Cognitive reserve is a concept that involves individual abilities to cope with changes, and it can help predict and prevent cognitive decline and Alzheimer's disease. By maintaining environmental enrichment, efficient synaptic plasticity mechanisms can protect cognitive reserve, keeping repair mechanisms effective and promoting successful aging.
Cognitive reserve is originally an epidemiological concept that encompasses individual abilities to cope with changes. It is considered the result of a balance between processes of cellular damage and repair, and its description raised much interest in predicting and preventing cognitive decline in aging and Alzheimer's disease (AD). In this study, we discussed the concept of cognitive reserve considering the recent definition of AD as a biological continuum and suggest that the protection of cognitive reserve may result from efficient synaptic plasticity mechanisms. Despite pathological changes of AD appearing very early during life, long before the onset of cognitive symptoms, different variables act together to keep repair mechanisms effective guaranteeing successful aging if environmental enrichment is maintained.
