Cerebral amyloid angiopathy (CAA) is a common cause of spontaneous intracerebral hemorrhage in older patients. Although other types of intracranial hemorrhage can occur in conjunction with CAA-related intracerebral hemorrhage, the association between CAA and other subtypes of intracranial hemorrhage, particularly in the absence of intracerebral hemorrhage, remains poorly understood.

脑淀粉样血管病和孤立性非创伤性硬膜下出血的风险。

脑淀粉样血管病（CAA）是老年患者自发性脑出血的常见原因。尽管其他类型的颅内出血可能与 CAA 相关的脑出血同时发生，但 CAA 与其他亚型颅内出血之间的关联，特别是在没有脑出血的情况下，仍知之甚少。
