Why choose the Fitzrovia Psychology Clinic

At The Fitzrovia Psychology Clinic, we combine specialist clinical expertise with a genuinely supportive and neuroaffirmative approach.

Our team is made up of highly experienced Clinical Psychologists who provide evidence-based, compassionate and personalised assessments designed to help teenagers better understand how they think, communicate and experience the world.

Adolescence is a period of significant emotional and social development. Our assessments consider the wider context of each young person’s life, recognising that autism can present differently during the teenage years.

What sets our clinic apart is the balance between clinical expertise and a human, relational approach. We do not treat assessment as a high-volume or transactional process. Instead, we prioritise thorough, high-quality assessments that provide clarity, understanding and practical next steps for both teenagers and their families.

Our approach includes:

Fully individualised assessments from first contact through to post-diagnostic support
A neuroaffirmative approach focused on strengths, understanding and individual needs
Clear, consistent communication throughout the assessment process
Structured, evidence-based diagnostic methods
Detailed clinical formulation rather than a checklist diagnosis
Personalised recommendations for home, education and everyday life
Ongoing post-assessment guidance and support options

We treat every young person as an individual, not a diagnosis, with the aim of creating clarity, confidence and direction for the future.

Understanding your teenager

Every teenager develops differently, but some young people experience ongoing differences in communication, social interaction or sensory processing that may indicate autism.

For some families, these differences have been present since childhood. For others, they become more noticeable during adolescence as social expectations, friendships and academic demands increase.

You may recognise:

Finding it difficult to make or maintain friendships
Social situations feeling confusing, exhausting or overwhelming
Difficulty understanding social cues, humour or implied meaning
Sensory sensitivities to noise, light, textures or busy environments
A strong preference for routine and predictability
Deep focus on particular interests or hobbies
Feeling anxious when routines change or plans are disrupted
Difficulties with organisation, planning or managing daily demands
Emotional exhaustion, masking or burnout after school
Feeling different from peers despite wanting to fit in

An autism assessment can help build a clearer understanding of these patterns, allowing your teenager and your family to move forward with greater confidence and the right support.

FAQ

What signs suggest that my teenager should have an autism assessment?

Many parents seek an assessment after noticing long-standing differences in how their teenager communicates, interacts socially or responds in everyday situations. This may include difficulties with friendships, sensory sensitivities, a preference for routine, anxiety in social situations, intense interests, emotional exhaustion or feeling overwhelmed by change. An assessment can help determine whether these experiences are consistent with autism.

What happens during a teenage autism assessment?

Every assessment is tailored to the individual teenager and is never based on a single test or questionnaire. The process may include clinical interviews, structured diagnostic tools, behavioural observations and standardised questionnaires. We take time to understand your teenager’s developmental history, current experiences and overall wellbeing to build a complete clinical picture.

Will parents or carers be involved in the assessment?

Yes. Parents or carers play an important role by providing information about their teenager’s developmental history, early childhood and current experiences. We also ensure that the young person’s own perspective remains central throughout the assessment process.

How long does an autism assessment for teenagers take?

The assessment is completed over a small number of structured appointments to ensure a thorough understanding of your teenager’s experiences. Once the assessment is complete, your report and feedback session are typically provided within 7–10 working days.

What happens after a diagnosis?

Following the assessment, you will receive a detailed diagnostic report together with a feedback session led by your clinician. You will also receive personalised recommendations, which may include educational support, reasonable adjustments, therapy options, psychoeducation or guidance on accessing further services where appropriate.

Can the assessment help with support at school or college?

Yes. A formal diagnosis and comprehensive clinical report can help schools or colleges better understand your teenager’s needs and consider appropriate support or reasonable adjustments where appropriate.

Can autism be diagnosed during the teenage years?

Yes. Some young people are diagnosed during adolescence because increasing social, academic and emotional demands make autistic traits more noticeable. Others may have developed coping strategies that masked their difficulties earlier in childhood. A comprehensive assessment can provide greater clarity regardless of when concerns arise.
