Diagnosis and Evaluation of Brain Aneurysm The diagnosis and evaluation of brain aneurysm are crucial for timely treatment and prevention of rupture. Doctors often find unruptured aneurysms by chance during brain scans. When symptoms do appear, they usually mimic other neurological problems. The diagnosis require a careful and structured approach involving both imaging and clinical assessment. 4 Common Methods of Diagnosis and Evaluation of Brain Aneurysm 1. Clinical signs and symptomsWhen an aneurysm ruptures, it causes a sudden, severe headache often described as the worst ever experienced. Other signs include nausea, vomiting, loss of consciousness, and neck stiffness. Unruptured aneurysms may cause headaches, blurred vision, or nerve pain. 2. Imaging techniques 3. Lumbar punctureIf a rupture is suspected but CT is negative, a spinal tap can detect blood in the cerebrospinal fluid — an important step in diagnosis. 4. Genetic testingIn cases where multiple family members are affected, or connective tissue disorders are suspected, genetic screening may be advised. In South Africa, the diagnosis are most accessible in urban centres. Delays may occur in rural settings due to lack of advanced imaging, making it essential for primary care providers to recognise warning signs and refer quickly. Diagnosis and Evaluation of Brain Aneurysm Accurate evaluation allow doctors to choose the safest treatment method — whether it be surgical, endovascular, or conservative management. 👉 [Next: Treatment Options for Brain Aneurysm]
