The Role of White Matter in Focal Epilepsy

Epilepsy Res; 2018 Feb; Deleo et al.


 

Pathological changes in the brain’s white matter may contribute to focal epilepsy, suggests a recent review of the scientific research.

  • Investigators have uncovered pathological changes in white matter myelination, axonal integrity, and cellular composition among patients with epilepsy, based on ex vivo and postmortem studies.
  • Microstructural changes in several areas of the brain’s white matter near and at a distance from the epileptic focus have been discovered with the help of diffusion-weighted magnetic resonance imaging (MRI), including diffusion tensor imaging.
  • MRI of the brain’s white matter may also be helpful in predicting patients’ cognitive functioning and how they respond to drug and surgical treatment.
  • The literature review focuses on temporal lobe epilepsy and focal cortical dysplasia and the white matter anomalies detected in these disorders.
