Purpose Dysphagia in persons living with dementia (PLWD) is raising concern due to the absence of swallowing treatments specific to this population. Dysphagia can result in detrimental effects, such as malnutrition, dehydration, and aspiration pneumonia. This systematic review aimed to evaluate the existing literature on dysphagia management of PLWD and reveal their limitations to facilitate clinical practitioners in decision-making. Methods Five electronic databases were searched systematically from the date of inception to January 2024 by two independent reviewers. Eligible studies investigated any treatments with outcome measurements evaluating swallowing function. Qualitative analyses were performed. Results A total of 10 studies, involving 1360 participants, were included in the systematic review. They were analyzed qualitatively and evaluated for quality. Studies included were observational (n = 5) with prospective or retrospective designs, and randomized controlled trials (n = 5). Compensatory, rehabilitative, stimulation, and pharmacological treatments were addressed. Conclusion There is currently limited evidence available revealing the efficacy of dysphagia treatments for PLWD. Based on the current evidence, no definitive conclusions can be drawn on which treatments are more effective for this population. In the future, more randomized controlled trials with large sample sizes investigating the long-term effects of treatments are warranted.

Purpose of review The aim of this study was to conduct a review of the literature published over the past 18 months and present the latest findings on hydration in individuals with dementia. Recent findings A systematic review identified sarcopenia, polypharmacy, delayed oral transit, and poor rinsing ability as markers of eating-drinking-swallowing difficulties in early-stage dementia. A cross-sectional study found a high prevalence of dehydration (57–68%) among dementia patients, associated with hypertension, diabetes, chronic kidney disease, dysphagia, and cognitive decline. An analysis of national dementia care guidelines showed that only the UK and Switzerland addressed assisted nutrition and hydration. “Jelly Drops,” a hydrating product for dementia patients, received innovation awards. A study on US Physician Orders for Life Sustaining Treatment forms highlighted inconsistent terminology for end-of-life nutrition and hydration, calling for clearer language to aid decision-making. Summary The new hydration-related recommendations in the ESPEN 2024 guidelines for dementia reflect a more individualized, proactive, and comprehensive approach to managing hydration. These guidelines emphasize the importance of early detection, personalized interventions, and consistent monitoring to ensure that dehydration is identified and treated promptly. Furthermore, the current literature supports the need for a specific terminology for dementia management using nutrition and hydration to improve patients’ health outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
