What is Cerebral Infarction Moyamoya Disease?
1. Moyamoya disease is an abnormal vascular network at the base of the brain, mainly involving the carotid siphon segment and the anterior and middle cerebral arteries, as well as chronic progressive stenosis or occlusion of the posterior cerebral arteries. Secondary abnormal small collateral vessel networks are characteristics of cerebrovascular diseases. Therefore, this disease cannot be called cerebral infarction. Cerebrovascular angiography reveals numerous dense small vessel shadows, resembling smoke, hence the name Moyamoya disease. The cause of this condition is related to genetics.
2. Clinically, cerebral infarction may occur, but more commonly, it presents as transient ischemic attacks, followed by epilepsy and hemorrhage. Moyamoya disease should not be regarded as cerebral infarction but as a distinct disease. Diagnosis is typically confirmed by cerebrovascular angiography. Treatment includes medical and surgical options. Medical treatment focuses on thrombosis management, increasing blood volume, dilating blood vessels, and improving blood supply. Surgical treatment involves bypass surgery.
Due to arterial pathology after cerebral infarction, the brain cells in the artery-dominated area undergo necrosis. Neurons are known to be non-regenerative, so many patients may suffer from certain sequelae, such as limited limb movement, limb numbness, unclear speech, and even some comprehension disorders. There is no need for excessive concern. With advancements in modern medicine, if cerebral infarction patients can reach the hospital promptly for effective intravenous thrombolysis or intra-arterial thrombectomy (both treatments require strict evaluation), some patients may have good prognoses and may even recover. The symptoms of most patients can significantly improve with treatment and rehabilitation. Although there may be some sequelae, they may not affect daily life. Cerebral infarction is likely to leave sequelae.
