Psychosurgery – treats psychological disorders through surgery

Psychosurgery is a medical technique that can be used to treat the symptoms of psychological disorders. The technique is the most invasive of all the biological therapies and is also the least used because its effects are irreversible. For many centuries a crude psychosurgical technique called trepanning was used to try and help patients suffering from mental illnesses such as schizophrenia. Trepanning involved making a hole in a person’s skull in order to release the evil spirits that were considered to be causing the mental illness. Naturally this practice was very dangerous and often caused the death of the people undergoing the procedure.
