Psychosurgery was developed early in human prehistory (trephination) as a need perhaps to alter aberrant behavior and treat mental illness. The "American Crowbar Case" provided an impetus to study the brain and human behavior. The frontal lobe syndrome was avidly studied. Frontal lobotomy was developed in the 1930s for the treatment of mental illness and to solve the pressing problem of overcrowding in mental institutions in an era when no other forms of effective treatment were available. Lobotomy popularized by Dr. Walter Freeman reached a zenith in the 1940s, only to come into disrepute in the late 1950s. Other forms of therapy were needed and psychosurgery evolved into stereotactic functional neurosurgery. A history of these developments up to the 21st century will be related in this three-part essay-editorial, exclusively researched and written for the readers of Surgical Neurology International (SNI).
