Language deficit with attention-deficit disorder: a prevalent comorbidity

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Speech and Language Pathology

Background:

• Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children.
• Comorbid conditions frequently present in children diagnosed with ADHD.
• The relationship between ADHD and language problems requires further investigation.

Purpose of the Study:

• To determine the prevalence of language problems in children with ADHD.
• To compare behavioral and neurocognitive patterns in children with ADHD and comorbid language problems versus those with ADHD only.
• To assess the diagnostic utility of language evaluations compared to IQ tests in this population.

Main Methods:

• A cohort of 3208 children aged 6-11 years was assessed.
• Data collection included teacher behavioral questionnaires, pediatric interviews, IQ assessments, attention tests, and language evaluations.
• Statistical analyses included correlation and group assignment prediction.

Main Results:

• 5.2% of children had primary ADHD; 45% of these also had language problems.
• Language problems were more prevalent in girls with ADHD (P = .02).
• Sequencing and short-term memory deficits were linked to attention-deficit and language problems, but attention scores were not. Language performance was a better predictor of group assignment than IQ.

Conclusions:

• A significant number of children with ADHD exhibit language comorbidities not detected by IQ tests.
• Language assessments should be integrated into routine evaluations for children with ADHD.
• Children with ADHD and language problems may have distinct underlying neurocognitive profiles compared to those with ADHD alone.
