An Overview of Depression

Everyone feels blue now and then. It's part of life. But if you no longer enjoy activities that you usually like, you may have a more serious problem. Being depressed, without letup, can change the way you think and feel. Doctors call this "clinical depression."

Being "down in the dumps" over a period of time is not a normal part of getting older. But it is a common problem, and medical help may be needed. For most people, depression will get better with treatment. "Talk" therapy, medicine, or other treatment methods can ease the pain of depression. You do not need to suffer.

There are many reasons why depression in older people is often missed or untreated. As a person ages, the signs of depression are much more varied than at younger ages. It can appear as increased tiredness, or it can be seen as grumpiness or irritability. Depression can be tricky to recognize in older adults. Confusion or attention problems caused by depression can sometimes look like Alzheimer's disease or other brain disorders.

Mood changes and signs of depression can be caused by medicines older people may take for arthritis, high blood pressure, or heart disease. It can be hard for a doctor to detect depression. The good news is that people who are depressed usually feel better with the right treatment.

What Causes Depression?

There is no one cause of depression. For some people, a single event can bring on the illness. Depression often strikes people who felt fine but who suddenly find they are dealing with a death in the family or a serious illness. For some people, changes in brain chemistry can affect mood and cause depression. Sometimes those under a lot of stress, like caregivers, can feel depressed. Others become depressed for no clear reason.

People with serious illnesses, such as cancer, diabetes, heart disease, stroke, or Parkinson's disease, sometimes become depressed. They worry about how their illness will change their lives. They might be tired and not able to deal with something that makes them sad. Treatment for depression helps them manage their depressive symptoms and improves their quality of life.

Genetics, too, can play a role. Studies show that depression may run in families. Children of depressed parents may be at a higher risk for depression. And, depression tends to be a disorder that occurs more than once. Many older people who have been depressed in the past will be at an increased risk.

What to Look For

How do you know when you need help? After all, as you age, you may have to face problems that could cause anyone to feel "depressed." Perhaps you are dealing with the death of a loved one or friend. Maybe you are having a tough time getting used to retirement and you feel lonely. Possibly you have a chronic illness. Or, you might feel like you have lost control over your life.

After a period of feeling sad, older people usually adjust and regain their emotional balance. But, if you are suffering from clinical depression and don't get help, your depression might last for weeks, months, or even years. Here is a list of the most common signs of depression. If you have several of these, and they last for more than 2 weeks, see a doctor.
