Chamorro language
Lytico-bodig (also Lytigo-bodig) disease, Guam disease, or amyotrophic lateral sclerosis-parkinsonism-dementia (ALS-PDC) is a neurodegenerative disease of uncertain etiology endemic to the Chamorro people of the island of Guam in Micronesia. "Lytigo" and "bodig" are Chamorro language words for two different manifestations of the same condition. "ALS-PDC", a term coined by Asao Hirano and colleagues in 1961, reflects its resemblance to amyotrophic lateral sclerosis (ALS), Parkinson's disease, and Alzheimer's disease.
