Cerebral aneurysm

Cerebral aneurysm

Overview

Weakness, numbness, or other loss of nerve function may indicate that an aneurysm may be causing pressure on adjacent brain tissue. Symptoms such as a severe headache, nausea, vomiting, vision changes or other neurological changes can indicate the aneurysm has ruptured and is bleeding into the brain. A ruptured intracranial aneurysm causes intracranial bleeding and is considered very dangerous.
