What is depression?
Depression is an illness that causes you to feel sad, lose interest in activities that you've always enjoyed, withdraw from others, and have little energy. It's different from normal feelings of sadness, grief , or low energy. Depression can also cause people to feel hopeless about the future and even think about suicide.
Many people, and sometimes their families, feel embarrassed or ashamed about having depression. Don't let these feelings stand in the way of getting treatment. Remember that depression is a common illness. It affects the young and old, men and women, all ethnic groups, and all professions.
If you think you may be depressed, tell your doctor. Treatment can help you enjoy life again. The sooner you get treatment, the sooner you will feel better.
What causes depression?
Depression is a disease. It's not caused by personal weakness and is not a character flaw. When you have depression, chemicals in your brain called neurotransmitters are out of balance.
Most experts believe that a combination of family history (your genes) and stressful life events may cause depression. Life events can include a death in the family or having a long-term health problem.
Just because you have a family member with depression or have stressful life events doesn't mean you'll get depression.
You also may get depressed even if there is no reason you can think of.
What are the symptoms?
The symptoms of depression may be hard to notice at first. They vary among people, and you may confuse them with just feeling "off" or with another health problem.
The two most common symptoms of depression are:
A serious symptom of depression is thinking about death or suicide. If you or someone you care about talks about this or feeling hopeless, get help right away.
If you think you may have depression, take a short quiz to check your symptoms:
How is it treated?
Depression can be treated in various ways. Counseling, psychotherapy, and antidepressant medicines can all be used. Lifestyle changes, such as getting more exercise, also may help.
Work with your health care team to find the best treatment for you. It may take a few tries, and it can take several weeks for the medicine to start working. Try to be patient and keep following your treatment plan
Depression can return (relapse). How likely you are to get depression again increases each time you have a bout of depression. Taking your medicines and continuing some types of therapy after you feel better can help keep that from happening. Some people need to take medicine for the rest of their lives. This doesn't stop them from living full and happy lives.
What can you do if a loved one has depression?
If someone you care for is depressed, the best thing you can do is help the person get or stay in treatment. Learn about the disease. Talk to the person, and gently encourage him or her to do things and see people. Don't get upset with the person. The behavior you see is the disease, not the person.

Who to see
Your family doctor can help you with depression. If treatment by your doctor doesn't help you, the next step is to see a mental health professional.
No matter who you see, it is important that this person has experience treating people with depression and is trained in proven therapies. It is also important that you establish a good long-term relationship. If you don't feel comfortable with one doctor or therapist, try another one.
Health professionals who can diagnose depression and prescribe medicine include:
Treatment such as professional counseling or therapy can be provided by:
Other health professionals who also may be trained in treating depression include:
Exams and Tests
Depression may be diagnosed when you talk to your doctor about feeling sad or when your doctor asks you questions and discovers that you are feeling sad. You may be seeing your doctor because you feel sad or because you have another health problem or concern.
If your doctor thinks you are depressed, he or she will ask you questions about your health and feelings. This is called a mental health assessment. Your doctor also may:

Little is known about how to prevent depression, but getting exercise and avoiding alcohol and drugs may help. Exercise may also help prevent depression from coming back (relapse) and may improve symptoms of mild depression.
You also may be able to prevent depression by avoiding alcohol and drugs. Alcohol and drugs can trigger depression. And using them is often a sign that you have depression.
Preventing depression from coming back
You may be able to prevent a relapse or keep your symptoms from getting worse if you:
Counseling and psychotherapy are important parts of treatment for depression. You will work with a mental health professional such as a psychologist, licensed professional counselor, clinical social worker, or psychiatrist. Together, you will develop an action plan to treat your depression.
When you hear "counseling" or "therapy," you may think of lying on a couch and talking about your childhood. But most of these treatments don't look for hidden memories. They deal with how you think about things and how you act each day.
The first step is finding a therapist you trust and feel comfortable with. The therapist also should have experience treating people who have depression and should be trained in proven therapies. These therapies include: 3
Some therapists use acceptance and commitment therapy (ACT). In ACT, you work with a therapist to learn to accept your negative feelings but not let them run your life. You learn to make choices and act based on your personal values, not negative feelings.
Mindfulness strategies are another type of therapy. They seek to focus your attention on what is happening at the moment without trying to change it. These strategies teach you to let go of past regrets and not worry about the future. They may help with depression in some people.
Other treatments you may have heard of include problem-solving therapy , which looks at your current problems and helps you solve them, and family therapy , which brings you and your family together to discuss your relationships and depression. Experts don't know how well these therapies work for depression. 3
How long will you need therapy?
How long your treatment lasts depends on how severe your depression is and how well you respond to treatment. Short-term counseling or therapy usually lasts from 10 to 20 weeks, and you usually see your mental health professional once a week. But you may need to meet with your health professional more often or for a longer time.
Antidepressant medicines may improve or completely relieve the symptoms of depression. If you are mildly depressed, you may not have to take them, but most people with moderate or severe depression need medicine.
Antidepressant medicines work in different ways. No antidepressant works better than another, but different ones work better or worse for different people. The side effects of antidepressant medicines are different and may lead you to choose one instead of another.
You may have to try different medicines or take more than one to help your symptoms. Most people find a medicine that works within a few tries. Other people take longer to find the right one and may need to take the antidepressant and another type of medicine, such as an antiseizure, mood stabilizer, antipsychotic, or antianxiety medicine.
Together you and your doctor will decide if you need medicine, what things you'll need to think about if you need medicine, and which medicine is right for you.
Antidepressant medicines include:
Side effects and safety
Antidepressant medicines have side effects. You may notice the side effects before you notice that the medicine is helping you. Side effects vary depending on the medicine you take.
People who are taking medicines for other health problems need to know about medicine interactions. Talk with your doctor about the best way to track whether a combination of medicines is harming you. People who are taking a lot of medicines also are more likely to have harmful side effects.
How long will you need medicines?
If you take antidepressants, you should take them for at least 6 months after you begin to feel better. This can help prevent you from feeling depressed again (relapse). If this isn't the first time you have been depressed, your doctor may want you to take these medicines even longer.
You may start to feel better within 1 to 3 weeks after starting your antidepressant medicine. But it can take as many as 6 to 8 weeks to see a great deal of improvement. If you have questions or concerns about your medicines, or if you don't notice that you feel better by 3 weeks, talk to your doctor.
Some people need to remain on medicine for several months to years. Others will need medicine long-term. This is more likely if you have had several bouts of depression that seriously affected your home life, work life, or both.
Don't quit taking your medicines without talking to your doctor. If you quit suddenly, it can cause dizziness, anxiety, fatigue, and headache. If you and your doctor decide you can quit using medicine, gradually reduce the dose over several weeks.
Living With Depression
When you're going through depression, you can't just shake it off. You might have a couple of good days followed by a bad day or a string of bad days. And you don't know how long it will last. Depression isn't like the flu or a sprained ankle, where your doctor can tell you about how long it will take to get better.
When you're getting better, many experts call it recovery. Recovery is finding your path to the life you care about.
During your recovery, be patient and kind to yourself. Remember that depression isn't your fault and isn't something you can overcome with willpower alone. You need treatment for depression, just like for any other illness.
Continuing your treatment, helping yourself, getting support, and having a healthy lifestyle are all part of your recovery. Your symptoms will fade as your treatment starts to work. Don't give up. Focus your energy on getting better. Your mood will improve. It just takes some time.
You can take many steps to help yourself when you feel depressed or are waiting for your medicine to work. These steps also help prevent depression from coming back.
You also can help yourself by thinking about what is good in your life. You can:
Remember the basics
Electroconvulsive therapy (ECT) may be used to treat severe depression or depression that doesn't get better with medicine and counseling or therapy.
Other types of brain stimulation have not been well studied and may be expensive. They usually are considered only if other treatment doesn't work. They include:
Complementary therapies are sometimes used for depression. Always tell your doctor if you are using any of them. These therapies include:
For Family and Friends
If someone you care about is depressed, you may feel helpless. Maybe you're watching a once-active or happy person slide into inactivity, or you're seeing a good friend lose interest in favorite activities. The change in your loved one's or friend's behavior may be so big that you feel you no longer know him or her.
