- Clinical Nuance: The term “neurosis” is largely historical and has been replaced in the DSM by specific categories (e.g., Anxiety Disorders, OCD).
- Psychotic Spectrum: Includes Schizophrenia, Schizoaffective disorder, Brief Psychotic Disorder, and Psychotic disorder due to another medical condition.
- Forensic Implication: Psychosis is a frequent basis for the insanity defense. Neurotic conditions rarely meet the legal threshold for incapacity or legal irresponsibility, as the individual usually understands the “nature and quality of the act.”
