Depression is a serious mood disorder that can take the joy from a child's life. It is normal for a child to be moody or sad from time to time. You can expect these feelings after the death of a pet or a move to a new city. But if these feelings last for weeks or months, they may be a sign of depression.Experts used to think that only adults could get depression. Now we know that even a young child can have depression that needs treatment to improve. As many as 2 out of 100 young children and 8 out of 100 teens have serious depression.Still, many children don't get the treatment they need. This is partly because it can be hard to tell the difference between depression and normal moodiness. Also, depression may not look the same in a child as in an adult. When a child does not outgrow the fears and worries that are typical in young children, or when there are so many fears and worries that they interfere with school, home, or play activities, the child may be diagnosed with an anxiety disorder. Examples of different types of anxiety disorders include Being very afraid when away from parents (separation anxiety),Having extreme fear about a specific thing or situation, such as dogs, insects, or going to the doctor (phobias),Being very afraid of school and other places where there are people (social anxiety),Being very worried about the future and about bad things happening (general anxiety), Having repeated episodes of sudden, unexpected, intense fear that come with symptoms like heart pounding, having trouble breathing, or feeling dizzy, shaky, or sweaty (panic disorder) Anxiety may present as fear or worry, but can also make children irritable and angry. Anxiety symptoms can also include trouble sleeping, as well as physical symptoms like fatigue, headaches, or stomachaches. Some anxious children keep their worries to themselves and, thus, the symptoms can be missed.
