New Study Finds 2 Surprising Risk Factors for Dementia

Recent research has identified vision loss and high LDL cholesterol as new risk factors for dementia, joining a list of 12 previously recognized factors. These include hearing loss, lower education, smoking, hypertension, obesity, physical inactivity, depression, diabetes, excessive alcohol consumption, air pollution, traumatic brain injury, and social isolation. The study, which analyzed numerous recent studies, suggests that these 14 factors contribute to approximately half of global dementia cases, indicating that addressing them could significantly reduce incidence rates. Fiona Carragher, chief policy and research officer at the Alzheimer’s Society in the U.K., emphasized the importance of both lifestyle changes and societal interventions in managing dementia risk. She noted that while some factors, like alcohol consumption and physical activity, can be modified through personal choices, others require broader societal efforts. The study published in *The Lancet* highlights that elevated LDL cholesterol levels, often linked to diet and lifestyle, correlate with an increased risk of developing dementia. Dr. Murray, a practicing physician, pointed out that higher education levels are associated with a later onset of dementia. He frequently advises patients on preventive measures, reinforcing the connection between cardiovascular health and brain health. "If it’s healthy for the heart, it’s healthy for the brain," he stated, underscoring the vascular nature of the brain. To mitigate risks, individuals are encouraged to be aware of their family’s eye health history, consume a diet rich in fruits and vegetables, maintain healthy blood sugar levels, and avoid smoking.
