Why do I forget what was just said to me with ADHD?
For many people with ADHD, it can feel frustrating when words seem to “slip away” moments after hearing them. This is not a sign of laziness or disinterest, but rather a reflection of how ADHD affects attention and memory processing. According to NICE guidance, ADHD disrupts how the brain focuses, organises, and stores information, especially when distractions or emotional stress are present.
Understanding why this happens
When someone with ADHD hears information, their brain may not fully encode it before moving to the next thought or stimulus. The NHS explains that short attention span and distractibility can interrupt how information is registered in working memory. Instead of storing a complete message, the brain may capture fragments, making it difficult to recall what was said moments later.
Studies summarised in The Lancet Psychiatry and BMJ Open show that the prefrontal cortex, which manages executive functions such as attention and memory, works less efficiently in people with ADHD. When working memory capacity is exceeded, new information replaces what was just processed. This is why many adults describe moments of “blankness” or losing the thread mid-conversation, even when they are trying to listen carefully.
Working memory and attention in ADHD
As outlined in NICE NG87 and NHS Dorset’s ADHD information, forgetfulness and seeming not to listen are recognised core symptoms. These reflect a difficulty in holding short bursts of verbal information. When attention slips for even a second, the details may never reach memory, leaving gaps that feel confusing and frustrating.
Distractibility, dopamine, and executive function
Low dopamine levels influence how efficiently the brain filters distractions. Research in Clinical Psychopharmacology and Neuroscience found that adults with ADHD have greater trouble ignoring irrelevant sounds, leading to missed or incomplete recall. The Mayo Clinic notes that this often happens during multitasking or emotional stress, when working memory is overloaded.
Treatment and everyday strategies
According to NICE recommendations, stimulant medications such as methylphenidate and lisdexamfetamine can help strengthen focus and reduce forgetfulness. Psychological therapies like cognitive behavioural therapy (CBT) support people to develop practical strategies, including note-taking, summarising key points aloud, and reducing distractions during important conversations. Simple habits such as turning off background noise or confirming details verbally can significantly improve day-to-day communication.
Key takeaway
Forgetting what was just said is a common feature of ADHD caused by working memory and attention challenges, not by carelessness. With the right treatment, structure, and understanding from others, people with ADHD can manage these moments more confidently and improve how they connect and communicate.
