Alcohol and benzodiazepines generate anxiety, panic and phobias

In almost half the patients seeking advice for anxiety, panic and phobias the cause was alcohol or benzodiazepines. In the remainder it was psychological, usually a state of conflict or a traumatic event. When symptoms are persistent following a distressing event it is often the case that alcohol or benzodiazepines are keeping them going. There is a large variation in individual vulnerability and the mechanism responsible for these symptoms is rebound arousal.
