Definition: What is cognitive reserve?
Cognitive reserve refers to the brain’s ability to withstand and compensate for age-related changes and neurological damage. It is a concept that suggests some individuals are better able to maintain cognitive function and delay the onset of cognitive decline or dementia, despite the presence of brain pathology.Research has shown that individuals with higher cognitive reserve have a reduced risk of developing cognitive impairment or dementia. This resilience is believed to be due to the brain’s ability to adapt and reorganize itself in response to damage or decline.

Cognitive reserve is influenced by various factors, including education level, occupational complexity, social engagement, and intellectual stimulation. These factors contribute to the development of a cognitive reserve by building and strengthening neural connections in the brain.
Having a higher cognitive reserve can result in delayed onset of symptoms and slower progression of cognitive decline in individuals with conditions such as Alzheimer’s disease. It can also improve cognitive performance and enhance the ability to cope with brain injuries or other neurological disorders.

Understanding cognitive reserve is important as it highlights the potential for interventions and lifestyle changes that can enhance brain health and promote cognitive resilience. By engaging in activities that stimulate the brain, such as learning new skills, staying socially active, and maintaining a healthy lifestyle, individuals can potentially increase their cognitive reserve and reduce the risk of cognitive decline.
