[/INST] Hello and welcome to Chat Doctor. Thanks for your query. I understand your concern regarding your mothers psychological problems. Now, increased irritability and anger, mood changes, poor food intake, poor self-care, etc. in elderly persons could be indicative of a depression. However, we need a detailed history and a proper psychological assessment to make a definitive diagnosis. I would suggest that you take her to a psychiatrist for a detailed psychological evaluation and further management. Don't worry, there are effective treatment options - in the form of medication or counselling / psychotherapy which will help overcome you mothers problems. Wish you all the best.  </s>
