Study Examines ALS Incidence Among American Indians, Alaska Natives
JAMA Neurology Study Highlights
A study by Paul H. Gordon, M.D., Ph.D., of the Indian Health Service, and colleagues analyzed electronic records for American Indians and Alaska natives (AI/ANs) with amyotrophic lateral sclerosis (ALS) and motor neuron disease separately from 2002-2009 to estimate the incidence and prevalence of the diseases. (Online First)
A total of 71 AI/ANs were diagnosed with ALS, yielding an average annual crude incidence rate of 0.63 cases per 100,000 and age-adjusted incidence of 0.92 per 100,000. The crude and age-adjusted incidence rates for motor neuron disease were 1.08 and 1.50 per 100,000, respectively, according to the results.
"The incidence of ALS among AI/ANs appears to be lower than that reported for white populations, a finding congruent with reports of other minority populations. Community-based studies are important to confirm these findings and to examine reasons for the low rate of ALS among AI/ANs," the study concludes.
