Autism assessments for adults

Autism, also known as Autism Spectrum Disorder (ASD), is a special way that some people’s brains work differently. It can make things like talking, making friends, and understanding feelings a bit tricky. People with autism might have trouble knowing how others feel or knowing when to talk or stay quiet. They might find it hard to understand social cues or expressing their feelings. An autism assessment can help people to understand themselves better and help them find the right kind of support and help they need.

Identifying autism in adults

Signs and symptoms of autism vary widely. While people with autism often experience the world differently from others and can share some common challenges, everyone is unique and faces different difficulties. This is why autism diagnosis should only be carried out by experts.



Autistic people may have difficulty understanding social cues, making friends and fitting into social situations


Many autistic individuals experience heightened levels of anxiety due to sensory sensitivities, social challenges and unpredictability


Autistic individuals may be misunderstood because their communication and social behaviours can differ from what is expected


Establishing and maintaining a strict routine is often important for autistic people as changes to the routine can cause distress


People with autism may struggle expressing their thoughts and feelings verbally or non-verbally


Many autistic people tend to be introverted, finding comfort in quieter settings or on their own


Maintaining eye contact can be a challenge for autistic people due to sensory overload or difficulties with social engagement


Some autistic people may have issues with their speech such as delays, unusual speech patterns or difficulty initiating and sustaining conversations

Symptoms of autism usually start in early childhood and persist into adulthood, although the way in which these symptoms present themselves can change as a person gets older.

Although many people are diagnosed as children, this is not true for everyone. Many people only notice autistic traits as they get older, and an adult autism assessment can help in this case.


While each person with autism is unique, it can be useful to listen to the feedback of other people who have been through similar experiences. The testimonials below are a small selection from several patients who very kindly agreed to feature in this section (certain personal details have been removed).

I am incredibly grateful for the autism assessment with Dr Maritan, as it led to a life-changing discovery. While I initially expected to be diagnosed with autism, the doctor went above and beyond in her evaluation and identified that I had bipolar disorder. Her expertise and attention to detail allowed for an accurate diagnosis, which was pivotal for me. The whole team’s compassionate support and personalised advice have guided me towards effective treatments and strategies. Although the result was unexpected, it ultimately set me on the right path. I highly recommend that anyone seeking clarity and support gives it a shot, as it can genuinely make a difference.
Before my assessment, the only help I ever managed to get was a prescription for antidepressants. I think my GP did want to help, but they told me they’ve had patients on waiting lists for over 2 years and now with Covid it’s even worse. It was a lot of money, but the assessment with Harley Psychiatrists led to an autism diagnosis that changed everything. I have finally started therapy that’s actually tailored to my needs, and I am learning to stop blaming myself for “not trying hard enough”. The clinic’s understanding and guidance have empowered me to embrace my strengths and manage my challenges effectively. I highly recommend their assessments to anyone seeking the right support and understanding.
The assessment at Harley Psychiatrists was done at a complete low point in my life, and to be honest I didn’t think it would change anything. I was so wrong and I’m so glad my parents talked me into it. Dr Nigel did diagnose me with Asperger’s but also asked me to come back for an ADHD assessment too, and it turns out I have both. With Dr Nigel’s support, I started treatment for ADHD, and it has made a big positive difference in my life. I got a shared care agreement so I get prescriptions from my GP and the whole process has made me feel like a different person.

It can be daunting to reach out for help with autism testing, but when the difficulties associated with autism are impacting on your daily life, it can be helpful to speak with a psychiatrist specialising in autism diagnosis.

There are many autism testing tools and processes available, and not all are suitable for each person. This is why it is important for autism assessments to be bespoke and developed around your specific difficulties. Our psychiatrists will take into account factors such as your physical health, family history and impact of symptoms. Particular attention will be paid to comorbidities – related conditions (such as anxiety or mood disorder) so that the diagnosis is made as accurately as possible.

Following an autism diagnosis, your psychiatrist will consider your individual needs when suggesting any kind of treatment plan to manage your specific symptoms. This Autism treatment plan will be personalised to you. Although an “autism cure” doesn’t exist, with support it is possible to lessen the impact of many associated symptoms.

Common questions and answers

Types of autism

It is important to understand that autism is a spectrum, which means there as well as different sub-types and categories of autism, each person may have different skills, interests and needs.

Autism Spectrum Disorder (ASD) can include a wide range of characteristics and behaviours that can vary from person to person. Some people may have more significant challenges with communication and social interaction, while others may excel in certain areas and have milder difficulties.

The spectrum also includes different sub-types, such as Asperger’s syndrome, which is characterized by average to above-average intelligence and a focus on specific interests.

By recognizing the diverse nature of autism, we can appreciate the unique strengths and challenges each person brings and therefore their support and interventions can be tailored accordingly.
