a. What is vertigo?
Vertigo is the feeling that you or your environment is moving , tilting, spinning or falling. It differs from dizziness in that vertigo describes an illusion of movement. When you feel as if you yourself are moving, it's called subjective vertigo, and the perception that your surroundings are moving is called objective vertigo. During severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall
Unlike nonspecific lightheadedness or dizziness, vertigo has relatively few causes.
b. What causes vertigo?
Vertigo occurs when there is conflict between the signals sent to the brain by various balance- and position-sensing systems of the body. Your brain uses input from four sensory systems to maintain your sense of balance and orientation to your surroundings.
d. Vertigo Medical Treatment
The choice of treatment will depend on the diagnosis.
Vertigo can be treated with medicine taken by mouth, or drugs given through an IV, to alleviate the symptoms.
In addition to the drugs used for benign paroxysmal positional vertigo, several physical maneuvers can be used to treat the condition.
Vestibular rehabilitation exercises, also referred to as Epley maneuvers, consist of having the patient sit on the edge of a table and lie down to one side until the vertigo resolves followed by sitting up and lying down on the other side, again until the vertigo ceases.
