How does ADHD impact my ability to remember what was just said?
ADHD is widely recognised as a neurodevelopmental condition that affects how the brain manages attention, focus and working memory. According to NICE guidance, ADHD involves patterns of inattention, impulsivity and hyperactivity that interfere with everyday life at school, work or home. When people describe “forgetting what was just said”, it’s usually not about memory loss in the traditional sense, but about difficulties with attention and working-memory encoding, which means the information was never fully processed in the first place.
Why does it feel like I forget things so quickly?
The everyday forgetfulness that many people with ADHD describe often begins with distractibility. If attention drifts even briefly during a conversation, the information may never be properly stored in working memory. The NHS explains that adults with ADHD often find it hard to follow instructions, stay focused or finish tasks, which can lead to misplaced items, missed steps or difficulty recalling what was said moments earlier. This isn’t a sign of poor intelligence but rather a difference in how the brain filters and processes incoming information.
Neuroscientific research shows that adults with ADHD tend to perform worse on verbal and visuospatial working-memory tasks than neurotypical adults, particularly when distractions are high or tasks are complex. Studies in Frontiers in Psychiatry and PubMed Central have linked this to reduced dopamine activity in fronto-striatal and prefrontal brain networks, which are vital for holding and updating information in real time. Too little dopamine can make it harder to maintain focus long enough for new information to “stick”.
What’s actually happening in the brain?
According to current evidence, ADHD affects the brain’s executive functions, which include attention, planning and short-term memory. When dopamine and noradrenaline levels are imbalanced, it can lead to slower processing and weaker recall. This helps explain why a person might appear not to listen when their attention or working memory simply cannot keep up with rapid speech or multitasking demands.
Key takeaway
Forgetfulness in ADHD is not about losing memories but about how attention and working memory work together. Evidence from NICE and the NHS shows that difficulties remembering what was just said stem from differences in information encoding and focus, not from memory decay. With support, structure and treatment, many people with ADHD can strengthen these skills and manage day-to-day recall more effectively.
