High prevalence of Kennedy's disease in Western Finland - is the syndrome underdiagnosed?

Abstract

Kennedy's disease is the most common motor neuron disorder in the Vasa region, exceeding the prevalence of ALS by a factor of two, and far more common than any of the other motor neuron disorders. The fact that none of our patients, despite previous examinations, had correct diagnoses before 1995, indicates that Kennedy's disease still might be relatively underdiagnosed.
