UNLABELLED Background and purpose Although cervicocranial artery dissections (CADs) are common causes of ischemic stroke in young individuals, anatomical locations and mechanisms of ischemic strokes are still unclear. We evaluate the prevalence, location, and pathogenic mechanisms of ischemic stroke caused by CADs. METHODS We reviewed CAD patients who(More)
We identified Charcot-Marie-Tooth disease type 1A (CMT1A) in a family with schwannomas in the spinal cord and median nerve. The CMT1A in this family showed an autosomal dominant pattern, like other CMT patients with PMP22 duplication, and the family also indicated a possible genetic predisposition to schwannomas by 'mother-to-son' transmission. CMT1A is(More)
Wake-up or unclear-onset strokes occur in up to one-fourth of patients with ischemic stroke. Although stroke severity and clinical outcomes appear to be poorer in wake-up strokes than nonwake-up strokes, many patients with wake-up strokes do not receive thrombolytic therapy because stroke onset time cannot be determined. Recent studies have suggested,(More)
Sleep disordered breathing (SDB) is an independent risk factor for cardiovascular disease. It is known to be associated more frequently with men than women, particularly in the premenopausal age range. The goal of this study is to evaluate gender differences among Korean patients diagnosed with SBD. This study included 309 patients who visited our Sleep(More)
The co-occurrence of multiple sclerosis and peripheral demyelinating neuropathy is rare. It has been disputed whether these are pathologically related or coincidental findings. We report a 36-year-old woman who presented with diplopia, right facial palsy and left-sided weakness. Brain magnetic resonance imaging showed a lesion indicative of central(More)
OBJECTIVES Endovascular procedures are one of the important treatment options for steno-occlusive arteries in ischemic stroke patients. However, embolic complications after such procedures are always a concern. The authors investigated the association between serial change of residual platelet reactivity and silent embolic cerebral infarction (SECI) after(More)
BACKGROUND To investigate whether ischemic lesion burden including lesion pattern, number, and volume would vary depending on risk stratification of aortic atheroma (AA). METHODS Acute stroke patients were enrolled if they had (1) acute ischemic lesions on diffusion-weighted imaging within 5 days of symptom onset, (2) cardioembolic stroke established(More)

Although cognitive decline in patients with extracranial ath-erosclerotic artery stenosis (ECAS) may be improved by carotid revascularization, 1 the effect of stenting on cognitive dysfunction in patients with intracranial(More)
