The teacher has mentioned it. You've noticed it at home. Homework that should take twenty minutes takes two hours. Reading that used to happen naturally now has to be forced. Your child switches tasks constantly, can't seem to settle to anything, and the moment a device is nearby, everything else stops existing.
And you're sitting with a question you're almost afraid to ask out loud: is this ADHD? Or is it the phone?
It's one of the most common questions parents are bringing to GPs, schools, and child development specialists in 2026. And the honest answer is more nuanced, and more useful, than a simple either/or.
What ADHD actually is
Attention Deficit Hyperactivity Disorder is a neurodevelopmental condition. It has a strong genetic basis. It is characterised by persistent patterns of inattention, hyperactivity, and impulsivity that are present across multiple contexts, not just at home, not just after screen time, but broadly and consistently, in ways that meaningfully affect daily functioning.
ADHD is not caused by screens. A child with ADHD would have ADHD regardless of their device use. It is a real, diagnosable condition that responds well to appropriate support, and it is significantly underdiagnosed in girls, in quieter children, and in children whose inattention doesn't come with the hyperactivity that makes the diagnosis more visible.
If you are concerned that your child may have ADHD, the right route is a referral through your GP to a paediatrician or educational psychologist. That assessment is the only reliable way to know.
What screens can do to attention
Here is the part that complicates the picture: screens can produce attention and behavioural symptoms that closely resemble ADHD, in children who don't have the condition.
A landmark study following 8,324 children (the ABCD dataset) found that social media use, not gaming or television, specifically social media, was associated with a cumulative increase in inattention symptoms over four years. The more social media use, the more inattention symptoms developed over time, even when controlling for pre-existing attention difficulties.
The mechanism is understood. Algorithmically curated content, short-form video, social feeds, games with rapid reward cycles, delivers stimulation at a rate the developing brain quickly adapts to and begins to expect. The dopaminergic reward system recalibrates around this higher baseline. Activities that don't deliver stimulation at the same pace, reading, listening, sustained homework, conversation, feel unrewarding by comparison. Not because the child is lazy or unmotivated, but because the brain has been conditioned to expect a faster rate of input and reward.
The key question to ask
The most useful question, though it won't replace a professional assessment, is this:
Do these difficulties exist across all contexts, or primarily in contexts that follow screen time or require sustained, low-stimulation engagement?
A child with ADHD struggles to sustain attention broadly and consistently, in the classroom, in conversations, during meals, in activities they genuinely enjoy as well as those they don't.
A child whose attention difficulties are primarily screen-related tends to show a specific pattern: they can sustain intense focus during high-stimulation digital activities (gaming, video watching) but struggle significantly in low-stimulation contexts, particularly after heavy screen use. Teachers often describe them as "switched off." Parents notice they used to read, used to concentrate, used to sit through a film, and somewhere, after the phone arrived, that changed.
This pattern doesn't rule out ADHD, the two can coexist. But it is a meaningful signal that screen use may be a significant contributing factor.
Why this question matters
It matters because the response is different.
If your child has ADHD, the most important thing is an appropriate assessment and support plan, which might include educational accommodations, therapy, medication, or a combination. Reducing screen time alone will not address the underlying condition, though it may reduce some symptom severity.
If your child's attention difficulties are significantly screen-related, the most important intervention is rebuilding the attention capacity that screen use has eroded, through deliberate practice of sustained, low-stimulation focus, alongside reduced exposure to high-stimulation content.
In many cases, the answer involves both. And in both cases, building attention as a skill, rather than just managing screen time, is part of the picture.
What rebuilding attention actually looks like
Attention is not fixed. It's a skill, and like all skills, it can be eroded by misuse and rebuilt through practice. The brain conditioned to expect rapid stimulation can be reconditioned. It takes time, consistency, and a degree of discomfort.
- Protect boredom deliberately. A child who can tolerate being unstimulated is building the single most important attention skill there is. Boredom is not a problem to solve, it's a practice environment.
- Daily screen-free reading. Even fifteen minutes, consistently, builds different neural pathways than passive viewing. The practice of sustaining attention on text is the point.
- One thing at a time. Multitasking, homework with a screen nearby, trains divided attention. Single-tasking, however briefly, trains sustained focus.
- Short, defined work blocks. "Read for fifteen minutes" is easier to complete than "read for a while." The Pomodoro method, short focused bursts with brief breaks, works particularly well for children recalibrating their attention span.
- Observe the pattern. What does your child's focus look like on a screen-free day versus a heavy screen day? For many families, this observation alone clarifies whether screens are a significant factor.
What to do if you're still concerned
If you've reduced screen time, built in low-stimulation practice, and the attention difficulties persist broadly and consistently, speak to your GP. Request a referral for a developmental assessment. Advocate clearly for what you're seeing.
ADHD is real. It is also underidentified in certain children. Getting the right diagnosis and support is not overreacting, it is exactly what that assessment is for.
And if the assessment doesn't indicate ADHD, the work of building attention as a skill is still the right response to screen-related attention difficulties. The two paths are not in conflict.

Frequently asked questions
Can screens cause ADHD-like symptoms?
Yes. Research consistently shows that intensive use of algorithmically driven content can produce inattention, impulsivity, and hyperactivity symptoms in children without ADHD. The brain adapts to high-stimulation content and finds slower-paced tasks harder to sustain.
How do I know if my child has ADHD or if it's screens?
The key question is whether difficulties exist broadly and consistently across all contexts, or primarily after screen use and in low-stimulation settings. ADHD affects attention across situations; screen-related attention issues tend to show a more specific pattern. Only a professional assessment can diagnose ADHD, so speak to your GP if concerned.
My child's teacher says they can't concentrate. Could this be screens?
Possibly. Teachers increasingly note a correlation between children's device use and in-class attention. If difficulties are more pronounced after weekends or school holidays (higher screen time periods), that's a meaningful signal worth raising with the school and your GP.
Can reducing screen time improve ADHD symptoms?
Research suggests reducing screen time can reduce the severity of attention symptoms, including in children with diagnosed ADHD. It is not a treatment for the condition, but may reduce the additional burden heavy screen use places on an already stretched attention system.
How long does it take to rebuild attention after reducing screens?
Research suggests measurable improvement in sustained attention within four to eight weeks of significantly reduced high-stimulation screen use, combined with deliberate low-stimulation practice. Results vary by age, baseline use, and consistency of approach.
