Question

How are vertigo and motion sickness related?

Answer 1

Vertigo, motion sickness and dizziness are related to the sense of balance and equilibrium.

Explanation:

They occur when the Central Nervous System receives conflicting messages from the balance organs, eyes, muscles and joint sensory receptors.

VERTIGO
There are a number of different causes of vertigo. Central causes of vertigo arise in the brain or spinal cord while peripheral vertigo is due to a problem within the inner ear. The inner ear may become inflamed, or displaced crystals may irritate the small hair cells within the semicircular canals, leading to Benign Paroxymal Positional Vertigo. Fluid built up within the inner ear may also cause vertigo. Head injuries causing damage to inner ear, strokes, multiple sclerosis or tumor, and basilar artery migraine may also develop symptoms of vertigo.

MOTION SICKNESS
This is a feeling one gets when the motion sensed by the inner ear is different from the motion visualised. It is a common condition that occurs in some people who travel by car, train, airplane or boat. It is caused by the mixed signals send to the brain and inner ear. If one cannot see the motion the body is feeling or conversely if one does not feel the motion the eyes see, then the brain gets mixed signals and the person develops some aspect or symptoms of motion sickness.
