A short history of psychiatry
- Topic
From early asylums to moral treatment, diagnosis by course, psychoanalysis, the first psychiatric medicines and care in the community.
What it is
Modern psychiatry took shape in the early 1800s, when reformers such as Philippe Pinel and William Tuke promoted humane care of people with mental illness (moral treatment), which inspired the first public asylums. In the late nineteenth century Emil Kraepelin sorted the major psychoses by their course into dementia praecox and manic-depressive illness, and in 1911 Eugen Bleuler renamed dementia praecox schizophrenia. Psychoanalysis then shaped psychiatry for about half a century. From 1952 chlorpromazine transformed treatment, and after 1955 large mental hospitals emptied as care moved to the community, while DSM-III (1980) brought explicit diagnostic criteria.
Key facts
- The public asylums began as small therapeutic hospitals but became large, overcrowded institutions focused on containment.
- Kraepelin did not believe that single symptoms identify an illness; a disorder is a combination of symptoms plus its course over time.
- Laborit saw that chlorpromazine produced indifference without loss of consciousness, and its calming effect in the first psychiatric patient was immediate.
- Chlorpromazine treatment spread around the world between 1953 and 1955 and transformed disturbed wards.
- Deinstitutionalization without enough community services left many former patients homeless, a lesson for current mental health reform.
Milestones in the history of psychiatry
| When | Who or what | Why it matters |
|---|---|---|
| Early 1800s | Pinel and Tuke | Moral treatment: humane care; the model for the first public asylums |
| Late 1800s | Kraepelin | Psychoses classified by course: dementia praecox vs manic-depressive illness |
| 1911 | Bleuler | Renames dementia praecox schizophrenia |
| Mid-1900s | Psychoanalysis | Dominates psychiatry for about half a century and pushes classification aside |
| 1952 | Delay and Deniker; Laborit | Chlorpromazine enters psychiatry; later antipsychotics follow |
| 1955–1980 | Deinstitutionalization (United States) | State hospital population falls by more than three quarters; care moves to the community |
| 1959 | Imipramine | A tricyclic antidepressant, launched in the United States |
| 1980 | DSM-III | Explicit diagnostic criteria |
| 2013 | DSM-5 | The fifth edition of the DSM |

Think of the answer, then tap the question to see it.
What was moral treatment?
The humane care of people with mental illness promoted by Pinel and Tuke, which shaped the first public asylums in the early 1800s.
On what basis did Kraepelin separate dementia praecox from manic-depressive illness?
On their course: dementia praecox was progressive and deteriorating, while manic-depressive illness was episodic.
Who introduced chlorpromazine into psychiatry, and when?
Jean Delay and Pierre Deniker in Paris in 1952, after the surgeon Henri Laborit noticed that it calmed patients without loss of consciousness.
What did DSM-III (1980) change?
It introduced explicit diagnostic criteria for each disorder, modelled on the Feighner research criteria.
