“…It was reported that cognitive function significantly decreased as the number of remaining teeth decreased [4, 13, 14, 16]. If teeth are lost, chewing efficiency and function are reduced, which decreases the ability to perform everyday activities and the quality of life and increases the risk of conditions like depression [20–22]. Also, the reduction of chewing functions might decrease learning and memory abilities [23–25].…”

Background To determine the effect of missing teeth on the risk of dementia onset among individuals who received tooth extractions and those who did not, based on the number of missing teeth. Methods We selected individuals who had not been diagnosed or treated for dementia between 2002 to 2011 from the National Health Insurance Service-Elderly Cohort Database (NHIS-ECD). We divided participants into two cohorts, a tooth extraction and non-extraction cohort, based on tooth loss from 2002 to 2011. After propensity score matching, there were 104,903 individuals in each cohort, and we included a total of 209,806 individuals in this study. Each cohort was grouped by sex, age, residential area, health insurance eligibility, income level, history of dental caries, history of periodontal treatment, and number of extracted teeth. We analyzed the relationship between dementia onset and these variables using logistic regression analysis. Results Individuals with tooth loss had a higher risk for dementia than those without tooth loss (odds ratio [OR] = 1.18; 95% confidence interval [CI]: 1.146–1.215). Regarding the incidence of dementia, the OR increased as the number of missing teeth and age increased, and the OR was higher for women (OR = 1.33; 95% CI: 1.286–1.367) than for men, and this difference was statistically significant ( P < 0.01). The incidence of dementia decreased with periodontal treatment (OR = 0.96; 95% CI: 0.932–0.992) and increased with dental caries (OR = 1.07; 95% CI: 1.035–1.101). Conclusions These results suggest that it is important to delay tooth loss and preserve the stable remaining teeth to help prevent dementia.

“…In fact, bolus size barely changes, thus bolus particles are larger in those not maintaining natural dentition [ 22 , 23 ]. Perceived inability to mash food has been associated with mild dysgeusia [ 24 ], digestive and psychological stress [ 25 ], as well as with depression [ 26 ]. Second, taste perception is also affected by taste bud receptors’ density and functionality.…”

“…In clinical practice, at least the pharmacological management of depression is problematic, because of the established risk of MCI due to anticholinergic medication [ 187 ]. Simple modifications though in daily routine may have considerable impact on neuropsychiatric symptoms independently of disease stage [ 2 ], addressing even disregarded physiological causes, such as chewing difficulties [ 26 ]. Positive reinforcement could also be advantageous, as reduced attention during meals has been shown to associate with poor appetite, and Geriatric Depression Scale ratings, in both MCI and AD, and despite concurrent psychoactive medication in AD [ 184 ].…”

Feeding and nutrition follow the growth trajectory of the course of life. The profound physiological changes that human body experiences during ageing affect separate aspects of food intake, from tastant perception to satiety. Concurrent morbidities, such as neurodegeneration, as seen in dementia, and metabolic syndrome, may further shape nutritional behaviours, status and adequacy. In an effort to fill the gap between the exhausting basic research and the actual needs of professionals caring for the exponentially expanding ageing population, the current review addresses major factors relevant to appetite and eating disturbances. Does age alter the perception of food modalities? Is food generally still perceived as alluring and delicious with age? Is there an interplay between ageing, cognitive decline, and malnutrition? What tools can we adopt for proper and timely monitoring? Finally, what anatomical and pathophysiological evidence exists to support a hypothesis of central regulation of metabolic perturbations in normal and accelerated cognitive impairment, and how can we benefit from it in health practice?

“…Chewing ability refers to individuals' masticatory performance in chewing selected common foods. 16 Previous studies suggested older adults who have poor chewing ability are more prone to experience insufficient nutrient intake, 17 impaired cognition, 18 and depression. 19 In addition, few community-based surveys reported chewing ability was associated with frailty.…”

AimTo investigate frailty trajectories in nursing home residents, and to test whether chewing difficulty was a significant factor associated with frailty trajectories.MethodsThis is a 1‐year prospective cohort study. Data were collected from 27 nursing home residents in China at baseline, 6 months, and 12 months. Latent class growth modeling was used to identify frailty trajectories. Multilevel multinomial logistic regression was used to test the relative risk ratios (RRRs) with 95% confidence intervals (CIs) of the chewing difficulty assessed at baseline on frailty trajectories.ResultsIn total, 269 nursing home residents were included in the analysis. Three frailty trajectories identified were non‐frailty trajectory (n = 181, 67.3%), stable frailty trajectory (n = 52, 19.3%), and progressive frailty trajectory (n = 36, 13.4%). Chewing difficulty was found among 138 (51.3%) nursing home residents. With the non‐frailty trajectory group as the reference, residents with chewing difficulty were more likely to demonstrate stable frailty trajectory (RRR = 2.55, 95% CI [1.28–5.11]) or progressive frailty trajectory (RRR = 3.46, 95% CI [1.47–8.15]).ConclusionsChanges in the frailty of nursing home residents are heterogeneous and chewing difficulty should be assessed and addressed on a routine basis in nursing homes to prevent the deterioration of frailty or reverse it.
