A familial disorder with subcortical ischemic strokes, dementia, and leukoencephalopathy.
A family had a disorder characterized by (1) a pattern suggestive of autosomal dominant inheritance, (2) recurrent attacks of focal brain deficits starting in mid adulthood and often leading to severe motor disability with pseudobulbar palsy and dementia of the subcortical type, and (3) neuroimaging evidence of leukoencephalopathy and well-circumscribed lesions consistent with small deep infarcts. Some affected members were clinically asymptomatic but had MRI signs of leukoencephalopathy. Extensive investigations failed to uncover a previously described recognizable genetic disorder.
