BPPV (benign paroxysmal positional vertigo) is the most common cause of dizziness — it produces brief spinning sensations when moving the head in specific directions and is easily treated. If tinnitus and hearing loss accompany the dizziness, Meniere's disease should be evaluated. Standing-only dizziness often points to orthostatic hypotension.
