Motor neuron disease disability rates increased in the Americas from 1990 to 2023
Original source
The burden of noncommunicable and injury-related nervous system disorders in the Americas, 1990-2023: an analysis of the Global Burden of Disease Study 2023. (opens in a new tab)Compass summarised this from the study's abstract.
A Global Burden of Disease Study 2023 analysis found that age-standardised disability-adjusted life-year rates for motor neuron diseases increased in the Americas between 1990 and 2023. The analysis covered 38 countries and territories and estimated the burden of 19 nervous system disorders.
Why this matters
This indicates a worsening population-level disability burden from motor neuron diseases in the region. It is an epidemiological finding and does not show that any treatment improves outcomes or change clinical care for an individual.
Limitations and context
The results are estimates from the Global Burden of Disease Study 2023, not direct counts of every case. The source reports motor neuron diseases as a group and does not provide disease-specific figures in the supplied abstract. The analysis describes population trends and does not test treatments or explain why rates increased.
