Summary

Story summary

A Swedish study finds long-term air pollution exposure raises motor neuron disease risk, including amyotrophic lateral sclerosis (ALS), by 20–30%.
The research involved 1,463 MND patients and showed that relatively low pollution levels in Sweden can accelerate progression and raise mortality.
Researchers noted that the most polluted areas show the worst outcomes, including a higher likelihood of invasive ventilation, though no causal link is established.
