R. P. may be suffering a stroke or psychological problems. Your family should discuss the possibility of taking you to specialist doctors who can quickly diagnose his case and provide correct treatment.
Explanation:
As seen in the question above, R.P. is showing signs of drunkenness, even though he has not drunk any alcoholic beverage for years. This can indicate psychological problems, showing the need of the R.P. family to take him to a psychiatrist who can help him.
However, R.P. may be showing signs of stroke. These signs can be mistaken for drunkenness, because stroke causes the death of some brain cells, as it does not allow the region where these cells are to be irrigated with blood. In that case, the R.P. family should immediately call an emergency service that will help him as soon as possible.
