Navigating healthcare can be challenging for anyone, but for autistic individuals, abstract or vague medical advice can be particularly confusing. Literal thinking means processing information exactly as it is stated, without inferring implied meaning. According to NHS England’s More Than Words guide, autistic people may struggle when healthcare professionals use figurative or open-ended phrases such as “take it easy” or “monitor your symptoms”. This can lead to misunderstandings, anxiety, or reduced engagement with care plans.

What the Research Shows

Evidence from NICE guidance highlights the importance of clear, structured, and literal communication in healthcare. Ambiguity can make it difficult for autistic adults to interpret next steps or understand when to seek follow-up care. The National Autistic Society adds that direct, concrete explanations reduce anxiety and resistance, while vague or abstract advice can heighten stress or disengagement.

Recent research supports these findings. A 2025 PubMed Central review found that difficulties interpreting non-literal and abstract language often affect understanding of medical instructions. A related study in PubMed identified unclear communication as a leading cause of healthcare misunderstanding and non-adherence among autistic adults.

The Autistica Alexithymia resource notes that autistic people may also find it difficult to interpret internal states or emotional cues, which complicates communication with healthcare professionals. According to Berkshire Healthcare NHS, healthcare discussions should be supported with written summaries, visual information, and time for clarification to improve understanding.

NICE’s 2025 PDF guideline on autism management further reinforces this, advising healthcare staff to use predictable and non-figurative communication when explaining medical plans and decisions.

Practical Implications

Healthcare providers can make communication clearer and more accessible by:

Avoiding idioms, metaphors, or ambiguous phrases.

Offering written care plans alongside verbal instructions.

Using visual aids to explain steps, such as medication schedules or follow-up appointments.

Allowing extra time for discussion and checking understanding.

Giving explicit examples rather than general advice.

These adjustments align with NHS recommendations and NICE guidance for autism-inclusive healthcare communication and are proven to improve adherence, confidence, and trust in medical settings.

Takeaway

Literal thinking can make abstract or vague healthcare plans difficult for autistic individuals to understand, but structured, direct, and visual communication can make a significant difference. Clear healthcare information empowers autistic people to participate confidently in their care. To learn more about evidence-based autism understanding and screening, visit Autism Detect.
