Cognitive Fatigue

Meaning

Cognitive fatigue is a profound, subjective state of mental exhaustion characterized by a temporary reduction in the capacity for focused attention, complex problem-solving, and executive function. Individuals experience a palpable decline in their ability to process information efficiently, often resulting in impaired concentration and increased difficulty initiating tasks. This is distinct from physical tiredness, representing a failure of sustained mental effort that significantly impacts daily function and well-being.
