An arteriovenous malformation (AVM) is a defect between the arteries and veins, which affect the connection between these blood vessels, disrupting the flow of blood between them. While an arteriovenous malformation can occur anywhere, AVMs are most common in the brain or spine.
A brain aneurysm is a protruding, weak area in the wall of an artery that supplies blood to the brain. Most often, a brain aneurysm will cause no symptoms and go unnoticed. In some cases, the brain aneurysm ruptures, releasing blood into the skull, causing a stroke.
A brain tumor is a mass or growth of abnormal cells within the brain. There are various types of brain tumors, some of which are noncancerous (benign), and others which are cancerous (malignant). Symptoms associated with a brain tumor include headaches, seizures, sensory and motor loss, vision loss, fatigue, depression, hormone/gland changes, and behavioral changes.
The term movement disorders refers to a group of neurological conditions that cause abnormal voluntary or involuntary movement, or reduced movement. While some movement disorders are temporary, others, such as Parkinson's disease, are progressive and serious.
A stroke is caused by a blocked blood vessel or bleeding in the brain. Signs of stroke include sudden severe headache, confusion, vision problems, weakness, dizziness, and slurred speech. Diseases associated with strokes include diabetes, high blood pressure, high cholesterol, heart disease, obesity, connective tissue disorders, or family history of strokes. If you have symptoms of a stroke, call 9-1-1 immediately.
Traumatic Brain Injury
Traumatic brain injury occurs when an external force causes brain dysfunction. This is usually a result from a forceful blow or jolt to the head or body. Mild traumatic brain injury may cause temporary dysfunction of brain cells, while more serious brain injury can result in long-term complications or potentially death.
