A brain aneurysm is an abnormal bulge in the wall of an artery in the brain. Find out how to detect them to avoid the damage they can cause.
According to the webpage MedlinePlus, most brain aneurysms do not show symptoms until they become large, leak blood or burst. It is therefore important to detect symptoms early to respond quickly and avoid complications.
According to the Brain Aneurysm Foundation, this condition can be detected if the following symptoms are present:
1) Unbearable headaches. This pain occurs because most aneurysms are located in the subarachnoid space, a small enclosed space just outside the brain. When the burst occurs, this space fills with blood. This rapid change in pressure is what causes this type of pain.
2) Nausea and vomiting. As this subarachnoid space fills with blood from a ruptured aneurysm, it begins to push on the brain towards a point called the foramen magnum. This puts pressure on the brain stem, a part of the brain that controls digestion and breathing; this causes dizziness, nausea and vomiting.
3) Blurry or double vision. Your vision can also become affected when an aneurysm begins to bleed or bursts. As the pressure increases on the brain stem, the protrusion or the control center of the eyes become affected. This can lead to blurry or double vision and light sensitivity.
4) Seizure. This may be a sign of a brain aneurysm that ruptures quickly. It occurs when the skull fills with blood and pressure is placed on it from more than one direction, putting all the neurons in danger.
