Depressive mood swings can affect people of both sexes and every age. This book describes the causes, symptoms and treatment of depressive moods. Dr McKeon discusses fully the ways in which mood swings can be recognized - the signs of depression and its opposite, an unnatural elation. He also reveals the problems that can arise if the illness is not diagnosed - it may lead to alcohol dependence, overspending, sexual excess, and even, if the depression is deep enough, to suicide. He gives advice on how patients and their families can learn to cope and points out that most sufferers come to term with and accept the problem.
