Multiple sclerosis is an autoimmune disease that affects the brain and spinal cord (central nervous system.
|
 |
Multiple sclerosis (MS) is a chronic autoimmune disorder affecting movement, sensation, and bodily functions. It is caused by destruction of the myelin insulation covering nerve fibers (neurons) in the central nervous system (brain and spinal cord).

Labyrinthitis is an ear disorder that involves irritation and swelling of the inner ear. See also: Meniere's disease
|
 |
Labyrinthitis is an inflammation of the inner ear that is often a complication of infection of the middle ear ( otitis media ). It is usually caused by the spread of bacterial or viral infections from the head or respiratory tract into the inner ear.

Benign positional vertigo is condition in which a person develops a sudden sensation of spinning, usually when moving the head. It is the most common cause of vertigo.

A migraine is a common type of headache that may occur with symptoms such as nausea, vomiting, or sensitivity to light. In many people, a throbbing pain is felt only on one side of the head. Some people who get migraines have warning symptoms, cal...

The following Clinical Topic Tour provides an overview of migraine headache and has been adapted from materials published by the National Institute of Neurological Disorders and Stroke.

|
A headache signifies activation of the primary afferent fibers that innervate cephalic blood vessels, chiefly meningeal or cerebral blood vessels. Most nociceptive fibers innervating these structures arise from pseudounipolar neurons located within the trigeminal ganglia (first division), although some may be located within the upper cervical ganglia.

Vertebrobasilar circulatory disorders are conditions in which blood supply to the back of the brain is disrupted. See also: Transient ischemic attack; Stroke.
|
|
Cerebral vascular insufficiency is defined as insufficient blood flow to the brain. The most common cause of decreased blood flow is atherosclerosis of the arteries that supply blood to the brain.

An acoustic neuroma is a noncancerous (benign), often slow-growing tumor of the nerve that connects the ear to the brain. It is located behind the ear right under the brain.

An acoustic neuroma is a benign tumor involving cells of the myelin sheath that surrounds the vestibulocochlear nerve (eighth cranial nerve).
