Definition

Depression may be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us feel this way at one time or another for short periods.

True clinical depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for an extended period of time.

Causes & Risks

Depression often runs in families. This may due to your genes (inherited), learned behavior, or both. Even if your genes make you more likely to develop depression, a stressful or unhappy life event usually triggers the onset of a depressive episode.

Depression may be brought on by:

• Alcohol or drug abuse
• Childhood events like abuse or neglect
• Chronic stress
• Death of a friend or relative
• Disappointment at home, work, or school (in teens, this may be breaking up with a boyfriend or girlfriend, failing a class, or parents divorcing)
• Drugs such as sedatives and high blood pressure medications
• Medical conditions such as hypothyroidism (underactive thyroid), cancer, or hepatitis
• Nutritional deficiencies (such as a lack of folate and omega-3 fatty acids)
• Overly negative thoughts about one’s self and life, self blame, and ineffective social problem solving skills
• Prolonged pain or having a major illness
• Sleeping problems
• Social isolation (common in the elderly)

Tests & Diagnostics

The guidelines for diagnosis of major depressive disorder and dysthymic disorder are found in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM IV). In addition to an interview, several clinical inventories or scales may be used to assess a patient’s mental status and determine the presence of depressive symptoms. Among these tests are: the Hamilton Depression Scale (HAM-D), Child Depression Inventory (CDI), Geriatric Depression Scale (GDS), Beck Depression Inventory (BDI), and the Zung Self-Rating Scale for Depression. These tests may be administered in an outpatient or hospital setting by a general practitioner, social worker, psychiatrist, or psychologist.

Treatments

If you are depressed for 2 weeks or longer, you should contact your doctor, who can offer treatment options. Regardless of whether you have mild or major depression, the following self-care steps can help:

• Get enough sleep.
• Follow a healthy, nutritious diet.
• Exercise regularly.
• Avoid alcohol, marijuana, and other recreational drugs.
• Get involved in activities that make you happy, even if you don’t feel like it.
• Spend time with family and friends.
• Try talking to clergy or spiritual advisors who may help give meaning to painful experiences.
• Consider prayer, meditation, tai chi, or biofeedback as ways to relax or draw on your inner strengths.
• Add omega-3 fatty acids to your diet, which you can get from cold-water fish like tuna, salmon, or mackerel.
• Take folate (vitamin B9) in the form of a multivitamin (400 to 800 micrograms).

If your depression occurs in the fall or winter months, try light therapy using a special lamp that mimics the sun.

Many people try a popular over-the-counter herb called St. John’s wort. Some studies do suggest that this herbal remedy may be helpful for mild depression, but not moderate or severe. Be aware that St. John’s wort has potential drug interactions and should NOT be taken with prescription antidepressants, birth control pills, protease inhibitors for HIV, theophylline, warfarin, digoxin, reserpine, cyclosporine, or loperamide. Talk to your doctor if you are thinking about trying this herb for mild depression.

If you have moderate to severe depression, the most effective treatment plan will likely be a combination of counseling and medication.

Drugs

Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac) and sertraline (Zoloft), reduce depression by increasing levels of serotonin, a neurotransmitter. Some clinicians prefer SSRIs for treatment of dysthymic disorder. Anxiety, diarrhea, drowsiness, headache, sweating, nausea, poor sexual functioning, and insomnia all are possible side effects of SSRIs. A recent study shows this generation of drugs increases patients’ risk of gastrointestinal bleeding.

Tricyclic antidepressants (TCAs) are less expensive than SSRIs, but have more severe side effects including persistent dry mouth, sedation, dizziness, and cardiac arrhythmias. Because of these side effects, caution is taken when prescribing TCAs to elderly patients. TCAs include amitriptyline (Elavil), imipramine (Tofranil), and nortriptyline (Aventyl, Pamelor). A 10-day supply of TCAs can be lethal if ingested all at once, so these drugs may not be a preferred treatment option for patients at risk for suicide.

Monoamine oxidase inhibitors (MAO inhibitors), such as tranylcypromine (Parnate) and phenelzine (Nardil), block the action of monoamine oxidase (MAO), an enzyme in the central nervous system. Patients taking MAOIs must avoid foods high in tyramine (found in aged cheeses and meats) to avoid potentially serious hypertensive side effects.

Heterocyclics include bupropion (Wellbutrin) and trazodone (Desyrel). Bupropion is prescribed to patients with a seizure disorder. Side effects include agitation, anxiety, confusion, tremor, dry mouth, fast or irregular heartbeat, headache, low blood pressure, and insomnia. Because trazodone has a sedative effect, it is useful in treating depressed patients with insomnia. Other possible side effects of trazodone include dry mouth, gastrointestinal distress, dizziness, and headache. In 2003, Well-butrin’s manufacturer released a once-daily version of the drug that offered low risk of sexual side effects or weight gain.

• Arum metallicum for severe depression
• Ignatia for adjustment disorder

Complications

Dysthymia commonly occurs in tandem with other psychiatric and physical conditions. Up to 70% of dysthymic patients have both dysthymic disorder and major depressive disorder, known as double depression. Substance abuse, panic disorders, personality disorders, social phobias, and other psychiatric conditions also are found in many dysthymic patients. Dysthymia is prevalent in patients with certain medical conditions, including multiple sclerosis, AIDS, hypothyroidism, chronic fatigue syndrome, Parkinson’s disease, diabetes, and postcardiac transplantation. The connection between dysthymic disorder and these medical conditions is unclear, but it may be related to the way the medical condition and/or its pharmacological treatment affects neurotransmitters. Dysthymic disorder can lengthen or complicate the recovery of patients also suffering from medical conditions.

Along with an underlying feeling of depression, people with dysthymic disorder experience two or more of the following symptoms on an almost daily basis for a period for two or more years (most suffer for five years), or one year or more for children:

• under or overeating
• insomnia or hypersomnia
• low energy or fatigue
• low self-esteem
• poor concentration or trouble making decisions
• altered libido
• altered appetite
• altered motivation
• feelings of hopelessness

Prevention

Healthy lifestyle habits can help prevent depression, or lessen the chances of it happening again. These habits include eating properly, sleeping adequately, exercising regularly, learning to relax, and not drinking alcohol or using drugs.

Counseling may help you through times of grief, stress, or low mood. Family therapy may be particularly important for teens who feel blue.

If you feel socially isolated or lonely, try volunteering or getting involved in group activities.
