What is Moyamoya Disease?
The disease called “moyamoya” gets its name because the tangled brain blood vessels resemble smoke. These vessels attempt to increase blood flow but are fragile, increasing the risk of strokes.
Historical Context
Moyamoya disease was first identified in Japan during the 1960s, named for its “smoke-like” blood vessels. Today, it is recognized globally, particularly in East Asia. Advances in research have improved our understanding and management of the condition.
Understanding moyamoya disease enables both doctors and patients to manage it effectively.
| Aspect | Details |
|---|---|
| Origin | Japan, 1960s |
| Prevalence | Higher in East Asian populations |
| Major Risks | Ischemic and hemorrhagic strokes |
| Key Features | Narrowing of cerebral arteries, “puff of smoke” appearance |
Signs and Symptoms of Moyamoya Disease
Moyamoya disease presents various symptoms that impact daily life. The initial sign often is a transient ischemic attack (TIA), or “mini-stroke,” which occurs when blood flow to the brain temporarily halts, leading to brief neurological symptoms.
Strokes are more severe and longer-lasting than TIAs, often causing neurological issues such as unilateral weakness, vision disturbances, and speech difficulties. Seizures may also occur due to inadequate blood flow to the brain.
Individuals with moyamoya often experience cognitive issues, such as difficulty concentrating, memory lapses, or challenges in learning. Children may also face delayed developmental milestones.
Symptoms such as headaches and tremors can complicate managing moyamoya disease. Early detection and regular monitoring are essential for effective care.
