What are we really predicting with fMRI in epilepsy surgery?

Area of Science:

• Neuroimaging
• Epilepsy Surgery
• Neuropsychology

Background:

• Current functional magnetic resonance imaging (fMRI) paradigms for epilepsy surgery are sophisticated.
• Outcome measures often rely on outdated neuropsychological tests with limited real-world relevance.
• A disconnect exists between advanced predictive methods and traditional outcome assessments in epilepsy surgery literature.

Purpose of the Study:

• To address the imbalance between advanced fMRI techniques and traditional outcome measures in epilepsy surgery.
• To examine core principles of neuropsychological outcome assessment in epilepsy surgery.
• To propose adaptations for fMRI study designs to enhance clinical relevance.

Main Methods:

• Review of current practices in neuropsychological outcome assessment for epilepsy surgery.
• Analysis of the limitations of traditional pencil-and-paper tests.
• Exploration of principles for adapting assessments within fMRI study designs.

Main Results:

• Traditional neuropsychological tests show poor correlation with patients' real-world experiences.
• Sophistication of predictive fMRI paradigms is outpacing the relevance of outcome measures.
• There is a need for updated outcome assessment strategies in fMRI epilepsy research.

Conclusions:

• Adapting neuropsychological assessments is crucial for improving the clinical utility of fMRI in epilepsy surgery.
• Future fMRI studies should integrate more relevant and sensitive outcome measures.
• Enhancing outcome measures will strengthen the link between fMRI research and patient-centered care in epilepsy surgery.
