Adult Autism Assessment

Comprehensive Private Autism Assessment for Adults

WMI Psychiatry provides private autism assessments for adults throughout the UK. Our comprehensive adult autism assessment pathway is designed to identify whether Autism Spectrum Disorder (ASD) is present, understand how autistic characteristics affect everyday life and provide personalised recommendations for support.

Our assessments are completed by experienced autism clinicians and include a detailed developmental history, clinical assessment, structured autism observation, diagnostic formulation, written reporting and personalised recommendations.

The assessment pathway is delivered across four appointments, allowing time for a thorough evaluation rather than a rushed one-off consultation. The total cost is £875, which is paid across the four appointments rather than as a single upfront fee.

What Is Included in an Adult Autism Assessment?

Our private autism assessment pathway includes:

  • Detailed autism and general mental health assessment

  • Review of questionnaires and supporting information

  • Detailed developmental and risk history

  • Structured autism clinical observation

  • Multidisciplinary discussion

  • Individualised recommendations for work, education and daily life

Signs of Autism in Adults

Many autistic adults have experienced differences throughout their lives but may only seek an assessment later in adulthood. Some people recognise these differences themselves, while others are encouraged to seek an assessment by family members, employers or healthcare professionals.

Common signs of autism include:

  • Difficulties understanding social situations

  • Finding it difficult to develop or maintain friendships or relationships

  • Differences in eye contact or non-verbal communication

  • Literal understanding of language

  • Difficulties recognising social cues

  • Preference for routine and predictability

  • Becoming distressed by unexpected changes

  • Intense or highly focused interests

  • Repetitive movements or behaviours

  • Sensory sensitivities to noise, light, textures, smells or food

  • Sensory seeking behaviours

  • Difficulties understanding or expressing emotions

  • Feeling exhausted after social interaction

  • Feeling overwhelmed in busy environments

  • Difficulties at work, university or in relationships

  • Feeling different from others without understanding why

Many of these characteristics can also occur in adults who are not autistic. A comprehensive assessment is therefore needed to determine whether these differences are consistent with Autism Spectrum Disorder and whether they have had a significant impact throughout life.
