Abstract EN
To investigate white matter (WM) abnormalities in neocortical epilepsy, we extract supratentorial WM parameters from raw tensor magnetic resonance images (MRI) with automated region-of-interest (ROI) registrations.
Sixteen patients having neocortical seizures with secondarily generalised convulsions and 16 age-matched normal subjects were imaged with high-resolution and diffusion tensor MRIs.
Automated demarcation of supratentorial fibers was accomplished with personalized fiber-labeled atlases.
From the individual atlases, we observed significant elevation of mean diffusivity (MD) in fornix (cres)/stria terminalis (FX/ST) and sagittal stratum (SS) and a significant difference in fractional anisotropy (FA) among FX/ST, SS, posterior limb of the internal capsule (PLIC), and posterior thalamic radiation (PTR).
For patients with early-onset epilepsy, the diffusivities of the SS and the retrolenticular part of the internal capsule were significantly elevated, and the anisotropies of the FX/ST and SS were significantly decreased.
In the drug-resistant subgroup, the MDs of SS and PTR and the FAs of SS and PLIC were significantly different.
Onset age was positively correlated with increases in FAs of the genu of the corpus callosum.
Patients with neocortical seizures and secondary generalisation had microstructural anomalies in WM.
The changes in WM are relevant to early onset, progression, and severity of epilepsy.
