What is Seasonal Affective Disorder


First described in 1984 by Norman Rosenthal and his colleagues, Seasonal Affective Disorder (SAD) is a depression condition with a seasonal component.

SAD isn’t a distinct diagnosis on its own but acts as a specifier within the diagnosis of major depressive disorder and bipolar disorder. If you have depression or bipolar disorder that follows a seasonal pattern, it might be diagnosed as SAD (Jacobson et al., 1987).

It’s crucial to understand that, like all mental health diagnoses, there can be confusion due to overlapping symptoms. Some professionals even doubt its existence. However, from my own experience in practice, I firmly believe in its validity. Recognizing this component is essential as it might guide the approach of the therapist or doctor treating you.

One clear definition of seasonal affective disorder is a form of clinical depression that recurs annually, starting in the fall and winter and concluding in the spring and summer (Rohan, 2009).

What is the Criteria for Seasonal Affective Disorder?

While everyone exhibits seasonal variations in behavior and mood – feeling sluggish or blue in the winter, for instance, and more energized in spring and summer – these patterns don’t necessarily equate to SAD. To be diagnosed with SAD, you must first have depression or bipolar disorder. It’s also worth noting that many experience sub-clinical symptoms (significant but not enough for a diagnosis), often termed “Winter Blues.” If this resonates, seeking help is advisable. Early therapy can be more effective!

When will a doctor tell you you have a Seasonal Affective Disorder?

  • You experience depression every year during the same season.
  • Your depressive state ends after the season.
  • This pattern persists for two years.
  • Even if depression occurs at other times, it predominantly surfaces in one particular season (APA, 1994).

How Patterns Help Us Determine Seasonal Affective Disorder

Typically, seasonal depressive disorder manifests as winter depression, starting in the fall/winter. However, there’s another form known as summer depression, which begins in the spring and early summer. Each type has its distinct symptom set.

Winter SAD often presents with symptoms not common in general depression: daytime drowsiness, cravings for carbohydrates, weight gain, fatigue, and excessive sleepiness (Jacobson et al., 1987).

General Signs and Symptoms of Seasonal Affective Disorder

Common signs and symptoms of SAD include anxious feelings, guilt, irritability, difficulty concentrating, constant bad mood, decreased libido, increased appetite, social isolation, and even suicidal thoughts. It is more prevalent in women and living further from the equator may increase the risk of developing SAD, according to research.

What Causes Seasonal Affective Disorder?

Theories regarding the causes of SAD revolve around melatonin, serotonin, vitamin d, and alterations in the circadian rhythm (Jacobson, 1987). The success of light therapy in treating SAD points toward specific mechanisms that should be studied to ascertain the condition’s origins.

Risk Factors of Seasonal Affective Disorder

Seasonal Depression Risk Factors include:

  • History of Depression
  • Gender
  • Geography
  • Family History


 Facts About Seasonal Affective Disorder

  • Women are four times more likely than men to be affected by SAD (Jacobson, 1987).
  • Women with SAD often experience more severe PMS, suggesting a potential hormonal link (Portella et al., 2006).
  • Studies indicate that SAD is more prevalent at higher altitudes and tends to last longer there (Mersch et al., 1999).
  • Children, too, can suffer from SAD.
  • Most SAD sufferers also grapple with weakened immune systems (Leu et al., 2001).
  • Individuals above the age of 65 are less prone to SAD.
  • Bulimia Nervosa, another diagnosis with a seasonal component, often co-occurs with SAD (Lam et al., 2006).
  • SAD’s prevalence is lowest in Florida and highest in Alaska.

Relationship between ADHD and Seasonal Affective Disorder:

Individuals with ADHD may be more susceptible to Seasonal Affective Disorder. This susceptibility could be attributed to shared neurobiological mechanisms, particularly disruptions in the pathways of dopamine and serotonin (Biederman J, et al., 1998). When it comes to treatment, those diagnosed with both ADHD and SAD require a diverse range of therapeutic approaches. Light therapy, commonly used for SAD, might also benefit some individuals with ADHD by improving alertness and regulating sleep patterns.   The reduced exposure to natural light during winter months can intensify Seasonal Affective Disorder symptoms. Lastly, disruptions in circadian rhythms have implications for both ADHD and Seasonal Affective Disorder. The shorter days of winter can disrupt the body’s internal clock, which is a factor in SAD. Similarly, ADHD has been associated with disruptions in circadian rhythms, with some individuals displaying symptoms of delayed sleep phase syndrome (Coogan AN, McGowan NM, 2017).

What kind of Treatments are used for Seasonal Affective Disorder?

Effective treatments include light therapy, antidepressants, and cognitive behavioral therapy. Practicing self-compassion and stress reduction can help prepare for difficult seasons and seeking extra support is always a good idea. Ask your doctor about light therapy, it can be helpful.
