Depression

What is depression?

Everyone feels sad or low sometimes, but these feelings usually pass with a little time. Depression (also called major depressive disorder or clinical depression) is different. It can cause severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. It is an illness that can affect anyone—regardless of age, race, income, culture, or education. Research suggests that genetic, biological, environmental, and psychological factors play a role in depression.

Depression may occur with other mental disorders and other illnesses, such as diabetes, cancer, heart disease, and chronic pain. Depression can make these conditions worse, and vice versa. Sometimes medications taken for these illnesses cause side effects that contribute to depression symptoms.

What are the different types of depression?

Two common forms of depression are:

  • Major depression, which includes symptoms of depression most of the time for at least 2 weeks that typically interfere with one’s ability to work, sleep, study, and eat.
  • Persistent depressive disorder (dysthymia), which often includes less severe symptoms of depression that last much longer, typically for at least 2 years.

Other forms of depression include:

  • Perinatal Depression, which occurs when a woman experiences major depression during pregnancy or after delivery (postpartum depression).
  • Seasonal affective disorder, which comes and goes with the seasons, typically starting in late fall and early winter and going away during spring and summer.
  • Depression with symptoms of psychosis, which is a severe form of depression where a person experiences psychosis symptoms, such as delusions (disturbing, false fixed beliefs) or hallucinations (hearing or seeing things that others do not see or hear).

Common symptoms of depression include:

How is depression diagnosed?

To be diagnosed with depression, an individual must have five depression symptoms every day, nearly all day, for at least 2 weeks. One of the symptoms must be a depressed mood or a loss of interest or pleasure in almost all activities. Children and adolescents may be irritable rather than sad.

If you think you may have depression, talk to your health care provider. Primary care providers routinely diagnose and treat depression and refer individuals to mental health professionals, such as psychologists or psychiatrists.

During the visit, your provider may ask when your symptoms began, how long they last, how often they occur, and if they keep you from going out or doing your usual activities. It may help to make some notes about your symptoms before your visit. Certain medications and some medical conditions, such as viruses or a thyroid disorder, can cause the same depression symptoms. Your provider can rule out these possibilities by doing a physical exam, interview, and lab tests.

Depression can affect people differently, depending on their age.

Children with depression may be anxious, cranky, pretend to be sick, refuse to go to school, cling to a parent, or worry that a parent may die.

Older children and teens with depression may get into trouble at school, sulk, be easily frustrated‚ feel restless, or have low self-esteem. They also may have other disorders, such as anxiety and eating disorders, attention-deficit hyperactivity disorder, or substance use disorder. Older children and teens are more likely to experience excessive sleepiness (called hypersomnia) and increased appetite (called hyperphagia). In adolescence, females begin to experience depression more often than males, likely due to the biological, life cycle, and hormonal factors unique to women.

Younger adults with depression are more likely to be irritable, complain of weight gain and hypersomnia, and have a negative view of life and the future. They often have other disorders, such as generalized anxiety disorder, social phobia, panic disorder, and substance use disorders.

Middle-aged adults with depression may have more depressive episodes, decreased libido, middle-of-the-night insomnia, or early morning awakening. They also may more frequently report having gastrointestinal symptoms such as diarrhea or constipation.

Older adults with depression commonly experience sadness or grief or may have other less obvious symptoms. They may report a lack of emotions rather than a depressed mood. Older adults also are more likely to have other medical conditions or pain that may cause or contribute to depression. In severe cases, memory and thinking problems (called pseudodementia) may be prominent.

How is depression treated?

Depression treatment typically involves medication, psychotherapy, or both. If these treatments do not reduce symptoms, brain stimulation therapy may be another treatment option. In milder cases of depression, treatment might begin with psychotherapy alone, and medication added if the individual continues to experience symptoms. For moderate or severe depression, many mental health professionals recommend a combination of medication and therapy at the start of treatment.

Choosing the right treatment plan should be based on a person’s individual needs and medical situation under a provider’s care. It may take some trial and error to find the treatment that works best for you.

Medications

Antidepressants are medications commonly used to treat depression. They take time to work—usually 4 to 8 weeks—and symptoms such as problems with sleep, appetite, or concentration often improve before mood lifts. It is important to give medication a chance before deciding whether or not it works.

Please Note: Some individuals—especially children, teenagers, and young adults—may experience an increase in suicidal thoughts or behavior when taking antidepressants, particularly in the first few weeks after starting or when the dose is changed. All patients taking antidepressants should be watched closely, especially during the first few weeks of treatment.

Treatment-resistant depression occurs when a person doesn’t get better after trying at least two antidepressants. Esketamine is a newer FDA-approved medication for treatment-resistant depression delivered as a nasal spray in a doctor’s office, clinic, or hospital. It often acts rapidly—typically within a couple of hours—to relieve depression symptoms. Individuals usually continue to take an oral antidepressant to maintain the improvement in depression.

Another option for treatment-resistant depression is to add a different type of medication that may make an antidepressant more effective, such as an antipsychotic or anticonvulsant medication or bupropion, an antidepressant that works differently from most.

Medications prescribed by your health care provider for depression can have side effects, but these may lessen over time. Talk to your provider about any side effects that you have. Do not stop taking medications without the help of a health care provider. If you abruptly stop taking your medicine, you may experience severe withdrawal symptoms.

FDA has not approved any natural products for depression. While research is ongoing, some people find natural products, including vitamin D and the herbal dietary supplement St. John’s wort, to help depression. Do not use St. John’s wort or other dietary supplements for depression before talking to your provider.

Psychotherapy

Psychotherapy (also called “talk therapy” or “counseling”) teaches individuals with depression new ways of thinking and behaving and helps with changing habits that contribute to depression. Most psychotherapy occurs with a licensed, trained mental health professional in one-on-one sessions or with other individuals in a group setting. Two effective psychotherapies to treat depression include cognitive behavioral therapy (CBT) and interpersonal therapy (IPT). The use of older forms of psychotherapy, such as dynamic therapy, for a limited time also may help some people with depression.

With CBT, people learn to challenge and change unhelpful thinking patterns and behavior to improve their depressive and anxious feelings. Recent advances in CBT include introducing mindfulness principles and the development of specialized forms of therapy targeting particular symptoms, such as insomnia.

IPT focuses on interpersonal and life events that impact mood and vice versa. The goal of IPT is to help people improve their communication skills within relationships, establish social support networks, and develop realistic expectations to help them deal with crises or other issues that may be contributing to or worsening their depression.

Brain Stimulation Therapy

Brain Stimulation Therapies, which involves activating or inhibiting the brain directly with electricity or magnetic waves, is another option for some people when other depression treatments have not been effective.

The most common forms of brain stimulation therapy include electroconvulsive therapy and repetitive transcranial magnetic stimulation. Other brain stimulation therapies are newer and, in some cases, still experimental.
