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.
