The relationship that exists between the ear crystals and dizziness is that crystals that form in the inner ear can cause dizziness. The condition is called benign paroxysmal positional vertigo (BPPV). This symptom of vertigo or dizziness occurs when a person moves or changes the position of his head; this causes calcium crystals to move about in the semicircular canal of the inner ear, states Johns Hopkins Medicine.
These crystals, which are found in the utricle, are called otoconia. Crystal particles tend to shift from the utricle, which is in the inner ear, to another area of the inner ear called the semicircular canal. Some other symptoms associated with BPPV are nausea and vomiting. Although there is no one specific cause for this condition, it is more common in people over the age of 60. Similarly, a head trauma or vestibular disorder can be risk factors, states Mayo Clinic.
In some cases, benign paroxysmal positional vertigo can resolve on its own in a couple of weeks. However, if it does not and symptoms are very troubling, then a common treatment for BPPV is physical therapy in which head exercises are used to shift the crystals out of the semicircular canal to an area where they will not cause trouble, explains WebMD. Some names for these exercises are the Epley and Semont maneuvers and Brandt-Daroff exercises.
