Seasonal affective disorder is a mental health condition that is triggered by the changing of the seasons. This condition is a subtype of major depressive disorder and bipolar disorder. Major depressive disorder is characterized by prolonged sadness and a general lack of interest, while bipolar disorder is characterized by similar depressive episodes alternating with periods of abnormally high energy and activity (hypomania or mania). People with seasonal affective disorder have signs and… Expand
Seasonal symptoms in bipolar and primary care patients.
TLDR
Seasonal changes, most notably winter hypersomnia, should be identified in patients with BAD and these symptoms may respond to treatments such as light therapy that are used in recurrent winter depression. Expand
Cognitive Vulnerability to Depression in Seasonal Affective Disorder: Predicting Mood and Cognitive Symptoms in Individuals with Seasonal Vegetative Changes
Research indicates that seasonal fluctuations in vegetative functions (e.g., sleep, appetite, and energy) occur to varying degrees in the general population and a large fluctuation in vegetativeExpand
Psychological therapies for preventing seasonal affective disorder.
TLDR
No controlled studies on use of psychological therapy to prevent SAD and improve patient-centred outcomes in adults with a history of SAD are found. Expand
Season-independent cognitive deficits in seasonal affective disorder and their relation to depressive symptoms
TLDR
Novel evidence is presented that in SAD individuals, working memory, cognitive processing- and motor speed is not only impaired in the winter but also in the summer, which suggests that certain cognitive impairments are SAD traits. Expand
Psychological therapies for preventing seasonal affective disorder.
TLDR
The included RCT compared preventive use of mindfulness-based cognitive therapy (MBCT) with treatment as usual (TAU) in participants with a history of SAD, and the incidence of a new depressive episode in the upcoming winter was similar in both groups. Expand
Second-generation antidepressants for preventing seasonal affective disorder in adults.
TLDR
Overall, moderate-quality evidence indicates that bupropion XL is an efficacious intervention for prevention of recurrence of depressive episodes in people with a history of SAD. Expand
Second-generation antidepressants for preventing seasonal affective disorder in adults.
TLDR
Overall moderate-quality evidence indicates that bupropion XL is an efficacious intervention for prevention of recurrence of depressive episodes in patients with a history of SAD. Expand
Light therapy for preventing seasonal affective disorder.
TLDR
To assess the efficacy and safety of light therapy in preventing SAD and improving patient-centred outcomes among adults with a history of SAD, this review focuses on light therapy as a preventive intervention. Expand
Melatonin and agomelatine for preventing seasonal affective disorder.
TLDR
No available methodologically sound evidence indicates that melatonin or agomelatine is or is not an effective intervention for prevention of SAD and improvement of patient-centred outcomes among adults with a history of S AD. Expand

Seasonal affective disorder. A description of the syndrome and preliminary findings with light therapy.
TLDR
Preliminary studies in 11 patients suggest that extending the photoperiod with bright artificial light has an antidepressant effect and sleep recordings in nine depressed patients confirmed the presence of hypersomnia and showed increased sleep latency and reduced slow-wave (delta) sleep. Expand
A follow-up study of seasonal affective disorder.
TLDR
Diagnostic criteria for seasonal affective disorder need to be further refined, possibly restrictively, if they are to be used to predict the future course of seasonal illness. Expand
Prevalence of seasonal affective disorder in Iceland.
TLDR
The prevalence of SAD and S-SAD was lower in Iceland than on the East Coast of the United States, in spite of Iceland's more northern latitude, which is unexpected since the prevalence of these disorders has been found to increase in more northern latitudes. Expand
Prevention of winter seasonal affective disorder by bright-light treatment.
TLDR
Bright light can be successfully administered as prophylactic treatment for the prevention of winter SAD by being given well in advance of the emerging symptoms. Expand
Prevalence of seasonal affective disorder at four latitudes
TLDR
Prevalence rates of winter SAD and subsyndromal SAD were found to be significantly higher at the more northern latitudes, while no correlation was found between latitude and summer SAD. Expand
Phototherapy in individuals with and without subsyndromal seasonal affective disorder.
TLDR
It is found that bright artificial light did not alter mood and behavior in controls and in contrast, individuals with subsyndromal seasonal affective disorder responded favorably to treatment with bright environmental light. Expand

TLDR
Most research evidence to date supports the efficacy of phototherapy in the treatment of SAD, however, considerable controversy remains concerning its mechanism of action and the underlying pathophysiology of the disorder. Expand
Effects of rapid tryptophan depletion in patients with seasonal affective disorder in remission after light therapy.
TLDR
Investigating the effects of rapid tryptophan depletion in patients with seasonal affective disorder that was in clinical remission after light therapy suggests that the therapeutic effects of bright light in SAD may involve a serotonergic mechanism. Expand
Epidemiological findings of seasonal changes in mood and behavior. A telephone survey of Montgomery County, Maryland.
TLDR
It is apparent from this study that seasonal affective disorder represents the extreme end of the spectrum of seasonality that affects a large percentage of the general population and might provide valuable insight into pathogenesis, treatment, and prevention of affective illness. Expand
Treatment of Seasonal Affective Disorder: A Review
TLDR
There are several well-studied, effective treatments for SAD, including light therapy and medications, but further research must be done to demonstrate sustained treatment response over time, to clarify the intensity-response relationship of light therapy, and to assess combination treatments.
