal dementia. But I'm not 100% sure it is so I was wondering if it might be something else other than that. I think I had a concussion or something like that in the past.
