Association Between Clinical Severity, Neuroimaging, and Electroencephalographic Findings in Children with Subacute Sclerosing Panencephalitis.

Early in the disease progression of subacute sclerosing panencephalitis, the temporoparietal and parietooccipital regions of the subcortical white matter are affected. Neuroimaging abnormalities exhibit a stronger association with Jabbour's clinical staging, but do not show significant associations with other clinical, sociodemographic, and EEG features.
