About Child Mental Health

It's important to recognize and treat mental illnesses in children early on. Once mental illness develops, it becomes a regular part of your child's behavior. This makes it more difficult to treat.

But it's not always easy to know when your child has a serious problem. Everyday stresses can cause changes in your child's behavior. For example, getting a new brother or sister or going to a new school may cause a child to temporarily act out. Warning signs that it might be a more serious problem include:

  • Problems in more than one setting (at school, at home, with peers)
  • Changes in appetite or sleep
  • Social withdrawal or fear of things he or she did not used to be not afraid of
  • Returning to behaviors more common in younger children, such as bedwetting
  • Signs of being upset, such as sadness or tearfulness
  • Signs of self-destructive behavior, such as head-banging or suddenly getting hurt often
  • Repeated thoughts of death

To diagnose mental health problems, the doctor or mental health specialist looks at your child's signs and symptoms, medical history, and family history. Treatments include medicines and talk therapy.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Child Mental Health

806 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
