Key Facts
- Ancient civilizations such as Egypt, Greece, and Rome attributed mental illness to supernatural causes or imbalances in bodily humors, with Hippocrates proposing early naturalistic theories.
- The 18th-century reform movement led by figures like Philippe Pinel and William Tuke introduced 'moral treatment,' advocating humane care instead of chains and confinement for the mentally ill.
- Sigmund Freud's development of psychoanalysis in the late 19th and early 20th centuries shifted psychiatric focus toward unconscious processes, talk therapy, and childhood experiences.
- The mid-20th century saw a pharmacological revolution with the introduction of chlorpromazine (1952) for psychosis and later antidepressants and lithium, transforming psychiatric treatment.
- Deinstitutionalization from the 1950s onward closed many large asylums and moved care into community-based settings, shaping modern mental health services.
