Introduction: Subjective cognitive complaints may be a signature of preclinical
stage Alzheimer’s disease. However, the link between subjective cognitive and
non-cognitive complaints and brain alterations remains unclear.
Methods: The relationship between cognitive and non-cognitive complaints and
brain biomarkers, measured by structural magnetic resonance imaging, was
investigated in 2056 participants of the MEMENTO cohort of outpatients, who were
dementia-free at baseline. We assessed whether the cognitive status at inclusion
or the presence of the apolipoprotein E gene variant (APOE) ε4 could modulate the
association between the intensity of complaints and brain lesions.
Results: Smaller hippocampal volume was associated with higher memory complaints
and discomfort in daily life. In APOE ε4 carriers, smaller whole-brain white
matter and gray matter volumes and gyrification indices in several regions of
interest of the parietal and temporal lobes, in the entorhinal and the
para-hippocampal gyrus, were associated with higher memory complaint score.
Conclusions: The intensity of subjective complaints in not only memory but
discomfort in daily life was associated with brain degeneration markers. The
presence of APOE ε4 modulated the relationships between subjective memory
complaints and brain alterations.
