  1. Depression

  2. Causes • Biological differences. People with depression appear to have physical changes in their brains. The significance of these changes is still uncertain but may eventually help pinpoint causes. • Neurotransmitters. These naturally occurring brain chemicals linked to mood are thought to play a direct role in depression.

  3. Causes • Hormones. Changes in the body's balance of hormones may be involved in causing or triggering depression. Hormone changes can result from thyroid problems, menopause and a number of other conditions. • Inherited traits. Depression is more common in people whose biological family members also have the condition. Researchers are trying to find genes that may be involved in causing depression.

  4. Causes • Life events. Events such as the death or loss of a loved one, financial problems and high stress can trigger depression in some people. • Early childhood trauma. Traumatic events during childhood, such as abuse or loss of a parent, may cause permanent changes in the brain that make you more susceptible to depression.

  5. Emotional Symptoms • Feeling sad, empty, hopeless, or numb. These feelings are with you most of the day, every day. • Loss of interest in things you used to enjoy. You might no longer bother with hobbies that you used to love. You might not like being around friends. You might lose interest in sex.

  6. Emotional Symptoms • Irritability or anxiety. You might be short-tempered and find it hard to relax. • Trouble making decisions. Depression can make it hard to think clearly or concentrate. Making a simple choice can seem overwhelming.

  7. Emotional Symptoms • Feeling guilty or worthless. These feelings are often exaggerated or inappropriate to the situation. You might feel guilty for things that aren't your fault or that you have no control over. Or you may feel intense guilt for minor mistakes.

  8. Emotional Symptoms • Thoughts of death and suicide. The types of thoughts vary. Some people wish that they were dead, feeling that the world would be better off without them. Others make very explicit plans to hurt themselves.

  9. Physical Symptoms • Headaches. These are fairly common in people with depression. If you already had migraine headaches, they may seem worse if you're depressed. • Back pain. If you already suffer with back pain, it may be worse if you become depressed.

  10. Physical Symptoms • Digestive problems. You might feel queasy or nauseous. You might have diarrhea or become chronically constipated. • Muscle aches and joint pain. Depression can make any kind of chronic pain worse.

  11. Physical Symptoms • Exhaustion and fatigue. No matter how much you sleep, you may still feel tired or worn out. Getting out of the bed in the morning may seem very hard, even impossible.

  12. Physical Symptoms • Change in appetite or weight. Some people with depression lose their appetite and lose weight. Others find they crave certain foods and weigh more.

  13. Physical Symptoms • Sleeping problems. Many people with depression can't sleep well anymore. They wake up too early or can't fall asleep when they go to bed. Others sleep much more than normal.
