Read this section, which reviews psychological disorders commonly diagnosed in childhood. While children can have similar mental health problems that adults have, like anxiety or depression, children may have difficulty with changes associated with growing up, such as beginning school.

Even when children do have problems that also appear in adults, the problem tends to look different in a child. Think about the differences and similarities in childhood psychological problems as those compared with adults.
