Subarachnoid hemorrhage in the elderly

Subarachnoid hemorrhage (SAH) refers to the general term of bleeding blood flowing into the subarachnoid cavity from various causes. Clinically, it can be divided into spontaneous and traumatic, and spontaneous can be divided into primary and secondary. The rupture of pial vessels caused by various reasons and the blood flowing into subarachnoid space are called primary subarachnoid hemorrhage; Secondary subarachnoid hemorrhage is called secondary subarachnoid hemorrhage when blood breaks through brain tissue and flows into subarachnoid cavity due to intracerebral hemorrhage. Generally, the so-called subarachnoid hemorrhage only refers to primary subarachnoid hemorrhage, accounting for about 15% of acute cerebrovascular diseases. The ones described in this section are also limited to this. The incidence rate of subarachnoid hemorrhage in elderly people is 21.6% to 39.5%, which is 10.5% to 20% higher than incidence rate in adults.
