Can ADHD cause individuals to forget what they’ve read shortly after? 

Many people with ADHD can read words accurately but struggle to remember what they’ve read moments later. According to NICE guidance, ADHD affects attention, working memory, and processing speed the systems needed to hold and organise information while reading. When these systems are overloaded or disrupted by distraction, information is never fully encoded, making rapid forgetting common. 

Why forgetting happens in ADHD 

Reading comprehension depends on staying focused and holding ideas in working memory as they build from sentence to sentence. Research shows that people with ADHD often lose track or drift into mind-wandering, meaning parts of the text are read without being processed. A study published in Archives of Clinical Neuropsychology found that comprehension difficulties are closely linked to working-memory limits and processing speed, even when word reading is intact (Erhan, 2014). 

Working-memory weaknesses and slower processing make it harder to retain details, while mind-wandering is more common during low-stimulation tasks. Eye-tracking studies also show that children with ADHD display more unstable fixations and greater gaze variability, which disrupts encoding (Reading Research Quarterly, 2023; Pires et al., 2025). Health information sources also note that attention lapses, not memory failure, explain the “read and forget” pattern in ADHD (Healthline). 

For assessment or structured support, private services such as ADHD Certify provide NICE-aligned ADHD assessments for adults and children in the UK. 

Key takeaway 

ADHD doesn’t usually damage memory it disrupts the attention and working-memory processes needed to store information in the first place. With structured strategies and supportive environments, many people with ADHD can improve how much they retain after reading.
