Neurosis, a term originating in Freudian psychoanalysis, refers to mental disturbances arising from suppressed anxieties, historically setting it apart from psychosis by maintaining contact with reality. Once pivotal in diagnosing anxiety-related conditions, it is now obsolete in contemporary psychiatric frameworks such as the DSM or ICD, although its influence remains in concepts like neuroticism. Scholars such as Josephine A. Jackson described neurosis as a compromise shaped by the individual’s unconscious, while C.
Lloyd Morgan examined its potential evolution into psychosis, highlighting unresolved tensions. Carl Jung regarded it as an unsuccessful adaptive strategy, and Mary F. Porter associated it with the interaction between bodily and psychological states. These diverse viewpoints illustrate neurosis as a link between inner turmoil and the conscious effort to reconcile buried desires, underscoring its continued significance in understanding human suffering.
