New Dementia Risk Factors Discovered: Beyond Memory Loss

New research highlights two crucial, preventable dementia risk factors beyond memory loss: high ‘bad’ cholesterol in mid-life and untreated vision loss in later years. These factors, now recognized by the Lancet Commission, contribute significantly to dementia cases. Early detection and management of these conditions offer a hopeful path to protecting brain health. When we hear the word ‘dementia,’ most of us think of elderly people having memory problems — they don’t remember the names of their dear ones, where they put the house keys, or whether they paid the bills or not. In short, dementia generally reminds us of how a progressive brain disorder can affect the cognitive abilities of people. And often we take signs of memory loss as the symptoms of the same disorder. However, new research is shedding light on two important — and preventable — risk factors we didn’t pay attention to until recently. While memory loss and age remain the most familiar warning signs of dementia, scientists now say that high ‘bad’ cholesterol (LDL) in mid-life and untreated vision loss in later years also significantly raise the risk.
