Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness, or vertigo. It causes the sensation that your body is moving even when it’s not, or that your head is spinning. BPPV results in short but sometimes very intense episodes of vertigo. Usually, these episodes of dizziness are triggered by certain changes in head positioning, such as moving the head vigorously from side to side, leaning down for extended periods, or other sudden movement. The movement is said to cause calcium deposits in the inner ear to dislodge, which move across internal structures of the ear. This causes the ear to send signals to the brain that the body is in motion. Usually, benign paroxysmal positional vertigo (BPPV) is very bothersome for the patient but of little cause for concern other than protecting patients from falls due to loss of balance. One cause of BPPV is TMJ/TMD, or temporomandibular joint dysfunction.
