Neurologist Estol: Lifestyle Habits Can Offset Genetic Risk for Cognitive Decline

Argentine neurologist Conrado Estol argues that lifestyle habits account for half of genetic health outcomes and that early prevention is key to avoiding chronic diseases, including cognitive decline. The claim is an expert opinion piece, not a new study, so its evidentiary basis is limited. It matters as public-health messaging that could influence individual behavior and preventive-care policy.
