Brain Training That Works: Novelty, Rest, and Exercise to Boost Cognition
Neurologist says the brain adapts like muscles: true cognitive growth comes from novel, challenging tasks paired with adequate rest. Adult neuroplasticity persists, with learning languages, dancing, or music increasing brain volume and connectivity; breaks and sleep—especially REM sleep—are crucial for clearing waste, repairing tissue, and consolidating memories. Exercise raises BDNF and blood flow, protecting cognition. Overdoing mental work causes neural fatigue, so balance effort with breaks and varied activities to maintain cognitive resilience.
