How did psychiatric neurosurgery evolve from ancient trepanation and controversial lobotomies to modern deep brain stimulation (DBS)?
In this fascinating presentation, Dr. Erik Blomstedt explores the complete history of psychosurgery, tracing its origins from prehistoric skull procedures through the rise and fall of lobotomy, the development of stereotactic neurosurgery, and today's cutting-edge DBS treatments for OCD, depression, and other psychiatric disorders.
Learn how changing medical knowledge, technological innovation, ethics, and neuroscience have shaped one of medicine's most controversial and intriguing fields.
Topics include:
• Trepanation and ancient theories of mental illness
• Early psychiatric brain surgery
• Moniz, Freeman, and the lobotomy era
• The psychosurgery debate
• Stereotactic neurosurgery
