    Brain Diseases: Vascular (Blood Vessels) Conditions

    Brain diseases connected with blood vessel conditions include:

    Stroke: Blood flow and oxygen are suddenly interrupted to an area of brain tissue, which then may die. The body part controlled by the damaged brain area (such as an arm or a leg) may no longer function properly.

    Ischemic stroke: A blood clot suddenly develops in an artery or is formed elsewhere in another artery and breaks off and lodges in the brain blood vessels, blocking blood flow and causing a stroke.

    Hemorrhagic stroke: Bleeding in the brain creates congestion and pressure on brain tissue, impairing healthy blood flow and causing a stroke.

    Cerebrovascular accident (CVA): Another name for stroke.

    Transient ischemic attack (TIA): A temporary interruption of blood flow and oxygen to a part of the brain; symptoms are similar to those of a stroke, but they resolve completely (usually within 24 hours) without damage to brain tissue.

    Brain aneurysm: An artery in the brain develops a weak area that swells like a balloon. A brain aneurysm rupture causes a stroke, due to bleeding.

    Subdural hematoma: Bleeding on the surface of the brain; a subdural hematoma may exert pressure on the brain, causing neurological problems.

    Epidural hematoma: Bleeding between the skull and tough (dura) lining of the brain; the bleeding is typically from an artery, usually shortly after a head injury. Initial mild symptoms can progress rapidly to unconsciousness and death, if untreated. This is also referred to as an extradural hematoma.

    Intracerebral hemorrhage: Any bleeding inside the brain

    Cerebral edema: Swelling of the brain tissue which can be due to different causes, including response to injury or electrolyte imbalance

    Brain Diseases: Autoimmune Conditions

    Brain diseases linked to autoimmune conditions include:

    Vasculitis: An inflammation of the blood vessels of the brain; confusion, seizures, headaches, and unconsciousness can result.

    Multiple sclerosis (MS): The immune system mistakenly attacks and damages the body's own nerves. Muscle spasm, fatigue, and weakness are symptoms. MS may occur in periodic attacks or be steadily progressive.

    Brain Diseases: Neurodegenerative Conditions

    Brain diseases linked to neurogenerative conditions include:
