METformin and FINGER Intervention to Prevent Cognitive Impairment and Disability in Older Adults at Risk for Dementia

Plain-language summary

This study investigates whether the healthy-lifestyle FINGER program combined with the drug metformin can help prevent cognitive impairment in older adults at risk for dementia. It is enrolling people aged 60-79 who have a high dementia risk score and cognitive performance at or slightly below the level expected for their age. Sponsored by Imperial College London, the study is in Phase 2 and is still recruiting participants.

  2. Cardiovascular Risk Factors, Aging and Dementia (CAIDE) Risk Score ≥6 points.
  3. Cognitive performance at the mean level or slightly lower than expected for age according to local population norms based on the Montreal Cognitive Assessment (MoCA) test and the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) verbal learning test.
  4. Proficiency in the local language (English, Finnish or Swedish)
* Inclusion criteria for metformin/placebo treatment (only for participants in the FINGER 2.0 multimodal lifestyle-based intervention arm)

  1. No diagnosed diabetes or known contraindications to metformin treatment.

Exclusion Criteria:

* Main exclusion criteria (all participants)

  5. Any other condition affecting safe engagement in the intervention (e.g., malignant disease, major depression, symptomatic cardiovascular disease, revascularisation within the previous year).
  6. Severe loss of vision, hearing, or communicative ability; conditions preventing cooperation.
  7. Coincident participation in the active phase of another intervention trial.
