Vertigo, which on a broader scale is considered to be dizziness, is actually a form of perception of motion disorder. There are various causes of vertigo but the most common cause is a dysfunctional vestibular system (sensory system responsible for maintaining balance). Slight change in the head position can trigger dizziness which can last from a few seconds to a couple of minutes.
What is BPPV?
Benign Paroxysmal Positional Vertigo or BPPV is the most commonly occurring types of vertigo. As the name suggests it is harmless or it isn’t life threatening (benign), it occurs suddenly and for short periods (paroxysmal positional). Our body’s vestibular system malfunctions to cause a perception of motion or false motion even through slightest movement of the head.
The octoconia sometimes get dislodged from their original location which is the utricle and get deposited in the semicircular canals. After this dislocation when our head moves these calcium carbonate crystals stimulate the sensory receptors and send out false signals creating a perception of motion.
If constant dizziness after head movements is something you suffer with all the time then it is better to get yourself diagnosed.
