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

Prioritizing a few meaningful activities preserves performance because concentrating limited cognitive and physical resources on what matters compensates for declines and maintains subjective well-being.

Maintaining social connection and generativity preserves cognitive and mental health because interaction and purpose provide novel stimulation and motivation that drive activity, learning, and emotional well-being.

Simple balance exercises reduce fall risk and support brain health because they train visual, vestibular, and proprioceptive integration and improve neuromuscular control that stabilizes movement.

Strong habits can cause prospective memory failures because automatic scripts skip deliberative steps, so when a rare change occurs the dominant routine executes and the intended action is omitted.

Getting up and performing the action instead of just being told improves everyday memory because embodied interaction creates situational cues that are encoded more robustly and later trigger retrieval when needed.

Picking someone from a lineup can replace your original memory because repeatedly retrieving and rehearsing the identified face re-encodes it into the trace, overwriting or integrating the real perceptual details.

High emotional arousal makes memories more likely to be retained but can distort their accuracy because amygdala-driven salience strengthens consolidation while also biasing reconstruction and increasing contamination risk.

Varying where and how you learn improves encoding because novel contexts supply distinct cues and prevent overlap between similar episodes, which reduces interference and makes retrieval easier.
