My mum was diagnosed with AD in 2003, up until now things have been ok, but now during the night my mum wakes up a couple of times suddenly and can loose her temper, although she is not violent physically, I am concerned, it has hard to make out what my mum is saying at times when she looses her temper, sometimes she will say she wants to go home even though she is home, I try and change the subject and try to reassure her, but this does not always work and my mums temper can be quite severe, it can last for anything from 10 minutes to over an hour. My mums psychiatrist says just to monitor the situation as he does want to prescribe any medication, why would he not prescribe something ? Any experiences, help would be much appreciated.
