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.
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.
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.
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.
Talk 0871- Growing Up with a Depressed Family Member is Associated with Insufficient Sleep and Moderates the Relationship between Insufficient Sleep and Mental Health.
H.Y. Katy Siu, Subhajit Chakravorty MD, Michael L. Perlis PhD, and Michael A. Grandner PhD
Growing up with a family member who is depressed makes it more likely that you will have sleep problems as an adult, even controlling for your own mental health. Also, growing up with a depressed family member strengthens the relationship between insufficient sleep and mental health.
Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $4.9 billion enterprise.
The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 17 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $409 million awarded in the 2014 fiscal year.
The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania -- recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report; Penn Presbyterian Medical Center; Chester County Hospital; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Chestnut Hill Hospital and Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.
Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2014, Penn Medicine provided $771 million to benefit our community.
