Meaning and Definition
A surgical operation in which nerve fibres in the brain are severed, historically used as a treatment for severe mental illness.
Historically, a psychosurgical procedure (specifically a prefrontal leukotomy) involving the cutting of white matter nerve tracts connecting the prefrontal cortex to other brain areas, intended to alleviate symptoms of mental disorders but often resulting in severe personality changes and cognitive deficits. The term is now primarily historical.

FAQ
Frequently Asked Questions
They are closely related. Lobotomy is a broader term for psychosurgery involving the brain's lobes. Leukotomy specifically refers to cutting the white matter tracts (leuko = white), often within a lobotomy procedure, like the prefrontal leukotomy.

It is associated with a period of crude, often non-consensual, and damaging psychiatric surgery that left many patients with severe, irreversible personality and cognitive deficits, leading to widespread ethical condemnation.
The development of effective antipsychotic medications (neuroleptics) in the 1950s, along with advances in psychotherapy and a greater emphasis on patient rights and ethical oversight, led to the abandonment of leukotomy.
