Child Mental Health

Early recognition and treatment of mental illness in children are vital, as untreated conditions can become ingrained and more difficult to manage over time.

Overview

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.

Warning Signs

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

Diagnosis & Treatment

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.

Frequently Asked Questions

Notice if the change lasts more than a few weeks, occurs in multiple settings (home, school, friends), and is accompanied by sleep or appetite shifts, social withdrawal, or self‑harm behaviors. Persistent patterns that interfere with daily functioning usually warrant a professional evaluation.
Call emergency services (911 in the U.S.) or your local crisis line immediately. Keep the child in a safe environment, remove sharp objects, and stay with them until help arrives. After the crisis, arrange a prompt appointment with a child psychiatrist or psychologist.
If symptoms are mild and improve with supportive parenting, a primary care visit may suffice. Escalate to a mental health specialist when symptoms are severe, persistent, or if you notice self‑harm, drastic mood swings, or academic decline.
Educate yourself about the medication’s purpose, dosage, and side effects. Encourage adherence by setting reminders, and monitor for changes in mood or behavior. Maintain open communication with the prescriber and involve the child in discussions about their treatment plan.
