The compulsive neurotic is a repressed rebel who lives in constant conflict between autonomy and submission. He can never express his instinctual needs and emotions; he has learned to mask his feelings and express them through compulsive rituals. This book presents, based on psychodynamic therapy, possibilities for diagnosis and treatment applicable to all therapeutic schools. Compulsions are among the most common mental disorders. Typical symptoms of individuals with a compulsive disorder include rumination, counting, washing, or checking compulsions. Many lose vitality and flexibility, frequently question themselves, and constantly hesitate. This book explains the symptomatology, classification and epidemiology, psychodynamics, pathogenesis and etiology, as well as the relationship to depression, schizophrenia, and hoarding disorder, along with deep psychological therapy.
