Attentional problems occur across multiple psychiatric disorders and are not specific for ADHD

Area of Science:

• Psychiatry
• Neuroscience
• Cognitive Psychology

Background:

• Attentional problems are frequently observed in various psychiatric conditions.
• Attention deficit hyperactivity disorder (ADHD) is often presumed to be the primary cause of sustained attention deficits.

Purpose of the Study:

• To investigate sustained attention deficits across a spectrum of psychiatric disorders using a trans-diagnostic approach.
• To determine if attention problems are specific to ADHD or prevalent in other mental health conditions.

Main Methods:

• Utilized a computerized continuous performance task (rapid visual information processing) to measure sustained attention in 576 participants (aged 18-29).
• Assessed sustained attention using sensitivity index and target detection metrics.
• Examined attentional deficit profiles across disorders using z-scores relative to a control group.

Main Results:

• Significant impairments in target sensitivity were observed in social phobia, obsessive-compulsive disorder (OCD), bulimia nervosa, and intermittent explosive disorder (effect size ≥ 0.8).
• Target detection was impaired across multiple disorders, with OCD and binge eating disorder showing the most pronounced deficits.
• Post-traumatic stress disorder (PTSD) and compulsive sexual behavior demonstrated spared performance on both attention measures.

Conclusions:

• Impaired sustained attention is not specific to ADHD; several other psychiatric disorders exhibit significant attention deficits.
• Clinicians should consider screening for a broader range of disorders when patients report attentional problems, rather than solely attributing them to ADHD.
• Further research is needed to explore the influence of comorbidities and psychoactive substances on identified attention profiles.
