Mental health refers to a person's ability to feel, think, and act in ways that improve their quality of life. Mental disorders, on the other hand, are health conditions that affect cognitive functioning, emotional responses, and behavior.
One of the most controversial methods for curing mental disorders was lobotomy. It was a type of psychosurgery used to treat mental illnesses, including anxiety. It involved brain connections being severed. Sometimes the treatment leaves the patients permanently incapacitated, but their uneasiness and worry are gone as well, with all their feelings and memories washed away.
