title: Treatment of acquired periodic alternating nystagmus with memantine: a case report.
abstract: We report a case of acquired periodic alternating nystagmus associated with common variable immunodeficiency and cutaneous sarcoid. The patient was initially treated with baclofen with minimal subjective improvement. We found a significant improvement in the patient's symptoms and nystagmus intensity after treatment with memantine.
