ALS May Start in Cerebellum, Study Finds

Scientists in Quebec may have uncovered a major breakthrough in ALS research, pinpointing a key enzyme in the cerebellum—long before motor symptoms appear—that’s crucial for DNA repair. When this enzyme fails, DNA damage accumulates, triggering neuron death. Using zebrafish models, researchers found early-stage damage and, crucially, that boosting the enzyme’s activity reversed damage and saved neurons. This could lead to earlier diagnosis and new therapies for the 3,000+ Canadians living with ALS, offering hope for halting progression before it starts.
