Will an infection today lead to dementia tomorrow?
If you are looking for ways to steer clear of memory issues later in life, try to avoid common infections.
A recent study found a link between severe infections and neurological conditions. Participants who experienced severe respiratory tract infections, herpes and even skin infections had an increased risk of developing Alzheimer’s disease.
The more severe the infection, the greater the chances for long-term consequences. For example, infections that required hospitalization doubled the risk of dementia. In comparison, minor infections had only a 2% chance of leading to dementia.
“Bacterial or viral infections can result in a loss of brain mass, which can make it harder for the brain to function properly,” explains Dr. Rebecca Stormont, an internal medicine physician at Aurora Health Care. “This may lead to lower cognitive performance, making it more difficult to recall memories, hold thoughts or even express yourself.”
Infections may also make it more difficult for blood to flow properly to the brain. This can cause vascular dementia, the second most common dementia diagnosis after Alzheimer’s.
Fortunately, Dr. Stormont says making certain lifestyle changes can support a healthy immune system, which allows you to fight off infections and reduce your risk of dementia.
4 lifestyle changes to support a healthy immune system:
1. Exercise
One surefire way to improve your immunity is with routine exercise. Exercise boosts antibodies and white blood cells that can detect illness and infection sooner. Adults can help their body repel infectious diseases by getting 150 minutes of moderate aerobic exercise each week and muscle training at least two days a week.
2. Get quality sleep
Your body creates proteins called cytokines while you sleep. The release of cytokines into your bloodstream stimulates your immune system and produces healthy blood cells. The more sleep you get, the more optimized your body is to fight off infections.
3. Be mindful of alcohol consumption
Drinking can weaken your immune system and harm beneficial bacteria in your body. Heavy drinking also reduces the number of antibodies available to recover from illness and fight off infection.
4. Improve your dietary habits
Fueling your body properly is essential to prevent infections and combat them once they occur. The micronutrient vitamin C is essential for fighting off infections, reducing inflammation and meeting your metabolism’s energy needs. Additionally, healthy levels of vitamin A can support your body’s energy levels, allowing you to stave off infections and boost your immune response. Antioxidants have a similar effect.
