Moyamoya disease causes blood vessels (one or both carotid arteries, as well as the cerebral arteries in some cases) in the brain to narrow, thereby obstructing the flow of blood. Narrowed arteries greatly increase one’s risk of stroke, as well as transient ischemic attacks, also known as mini strokes.
As a progressive condition, moyamoya disease must be properly managed to prevent life-threatening complications from occurring. Along with other treatments, many people with this rare condition benefit from medication.
People with moyamoya disease are at risk of serious health effects, such as seizures, headaches, and transient ischemic attacks. To reduce the chances of these effects occurring, doctors may prescribe the following medications:
These medications are used to lower the chance of harmful clots forming, while also reducing damage to the blood vessels.
People with moyamoya disease experience a better outcome when effects are managed early. In this case, your doctor may discuss a revascularization procedure. This surgery involves rerouting blood vessels located on the outside of the skull to boost the flow of blood to the brain, which bypasses obstructed arteries.
Moyamoya disease can also cause cognitive changes as the blood vessels become narrowed. Monitoring changes is important for determining whether another type of treatment is needed. Because the condition can take a toll on one’s mental health, therapy and psychological support may also be recommended.
