Area of Science:

  • Neuroimaging
  • Pediatric Neurology
  • Epileptology

Background:

  • Epilepsy in preschool children presents unique diagnostic and management challenges.
  • Understanding the neurobiological underpinnings of early-onset epilepsy is crucial.

Purpose of the Study:

  • To investigate structural brain abnormalities in preschool children with MRI-negative epilepsy.
  • To compare cortical and subcortical brain structures between children with epilepsy and healthy controls.

Main Methods:

  • Utilized Freesurfer software for quantitative analysis of brain structures.
  • Measured cortical thickness, curvature, surface area, volume, and subcortical volumes.
  • Included preschool children with epilepsy and age-matched controls.

Main Results:

  • Observed cortical thickening in specific gyri (fusiform, middle temporal) and sulci (suborbital, gyrus rectus).
  • Detected cortical thinning predominantly in the parietal lobe, with significant findings in the superior parietal lobule.
  • Found alterations in cortical mean curvature, surface area, and volume in frontal and temporal lobes, with correlations to epilepsy characteristics.

Conclusions:

  • Epilepsy in preschool children is associated with cortical, not subcortical, structural alterations.
  • These findings contribute to understanding epilepsy's impact on developing brains.
  • Informs clinical management strategies for pediatric epilepsy.
