The difference between sensory processing issues and ADHD

ByPeg Rosen

Constantly fidgeting and squirming. Invading personal space. Melting down in public. These can be signs of both ADHD and sensory processing issues. While they’re different issues, they have some overlap and can occur together. This table breaks down some of the key differences between ADHD and sensory processing issues.

 ADHDSensory processing issues
What is it?

A neurodevelopmental condition that makes it hard for many children to concentrate and sit still.

An over- or undersensitivity to sensory input such as sights, sounds, flavors, smells and textures.

Signs you may notice
  • Seems daydreamy or confused
  • Appears not to listen
  • Is prone to tantrums and meltdowns due to lack of impulse control
  • Struggles with organization and completing tasks
  • Gets easily bored unless an activity is very enjoyable
  • Has trouble following directions
  • Struggles to sit still during quiet activities
  • Is impatient and has trouble taking turns
  • Is constantly moving
  • Fidgets and needs to pick up and fiddle with everything
  • Interrupts people and blurts things out inappropriately
  • Doesn’t understand the consequences of actions
  • Plays roughly and takes physical risks

Oversensitivity:

  • Has trouble focusing; can’t filter out distractions
  • Dislikes being touched
  • Notices sounds and smells that others don’t
  • Has meltdowns, runs off, or becomes upset in noisy, crowded places
  • Worries about safety even when there’s no real danger
  • Has difficulty with new routines, new places and other change
  • Shifts and moves around, can’t get comfortable
  • Is very sensitive to the way clothing feels

Undersensitivity:

  • Constantly needs to touch people or things
  • Has trouble gauging others’ personal space
  • Seem clumsy or uncoordinated
  • Shows a high tolerance for pain
  • Plays roughly and takes physical risks
Possible emotional and social impact

Trouble following social rules can make it hard to make and keep friends. Frequent negative feedback for acting out or not paying attention can impact self-esteem and motivation, making kids feel they’re “bad” or “no good.”

Feeling anxious in or avoiding crowded and noisy places can make it hard to socialize. Peers may avoid or exclude an undersensitive child who plays too roughly or doesn’t respect their personal space.

Professionals who can help
  • Pediatricians, developmental-behavioral pediatricians, nurse practitioners, child psychiatrists: Diagnose ADHD and prescribe ADHD medication. Psychiatrists will look for other issues like anxiety.
  • Clinical child psychologists: Provide behavior therapy to teach kids skills to manage their actions and interactions. Provide cognitive behavioral therapy to help with emotional issues related to their ADHD. Diagnose ADHD and mental health issues that may co-occur, such as anxiety. May also evaluate for learning differences.
  • Pediatric neuropsychologists: Diagnose ADHD and common mental health issues that may co-occur, such as anxiety. May also evaluate for learning differences.

  • Sensory breaks
  • Physical activity to help regulate emotions, behavior and need for movement
  • Noise-canceling headphones or ear buds to reduce stimulation in busy places like assemblies
