If you live with ADHD, you might know that uneasy moment hours later, Did I lock the door? Did I turn the stove off? According to NHS guidance on living with ADHD (2024), this kind of forgetfulness isn’t about negligence. It’s caused by executive dysfunction and working memory deficits, which affect how your brain holds, sequences, and recalls tasks, especially under distraction or stress.
The science behind everyday forgetfulness
The Royal College of Psychiatrists (2023) explains that ADHD disrupts prospective memory, the ability to remember to do things in the future, such as locking up or switching off an appliance. When attention is suddenly pulled elsewhere, the final action step often slips through unnoticed.
The NICE Guideline NG87 (2023 update) confirms that this happens because of time-blindness and task transition difficulties, which interrupt the brain’s internal “checklist”. These neurological differences make safety lapses common, particularly when juggling multiple tasks or environments with lots of sensory input.
What research shows
A 2023 study in Frontiers in Psychology found that adults with ADHD experience significantly more lapses in everyday safety tasks because of prospective memory impairments. When combined with environmental distractions, this can lead to anxiety and repeated self-doubt (“Did I really do it?”).
Similarly, Lancet Psychiatry (2022) reviewed clinical evidence showing that structured strategies, habit-stacking, visual cues, digital reminders, CBT, and ADHD coaching, greatly reduce these lapses. Psychoeducation and compassion-based approaches also lessen guilt, helping people build confidence and practical consistency.
Practical ways to stay safe and calm
Experts from NHS and RCPsych recommend pairing memory supports with routine cues:
- Use visible reminders: Place sticky notes or signs near doors and appliances.
- Add sensory cues: Say aloud, “I’ve locked the door,” or take a quick photo for reassurance.
- Automate when possible: Use smart plugs or auto-lock systems for peace of mind.
- Stack safety checks: Link them to existing habits, e.g., lock up right after turning off lights.
- Reframe mistakes: Forgetfulness is neurological, not moral. Self-kindness builds resilience.
Coaching services such as ADHD Certify offer tailored strategies for developing low-stress safety routines that match ADHD thinking styles, improving both memory and confidence.
The takeaway
Forgetting to lock doors or turn off stoves isn’t about being careless, it’s how ADHD affects short-term and prospective memory. With the right tools, structure, and self-compassion, you can stay both safe and calm, knowing your environment supports your brain rather than testing it.
