If you're in the San Francisco Bay Area, you may want to check out a movie documenting the illness known as Lytico-Bodig and the way it specifically affected our island, and perhaps a focus on Umatac, pictured above in the 1950s.
From the San Francisco Film Society website :
Local filmmaker Berry Minott takes us on an epic journey to find the cause—and perhaps the cure—of Alzheimer’s, Parkinson’s, ALS and other neurological disorders. Her investigation begins on the Pacific island of Guam, where following the end of WWII, the indigenous Chamorro people were afflicted with Alzheimer’s-like symptoms from a disease called Lytico-Bodig. For years renowned scientists descended on this small village to detect the source of this mysterious illness—was it hereditary, environmental or dietary? This engaging and edifying documentary features rare archival footage and candid interviews with author/neurologist Oliver Sacks, New Yorker columnist Jonathan Weiner and many other noted scientists.
