According to some resources incidence of occurring LS is 1 in 40,000 new born and unusually in adult hood. Characteristics lesion in basal ganglia associated with demyelination. Primary feature includes: subacute relapsing encephalopathy with cerebral and brain-stem signs presenting during infancy. Additional feature includes: basal ganglia lucencies.
