Why does my brother have a panic attack during office parties?

During office parties, my brother chokes. He does not want to talk to other people and is being criticized even by his friendly associates. He never resorted to astrology before, but I thought it could be the cause of his anxiety. I would want to get some areas shown to support him to calm down and be less apprehensive about professional social environments.
