O072 Episodes of drowsiness present during cognitively demanding tasks

Abstract Introduction Insufficient sleep is associated with impaired performance in cognitive tasks and executive functioning. Adolescence a time of increasing autonomy lifestyle changes, where social, educational, work demands often impact on opportunity. The habitual short opportunity functioning poorly understood. We examined the difference EEG-based alertness during low high load restricted young adults. Methods Ninety-nine habitually adults (M=20.65, SD=1.91, 73% female) participated study. (F4-M1, O2-M1) was under two conditions: (1) load; simulated slow drive (2) weekly activity mapping task. A novel model predicted as continuous function EEG power beta, alpha, theta, delta frequency bands. Model output 1 indicates (i.e., wake), while values approaching zero indicate reductions alertness. Statistical significance assessed by two-tailed t-test (unequal variance), effect size reported Cohen’s D. Results Mean were significantly (p<0.0001) lower driving task (0.16, 95%CI=0.12-0.19) compared to (0.92, 0.87-0.97), substantial (D=3.9). Conclusions This study demonstrates that are less alert demands, even though we tested (simulated drive) represents real-world risk. In contrast, these individuals show elevated levels cognitively demanding despite absence Further investigating potential mitigating effects through modulation may reveal simple health recommendations
