Identified New Potential Factors for Minimizing Dementia Risk: Insight into 3 Modifiable Elements
In the ongoing battle against dementia, new research has identified three modifiable risk factors that, if addressed, could potentially prevent or delay up to 20 million cases of the disease worldwide. The Lancet Commission has highlighted excessive alcohol consumption, head injuries or traumatic brain injuries (TBIs), and air pollution as key areas of focus.
Excessive alcohol consumption, defined as regularly drinking more than 21 units per week, has been linked to an increased risk of dementia. Research suggests that even moderate consumption may accelerate brain atrophy and the buildup of harmful proteins associated with Alzheimer's disease. Strategies to reduce this risk include moderating alcohol intake or abstaining, increasing awareness of alcohol’s cognitive effects, and promoting access to interventions for alcohol misuse.
Head injuries, a known risk factor for dementia, can be prevented through a variety of means. Wearing protective gear, taking precautions to avoid falls, and implementing prevention and early intervention efforts can help prevent brain injuries. This is particularly important in high-risk groups, such as older adults and those involved in contact sports.
Air pollution, specifically exposure to PM2.5, nitrogen dioxide, and soot, has also been linked to an increased risk of dementia. These pollutants contribute to chronic inflammation and oxidative stress linked to cognitive decline. Policies to reduce pollution include stricter vehicle emission standards, promoting clean energy sources, enhancing air quality monitoring, planning urban green spaces, and encouraging public transport or low-emission vehicles.
Governments play a crucial role in improving air quality, particularly in areas with high air pollution. This is a significant step towards lowering the risk of dementia due to air pollution.
Public health initiatives, such as ad campaigns, could help lower harmful alcohol drinking and reduce dementia cases. Furthermore, programs that teach healthy relationship skills can prevent violence, which can lead to brain injuries.
It's important to note that more than one TBI increases the risk of dementia further, and evidence suggests that heavy drinking is linked to changes in the brain, learning and memory performance, and dementia. However, the relationship between alcohol and dementia is complex due to cultural patterns and other sociocultural and health-related factors.
A study of older adults with concussion found their risk of dementia doubled, but those taking statins had a 13% reduced risk of dementia compared to those who were statin-free. Statin use might mitigate injury-related brain edema, oxidative stress, amyloid protein aggregation, and neuroinflammation, all factors contributing to the development of dementia.
In conclusion, addressing these modifiable risk factors can significantly contribute to lowering dementia risk by addressing environmental and lifestyle factors associated with brain health decline. By taking action on excessive alcohol consumption, head injuries, and air pollution, we can make a meaningful impact on the global dementia crisis.
