On an island where a debilitating and incurable disease has long moved largely unseen, Puerto Rico has built its first systematic record of amyotrophic lateral sclerosis — and the map it reveals is uneven in ways that demand explanation. Between one and two residents per 100,000 develop ALS each year, a rate familiar to epidemiologists worldwide, yet two regions, Arecibo and Caguas, carry a disproportionate burden that points toward something local and still unnamed. Researchers are now tracing the threads of environment, genetics, and social circumstance, understanding that for a disease with

Long-term Care and Hospice Services
ALS patients and families face significant out-of-pocket costs for specialized care, assistive devices, and long-term care services. The registry may improve early diagnosis access but could increase healthcare demand in affected regions, potentially straining local medical resources and insurance coverage.
Puerto Rico's government may need to increase funding for neurology services, establish specialized ALS treatment centers, and investigate environmental hazards in Arecibo and Caguas. The registry could inform public health policy on disease surveillance, healthcare infrastructure investment, and environmental health regulations.
