12PM Oral Presentation 242 - Neurobehavioral and Physiological Effects of High Cognitive Workload and Chronic Sleep Restriction Namni Goel, PhD, Marcia Braun, PhD, and David Dinges, PhD This study provides the first experimental evidence that the amount of cognitive workload a person experiences produces negative effects such as fatigue and sleepiness independent of sleep loss.

4 PM Poster Presentation 326 - Are those with more physically demanding jobs more likely to exhibit short/long sleep duration? Holly E. Barilla, Charles Corbitt, Subhajit Chakravorty, MD, Michael Perlis, PhD, and Michael A. Grandner, PhD Those with jobs that are more manual labor and physically demanding are more likely to be short sleepers. This could be one of the social/environmental factors leading to insufficient sleep.

12:15 PM Oral Presentation 243 - Effects of Cognitive Workload on Sleep Physiology under Sleep Restricted and No Sleep Restricted Conditions Takashi Abe, PhD, Namni Goel, PhD, and David Dinges, PhD This study indicates that people with jobs or daily tasks that require higher cognitive workload can experience difficulties falling asleep initially, but stay asleep longer before awakening, independent of sleep loss.

4 PM Poster Presentation 267 - Sleep Duration as a Predictor of Moderate/High (vs Low) Suicide Risk in Insomnia Linden Oliver, Andrea Segal, Florda Priftanji, Michael Grandner, PhD, and Michael Perlis, PhD

Insomnia is a newly-identified risk factor for suicidality. Among patients with insomnia, short sleepers are more likely to report suicidal ideation. However, in those with some suicide risk, the likelihood of being high risk (versus low risk) decreased by 72 percent for every hour of sleep that person reported getting at night.

Poster Presentation 288 - Suicidal Ideation Associated with Insomnia Symptoms and Sleep Duration. H.Y. Katy Siu, Linden Oliver, Subhajit Chakravorty, MD, James Findley, PhD, Michael Perlis, PhD, and Michael Grandner, PhD In a national-level sample, insomnia and short/long sleep were associated with increased suicidal ideation. This is the first time that insomnia is established as a risk factor for suicide at the national level.
