Why they're so easy to confuse
Both ADHD and anxiety can cause a child to seem distracted, unfocused, resistant to tasks, and emotionally reactive. A teacher might describe a child with either condition in nearly identical terms: "can't sit still," "gets upset easily," "avoids challenging work," "seems to be somewhere else." Getting the distinction right matters enormously — because the treatment approaches are different, and what helps one can make the other worse.
The key question
With ADHD, the problem is in the engine — attention regulation, impulse control, and executive function are genuinely harder to operate. The child isn't avoiding tasks because they're worried about failing; they're struggling to engage because their brain doesn't sustain attention easily.
With anxiety, the problem is in the brake system — the child is so focused on potential threat that their brain can't engage with the task at hand. They may actually have strong executive function; it's just being hijacked by worry.
Ask: when a child avoids a task, is it because they can't get started — or because they're afraid of what will happen if they try?
Signs that point to ADHD
- Inattention is consistent across settings — not just in high-stakes situations
- The child can focus intensely on things they enjoy (hyperfocus)
- Impulsivity: acting before thinking, difficulty waiting, interrupting
- Disorganization: loses things, forgets steps, trouble managing time
- Symptoms have been present since early childhood
Signs that point to anxiety
- Inattention is situational — worse in high-pressure or evaluative contexts
- Lots of reassurance-seeking ("Is this right?" "What if I get it wrong?")
- Physical symptoms: stomachaches, headaches before tests or events
- Perfectionism — refusing to submit work that isn't "perfect"
When it's both
ADHD and anxiety commonly co-occur — roughly 50% of children with ADHD also have significant anxiety. A thorough evaluation by a psychologist can clarify what's driving what and guide the right treatment approach.
