My father who is around 65 year old is under depression as told by some doctors. He is having sleeping disorders. Sometime he sleeps whole day and night and sometime doesn't sleep at all. Sometime he speaks too much and sometimes keeps mum. Sometimes he eats properly and most of the time deny food. Sometimes even wanna die. He says that he don't wanna live. I have consulted few doctors as well but medicines weren't much effective as of now. Also done with brain mri and other health check ups that shows normal. Please suggest what to do. Also suggest some good psychiatrist in delhi ncr area if it is really a case of depression. Also suggest the possible treatment for him.
