According to research from King’s College London, up to 90% of adults with autism in the UK remain undiagnosed. This means millions of people may be living with perceptual differences without realizing it, the Daily Mail reports.
Clinical psychologist Lisa Williams, founder of The Autism Service, shared seven signs that often appear in adults but are frequently missed.
Here are the signs to watch for:
- Rigid routines. These routines create a sense of security, but any changes can trigger anxiety.
- Workplace challenges. People often find adapting to new environments, navigating office politics, or participating in group meetings particularly difficult.
- Social cues. Difficulty with social cues can include insufficient eye contact, taking jokes literally, discomfort with small talk, and trouble with personal boundaries.
- Romantic relationships. In relationships, people may have difficulty expressing feelings, interpreting flirting, and sharing personal space; many feel more comfortable with partners who understand their needs and are open to communication.
- Sensory sensitivity. Sensory sensitivity can cause strong reactions to noise, bright lights, certain smells, or clothing textures.
- Difficulty with change. Changes such as moving, starting a new job, or learning new technologies can be especially exhausting.
- Intense interests. Highly focused interests or hobbies can sometimes dominate conversations and become the main focus of attention.
Why It Matters
According to Lisa Williams, the right approach from managers—clear instructions, effective communication, and flexible schedules—can help these employees achieve high performance.
Autism is not a disease but a spectrum of traits that people are born with. Some require minimal support, while others need ongoing assistance.
The Scope of the Problem
An analysis of medical records revealed that among adults aged 40 to 59, 89% lack a diagnosis, and in the 60 to 70 age group, this figure rises to nearly 97%. In contrast, among youth under 19, the rate is only 23%.
Experts warn that the lack of timely recognition means many adults remain without the necessary support. This leads to social isolation, health problems, and gaps in public policy.
