Resistance to Mental Fatigue

Meaning

Resistance to mental fatigue is the sustained ability of the central nervous system to maintain high-fidelity cognitive function, attention, and processing speed over prolonged periods of demanding intellectual effort without a significant decrement in performance. This resilience is a direct consequence of robust brain cellular integrity, efficient energy metabolism, and optimized neurotransmitter cycling. It is the antithesis of ‘brain fog’ and a key characteristic of superior intellectual horsepower. Clinical protocols aim to enhance this resistance to maintain consistent high performance.
