Dr. Morrow’s Show Notes

What is seasonal affective disorder?

• Seasonal affective disorder (SAD) is a type of depression that is triggered by the seasons of the year.
  • Symptoms usually begin in late fall or early winter.
  • People with SAD usually feel better in the spring and summer.
  • It is thought that SAD is related to changes in the amount of daylight during different times of the year.
  • Some people have SAD with depressive episodes in the summer instead of winter. This is much less common.

How common is Seasonal Affective Disorder?

• Between 4% and 6% of people in the United States suffer from SAD.
  • Another 10% to 20% may experience it in a milder form.
  • SAD is more common in women than in men.
  • Some children and teenagers get SAD.
  • But it usually doesn’t start in people younger than 20 years of age.
  • The risk of SAD decreases for adults as they age.
  • SAD is more common in northern regions of the United States.
  • Winters are typically longer and harsher there.
  • There is also less sunlight because they are farther away from the equator.

Symptoms of Seasonal Affective Disorder

• Not everyone who has SAD experiences the same symptoms.
  • Common symptoms of winter-onset SAD include:
• change in appetite, especially craving sweet or starchy foods
• weight gain
• fatigue
• sleeping more than normal
• difficulty concentrating
• irritability and anxiety
• increased sensitivity to rejection
• avoidance of social situations
• loss of interest in the activities you used to enjoy
• feelings of guilt or hopelessness
• physical problems, such as headaches.

Symptoms of summer-onset SAD include:

• loss of appetite
• weight loss
• insomnia
• irritability and anxiety
• agitation

Symptoms of SAD tend to come back year after year.

• • They usually come and go at about the same time every year.
  • If you think this could be happening to you, call your family doctor.

What causes Seasonal Affective Disorder?

• In most cases, SAD seems to be related to the loss of sunlight in the fall and winter.
  • Researchers have found that reduced sunlight can affect the body in ways that could contribute to SAD.
  • These include:
    • Circadian rhythm (biological clock) – The decrease in sunlight could disrupt your body’s natural rhythms.
      • This could lead to feelings of depression.
    • Serotonin levels – Serotonin is a brain chemical that affects your mood.
      • Reduced sunlight could cause serotonin levels to drop.
      • This could trigger depression.
    • Melatonin levels – Melatonin is a brain chemical that regulates sleep.
      • More darkness causes the body to produce more melatonin.
      • More melatonin could make you feel more tired and lethargic.
      • These are common symptoms of depression

• Vitamin D levels – It is believed that vitamin D plays a role in serotonin levels.
  • Much of the vitamin D we get is from the sun.
  • Less sunlight could lead to a deficiency in vitamin D.
  • This can cause depression symptoms.

• Some people have a higher risk of developing SAD.
  • Factors that increase risk include:
    • Being female.
      • Four times as many women are diagnosed with SAD than men.
    • Living far from the equator.
      • In the United States, living farther north increases your risk.
      • These areas get less sunlight in fall and winter.
    • Family history.
      • Having family members with SAD or other forms of depression increases your risk.
    • Having depression or bipolar disorder.
      • If you have one of these conditions, your symptoms may worsen with the seasons.
    • Young age.
      • SAD is more common among younger adults.
      • It has been reported in teens and children.
      • Your chances of getting it decrease as you get older.

How is SAD diagnosed?

• Your doctor will ask you about your symptoms, thoughts, feelings, and behavior.
• He or she may perform a physical exam.
• They may request lab tests to rule out other conditions that cause symptoms similar to SAD.
• They may refer you to a specialist to diagnose your condition.
  • This could be a psychologist or a psychiatrist.

Can SAD be prevented or avoided?

• There’s not much you can do to avoid getting SAD.
• But you can take steps to manage it so your symptoms don’t get worse.
• Some people start treatment before their symptoms start.
• They also continue treatment past the time that their symptoms normally go away.
• Others need continuous treatment to control their symptoms

SAD treatment

• The three main ways SAD is treated are with:
  • light therapy,
  • behavioral therapy, or
  • Your doctor may want to combine therapies if using one does not work for you.

Light therapy

• Light therapy is designed to make up for the lack of sunlight during the fall and winter.
  • It has been used to treat SAD since the 1980s.
  • You sit in front of a special light box every day.
  • The box emits a bright white light that mimics natural sunlight.
    • It seems to make a change in brain chemicals that regulate your mood.
    • The amount of time you sit in front of the light box depends on the strength of the light.
    • It is usually between 20 and 60 minutes.

• There are other types of light therapy.
  • Instead of sitting in front of a box, you can wear a visor that emits light.
  • Another kind is a “dawn simulator.”
    • This light turns on early in the morning in your bedroom.
    • It mimics a natural sunrise and gradually increases in brightness.
    • This allows you to wake up naturally, without using an alarm.

• If light therapy helps, you’ll continue it until enough sunlight returns.
  • This usually happens in spring.
  • Stopping light therapy too soon can result in a return of symptoms.

• When used properly, light therapy seems to have very few side effects.
  • Some side effects include eyestrain, headache, fatigue, and irritability.
  • If you use it too late in the day, you could have trouble sleeping.
  • Talk to your doctor before starting light therapy if you have:
    • bipolar disorder
    • skin that is sensitive to sunlight.
    • conditions that make your eyes vulnerable to sunlight damage.

• Tanning beds should not be used to treat SAD.
  • The light sources in tanning beds are high in ultraviolet (UV) rays.
  • These harm your eyes and your skin.
  • They also cause skin cancer.

Behavioral therapy

• Talk therapy or behavioral therapy can help you identify negative thoughts.
  • Then you replace those with more positive thoughts.
  • Therapy can help you learn healthy ways to manage your symptoms of SAD.
  • You can also learn how to manage stress.

Medicines

• Your doctor might recommend you take medicine to help with your symptoms, especially if they are severe.
  • Selective Serotonin Reuptake Inhibitors (SSRIs) are often used to treat depression.

• You may have to take the medicine for several weeks before you feel better.
  • You may have to try more than one medicine to find the one that works best for you.
• You can also make lifestyle changes that can help your symptoms.
• Let as much natural light as possible into your home or office.
  • Open blinds, sit close to windows, and keep your environments as bright as possible.

• Get outside when you can.
  • Even if it’s cold or cloudy, the light can still benefit you.

• Keep physically active.
  • Exercise and activity boost endorphins and relieve stress.
  • Both of these can keep you feeling better.

Living with Seasonal Affective Disorder

• The keys to living with SAD are to plan ahead and to manage your symptoms.
• Follow your treatment plan.
  • This includes going to appointments, taking medicines, and following up if things aren’t working.
• Take care of your body.
  • Eat healthy foods and get enough sleep.
• Exercise has been shown to have the same effect on depression as antidepressants.
• Have a plan.
  • Know what you will do when your depression symptoms start to get worse.
  • Watch for early signs and take action before you feel bad.

• Don’t turn to alcohol or drugs.
  • They make depression worse.
  • They can also have negative reactions with antidepressants.

• Manage stress.
  • You can’t avoid stress, so you have to learn to manage it.
  • Talk to a counselor or read about ways to handle stress better.

• Don’t isolate yourself.
  • It’s harder to be social when you’re depressed.
    • But being alone can make you feel worse.
    • Try to reach out as much as you can.

• Start treatment early.
  • If you know your symptoms usually start in October, start your treatments in September, before symptoms start.
  • You might be able to prevent them.

• Plan ahead.
  • Some people purposely plan their lives to be very busy during the time they normally feel down.
  • This helps prevent them from “hiding out” at home, because they have already made commitments.

• Take a trip.
  • Plan a trip to a warmer, sunnier climate during the winter.
  • The positive feelings will extend before, during, and after your trip.

• What treatment is best for me?
• Should I use light therapy?
• What changes can I make at home to help myself?
• What is causing my SAD?
• How long will I have to continue treatment?
• Should I talk with a counselor?
