Cognitive Function Speed

Meaning

Cognitive function speed quantifies the rate at which an individual can process information, execute mental tasks, and react to stimuli, representing a core metric of neurological efficiency. This measure reflects the integrity of neural pathways and the efficiency of neurotransmitter signaling within the central nervous system. Hormonal balance, particularly involving thyroid hormones, estrogen, and testosterone, is critically linked to maintaining optimal synaptic plasticity and rapid information processing. Declines in this speed often precede noticeable cognitive impairment, making it a key longevity biomarker.
