Definition

A neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning or development.

National Institute for Mental Health

In plain language

Often misunderstood as a lack of attention, people with ADHD are often challenged by a state of hyperarousal. This leads to more intense emotional reactions which can manifest as rejection sensitive dysphoria (RSD); their experiences are much more severe than that of their neurotypical peers. Kathleen Nadeau, Ph.D., author of ADD-Friendly Ways to Organize Your Life, says: "A better way to look at it is that people with ADHD have a dysregulated attention system." While individuals with ADHD are distractible, they also have a tendency to hyperfocus, which makes it difficult to "shift gears" or to stay engaged with non-preferred tasks.

Subtypes

  • Primarily hyperactive-impulsive type
  • Primarily inattentive type (formerly called ADD)
  • Combined type

In the classroom

Students with ADHD may show one or more of the following — patterns vary widely and rarely look the same in any two learners.

  • may seem to be daydreaming or staring out the window
  • may seem busy, but off-task
  • may be unable to sit still or need to constantly fidget
  • may call out impulsively without being called upon
  • may miss important details
  • may struggle with transitions from one activity to another
  • may rush through tasks and miss important steps
  • may avoid work that is not interesting or does not have clear relevance

Support strategies

  • Clear assignments: make sure assignments are clear and not too long or repetitive. Check with students to make sure they understand what they need to do.
  • Simplified instructions: keep them short, simple, and detailed. Bullet points and checklists reduce cognitive load and free mental energy for the task itself.
  • Provide choices: give students assessment options to show mastery — written essay, oral report, or hands-on project.
  • Allow breaks: frequent breaks help students focus — a drink of water, the bathroom, or a brief walk down the hallway.
  • Use visual reminders: post key concepts on brightly colored boards or highlight critical elements of written assignments.
  • Increase active participation: student-centered discussion or small-group activities.
  • Incorporate physical activity: integrate movement-based learning, such as a short workout or stretching exercises.
  • Use timers: show how much time is left in an activity or how long until a break.
  • Use checklists and schedules: include incremental due dates for larger assignments.
