Brain aneurysm
Brain Aneurysm
A Brain Aneurysm (pronounced: /brān/ /an-yə-riz-əm/), also known as a Cerebral Aneurysm or Intracranial Aneurysm, is a medical condition characterized by the bulging or ballooning in a blood vessel in the brain. The term "aneurysm" is derived from the Greek word "aneurysma," meaning "dilation."
Causes
Brain aneurysms are typically caused by a weakness in the walls of blood vessels in the brain. This weakness can be present at birth or develop over time due to high blood pressure or atherosclerosis (hardening of the arteries). Other factors that can contribute to the development of a brain aneurysm include head injury, high blood pressure, infection, tumors, and certain genetic disorders.
Symptoms
Symptoms of a brain aneurysm can vary depending on whether it has ruptured or not. Unruptured brain aneurysms often produce no symptoms and are typically discovered during tests for other conditions. When symptoms do occur, they can include pain above and behind the eye, dilated pupils, vision changes, and numbness or weakness on one side of the face.
A ruptured brain aneurysm is a medical emergency that can lead to a stroke, brain damage, or death. Symptoms can include a sudden, severe headache, nausea and vomiting, stiff neck, blurred or double vision, sensitivity to light, seizure, loss of consciousness, and confusion.
Treatment
Treatment for a brain aneurysm depends on the size, location, and whether it has ruptured. Options include observation, medical management, endovascular coiling, and neurosurgical clipping.
