In a Scandinavian autopsy series, dementia was reported in 2-6% of patients with MND. The relative frequency of FTD/MND in all patients with dementia appears similar in the United States and Japan. Certain populations (eg, Chamorro Indians of Guam, indigenous residents of the Kii Peninsula) have a disproportionately higher incidence and prevalence of overlap degenerative syndromes (MND, dementia, parkinsonism).
