BACKGROUND: Clinical benefits have been reported with a specific multinutrient intervention (Souvenaid) in Alzheimer’s disease and mild cognitive impairment due to Alzheimer’s disease. The effects of Souvenaid in age-related cognitive decline are not established.
OBJECTIVE: To assess the feasibility of using virtual assessments to study the effects of a multinutrient on cognitive ageing.
DESIGN: This is a randomized, double-blind, placebo-controlled, parallel group virtual pilot trial performed over 6 months in a single-centre. Participants are randomly allocated (1:1) to receive the specific multinutrient (Souvenaid) or an isocaloric, same tasting, placebo.
SETTING: Trial visits are done virtually using secure online video communication.
PARTICIPANTS: English or Spanish speaking people aged 55−89 years from all ethnic groups and considered to have age-related cognitive decline are eligible.
MEASUREMENTS: Neuropyschological tests are done at baseline and after 6 months of intervention. Participants are contacted monthly by telephone to monitor safety, assess motivation and promote compliance. The primary outcome is feasibility determined by assessing recruitment rate, recruitment time, adherence rate and retention rate. A comprehensive set of neuropyschological measures will provide a broad assessment of cognitive function, including verbal memory, processing speed, and attention and executive function. Self-reported questionnaires are used to assess quality of life.
CONCLUSIONS: This pilot trial will provide data to guide inform selection of participants and outcome measures in future studies in age-related cognitive decline.
