Q: What is Dizziness?

      Dizziness is a feeling of imbalance or disequilibrium.  It can be marked by feeling dizzy, lightheaded, unsteady, or giddy.


Q: What is Vertigo?

     Vertigo is another sort of balance problem, marked by a sensation that you are turning or spinning.


Q: Where do I get my sense of balance?

     Your sense of balance is maintained by an interaction of several parts of the nervous system:

the inner ears monitor the directions of motion, such as turning, forward-backward, side-to-side, and up-to-down

the eyes monitor where the body is in space (i.e. upside down or rightside up) and also directions of motion

the muscle and joint sensory receptors tell what parts of the body are moving

the central nervous system (the brain and the spinal chord) processes all the bits of information from the four other systems to make sense out of everything.


Q: So, what makes me feel dizzy?

     The symptoms of dizziness appear when the central nervous system receives conflicting messages from the other four systems.   


Q: What is Motion Sickness?

     Motion sickness is a feeling of nausea or even vomiting when riding in an airplane, moving vehicle, boat (sea sickness), or amusement park ride.
