Gum Disease Linked to Brain Vessel Damage, New Study Suggests
New research indicates a potential connection between gum disease and damage to small blood vessels in the brain, potentially increasing risk factors for cognitive decline. A study published in Neurology Open Access reveals individuals wiht gum disease exhibited a higher prevalence of white matter hyperintensities (WMHs) – areas of damage in the brain often associated with age-related cognitive issues like problems with balance, memory, and reasoning.
Researchers analyzed data from over 500 participants, finding a statistically significant association between gum disease and increased WMHs, even after accounting for other vascular risk factors. While the study doesn’t prove causation, it adds to a growing body of evidence suggesting oral health plays a crucial role in overall brain health.
“Gum disease is preventable and treatable,” says researcher Dr. Sengupta (Sen), highlighting the potential for preventative measures. “If future studies confirm this link, it could offer a new avenue for reducing cerebral small vessel disease by targeting oral inflammation.”
WMHs are thought to represent underlying brain injuries and frequently increase with age. The study suggests chronic inflammation, known to spread throughout the body, may be a key factor linking gum disease to brain vessel damage. This builds on previous research from the same team, which found an association between gum disease, tooth cavities, and a higher risk of stroke.
Considering almost half of adults in the US have some form of gum disease, addressing oral health could have widespread benefits. Though, researchers acknowledge the possibility of shared risk factors impacting both gum and brain health.
“While more research is needed to understand this relationship, these findings add to growing evidence that keeping your mouth healthy may support a healthier brain,” Sen stated.
