Why would someone need a lobotomy?

A lobotomy, a surgical procedure that involves severing connections in the brain's frontal lobe, was historically used to treat severe mental health conditions like schizophrenia, severe depression, and obsessive-compulsive disorder when other treatments failed. It aimed to alleviate extreme symptoms or behaviors that could not be managed by conventional therapies. However, due to significant ethical concerns and the availability of more effective and humane treatments, lobotomies are now considered obsolete and are rarely performed today.
