We all feel sad or discouraged at times. When these feelings last for more than two weeks and interfere with a person’s interest in or enjoyment of life, he or she may be suffering from a mood disorder. Depression is a serious medical illness that can be successfully treated, usually with a combination of psychotherapy and medicine.
Common symptoms of depression include:
- Feeling sad, blue, or tearful
- Restlessness or irritability
- Loss of energy or increased fatigue
- Pessimistic, negative, and repetitive thinking
- Loss of interest or pleasure in previously enjoyable activities
- Feelings of guilt or worthlessness
- Difficulty thinking, concentrating, or making decisions
- Changes in appetite
- Insomnia or oversleeping
- Feelings of hopelessness
- Thoughts of death or suicide
Depression can affect anyone—even a person who appears to live in relatively ideal circumstances. But several factors can play a role in the onset of depression:
Abnormalities in two chemicals in the brain, serotonin and norepinephrine, might contribute to symptoms of depression, including anxiety, irritability and fatigue. Other brain networks undoubtedly are involved as well; scientists are actively seeking new knowledge in this area.
Depression can run in families.
People with low self-esteem, who are easily overwhelmed by stress, or who are generally pessimistic appear to be vulnerable to depression.
Continuous exposure to violence, neglect, abuse or poverty may make people who are already susceptible to depression all the more vulnerable to the illness. Also, a medical condition (e.g., a brain tumor or vitamin deficiency) can cause depression, so it is important to be evaluated by a health care provider.
Depression is among the most treatable of mental disorders; the majority of people with depression eventually respond well to treatment, and almost all patients gain some relief from their symptoms.
Antidepressants may be prescribed to correct imbalances in the levels of chemicals in the brain. These medications are not sedatives, “uppers” or tranquilizers, and they are not habit-forming.
Antidepressants may produce some improvement within the first week or two of treatment. Full benefits may not be realized for two to three months. If a patient feels little or no improvement after several weeks, his or her psychiatrist will alter the dose of the medication or will add or substitute another antidepressant.
Psychotherapy, or “talk therapy,” is sometimes used alone for treatment of mild depression; for moderate to severe depression, it is often used in combination with antidepressant medications. Psychotherapy may involve only the individual patient, but it can include others. For example, family or couples therapy can help address specific issues arising within these close relationships.

Types of depression
There are several types of depressive disorders. The—major depression, dysthymia, and bipolar disorder—can occur with any of the anxiety disorders.
Major depression involves multiple symptoms of depression which last for at least a two-week period. An episode of major depression is disabling and will interfere with the ability to work, study, eat, and sleep. Major depressive episodes may occur once or twice in a lifetime, or they may re-occur frequently. They may also take place spontaneously, during or after the death of a loved one, a romantic breakup, a medical illness, or other life event.
Dysthymia is a less severe, long-term, and chronic form of depression. It involves the same symptoms as major depression, mainly low energy, poor appetite or overeating, and insomnia or oversleeping. It can manifest as stress, irritability, and mild anhedonia, which is the inability to derive pleasure from most activities.
People with dysthymia might be thought of as always seeing the glass as half empty.
Bipolar disorder, once called manic-depression, is characterized by a mood cycle that shifts from severe highs (mania) or mild highs (hypomania) to severe lows (depression).
During the manic phase, a person may experience abnormal or excessive elation, irritability, a decreased need for sleep, grandiose notions, increased talking, racing thoughts, increased sexual desire, markedly increased energy, poor judgment, and inappropriate social behavior.
During the depressive phase, a person experiences the same symptoms as would a sufferer of major depression. Mood swings from manic to depressive are often gradual, although occasionally they can occur abruptly. Learn more about bipolar disorder.
Seasonal Affective Disorder
Some people experience a serious mood change during the winter months, when there is less natural sunlight. This condition is called seasonal affective disorder, or SAD. Treatment of SAD often includes light therapy.
Up to 70 percent of all new mothers experience the “baby blues,” a short-lasting condition after childbirth that doesn’t impair functioning and doesn’t require medical attention. For 13% of new mothers, the condition is more debilitating and long-lasting. Symptoms can include a lack of interest in or fear of harming the baby. These symptoms may cause new mothers to feel isolated, guilty, or ashamed. Getting treatment is important for both the mother and the child.
