What is autism / ASD?
Autism spectrum disorder (ASD) is a lifelong neurological and developmental condition that affects how a person experiences the world. It can influence everything from:
- Communication and social interaction
- Behaviour and routines
- Sensory processing
- Emotional regulation
- Executive functioning (planning, organisation, decision-making)
Autism is not an illness and does not have a “cure.” Instead, it is a neurodevelopmental difference.
In the UK, autism is recognised as a disability under the Equality Act 2010, meaning individuals with a diagnosis are entitled to reasonable adjustments in education and the workplace.
ASD is described as a spectrum condition, which means its effects vary greatly from person to person. Some people may need significant support in daily life, while others may live independently but still face challenges with social communication, relationships, or workplace settings.
ASD in adults
Autism is often identified in childhood, but because it is lifelong, the characteristics and challenges of ASD continue into adulthood. Many adults live for years without recognising they are autistic, sometimes developing coping mechanisms known as “masking” that hide their difficulties.
In the UK, accessing an ASD assessment through the NHS as an adult can take up to several years. Choosing a private assessment provides quicker answers and earlier access to the right support.
Adults with undiagnosed ASD may face difficulties such as:
- Navigating workplace environments and career progression
- Managing financial or organisational responsibilities
- Building and maintaining personal relationships
- Coping with anxiety, depression, or burnout due to lack of support
Signs of ASD in Adults:
Autism can present differently in adults compared to children, and many adults develop strategies to mask or cope with their challenges. Because of this, identifying and recognising autism spectrum disorder in adults can be difficult.
| Sign | How it Presents in Adults |
|---|---|
| Social cues | Difficulty interpreting tone of voice, body language, or subtle hints |
| Routines | Preference for predictability, distress if routines are disrupted |
| Intense focus | Deep interest in specific topics or hobbies, sometimes to the exclusion of others |
| Sensory sensitives | Discomfort with loud noises, bright lights, crowded spaces, or certain textures |
| Small talk and conversations | Finding social conversations draining or challenging |
| Isolated | Feeling different, misunderstood, or withdrawing socially |
| Challenges with relationships | Struggles with intimacy, miscommunication, or sustaining friendships |
| Planning | Difficulty with executive functioning, managing tasks, or financial responsibilities |

How an ASD Diagnosis or Screening Can Help
Although autism is not something to be “cured,” receiving a diagnosis as an adult can be life-changing. The process provides answers, validation, and access to the right support.
- Clarity and self-understanding: Receiving an ASD can help to provide clarity, finally having an explanation for lifelong experiences and challenges
- Formal diagnosis: A professional ASD assessment is essential for accessing tailored support, accommodations, and services. A private, affordable assessment from Dementech can help to access screening without the excessive wait list.
- Workplace protections: An ASD screening can open eligibility for reasonable adjustments under the Equality Act, such as flexible working or quieter environments
- Improved healthcare and support: Greater recognition from healthcare professionals, therapists, and social services
- Better mental health: Many adults feel relief and validation after diagnosis, reducing anxiety and self-doubt
- Stronger personal relationships: Helps friends, partners, and family understand and support you more effectively

FAQs
Autism is sometimes misunderstood, and adults may wonder whether their experiences are a sign of autism spectrum disorder. An assessment can help to distinguish ASD from other conditions with overlapping traits, such as ADHD, OCD, or social anxiety.
What ASD is:
Autism is a recognised neurodevelopmental condition, with lifelong symptoms often first appearing in childhood.
What autism is not in adults:
- A mental illness (though mental health challenges may co-exist)
- Something caused by upbringing, trauma, or poor parenting

“Dementech Neurosciences is a relatively new clinic specialising in the scientific assessment and treatment of Parkinson’s Disease. It represents a significant development in the treatment of Parkinson’s and has done a great job of establishing itself and its reputation in a short period of time. The premises are extremely well situated in central London, the consultant neurologists are all at the top of their field in their specialisation of the treatment of Parkinson’s Disease, and the clinical and administrative staff are of a similar standard. The atmosphere of the clinic is positive and the results, in the short period of time I have been able to assess, have been similarly positive.”
