資料篩選標準─診斷

以診斷進行篩選：

1.診斷：採用PubMed，採較廣義的定義，概化較廣

Cerebrovascular Disorders

A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES; or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.

Intracranial hemorrhage

2.將有dementia、schizophrenia、Parkinson's disease、aphasia等特殊疾病的病人標記但暫不刪除

3.排除：Cerebral Palsy、Traumatic brain injury、Brain tumor(cancer)、Meningitis、Meningioma、brain abscess、Acoustic neuroma

疑問：
1.部分只寫 Intracranial hemorrhage、 Intracerebral hemorrhage或 Cerebral hemorrhage 的是否一定是中風？可能需要進一步查詢釐清是否為其他原因(如車禍、跌倒等)造成？
2.AVM是否排除？
