When Kids Struggle to Focus: ADHD, Anxiety, or Both?

Parents often come to us at Devonshire Pediatric Neuropsychology with a very real, very understandable question:

“My child can’t focus. Is this ADHD…or anxiety?”

The confusing part is that ADHD and anxiety can look very similar on the surface. Both can cause trouble paying attention, forgetfulness, and “zoning out” in school. But underneath, the reasons can be very different—and so are the supports that help.

What Is ADHD in Children?

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition. It affects how a child’s brain manages attention, activity level, impulse control, planning/ organization, as well as emotional and behavioral regulation. Kids with ADHD are not “lazy” or “unmotivated.” Their brains simply process information and regulate behavior differently.

Here are some common signs of ADHD and what you might notice about your child:

• Struggles to sit still

  • Fidgets, taps, or constantly moves

  • May get up from their seat when others stay seated

• Acts impulsively

  • Blurts out answers

  • Interrupts conversations

  • Acts before thinking through consequences

• Has trouble sustaining attention

  • Drifts off during instructions

  • Starts tasks but doesn’t finish

  • Gets easily distracted, even during fun activities

• Seems disorganized or forgetful

  • Loses items (homework, jackets, water bottles)

  • Forgets multi-step directions

  • Needs frequent reminders

These patterns tend to be consistent across settings (home, school, activities) and show up over time—not just during stressful periods.

What Is Anxiety in Children?

Anxiety is more about how a child’s brain responds to perceived threat, stress, or uncertainty. Some worry is normal. But when anxiety becomes intense, frequent, or interferes with daily life, it may be an anxiety disorder.

Here are some common signs of anxiety and what you might notice in your child:

• Worries a lot:

  • About school performance, friends, or safety

  • About making mistakes or disappointing others

• Avoids certain situations:

  • Doesn’t want to go to school, activities, or social events

  • Avoids starting tasks they find scary or overwhelming

• Seeks reassurance:

  • Frequently asks, “Is this okay?” “Am I in trouble?”

  • Needs repeated comfort about the same concern

• Shows physical signs of worry:

  • Stomachaches, headaches, trouble sleeping

  • Tense, restless, or clingy

• Seems “zoned out” or distracted:

  • Not because they’re bored, but because their mind is busy worrying

Anxiety can come and go with specific triggers (tests, social situations, changes in routine), and the child often feels distressed by their own worry.

ADHD and Anxiety Are Easy to Confuse because they both can lead to:

• Trouble focusing

• Forgetfulness

• Slow work completion

• Avoidance of schoolwork

• “Daydreaming” or zoning out

From the outside, these behaviors may look the same. But the underlying reasons are often different.

ADHD: The Attention System Is Struggling

With ADHD, the child might:

• Want to focus, but their attention jumps from one thing to another

• Start a task, then get distracted by something else

• Forget instructions because their brain didn’t fully register them in the first place

• Be trying very hard to control their behavior or their emotional reactions but it is hard work and then they have to deal with the consequences

The main challenge is regulation of attention and impulses.

Anxiety: The Brain Is Busy Worrying

With anxiety, the child might:

• Have trouble focusing because their mind is filled with “what if?” thoughts

• Avoid tasks because they’re afraid of failing or feeling embarrassed

• Seem inattentive, but internally they’re very focused—on their fears

The main challenge is managing worry and fear.

Key Questions to Help Differentiate ADHD and Anxiety

These questions are not a diagnosis, but they can help you start noticing patterns.

1. When Did the Difficulties Start?

• ADHD symptoms often appear early (preschool or early elementary) and are relatively stable over time.

• Anxiety may appear later or intensify with specific stressors (a big move, bullying, school transition, family stress).

2. Are Symptoms Present in Many Settings?

• ADHD usually shows up in multiple places: home, school, activities, social settings.

• Anxiety might be more situation-specific: mainly at school, only in social situations, or before tests.

3. What Seems to Drive the Inattention?

Ask yourself:

• Does my child lose focus when they are calm and not stressed? (More suggestive of ADHD.)

• Or mostly when they are worried or fearful about something? (More suggestive of anxiety.)

4. Is There a Pattern of Worry?

• Kids with ADHD may feel frustrated, discouraged, or upset—but they are not typically driven by persistent worry.

• Kids with anxiety often express lots of “what if” thoughts, perfectionism, fear of failure, or intense need for reassurance.

5. How Does My Child Feel About Their Difficulties?

• A child with ADHD might say, “I’m trying, but I just can’t focus,” or “It’s boring.”

• A child with anxiety might say, “I’m scared,” “What if I mess up?” or “What if everyone laughs at me?”

Can a Child Have Both ADHD and Anxiety?

Yes. And this is very common.

• Kids with ADHD may develop anxiety after years of struggling with school, organization, or social feedback.

• Kids with anxiety may seem inattentive because their thoughts are consumed by worry.

When both are present, it can be especially challenging to sort out what is causing the symptoms. That’s where a careful, comprehensive evaluation can make a big difference.

How a Pediatric Neuropsychological Evaluation Can Help

At Devonshire Pediatric Neuropsychology, our goal is not just to give a label—but to understand your child as a whole person.

A pediatric neuropsychological evaluation can:

• Assess attention, impulse control, and executive functions (planning, organizing, shifting between tasks)

• Evaluate learning skills, such as memory, language, reading, writing, and math

• Explore emotional and behavioral functioning, including anxiety, mood, reactivity, dysregulation, and coping skills

• Look at patterns across settings, using parent, teacher, and self-report (when age appropriate)

By bringing all of this information together, we can help answer questions such as:

• Is this primarily ADHD?

• Is this primarily anxiety?

• Are both present, and if so, how do they interact?

• What supports will help my child at home and at school?

The outcome is a clear, individualized roadmap, not only for understanding your child’s challenges, but also for using their strengths.

What Support Can Look Like

Depending on the results, support might include:

• For ADHD:

  • Classroom accommodations (movement breaks, visual schedules, chunking tasks)

  • Executive function coaching strategies

  • Occupational therapy to help build emotional/behavioral regulation skills

  • Behavior strategies at home and school

  • Consultation about medication options (when appropriate, with your prescribing provider)

• For Anxiety:

  • Cognitive-behavioral therapy (CBT) to manage worries

  • Gradual exposure to feared situations with support

  • Relaxation and coping strategies (breathing, grounding, self-talk)

  • School supports that reduce unnecessary stress and build confidence

  • Consultation about medication options (when appropriate, with your prescribing provider)

When both are present, the plan often addresses attention and anxiety together, in a coordinated way.

You don’t have to solve this puzzle on your own.

At Devonshire Pediatric Neuropsychology, we specialize in understanding how children think, feel, learn, and behave. Understanding the “why” behind your child’s struggles is the first step toward helping them feel more confident, capable, and supported—at school, at home, and beyond.
