My wife shows symptoms of mental disorder problems. She is of 50 years old. She forgot her activities. Lack of concentration. Seems thinking more about past incidents even though they are very silly things. Not thinks about current day to day things. I remember she is having some problem since last one year. Some time talk irrelevant and do things which are not logically correct. Not interested to talk with others and watch television. Some time she sings which she never done in past. She says that she feels somebody (her father who died 4 years ago) asking her to do things which she do now, whether which are correct or not. And she is more anxious about children when they go to school and some time she goes to school to meet our children as she feels something wrong is happening or going to happen. She is very reactive for very silly things and this problem is there since the marriage- 20 years now. Kindly suggest.
