One of the most common conversations I have with parents goes something like this: their child has been struggling at school, their teacher has mentioned ADHD, but something about that label doesn't quite fit for them. Or the opposite - a child who's been anxious for years gets an ADHD evaluation, and suddenly a lot of things make sense that didn't before.
ADHD and anxiety are two of the most common mental health concerns in children and teenagers. They're also two of the most commonly confused with each other, and for good reason. On the surface, they can look nearly identical. A child who can't focus in class might be distracted because their brain is wired differently, or because they're consumed by worry. A child who avoids homework might be avoiding it because they can't sustain attention, or because the fear of doing it wrong is paralyzing. From the outside, the behavior looks the same. What's driving it is completely different.
This matters because what helps is different too.
ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition, which means it's a difference in how the brain is wired rather than a response to circumstances. It shows up in three main presentations: primarily inattentive, primarily hyperactive-impulsive, or combined.
The hyperactive-impulsive presentation is the one most people picture - the kid who can't sit still, blurts out answers, acts before thinking, and seems to be running on a different speed than everyone else. This presentation tends to get identified earlier because it's harder to miss.
The inattentive presentation is subtler and more commonly missed, especially in girls. This is the child who seems to be daydreaming constantly, who loses track of assignments and belongings, who starts tasks and drifts before finishing them, who's described by teachers as "spacey" or "somewhere else." The inattentive child is often not disruptive - they're just not fully there.
Some specific things that tend to point toward ADHD rather than anxiety:
The difficulty is consistent across contexts. An ADHD child struggles to focus in class, at home during homework, and during activities they actually enjoy - though they may be able to hyperfocus on things that are highly engaging. Anxiety tends to be more situational: a child who focuses fine at home but falls apart in testing situations is more likely dealing with anxiety.
There's a quality of impulsivity that isn't about avoidance. ADHD impulsivity is about acting before thinking, not about getting out of something scary. The child who calls out answers without raising their hand, who can't wait their turn in a game, who grabs something before asking - that pattern points more toward ADHD.
The distractibility is external as well as internal. ADHD brains get pulled toward external stimuli - the sound across the room, the movement out the window, whatever is most interesting in the environment. Anxious children are usually distracted by internal stimuli - their own thoughts, worries, and what-ifs.
Anxiety is a broad category that covers a lot of different presentations in children. Some kids are visibly anxious - they worry out loud, seek reassurance constantly, cry before school, or express fears directly. But many anxious children don't look anxious in the way adults expect.
An anxious child who can't sit still in class might look hyperactive. An anxious child who avoids tasks they're afraid to fail at might look oppositional or unmotivated. An anxious child who is so consumed by worry that they can't concentrate might look like they have attention problems.
Some specific things that tend to point toward anxiety rather than ADHD:
The difficulty is situational. If a child can focus beautifully on some things and completely falls apart on others - particularly things that involve evaluation, social exposure, or unpredictability - anxiety is more likely than ADHD. A child who reads for hours at home but can't sustain attention in class is worth looking at through an anxiety lens.
There's avoidance of specific things. ADHD avoidance tends to be about tasks that are boring or effortful. Anxiety avoidance tends to be about things that are scary - raising your hand in class, taking a test, going to a birthday party where you don't know many people, trying something new. The "why" of the avoidance is different.
Physical symptoms show up. Anxiety in children often has a somatic component - stomachaches, headaches, nausea, and other physical complaints that appear before anxiety-provoking situations and disappear once those situations pass. ADHD doesn't typically produce physical symptoms in this way.
Reassurance-seeking is a consistent pattern. An anxious child needs to check and re-check. "Is the homework right?" "What if I get it wrong?" "Are you sure we'll be there on time?" That repetitive reassurance-seeking is an anxiety behavior, not an ADHD one.
Here's where it gets complicated: research suggests that up to 30-50% of children with ADHD also have a clinically significant anxiety disorder. The two conditions overlap frequently, and each can make the other look worse.
ADHD makes anxiety more likely, partly because the experience of repeatedly struggling - academically, socially, with organization - creates real reasons to feel anxious. A child who has been forgetting assignments and falling behind for years often develops genuine anxiety about school performance, not because they were wired to be anxious, but because the ADHD has created a track record of difficulty that now feels threatening.
Conversely, anxiety can make ADHD look worse. The mental load of managing worry takes up working memory and cognitive bandwidth that would otherwise be available for focusing and task completion. An anxious child with ADHD is dealing with two things at once, and the combination is harder than either alone.
What this means practically is that sometimes the right answer isn't ADHD or anxiety. It's both, evaluated and treated with both in mind.
This is the part that matters most, because the most effective approaches for ADHD and anxiety are meaningfully different.
For ADHD, the evidence points strongly toward a combination of behavioral strategies, environmental accommodations, skills training (often through CBT approaches adapted for ADHD), and in many cases medication. Structure, external systems, breaking tasks into smaller pieces, and building routines that don't rely on the brain to generate its own organization - these are the kinds of things that move the needle.
For anxiety, the gold standard is Cognitive Behavioral Therapy. The core of CBT for anxiety involves learning to recognize anxious thought patterns, understanding the anxiety response, and gradually facing feared situations in a supported way rather than avoiding them. Avoidance is the thing that keeps anxiety alive, and therapy works by interrupting that cycle in a structured, manageable way.
When both are present, treatment needs to account for both. Treating only the ADHD without addressing the anxiety that's developed around it often produces incomplete results. Treating only the anxiety without addressing the underlying ADHD means the child is still struggling with attention and impulsivity in ways that will continue to create new anxiety.
First, don't rely on a single source of information. Teacher reports are valuable - teachers see your child in an environment you don't, and their observations matter. But a teacher saying "I think your child might have ADHD" is an observation, not a diagnosis, and a referral to a mental health professional or a pediatric psychologist for proper evaluation is the appropriate next step.
Second, pay attention to the contexts in which your child struggles. Keep some informal notes over a few weeks about when the difficulty shows up, what precedes it, what it looks like, and what tends to help. That information is genuinely useful in an evaluation.
Third, consider starting with a consultation with a therapist who works specifically with children and adolescents. A clinical interview - with you, with your child, and drawing on teacher feedback - can often get you much further than waiting months for a formal evaluation and can help you understand what you're looking at well enough to decide on next steps.
Los Angeles has a range of evaluation resources, from pediatric neuropsychologists who do comprehensive testing to child therapists who can do a solid clinical assessment and refer on if formal testing seems warranted. You don't necessarily have to start at the most intensive and expensive option.
If you're in the LA area and navigating this question about your child, I'm glad to help you think through it. A consultation call is a low-pressure way to share what you're observing and get a clinical perspective on where to go from here.
