Many people have experienced the spinning sensation after an amusement park ride or after spinning around for a period of time and then stopping quickly.  Vertigo is a specific type of dizziness where the person feel as if the room were spinning, which gets worse with head movement.  The person might have visual disturbances, weakness, difficulty speaking, a decreased level of consciousness, and difficulty walking.  Dizziness and vertigo are not diseases in themselves. They are symptoms which indicate that something is wrong and can have different causes. 


Four ‘Vestibular Nuclei’ (superior, lateral, medial, and inferior) provide us with the ability to maintain balance while standing or walking.  They are located in the brainstem, within an area in the lower rear part of the brain connected to the spinal cord.  During ‘Vestibular Neuronitis’ there is an inflammation of the vestibular nerve which carries sensory data from the inner ear about head movement.
