SAD, otherwise known as seasonal affective disorder, is a type of depression that usually occurs during winter time. Over the last few years SAD lamps have become more popular with people trying to remedy the problem, so should you invest in one this winter? Dr Dawn Harper issues her advice.

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...

Brain monoamine oxidase A in seasonal affective disorder and treatment with bright light therapy, Published online: 21 September 2018; doi:10.1038/s41398-018-0227-2Brain monoamine oxidase A in seasonal affective disorder and treatment with bright light therapy

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).

We have recently shown that the emergence and severity of seasonal affective disorder (SAD) symptoms in the winter is associated with an increase in cerebral serotonin (5-HT) transporter (SERT) binding. Intriguingly, we also found that individuals resilient to SAD downregulate their cerebral SERT binding in the winter. In the present paper, we provide an analysis of the SERT- and 5-HT dynamics as indexed by 5-HT4 receptor (5-HT4R) binding related to successful stress coping. We included 46 11C-DASB positron emission tomography (PET) scans (N  = 23, 13 women, age: 26 ± 6 years) and 14 11C-SB207145 PET s...

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...

When my son Dan was dealing with severe OCD, he would often be awake all night, pacing throughout the house. It was not unusual for me to get up in the morning and find him fast asleep on the living room floor, or wherever else he happened to finally collapse from exhaustion. Even when his symptoms began to improve, he still could not seem to fall asleep at a normal hour and would be awake until 4:00 am or so. Not surprisingly he’d then sleep half the day away. His sleep cycle was all out of whack. It turns out that this abnormal sleep pattern is not unusual in those with OCD and has warranted the attention of resea...
