Cognitive health is the integrated capacity of attention, working memory, executive function, processing speed, and emotional regulation.
Mechanism: A function of cerebrovascular health, neuroinflammation, sleep architecture, neurotransmitter balance, and ongoing neural challenge. Maintained by the same fundamentals as physical health, plus deliberate cognitive demand.
Use case: Resistance training, Zone 2 cardio, sleep optimization, omega-3s, B-vitamins, novel skill acquisition, social engagement. Cognitive testing (MoCA, CNS Vital Signs) annually after 55.
Caveats: Brain games don't transfer outside the game. Real cognitive demand (language, instrument, complex problem solving) does.
