Study Overview
Brief Summary
Lifestyle Intervention in the memory clinics of General and academic Hospitals Trial (LIGHT) is a multi-center, randomized, controlled, lifestyle intervention trial among 300 older adults (≥50 years) with subjective cognitive decline (SCD) and mild cognitive impairment (MCI) at risk of dementia. Participants are randomized in a 1:1 ratio to Group A (tailored lifestyle intervention) or Group B (general health advice) for a duration of 12 months. The lifestyle intervention comprises three parts 1) Lifestyle coaching, 2) a voucher program, and 3) online self-management. Group B will receive general health advice.
Detailed Description
Rationale: Dementia prevention through lifestyle has much potential but is not implemented in routine care. Patients referred to memory clinics, such as people with mild cognitive impairment (MCI) and subjective cognitive disorder (SCD), are at high risk for dementia and tend to have a worse health and lifestyle profile. While they might greatly benefit from lifestyle changes, there is no offer to help them make those changes.
Objective: The primary objectives are to examine both the (cost-)effectiveness of an innovative 1-year lifestyle intervention on lifestyle change measured by the validated Lifestyle for Brain Health Score (LIBRA) in older adults with SCD or MCI; and to identify possibilities, barriers, and facilitators for sustainable implementation of the lifestyle intervention.
Study design: Multicenter, randomized controlled trial comparing a lifestyle intervention with care as usual and general health advice.
Study population: 300 older adults (≥50 years) with SCD and MCI at risk of dementia.
Intervention: Participants are randomly allocated on a 1:1 ratio to participate either in Group A (tailored lifestyle intervention) or Group B (general health advice) for a duration of 12 months. The lifestyle intervention comprises three parts 1) Lifestyle coaching, 2) a voucher program, and 3) online self-management. Group B will receive general health advice.

Outcomes
Primary Outcomes
Lifestyle for BRAin Health (LIBRA) score 2
Time Frame: 1 year
1-year change in the Lifestyle for BRAin Health (LIBRA) score 2. This is a weighted score of fifteen lifestyle-related risk factors that are proven to be associated with increased dementia risk. Higher score means a greater risk for dementia. Scored from -6.1 to 25.8 (absolute weight).
