History of psychiatry: Was psychorsurgery a sensible move during difficult times or a fatal mistake?

Address the question of whether Leucotomies were sensible at the time (as argued by Jack Pressman in his book ‘Last reaort’) or a fatal mistake as argued by many critics since the 1940s. Focus mainly Pressman’s arguments in his book ‘Last Resort’. Discuss psychiatry at the time, the benefits and side effects/outcomes of leucotomies.
