In this article, we will discuss the Causes of Subarachnoid Hemorrhage. So, let’s get started.
Subarachnoid hemorrhage is defined as bleeding into subarachnoid space irrespective of its cause. The condition has a high mortality. It can be traumatic in origin or spontaneous (non-traumatic) caused by the rupture of a saccular aneurysm which is up to 5% in the normal population. Between 5 and 10% of stroke are due to subarachnoid hemorrhage.
