Is There Evidence That Overdiagnosis Worsens Mental Health? 

Yes, growing concerns suggest that ADHD overdiagnosis worsens mental health consequences are real and potentially harmful. While an accurate diagnosis can offer clarity and access to support, a mistaken label can carry unintended psychological effects. For children and adults alike, being diagnosed with ADHD when it is not warranted can increase feelings of confusion, stress, and even isolation. 

A false diagnosis may lead individuals to question their abilities or over-identify with perceived limitations. This can create a psychological burden, where people start to believe they are inherently flawed or incapable. Over time, this mindset can contribute to anxiety, depression, and reduced self-esteem, especially when treatment does not lead to meaningful improvements. 

How Overdiagnosis Can Affect Mental Health 

Here are a few ways in which ADHD overdiagnosis worsens mental health: 

Increased anxiety  

Individuals may feel pressure to meet the expectations that come with a diagnosis or fear being judged. 

Misguided treatment  

Medication or therapy aimed at managing ADHD may not help and can introduce side effects or emotional distress. 

Internalised labels  

Being told you have a disorder when it may not apply can lead to feelings of inadequacy and self-doubt. 

In conclusion, diagnosis should be empowering, not limiting. Overdiagnosis doesn’t just risk overtreatment. It can quietly erode mental health over time.
