A bulging or ballooning in a blood vessel in the brain is known as a brain aneurysm. It resembles a fruit on a stem in appearance. A brain aneurysm can rupture or leak, resulting in brain haemorrhage (hemorrhagic stroke). The most common location for a ruptured brain aneurysm is the area between the brain and the thin tissues that cover it. A subarachnoid haemorrhage is a form of hemorrhagic stroke.
A ruptured aneurysm can soon become life-threatening, necessitating immediate medical attention. The majority of brain aneurysms, on the other hand, do not burst, cause health problems, or cause symptoms. Aneurysms of this type are frequently discovered during examinations for other disorders.
In some circumstances, treatment for an unruptured brain aneurysm is warranted and may prevent a rupture in the future. Consult your caregiver to make sure you’re aware of the best solutions for your individual needs.
1. Ruptured aneurysm
A ruptured aneurysm is characterised by a sudden, intense headache. This headache is frequently referred to as the “worst headache” ever.
The following are some of the most common signs and symptoms of a burst aneurysm:
• A strong headache that appears out of nowhere.
• Vomiting and nausea
• Neck stiffness
• Double vision or blurred eyesight
• Light sensitivity
• Search and seizure
• An eyelid that is drooping
• Consciousness loss
• Perplexity
2. ‘Leaking’ aneurysm
An aneurysm may occasionally leak a little amount of blood. This leaking (sentinel bleed) may only result in the following:
• A strong headache that appears out of nowhere.
Leaking is frequently followed by a more catastrophic rupture.
3. Unruptured aneurysm
If the aneurysm is tiny, an unruptured brain aneurysm may not cause any symptoms. A larger unruptured aneurysm, on the other hand, may strain on brain structures and neurons, potentially causing:
• Pain in the upper and lower eyelids of one eye
• A pupil that is dilated
• Double vision or a change in vision
• One side of the face is numb
Causes
A variety of events can cause artery wall weakening, increasing the risk of a brain aneurysm or aneurysm rupture. Adults are more likely than children to have a brain aneurysm, and women are more likely than males to have one. Some risk factors emerge over time, while others are present from birth. Factors that increase your risk over time. These are some of them:
• Getting older
• Smoking cigarettes
• Hypertension (high blood pressure)
• Substance abuse, notably cocaine use
• Excessive alcohol intake
Aneurysms can develop after a head injury (dissecting aneurysm) or as a result of certain blood illnesses (mycotic aneurysm).
