Identifying teen behavior disorders, signs, types, and when to seek professional help

Estimated Reading Time: 6 minutes

Behavioral disorders in teens can include:

  • oppositional behaviors
  • impulsivity
  • aggression
  • emotional outbursts
  • defiance
  • conduct problems
  • difficulty managing emotions or social situations

I get it -- it's overwhelming trying to understand whether these behaviors are part of normal adolescence or signs of a deeper emotional, neurological, or mental health challenge. Many teens also struggle with emotional dysregulation, making school pressures, friendships, family conflict, and stress much harder to manage.

I’m Dr. Roseann Capanna-Hodge, and for over 30 years I’ve helped teens and families navigate behavioral, emotional, and neurological challenges that affect everyday functioning. I know how exhausting it can feel when conflict, emotional reactivity, or impulsive behaviors begin impacting family relationships, academics, and self-esteem.

What You’ll Learn:

  • Common signs and symptoms linked to behavioral disorders in teens.
  • The difference between typical teen behavior and clinical concerns.
  • Factors like ADHD, anxiety, trauma, and stress that may contribute to behavioral issues.

  • Conduct Disorder: Involves aggressive or antisocial behavior that violates societal norms and the rights of others.

  • Anxiety and Mood Disorders: Includes generalized anxiety, depression, and bipolar disorder.
