n. (pl. neuroses)
any long-term mental or behavioural disorder in which contact with reality is retained and the condition is recognized by the sufferer as abnormal. A neurosis essentially features anxiety or behaviour exaggeratedly designed to avoid anxiety. Defence mechanisms against anxiety take various forms and may appear as phobias, obsessions, compulsions, or sexual dysfunctions. In recent attempts at classification, the disorders formerly included under the neuroses have been renamed. The general term is now anxiety disorder; hysteria has become conversion disorder; amnesia, fugue, multiple personality, and depersonalization are dissociative disorder; obsessional neurosis is now known as obsessive-compulsive disorder (see obsession)}}; and depressive neurosis has become dysthymic disorder (see depression) in DSM-IV. Psychoanalysis has proved of little value in curing these conditions and Freud's speculations as to their origins are not now widely accepted outside Freudian schools of thought. Neurotic disorders are probably best regarded as being the result of inappropriate early programming. <
neurotic adj.

neu·ro·sis (n-roґsis) pl. neuroґses [neur- + -osis] 1. former name for a category of mental disorders characterized by anxiety and avoidance behavior. In general, the term refers to disorders in which the symptoms are distressing to the person, reality testing is intact, behavior does not violate gross social norms, and there is no apparent organic etiology. Classified in DSM-IV under anxiety disorders, dissociative disorders, mood disorders, sexual disorders, and somatoform disorders. 2. in psychoanalytic theory, the specific etiological process that gives rise not only to neuroses as defined above but also to personality disorders (formerly called character neuroses to emphasize this) and some psychotic disorders. Unconscious conflicts involving opposing wishes or forbidden infantile wishes give rise to an unconscious anticipation of danger (experienced as anxiety) in situations that activate a conflict, and anxiety serves as a signal to trigger unconscious defense mechanisms, the operation of which is visible to the conscious mind and to observers in the form of neurotic symptoms or pathological personality traits.
