Why Consider a Combined Adult ADHD & Autism Assessment?
ADHD and Autism often co-occur, but their traits can sometimes mask or complicate one another. A combined assessment allows for a comprehensive exploration of your neurodevelopmental profile in a single pathway, ensuring that no aspect of your experience is overlooked.
- Executive functioning difficulties (organisation, planning, starting tasks)
- Emotional regulation challenges and intense internal experiences
- Sensory differences and sensitivities to environment
- Social communication difficulties and social fatigue
- Experiencing frequent burnout and overwhelm
- Significant difficulties managing the demands of daily life
By looking at both profiles together, you gain a more complete understanding of your unique strengths and how best to navigate future support.

Understanding ADHD
What is ADHD?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects how people process information and manage their actions. In adults, it often presents as a unique set of challenges and strengths related to attention, executive function, and emotional regulation, which can impact various aspects of daily life, from career to personal relationships.
Common Adult ADHD Experiences
- Difficulty concentrating on tasks
- High levels of distractibility
- Frequent forgetfulness in daily life
- Poor organisation and clutter management
- Time management and planning difficulties
- Internal or physical restlessness
- Impulsivity in decision-making
- Challenges with emotional dysregulation
Understanding Autism
Defining Autism in Adulthood
Autism is a lifelong neurodevelopmental difference that shapes how an individual perceives and interacts with the world. In adults, autism often manifests as unique ways of processing information, communicating, and experiencing sensory environments, frequently accompanied by deep interests and a preference for structured routines.
Common Adult Autism Experiences
- Differences in social communication
- Sensory sensitivities
- Preference for routine and predictability
- Deep interests and areas of focus
- Social fatigue
- Difficulties navigating unspoken social expectations
Can You Have Both?
It is increasingly recognised by researchers and clinicians that ADHD and Autism frequently co-occur. While they were historically viewed as separate diagnoses, we now understand that many individuals meet the criteria for both—a profile often referred to as AuDHD. Identifying both aspects of your neurodevelopmental profile is essential for a complete understanding of your experiences.
Co-occurrence
Research shows frequent co-occurrence between ADHD and Autism.
Executive Function
ADHD may explain difficulties with attention, organisation, and focus.
Lived Experience
Autism may explain unique social communication and sensory experiences.
Daily Impact
Both profiles contribute to day-to-day challenges as well as unique strengths.
Signs You May Benefit from a Combined Assessment
If you identify with several indicators across these areas, a combined ADHD and Autism assessment can provide the clarity needed to understand your unique neurodevelopmental profile.
Attention and Executive Functioning Difficulties
- Difficulty starting tasks or staying focused on one thing at a time.
- Struggling with prioritisation, time management, or organisation.
- Impulsivity in decision-making or conversations.
- Forgetfulness in daily activities or losing items frequently.
Social Communication Differences
- Feeling like you are 'masking' or performing in social situations.
- Difficulties with unspoken social rules or small talk.
- Feeling exhausted after social interactions (social burnout).
- Differences in eye contact or interpreting body language.
Sensory Differences
- Heightened sensitivity to noise, light, textures, or smells.
- Under-sensitivity or seeking specific sensory input.
- Sensory overload in busy or loud environments.
Emotional Regulation Challenges
- Intense emotions and difficulty returning to a calm state.
- Rejection sensitivity or a strong response to perceived criticism.
- Frequent feelings of overwhelm or burnout.
- Difficulty managing frustration or rapid mood shifts.
Routine and Flexibility Differences
- A strong preference for predictability and routine.
- Difficulty with unexpected changes to plans.
- Deep interests or focus on specific topics.
Masking and Late Identification
Masking, or camouflaging, involves suppressed innate neurodivergent traits and adopting neurotypical social behaviours to fit in or stay safe. This often leads to late identification, as individuals may appear to be managing well outwardly while experiencing significant internal struggle.
- Rehearsing conversations in advance
- Hiding sensory discomfort in public
- Over-preparing for social situations
- Copying others' social behaviours
- Working much harder than others to manage daily demands
The Impact of Long-Term Masking: Persistent masking is exhausting and can lead to intense social fatigue, anxiety, burnout, reduced self-esteem, and complex mental health difficulties. Identification is the first step toward living more authentically.

Common Questions About Combined Assessments
Why choose a combined assessment instead of separate ones?
A combined assessment is often more efficient and accurate. Because ADHD and Autism frequently co-occur and share overlapping traits, seeing them together allows our clinicians to understand how they interact uniquely in your life, leading to more integrated and helpful recommendations.
How long does the combined assessment process take?
The process involves pre-assessment questionnaires followed by a clinical consultation. Typically, the comprehensive diagnostic report is delivered within 4-6 weeks of your final clinical appointment, ensuring a thorough review of all evidence.
Will I receive a formal diagnostic report?
Yes. You will receive a detailed professional diagnostic report that outlines the assessment findings, confirms any diagnoses, and provides a clear summary of your neurodevelopmental profile alongside personalised recommendations for support.
What if I've been masking my traits for years?
Our clinicians are specialists in identifying late-diagnosed neurodivergence and understand the impact of masking. We look beyond surface behaviours to explore your internal experiences and lifelong patterns, validating the effort you've used to navigate social and daily demands.
Is the assessment pathway evidence-based?
Absolutely. Our assessments follow gold-standard clinical guidelines and use validated diagnostic tools. This ensuring that your assessment is robust, professional, and widely recognised by healthcare providers and workplaces.
