Moyamoya disease: a review.

Area of Science:

• Neurology
• Genetics
• Vascular Biology

Background:

• Moyamoya disease is a rare, inherited vasocclusive disorder with a global prevalence, initially identified in Japan.
• Understanding its pathogenesis is evolving, with potential variations across different racial groups.
• Current treatment strategies, particularly revascularization surgery, face ongoing debate regarding optimal timing and methods.

Purpose of the Study:

• To review recent advancements in the genetics and pathogenesis of Moyamoya disease.
• To discuss clinical manifestations and the role of surgical interventions.
• To highlight the need for broader research beyond East Asia.

Main Methods:

• Review of current literature on Moyamoya disease genetics and pathogenesis.
• Analysis of clinical presentations and surgical outcomes.
• Evaluation of advanced imaging techniques (fMRI, PET) and neuropsychological studies for assessing surgical efficacy.

Main Results:

• Genetic linkage studies and pathogenesis research are providing new insights into Moyamoya disease.
• Functional MRI and PET scanning offer objective criteria for evaluating surgical outcomes.
• Neuropsychological assessments can aid in judging the benefits of surgical interventions.

Conclusions:

• Continued research into Moyamoya disease genetics and pathogenesis is crucial for a comprehensive understanding.
• Objective assessment tools like fMRI and PET are vital for evaluating surgical success.
• Expanding research beyond Japan and the Korean peninsula is necessary to fully grasp the disease's global impact and variations.
