What cognitive functions are impacted by ADHD that influence verbal processing? 

ADHD affects more than attention, it also alters how the brain manages and organises spoken information. According to NICE guidance (NG87), ADHD can influence communication, learning and executive functioning, leading to difficulties holding onto and processing verbal information in real time. These challenges stem from differences in core cognitive functions that support speech, listening and comprehension. 

Executive functions and verbal processing 

Research consistently shows that working memory, attention control, inhibition and processing speed are among the most affected cognitive functions in ADHD. A 2025 study on executive function found that verbal working memory and processing speed were key shared deficits linked to both inattentive and hyperactive-impulsive symptoms. Similarly, a 2024 review of executive functioning reported strong evidence of verbal working-memory weaknesses, which can make it harder to follow or recall spoken information. 

How these functions affect speech and listening 

When working memory is reduced, it becomes more difficult to retain and integrate words into meaningful sentences. Inhibition and attention control also affect listening distractions can interrupt processing, leading to missed details or incomplete understanding. Neuroimaging studies, such as a 2025 fNIRS analysis, show reduced prefrontal activation during verbal tasks, suggesting the brain works harder to manage everyday speech and listening demands. 

Key takeaway 

ADHD influences several cognitive functions that underpin verbal processing, especially working memory, attention control and processing speed. By using written prompts, structured communication and repetition, individuals with ADHD can strengthen comprehension and reduce everyday verbal difficulties.
