Can Psychotic Disorders Be Mistaken for ADHD? 

PostedSeptember 10, 2025

ByMy Patient Advice

It’s possible for psychotic disorders vs ADHD to be confused due to overlapping symptoms such as concentration issues, irritability, and impulsivity. However, the key differences between these conditions lie in the nature of the symptoms and their underlying causes. While ADHD is a neurodevelopmental disorder focused on attention and impulse control, psychotic disorders involve more severe disturbances in thinking, perception, and reality. 

In psychotic disorders vs ADHD, symptoms like hallucinations and delusions are key indicators of psychosis, whereas ADHD primarily involves difficulties with concentration issues and self-regulation. A person with ADHD might struggle to focus, but their experiences are not typically marked by distorted perceptions of reality, which is characteristic of psychotic disorders. Hallucinations (such as hearing voices or seeing things that aren’t there) and delusions (false beliefs, like thinking others are plotting against them) are commonly present in psychosis, but not in ADHD.

Common Symptoms: Psychotic Disorders vs ADHD 

Hallucinations 

People with psychotic disorders may experience visual or auditory hallucinations, which can severely impact their perception of reality. In contrast, those with ADHD may struggle to stay focused, but they do not experience these extreme distortions. 

Delusions

 Delusions are false beliefs that can make it difficult for individuals with psychotic disorders to function in daily life. Individuals with ADHD, however, are more likely to have concentration issues without the presence of delusional thinking. 

Concentration Issues 

While both conditions can involve difficulty focusing, the concentration issues in ADHD are generally related to inattention and impulsivity, whereas in psychotic disorders, the focus is often impaired due to disturbed thoughts or perceptions. 

By recognising the difference between psychotic disorders vs ADHD, clinicians can ensure that patients receive the appropriate treatment for their condition.
