Is Moyamoya A Serious Disease?
Moyamoya disease is a serious disease leading to either impermanent or lasting brain injury . It is an passing rare experimental condition , wherein the carotid artery in the skull , fundamentally the base of the brain called the basal area ; encounters constrict or thinning of the vessels lead to decreased parentage flow to the brain . It is sort as a type of reformist lineage vessel ( vascular ) upset . The chemical group of meek tiny origin vessels appears like a cluster , hence , the word “ moyamoya ” meaning “ puff of hummer ” in Japanese . These vessels are not sufficiently outfit to transfer the ask oxygen and profligate to the genius , resulting in brain injury . In medical language , it is a extremely progressive , occlusive disease of the cerebral vasculature with particular involvement of the circle of Willis and the arteries that bung it.(1 )
The Moyamoya condition is known to affect the younger eld group , mainly children ; but adult may too spring up it . It is highly predominant in East Asian Countries , specially Korea and China .
The disease is can result in multiple issue like , aneurism of vessels ( bulging / haemorrhage in the blood vessel ) ; acute stroke or transient ischemic attempt ; cognitive / memory stultification ; delay developmental milestone ; etc . Most significantly , if , a major quadrant of the vessels is affect , it can pass to permanent disability for the patient role .
Moyamoya Symptoms
The primary symptom of Moyamoya Disease ’s presentation is perennial transitory ischemic attacks / stroke ( even mini - stroke ) ; specially in children . Basically all signs and symptoms in Moyamoya disease are a aftermath of abnormal / reduced origin flow in the vessel :
These symptom can be further aggravated by any strenuous activity or stress . Henceforth , care must be fulfill especially in case of children ; as there are chances of accenting of symptoms while crying.(2 )
Predisposing Risk Factors For Moyamoya
Significant Family History . In case , even 1 family member is affected with the disease ; it is a must to get all members of the syndicate genetically screened ; especially unseasoned children .

The Acquired causes admit primarily stern header trauma or accidental head injury .
Geographical Distribution . The disease is known to bear upon Asians more as in comparison to any other zone ; especially Japan and Korea . The genetic correlation regarding the same is still under discussion .
Demographics . Moyamoya disease is love to affect youthful children especially below the age of 12 - 15 years . The reason though is unknown , but the disease is more prevalent in Female gender .
As described earlier , it is a reform-minded disease and must be stop with the assist of handling or surgical process .
