Description of Vertigo

DefinitionAccording to dictionary definition  Vertigo is dizziness characterized by a feeling of things moving or spinning around you. Attacks of vertigo may occur intermittently and may last from a few seconds to a few hours. They usually begin with the movement of the head.  Causes and Risk FactorsAccording to dictionary definition  Vertigo occurs when there is a mismatch between the signals being sent to the brain by the eyes and the vestibular system, part of the inner ear that provides information about motion and equilibrium to the brain. These contradictory signals may occur due to problems in the vestibular system or the brain.Vertigo occurs when there is a problem in the:1. Inner ear (peripheral vertigo) — symptoms are usually severe. They start suddenly and last for a short duration.2. Brain (central vertigo) — symptoms are relatively mild. They start slowly and last longer.
Causes of peripheral vertigo include:1. Benign paroxysmal positional vertigo (BPPV) — displacement of calcium carbonate crystals from utricle to semicircular canals of the inner ear.2. Vestibular neuritis or labyrinthitis — inflammation of any of the nerves connecting inner ear to the brain.3. Meniere €™s disease — excessive fluid in the inner ear. It is accompanied with hearing loss.4. Perilymphatic fistula — abnormal opening between inner and middle ear.5. Acute otitis media — infection and inflammation of the middle ear.6. Acoustic neuroma — a tumor on the nerve that connects the inner ear and brain.7. Labyrinthine concussion €“ injury to the labyrinth8. Motion sickness9. Foreign body in ear canal
Causes of central vertigo include:1. Vertebral-basilar artery insufficiency — decreased blood flow to the back of the brain2. Cerebellar hemorrhage or infarction — bleeding in the brain3. Migraine4. Tumor5. Multiple sclerosis6. Infection7. Injury to the head8. StrokeIn older people, interrupted blood supply to the brain can cause vertigo. Brain tumor and certain nerve diseases are rare causes of this condition.  Signs and SymptomsAccording to dictionary definition  Symptoms of vertigo include:1. Feeling of things moving or spinning2. Nausea3. Vomiting4. Sweating5. Headache6. Loss of control of body movements (ataxia)7. Imbalance8. Discomfort or pain in the eyes due to exposure to light9. Discomfort due to loud noise

These can help in diagnosing the cause of vertigo.Hearing tests are performed as the first step of investigations. There may be abnormal eye movements if there is a fluid imbalance in the inner ear. Symptoms will worsen with a change in position if the person has positional vertigo.Laboratory tests are not helpful for diagnosis of vertigo. An electrocardiogram may rule out heart diseases.The following tests are done to look for brain tumors and stroke:1. Magnetic resonance imaging (MRI)2. Computerized tomography (CT)3. Magnetic resonance angiography (MRA)  TreatmentAccording to dictionary definition  Treatment for vertigo includes physical therapy that moves the head in a specific way:1. Epley maneuver is a kind of exercise to treat vertigo. It involves rotating the head in a particular way and holding it in each position for 30 seconds. This is repeated until vertigo resolves.2.
