Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Summary
This summary is machine-generated.

Stereotactic psychosurgery using radiofrequency (RF) or CyberKnife radiosurgery (CKRS) offers a safe and effective treatment for severe mental illnesses. This minimally invasive approach significantly improved symptoms in patients with aggressive behavior, obsessive-compulsive disorder, and depression.

Area of Science:

  • Neurosurgery
  • Psychiatry
  • Medical Technology

Background:

  • Medically intractable mental illnesses pose significant challenges to treatment.
  • Stereotactic psychosurgery offers a potential therapeutic option for severe psychiatric conditions.
  • Advancements in lesioning techniques include radiofrequency (RF) and CyberKnife Radiosurgery (CKRS).

Purpose of the Study:

  • To evaluate the safety and efficacy of stereotactic psychosurgery for medically intractable mental illnesses.
  • To assess the outcomes of RF and CKRS lesioning in patients with aggressive behavior, OCD, and depression.
  • To report on the long-term follow-up results of these procedures.

Main Methods:

  • Thirty-eight patients with severe mental illnesses underwent stereotactic psychosurgery between 1993 and present.
  • Procedures included bilateral amygdalotomy, subcaudate tractotomy, limbic leucotomy, anterior cingulotomy, or combinations thereof.
  • Lesions were created using either radiofrequency (RF) generators (23 patients) or CyberKnife Radiosurgery (CKRS) (15 patients).

Main Results:

  • Significant clinical improvement was observed, with the Overt Aggression Scale (OAS) declining from 8 to 2.
  • In Obsessive-Compulsive Disorder (OCD) patients (n=25), the Yale Brown Obsessive Compulsive Score (YBOCS) decreased from 34 to 13 over a mean follow-up of 57 months.
  • For depression patients (n=10), the Hamilton Depression Scale (HAMD) scores reduced from 38.5 to 10.5, with no operative mortality and minimal morbidity.

Conclusions:

  • Stereotactic psychosurgery utilizing RF and CKRS demonstrates safety and efficacy in treating specific medically intractable mental disorders.
  • These advanced lesioning techniques provide a viable treatment alternative for patients who have not responded to conventional therapies.
  • The study supports the continued use of stereotactic psychosurgery as a therapeutic option in severe psychiatric cases.
