Mental problem. For her to get cure.

Hai my mom is 48 years old. She is having hearing problem. When we consulted with the doctor they said because of anasthesya given at time of c-section delivery of baby. Now she is using hearing aid. Because of this issue she will not talk much with others. Very reserved type. Now she got sugar problem too . Nowadays she is talking to herself more frequently. Always sitting alone and thinking something bad will happen. Not knowing who is her husband and not interested to do any work. Nowadays she is not all coming out of the house. She is using abuse words to his husband itself. When we consulted this issue with one psychiatrist in Coimbatore they gave some medicine. She is taking that regularly for past 4 months but no improvement What treatment we need to take for her to get cure.
