Doctor: HelloThanks for using Health Care Magic for posting your query.I have gone through your question in detail and I can understand what you are going through.There is a definate change in your fathers personlaity. The most common cause is onset of cognitive disorders like dementia. This leads to such personality changes. The other possibility could be a mass lesion inside the brain. Considering his age, it would be wise to get a CT scan brain done.Hope this helps,If you have any further query, I would like to help you on the link:bit.ly/dr-srikanth-reddyWish you good health,Kind regardsDr. Srikanth Reddy
