Cognitive reserve is the reason that one person with significant Alzheimer's pathology continues to function independently while another with the same level of pathology is severely impaired. It is the accumulated neural capital built through education, bilingualism, occupational complexity, social engagement, and lifelong mental stimulation, and it does not prevent brain pathology but provides the compensatory infrastructure that allows the brain to tolerate it. This fully referenced article explores what cognitive reserve is, how it develops, why it is unevenly distributed, and what the implications are for a society that has made it a function of socioeconomic privilege.
