This excellent guide offers help to those who suffer from panic anxiety. Part 1 discusses panic-like symptoms and their relation to both physiological and psychological disorders, while Part 2 recommends ways to eliminate or reduce those symptoms. As the book explains, psychological panic disorder is the body's emergency response, inappropriately triggered by a faulty belief system, to a situation perceived as threatening. Sufferers are given the tools to restore calm, including the means to develop an internal ``supportive observer'' that can assess the situation more accurately, provide alternative courses of action, and draw attention away from negative, self-defeating thoughts. For therapists as well as their clients. Bonnie Hoffman, C.S.W., North Fork Counseling Service, Mattituck, N.Y.
