Neurosis is a class of functional mental disorders involving distress but neither delusions nor hallucinations, whereby behavior is not outside socially acceptable norms. The state of research on neurosis has moved towards looking at biological and genetic substrates or mechanisms underlying neurosis. The recent literature shows acceptance of common mental disorders such as Generalized anxiety disorder (GAD), Panic disorder (PD), and Obsessive-compulsive disorder (OCD), across cultures replacing neurotic disorder. Usage of the diagnosis of neurosis has been decreased, and replaced by newer categories in the current popular classificatory systems. In the International Classification of Diseases (ICD-10), all disorders regarded as neurosis remained together but under the division of rubric 'neurotic, stress-related and somatoform disorders'. In the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), neurosis has been eliminated as a category.
