Pathophysiology of Vascular Stenosis and Remodeling in Moyamoya Disease

Frontiers in Neurology, 2021
Moyamoya disease (MMD) and moyamoya syndrome (MMS) are progressive vascular pathologies unique to the cerebrovasculature that are important causes of stroke in both children and adults.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

The Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

Extremely Rare Breakdown of the Moyamoya Vessels Resulting in Intraventricular Hemorrhage after Direct Bypass Surgery in a Pediatric Patient with Moyamoya Disease

, 2020
Revascularization surgery is established for both ischemic and hemorrhagic moyamoya disease (MMD), although hemorrhagic complication is a serious problem especially in adult MMD patients showing postoperative hyperperfusion.

Mood disorder in association with moyamoya disease

, 2012
MOYAMOYA DISEASE IS an inherited vaso-occlusive disease in which dilated collateral vessels appear hazy on angiography.1 Neuropsychiatric manifestations associated with moyamoya disease are uncommon.2 We describe a case of a 16-year-old boy with atypical

Calibration‐Free Estimation of Cerebrovascular Reactivity From Resting‐State BOLD fMRI Using Reconstructed Respiratory Fluctuations

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2755-2766, December 2026.
ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).

Mutation genotypes of RNF213 gene from moyamoya patients in Taiwan

, 2017
Moyamoya disease (MMD) is a disorder characterized by stenosis of bilateral internal carotid arteries with compensatory angiogenesis of the perforating blood vessels. Familial transmission in MMD is common.

Whole‐Brain 4D MRA With Improved Vessel Delineation Using Undersampled Multiple Overlapping Thin‐Slab Radial Acquisition

NMR in Biomedicine, Volume 39, Issue 12, December 2026.
A noncontrast‐enhanced 4D MRA technique by integrating pulsed ASL with undersampled multiple overlapping thin‐slab stack‐of‐stars golden‐angle radial acquisition is developed for the evaluation of whole‐brain arterial flow dynamics with improved vessel delineation. The proposed method substantially reduced RF saturation effects and preserved signals in

Moyamoya disease and moyamoya syndrome

Aktualności Neurologiczne
Moyamoya disease is a rare, progressive cerebrovascular disorder caused by narrowed or blocked arteries supplying the brain. The name refers to the appearance of net-like collateral blood vessels that develop in response. Its incidence is significantly higher in East Asian countries and primarily affects children in the first decade of life, although ...

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, Volume 200, Issue 11, Page 2568-2574, November 2026.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.
