Symptoms of an unruptured aneurysm are often minimal, but a ruptured aneurysm can cause severe headaches, nausea, vision impairment, and loss of consciousness, leading to a subarachnoid hemorrhage. Treatment options include surgical clipping and endovascular coiling, both aimed at preventing further bleeding.
Other common symptoms are a pulsing noise in the head, progressive weakness, numbness and vision changes as well as debilitating, excruciating pain. [4] [5] In serious cases, blood vessels rupture and cause bleeding within the brain (intracranial hemorrhage). [a] In more than half of patients with AVM, this is the first symptom. [7]
Atrial fibrillation causes blood clots to form within the heart, which may travel to the arteries within the brain and cause an embolism. The embolism prevents blood flow to the brain, which leads to a stroke. [26] An aneurysm is an abnormal bulging of small sections of arteries, which increases the risk of artery rupture.

Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen.
An aneurysm can occur in any blood vessel in the body, including the brain or heart. An aneurysm in the brain that ruptures is known as a hemorrhagic stroke, per the Mayo Clinic .
