Dizziness

Dizziness can be defined as the experience of the perception of motion (usually a spinning motion). It is often associated with nausea and vomiting as well as a loss of motor control, causing difficulties standing or walking.

The medical literature lists three types of dizziness:

1. Objective - The first is known as objective and describes when the patient has the sensation that objects in the environment are moving
2. Subjective - the second is known as subjective and refers to when the patient feels as if he or she is moving
3. Psuedovertigo - the third is known as pseudovertigo, an intensive sensation of rotation inside the patient's head.
