Why do coworkers forget to support someone with ADHD?
At first, colleagues may show understanding when someone discloses they have ADHD, but over time that support can fade. According to recent NHS and NICE evidence, this happens because ADHD symptoms are often misunderstood, fluctuate in visibility, and are influenced by workplace culture rather than intent alone (NICE NG87 – ADHD diagnosis and management). Many employees simply forget ongoing needs when neurodiversity awareness is not built into everyday systems or communication.
Understanding why support fades in the workplace
Studies from 2023–2025 show that inconsistent support for ADHD colleagues often stems from three overlapping issues: awareness, perception, and empathy fatigue.
Limited awareness and invisible symptoms
ADHD can appear “invisible” in adults. Colleagues may see periods of strong focus followed by distraction or disorganisation and interpret this as inconsistency rather than neurological variation. Research from PubMed (Navigating the professional journey for adults with ADHD, 2024) and CIPD’s Neuroinclusion at Work guidance (2024) shows that without regular reminders or structural reinforcement, coworkers tend to deprioritise ADHD adjustments once initial awareness fades.
Empathy fatigue and stigma
Over time, emotional fatigue and subtle stigma can reduce coworkers’ willingness to offer support. Some may view reminders, flexible deadlines, or communication adjustments as unnecessary, especially when ADHD symptoms are not outwardly visible. NICE and NHS workplace resources, including the CNWL ADHD Reasonable Adjustments guidance, highlight that ongoing awareness training and structured adjustments are essential to maintaining inclusion.
Private services such as ADHD Certify provide professional ADHD assessments and post-diagnostic support across the UK, helping adults understand how fluctuating symptoms can affect relationships and consistency at work.
Key takeaway
Coworkers rarely mean to neglect someone with ADHD, but without consistent awareness and formal structures, support often fades. Reinforcing neurodiversity education, maintaining open communication, and scheduling regular check-ins help ensure ADHD accommodations remain reliable and respectful at work.
