What are the symptoms of cerebral aneurysms?
When the aneurysm is not ruptured, it produces no symptoms. Many aneurysms are discovered incidentally, when doing MRI scan for some other reasons. Rupture of the aneurysm causes various type of hemorrhage in the brain. They are • Subarachnoid hemorrhage (bleeding in between the outer covering layer of the brain) • Intracerebral hemorrhage (in to the brain substance itself) • Intraventricular hemorrhage occurs in 13-28 percent of the ruptured aneurysm cases. The prognosis appears to be worse for the patient in this category. • Subdural hemorrhage. The patient may have the following symptoms: • Weakness of limbs or cranial nerve palsies due to pressure effect by large aneurysms compressing the adjacent nervous tissue. • Visual loss. • Facial pain syndromes that may mimic trigeminal neuralgia. • Minor hemorrhage produces headache and neck pain. • Transient blindness in one eye. • Seizures. • Sudden severe headache, which is the worst headache in their life time due to sudden enlargement
