By the 1950s, studies revealed that there was a fatality rate of 1.5 to 6 percent caused by lobotomies.
A lobotomy, also known as a leucotomy, is a type of neurosurgical treatment for mental or neurological disorders that involves destroying connections in the prefrontal cortex of the brain.
The goal of a lobotomy is to relieve stress or agitation, and many early patients showed these results. However, many people experienced indifference, laziness, lack of initiative, poor concentration, and a general decline in the depth and intensity of their emotional response to life. Electroshock would render a patient comatose, as people who witnessed the treatment described it. Freeman would then put a sharp ice pick-like tool above the patient's eyeball, into the orbit of the eye, and into the frontal lobes of the brain, back and forth.
