AI Article Synopsis

  • The study aimed to describe the epidemiology and clinical features of Moyamoya disease in Nanjing, China, as prior documentation was lacking.
  • Researchers analyzed patient records from various hospitals over a period from 2000 to 2007, identifying 202 patients with varied age ranges and initial symptoms predominantly consisting of cerebral hemorrhage and ischemia.
  • Findings showcased a rising incidence of Moyamoya disease during the study years, with a notable bimodal age distribution, indicating it is more common in both young children (ages 5-9) and adults (ages 35-39).

Article Abstract

Objective: The epidemiology of Moyamoya disease in mainland China has not been documented. Therefore, the present study was designed to examine the epidemiological and clinical features of Moyamoya disease in Nanjing, a provincial capital in China.

Methods: Patient records from multiple hospitals in Nanjing from January 2000 to December 2007 were collected. The clinical features of Moyamoya disease were retrospectively analyzed.

Results: A total of 202 patients were identified. There were 94 males and 108 females, with ages ranging from 2 to 78 years. There was a dual age peak, one in the group of patients 5-9 years of age and another in the group of patients 35-39 years of age. The initial symptoms included cerebral ischemia (81 patients, 40%), cerebral hemorrhage (113 patients, 55.9%) and asymptomatic disease (8 patients, 3.9%). An increasing incidence rate of Moyamoya disease was observed during the period of 2000-2007, with an average detection rate of 0.43cases/100,000 persons/year (prevalence 3.92/100,000 persons). The incidence of ischemia associated with the disease was 0.16cases/100,000 people-years and the incidence of hemorrhage was 0.22cases/100,000 people-years.

Conclusion: This first study on the epidemiological and clinical features of Moyamoya disease in mainland China indicated an increasing incidence of Moyamoya disease with bimodal incidence distribution appearing more frequently in adults.

Chronic ischemia in moyamoya disease (MMD) impaired white matter microstructure and neural functional network. However, the coupling between cerebral blood flow (CBF) and functional connectivity and the association between structural and functional network are largely unknown. 38 MMD patients and 20 sex/age-matched healthy controls (HC) were included for T1-weighted imaging, arterial spin labeling imaging, resting-state functional MRI and diffusion tensor imaging.

Brush sign (BS) was first reported as prominent hypointensity of deep medullary veins and subependymal veins on T2*-weighted images at 3 T MRI in patients with acute stroke in the territory of the middle cerebral artery. Subsequently, BS in central nervous system (CNS) diseases such as moyamoya disease, cerebral venous thrombosis, and Sturge-Weber syndrome was also described on susceptibility-weighted imaging (SWI), and the clinical implications of BS were discussed. The purpose of this review is to demonstrate BS on SWI in various CNS diseases and its mechanisms in the above-mentioned diseases.

Objective: Periventricular anastomosis (PA), a recently recognized cause of hemorrhage in moyamoya disease, is reducible after bypass surgery. The timing of the reduction, however, remains poorly understood. The objectives of the present study were to demonstrate radiological reduction of PA occurring within 48 hours after surgery and to identify factors associated with reduction.
