Hi and welcome to Healthcare Magic. Thanks for your question...
Since you say that he had been depressed even before the accident, it is more likely that his current psychiatric symptoms are related to the depression
. When depression becomes severe, psychotic symptoms can appear (like hearing voices, false beliefs, etc.) Moreover, since he was well enough to be sent home after the accident, it is unlikely that he would have suffered from any significant brain damage
Depression can be caused due to neurochemical imbalances in the brain and need not be stress
related always. So, it is notsurprising that he did not reveal anything to his parents. With appropriate medication and close follow up he should be able to come out of his depression.
