How can I determine if my 10 year old child has depression?

Child Psychiatry. A full evaluation by a child psychiatrist is indicated. Children exhibit different symptoms of depression than adults. For example, irritability may be more pronounced.
Ask your child. There are signs such as loss of interest, changes in eating , sleeping and school habits that are seen with depression but in a 10 year old you should simply ask your child if he/she feels sad and if so, about what.
Child issues. children who are depressed often show persistent irritability, withdrawal from social interaction, poor performance in school, decrease or increase in appetite.
