My mums behaviour seems to be getting worse. I suppose this stage started last October, initially it was only once a month, but over time the frequency of the aggression has increased. I know from reading other posts there are lots of others in a worse position. But over the last couple of weeks, there has only been two nights when my mum has not been aggressive. The thing is that during the day she is completely normal, always good humoured and loving. However once she goes to bed this all changes, she might sleep for an hour or two and will wake up suddenly and then it starts, my mum becomes a completely different person, this normally lasts for an hour or if things are bad two hours. Last night I think was the worst. I actually was really concerned for my Mums health, she just flipped and was shouting, screaming,talking no sense, banging doors, telling me that I had killed her, but it got to the stage that I thought she was having a heart attack,her breathing was all wrong and thought she was going to collapse. This lasted for about an hour, finally she went back to bed, she woke up a couple more times and seemed confused and cursed me a couple of times, but that was it. Today she is completely normal again,laughing and joking and her usual self again. I know this seems to be related to my mum falling asleep and waking up at night time. Its weird because we travel to London quite often and she never has this problem in the hotel, actually she normally sleeps through the night there. I know medication is not the answer, but I really wish this phase will pass by soon.
