Background: Dementia prevention is a global public health priority. The FINGER multimodal lifestyle intervention is the only intervention model so far that has demonstrated significant cognitive and other health benefits in at‐risk older adults. LETHE proposes a new multimodal precision prevention approach where FINGER intervention is complemented with digital tools to optimize intervention delivery, personalize recommendations based on individual risk profile, and support risk factor self‐management. The multinational 2‐year randomized controlled LETHE pilot trial aims to test the feasibility of a digitally supported, adapted FINGER intervention among older adults at risk of cognitive decline and dementia. Method: A total of 160 individuals aged 60‐77 years and with risk factors for dementia but no substantial cognitive impairment are recruited at four sites (Austria, Finland, Italy, Sweden; N = 40 per country). Digital readiness and experience with smart devices are required. Participants are randomized 1:1 to 1) structured multimodal lifestyle intervention (dietary guidance, exercise, cognitive training, vascular/metabolic risk management, social stimulation, sleep/stress management) where in‐person individual and group‐based activities are supported with the LETHE smartphone app developed in the project; or 2) self‐guided lifestyle intervention (regular health advice and access to a simplified app with no personalized/interactive content). Both groups wear a smartwatch to gather passive data (e.g., activity, sleep). Primary outcomes are retention rate, adherence to intervention and engagement with the app, and change in dementia risk based on validated risk scores (CAIDE, LIBRA). Secondary outcomes are lifestyle changes and changes in cognition, stress‐related symptoms, sleep, health‐related quality of life, and health literacy. Participant experiences will also be explored. The LETHE Advisory Board (members of the public) provided feedback on the trial protocol. Result: Trial is registered at ClinicalTrials.gov (NCT05565170), and ethical approval has been obtained in each country. Recruitment started in September 2022 and will be completed in Spring 2023. Updates and results on study progress will be presented. Conclusion: LETHE pilot trial will inform about the feasibility of technological solutions and a digitally assisted lifestyle program to support brain health among older adults. If proved to induce sustained behavioural changes, digital tools could offer potential for large‐scale, cost‐effective dementia prevention programs. [ABSTRACT FROM AUTHOR] |
