Current challenges in the practice of epilepsy surgery

Area of Science:

• Neurology
• Neurosurgery
• Developmental Psychology

Background:

• Accurate prediction of individual outcomes after epilepsy surgery is a significant clinical challenge.
• Maximizing medical, psychosocial, cognitive, and psychiatric outcomes necessitates precise surgical candidacy and timing.
• A lifespan approach considering epilepsy's impact on development is crucial for predicting postsurgical risk and resilience.

Purpose of the Study:

• To promote a differentiated understanding of postsurgical risk and resilience by considering an individual's developmental trajectory.
• To enhance the definition of surgical candidacy and outcome prediction through emerging research areas.
• To emphasize comprehensive, longitudinal outcome assessment and the development of a broader outcome classification system.

Main Methods:

• Adopting a lifespan perspective to view epilepsy surgery as a developmental turning point.
• Utilizing cortico-cortical evoked potentials to map seizure propagation pathways and functional networks.
• Developing predictive models for postoperative depression incorporating psychosocial and neurobiological factors.

Main Results:

• A lifespan approach aids in understanding patient/family expectations and the interplay of factors influencing outcomes.
• Cortico-cortical evoked potentials can identify seizure pathways and functional networks.
• A model integrating psychosocial and neurobiological factors shows promise in predicting postoperative depression.

Conclusions:

• A developmental, lifespan approach is key to personalized epilepsy surgery candidacy and outcome prediction.
• Emerging research in neurophysiology and psychosocial factors offers new avenues for predicting surgical success.
• Routine follow-up and psychosocial rehabilitation are vital, especially for high-risk patients, necessitating further research into re-surgery criteria.
