Understanding and Treating Seasonal Affective Disorder

Risk Factors for Seasonal Affective Disorder

While the exact cause of SAD is unknown, there are several factors that can increase a person’s risk of developing the condition. These include:

  1. Living in a northern climate, where there is less sunlight during the fall and winter months
  2. Having a family history of depression or SAD
  3. Being female, as women are more likely than men to develop SAD

Diagnosing Seasonal Affective Disorder

If a person is experiencing symptoms of depression during the fall and winter months, it is important to speak with a healthcare provider. A healthcare provider can perform a thorough evaluation to determine if a person has SAD or another form of depression.

During the evaluation, the healthcare provider will ask about the person’s symptoms, medical history, and family history of depression. They may also perform a physical exam and order blood tests to rule out other medical conditions that could be causing the symptoms.

Treating Seasonal Affective Disorder

There are several treatment options available for SAD. The most common treatments include:

  1. Light therapy
  2. Antidepressant medications
  3. Psychotherapy

Light Therapy

Light therapy is a common treatment for SAD. It involves exposure to bright light for a certain amount of time each day. The light used in light therapy is much brighter than regular indoor lighting, and is designed to mimic natural sunlight.

Light therapy works by affecting the body’s internal clock, or circadian rhythm. It helps to regulate the production of hormones such as melatonin and serotonin, which can affect mood and sleep patterns.

Light therapy is typically done in the morning, and involves sitting in front of a light box for 20 to 60 minutes each day. The length of time and the intensity of the light used will depend on the severity of a person’s symptoms.

Antidepressant Medications

Antidepressant medications are another common treatment for SAD. They work by increasing the levels of certain chemicals in the brain that affect mood.

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed type of antidepressant for SAD.
