Lobotomy

Historical, now abandonedImportant in its time, no longer accepted.
Brain surgery that cut connections to the frontal lobes to calm psychiatric patients, popular from 1935 into the 1950s.

Portuguese neurologist Egas Moniz performed the first 'leucotomy' in 1935 and won the 1949 Nobel Prize. In the US, Walter Freeman devised a quick 'ice-pick' version through the eye socket and performed about 3,400 himself. Roughly 40,000 to 50,000 Americans were lobotomized, including Rosemary Kennedy in 1941. Patients often became calmer but apathetic, childlike or impaired, and some died. The Soviet Union banned it in 1950; antipsychotic drugs ended it in the West.
Why it matters
It is psychiatry's cautionary tale: enthusiasm, a Nobel Prize and desperately overcrowded hospitals outran the evidence, causing lasting harm to patients.
The evidence
Surgical records, Freeman's case files, follow-up reports, and historians such as Elliot Valenstein and Jack Pressman who reconstructed its rise and fall.
Open questions
Historians debate how much it was cynical control versus a sincere, if badly tested, attempt to help patients who had no other options.
Connections (2)
▸Lobotomy severed connections to Prefrontal cortex: planning and self-controlWell replicated
The connection
Surgeons cut or scraped the white-matter fibers linking the prefrontal cortex to deeper brain regions, on the theory that fixed, abnormal circuits caused mental illness. Severing them often reduced agitation but also damaged planning, initiative and emotional depth, the very functions the prefrontal cortex supports.
Who showed it and when
Lisbon, 1935 (Moniz and surgeon Pedro Almeida Lima); Washington, D.C., from 1936 (Walter Freeman and James Watts); Freeman's eye-socket method from 1946.
The evidence
Surgical descriptions, autopsies and follow-up studies documented both the cut fibers and the resulting blunting of judgment and motivation.
Open questions
Why some patients seemed to benefit while others were devastated is unclear, because early results were rarely compared with untreated patients.
▸Lobotomy was replaced by Antipsychotic medicationsWell replicated
The connection
Lobotomy spread because overcrowded hospitals had few tools to calm severely ill patients. Chlorpromazine offered a far safer, reversible way to reduce agitation and psychosis. Within a few years of its arrival lobotomies fell sharply, and by the 1960s the operation was rare.
Who showed it and when
Chlorpromazine reached the US in 1954; Walter Freeman, lobotomy's leading promoter, kept operating until 1967.
The evidence
Hospital and surgical records show lobotomy numbers dropping in the mid-1950s as Thorazine use rose; historians such as Jack Pressman document the shift.
Open questions
Lobotomy was already drawing medical criticism before 1954, so historians debate how much drugs caused its decline versus speeding one already under way.
