Brain aneurysms are balloon-like bulges in the brain’s blood vessels that often cause no warning signs until they press on nerves or rupture, leading to severe bleeding. Early symptoms can include sudden, intense headache, vision changes, pain above the eye, drooping eyelid and facial weakness — all requiring prompt medical care. Treatments range from minimally invasive endovascular coiling to surgical clipping to prevent rupture and manage complications. With expert care from Dr Arvind Nanda, timely diagnosis and advanced interventions help improve outcomes and support long-term brain health
