Investigators have identified a genetic variation associated with an earlier age of onset in Alzheimer's disease. Unlike genetic mutations previously linked to rare, inherited forms of early-onset Alzheimer's disease -- which can strike people as young as their 30s or 40s -- these variants influence an earlier presentation of symptoms in people affected by the more common, late-onset form of the disease.
