Which of '.he following defines veigo: September 2011

Ans. B: Subjective sense of imbalance In veigo, patient gets a feeling of rotation of himself or of his environment. Veigo ("a whirling or spinning movement") It is a type of dizziness, where there is a feeling of motion when one is stationary. The symptoms are due to a dysfunction of the vestibular system in the inner ear. It is often associated with nausea and vomiting as well as difficulties standing or walking. The most common causes are benign paroxysmal positional veigo, concussion and vestibular migraine while less common causes include Meniere's disease and vestibular neuritis. Excessive consumption of ethanol (alcoholic beverages) can also cause notorious symptoms of veigo. A number of conditions that involve the central nervous system may lead to veigo including: migraine headaches, lateral medullary syndrome, multiple sclerosis Veigo is a sensation of spinning while stationary. Repetitive spinning, as in familiar childhood games, can induce sho-lived veigo by disrupting the ineia of the fluid in the vestibular system Veigo is classified into either peripheral or central depending on the location of the dysfunction of the vestibular pathway Peripheral: Veigo caused by problems with the inner ear or vestibular system is called "peripheral", "otologic" or "vestibular". - The most common cause is benign paroxysmal positional veigo (BPPV) but other causes include Meniere's disease, superior canal dehiscence syndrome, labyrinthitis and visual veigo. - Any cause of inflammation such as common cold, influenza, and bacterial infections may cause transient veigo if they involve the inner ear, as may chemical insults (e.g., aminoglycosides) or physical trauma (e.g., skull fractures). - Motion sickness is sometimes classified as a cause of peripheral veigo. Central: If veigo arises from the balance centers of the brain, it is usually milder, and has accompanying neurologic deficits, such as slurred speech, double vision or pathologic nystagmus. - Brain pathology can cause a sensation of disequilibrium which is an off-balance sensation.
