Brain Aneurysm Warning Signs and Symptoms
Call 9-9-5 immediately if you or a loved one is experiencing brain aneurysm symptoms. Not all symptoms may be present simultaneously but the below are the most common.

What Are the Warning Signs of a Brain Aneurysm?
When a brain aneurysm ruptures or bursts, it can lead to a type of stroke. A hemorrhagic stroke also occurs when a weak blood vessel ruptures inside the brain and bleeds. A subarachnoid hemorrhage is a type of hemorrhagic stroke. The difference is that this kind of stroke is when the surface of the brain bleeds. A subarachnoid hemorrhage threatening condition and medical emergency can cause permanent damage and time is of the essence.
