<s>[INST] Dear Sir, My father is 77 yrs. And a widower. He has been suffering from excessive/compulsive sexual desires, resulting in him asking our maids for sex or he is also showing pornograpChatDoctoraterial to kids even. No amount of persuasion has worked. We have been suggested by a relative to take him to a mental/psychiatric hospital for proper treatment. Please advise. Regards PB [/INST] Hi Pankaj, Welcome to Chat Doctor, and thanks for your question... Firstly, the symptoms which your father is having definitely requires immediate attention. The reason is not only could he get himself into trouble, but he also poses a serious threat to others around him.  Secondly, such recent changes in behavior or personality can often be a consequence of a brain pathology, and thus needs prompt evaluation. Disorders involving the frontal lobe of the brain, like frontal lobe dementia, vascular problems, etc. are typically known to cause such kind of disinhibited behavior. So, I would strongly advise you to take him to a psychiatrist, who would be able to assess him further and initiate appropriate management. There are medication which can suppress such disinhibited and abnormal behavior, but he needs a thorough and proper evaluation before that. Therefore, please do not delay further and take him to a psychiatrist ASAP. All the best. -  </s>
