Classification is a process by which phenomena are organized into categories so as to bring together those phenomena that most resemble each other and to separate those that differ. Any classification of psychiatric disorders, like that of medical illnesses, should ideally be based on a etiology. For a large majority of psychiatric disorders, no distinct a etiology is known at present, although there are many attractive probabilities for several of them. Therefore, one of the most rational ways to classify psychiatric disorders at present is probably syndrome. A syndrome is defined as a group of symptoms and signs that often occur together, and delineate a recognizable clinical condition.
