Note.—The results reflect findings from each patient’s latest MR imaging study. The degree of myelin deficit, periventricular signal-intensity abnormalities, and atrophy were scored as follows: 0 = none, 1 = mild, 2 = severe. PO = parieto-occipital, FP = frontoparietal.
* Corpus callosum involved.
† Patchy white matter lesions.
