Season Affective Disorder Symptoms

By Mayo Clinic Staff

In most cases, seasonal affective disorder symptoms appear during late fall or early winter and go away during the sunnier days of spring and summer. However, some people with the opposite pattern have symptoms that begin in spring or summer. In either case, symptoms may start out mild and become more severe as the season progresses.

Fall and winter seasonal affective disorder (winter depression)

Winter-onset seasonal affective disorder symptoms include:
•Loss of energy
•Heavy, “leaden” feeling in the arms or legs
•Social withdrawal
•Loss of interest in activities you once enjoyed
•Appetite changes, especially a craving for foods high in carbohydrates
•Weight gain
•Difficulty concentrating

Spring and summer seasonal affective disorder (summer depression)

Summer-onset seasonal affective disorder symptoms include:
•Trouble sleeping (insomnia)
•Weight loss
•Poor appetite
•Increased sex drive

Seasonal changes in bipolar disorder

In some people with bipolar disorder, spring and summer can bring on symptoms of mania or a less intense form of mania (hypomania). This is known as reverse seasonal affective disorder. Signs and symptoms of reverse seasonal affective disorder include:
•Persistently elevated mood
•Unbridled enthusiasm out of proportion to the situation
•Rapid thoughts and speech

When to see a doctor

It’s normal to have some days when you feel down. But if you feel down for days at a time and you can’t seem to get motivated to do activities you normally enjoy, see your doctor. This is particularly important if you notice that your sleep patterns and appetite have changed or if you feel hopeless, think about suicide, or find yourself turning to alcohol for comfort or relaxation.
