Understanding Depression
Depression is more than just feeling sad. People who are clinically depressed are not just moody or feeling “blue” for a few days. They experience long periods of feeling very down—or in some cases, very anxious or extremely tired—for several weeks or months. Drug and/or alcohol abuse may also be signs of depression. Because depression can change the way a person feels, thinks, and behaves, it can have negative effects on all aspects of a person’s life, from school, to work, to family and social life.

What Depression Isn’t
Depression is often misunderstood or unrecognized. Depression is not a sign of a weak personality, nor is it something to be ashamed of. It is a real disease, like HIV, diabetes, or arthritis – one that needs treatment. The good news is that depression can be treated effectively. Medications such as LEXAPRO® are available through a doctor or healthcare professional and have been proven to relieve depression in many people. Read more about treatments for depression.
What Causes Depression?
In addition to external, societal factors that may contribute to depression, there are other reasons why a person might become depressed. These include traumatic life experiences such as the death of a loved one, living with disease, taking medications with unpleasant side effects, substance abuse, hormonal changes, or a family history of depression. Sometimes the cause of depression is unknown.
Whatever the circumstances, depression is caused by an imbalance of certain chemicals in the brain. Normally, these "chemical messengers" help nerve cells communicate with one another by sending and receiving messages, and they may also influence a person's mood. In the case of depression, the available supply of the chemical messengers is low, so nerve cells can't communicate effectively.
Antidepressant medications such as LEXAPRO work by helping to correct the imbalance of chemicals in the brain. These medications may take several weeks to be effective, but they work well and are generally safe. With just one 10 mg tablet a day, LEXAPRO significantly improves the symptoms of depression and anxiety for many patients beginning at week 1 or 2, although it may take 4 to 6 weeks to feel the full antidepressant effect.
