چکیده

BACKGROUND AND PURPOSE We conducted a prospective survey of a family presenting a new syndrome characterized mainly by recurrent strokelike episodes and neuroimaging evidence of leukoencephalopathy. SUMMARY OF REPORT Forty-five members of a single family were studied clinically and with magnetic resonance imaging. Nine had strokelike episodes, including transient ischemic attacks, and minor or major strokes starting between the fourth and sixth decades, with neuroimaging evidence of small, deep infarcts and a widespread white matter disorder. Other symptoms included migraine (three), dementia (two), epilepsy (one), and hearing loss (one). In some patients, we found various immunologic anomalies and muscular lipidosis without ragged-red fibers. Eight other family members were clinically normal, but had identical neuroimaging signs of leukoencephalopathy. No abnormality was detected in the 28 other members of the family examined. Extensive investigations failed to reveal any known cause of cerebral ischemia. CONCLUSIONS There appears to be a new syndrome in this family that is characterized by recurrent subcortical strokelike episodes, leukoencephalopathy, immunologic anomalies, muscular lipidosis, and an autosomal dominant pattern of transmission.

Diffusion-weighted MR imaging in a case of mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes.

In a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS), both T2- and diffusion-weighted MR imaging revealed lesions as hyperintense areas in the occipital lobes early after strokelike episodes. In these lesions, no significant reduction in apparent diffusion coefficient was noted. Apparent diffusion coefficient mapping may help to differentiat...

A Report of Accelerated Coronary Artery Disease Associated with Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common heritable form of vascular dementia and it is caused by mutations in the NOTCH3 gene. The neurologic manifestations of CADASIL syndrome have been well characterized; however, here we report one of the first de novo cases of CADASIL-associated coronary artery disease. A 45-year...

Cerebral blood flow in mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes.

BACKGROUND AND PURPOSE The precise mechanism of neurological symptoms with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS) is still controversial. We investigated the correlation between strokelike episodes and cerebral blood flow in two patients with MELAS and discuss the pathogenesis of strokelike episodes with MELAS. SUMMARY OF REPORT Cerebral dynam...
