What is the medical term meaning lightheaded?

Answer 1

When you turn, fluid inside of your inner ear moves and stimulates nerve cells. This is how you know when your head is changing direction. Usually, feeling dizzy means that the fluid in your semicircular canals is still spinning after you have stopped, signaling the brain that you are still spinning. This makes you feel like you are spinning, even though you are not.

Answer 2

Vertigo Vertigo, or dizziness, is a symptom, not a disease. The term vertigo refers to the sensation of spinning or whirling that occurs as a result of a disturbance in balance (equilibrium). It also may be used to describe feelings of dizziness, lightheadedness, faintness, and unsteadiness. The sensation of movement is called subjective vertigo and the perception of movement in surrounding objects is called objective vertigo. Vertigo usually occurs as a result of a disorder in the vestibular system (i.e., structures of the inner ear, the vestibular nerve, brainstem, and cerebellum). The vestibular system is responsible for integrating sensory stimuli and movement and for keeping objects in visual focus as the body moves. Benign paroxysmal position vertigo (BPPV) is a common cause for dizziness. When the head moves, signals are transmitted to the labyrinth, which is an apparatus in the inner ear that is made up of three semicircular canals surrounded by fluid. The labyrinth then transmits movement information to the vestibular nerve and the vestibular nerve carries the information to the brainstem and cerebellum (areas of the brain that control balance, posture, and motor coordination). There are a number of different causes for dizzy spells. Incidence and Prevalence

Vertigo is one of the most common health problems in adults. According to the National Institutes of Health (NIH), about 40% of people in the United States experience feeling dizzy at least once during their lifetime. Prevalence is slightly higher in women and increases with age. http://www.neurologychannel.com/vertigo/index.shtml
