Three ways to help prevent dementia and Alzheimer’s disease

June is here—and in addition to officially kicking off summer, it’s also Alzheimer’s and Brain Awareness Month. While June is used to recognize and support those experiencing cognitive decline, it can also be a month for both young and old to take proactive steps to achieve and maintain optimal brain health.

Among older adults, Alzheimer’s disease is the most common cause of dementia, and the seventh leading cause of death in the U.S. This brain disorder starts slowly—possibly decades before symptoms appear—making identifying protective factors early in life critical. 

Though typically categorized as a disease for older adults, anyone can take steps now to potentially reduce their risk of developing Alzheimer’s and dementia.

Three ways to help prevent Alzheimer’s disease and dementia

Making certain lifestyle adjustments may favorably influence cognitive status. Collectively, combining the three approaches below has the potential to delay the onset of dementia based on promising research, though further studies are needed to make specific recommendations. 

1. Eating a nutritious heart-healthy, mindful diet 

Several different eating styles may offer benefits for brain health, including the Mediterranean diet and Dietary Approaches to Stop Hypertension (DASH). Part of their protective benefit may be due to the inclusion of anti-inflammatory and antioxidant rich foods. The Institute of Medicine, Alzheimer’s Association and American Heart Association recommend a heart-healthy diet for brain health. 

Vitamin D deficiency is a risk factor for Alzheimer’s disease. If you’re vitamin D deficient (detectable through a blood test), talk to your doctor about supplementation.

2. Engaging the brain 

Engaging the brain through cognitive stimulation is all about using and challenging the mind. This includes solitary and group activities that involve thinking, reasoning skills and activating memory. One study showed that engaging in cognitive activities during midlife was associated with a significantly reduced risk of dementia (from all causes), after adjusting for factors such as prior disease state, age, and BMI. Leisure activities, that engage the brain, may improve processing speed and benefit memory.

3. Exercising

Regular exercise protects brain health in several ways, including reducing stress. This is vital, as chronic work-related stress has become an emerging risk factor for Alzheimer’s disease

Staying active promotes mind-body health and benefits your microbiome, or gut bacteria. This influences brain health through the gut-brain axis. 

The impact of preexisting health conditions

Having preexisting conditions such as diabetes, hyperlipidemia and hypertension can increase the risk of developing dementia. Make sure your employees don’t ignore these additional warning signs and are actively working to manage them. 

Many people are unsure whether they have or might be at risk for having these conditions. Encourage them to participate in your company’s health screening event and make an appointment with their primary care physician for an annual physical.
