Depression doesn't just affect adults. Children and teenagers can get depressed too.
Some studies show that almost one in four young people will experience depression before they are 19 years old.
It's important to get help early if you think your child may be depressed. The longer it goes on, the more likely it is to disrupt your child's life and turn into a long-term problem.
Symptoms of depression in children often include:
Your child may also:
Some children have problems with anxiety as well as depression. Some also have physical symptoms, such as headaches and stomach aches.
Problems at school can be a sign of depression in children and teenagers and so can problem behaviour, especially in boys.
Older children who are depressed may misuse drugs or alcohol.
Things that increase the risk of depression in children include:
Sometimes depression is triggered by one difficult event, such as parents separating, a bereavement or problems with school or other children.
Often it's caused by a mixture of things. For example, your child may have inherited a tendency to depression and also have experienced some difficult life events.
If you think your child may be depressed, it's important to talk to them. Try to find out what's troubling them and how they are feeling.
Whatever is causing the problem, take it seriously. It may not seem a big deal to you, but it could be a major problem for your child.
If your child doesn't want to talk to you, let them know that you are concerned about them and that you're there if they need you.
Encourage them to talk to someone else they trust, such as another family member, a friend or someone at school.
It may be helpful for you to talk to other people who know your child, including their other parent.
You could also contact their school to see if they have any concerns.
If you think your child is depressed, make an appointment with them to see your GP.
If necessary they can refer your child to their local child and adolescent mental health service (CAMHS) for specialist help.
