Is subarachnoid hemorrhage hereditary?
Subarachnoid hemorrhage occurs due to the rupture of intracranial blood vessels and the subsequent leaking of blood into the subarachnoid space. In most cases, this condition is caused by the rupture of an aneurysm. This disease does not have a significant genetic predisposition, so there is no need for excessive worry. The common causes of this disease are primarily intracranial aneurysms, followed by vascular malformations. It should be noted that arteriosclerosis can also lead to the formation of aneurysms, and long-term smoking can also cause aneurysms. Subarachnoid hemorrhage often begins abruptly, and the patient might be engaged in some physical activity or experiencing fluctuating emotions when suddenly severe headache, nausea, vomiting, and even consciousness disturbances occur. It is essential to treat a subarachnoid hemorrhage as soon as possible.
