What Causes Several Episodes Of Concussion And Anger Issues?
Consultation
Detailed Answer:
Hello and thanks for your question.
Passing out is highly unusual and is rarely a psychiatric problem. He should visit a doctor for basic bloodwork, an EKG, and possibly head imaging.
Bipolar is possible but seems unlikely. Going without sleep in bipolar disorder is usually for at least a week, which you did not mention. Perhaps he is using substances, which might also explain the passing out.
He might also have an anger issue which would be improved with psychotherapy.
