How to Improve Your Memory & Cognitive Function at Any Age | Dr. Alan Castel

Memory is reconstructive, not a perfect recording, and cognitive decline in old age is not inevitable. While some memory systems naturally change, "superagers"—individuals who maintain exceptional cognitive function—demonstrate that curiosity, physical activity, social connection, and a positive mindset about aging can preserve and even improve mental capacity across the lifespan.
-
Memory reconstruction — Memory is a mental representation of the past that is never perfectly accurate. Because our brains reconstruct memories upon retrieval, they are prone to contamination and error .
-
Learning through mistakes — Making errors is essential for deeper retention.
- Trying to draw an object from memory forces the brain to engage more deeply than passively looking at it .
- Corrective feedback after a failure cements knowledge better than simply being shown the correct answer initially .
-
Habit breaking — We often stop noticing our surroundings because of habituation. Deliberately changing routines, like switching seats in a classroom, forces the brain to re-engage with the environment .
-
Physical activity — Regular cardiovascular exercise, specifically walking, significantly impacts brain structure.
- It can increase the volume of the hippocampus, a brain area critical for declarative memory .
- It helps offset cognitive decline, often more effectively than purely stretching or low-intensity movement .
-
Importance of balance — Balance is a critical, trainable skill that deteriorates with age. Maintaining it is vital because falls often lead to inactivity, which accelerates the shrinking of brain regions tied to memory .
-
Beliefs about aging — Your mindset regarding getting older functions as a self-fulfilling prophecy. A more positive outlook on one's own aging process is linked to better health outcomes and longevity .
-
Social and emotional health — "Superagers" often possess a high sense of purpose and stay socially connected. They remain curious and continue seeking new information, which keeps neural pathways active .
