If you’re curious about high functioning Autism Spectrum Disorder (ASD) and ADHD in adults, you’re in the right place. We’ll be diving into what these terms really mean, identifying some of the signs to look out for, and guiding you towards choosing the right assessment. These neurodevelopmental conditions are often misunderstood, particularly when the signs are subtle or well-masked.
This blog is here to discuss what “high-functioning” really means, highlight common traits, explore overlapping symptoms and guide you toward professional assessment and support. It’s not about labels, it’s about gaining insight into your unique brain and how to support your wellbeing.
What Does it Mean To Be High Functioning?
The term ‘high functioning’ in the context of autism and ADHD isn’t about one’s abilities or intelligence. Instead, it simply suggests that someone doesn’t necessarily show the stereotypical, more obvious symptoms associated with these conditions. People with high functioning autism or ADHD often develop coping strategies that make their symptoms appear less noticeable. However, this doesn’t mean they don’t face challenges or require support.
In fact, some adults with high-functioning neurodivergence may have never been formally diagnosed. They might struggle internally while appearing outwardly “fine.” But beneath the surface, there can be exhaustion and difficulty sustaining relationships, work performance or emotional regulation.
Signs of High-Functioning Autism in Adults
Autism Spectrum Disorder (ASD), commonly known just as autism, is a neurodevelopmental disorder characterised by challenges in social interaction, communication, and repetitive behaviours or interests. Adults with high functioning autism may have more nuanced difficulties in these areas that aren’t immediately obvious.
Common Signs to Look Out For
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects social communication, sensory processing, and behavioural flexibility. Adults with high-functioning autism often face challenges that are less immediately visible, but no less significant.
- Social interaction difficulties – trouble reading facial expressions, body language, or navigating unspoken social rules
- Literal interpretation of language – struggling with sarcasm, jokes, or indirect communication
- A need for routine and predictability – becoming distressed when routines are disrupted
- Intense or niche interests – deep knowledge or focus on particular topics
- Sensory sensitivities – strong reactions to noise, textures, lights, or smells
Other Signs of High-Functioning ADHD to Look For
ADHD is not just a childhood condition. In fact, many adults are only diagnosed later in life; often after years of coping with stress, underachievement or misdiagnosis.
Inattention – difficulty in maintaining focus, being easily distracted, poor organisational skills.
Hyperactivity – Feeling restless, always needing to be doing something, trouble with sitting still.
Impulsiveness – making quick decisions without considering the consequences, interrupting conversations etc.
Can You Have Both Autism and ADHD?
Yes. Autism and ADHD frequently coexist. Research shows that up to 50% of individuals diagnosed with one condition show traits of the other. The overlap can create a unique blend of strengths and difficulties that may go unrecognised without a specialist assessment.
Examples of overlapping traits may include:
- Sensory processing difficulties
- Emotional reactivity
- Difficulty with transitions and structure
- Hyperfocus or interest-based attention
Understanding whether you have traits of one or both conditions is crucial to finding effective strategies and support.
Why an ADHD Assessment is Important
If you’re recognising some of these signs in yourself or someone you know, it might be time to consider an assessment. It’s essential to remember that self-diagnosis can be misleading, and professional evaluation is key in understanding your unique experiences.
While self-diagnosis may feel validating in the short term, only a comprehensive psychological evaluation can provide clarity, confidence and tailored support options.
Going For an Assessment
A full diagnostic assessment typically includes:
- In-depth clinical interviews – exploring your personal and developmental history
- Validated screening tools and diagnostic questionnaires
- Behavioural observations or tasks (if needed)
- Feedback session with a psychologist to explain your results and recommendations
What Happens During an Autism or ADHD Assessment?
Not sure if it’s autism, ADHD or both? A combination assessment can look at the whole picture, checking out symptoms from both sides to give you a clearer understanding.
Taking the Next Step
Recognising the signs and considering an assessment is an important first step. It’s about getting to know yourself better and finding the best ways to manage your unique challenges. It’s not about being put in a box; it’s about discovering more about yourself and how you can make your life even better.
So, remember, everyone’s story is different. Whether it’s high functioning autism, ADHD, or both, getting to grips with your own way of thinking and doing things is empowering. It’s all about embracing who you are, recognising what you’re great at, and getting support where you need it.
High functioning autism and ADHD in adults are complex, nuanced, and often misunderstood. If you resonate with the signs discussed, consider reaching out for an assessment. It’s a step towards not just understanding yourself better but also towards a journey of self-acceptance and growth. Remember, you’re not alone in this journey, and support is always available.
