Recently my OH has started going to bed very early - anytime from 19:30 onwards. I've tried to get him to stay downstairs for longer but he doesn't want to. The past few days within a short time of getting into bed he starts shouting and swearing, hitting the bed/walls and slamming doors. I go up to him but am only met with abuse and asked why I've sent him to bed. I've tried talking to him calmly, suggesting he comes back downstairs, ignoring him but nothing seems to make any difference. After about half an hour he eventually goes to sleep. He's on a low dose of mirtazapine. He has FTD - one of the speech variants. I've spoken to the dementia nurse and she's referred me back to the consultant but that appointment could take ages to come through. Any suggestions as to how best to deal with this new occurrence?
