Cognitive Effects of Stress-Related Exhaustion
Summary
Stress-related exhaustion manifests as a marked decline in cognitive performance, affecting memory, attention, executive control and processing speed. Individuals often report difficulties in concentrating, retrieving information and sustaining mental effort, which can persist long after the acute stressor has abated. Research indicates that these deficits are not solely subjective complaints but are corroborated by objective testing and neuroimaging findings. Impairments appear most pronounced in tasks requiring rapid information updating, complex problem-solving and sustained attention. Concurrently, structural alterations in subcortical regions implicated in cognitive control, notably the striatum, have been linked to mental fatigue and its impact on working memory. The persistence of cognitive symptoms can impede daily functioning, reduce work capacity and diminish quality of life, underscoring the need for early detection, tailored interventions and rehabilitative strategies that address both psychological and neural dimensions of exhaustion.
