Meniere's syndrome. Meniereâs syndrome is also a significant cause of dizziness in the older population and has its highest incidence above fifty years of age. Meniereâs syndrome usually presents as spells of rapid decline in hearing, a roaring tinnitus, vertigo, and monaural fullness.
Common causes of dizziness include a migraine, medications, and alcohol. It can also be caused by a problem in the inner ear, where balance is regulated. Dizziness is often a result of vertigo as well. The most common cause of vertigo and vertigo-related dizziness is benign positional vertigo (BPV). This causes short-term dizziness when someone changes positions quickly, such as sitting up in bed after lying down. Dizziness and vertigo can also be triggered by Meniereâs disease. This causes fluid to build up in the ear with associated ear fullness, hearing loss, and tinnitus. Another possible cause for dizziness and vertigo is an acoustic neuroma.
