title: [Moyamoya disease in Taiwan].
abstract: From January 1978 to December 1993, 73 patients with moyamoya disease were collected from seven neurological centers in Taiwan. The annual incidence of this disease in Taiwan is 0.024 per 100,000 population. There were 33 males and 40 females. The ages ranged from 2 to 62 years with a peak incidence in the 31 to 40 year age group (18 cases). Cerebral infarction occurred in 16 out of 19 juvenile patients (84.2%); by contrast, only 19 out of 54 adult patients (35.2%) presented with infarction. Hemorrhagic strokes were more frequent in adult patients. Computed tomographic scans following stroke showed cerebral infarction in 35 cases, ventricular hemorrhage in 21 cases, intracerebral hemorrhage in 11 cases and pure subarachnoidal hemorrhage in 6 cases. The most frequent initial symptom was motor disturbance (58.9%), followed by headaches (49.3%), and impaired consciousness (34.2%). Compared with reports from Japan, this survey showed a lower incidence of moyamoya disease in Taiwan.
