Hello and welcome to Healthcare Magic. Thanks for your query.
A recent onset change in behaviour or personality could be due to the following possibilities:
- Related to the brain injury
- frontal lobe
injuries can typically present with personality cahnges, disinhibited behaviour, emotional lability, sexual inappropriateness, etc.
- A superimposed of underlying psychiatric disorder which could be the cause for the recent worsening. For examples, psychotic disorders, mood disorders
- like a hypomania
If his agitation and inappropriate behaviour is quite troublesome and difficult to handle, there are medication (such as anti-psychotics or mood stabilizers) which can help him calm down. Please consult a psychiatrist
for a detailed evaluation and further treatment.
Wish you all the best.
