Have you ever felt like you or the world around you is spinning? You are not alone. Vertigo could be causing it.
DECIPHERING MEDICAL JARGON Vertigo: A sensation of spinning or unsteadiness accompanied by feeling of movement within the head.
Vertigo is a symptom of several conditions. The causes of vertigo include benign paroxysmal positional vertigo (BPPV), head trauma, labyrinthitis, vestibular neuritis and Meniere’s disease. We’ll be focusing on BPPV in this post.
In the inner ear, there is a three loop-shaped structure (semicircular canals), containing fluid and fine, hair-like sensors that monitor the head rotation (up and down, right and left, back and forth). Other inner ear structures (otolith organs) containing calcium crystals, stimulate the vestibular nerve to send signals to the brain about head and body movements in relation to gravity.
Normally, these calcium crystals are static and adherent to the otolith organs. However, when they become dislodged, and move into one of the semicircular canals, it causes the canal to become sensitive to head position changes that it’s not used to. As a result, one will feel dizzy.
These symptoms are usually provoked by head motion, looking up or down. The spinning sensation is usually violent but brief, lasting less than one minute.
Treatment for vertigo depends on the underlying cause. Usually it resolves on its own within a few weeks or months. For some, treatment may be needed, such as:
