What Is Depression? Everyone occasionally feels blue or sad, but these feelings are usually fleeting and pass within a couple of days.When a person has a depressive disorder, it interferes with daily life, normal functioning, and causes pain for both the person with the disorder and those who care about him or her. Depression is a common but serious illness, and most who experience it need treatment to get better. Many people with a depressive illness never seek treat­ment. But the vast majority, even those with the most severe depression, can get better with treatment. Intensive research into the il ness has resulted in the development of medications, psychotherapies, and other methods to treat people with this disabling disorder. Depression is a common but serious illness. Most who experience depression need treatment to get better. National Institute of Mental Health

What are the different forms of depression? There are several forms of depressive disorders. The most common are major depressive disorder and dysthymic disorder.
Major depressive disorder, also called major depression,
Bipolar disorder, also
is characterized by a combination of symptoms that inter­ called manic-depressive fere with a person's ability to work, sleep, study, eat, and illness, is not as common enjoy once-pleasurable activities.

However, not all sci­ entists agree on how to characterize and define these forms of depression. They include:
Psychotic depression, which occurs when a severe depres­
sive il ness is accompanied by some form of psychosis, such as a break with reality, hal ucinations, and delusions.
Postpartum depression, which is diagnosed if a new mother
develops a major depressive episode within one month after delivery. It is estimated that 10 to 15 percent of women expe­ rience postpartum depression after giving birth.1
Seasonal affective disorder (SAD), which is character­
ized by the onset of a depressive illness during the winter months, when there is less natural sunlight. The depression general y lifts during spring and summer. SAD may be effec­ tively treated with light therapy, but nearly half of those with SAD do not respond to light therapy alone. Antidepressant medication and psychotherapy can reduce SAD symptoms, either alone or in combination with light therapy.2

What are the symptoms of depression? People with depressive il nesses do not all experience the same symptoms.The severity, frequency and duration of symptoms will vary depending on the individual and his or her particular illness. symptoms
Persistent sad, anxious or "empty" feelings Feelings of hopelessness and/or pessimism Feelings of guilt, worthlessness and/or helplessness Irritability, restlessness Loss of interest in activities or hobbies once pleasurable, including sex Fatigue and decreased energy Difficulty concentrating, remembering details and making decisions Insomnia, early-morning wakefulness, or excessive sleeping Overeating, or appetite loss Thoughts of suicide, suicide attempts Persistent aches or pains, headaches, cramps or digestive problems that do not ease even with treatment National Institute of Mental Health What illnesses often co-exist with depression? Depression often co-exists with other illnesses. Such ill­
nesses may precede the depression, cause it, and/or be a
consequence of it. It is likely that the mechanics behind
the intersection of depression and other il nesses differ
for every person and situation. Regardless, these other co­
occurring illnesses need to be diagnosed and treated.
Anxiety disorders, such as post-traumatic stress disorder
(PTSD), obsessive-compulsive disorder, panic disorder,
social phobia and generalized anxiety disorder, often
accompany depression.3,4 People experiencing PTSD are especial y prone to having co-occurring depression. PTSD is a debilitating condition that can result after a person experi­ ences a terrifying event or ordeal, such as a violent assault, a natural disaster, an accident, terrorism or military combat. People with PTSD often re-live the traumatic event in flash­ backs, memories or nightmares. Other symptoms include irritability, anger outbursts, intense guilt, and avoidance of thinking or talking about the traumatic ordeal. In a National Institute of Mental Health (NIMH)-funded study, researchers found that more than 40 percent of people with PTSD also had depression at one-month and four-month intervals after the traumatic event.5
Alcohol and other substance abuse or dependence may also
co-occur with depression. In fact, research has indicated that the co-existence of mood disorders and substance abuse is pervasive among the U.S. population.6
Depression also often co-exists with other serious medical
illnesses such as heart disease, stroke, cancer, hiv/AiDS,
diabetes, and Parkinson's disease. Studies have shown that
people who have depression in addition to another serious medical illness tend to have more severe symptoms of both depression and the medical il ness, more difficulty adapting to their medical condition, and more medical costs than those who do not have co-existing depression.7 Research has yielded increasing evidence that treating the depression can also help improve the outcome of treating the co-occurring illness.8 What causes depression? There is no single known cause of depression. Rather, it likely results from a combination of genetic, biochemical, environmental, and psychological factors. Research indicates that depressive illnesses are disorders
of the brain. Brain-imaging technologies, such as magnetic
resonance imaging (MRI), have shown that the brains of
people who have depression look different than those of
people without depression.The parts of the brain responsi­
ble for regulating mood, thinking, sleep, appetite and behav­
ior appear to function abnormal y. In addition, important
neurotransmitters—chemicals that brain cells use to com­
municate—appear to be out of balance. But these images
do not reveal why the depression has occurred.
Some types of depression tend to run in families, suggest­ing a genetic link. However, depression can occur in people without family histories of depression as well.9 Genetics research indicates that risk for depression results from the influence of multiple genes acting together with environ­mental or other factors.10 In addition, trauma, loss of a loved one, a difficult relation­ship, or any stressful situation may trigger a depressive episode. Subsequent depressive episodes may occur with or without an obvious trigger. Research indicates that depressive illnesses are disorders of the brain. National Institute of Mental Health How do women experience depression? Depression is more common among women than among men. Biological, life cycle, hormonal and psychosocial factors unique to women may be linked to women's higher depression rate. Researchers have shown that hormones directly affect brain chem­ istry that controls emotions and mood. For example, women are particularly vulnerable to depression after giving birth, when hor­ monal and physical changes, along with the new responsibility of caring for a newborn, can be overwhelming. Many new moth­ ers experience a brief episode of the "baby blues," but some will develop postpartum depression, a much more serious condition that requires active treatment and emotional support for the new mother. Some studies suggest that women who experience post­ partum depression often have had prior depressive episodes. Some women may also be susceptible to a severe form of premen­ strual syndrome (PMS), sometimes cal ed premenstrual dysphoric disorder (PMDD), a condition resulting from the hormonal changes that typically occur around ovulation and before menstruation begins. During the transition into menopause, some women expe­ rience an increased risk for depression. Scientists are exploring how the cyclical rise and fall of estrogen and other hormones may affect the brain chemistry that is associated with depressive illness.11 Final y, many women face the additional stresses of work and home responsibilities, caring for children and aging parents, abuse, pov­ erty, and relationship strains. It remains unclear why some women faced with enormous challenges develop depression, while others with similar challenges do not. How do men experience depression? Men often experience depression differently than women and may have different ways of coping with the symptoms. Men are more likely to acknowledge having fatigue, irritability, loss of interest in once-pleasurable activities, and sleep disturbances, whereas women are more likely to admit to feelings of sadness, worthless­ ness and/or excessive guilt.12,13 Men are more likely than women to turn to alcohol or drugs when they are depressed, or become frustrated, discouraged, irritable, angry and sometimes abusive. Some men throw themselves into their work to avoid talking about their depression with family or friends, or engage in reckless, risky behavior. And even though more women attempt suicide, many more men die by suicide in the United States.14 How do older adults experience depression? Depression is not a normal part of aging, and studies show that most seniors feel satisfied with their lives, despite increased physical ailments. However, when older adults do have depres­ sion, it may be overlooked because seniors may show different, less obvious symptoms, and may be less inclined to experience or acknowledge feelings of sadness or grief.15 In addition, older adults may have more medical conditions such as heart disease, stroke or cancer, which may cause depressive symptoms, or they may be taking medications with side effects that contribute to depression. Some older adults may experience what some doctors call vascular depression, also called arteriosclerotic depression or subcortical ischemic depression. Vascular depression may result when blood ves­ sels become less flexible and harden over time, becoming constricted. Such hardening of vessels prevents normal blood flow to the body's organs, including the brain. Those with vascular depression may have, or be at risk for, a co-existing cardiovascular illness or stroke.16 Although many people assume that the highest rates of sui­ cide are among the young, older white males age 85 and older actually have the highest suicide rate. Many have a depres­ sive il ness that their doctors may not detect, despite the fact that these suicide victims often visit their doctors within one month of their deaths.17 The majority of older adults with depression improve when they receive treatment with an antidepressant, psychotherapy, or a combination of both.18 Research has shown that medica­ tion alone and combination treatment are both effective in reducing the rate of depressive recurrences in older adults.19 Psychotherapy alone also can be effective in prolonging peri­ ods free of depression, especial y for older adults with minor depression, and it is particularly useful for those who are unable or unwilling to take antidepressant medication.20, 21 Depression is not a normal part of aging. National Institute of Mental Health How do children and adolescents experience depression? Scientists and doctors have begun to take seriously the risk of depression in children. Research has shown that childhood depression often persists, recurs and continues into adult­ hood, especially if it goes untreated. The presence of child­ hood depression also tends to be a predictor of more severe illnesses in adulthood.22 A child with depression may pretend to be sick, refuse to go to school, cling to a parent, or worry that a parent may die. Older children may sulk, get into trouble at school, be nega­ tive and irritable, and feel misunderstood. Because these signs may be viewed as normal mood swings typical of children as they move through developmental stages, it may be difficult to accurately diagnose a young person with depression. Before puberty, boys and girls are equally likely to develop depressive disorders. By age 15, however, girls are twice as likely as boys to have experienced a major depressive episode.23 Depression in adolescence comes at a time of great personal change—when boys and girls are forming an identity distinct from their parents, grappling with gender issues and emerg­ ing sexuality, and making decisions for the first time in their lives. Depression in adolescence frequently co-occurs with other disorders such as anxiety, disruptive behavior, eating disorders or substance abuse. It can also lead to increased risk for suicide.22,24 An NIMH-funded clinical trial of 439 adolescents with major depression found that a combination of medication and psy­ chotherapy was the most effective treatment option.25 Other NIMH-funded researchers are developing and testing ways to prevent suicide in children and adolescents, including early diagnosis and treatment, and a better understanding of sui­ Childhood depression often persists, recurs, and continues into adulthood, especially if left untreated. How is depression detected and treated? Depression, even the most severe cases, is a highly treat­able disorder. As with many illnesses, the earlier that treat­ment can begin, the more effective it is and the greater the likelihood that recurrence can be prevented. The first step to getting appropriate treatment is to visit a doctor. Certain medications, and some medical conditions such as viruses or a thyroid disorder, can cause the same symptoms as depression. A doctor can rule out these pos­sibilities by conducting a physical examination, interview and lab tests. If the doctor can eliminate a medical condition as a cause, he or she should conduct a psychological evaluation or refer the patient to a mental health professional. The doctor or mental health professional will conduct a complete diagnostic evaluation. He or she should discuss any family history of depression, and get a complete his­tory of symptoms, e.g., when they started, how long they have lasted, their severity, and whether they have occurred before and if so, how they were treated. He or she should also ask if the patient is using alcohol or drugs, and whether the patient is thinking about death or suicide. Once diagnosed, a person with depression can be treated with a number of methods. The most common treatments are medication and psychotherapy. National Institute of Mental Health Medication
Antidepressants work to normalize naturally occurring
brain chemicals cal ed neurotransmitters, notably serotonin and norepinephrine. Other antidepressants work on the neu­ rotransmitter dopamine. Scientists studying depression have found that these particular chemicals are involved in regu­ lating mood, but they are unsure of the exact ways in which they work.
The newest and most popular types of antidepressant
medications are called selective serotonin reuptake inhibi­
tors (SSRis). SSRIs include fluoxetine (Prozac), citalopram
(Celexa), sertraline (Zoloft) and several others. Serotonin and norepinephrine reuptake inhibitors (SNRIs) are similar to SSRIs and include venlafaxine (Effexor) and duloxetine (Cymbalta). SSRIs and SNRIs are more popular than the older classes of antidepressants, such as tricyclics—named for their chemical structure—and monoamine oxidase inhibitors (MAOIs) because they tend to have fewer side effects. How­ ever, medications affect everyone differently—no one-size­ fits-all approach to medication exists. Therefore, for some people, tricyclics or MAOIs may be the best choice. People taking MAOIs must adhere to significant food and medicinal restrictions to avoid potential y serious interactions. They must avoid certain foods that contain high levels of the chemical tyramine, which is found in many cheeses, wines and pickles, and some medications including decongestants. MAOIs interact with tyramine in such a way that may cause a sharp increase in blood pressure, which could lead to a stroke. A doctor should give a patient taking an MAOI a complete list of prohibited foods, medicines and substances.
For all classes of antidepressants, patients must take regu­
lar doses for at least three to four weeks before they are
likely to experience a full therapeutic effect. They should
continue taking the medication for the time specified by their doctor, even if they are feeling better, in order to prevent a relapse of the depression. Medication should be stopped only under a doctor's supervision. Some medications need to be gradually stopped to give the body time to adjust. Although antidepressants are not habit-forming or addictive, abruptly ending an antidepressant can cause withdrawal symptoms or lead to a relapse. Some individuals, such as those with chronic or recurrent depression, may need to stay on the medication indefinitely. In addition, if one medication does not work, patients should be open to trying another. NIMH-funded research has shown that patients who did not get well after taking a first medica­ tion increased their chances of becoming symptom-free after they switched to a different medication or added another medication to their existing one.26,27 Sometimes stimulants, anti-anxiety medications, or other medications are used in conjunction with an antidepressant, especial y if the patient has a co-existing mental or physical disorder. However, neither anti-anxiety medications nor stim­ ulants are effective against depression when taken alone, and both should be taken only under a doctor's close supervision. What are the side effects of antidepressants? Antidepressants may cause mild and often temporary side effects in some people, but they are usually not long-term. However, any unusual reactions or side effects that inter­
fere with normal functioning should be reported to a
doctor immediately.
National Institute of Mental Health sIde effects
The most common side effects associated with SSRIs and SNRIs include: Headache—usually temporary and will subside. Nausea—temporary and usually short-lived. Insomnia and nervousness (trouble fal ing asleep or waking often during the night)—may occur during the first few weeks but often subside over time or if the dose is reduced. Agitation (feeling jittery). Sexual problems—both men and women can experi­ ence sexual problems including reduced sex drive, erectile dysfunction, delayed ejaculation, or inability to Report any have an orgasm. unusual side Tricyclic antidepressants also can cause side effects effects to including: Dry mouth—it is helpful to drink plenty of water, immediately. chew gum, and clean teeth daily. Constipation—it is helpful to eat more bran cereals, prunes, fruits, and vegetables. Bladder problems—emptying the bladder may be difficult, and the urine stream may not be as strong as usual. Older men with enlarged prostate conditions may be more affected. The doctor should be notified if it is painful to urinate. Sexual problems—sexual functioning may change, and side effects are similar to those from SSRIs. Blurred vision—often passes soon and usual y will not require a new corrective lenses prescription. Drowsiness during the day—usual y passes soon, but driving or operating heavy machinery should be avoided while drowsiness occurs. The more sedating antidepressants are general y taken at bedtime to help sleep and minimize daytime drowsiness.

FDA Warning on Antidepressants Despite the relative safety and popularity of SSRIs and other antidepressants, some studies have suggested that they may have unintentional effects on some people, especially adolescents and young adults. In 2004, the Food and Drug Administration (FDA) conducted a thorough review of published and unpublished controlled clinical trials of antidepressants that involved nearly 4,400 children and adolescents. The review revealed that 4% of those taking antidepressants thought about or attempted suicide (although no suicides occurred), compared to 2% of those receiving placebos. This information prompted the FDA, in 2005, to adopt a "black box" warning label on all antidepressant medications to alert the public about the potential increased risk of suicidal thinking or attempts in children and adolescents taking antidepressants. In 2007, the FDA proposed that makers of all antidepressant medications extend the warning to include young adults up through age 24. A "black box" warning is the most serious type of warning on prescription drug labeling. The warning emphasizes that patients of all ages taking antidepressants should be closely monitored, especially during the initial weeks of treatment. Possible side effects to look for are worsening depression, suicidal thinking or behavior, or any unusual changes in behavior such as sleeplessness, agitation, or withdrawal from normal social situations. The warning adds that families and caregivers should also be told of the need for close monitoring and report any changes to the physician. The latest information from the FDA can be found on their Web site Children, adolescents and young adults taking antidepressants should be closely monitored. National Institute of Mental Health Results of a comprehensive review of pediatric trials conducted between 1988 and 2006 suggested that the benefits of antidepressant medications likely outweigh their risks to children and adolescents with major depression and anxiety disorders.28 The study was funded in part by the National Institute of Mental Health. Also, the FDA issued a warning that combining an SSRI or SNRI antidepressant with one of the commonly-used "triptan" medications for migraine headache could cause a life-threatening "serotonin syndrome," marked by agitation, hal ucinations, elevated body temperature, and rapid changes in blood pressure. Although most dramatic in the case of the MAOIs, newer antidepressants may also be associated with potential y dangerous interactions with other medications. What about St. John's wort? The extract from St. John's wort (Hypericum perforatum), a bushy, wild-growing plant with yellow flowers, has been used for centuries in many folk and herbal remedies. Today in Europe, it is used extensively to treat mild to moderate depression. In the United States, it is one of the top-selling botanical products. To address increasing American interests in St. John's wort, the National Institutes of Health conducted a clinical trial to determine the effectiveness of the herb in treating adults who have major depression. Involving 340 patients diagnosed with major depression, the eight-week trial randomly assigned one-third of them to a uniform dose of St. John's wort, one- third to a commonly prescribed SSRI, and one-third to a placebo. The trial found that St. John's wort was no more effective than the placebo in treating major depression.29 Another study is looking at the effectiveness of St. John's wort for treating mild or minor depression. Other research has shown that St. John's wort can interact unfavorably with other medications, including those used to control HIV infection. On February 10, 2000, the FDA issued a Public Health Advisory letter stating that the herb appears to interfere with certain medications used to treat heart disease, depression, seizures, certain cancers, and organ transplant rejection. The herb also may interfere with the effectiveness of oral contraceptives. Because of these potential interactions, patients should always consult with their doctors before taking any herbal supplement. Psychotherapy Several types of psychotherapy—or "talk therapy"—can help people with depression. Some regimens are short-term (10 to 20 weeks) and other regimens are longer-term, depending on the needs of the indi­ vidual. Two main types of psychotherapies—cognitive-behav­ ioral therapy (CBT) and interpersonal therapy (IPT)—have been shown to be effective in treating depression. By teaching new ways of thinking and behaving, CBT helps people change negative styles of thinking and behaving that may contribute to their depression. IPT helps people understand and work through troubled personal relationships that may cause their depression or make it worse. For mild to moderate depression, psychotherapy may be the best treatment option. However, for major depression or for certain people, psychotherapy may not be enough. Studies have indicated that for adolescents, a combination of medica­ tion and psychotherapy may be the most effective approach to treating major depression and reducing the likelihood for recurrence.25 Similarly, a study examining depression treat­ ment among older adults found that patients who responded to initial treatment of medication and IPT were less likely to have recurring depression if they continued their combina­ tion treatment for at least two years.21 Electroconvulsive Therapy For cases in which medication and/or psychotherapy does not help alleviate a person's treatment-resistant depression, electroconvulsive therapy (ECT) may be useful. ECT, for­ merly known as "shock therapy," once had a bad reputation. But in recent years, it has greatly improved and can provide relief for people with severe depression who have not been able to feel better with other treatments. National Institute of Mental Health

Before ECT is administered, a patient takes a muscle relax­ ant and is put under brief anesthesia. He or she does not consciously feel the electrical impulse administered in ECT. A patient typical y will undergo ECT several times a week, and often wil need to take an antidepressant or mood sta­ bilizing medication to supplement the ECT treatments and prevent relapse. Although some patients will need only a few courses of ECT, others may need maintenance ECT, usually once a week at first, then gradually decreasing to monthly treatments for up to one year. ECT may cause some short-term side effects, including confusion, disorientation and memory loss. But these side effects typically clear soon after treatment. Research has indicated that after one year of ECT treatments, patients showed no adverse cognitive effects.30 What efforts are underway to improve treatment? Researchers are looking for ways to better understand, diagnose and treat depression among all groups of people. New potential treatments are being tested that give hope to those who live with depression that is particularly difficult to treat, and researchers are studying the risk factors for depression and how it affects the brain. NIMH continues to fund cutting-edge research into this debilitating disorder. For more information on NIMH-funded research on depression, visit

If you know someone who is depressed, it affects you too. The first and most important thing you can do to help a friend or relative who has depression is to help him or her get an appropriate diagnosis and treatment. You may need to make an appointment on behalf of your friend or relative and go with him or her to see the doctor. Encourage him or her to stay in treatment, or to seek different treatment if no improvement occurs after six to eight weeks. help a frIend or relatIve
Offer emotional support, understanding, patience and encouragement. Engage your friend or relative in conversation, and listen carefully. Never disparage feelings your friend or relative expresses, but point out realities and offer hope. Never ignore comments about suicide, and report them to your friend's or relative's therapist or doctor. Invite your friend or relative out for walks, outings and other activities. Keep trying if he or she declines, but don't push him or her to take on too much too soon. Although diversions and company are needed, too many demands may increase feelings of failure. Remind your friend or relative that with time and treatment, the depression will lift. National Institute of Mental Health How can I help myself if I am depressed? If you have depression, you may feel exhausted, helpless and hopeless. It may be extremely difficult to take any action to help yourself. But it is important to realize that these feelings are part of the depression and do not accurately reflect actual circumstances. As you begin to recognize your depression and begin treatment, negative thinking will fade. help yourself
Engage in mild activity or exercise. Go to a movie, a ballgame, or another event or activity that you once enjoyed. Participate in religious, social or other activities. Set realistic goals for yourself. Break up large tasks into small ones, set some priorities and do what you can as you can. Try to spend time with other people and confide in a trusted friend or relative.Try not to isolate yourself, and let others help you. Expect your mood to improve gradually, not immediately. Do not expect to suddenly "snap out of " your depression. Often during treatment for depression, sleep and appetite will begin to improve before your depressed mood lifts. Postpone important decisions, such as getting married or divorced or changing jobs, until you feel better. Discuss decisions with others who know you well and have a more objective view of your situation. Remember that positive thinking will replace negative thoughts as your depression responds to treatment. Where can I go for help? If you are unsure where to go for help, ask your family doctor. Others who can help are listed below. mental health resources
Mental health specialists, such as psychiatrists, psycholo­ gists, social workers, or mental health counselors Health maintenance organizations Community mental health centers Hospital psychiatry departments and outpatient clinics Mental health programs at universities or medical schools State hospital outpatient clinics Family services, social agencies or clergy Peer support groups Private clinics and facilities Employee assistance programs Local medical and/or psychiatric societies You can also check the phone book under "mental health," "health," "social services," "hotlines," or "physicians" for phone numbers and addresses. An emergency room doctor also can provide temporary help and can tell you where and how to get further help. National Institute of Mental Health
