Understanding Moyamoya Disease
Moyamoya disease is a rare condition that affects the brain’s blood flow. It happens when the arteries at the brain’s base get too narrow. This makes tiny, weak blood vessels form, looking like “puff of smoke” on scans.
Definition and Symptoms
This disease is a type of brain blood vessel problem. It can make less blood flow to the brain. Early signs might be mini-strokes or “transient ischemic attacks” (TIA).
Other symptoms include weakness, trouble feeling things, or speaking problems. Kids might have their first stroke and show these signs too.
Causes and Risk Factors
We don’t fully know why moyamoya disease happens, but genes are thought to be a big part of it. It’s more common in people from Asia and usually starts in kids. It’s a type of stroke in young people.
Other risks include having a family history of brain blood vessel issues, certain genetic conditions, and other environmental factors. Knowing these risks helps find and treat it early.
- Genetic predisposition
- Geographical prevalence primarily in Asian populations
- Age, with common onset in childhood
- Family history of cerebrovascular disorders
