What are the symptoms of congenital cerebral aneurysm?

Symptoms of congenital cerebral aneurysm include headache, nausea and vomiting, impaired consciousness, epilepsy, etc. If this happens, it is best to go to the hospital in time to find out the cause.

Brain aneurysm refers to a tumor protruding from the arterial wall caused by the localized abnormal expansion of the lumen of the cerebral artery. It is mainly caused by local congenital defects in the cerebral arterial wall and cystic swelling caused by increased cavity pressure. It is the first cause of subarachnoid hemorrhage. Its typical manifestations are the symptoms and signs of subarachnoid hemorrhage caused by aneurysm rupture and bleeding. It often manifests as nausea and headache, but it can also damage the optic nerve and have a certain impact on vision.

Common symptoms of brain aneurysms include

1 Headache: For most patients, sudden splitting pain can extend to the neck, shoulders, back and lower limbs.

2Nausea, vomiting, pale complexion, and cold sweats.

3. Consciousness disorder: More than half of the patients may be briefly confused or even in a deep coma. A small number of patients may not have consciousness changes, but they may have symptoms such as photophobia, apathy, fear of noise and vibration.

4 Psychiatric symptoms: manifested as delusions, rigidity, disorientation, confabulation and dementia.

5 Epilepsy: 20%0% of patients, mostly suffer from major seizures.

6 signs: ① Meningeal irritation symptoms may occur within a few hours to 6 days, but 1 to 2 days is the most common. ② Pyramidal tract symptoms may occur unilaterally or bilaterally.

③ Fundus hemorrhage may be retinal, vitreous membrane or intravitreal hemorrhage. It is common in ruptured anterior communicating artery aneurysms, which cause central retinal vein hemorrhage due to increased intracranial pressure and blood clots compressing the optic nerve sheath. This is of special significance because it still exists after the cerebrospinal fluid returns to normal, which is one of the important bases for diagnosing subarachnoid hemorrhage and an important cause of blindness in patients.
