What is psychosurgery/neurosurgery for mental disorders?
Brain surgery that promotes behavioural or affective changes in humans is controversial. 1935-1950 saw the use of “frontal lobotomies” to treat psychiatric disorders. This resulted in major personality changes. The surgery was often carried out by inadequately trained surgeons using a crude technique to blindly insert cutting instruments into the brain. There was a high incidence of complications and side effects.
Now-a-days, the technique is more refined, and the term “psychosurgery” has been replaced by the term “neurosurgery for mental disorders”.
