Hi Pankaj,
Welcome to Healthcare Magic 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 behaviour 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 behaviour.
So, I would strongly advice you to take him to a
psychiatrist, who would be able to assess him further and initiate appropriate management. There are medication which can supress such disinhibited and abnormal behaviour, 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.
