| Abstract: | Balance disorders in the elderly often have several contributing causes. The search for these causes focuses on vision, proprioception, coordination and medication. The peripheral vestibular system is often overlooked. This is probably due to the fact that most clinicians overlook the vestibular system, when complaints of vertigo are missing. However, dysfunction of the vestibular system may cause imbalance without vertigo. Three cases are presented. One case illustrates several contributing causes leading to imbalance. Two other cases illustrate causes of vestibular dysfunction resulting in imbalance without vertigo: a bilateral vestibulopathy and benign paroxysmal positional vertigo. Symptoms, examination and treatment are discussed. All patients with imbalance should undergo a Head Impulse Test and Dix-Hallpike maneuver. |
