neurosis

n. any of several mental disorders involving physical and emotional symptoms (such as bodily pain, anxiety, depression, etc.) that do not stem from any obvious physiological change (Medicine)

This article describes the term in psychology. For the experimental metal band, see Neurosis (band). Neurosis, also known as psychoneurosis or neurotic disorder, is a "catch all" term that refers to any mental imbalance that causes distress, but, unlike a psychosis or some personality disorders, does not prevent or affect rational thought. It is particularly associated with the field of psychoanalysis, which is one school of thought in psychology or psychiatry.
