A chance to prevent Alzheimer's disease sooner than you think

Alzheimer's disease is the most common form of cognitive impairment. With increasing longevity, its prevalence continues to grow, and treatments that prevent its clinical onset would have a profound effect. Characterised by amyloid plaques, tau tangles, and neuronal loss, Alzheimer's pathology is already extensive and hard to stop by the time cognitive impairment is detected. Secondary prevention therapies have the potential to avert further disease progression and to stop or delay cognitive impairment in people with biomarker evidence of the disease.
