Dementia, a debilitating condition that affects many individuals, is often misunderstood as an unavoidable part of aging. While the risk of developing dementia increases with age, it is not a guaranteed outcome.
Dementia is primarily caused by a range of diseases, with Alzheimer’s disease being the most common.
As researchers seek out prevention strategies, recent developments offer promising new avenues for reducing the risks.
A recent study published in Nature Medicine reveals intriguing findings about the shingles vaccine. Researchers found that individuals who received the latest shingles vaccine lived, on average, 164 days longer without a dementia diagnosis compared to those who received the previous version of the vaccine.
While the exact reasoning by which the vaccine influences dementia risk is still unclear, Dr. Sheona Scales, Director of Research at Alzheimer’s Research UK, emphasizes the need for continued research to fully understand their findings.
The Centers for Disease Control and Prevention (CDC) currently recommends that individuals begin the two-dose shingles vaccination series at age 50.
There is growing interest in exploring whether earlier vaccination, potentially starting in the 20s or 30s, could offer additional benefits in preventing dementia.
On a recent edition of “CBS Mornings,” Dr. Céline Gounder, an editor-at-large for KFF Health News, highlighted this development as a significant advancement in preventive health.
“The fact that we have a vaccine that's already approved, already out there, covered by insurance, super easy to get. The fact that that is showing this kind of level of protection is really promising for a lot,” Gounder noted.
While the shingles vaccine is an advancement, other preventive measures are equally important.
Researchers suggest air pollution may be to blame for thousands of dementia cases each year. Examples include exposure to wildfire smoke and 911 first responders, highlighting the potential link between air pollutants and an increase risk of developing dementia.
Dr. Gounder emphasizes that dementia prevention extends beyond vaccination. “You want to control your blood pressure, avoid developing diabetes through good diet and exercise, but if you have diabetes, be sure to manage it well, quit smoking,” she advises.
Maintaining a healthy lifestyle through diet and regular physical activity, controlling blood pressure, and managing chronic conditions such as diabetes are crucial steps in reducing the risk of dementia.
Although the shingles vaccine is promising, experts urge people to recognize the importance of other methods' role in prevention
Health guidelines to follow include undergoing regular medical screenings throughout each decade of life, from your 20s to your 60s, and taking specific preventive actions in your 50s to address other health concerns.
As research progresses and guidelines evolve, individuals are encouraged to stay informed and proactive about their health to mitigate the risks associated with dementia.
