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...

New Research in Psychological Medicine and Human Brain Mapping on the Effects of Disrupted Sleep and Early Life Stress in Young People

New Research on the Effects of Disrupted Sleep and Early Life Stress in Young People

Psychological Medicine : Experimentally Imposed Circadian Misalignment Alters the Neural Response to Monetary Rewards and Response Inhibition in Healthy Adolescents During adolescence, circadian rhythm and natural sleep and wake times shift later, which can conflict with early school-start times. This incongruence commonly results in circadian misalignment (mismatch between the behavioral sleep-wake schedule and...

Department Faculty Highlight the Role of Adolescent Sleep and Circadian Rhythm Disruptions in Risk of Substance Use Disorders 

Logan et al Biological Psychiatry 2018

Sleep and circadian rhythms, the 24-hour cycles of the body’s physiological processes, are important components of health. Likewise, disruptions in these systems are linked to a number of health conditions, including substance abuse. The developmental changes in sleep and circadian rhythms that occur during adolescence leave teenagers particularly vulnerable to addiction. A review recently published in the journal...
