| Research Abstract |
We performed diffusion tensor imaging (DTI) to assess white matter abnormalities in 23 patients with Cryptogenic West syndrome. DTI was acquired at 12 months and 24 months of age. Fractional anisotropy (FA) images in patients were compared with those of controls. DTI at 12 months of age in patients showed significantly decreased FA in widespread white matters. Radial diffusivity was increased in the skeleton. Developmental quotient (DQ) was positively correlated with FA. Patients with EEG abnormalities and seizures after treatments had lower FA than those of patients with normal EEG and seizure freedom at 12 months of age. DTI at 24 months of age did not show significant difference of FA between patients and controls. However, Patients with DQ lower than 70 showed decreased FA in widespread white matters. Laterality of PET abnormality and DTI abnormality was consistent. Decreased FA may represent delayed myelination and underlying pathology such as focal cortical dysplasia.
