Sleep changes are a major feature of the ageing process, and sleep disturbances are increasingly recognized as a risk factor for cognitive decline and Alzheimer’s disease (AD). However, the brain mechanisms underlying this association are still unclear. The objective of this thesis was to deepen our understanding about brain structural, functional and molecular correlates of the main objective sleep changes in ageing, and to assess the potential links with cognitive performance. Our results demonstrate that the fragmentation of the first sleep cycles and the alteration of slow wave activity, are associated with reduced gray matter metabolism, perfusion and/or volume in fronto-cingulate and hippocampal areas. Moreover, sleep-disordered breat...
