Key result
Total sleep deprivation in healthy adults significantly blunted the cortisol awakening response and decreased [11C]raclopride binding in the basal ganglia, reflecting altered stress and dopaminergic regulation.
Why the study?
Does total sleep deprivation induce neurophysiological, cognitive, and endocrine changes in healthy adults?

Hypothesis-generating in healthy adults; leaves open clinical relevance of altered stress and dopaminergic responses to sleep deprivation.
Does total sleep deprivation induce neurophysiological, cognitive, and endocrine changes in healthy adults?
Absolute Event Rate: 511.5% vs 886.58%
p-value: p=0.022
Total sleep deprivation in healthy adults leads to reduced cognitive functioning, blunted cortisol response, and altered dopamine binding, indicating the involvement of adaptive biological systems to sustain wakefulness.
Klumpers et al. (2015) studied Healthy adults (n=12). Total sleep deprivation vs. Baseline (regular night of sleep) was evaluated on Cortisol awakening response (CAR) area under the curve to ground (AUCG) (p=0.022). Total sleep deprivation in healthy adults significantly blunted the cortisol awakening response and decreased [11C]raclopride binding in the basal ganglia, reflecting altered stress and dopaminergic regulation.
