What is depression?

Normal sadness is different from depression. It's normal to feel sad after upsetting events like the death of a loved one, moving to a new town, fighting with a good friend or even a bad test score.

Depression involves feeling helpless, lost and hopeless for more than two weeks. Symptoms of depression include:

• Extreme sadness without cause
  
• Feeling very tired or lazy
  
• Not liking activities that were once enjoyable
  
• Putting distance between friends and family
  
• Anger, fear or anxiety
  
• Insomnia (not being able to fall asleep)
  
• Sleeping too much
  
• Unexplained change in appetite or weight
  
• Lower grades
  
• Not going out with friends as much
  
• Trouble concentrating
  
• Feeling impatient
  
• Feeling useless
  
• Causing self injury
  
• Thoughts of suicide or death

If any of these symptoms are present for more than two weeks, the person may be depressed and should seek professional help.

What causes depression?

Depression can be caused by many things. Below are some of the causes of depression:

• Genetics (runs in families)
  
• Loss of someone or something
  
• Big life changes
  
• Medical problems
  
• Violence or bad living situation
  
• Alcohol or drugs

While depression can run in families, a person won't necessarily suffer depression just because another family member has experienced it. Genetics is just one factor, and someone without any depression in his or her family history can also become depressed.

What happens in depression?

A chemical imbalance in the brain causes depression. Neurotransmitters, which transmit (send and receive) brain signals, can affect mood. Depression occurs when there are not enough of the neurotransmitters that regulate mood. There are medications that balance the neurotransmitters to treat depression.

What are the types of depression?

There are three main types of depression.

1. Major depression: severe depression that comes and goes
   
2. Dysthymia: long-lasting depression, but not as severe as major depression
   
3. Adjustment disorder with depressed mood: a reaction to a loss or change with a more serious reaction than average

Another type of depression is seasonal affective disorder (SAD), a depression that comes and goes with the seasons.

Another condition called bipolar disorder involves a pattern of very good moods and high energy (mania) and very bad moods (depression). These changes of mood can happen almost instantly or be more gradual. The moods can last anywhere from hours to months. It can seem like a person has two different personalities, and people close to that person never know what to expect.

What treatments exist for depression?

There are three major treatments: talking to a therapist, taking medication or a combination of both. If you think you are depressed, talk to an adult who can help you figure out which treatment might be best for you.

In some bad cases, depression can cause people to think about injuring or killing themselves. If you know someone who has expressed these types of feelings, tell an adult right away. The person should get help immediately from a professional.

You may feel frustrated that you cannot cheer up someone who is depressed on your own. Remember that depression is a serious problem requiring professional treatment.
