The Reality of Being a Twice-Exceptional Adult with ADHD
For the purposes of this article, under the umbrella of ‘twice-exceptional’, I’m going to talk about adults who are twice-exceptional (being formally identified as both gifted and having ADHD), those who aren’t formally identified as gifted, but have high intelligence and are high achievers, as a specific population of people who come to therapy, that we don’t talk about as often.
What “high intelligence” means in this context
High intelligence, in the way I’m using it here, refers to adults who demonstrate unusually strong cognitive abilities in one or more domains, regardless of whether they were formally identified as ‘gifted’ in childhood.
This can include:
- fast pattern recognition
- rapid learning when interested
- sophisticated reasoning or systems thinking
- nuanced emotional and interpersonal insight
- strong capacity for abstract or conceptual thinking
Some of these adults would meet psychometric criteria for giftedness on standardized testing (typically falling within the top few percentiles of reasoning ability), but many would not show up that way because twice-exceptionality (the ADHD part) and lifelong compensation, can obscure the profile.
In clinical practice, high intelligence shows itself more reliably through lived cognition than through test scores: the way someone learns, thinks, processes, and makes sense of the world.
What “high achievement” means in this context
High achievement refers to adults who have produced exceptional output in one or more areas of life, not necessarily across all subjects or domains, and not necessarily without struggle.
High achievement can look like:
- earning advanced degrees,
- excelling in demanding careers,
- building successful businesses,
- producing significant creative work,
- becoming leaders in their field,
- driving innovation or solving complex problems.
It can also include less conventional forms of achievement, such as raising a neurodivergent family while juggling personal ADHD, organizing community initiatives, or functioning at a high level despite chronic executive-function challenges.
The key idea is that these individuals achieve at a level that stands out from their environment, yet their internal experience often looks very different from their external outcomes.
Many are high achievers because they’ve been chronically overcompensating for untreated ADHD or misunderstood giftedness.
Most twice-exceptional adults do not arrive in therapy sharing a ‘giftedness’ label when I take my clinical history, nor do they refer to themselves as highly intelligent or high achieving.
Instead, they arrive overwhelmed, inconsistent, exhausted and frankly quite puzzled by where they have found themselves in life.
For them, their circumstances don’t fit the narrative they have been given about their potential, or of what the world had expected of them.
Of what they’d expected of themselves.
In therapy, some of the things I notice (that become curiosities begging to be explored) include clients who:
- Easily demonstrate fast pattern recognition,
- Can understand new and complex concepts at lightning speed,
- Often have earned advanced degrees, and excel in demanding careers, or have built successful businesses.
They talk about struggles with:
- Internalized or self-directed perfectionism, and enough-ness,
- Completing everyday tasks,
- Articulating how they know what they know, or breaking it down step by step to others (at work for example),
- Not shutting down during emotional overload.
Childhood praise for intelligence created a defining pressure to succeed, and this is what often masked their ADHD traits.
Many coped silently.
The message has been clear: You’re so smart, you should be fine (even pop culture has a dismissing phrase for it – ever been told you have ‘first world problems’?).
When they struggled with anything, they inevitably received the message they should just be grateful and should go fulfil their potential.
This of course teaches the twice-exceptional child, they should just carry on and not complain. A perfect breeding ground for emotional isolation, disdain for relying on or ‘needing’ others and sometimes, a long time struggle to get emotionally close to the ones they love the most.
Loneliness is a great motivator to hide who you really are, in order to fit in.
In adulthood the cost becomes obvious.
The person who is bright and capable, is also inconsistent, struggling with shame and true vulnerability, and shame.
And despite knowing they have, or might have, ADHD, this is the one area they’ve never given much thought too (other than perhaps feeling secretly happy that there is something that makes them more like others in their lives). This is the twice-exceptional profile I see time and time again.
Defining Twice-Exceptionality in Adults
For the purpose of this article: A twice-exceptional adult is someone who is both highly intelligent and neurodivergent, formally identified or not. ADHD is the most common pairing.
Common strengths that alert me that I might have a twice-exceptional client sitting in front of me includes:
- Lightening fast reasoning,
- Creativity across multiple domains (like academics and athletics),
- Curiosity about themselves and others,
- Emotional nuance – they get it,
- Strong perception of patterns.
Common challenges they share:
- Executive functioning difficulties (those without staff, assistants, admins or a stay-at-home partner),
- Ability to stick it out with things deemed boring or of little interest,
- Sensory and emotional overload at the end of the day,
- Difficulty shifting tasks, or task-switching,
- Burnout or crashes after fairly long periods of high quality productivity,
- Vulnerability to shame
The uneven cognitive profile is the hallmark. High intelligence sits beside ADHD, but it sure doesn’t cancel it out.
Signs of a Twice-Exceptional Profile
The adults who resonate with this description often report patterns such as:
- High insight with difficulty implementing change,
- Hyperfocus followed by avoidance,
- Cycles of overwork and crash,
- Feeling misunderstood by peers and partners,
- Frustration with slow or repetitive information,
- Boredom that looks like procrastination,
- A rich inner world that stays internal due to difficulty expressing it,
- Being told they have high potential yet sometimes, low follow-through on the fine details.
Without a non-judgemental language for this profile, these patterns produce shame, rather than understanding.
Mental Health in Twice-Exceptional Adults
Highly intelligent adults with under-treated or untreated ADHD show elevated rates of:
- Anxiety
- Depression
- Perfectionism
- Emotional overwhelm
- Loneliness
- Existential distress
- Burnout
Many adults will finally come to therapy after a significant (usually emotional) crash.
They often report that they worked twice as hard as others to achieve similar results, have difficulty slowing down in other areas, and then blamed themselves for the exhaustion.
Clarity becomes a turning point.
Once the profile becomes visible the person stops attacking themselves for inconsistency and begins designing a sustainable life.
Twice-Exceptional Adults at Work
Common workplace patterns generally include:
- Strong outcomes under pressure with a crash afterward,
- Feeling under-stimulated in steady-state environments,
- Intolerance of inefficiency,
- Difficulty pacing energy over time,
- High creativity without long term consistency,
- Leaving roles once learning plateaus.
These adults thrive in roles with flexibility, novelty, and complexity (like sales, marketing, advertising, freelance or entrepreneurship).
They struggle in systems that prioritize predictability over innovation (like jobs that start off with a comforting structure and predictability, like policing, teaching, nursing or other intense and shift based professions).
The most effective career choices match brain wiring rather than fight it.
Twice-Exceptional Adults in Relationships
Relationships tend to reflect the intensity and complexity of the internal world.
Patterns that appear often include:
- Strong emotional attunement followed by emotional flooding during conflict,
- Difficulty explaining inner reactions (despite trying so hard, they don’t know why if feels so hard),
- Feeling misunderstood by (loving) partners,
- Shutdown during overwhelm that gets interpreted as withdrawal,
- Deep empathy that does not always translate into co-regulation.
Communication work helps the person share their inner experience consistently rather than only during crisis.
Twice-Exceptional Adults as Parents
I notice parenting conversations often expose this profile most quickly and clearly.
Common themes include:
- High reactivity when the child becomes overwhelmed,
- Old shame resurfacing when the child struggles,
- Fear of repeating their own childhood story,
- Deep empathy limited by low bandwidth,
- Intuitive recognition that their child is wired the same way they are.
This awareness becomes healing because it reframes both parent and child.
Why Diagnosis or Self-Identification Often Arrives in Midlife
For those not assessed in elementary school or as an adolescent, the most common reasons include that there was an overemphasis that school performance was the only thing that mattered.
We (clinicians and diagnosticians) rely too much on educators and teachers assistants to be the first ones to point out our kids may be struggling (these kids usually a ‘teachers delight’). The result turns out to be kids who grow into adults with:
- High intelligence masking ADHD,
- ADHD masking intelligence,
- Childhood academic or athletic success became the barrier for identifying other needs,
- Praise for outcomes rather than development of self became a life motivator,
- Lack of emotional vocabulary for intense emotions,
- Lack of adult friends or peers with similar minds.
It’s not necessarily a sudden a-ha, but the period of time after we explore the possibility as part of the why behind their current situation, there is a clear shift that follows. It’s what allows their whole story to begin again.
What Helps Twice-Exceptional Adults Thrive
The most effective support honours both intelligence and neurodivergence.
More helpful approaches include exploring with your client:
- Community with others who think and feel deeply,
- Ensuring your therapist (or you, if you are a therapist reader) is practicing neurodivergent-affirming therapy competently,
- Practical ADHD strategies for executive functioning,
- Medication when appropriate,
- Workload and environment redesign,
- Communication-skill building for emotional overload,
- Strengths-based goal setting, for career and home life.
If you are an individual or couples therapist working with gifted and/or high achieving adults (or partners coupled together), ensure you are co-creating a highly personalized therapeutic alliance to provide treatment that meets your client where they are at (which is sometimes way ahead of you). Ensuring your therapeutic stance and frame (any modality applies here) are provided from a neurodivergent-affirming clinical practice is also be very important.
‘Meeting’ your clients at their pace, which will move much faster than our training prepares us for, requires more collaborative flexibility from you as their therapist.
Belonging reduces burnout.
New skill-building reduces overwhelm.
Self-understanding reduces shame.
In summary,
Twice-exceptional adults are less likely to ask for help, because they may not believe they are supposed to need it.
Once intelligence and ADHD are understood together, the past begins to make sense. Turns out, they were human all along. Creating a future that feels a lot better becomes exciting, rather than another performance-based task.
