A neurologist has issued an urgent warning about two critical signs that could indicate a potentially fatal brain aneurysm. Brain aneurysms occur when a blood vessel in the brain becomes enlarged, and if it bursts, it can lead to bleeding in the brain.
Dr Baibing Chen, known as Dr Bing, highlighted the first sign affecting the eyes: drooping of one eyelid, dilation of the pupil on that side, and difficulty moving the eye with blurry or double vision. This may indicate a large aneurysm compressing a cranial nerve.
The second sign is a thunderclap headache, described as reaching 10 out of 10 pain within seconds to a minute. Dr Chen warned this could signal that an aneurysm is in the early stages of rupturing.
Risk factors include family history, smoking, excessive alcohol consumption, and high blood pressure. The NHS advises calling 999 if you or someone else suddenly experiences these symptoms.
