Could do with some advice. My OH is acting oddly. He is struggling to carry out tasks that he would normally be able to do without even thinking, just small things but quite a lot. He seems to be sleeping at night quite well at the moment, which is unusual for him, but during the day he falls asleep at the drop of a hat. I went to the kitchen to get him something and by the time I got back into the living room he was fast asleep. He gets severe headaches and has to take painkillers for this and always says its because he has taken painkillers. He doesn't seem to be able to follow things like conversation or a tv programme, and gets agitated about this. His mood seems flat, says he doesn't really feel anything. He has had three of these episodes over the past 12 months and the gp and neurologist don't seem to be able to find any reason for them. The episode lasts for a week or so and then he's back to 'normal' for months. I looked up Lewy Body Dementia and the symptons sound similar.
