Psychosurgery

98
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.

Summary

Resective surgery is the primary surgical treatment for temporal lobe epilepsy (TLE), offering effective seizure control. Alternative therapies like radiosurgery and laser interstitial thermal therapy (LITT) provide options for specific patient groups.

Area of Science:

  • Neurosurgery
  • Epileptology
  • Medical Technology

Background:

  • Temporal lobe epilepsy (TLE) is the most common refractory epilepsy.
  • Surgical intervention is a key strategy for seizure control in TLE.
  • Existing surgical options include resective surgery, stereotactic radiosurgery, and laser interstitial thermal therapy (LITT).

Purpose of the Study:

  • To review current surgical treatments for temporal lobe epilepsy.
  • To compare the efficacy and safety of various surgical modalities.
  • To establish resective surgery as the reference standard for TLE treatment.

Main Methods:

  • Review of existing literature on surgical treatments for TLE.
  • Comparison of outcomes (seizure control, safety, cognitive function, cost) for different surgical techniques.
  • Evaluation of emerging therapies such as LITT and brain-responsive stimulation.

Main Results:

  • Resective surgery achieves a ~70% seizure-free rate in mesial and neocortical TLE.
  • Resective surgery offers superior seizure outcomes compared to stereotactic radiosurgery for mesial TLE.
  • Stereotactic radiosurgery and resective surgery show similar safety, cognitive, and cost profiles.
  • LITT shows promise for mesial TLE, requiring further evaluation.
  • Brain-responsive stimulation is a palliative option for specific TLE cases.

Conclusions:

  • Resective surgery remains the first-line surgical treatment for TLE.
  • Stereotactic radiosurgery is a viable alternative for patients unsuitable for open surgery.
  • LITT and future ultrasound therapies warrant further investigation.
  • A range of surgical options exist, tailored to individual patient needs and TLE subtypes.
