Warning Signs of Mental Health Issues in Children

Key Takeaways

• Numerous mental disorders can emerge before the age of 12, with the most common being anxiety and attention deficit/hyperactivity disorder (ADHD).

• Sudden changes in mood, behavior, or social interactions often signal an underlying psychiatric concern that requires psychiatric support.

• Therapy is the primary treatment for children with mental health disorders, with clinical best practices recognizing the dangers of medication for this age group.

What Mental Health Looks Like in Children

Psychiatric conditions are common in children and can have lasting impacts on emotional well-being, social development, academic performance, and the family unit as a whole. According to the Centers for Disease Control and Prevention (CDC), four indicators signal stable mental health in children ages 6 months to 5 years.^[1][2]

These include:^[1][2]

• Consistently showing affection and tenderness toward caregivers.

• Demonstrating the ability to recover quickly when faced with negative emotions.

• Displaying curiosity and interest in exploring and learning new things.

• Frequently smiling, laughing, and expressing positive emotions.

For children above the age of 6, the CDC highlights three key indicators for balanced psychiatric health, including: ^[2]

• Consistently showing enquiry and enthusiasm when learning and discovering new things.

• Remaining calm and able to regulate emotions when faced with challenges or setbacks.

• Demonstrating persistence by working toward completing tasks once begun.

In light of this, the absence of one or more of these indicators in either age group could signify an underlying mental health concern. Even subtle departures from these patterns warrant consultation with a mental health professional, as timely support can prevent progression into chronic conditions.^[1]

Just a Phase?

Mental health disorders can emerge in early childhood, with their prevalence typically increasing as children grow and develop. Although some children may experience temporary emotional challenges, if a child exhibits a drastic shift in temperament or behavior, seeking support is essential to rule out the possibility of a diagnosable disorder remaining untreated.^[2]

What Is a “Problem Child”?

The label “problem child” is often applied to children who persistently display questionable behaviors such as stealing, defiance, aggression, lying, tantrums, bullying, substance abuse, self-harm, truancy, declining grades, extreme mood swings, or running away from home.^[6]

These behaviors are commonly rooted in trauma, challenging home or school environments, underlying mental disorders, and typically point towards a need for support and intervention rather than punishment, although in most cases, consequences are appropriate.^[6]

Common Disorders Found in Children

A 2022 review investigating a total of 61,000 participants aged between four and eighteen identified the following mental health disorders as the most common within the age category:^[3][7]

• Anxiety disorders: Around 5 in every 100 children are affected by excessive worry, fear, or nervousness that interferes with daily life.

• Attention-deficit/hyperactivity disorder (ADHD):  Nearly 4% of children live with ADHD, which presents with symptoms of inattention, hyperactivity, or both.

• Oppositional defiant disorder (ODD): Approximately 3 out of 100 children develop ODD (a condition involving frequent argumentative behavior, temper tantrums, and defiance directed at authority figures).

• Conduct disorder: Just over 1% of children present with conduct disorder (with symptoms of aggressive, destructive, or rule-breaking behaviors).

• Depressive disorders: Around 1 in 100 children are diagnosed with depression, which is characterized by persistent sadness, loss of interest, and changes in behavior.

Signs of Mental Health Issues in Children

While dangerous warning signs of psychiatric instability are easy to identify (such as thoughts of suicide or behaviors including self-harm or substance abuse), some subtler signs can indicate the presence of an underlying mental health condition.^[8]

These include:

• Persistent low or irritable mood (eg, crying spells or a frustrated attitude).

• Excessive anxiety or fear without a clear reason (this can look like reluctance toward specific activities, such as attending school or going to sleep).

• Reduced sense of enjoyment or interest in activities previously enjoyed.

• Social withdrawal (avoiding friends, family, or group interactions).

• Dramatic and sudden shifts in mood, personality, or behavior.

• Frequent outbursts (repeated tantrums, defiance, or aggressive behavior).

• Challenges with concentration or hyperactive, restless behavior.

• Regressive behaviors (eg, thumb-sucking or wetting the bed).

• Sleep difficulties (including trouble falling or staying asleep, oversleeping, or recurring nightmares).

• Drastic shifts in appetite and noticeable weight loss or gain.

• Physical complaints (such as recurring stomachaches or headaches without a medical cause).

• Academic struggles.

Surface vs. Concealed Symptoms

It is important to keep in mind that the symptoms listed above do not capture the full extent of a child’s mental or emotional struggles. This is due to the fact that visible behaviors (such as physical aggression or verbal defiance) are easier to identify than internal struggles. For children with emotional symptoms, these overwhelming experiences may be too difficult to communicate and can easily go unnoticed.^[2]

Discussing Mental Health With a Child

Speaking to a child about a topic as delicate and complex as mental health requires a well-timed moment, gentleness, and reassurance. The tips below outline the recommended approach to discussing psychiatric well-being with a child:

• Choose the right moment: Time the discussion after a lighthearted moment, such as after a snack, joke, or show, rather than when emotions are high or early in the morning.

• Begin by expressing your love: Let your child know that you adore them and affirm them for a few specific qualities before beginning the conversation.

• Listen more than you speak: Expect to say only half of what you would like to, so that your child can process the information gradually and feel truly heard.

• Manage your reactions: Be mindful of impatient body language and critical comments, and pause or take a deep breath to maintain an aura of calm before responding.

• Collaborate with your child: Ask your child how they would like you to respond (some may wish to vent, while others may seek guidance).

• Reassure and support: Assure your child that there is nothing inherently wrong with them, that mental health is a part of being human, and that you are always available to help.

While these tips may benefit conversations with younger children, teens and young adults often require a different approach. Our guide to helping teens and young adults with mental health may help when preparing for such conversations.

Navigating Reluctance

In cases where a child with a mental health condition is apprehensive about seeking help, you should gently ask about their concerns. During the conversation, focus on truly listening to their feelings and anxieties regarding mental health support.

Encourage your child to share their thoughts and emotions freely, and acknowledge their fears or hesitations. Make sure to show understanding of their perspective and validate what they are feeling before offering accurate information that may alleviate specific concerns.

What to Do If You Suspect Your Child Has a Mental Health Issue

If you suspect your child is experiencing a mental health challenge, it is imperative to seek a professional diagnosis to prevent any underlying issues from progressing into a lifelong disorder. Depending on the specific concerns of each child, this generally involves filling out a questionnaire about their behavioral and emotional patterns.

Getting a Diagnosis

To establish a mental health diagnosis for a minor, professionals typically recommend clinical interviews with the child, caregivers, and teachers to evaluate symptoms in different areas of the child’s life. For a specific disorder to be diagnosed, these symptoms must meet the required criteria for duration, age of onset, and not be better explained by a medical condition.^[8]

Tests and Assessments

There is a wide range of tests and assessments designed to evaluate various psychiatric disorders. Among the most widely recognized are:

• SCARED (Screen for Child Anxiety Related Emotional Disorders): A 41-item questionnaire for individuals between the ages of 8 and 18. This screening tool is completed by caregivers, teachers, or the child, and assesses anxiety across five areas.

• Vanderbilt ADHD Diagnostic Rating Scale: This 55-question assessment is filled out by a caregiver to evaluate the potential presence of ADHD  in children aged 5 to 12 years, along with frequently associated conditions.

• CBCL (Child Behavior Checklist): This checklist is completed by caregivers and is designed to identify behavioral and emotional issues associated with oppositional defiance disorder in minors aged 6 to 18, alongside teacher and self-report forms.

• Disruptive Behavior Disorders (DBD) Rating Scale: This rating scale can be used to diagnose either conduct disorder or oppositional defiant disorder in individuals aged 5 to 14, and consists of 45 questions to be completed by a teacher or caregiver.

• CDI-2 (The Children’s Depression Inventory 2nd Edition): The children’s depression inventory is a 28-item self-report questionnaire that evaluates depressive symptoms in minors aged 7 to 17 years.

Children’s Mental Health Counseling and Treatment

Therapy is considered the gold standard treatment for psychiatric disorders in both adults and children. While medications are prescribed to help treat mental health conditions in children, it is important to note that severe adverse drug reactions are responsible for nearly 4% of pediatric hospitalizations.^[4][5]

Prescribed medications are almost exclusively used as part of a treatment program that revolves around therapy and counseling. According to a 2025 review, the following therapeutic modalities have shown effectiveness in treating various common mental disorders in children:^[5]

• Play therapy.

• Cognitive behavioural therapy (CBT).

• Acceptance and commitment therapy (ACT).

• Psychodynamic therapy.

• Psychoanalytic therapy.

• Person-centred therapy.

• Systemic therapy.

• Family therapy.

• Schema therapy.

Helping Your Child Cope With Their Mental Health

Caregivers play a crucial role in supporting a child’s management of mental health. While it may seem counterintuitive to focus on yourself first, one of the most powerful ways to help your child cope with psychiatric difficulties is through modeling a healthy lifestyle.

This includes emotional regulation techniques, which can become learned behavior if you openly practice mindfulness techniques when experiencing overwhelm yourself. It is also beneficial to teach skills such as breathwork or meditation to your child when they are dysregulated.

Over and above this, it is essential to:

• Educate yourself about your child’s condition.

• Build routines that are predictable and consistent.

• Encourage balanced meals, sufficient sleep, and daily movement.

• Stay involved in their activities, interests, and friendships.

• Listen to and validate their feelings, even when seemingly irrational.

• Support coping skills by teaching emotional vocabulary and identification.

• Encourage resilience by regularly developing their sense of self-worth.

• Work with the school to support your child.

Final Thoughts

Children experiencing mental health challenges are typically unequipped to articulate their distress, and the identification of early warning signs involves careful observation of both visible and unspoken emotional struggles. By recognizing an issue before it fully develops, it is possible to support the healthy development of your child's mental and emotional equilibrium and prevent long-term difficulties.
