What Is a Subarachnoid Hemorrhage?
3. Early Warning Signs
Aneurysms grow silently, and most people do not experience symptoms before they actually rupture. However, sometimes people are aware of changes as the aneurysm expands and presses on other parts of the brain. Small, preliminary leaks and emboli can also occur, resulting in minor symptoms.
The symptoms people notice in the hours or days before a brain aneurysm ruptures are usually minor sensory or motor disturbances such as drooping eyelids and difficulty speaking or understanding what other people say. Some experience seizures.
