NCT07457138

Brief Summary

The goal of this multicenter prospective observational cohort study is to better understand the clinical, neuropsychological, and biological characteristics of individuals attending Brain Health Services (BHS) in the Lombardy region. The study focuses on adults with subjective cognitive decline (SCD), functional cognitive disorder (FCD), or "well worried" individuals without objective cognitive impairment. The main questions it aims to answer are:

  • What clinical, cognitive, and biological differences exist between individuals who are positive versus negative for Alzheimer's disease (AD) plasma biomarkers (p-tau217) at baseline?
  • What factors predict positivity to AD biomarkers at baseline?
  • How does communication of biomarker results (risk disclosure) affect psychological well-being shortly after receiving results?
  • What factors predict longitudinal changes in AD biomarkers over 5 years?
  • Do baseline biomarkers predict the development of mild cognitive impairment (MCI) or dementia during follow-up? Participants will:
  • Undergo standard clinical evaluation at their local BHS
  • Provide blood samples for plasma biomarker analysis (e.g., p-tau217, GFAP, NfL, ApoE)
  • Undergo neuropsychological testing and cognitive screening
  • Complete questionnaires assessing psychological impact and risk perception (before and after biomarker disclosure)
  • Undergo additional center-specific procedures when clinically indicated (e.g., MRI, lumbar puncture, polysomnography)
  • Be followed annually for 5 years The study plans to enroll approximately 1000 participants across multiple BHS in Lombardy and will follow them for a total duration of 7 years. The results will help clarify the role of biomarkers in early cognitive complaints and support the development of preventive strategies within BHS.

Outcome Measures

Primary Outcomes (1)

  • Clinical, neuropsychological, and biological patterns associated with AD plasma biomarker positivity at baseline

    Identification of multivariate patterns (e.g., principal component analysis and clustering methods) differentiating individuals positive versus negative for Alzheimer's disease plasma biomarker (p-tau217) at baseline, based on demographic, clinical, neuropsychological, radiological, and biological variables.

    Baseline (first visit at Brain Health Service)

Secondary Outcomes (3)

  • Psychological impact of biomarker disclosure at1 week

    Baseline (pre-disclosure) and 1 week after biomarker disclosure

  • Predictors of AD plasma biomarker positivity at baseline

    Baseline

  • Predictors of longitudinal changes in AD biomarkers

    Baseline through 5 years follow-up

Other Outcomes (2)

  • Predictors of conversion to MCI or dementia

    Baseline through 5 years follow-up

  • Predictive performance of plasma biomarkers for AD diagnosis

    Baseline
