Long-term physical activity (specifically aerobic exercise) promotes neuroplasticity and cognitive health in aging adults by upregulating Brain-Derived Neurotrophic Factor (BDNF), increasing hippocampal volume, and reducing neuroinflammation.

Engage in regular moderate aerobic exercise (e.g., brisk walking, cycling) at least 3 times per week for 12 months or more. This specific protocol has been shown to increase hippocampal volume and reverse 1-2 years of age-related brain loss, directly supporting memory and executive function.

GoodSupportsHIGH confidence
Indeed, a multiplicity of studies has demonstrated relationships between lifestyle factors, brain structure and function, and cognitive function in aging adults. For example, physical activity and diet modulate common neuroplasticity substrates (neurotrophic signaling, neurogenesis, inflammation, stress response, and antioxidant defense) in the brain...
