A Novel, Brief, Fully Automated Intervention to Extend the Antidepressant Effect of a Single Ketamine Infusion: A Randomized Clinical Trial

Dr. Rebecca Price

Depression is one of the most prevalent and costly mental health conditions. Though effective treatments have been available for decades, remission rates are low, relapse rates are high, and disorder prevalence rates remain notably consistent or increased, with only 12.7% of patients receiving minimally adequate treatment. In recent years, two potential breakthroughs have ignited hopes for turning a corner in the...

New Research: Self-reported Sleep and Circadian Characteristics Predict Alcohol and Cannabis Use

Although multiple specific sleep characteristics can contribute to risk factors for alcohol and cannabis use and related problems in later adolescence and young adulthood, most research has examined a limited range of sleep characteristics within a narrow age span. In a recent study, Pitt Psychiatry investigators including Brant Hasler, PhD (Associate Professor of Psychiatry, Psychology, and Clinical and...

The Center for Sleep and Circadian Science Hosts Outstanding Three-Day Training and Research Innovation Event

An Outstanding Program of Sleep Research Training and Innovation

Over the course of three days in early November, the Center for Sleep and Circadian Science hosted the Fall 2021 SWIM (Sleep and Circadian Workshop on Indispensable Methods) Workshop and the Center’s 6th Annual Sleep and Circadian Science Research Day. SWIM is an intensive training program on state-of-the-art sleep and circadian science research methodologies. Twenty-nine trainees from across the US participated in...
