Understanding AuDHD: When Autism and ADHD Co-Occur

This page is for individuals who identify with, or have been told they may have, both autism and ADHD. At Reframe Psychology, we have specialist knowledge of the unique experience of AuDHD and the particular challenges it brings.

What Is AuDHD?

AUDHD is an informal but increasingly used term to describe individuals who have both Autism Spectrum Condition (ASC) and Attention Deficit Hyperactivity Disorder (ADHD). Research suggests that around 50–70% of autistic people also meet criteria for ADHD, and vice versa, making co-occurrence the rule rather than the exception for many neurodivergent people.

At Reframe Psychology, we recognise that AUDHD is not simply the sum of autism plus ADHD. The interaction between the two experiences creates a distinct and often complex profile that requires specialist understanding, one that goes beyond treating each condition separately.

Historically, a diagnosis of autism could exclude an ADHD diagnosis and vice versa. This has now changed, and dual diagnosis is recognised in both DSM-5 and ICD-11.

Specialist Knowledge of AuDHD

Our clinicians have specialist training and direct clinical experience working with AuDHD individuals across the lifespan. We understand that the AuDHD profile is not simply a combination of two checklists, it has its own distinct characteristics, challenges, and strengths.

This specialist knowledge means we are able to:

• Recognise AuDHD presentations that may not fit neatly into standard diagnostic criteria for either condition alone
• Understand how autistic demand avoidance, ADHD impulsivity, and sensory sensitivities interact and amplify one another
• Identify the ways in which ADHD traits can mask autistic traits, and autistic traits can mask ADHD, leading to missed or late diagnosis
• Tailor assessments and therapeutic support to the specific AUDHD profile rather than applying generic neurodivergent frameworks
• Work with the whole person, including their strengths, coping strategies, identity, and mental health, rather than focusing solely on deficits

We also recognise that many AuDHD individuals reach adulthood without a diagnosis, having spent years developing elaborate coping strategies , often at significant personal cost. Our assessments and therapeutic work are designed to be validating, thorough, and genuinely useful, not just a label, but a foundation for understanding yourself more fully.

The Internal Conflict of AuDHD

One of the most distinctive and least discussed aspects of AuDHD is the experience of internal conflict, where the autistic and ADHD parts of a person’s neurology actively work against one another. This is not a metaphor; it is a lived, daily experience that can be profoundly exhausting and confusing.

The result of this internal tug-of-war can include chronic indecision, difficulty initiating tasks, emotional dysregulation, and a sense of being permanently at odds with oneself. Many AuDHD individuals describe feeling like they are “fighting themselves”, wanting structure but being unable to stick to it; craving novelty but finding change distressing; starting projects with intense energy and then becoming overwhelmed by the detail required to complete them.

This internal conflict is frequently misread as laziness, inconsistency, or emotional immaturity, both by others and by the individual themselves. Understanding it as a neurological reality, rather than a character flaw, is often one of the most powerful reframes our clients experience.

Masking in AuDHD: A Double Layer

Masking, the conscious or unconscious suppression of neurodivergent traits in order to appear neurotypical, is well-documented in autism. In AuDHD, masking takes on an additional layer of complexity, because individuals may also be masking their ADHD traits simultaneously, or using one neurotype’s traits to mask the other’s.

How AuDHD Masking Can Look

• Using ADHD-driven talkativeness and social energy to appear more socially comfortable than they are (masking autistic social anxiety)
• Using autistic rule-following and routine to appear more organised and focused than they are (masking ADHD dysregulation)
• Performing attentiveness in conversations while internally struggling to follow the thread
• Suppressing stimming, movement needs, or sensory reactions in professional or social settings
• Scripting conversations and social interactions in advance to reduce the cognitive load of real-time processing
• Appearing highly competent in structured environments while experiencing significant internal distress

This double-layered masking is one of the primary reasons AuDHD is so frequently missed, particularly in women, girls, and those assigned female at birth, who are socialised to mask more thoroughly from an early age. It is also why many AuDHD individuals present as “high functioning” to the outside world while experiencing significant distress privately.

The long-term cost of sustained masking is well-evidenced: it is associated with autistic burnout, anxiety, depression, identity confusion, and a profound disconnection from one’s own needs and feelings. At Reframe Psychology, our therapeutic approach actively works to reduce the need for masking, not by encouraging people to “unmask” in unsafe contexts, but by helping them understand their own patterns, build self-compassion, and create environments where they can be more authentically themselves.

Compensating in AuDHD: The Hidden Workload

Closely related to masking, but distinct from it, is compensating, the active strategies AuDHD individuals develop to manage the functional challenges. Where masking is primarily about social presentation, compensating is about getting through the day.

AuDHD individuals are often remarkably resourceful and intelligent compensators. Over years, sometimes decades — they develop elaborate systems, workarounds, and habits that allow them to function at a level that may appear entirely typical to others. This is frequently why they reach adulthood, or even middle age, without a diagnosis.

Common AuDHD Compensating Strategies

The problem with compensating is that it is cognitively and emotionally expensive. The mental energy required to maintain these strategies, on top of the already elevated cognitive load of AuDHD, leaves little capacity for anything else. Many AuDHD individuals describe a sense of constantly “running on empty”, performing well in some areas of life while other areas quietly collapse.

Compensating strategies also tend to break down under stress, illness, major life transitions, or cumulative fatigue, which is often when AuDHD individuals first seek support. Understanding which strategies are genuinely helpful and which are maintaining distress is a key part of the therapeutic work we do at Reframe Psychology.

AuDHD Assessment at Reframe Psychology

Our AUDHD assessments are carried out by experienced clinical psychologists who understand the complexity of dual diagnosis. We do not assess for autism and ADHD as separate, sequential processes — we approach the assessment holistically, with an understanding of how the two profiles interact in the individual in front of us.

Our assessments include:

• A detailed clinical interview covering developmental history, current functioning, and the specific challenges of AuDHD interaction
• Standardised autism- and ADHD-specific assessment tools, interpreted within an AuDHD framework
• Exploration of masking, compensating, and internal conflict as part of the clinical picture
• Consideration of co-occurring conditions including anxiety, depression, trauma, and burnout
• Collateral information from family members or close others where appropriate and consented
• A comprehensive written report with clear formulation and practical recommendations
• A feedback session to discuss findings, ask questions, and begin to make sense of your profile

We assess adults, young people, and children, and we are experienced in working with individuals who have previously received partial diagnoses, incorrect diagnoses, or no diagnosis at all despite longstanding difficulties.
