Signs of a brain aneurysm

My nephew just underwent emergency surgery due to a ruptured brain aneurysm causing hemorrhage. How can we recognize and screen for this condition early? (Tri Hung, Tay Ninh )

Aneurysms can occur in anyone. Most cases of cerebral aneurysms or vascular malformations are asymptomatic, with no specific symptoms. Some easily mistaken symptoms may include headaches, dizziness, and difficulty sleeping.

A large aneurysm can rupture, causing subarachnoid hemorrhage or bleeding in the brain. At this point, patients often experience symptoms such as sudden, unusual, and worsening headaches, nausea, vomiting, stiff neck, impaired consciousness, weakness or paralysis of the limbs, and coma. Patients need to be taken to a medical facility with the necessary diagnostic and treatment capabilities for prompt intervention.

Although the signs of cerebral aneurysms are difficult to recognize, they can be proactively screened and detected using modern techniques. 3D magnetic resonance angiography (MRI) helps detect aneurysms or vascular malformations in the brain.

Digital subtraction angiography (DSA) helps to identify small aneurysms. Doctors use the results of MRI or DSA (digital subtraction angiography) and related scoring systems to determine the condition, severity, and appropriate treatment plan.

Common treatments for aneurysms include endovascular embolization, surgical clipping, aneurysm removal, or medical treatment with continued monitoring.

A ruptured cerebral aneurysm can cause hemorrhagic stroke. Regular stroke screening is an effective way to detect and diagnose abnormalities. Doctors conduct a general clinical examination and combine it with specialized tests and imaging such as blood tests, carotid artery ultrasound, electrocardiogram, kidney and liver function tests, MRI, and CT scans of the brain.

More in-depth tests such as genetic screening, multifocal atherosclerosis testing, and blood clotting risk assessment are applied depending on the case.
