A new study has found a surprising connection between oral health and cognitive function in older adults. The research, led by a team of Japanese scientists, reveals that a specific aspect of oral health – oral diadochokinesis, or the speed of tongue movements – is closely associated with changes in cognitive function over time. This suggests that monitoring oral motor skills could help identify individuals at risk of cognitive decline, potentially leading to earlier interventions and better health outcomes for the aging population. The study also highlights the importance of maintaining good oral hygiene and physical fitness as we grow older.

Uncovering the Link Between Oral Health and Cognitive Function
As we age, maintaining both our physical and mental wellbeing becomes increasingly important. A recent longitudinal study conducted by researchers in Japan has shed new light on the relationship between oral health and cognitive function in older adults.
The study, published in the journal Scientific Reports, followed a group of 583 older adults with an average age of 72.7 years over the course of several years. The researchers assessed various aspects of the participants’ oral health, including the number of remaining teeth, chewing ability, tongue pressure, and a measure called “oral diadochokinesis” – the speed and coordination of tongue movements.
The key finding was that declines in oral diadochokinesis were closely linked to changes in cognitive function over time. Specifically, the researchers found that older adults with poorer performance on the oral diadochokinesis test were more likely to experience a decline in their Mini-Mental State Examination (MMSE) scores, a common measure of cognitive abilities.
Explaining the Link: How Oral Motor Skills Relate to Cognitive Function
The researchers propose several potential mechanisms to explain the connection between oral diadochokinesis and cognitive function. One idea is that reduced tongue mobility and coordination can impact swallowing and nutrition, potentially leading to nutritional deficiencies that may contribute to cognitive decline over time.
Another possibility is that oral diadochokinesis is closely related to physical fitness and overall mobility. Previous studies have shown that physical frailty is associated with a decline in cognitive function in older adults. By monitoring oral motor skills, clinicians may be able to detect early signs of physical and cognitive decline.
Additionally, the researchers suggest that communication impairments and social withdrawal, which can result from poor oral function, may also play a role in the cognitive changes observed in the study. Maintaining strong social connections has been linked to better cognitive health in older adults.
Implications for Early Detection and Intervention
The findings of this study have important implications for the early detection and prevention of cognitive decline in older adults. Oral diadochokinesis testing could potentially serve as a simple, non-invasive way to identify individuals at risk of cognitive decline, allowing for earlier interventions and better health outcomes.
By incorporating oral diadochokinesis assessments into regular health screenings for older adults, healthcare providers may be able to catch cognitive issues earlier and implement targeted interventions, such as physical therapy, nutritional counseling, or social support programs. This could help delay or even prevent the onset of more severe cognitive impairment, such as dementia.
The Importance of Maintaining Oral and Physical Health
The findings of this study also underscore the importance of maintaining good oral health and physical fitness as we age. By keeping our mouths healthy and our bodies active, we may be able to support cognitive function and reduce the risk of age-related cognitive decline.
Simple steps like regular dental check-ups, a balanced diet, and physical exercise can go a long way in promoting overall health and wellbeing in older adults. By taking a holistic approach to aging, we can work to preserve not only our physical capabilities but also our mental sharpness and cognitive resilience.
As the global population continues to age, research like this will become increasingly crucial in helping us understand the complex interplay between different aspects of health and developing effective strategies for supporting healthy aging. By staying informed and proactive about our oral, physical, and cognitive wellbeing, we can all work towards a future where older adults can thrive and enjoy their golden years.
