Hi, thanks for using healthcare magic
IT may be necessary to seek psychological assistance for your father. You indicated that this behaviour started in 2010 so it is not part of his normal expected pattern of behaviour.
would be able to evaluate him and determine if there is psychiatric element to his behaviour, for example some persons with dementia
The evaluation would require that blood tests and a CT scan
of his brain be done to rule out any organic causes.
I hope this helps and that your family gets some answers soon
