What can I do at work to help someone when this was not picked up when they were younger?

Short answer

Do not use late recognition or personal history as workplace evidence.

What this can look like

Personal history is private and does not prove anything about current workplace needs.

Why it can happen

Someone may have adapted, had needs missed or found language later in life; none of that is for a manager to interpret. Keep work conversations in the present and respect privacy.

What might help

Focus on present work conditions, fair support and consent.

What the research helps explain

Australian autism guidance and research on masking describe meaningful differences in sensory experience, communication, routines, transitions and recovery. At work, person-led, context-aware options can improve access without requiring a person to disclose or be identified as autistic or AuDHD.

What can vary

People differ widely in communication, sensory needs, recovery and preferred support. Similar experiences can have other explanations. Do not infer identity, ask for private information or make adjustments conditional on disclosure.

For this situation

For you, ask what support would help now, not why a person did not disclose earlier.
