In the know.

There is a paradigm-shifting in the way experts are viewing dementia. For years dementia has been perceived as an inevitable part of the aging process, especially if genetics are not in your favor. However, a new study by the Lancet Commission on Dementia reports dementia could be prevented, with an estimated 50% of cases worldwide that could be either fully prevented or delayed.

How? Researchers point to fourteen modifications, mostly behavioral, one can make to address the key risk factors of the disease. The best news for some is that these modifications can be benefitable, despite the perceived genetic risk.

The 14 risk factors for Dementia:

• lack of physical activity
• cigarette smoking
• excessive alcohol consumption
• obesity
• hypertension
• high cholesterol
• diabetes
• social isolation
• depression
• untreated hearing
• untreated vision loss
• low educational attainment (associated with low cognitive engagement)
• traumatic brain injury
• air pollution or poor air quality

While many of the items on this list have been reported in the Lancet Commission on Dementia's previous 2020 report, two items have only been added to the list this year; high cholesterol and vision loss.

While items on the list like air pollution may rely on public policy and are largely out of an individual's control, the bulk of the risk factors can be improved. Experts suggest that those who wish to take action on dementia prevention should work closely with healthcare providers as they are modifying their behavior while also seeking treatment for existing conditions. Of course, regular health screenings are a key component to reducing the risk of dementia.
