It can be tough to tell if troubling behavior in a child is just part of growing up or a problem that should be discussed with a health professional. But if there are behavioral signs and symptoms that last weeks or months, and if these issues interfere with the child’s daily life at home and at school, or with friends, you should contact a health professional.

Young children may benefit from an evaluation and treatment if they:

• Have frequent tantrums or are intensely irritable much of the time
• Often talk about fears or worries
• Complain about frequent stomachaches or headaches with no known medical cause
• Are in constant motion and cannot sit quietly (except when they are watching videos or playing video games)
• Sleep too much or too little, have frequent nightmares, or seem sleepy during the day
• Are not interested in playing with other children or have difficulty making friends
• Struggle academically or have experienced a recent decline in grades
• Repeat actions or check things many times out of fear that something bad may happen

Older children and adolescents may benefit from an evaluation if they:

• Have lost interest in things that they used to enjoy
• Have low energy
• Sleep too much or too little, or seem sleepy throughout the day
• Spend more and more time alone, and avoid social activities with friends or family
• Diet or exercise excessively, or fear gaining weight
• Engage in self-harm behaviors (such as cutting or burning their skin)
• Smoke, drink alcohol, or use drugs
• Engage in risky or destructive behavior alone or with friends
• Have thoughts of suicide
• Have periods of highly elevated energy and activity, and require much less sleep than usual
• Say that they think someone is trying to control their mind or that they hear things that other people cannot hear

Mental illnesses can be treated. If you are a child or teen, talk to your parents, school counselor, or health care provider. If you are a parent and need help starting a conversation with your child or teen about mental health, find resources for families  from the Substance Abuse and Mental Health Services Administration. If you are unsure where to go for help, ask your pediatrician or family doctor or visit NIMH’s Help for Mental Illnesses webpage.

It may be helpful for children and teens to save several emergency numbers to their cell phones. The ability to get immediate help for themselves or for a friend can make a difference.

• The phone number for a trusted friend or relative
• The non-emergency number for the local police department
• 988 Suicide & Crisis Lifeline: 988

If you or someone you know needs immediate help, call or text the 988 Suicide & Crisis Lifeline  at 988.
