Scientists are uncovering alarming connections between glucose spikes and neurodegenerative diseases like Alzheimer's, suggesting it may be a metabolic disorder rather than solely plaque-based. Elevated glucose levels in early adulthood are linked to a heightened risk of dementia, raising concerns about the potential for earlier onset. As metabolic health declines, the implications for future generations could be profound, echoing the troubling trend of rising diabetes diagnoses at younger ages.
