Fact Checked

Depression is a serious medical illness that affects around 7% of adults, which is over 20 million people in the United States, according to the National Institute of Mental Health. Children can also have depression, with around 4% of children in the U.S. having a diagnosis of depression, according to the Centers for Disease Control and Prevention (CDC).

What is depression?

Major depressive disorder, often referred to as depression, can range from mild to severe, and symptoms include:
  • Feeling sad 
  • Loss of interest in activities you once enjoyed
  • Weight loss or gain
  • Trouble sleeping or sleeping too much
  • Fatigue and feeling tired 
  • Feeling worthless or hopeless
  • Problems with concentration
  • Suicidal thoughts or preoccupation with death
The causes of depression are complex and may involve a mix of genetic, biological, environmental, and psychological factors. Changes in the brain, including how certain brain chemicals (like serotonin) work, might play a part in depression. Also, if your family has a history of depression, you're more likely to experience it, as genetics may be a risk factor. Stressful life events such as trauma or loss may also trigger depression.

Clinical depression can affect people from all walks of life. Women, in particular, may be more vulnerable to experiencing depression than men, although depression can affect both men and women. Despite being a common condition, depression is often underdiagnosed and undertreated.

How is depression diagnosed?

There isn’t a laboratory test or scan to diagnose depression. Doctors base their diagnosis on a description of your symptoms and look for specific information on your mood, behavior, and daily activities. During an initial health care assessment, you might be asked to complete screening questionnaires, such as:
  • Beck Depression Inventory: Twenty-one questions about your symptoms. You respond to each item with a score of zero through three. 
  • Hamilton Depression Rating Scale: A questionnaire with 21 questions and is frequently used to determine the severity of your depression after diagnosis. 
  • Zung Self-Rating Scale: A rating scale that measures the severity of your depressive symptoms. The scale consists of 20 questions and is then given a score between 20 and 80. A score above 69 indicates severe depression. 
Your answers on these screening questionnaires help your doctor understand the severity and type of depression you have. A diagnosis requires symptoms to be present most of the day, occur more often than not, and persist for a period over two weeks. 

Many people start the diagnostic process with their primary physician. Your physician might request laboratory tests to rule out physical causes of your symptoms; for example, thyroid disorders and vitamin deficiencies may cause depressive symptoms. 

During your doctor’s appointment, make sure your physician is aware of all medications you are taking, as some drugs can cause side effects that may mimic symptoms of depression. If you are diagnosed with depression, you may be prescribed antidepressants or referred to a mental health specialist for further care. 

Once you receive a diagnosis of depression, here are some questions you can ask your doctor:

  • What type of depression do I have?
  • Do you suggest medications, psychotherapy, or both?
  • Can depression affect my sleep and eating habits?
  • Can my depression be causing physical pain?
  • Are there other health conditions that could be causing these symptoms?
  • What medication do you suggest, and what are the side effects of it?
  • Are there lifestyle changes I can make to improve my symptoms?
  • Are there alternative treatments?
You should also talk to your doctor about a plan for an emergency. Many people with depression are suicidal or have thoughts of harming themselves. You should know what steps you, and your loved ones, should take if you feel you might hurt yourself, such as calling the National Suicide Prevention Lifeline by dialing 988.

Depression treatment options

There is no definitive cure for depression; however, there are many effective treatments to reduce or eliminate symptoms. The type of depression, how long symptoms have been present, other health conditions, and tolerance of side effects all play a role in determining which treatment is best for you. 

Almost all people with depression receive some relief with treatment, with between 80% and 90% responding well to treatment. Treatment may include prescription drugs, such as selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs); psychotherapy, such as cognitive-behavioral therapy or interpersonal therapy; or both medication and psychotherapy. 

For people with treatment-resistant depression, or depression that does not respond to other treatments, various options are available. For example, electroconvulsive therapy (ECT) is sometimes used for those who have not responded to other treatments. A five-year study found that using a vagus nerve stimulation device can also help improve the quality of life in those with treatment-resistant depression. You can find ongoing clinical trials on the website CenterWatch.com

The following provides an overview of each type of treatment:

Psychotherapy

Psychotherapy, also known as talk therapy, is effective in treating depressive disorder. Some of the more common types of psychotherapy include:
  • Cognitive-behavioral therapy: Works to help an individual change unhelpful thought patterns and provide practical steps for managing symptoms.
  • Interpersonal therapy: Looks at external factors, such as relationships, and their role as contributing factors to depressive symptoms. The therapist works with you to improve personal relationships and find ways to resolve conflicts. 
  • Psychodynamic therapy: Places emphasis on resolving past issues that might be contributing to negative behaviors and feelings. 
Other methods that may involve some aspect of psychotherapy include:
  • Psychoeducation: Teaches you about depression symptoms, how to recognize early warning signs and steps to take before a relapse occurs.
  • Support groups: Can be led by a therapist or by someone who also has depression. During group therapy sessions, you can talk freely about your feelings and share experiences as well as practical ways to overcome negative emotions.

Brain stimulation therapies

Your doctor might suggest brain stimulation therapies if other treatment methods have not provided relief from symptoms. These include electroconvulsive therapy, repetitive transcranial magnetic stimulation, and vagus nerve stimulation. They work by stimulating different areas of the brain. 

Antidepressant medications

There are several different classes of antidepressant medications, and each works to relieve symptoms differently. Antidepressants may take around two weeks to start improving symptoms and can take up to eight weeks or more to be fully effective. It may require trying a few different dosages and medications before finding the one that works for you. 

Medications for depression target specific brain chemicals, called neurotransmitters, such as serotonin, norepinephrine, and dopamine. The most commonly used classes of drugs used are:

Selective serotonin reuptake inhibitors

SSRIs target serotonin and are the most widely used medications for depression. Common SSRIs include:

Serotonin and norepinephrine reuptake inhibitors 

SNRIs increase levels of the brain chemicals serotonin and norepinephrine. Common SNRIs include:

Serotonin modulators

Serotonin modulators are a class of drugs that work by increasing levels of serotonin in the brain or directly stimulating or blocking serotonin receptors. 

Atypical antidepressants

Atypical antidepressants are a class of drugs that may affect multiple neurotransmitters, including serotonin, dopamine and norepinephrine. These may work in different ways to regulate mood and treat depression. The most commonly used atypical antidepressants are:

Tetracyclic and tricyclic antidepressants

Tetracyclic and tricyclic antidepressants (TCAs) were once considered a first-line treatment for depression, but are now mostly used for hard-to-treat or treatment-resistant depressive symptoms. These are less commonly used since they tend to have more side effects and more interactions with other medications. They work to increase serotonin and norepinephrine in the brain. The most commonly used are:

Monoamine oxidase inhibitors

MAOIs can have severe side effects, so they are rarely used. Due to potential drug interactions, they should never be taken in combination with SSRIs, certain seizure medications, and many other types of medications. MAOIs include: While antidepressant medications help many people, up to 30% of people taking antidepressants do not improve or experience a short-lived improvement. In some cases, other medications may be recommended for treatment-resistant depression.

Researchers have been working with the medication ketamine. This medication was first developed as an anesthetic agent for various surgical or diagnostic procedures. However, it may also be used to reduce depressive symptoms. 

The medication Esketamine (ketamine) was approved by the Food and Drug Administration (FDA) in March 2019 and is available as a nasal spray. In one study, 70% of patients using an oral antidepressant and Esketamine improved compared to just over half of the control group. 

However, the U.S. Food and Drug Administration (FDA) created a Risk Evaluation and Mitigation Strategy (REMS) due to the potential risks of using the drug. A REMS is a drug safety program that the FDA requires for specific medications with serious potential safety issues to help ensure that the benefits of using the drug outweigh its risks.

What is the best medication for depression?

There are many treatments for depression, but there is no "best" medication. What works for one person might not work for another since everyone reacts differently to medicines. Your doctor will take your medical condition, medical history, and other medications you are taking into consideration when suggesting a treatment for you. 

Be sure to speak with your doctor about potential side effects and drug interactions with other medications you might be taking. All antidepressants carry a Boxed Warning, often called a “black box warning,” designed to call attention to serious or life-threatening risks. The specific Boxed Warning cautions that antidepressants may increase the risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder or other psychiatric disorders.

What are common side effects of depression medications?

As with all medications, antidepressants may cause undesired responses to the medication. While these side effects often diminish within a few weeks of use, some may persist for longer.

Consult your doctor about the risks and benefits of a particular medication. Many people find the benefits outweigh the risks; however, some people find it challenging to tolerate some side effects. You should always seek medical advice before stopping a medication. 

Common side effects of selective serotonin reuptake inhibitors (SSRIs) may include:

Serotonin syndrome

In addition to these side effects, many antidepressants may carry a risk of serotonin syndrome, which occurs when the level of serotonin rises to a dangerous level. It is rare and typically happens when combining antidepressants or medications that increase serotonin levels. For example, taking the herbal supplement St. John’s Wort may increase the risk of serotonin syndrome when taking it with another antidepressant. Symptoms of serotonin syndrome may include:
  • Anxiety
  • Confusion
  • Agitation
  • Sweating
  • Muscle twitching or spasm
  • Shivering, shaking, or trembling
  • Diarrhea
  • Fever
  • Increased heart rate
  • Rapid eye movements
  • Vomiting
If you experience these symptoms while taking an antidepressant, you may need to seek immediate medical attention. 

Depression treatment without medication

Exercise

Besides the physical benefits, such as protecting against heart disease or diabetes, improving sleep, and lowering blood pressure, exercise may also help improve emotional and mental health. High-intensity exercise can cause the brain to release endorphins, which are considered the feel-good chemicals, according to Harvard Health. Low-intensity activity sustained over time may also offer benefits. When you exercise, your body releases neurotrophic or growth factor proteins, which may lead to new connections between nerve cells and improved brain function.

Meditation

Meditation may help decrease depressive symptoms, according to John Hopkins Medicine. Madhav Goyal, M.D., reviewed 47 studies on meditation and found that it “appeared to provide as much relief from some depression symptoms as other studies have found with antidepressants.” Mindfulness meditation, which involves focusing on the present moment, was found to be most effective. Goyal believes that regular meditation can help reduce the worries and fears that accompany depression. 

Diet

What you eat may also affect symptoms of depression. A study published in 2017 found that eating a modified Mediterranean diet, which is high in vegetables, fruits, whole grains, fish, legumes, nuts, and extra virgin olive oil, improved mental health. The results found that around 30% of those who ate a healthy diet achieved remission from major depression. Only 8% of those in the control group experienced an improvement in depression symptoms. 

Sleep Hygiene

Getting adequate sleep may be helpful in managing episodes of depression. Studies have shown that individuals who improved their sleep quality experienced a significant reduction in depression symptoms, positively affecting their daily life. Healthy sleep hygiene habits may include keeping a consistent sleep schedule, avoiding electronic devices before bed, and creating a comfortable resting environment. 

Social support 

Social support in the form of assistance and emotional or physical comfort from friends and family may also have a positive impact on symptoms of depression. One study found that individuals with depression who received strong social support, such as from family members, were more likely to see improvements in their condition. Therefore, being able to depend on a strong network for support from others may be beneficial for mental well-being.

Natural treatments – herbs and supplements

St. John’s Wort – A review of studies, which looked at 35 studies with 6,993 participants, found that St. John’s Wort is more effective than a placebo and may be similarly effective to antidepressant medication for people with mild to moderate depression. However, St. John’s Wort may cause adverse effects and be linked to drug interactions that may increase the risk of serotonin syndrome. 

Chamomile – A small study in 2012 found that chamomile may provide more relief from depression than a placebo. However, this study was small, with only 57 participants. Further studies are needed before determining the benefits of this herbal supplement for treating depression. 

Saffron – Saffron might be an effective way of managing symptoms of depression and anxiety, according to a review of studies published in 2018. The herb may have antidepressant effects with fewer side effects than conventional antidepressants. However, more research is needed to confirm its effects.

Omega-3 fatty acids – Omega-3 fatty acids, found in fatty fish, walnuts, and flaxseeds, have been linked to improvements in depression symptoms. Omega-3 fatty acid supplements may be a potential option for managing depression alongside other treatments. One analysis of 26 different studies found that omega-3 fatty acids may help improve depression symptoms

Finding the right depression treatment

Finding the right treatment for depression starts with getting a proper diagnosis, which may include various medical tests done by your doctor or a mental health specialist. After a diagnosis, you may work closely with your healthcare provider, who will consider things like the type of depression you have, whether you have any other mental health issues, and the medical history of you and your family.

A healthcare provider will work with you to create an appropriate treatment plan. This plan might include different options, such as talk therapy, medication, and lifestyle changes. For example, cognitive therapy, dialectical behavior therapy, and interpersonal therapy are forms of talk therapy that may be useful in treating depression. In addition, you may be recommended medication, which can include different types of antidepressants.

In many cases, finding the right depression treatment can involve a process of trial and error. You might find that a particular treatment option is not working to relieve your symptoms after some time. However, various treatment options are available, and it’s normal to work with a healthcare provider in trying different options to find the one that works for you. 

Frequently asked questions about depression

What are the different types of depression medications?

There are several types of antidepressants available. First-line treatments for depression include second-generation antidepressants, such as SSRIs, SNRIs, and atypical antidepressants. Older antidepressants, which tend to have more side effects or drug interactions, include tetracyclic antidepressants, tricyclic antidepressants, and MAOIs. Esketamine is a relatively new medication that was approved by the FDA in 2019 and is classified as an NMDA antagonist. 

Are stimulants used to treat depression?

Stimulant medications, such as Ritalin or Adderall, are not considered a first-line treatment for depression. However, they may be prescribed off-label as an add-on treatment for people who have not had an adequate response to antidepressants alone. Stimulants might help with certain depressive symptoms, such as fatigue, loss of energy, and impaired concentration. 

What is the most popular antidepressant? What are the common antidepressants?

SSRIs are the most commonly prescribed types of antidepressants. Some common SSRIs include Prozac (fluoxetine), Zoloft (sertraline), Celexa (citalopram), Paxil (paroxetine), and Lexapro (escitalopram).

What is the best depression medication without side effects?

All antidepressants have the potential to cause side effects. However, everyone reacts to medication differently, so what works for one person might not work for another. Not everyone may experience side effects, and those that do can experience them differently. 

What is the best natural antidepressant?

While there are many natural remedies that people use to help manage depression symptoms, there is no single "best" natural antidepressant that works for everyone. Lifestyle changes, such as a healthy diet and regular exercise, may help naturally reduce symptoms of depression. In addition, some natural remedies that have been studied for their potential antidepressant effects include St. John's wort, omega-3 fatty acids, and saffron. It’s important to consult a healthcare provider before trying an herbal remedy for depression due to potential side effects and drug interactions. 

What is the best method to treat depression?

The most appropriate method to treat depression will depend on different factors, such as the severity of symptoms, possible causes, risk factors, and the individual’s medical history. For example, certain treatments may be tailored to specific types of depression, such as seasonal affective disorder or premenstrual dysphoric disorder. In general, a combination of talk therapy and medication has been shown to be effective in treating major depression. For those with mild depression or specific situations, such as pregnant women or older adults, lifestyle changes and specific adjustments in treatment may be recommended. 

How do antidepressants work?

Antidepressants are believed to work by balancing certain chemicals or neurotransmitters in the brain. For example, people with depression might have low serotonin, norepinephrine, or dopamine levels. Antidepressants may work in different ways to increase the levels of these neurotransmitters and improve symptoms.

Which type of therapy is often used to treat depression?

Cognitive-behavioral therapy (CBT) is a common psychotherapy used to treat depression. This therapy focuses on identifying negative thought patterns and replacing them with healthy, balanced thought patterns. CBT also provides practical solutions for problem-solving and creating steps to take after noticing early signs of a depressive episode. 

Do I need a psychiatrist or psychologist?

Some people may be treated for depression by their primary physician. However, you may be referred to a psychologist or psychiatrist for further evaluation and treatment, depending on the severity of your symptoms. Psychiatrists are medical doctors who primarily treat mental health disorders with medication, while psychologists focus on psychotherapy and other techniques for treating mental illness.

What do doctors do for anxiety?

The treatment used for anxiety disorders may be similar to that used for depression. A healthcare provider may recommend psychotherapy, medication, or both for anxiety. Antidepressants, like SSRIs and SNRIs, may help treat anxiety and depression. Lifestyle changes and mindfulness practices may also be recommended to help improve anxiety symptoms.
