PENSA+: Extended Follow-up of a Multimodal Lifestyle Intervention to Prevent Cognitive Decline in APOE-ε4 Carriers

Sponsor: Barcelonabeta Brain Research Center, Pasqual Maragall Foundation

Summary

PENSA+ is a 5-year follow-up study of participants who previously completed the PENSA clinical trial (NCT03978052), which evaluated an intensive multimodal lifestyle intervention, with or without epigallocatechin gallate (EGCG), in APOE-ε4 carriers with subjective cognitive decline, a population at increased risk of developing Alzheimer's disease. The purpose of this study is to determine whether the cognitive, biological, and lifestyle benefits observed after the original intervention are maintained over the long term. Researchers will evaluate cognitive performance, the incidence of mild cognitive impairment, dementia risk, brain imaging, blood biomarkers, physical fitness, lifestyle behaviors, and psychosocial factors approximately five years after completion of the intervention. The study will also investigate the biological and behavioral mechanisms associated with sustained cognitive benefit, identify participant characteristics associated with better long-term outcomes, evaluate the long-term cost-effectiveness of the intervention using healthcare utilization data, and explore whether lifestyle changes have influenced participants' study partners. No new intervention will be administered as part of this follow-up study.
