Signs of ADHD in Teens

Attention Deficit Hyperactivity Disorder (ADHD) is a medical condition that affects brain function and development, resulting in difficulties with attention, impulsivity, and self-regulation. The signs of ADHD in teens are classified into two categories: signs of inattention and signs of hyperactivity and impulsivity.

Signs of Inattention

• Difficulty paying attention to details, making careless mistakes in schoolwork
• Lack of focus during activities or conversations
• Inability to follow instructions fully, requiring frequent reminders
• Disorganization and poor time management, resulting in missed deadlines and disordered belongings
• Frequent loss or misplacement of items
• Difficulty remembering chores, tasks, and appointments

Signs of Hyperactivity and Impulsivity

• Feeling restless and constantly moving around
• Fidgeting and squirming while seated
• Inability to stay seated or engage in quiet activities
• Excessive talking and interrupting others
• Inability to wait for turns or stand in line
• Intrusive behavior in conversations, activities, or games

Childhood vs Teenage ADHD Symptoms

ADHD symptoms may change as a child grows older. Hyperactivity and impulsivity often decrease, while inattention becomes more prominent in teenagers due to increased academic demands. Teenagers with ADHD may engage in risky behaviors like unsafe sexual activity and substance abuse.

Diagnostic Criteria for ADHD in Teens

Healthcare providers use the criteria listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose ADHD:

• Six or more symptoms of inattention and/or hyperactivity and impulsivity, present for over six months
• Symptoms present before the age of 12
• Symptoms occur in two or more settings
• Symptoms interfere with daily functioning and affect academic performance, relationships, and quality of life
• Symptoms are not due to another mental health condition

Subtypes of ADHD

• Predominantly Inattentive ADHD: Meets criteria for inattention but not hyperactivity and impulsivity
• Predominantly Hyperactive-Impulsive ADHD: Meets criteria for hyperactivity and impulsivity but not inattention
• Combined Type ADHD: Meets criteria for both inattention and hyperactivity and impulsivity

Complications

Teenagers with ADHD may also have other mental health conditions such as anxiety, depression, or conduct disorder. These conditions can be treated alongside ADHD.

A Word From Verywell

ADHD can significantly impact a teenager's life, affecting their schoolwork, relationships, and overall well-being. Recognizing the signs of ADHD and seeking treatment can help reduce symptoms and improve their quality of life.
