Treating Central Vertigo After Lateral Medullary Stroke With Low-Dose Olanzapine in Acute Inpatient Rehabilitation.

Vertigo is a common neurological symptom and can be a distressing and disabling condition. Vertigo has peripheral and central etiologies. Although there are useful treatments for many peripheral cases, there is a notable absence of effective treatments for central vertigo. We describe the case of a 74-year-old male presenting with severe vertigo after a lateral medullary stroke persisting through 8 days of acute inpatient rehabilitation. Low-dose olanzapine (2.5 mg nightly) was then initiated with complete resolution of his debilitating dizziness 2 days later, followed by a successful rehabilitation course and eventual return home.
