Why do I suddenly forget what someone just said with ADHD? 

Sometimes, a person reaches the end of a sentence only to realise they have forgotten the beginning. For people with ADHD, this is a common experience. ADHD forgetfulness is often linked to challenges with short-term memory and attention regulation, particularly in fast-moving or emotionally charged conversations.

In ADHD, the brain can struggle to encode and retain information in real-time. This is especially true in social settings where conversational memory is required, such as juggling what is being said, planning a response, and blocking out distractions all at once. The result is often cognitive lapses that feel sudden and disorienting, even in casual chats. 

How ADHD Disrupts Conversational Memory 

Here are some reasons memory can falter in the middle of a chat: 

Attention bottlenecks:  

Your brain might have been distracted or multitasking mentally when the person spoke, so the information was never fully stored. CBT-based strategies can help train focus on active listening and reduce mental clutter during social interactions. 

Working memory overload:  

ADHD often limits the amount of information you can mentally “hold” at one time. Using memory aids (like repeating key points or jotting quick notes) can ease the pressure. 

Processing delays:  

Sometimes your brain is still catching up on earlier parts of the conversation, causing newer details to get lost. Slowing the pace or asking for repetition without shame can help bridge those gaps.
