Mental illness in children: Know the signs
Date Updated: 03/02/2022
Mental illness in children can be hard for parents to identify. As a result, many children who could benefit from treatment don't get the help they need. Understand how to recognize warning signs of mental illness in children and how you can help your child.
What is a mental illness?
Mental health is the overall wellness of how you think, regulate your feelings and behave. A mental illness, or mental health disorder, is defined as patterns or changes in thinking, feeling or behaving that cause distress or disrupt a person's ability to function.
Mental health disorders in children are generally defined as delays or disruptions in developing age-appropriate thinking, behaviors, social skills or regulation of emotions. These problems are distressing to children and disrupt their ability to function well at home, in school or in other social situations.
Barriers to treating childhood mental health disorders
It can be difficult to understand mental health disorders in children because normal childhood development is a process that involves change. Additionally, the symptoms of a disorder may differ depending on a child's age, and children may not be able to explain how they feel or why they are behaving a certain way.
Other factors might also prevent parents from seeking care for a child who has a suspected mental illness. For example, parents might be concerned about the stigma associated with mental illness, the use of medications, and the cost or logistical challenges of treatment.
Common disorders among children
Mental health disorders in children — or developmental disorders that are addressed by mental health professionals — may include the following:
- Anxiety disorders. Anxiety disorders in children are persistent fears, worries or anxiety that disrupt their ability to participate in play, school or typical age-appropriate social situations. Diagnoses include social anxiety, generalized anxiety and obsessive-compulsive disorders.
- Attention-deficit/hyperactivity disorder (ADHD). Compared with most children of the same age, children with ADHD have difficulty with attention, impulsive behaviors, hyperactivity or some combination of these problems.
- Autism spectrum disorder (ASD). Autism spectrum disorder is a neurological condition that appears in early childhood — usually before age 3. Although the severity of ASD varies, a child with this disorder has difficulty communicating and interacting with others.
- Eating disorders. Eating disorders are defined as a preoccupation with an ideal body type, disordered thinking about weight and weight loss, and unsafe eating and dieting habits. Eating disorders — such as anorexia nervosa, bulimia nervosa and binge-eating disorder — can result in emotional and social dysfunction and life-threatening physical complications.
- Depression and other mood disorders. Depression is persistent feelings of sadness and loss of interest that disrupt a child's ability to function in school and interact with others. Bipolar disorder results in extreme mood swings between depression and extreme emotional or behavioral highs that may be unguarded, risky or unsafe.
- Post-traumatic stress disorder (PTSD). PTSD is prolonged emotional distress, anxiety, distressing memories, nightmares and disruptive behaviors in response to violence, abuse, injury or other traumatic events.
- Schizophrenia. Schizophrenia is a disorder in perceptions and thoughts that cause a person to lose touch with reality (psychosis). Most often appearing in the late teens through the 20s, schizophrenia results in hallucinations, delusions, and disordered thinking and behaviors.

- Avoiding or missing school
What should I do if I suspect my child has a mental health condition?
If you're concerned about your child's mental health, consult your child's health care provider. Describe the behaviors that concern you. Talk to your child's teacher, close friends, relatives or other caregivers to see if they've noticed changes in your child's behavior. Share this information with your child's health care provider.
How do health care professionals diagnose mental illness in children?
Mental health conditions in children are diagnosed and treated based on signs and symptoms and how the condition affects a child's daily life. To make a diagnosis, your child's health care provider might recommend that your child be evaluated by a specialist, such as a psychiatrist, psychologist, clinical social worker, psychiatric nurse or other mental health care professional. The evaluation might include:
- Complete medical exam
- Medical history
- History of physical or emotional trauma
- Family history of physical and mental health
- Review of symptoms and general concerns with parents
- Timeline of child's developmental progress
- Academic history
- Interview with parents
- Conversations with and observations of the child
- Standardized assessments and questionnaires for child and parents
The Diagnostic and Statistical Manual of Mental Disorders (DSM), a guide published by the American Psychiatric Association, provides criteria for making a diagnosis based on the nature, duration and impact of signs and symptoms. Another commonly used diagnostic guideline is the International Classification of Diseases (ICD) from the World Health Organization.
Diagnosing mental illness in children can take time because young children may have trouble understanding or expressing their feelings, and normal development varies. Your child's health care provider may change or refine a diagnosis over time.
How is mental illness in children treated?
Common treatment options for children who have mental health conditions include:
- Psychotherapy. Psychotherapy is also known as talk therapy or behavior therapy. Psychotherapy is a way to address mental health concerns by talking with a psychologist or other mental health professional. With young children, psychotherapy may include play time or games, as well as talk about what happens while playing. During psychotherapy, children and adolescents learn how to talk about thoughts and feelings, how to respond to them, and how to learn new behaviors and coping skills.
- Medication. Your child's health care provider or mental health professional may recommend a medication — such as a stimulant, antidepressant, anti-anxiety medication, antipsychotic or mood stabilizer — as part of the treatment plan. Your child's provider will explain risks, side effects and benefits of drug treatments.
How can I help my child cope with mental illness?
You will play an important role in supporting your child's treatment plan. To care for yourself and your child:
- Learn about the illness.
- Consider family counseling that treats all members as partners in the treatment plan.
- Ask your child's mental health professional for advice on how to respond to your child and handle difficult behavior.
- Enroll in parent training programs, particularly those designed for parents of children with a mental illness.
- Explore stress management techniques to help you respond calmly.
- Seek ways to relax and have fun with your child.
- Praise your child's strengths and abilities.
- Work with your child's school to secure necessary support.
