Depression Overview

Common Causes of Depression

If you're depressed, it might not be easy to figure out why. In most cases, depression doesn't have a single cause. Instead, it results from a mix of things -- your genes, events in your past, your current circumstances, and other factors.

Here are a few of the things that can play a role in causing depression.

  • Biology. We still don't know exactly what happens in the brain when people become depressed. But studies show that certain parts of the brain don't seem to be working normally. Depression might also be affected by changes in the levels of certain chemicals in the brain, called neurotransmitters.
  • Genetics. Researchers know that if depression runs in your family, you have a higher chance of becoming depressed.
  • Gender. Studies show that women are about twice as likely as men to become depressed. No one's sure why. The hormonal changes that women go through at different times of their lives may be a factor.
  • Age. People who are elderly are at higher risk of depression. That can be compounded by other factors -- living alone and having a lack of social support.
  • Health conditions. Conditions such as cancer, heart disease, thyroid problems, chronic pain, and many others increase your risk of becoming depressed.
  • Trauma and grief. Trauma, such as violence or physical or emotional abuse -- whether it's early in life or more recent -- can trigger depression. So can grief after the death of a friend or loved one.
  • Changes and stressful events. It's not surprising that people might become depressed during stressful times -- such as during a divorce or while caring for a sick relative. Yet even positive changes -- like getting married or starting a new job -- can sometimes trigger depression.
  • Medications and substances. Many prescription drugs can cause symptoms of depression. Alcohol or substance abuse is common in depressed people. It often makes their condition worse.

Some people have a clear sense of why they become depressed. Others don't. The most important thing to remember is that depression is not your fault. It's not a flaw in your character. It's a disease that can affect anyone -- and regardless of the cause, there are many good ways to treat it

To get better, you need to take an active role in your treatment. You're not just a patient. You and your doctor have to work as a team.

Of course, right now, you might not feel up to taking an active role in anything. You might have doubts that treatment will help. But push yourself. Depression can make you feel powerless. Taking charge of your treatment is one way to feel in control again.

Here are some tips.

  • Stick with it. Treatment won't work right away. Antidepressants may not take effect for four to six weeks. In some cases, a medication may not work and you'll need to try another. Therapy can take awhile, too. But don't despair. If you give them time, these treatments are very likely to help. When a depressed person gets the right medicine, at the right dose, and takes it long enough, treatment succeeds about 70% of the time. But you and your doctor may need to try quite a few treatments before landing on the right therapy for you.
  • Take your medicine as prescribed. Get into good habits. Take your medicine at the same time every day. It's easier to remember if you do it along with another activity, like brushing your teeth, eating breakfast, or getting into bed. Get a weekly pillbox, which will make it easy to see if you've missed a dose.
  • Never stop taking your medicine without your doctor's OK. If you need to stop taking a medicine for some reason, your doctor may reduce your dose gradually. If you stop suddenly, you may have side effects. Stopping medication abruptly may also cause depression to return.

Don't assume that you can stop taking your medicine when you feel better. Many people need ongoing treatment even when they're feeling well. This can prevent them from getting depressed again. Remember, if you're feeling well now, it might be because your medicine is working. So why stop?

  • Make lifestyle changes. There's a lot you can do on your own to supplement your treatment. Eat healthy foods, high in fruits and vegetables and low in sugars and fats. Make sure to get a good night's sleep. Several studies show that physical activity can help with the symptoms of depression. Start slowly. Try taking walks around the neighborhood with a friend. Gradually, work up to exercising on most days of the week.
  • Reduce stress at home and at work. Ask for help with some of the stressful things in your life. See if your friends or family will take care of some of the daily hassles, like housework. If your job is stressing you out, figure out ways to scale back some of your duties.
  • Be honest. Opening up to a therapist isn't easy. But if you're not truthful, therapy is less likely to help. If you have doubts about therapy or your therapist's approach, don't hide them. Instead, talk about them openly with your therapist. He or she will be happy to have your feedback. Together, you might be able to work out a new approach that works better.
  • Be open to new ideas. Your therapist may have suggestions that sound strange. He or she may push you to do things that feel awkward or uncomfortable. But try to stay open. Give new approaches a try. You may find them more helpful than you expected.
  • Don't give up. You may feel hopeless right now. You may feel like you're never going to get better. But feeling that way is a symptom of your condition. If you give yourself some time — and allow your treatment to take effect — you will feel better again.
