Sometimes when you’re stuck in your own stuff, you forget that the world is changing outside you. You zoom into what’s going wrong and that narrow focus prevents you from seeing what’s going right. Like this week, I learned that we’re predisposed to forgive, which one of four personality types I might be, and the innovative ways colleges are trying to reach students grappling with mental illness. It reminded me things are always improving. We’re getting closer to understanding ourselves and each other a little better. Isn’t that exciting? I hope you enjoy this sample of psychology offeri...

Abstract Light profoundly affects the behavior and physiology of almost all animals, including humans. One such effect in humans is that the level of illumination during the day positively contributes to affective well-being and cognitive function. However, the neural mechanisms underlying the effects of daytime light intensity on affect and cognition are poorly understood. One barrier for progress in this area is that almost all laboratory animal models studied are nocturnal. There are substantial differences in how light affects nocturnal and diurnal species, e.g., light induces sleep in nocturnal mammals and wa...

Seasonal affective disorder (SAD) is a recurrent illness affecting around 5% of the population at temperate latitudes (Rosenthal et  al., 1984; Lewy et al., 2009). Most frequently, patients experience depressive symptoms during fall and winter, with full remission to normal mood or switch into hypo/mania during spring and summer (Lam et al., 1995; Zauderer and Ganzer, 2015). This predominant manifestation of SAD is called win ter depression (Magnusson and Boivin, 2003).

Authors: Cools O, Hebbrecht K, Coppens V, Roosens L, De Witte A, Morrens M, Neels H, Sabbe B Abstract INTRODUCTION: A seasonal affective disorder (SAD) is a subtype of unipolar and bipolar major depressive disorders. It is characterized by its annual recurrence of depressive episodes at a particular season, mostly seen in winter and is responsible for 10-20% of the prevalence of major depressive disorders. Some pathophysiological hypotheses, such as the phase delay and the monoamine depletion hypotheses, have been postulated but the exact cause has not been fully unraveled yet. Studies on treatment for SAD in the l...

Authors: Wirz-Justice A, Ajdacic V, Rössler W, Steinhausen HC, Angst J Abstract The prevalence of autumn/winter seasonality in depression has been documented in the longitudinal Zurich cohort study by five comprehensive diagnostic interviews at intervals over more than 20 years (N = 499). Repeated winter major depressive episodes (MDE-unipolar + bipolar) showed a prevalence of 3.44% (5× more women than men), whereas MDE with a single winter episode was much higher (9.96%). A total of 7.52% suffered from autumn/winter seasonality in major and minor depressive mood states. ...

Abstract Identifying objectively measurable seasonal changes in 24-h activity patterns (rest-activity rhythms or RARs) that occur in seasonal affective disorder (SAD) could help guide research and practice towards new monitoring tools or prevention targets. We quantified RARs from actigraphy data using non-parametric and extended cosine based approaches, then compared RARs between people with SAD and healthy controls in the summer (n = 70) and winter seasons (n = 84). We also characterized the within-person seasonal RAR changes that occurred in the SAD (n = 19) and control (n =&n...

Seasonal affective disorder (SAD), first described in 1984 (Rosenthal, 2009), is not considered to be a separate and unique mood disorder, but rather to be a specifier of major depressive disorder (Lurie et al. 2006). The overall prevalence of SAD is thought to range from 0% to 9.7% (Lurie et al. 2006). This estimate varies based on the specific population being studied and whether the disorder is diagnosed by a screening questionnaire or a more rigorous clinical interview (Lurie et al. 2006). The clinical presentation of SAD comprises the following (Rosenthal, 2009): patients are predominantly women who become regularly d...
