At present, this point can only be determined by "commonsense" judgments.
Once a mental disorder exists, it becomes necessary to understand it more thoroughly in order to give the proper care and treatment. For differential diagnosis, one must depend on a careful examination of the patient's history, adjustment patterns, and symptoms (as well as upon physical and neurological tests). These facts are obtained largely through interviews with the patient and his friends and relatives. Although it is customary to classify mental disorders according to one or another classification system in vogue with psychiatrists, there is a tendency today to try to understand each case in terms of the life situation and the mental mechanisms involved in the adjustment.
