6 Common Behavioral Disorders in Children and Teens

What Are Behavioral Disorders?

Behavioral disorders are mental health conditions that impact the way a child behaves, processes emotions, and interacts with others. Children with behavioral disorders often struggle with rule-following, impulse control, attention, and emotional regulation. These challenges can significantly impact school performance, relationships, and home life.

There are many types of behavioral disorders, and early diagnosis is key to providing children the care and support they need. The causes of behavioral disorders in children can range from genetics and environmental stressors to chemical imbalances or even exposure to heavy metals, which research has linked to increased behavioral issues.

Common Behavioral Disorders in Children

Here is a behavioral disorders list focused on six of the most commonly diagnosed behavioral and emotional challenges seen in youth:

1. Attention-Deficit/Hyperactivity Disorder (ADHD)

ADHD is one of the most common behavioral disorders in children. It affects attention span, impulse control, and activity levels.

Symptoms of ADHD:

• Inattention (difficulty focusing, forgetfulness)
• Hyperactivity (restlessness, constant movement)
• Impulsivity (blurting out, interrupting others)

Students with emotional and behavioral disorders like ADHD may struggle in traditional classrooms without adequate accommodations. Support for at-risk youth can help guide families toward appropriate interventions.

2. Oppositional Defiant Disorder (ODD)

ODD is marked by frequent and persistent patterns of anger, irritability, defiance, and vindictiveness toward authority figures.

Symptoms of ODD:

• Frequent temper tantrums
• Argumentative behavior
• Engaging in behaviors intended to provoke others
• Refusal to follow rules

If your child frequently challenges rules at home or in the classroom, they may benefit from wraparound support. Explore wraparound services for behavioral issues.

3. Conduct Disorder (CD)

Conduct Disorder involves more severe behavior issues that may include aggression, destruction of property, or serious rule violations.

Symptoms of CD:

• Aggressive behavior toward people or animals
• Lying, stealing, or vandalism
• Truancy or running away from home

Early intervention is critical, especially when behavioral problems escalate. Children with CD often require multi-layered care, including counseling and specialized education services.

4. Anxiety Disorders

While often thought of as emotional, anxiety disorders can also lead to behavioral challenges in children. Anxiety may manifest in avoidant behaviors, outbursts, or school refusal.

Symptoms of anxiety disorders:

• Excessive worry or fear
• Refusal to go to school
• Physical complaints (headaches, stomachaches)
• Withdrawal from social situations

5. Autism Spectrum Disorder (ASD)

Autism is a developmental disability that often includes behavioral challenges such as repetitive behaviors, difficulty with transitions, or meltdowns in overstimulating environments.

Symptoms of ASD-related behavioral issues:

• Resistance to change in routines
• Difficulty with social interaction
• Intense focus on specific interests
• Repetitive movements or behaviors

Many children with autism benefit from behavior management support. Visit our page on managing behavioral challenges in children with developmental disabilities.

6. Depression

Depression in children and teens doesn’t always look like sadness. It can show up as irritability, isolation, or behavioral outbursts.

Symptoms of depression in youth:

• Changes in appetite or sleep
• Loss of interest in activities
• Low energy and motivation
• Angry outbursts or sensitivity to rejection

Early signs of depression are often overlooked. If your child seems withdrawn or unusually angry, don’t wait to seek support. Cognitive Behavioral Therapy (CBT) is a proven intervention. Explore CBT services for children and teens.

Emotional and Behavioral Disorders in the Classroom

Students with emotional and behavioral disorders in the classroom often need individualized plans and consistent support. These challenges can interfere with academic achievement, peer relationships, and classroom safety.

Teachers and caregivers can work with school-based teams to identify symptoms of behavioral disorders and tailor interventions through IEPs or 504 plans. For parents wondering how to help when their child is struggling in school, NJCMO offers guidance and support.

What Causes Behavioral Disorders?

While every child is different, some common causes and risk factors include:

• Genetic predisposition
• Prenatal exposure to drugs or alcohol
• Exposure to heavy metals (such as lead)
• Family instability or trauma
• Learning disabilities

Environmental and developmental factors often intersect with mental health, making it vital to take a holistic approach. NJCMO is here to help families identify the root causes and access resources for healing and growth.

When to Seek Help

If your child displays persistent behavioral challenges that interfere with daily life or school functioning, it may be time to seek professional help. Behavioral disorders are not a reflection of poor parenting or a child “acting out” — they are treatable mental health conditions.

NJCMO can connect you with mental health professionals, school support systems, and in-home services designed to meet your child’s specific needs.
