[/INST] Hello, I believe your friend needs to be assessed for having suffered a CONCUSSION or TRAUMATIC BRAIN INJURY since he is exhibiting many of the symptoms of this problem.  Any time someone suffers a blow to the head with significant injuries to the face as your friend a concussion assessment should be performed.  Your friend should be assessed by someone with expertise in this area as soon as possible. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
