For many people with ADHD, forgetfulness isn’t just an occasional lapse, it’s part of how their brain processes information. According to NICE guidance (NG87, 2025) and NHS advice, ADHD-related memory and organisational problems usually persist throughout life, though their impact can change as people learn to adapt.

Why ADHD memory issues persist

ADHD affects executive functions the brain’s internal systems for planning, prioritising, and remembering. Research published in The BMJ (2024) and PubMed (2025) confirms that working memory and attention deficits remain stable across adulthood and older age, even as people gain more life experience.

These lifelong challenges don’t mean people can’t improve rather, the way they manage forgetfulness evolves. Many adults develop structured coping mechanisms such as reminders, task lists, and external cues to compensate for their brain’s natural inconsistencies.

Adapting over time

Evidence from Frontiers in Psychology (2024) shows that adults who use ADHD coaching, CBT, or structured routines can significantly reduce the day-to-day impact of forgetfulness, even if their cognitive profile doesn’t change.

This functional improvement is often due to compensatory strategies and neuroplasticity, the brain’s ability to form new, more efficient pathways through repeated habits and structure.

The Royal College of Psychiatrists and NHS both recommend these approaches, emphasising that therapy and coaching remain useful at any age for maintaining attention and memory function.

What research says about ageing and ADHD

Long-term studies suggest that ADHD doesn’t “fade” with age but people often experience fewer crises as they become better at predicting and managing their difficulties.

Recent research from PubMed (2025) indicates that ADHD itself doesn’t accelerate dementia risk, though adults may face a slightly higher likelihood of mild cognitive impairment if executive-function challenges remain untreated. This underscores the value of ongoing review and flexible support across adulthood.

Takeaway

ADHD memory problems are usually lifelong, but their impact doesn’t have to be. With consistent strategies, therapy, and self-awareness, adults can turn forgetfulness into something manageable, proving that while ADHD stays, its influence can shrink. The goal isn’t perfection, but progress through structure, support, and self-compassion.
