Cognitive reserve

Cognitive reserve is a theoretical construct, its something that scientists believe to exist because it explains a number of associations.

Cognitive reserve seems to be built from a lifetime exposure to cognitive stimulation. However scientists can’t directly measure or observe this, but they think it induces changes to the structure and function of the brain to make it more resilient and more flexible.

To increase cognitive reserve, you need to challenge your brain with new learning, learning of new knowledge or skills on a regular basis.
