Many people with ADHD find that reading can feel like hard work, especially when trying to remember or make sense of what they’ve just read. According to NICE guidance (NG87), ADHD can affect concentration, working memory and processing speed, all key skills needed to understand written material. Even when decoding words is easy, holding ideas in mind and linking them together can be more difficult.
Why reading comprehension can be harder in ADHD
Research suggests that people with ADHD often have weaker executive functions, such as working memory and sustained attention, which support reading comprehension. A 2024 neuroimaging study found that limited working-memory activity in ADHD reduces deeper understanding of text. Similarly, a 2023 study of university students reported that differences in comprehension were strongly linked to executive-function measures like attention, planning and inhibition.
Supporting better reading focus
Educational and clinical guidance highlight the value of structure and visual support. The NHS ADHD booklet for adults recommends breaking reading into smaller sections, using summaries, and allowing extra time. NICE also advises using written and visual aids to help people with ADHD manage complex information and tasks.
Key takeaway
Reading comprehension challenges in ADHD are not about intelligence or effort. They stem from how the brain manages attention and working memory. With practical strategies, environmental support and professional guidance, people with ADHD can strengthen comprehension and enjoy reading with greater confidence.
