What is the Origin of Resilience against Mental Fatigue?

This concept is derived from cognitive psychology and stress physiology, focusing on the ability of the brain to resist a decline in function. The term "resilience" highlights the adaptive capacity of the neuro-endocrine system to maintain stability under perturbation. It provides a functional endpoint for assessing the efficacy of interventions aimed at optimizing brain health and stress management.

What is the Mechanism of Resilience against Mental Fatigue?

Resilience against mental fatigue is mechanistically supported by robust cerebral blood flow, which ensures consistent glucose and oxygen delivery, and by efficient clearance of metabolic waste products. Hormonally, a well-regulated cortisol diurnal rhythm prevents chronic exposure of the hippocampus to excessive glucocorticoids, which can impair cognitive function. The ability to maintain stable Neuro-Cognitive Substrate Levels is also paramount, ensuring that the necessary precursors for sustained neurotransmission are readily available.

Resilience against Mental Fatigue

Meaning

The physiological and psychological capacity of an individual to sustain high levels of cognitive performance, attention, and executive function over prolonged periods despite continuous mental load or exposure to chronic stressors. This resilience is intimately linked to the stability of neurotransmitter balance, the efficiency of cerebral energy metabolism, and the appropriate regulation of the HPA axis. It is a crucial measure of neuro-endocrine health and overall functional longevity.
