Depressive disorder, frequently referred to simply as depression, is more than just feeling sad or going through a rough patch. It’s a serious mental health condition that requires understanding and medical care. Left untreated, depression can be devastating for those who have it and their families. Fortunately, with early detection, diagnosis and a treatment plan consisting of medication, psychotherapy and healthy lifestyle choices, many people can and do get better.
Some will only experience one depressive episode in a lifetime, but for most, depressive disorder recurs. Without treatment, episodes may last a few months to several years.
An estimated 16 million American adults—almost 7% of the population—had at least one major depressive episode in the past year. People of all ages and all racial, ethnic and socioeconomic backgrounds experience depression, but it does affect some groups more than others.

Depression can present different symptoms, depending on the person. But for most people, depressive disorder changes how they function day-to-day, and typically for more than two weeks. Common symptoms include:
Depression does not have a single cause. It can be triggered by a life crisis, physical illness or something else—but it can also occur spontaneously. Scientists believe several factors can contribute to depression:
To be diagnosed with depressive disorder, a person must have experienced a depressive episode lasting longer than two weeks. The symptoms of a depressive episode include:
Many treatment options are available for depression, but how well treatment works depends on the type of depression and its severity.
Psychotherapy (or talk therapy) has an excellent track record of helping people with depressive disorder. While some psychotherapies have been researched more than others, many types can be helpful and effective. A good relationship with a therapist can help improve outcomes.
For most people, psychotherapy and medications give better results together than either alone, but this is something to review with your mental health care provider. Further, many clinicians are trained in more than one kind of psychotherapy, so ask your clinician what kind of psychotherapy they practice and how it can help you. A few examples include:
Psychoeducation involves teaching individuals about their illness, how to treat it and how to recognize signs of relapse. Family psychoeducation is also helpful for family members who want to understand what their loved one is experiencing.
Support groups, meanwhile, provide participants an opportunity to share experiences and coping strategies. Support groups may be for the person with the mental health condition, for family/friends or a combination of both. Mental health professionals lead some support groups, but groups can also be peer-led.

For some people, antidepressants may help reduce or control symptoms. Antidepressants often take 2-4 weeks to begin having an effect and up to 12 weeks to reach full effect. Most people will have to try various doses or medications to find what works for them. Here are some antidepressants commonly used to treat depression:
Selective serotonin reuptake inhibitors (SSRIs) act on serotonin, a brain chemical. They are the most common medications prescribed for depression.
Serotonin and norepinephrine reuptake inhibitors (SNRIs) are the second most common antidepressants. These medications increase serotonin and norepinephrine.
Norepinephrine-dopamine reuptake inhibitors (NDRIs) increase dopamine and norepinephrine. Bupropion (Wellbutrin) is a popular NDRI medication, which causes fewer (and different) side effects than other antidepressants. For some people, bupropion causes anxiety symptoms, but for others it is an effective treatment for anxiety.
Mirtazapine (Remeron) targets specific serotonin and norepinephrine receptors in the brain, thus indirectly increasing the activity of several brain circuits. Mirtazapine is used less often than newer antidepressants (SSRIs, SNRIs and bupropion) because it is associated with more weight gain, sedation and sleepiness. However, it appears to be less likely to result in insomnia, sexual side effects and nausea than the SSRIs and SNRIs.
Second-generation antipsychotics (SGAs), or “atypical antipsychotics,” treat schizophrenia, acute mania, bipolar disorder and bipolar mania and other mental illnesses. SGAs can be used for treatment-resistant depression.
Tricyclic antidepressants (TCAs) are older medications, seldom used today as initial treatment for depression. They work similarly to SNRIs but have more side effects. They are sometimes used when other antidepressants have not worked. TCAs may also ease chronic pain.
• Amitriptyline (Elavil)
• Desipramine (Norpramin)
• Doxepin (Sinequan)
• Imipramine (Tofranil)
• Nortriptyline (Pamelor, Avantyl)
• Protriptyline (Vivactil)
Monoamine oxidase inhibitors (MAOIs) are less used today because newer, more effective medications with fewer side effects have been found. These medications can never be used in combination with SSRIs. MAOIs can sometimes be effective for people who do not respond to other medications.
For some, brain stimulation therapies may be effective, typically after other treatments have not been effective.
Relying solely on CAM methods is not enough to treat depression, but they may be useful when combined with psychotherapy and medication. Discuss your ideas of CAM interventions with your health care professional to be sure they will not cause side effects or adverse reactions.
