Can ADHD Be Misdiagnosed as Anxiety or Depression? 

Yes, ADHD can be misdiagnosed as anxiety or depression, especially in adults. The overlapping symptoms such as trouble concentrating, restlessness, or emotional overwhelm can make it difficult to distinguish between these conditions. This is why a careful differential diagnosis is essential. Without it, individuals may receive treatment for the wrong issue, leaving the core symptoms of ADHD unaddressed. 

Both anxiety and depression can mask or mimic the presentation of ADHD. For example, someone with ADHD might feel anxious because they’re constantly behind on tasks or forget important deadlines. Likewise, long-term struggles with focus and underachievement can lead to feelings of low self-worth and symptoms of depression. In these cases, ADHD is the root cause, but what gets diagnosed are the comorbid disorders that appear on the surface. 

Why ADHD Is Sometimes Misdiagnosed 

ADHD can be misdiagnosed as anxiety or depression due to the following reasons:  

Symptom Overlap  

Difficulty focusing, fatigue, irritability, and forgetfulness are common in both ADHD and mood disorders, which can blur the diagnostic picture. 

Comorbid Disorders  

Many individuals with ADHD also have anxiety or depression, making it harder to identify the primary condition without a thorough assessment. 

Missed Childhood Signs  

Especially in adults, undiagnosed ADHD may be overlooked because childhood symptoms were never formally identified, leading to a default diagnosis of anxiety or depression. 

In conclusion, to ensure accurate diagnosis, a full evaluation should include a review of childhood symptoms, behavioural patterns, and a comprehensive mental health history.
