Everyone occasionally feels sad or down, but often these feelings pass within a couple of days. When a person is experiencing depression, however, the condition interferes with daily life and functioning. Depression is a serious condition, and many people benefit from professional treatment and support to recover.

The most common types of depression include:

Major depression, also known as clinical depression, is characterised by a combination of symptoms that interfere with the ability to work, sleep, eat, and enjoy life during the same two-week period. An episode of major depression may occur only once or twice, but more often, a person has several episodes (recurrent depression). If the pattern is seasonal, it will be what is commonly known as seasonal affective disorder.

Persistent depressive disorder (dysthymia) involves chronic symptoms that last for two years or more. Since depressive symptoms may be consistent in the person’s daily life, they may think this is just who they are. They may keep a person from functioning at “full steam” or from feeling good when being social or working, for example. Sometimes people with persistent depressive disorder also experience major depressive episodes.

Premenstrual dysphoric disorder is a significant change in mood, with depression and anger that begins a week before a woman’s period, and which starts to improve after the beginning of the period or becomes minimal in the week post period.

Post-natal depression is diagnosed when a new mother has a major depressive episode within one month to a year after giving birth.

Symptoms of depression

People who are depressed may not display all symptoms of the condition. Some people experience a few symptoms, and some have many. The frequency and severity of symptoms may vary from one person to the next.

Symptoms of depression include the following:

• persistent sad, anxious, or “empty” moods
• feelings of hopelessness or pessimism
• feelings of guilt, worthlessness, or helplessness
• loss of interest or pleasure in hobbies and once-enjoyed activities, including sex
• sleeping difficulties, such as trouble falling asleep, staying asleep, or excessive sleeping
• eating too much or too little
• fatigue, lack of energy, or feeling “slowed down”
• restlessness or irritability
• difficulty concentrating, remembering, or making decisions
• persistent physical symptoms that do not respond to treatment, such as headaches, digestive issues, and chronic pain
• thoughts of death or suicide, or self-harm or suicide attempts

Causes of depression

Depression has no single cause. It may result from a combination of genetic, biochemical, environmental, and psychological factors. For example, some types of depression tend to run in families, but depression can also occur with no family history at all. A difficult experience, such as the death of a loved one, could trigger a depressive episode as well.

Treatment options

Treatment options Most people with depression—even those with severe symptoms—can be helped with treatment. Effective treatment begins with visiting your GP to rule out medical causes of the problem. If they find no disease or other medical condition that may be causing the depression, the next step is a psychological evaluation. The doctor may refer you to a mental health professional, who will talk further with you about your symptoms.

Once you have a diagnosis, treatment can proceed in several ways. The most common types of treatments use medicines and psychotherapy, or both.

Medicines. A doctor may prescribe antidepressants or other medicines that may be helpful. Many people have concerns about taking medicines. Changes in brain chemistry, stress hormones, and neural networks can all play a role in depression, among other biological and environmental factors. Just as people with other health conditions may need medication to restore balance, some people with depression benefit from antidepressants as part of their treatment plan. Yet there is often a stigma around taking medicines for depression. It is important to work with your doctor to determine the best medicine for you and your specific needs. You may need to try a few different ones in the beginning, all while working with your doctor until you find the one that works best for you.

Antidepressant medicine

Antidepressants work with natural brain chemicals known as neurotransmitters, such as serotonin, norepinephrine, or dopamine. Antidepressants include:

• Selective serotonin reuptake inhibitors (SSRIs) and serotonin and noradrenaline reuptake inhibitors (SNRIs). SSRIs affect a brain chemical called serotonin, and SNRIs affect two chemicals, serotonin, and noradrenaline. SSRIs are often the first type of antidepressant that a doctor will recommend, in part because they often cause fewer side effects than other types.
  
  
• Atypical antidepressants. Some antidepressants are called “atypical” because they work differently than SSRIs or SNRIs. One commonly prescribed atypical antidepressant is bupropion, which is used both to treat depression and to prevent depression in people with seasonal affective disorder. Other medications in this category include trazodone and mirtazapine.
  
  
• Tricyclics. Tricyclics are an older group of antidepressants and are named for their chemical structure. They may be prescribed for people who can’t take SSRIs or SNRIs or for whom those types of medication don’t work well.
  
  
• Monoamine oxidase inhibitors (MAOIs). MAOIs are the oldest class of antidepressants, and for some people they work better than other medications. But people who take them must avoid certain foods and drinks, such as cheese, fermented foods, and red wine.
  

A doctor may need to try a variety of antidepressants and adjust the dosage to find one that works for you.

If antidepressants are prescribed for you

Take these steps if an antidepressant is prescribed for you:

Ask about the side effects. Also, find out about any testing that may be needed to monitor the effects of the medication on your body.

Be patient. Finding the right medicine can take time. Work closely with your doctor and report any side effects and benefits you experience.

Always talk to your doctor before stopping any medicine, even if you feel better. Some medicines must be stopped gradually to give your body time to adjust. If you have chronic major depression, you may need to take a medicine daily to avoid disabling symptoms.

If you are taking MAOIs, be aware of the restrictions. Remember to avoid fermented foods, including cheeses, wines, and pickles. Get a complete list of foods to avoid, and always carry it with you.

Never mix medicines—prescribed, over the counter, or borrowed—without talking to your doctor. If your dentist or any other medical professional prescribes a drug, tell them that you are taking antidepressants. Some drugs that are safe when taken alone can be dangerous if taken with other medications.

Try to limit or avoid alcohol. Alcohol can interfere with antidepressant effectiveness and mood.

Call your GP if you have a question. Reach out to your doctor anytime about any drug or if you are having a problem that you believe is drug-related. Your questions and concerns are important.

Antidepressants may increase the risk of suicidal thoughts in children, adolescents, and young adults. People in all three groups need to be monitored closely by health professionals if they take antidepressants, especially in the first weeks of treatment.

Psychotherapy, or “talk therapy.” Psychotherapy is a form of treatment that can help a person enhance problem-solving skills, manage feelings of anxiety and depression, build relationships and social skills, and even improve job performance. Research shows that psychotherapy can be effective in treating the most common mental health problems.

Therapists often draw on different forms of psychotherapy, tailoring treatment to the needs of a client. No one form of psychotherapy is best for everybody. Therapies like cognitive behavioural therapy (CBT), interpersonal, psychodynamic, and “third wave” therapies such as dialectical behaviour therapy (DBT), have all been shown to be effective in managing depressive symptoms. However, the level of comfort and trust between the client and the therapist is often more important than the type of psychotherapy used.

Severe or recurring depression often benefits from both medication and psychotherapy. Complementary approaches—such as exercise, mindfulness, or improved sleep—can also support overall wellbeing.

Skills and actions to manage symptoms of depression

If there is a possibility you are experiencing depression, try to see a medical professional as soon as possible. Some research suggests that the longer you wait, the more problems you may have later. You can also help yourself by taking these steps:

Try behavioural activation. Do things you’ve enjoyed in the past, like going to the cinema or a sports event or walking in your favourite park. Take part in social, religious, and other activities that have had meaning for you.

Set goals you can achieve. Focus on what’s realistic for you to accomplish, not on what you or others think you “should” accomplish.

Break large tasks into small ones and set priorities. Do what you can, as you can. Tell yourself you will work on the task for 10 or 15 minutes. Then if you want to work longer, that’s great.

Keep your expectations realistic. Expecting too much too soon may increase feelings of failure if you fall short. Give yourself credit for what you have accomplished, even if that seems small.

Put off major life decisions, such as whether to change jobs, get married, or get divorced, until you feel better. If you need to make a big decision, talk it over with people you trust and know well.

Expect to improve gradually, not overnight. Don’t assume you can “snap out of” depression or see progress straight away. Improvement often occurs in small, meaningful steps and with support.

Remember that you can reframe your negative thinking with more realistic thoughts. Negative thinking is part of depression. It can ease as your depression responds to treatment.

Steps to take in finding help and support

Steps to take in finding help and support If you aren't sure where to turn for help with depression, start by talking to your GP. You can access mental health services through your GP, who can create a Mental Health Treatment Plan, or through self-referral to certain services.

Others who can provide help and support, or referrals, include: 

Mental health professionals. Psychiatrists, psychologists, social workers, and clergy members who have special training in counselling can provide different kinds of support. You can also contact your organisation’s assistance programme (or EAP) for support and resources.

Community resources. You can find community mental health support through local mental health services and helplines, or by contacting your GP for referrals to appropriate resources.

Support groups. You can find community mental health support groups and local mental health services, or visit your GP, who can refer you to nearby support networks and peer groups.

Your personal support network. Talk with trusted friends or relatives and try to avoid becoming isolated.

If you feel suicidal

Seek help straight away if your depression is causing you to think of hurting yourself or someone else. For immediate help:

Call your emergency line or go to a hospital. Ask a friend or relative to help you do these things if you can't do them yourself. Hospitals and emergency departments have mental health professionals on staff. If you need an immediate evaluation, this is the quickest way to be seen by a professional.

Call your GP. Be honest and upfront. Your doctor can only help you based on the information you share. You should tell them how you have been feeling and what you have been thinking.
