<s>[INST] hello sir, This is in reagrds to my Father who is in 50+ now. he has never acted like a mature man as per his age. He never feels like to do anything.Only he wants to eat alot n abuse if his expectations are not fulfilled in tearms of money or food.Earlier his treatment was started at AIIMS but my grandmother interrupted that saying he is not mad. Pls suggest if this is mental illness..can it be cured, if yes how.. i wud b very thankful to u.. [/INST] Hi well come to Chat Doctor. His symptoms are suggestive of ?schizophrenia. Since she has habit of abusing and not having self-control and socially with Chat Doctor.  It seems he's having since long, so he is in chronic stage. Yes you can definitely get help from psychiatrist but difficult to cure him because of chronicity of disease. He has to be under regular check up and regular psychotherapy if recommended by psychiatrist.  </s>
