Early Symptoms of Brain Aneurysms, Brain Aneurysm Warning Signs

Doctors at NewYork-Presbyterian Hospital say that brain aneurysms usually won't show signs or symptoms before they hemorrhage.

Sometimes, though, an aneurysm may press on surround brain structures, causing:

Headache
Numbness
Pain behind the eye
Vision change
Weakness

Doctors can determine if these symptoms and warning signs are related to a cerebral aneurysm, often by using imaging tests such as CT and MRI scans. Brain angiograms may also be used for treatment planning.

Some unruptured aneurysms, especially small ones, may not need treatment. Doctors assess these patients regularly with imaging studies to make sure the aneurysm is not growing.

In other cases, doctors may decide that an aneurysm must be repaired with surgical clipping or endovascular coiling to prevent a stroke. When an aneurysm of any size ruptures, it is a medical emergency.

Along with treating brain aneurysm, NewYork-Presbyterian is also a leader in cerebral aneurysm research.

If you are experiencing symptoms of an aneurysm, call 911 and seek emergency attention immediately.
