Can Inattentive ADHD Be Misdiagnosed as Anxiety or Depression?

Yes, inattentive ADHD is commonly misdiagnosed as anxiety or depression, particularly in adults. The overlap in symptoms, such as trouble focusing, low motivation and chronic overwhelm, can easily blur diagnostic lines. Without a full clinical assessment, individuals may be offered the wrong ADHD treatment, which leads to ongoing frustration.

This confusion often affects parents too, as they try to support children whose symptoms are mistaken for emotional or behavioural issues. For anyone navigating parenting ADHD, recognising the difference between conditions is key to getting the right ADHD diagnosis and long-term support.

How Symptoms Overlap but Differ

Although symptoms may look similar, ADHD, anxiety and depression have distinct underlying causes. Understanding these differences helps ensure accurate diagnosis and effective treatment:

Time management problems

People with ADHD often struggle with time management, finding it hard to start, plan or complete tasks on schedule due to executive function challenges. In contrast, anxiety may cause task paralysis, and depression can bring motivational loss.

Emotional presentation

Anxiety is driven by worry, and depression by sadness or flatness. ADHD may involve frustration, restlessness or emotional reactivity, especially in children where parenting ADHD requires tailored responses.

Response to treatment

ADHD typically responds well to CBT, routine-building and medication. If traditional anxiety or depression treatments are not helping, a missed ADHD diagnosis might be the cause.
