Did you know? Studies show that the brain continues to mature well into the 20s.

Mental health conditions and disorders don't only affect adults. Children and teens can experience mental health problems too. In fact, research has now shown that most mental disorders follow a developmental course that typically starts early in life. This is true not only of conditions such as autism and ADHD, which are well known for having onset in childhood, but also for mood, anxiety, and psychotic disorders. So, many people who suffer from depression, social phobia, obsessive compulsive disorder, bipolar disorder, or schizophrenia showed signs before they were 24 years old.

Like adults, children and teens can sometimes experience intense emotions as they get older or go through stressful or traumatic events in their lives. For example, it is common for children to feel anxious about school or friendships, or for teens to have short periods of depression after a death in the family.

Mental disorders are different. They can cause ongoing, severe symptoms that affect how a child feels, thinks, acts, and handles daily activities, such as going to school, sleeping, or eating. It is important to know the signs and seek help if needed.

Warning Signs

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 signs and symptoms that last weeks or months; and if these issues interfere with the child’s daily life, not only at home but at school and with friends, you should contact a health professional.

Your child or teen might need help if he or she:

  • Often feels anxious or worried
  • Has very frequent tantrums or is intensely irritable much of the time
  • Has frequent stomachaches or headaches with no physical explanation
  • Is in constant motion, can’t sit quietly for any length of time
  • Has trouble sleeping, including frequent nightmares
  • Loses interest in things he or she used to enjoy
  • Avoids spending time with friends
  • Has trouble doing well in school, or grades decline
  • Fears gaining weight; exercises, diets obsessively
  • Has low or no energy
  • Has spells of intense, inexhaustible activity
  • Harms herself/himself, such as cutting or burning her/his skin
  • Engages in risky, destructive behavior
  • Harms self or others
  • Smokes, drinks, or uses drugs
  • Has thoughts of suicide
  • Thinks his or her mind is controlled or out of control, hears voices

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, visit . 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
  • The Crisis Text Line: 741741
  • The National Suicide Prevention Lifeline: 1-800-273-TALK (8255).

If you or your child is thinking about harming yourself get help immediately . You can call 911 or the National Suicide Prevention Line  at 1.800.273.TALK (8255).

Clinical Trials

Children are not little adults, yet they are often given medicines and treatments that were only tested in adults. There is a lot of evidence that children’s developing brains and bodies can respond to medicines and treatments differently than how adults respond. The way to get the best treatments for children is through research designed specifically for them.

Should your child participate in a clinical study?

Parents and caregivers may have many questions when they are considering enrolling a child in a clinical study, and that children and adolescents also want to know what they will go through. NIMH is committed to ensuring that families trying to decide whether to enroll their child in a clinical study get all the information they need to feel comfortable and make informed decisions. The safety of children remains the utmost priority for all NIMH and NIH research studies.
