Neurodiversity and Mental Health in High Performers: What Referrers Might Miss, and How to Identify It Early
Medically reviewed by Paul Hornsey
Neurodivergence and mental health are distinct clinical domains, yet can often be intertwined1. In individuals performing at high levels – executives, entrepreneurs, public figures, and members of dynastic families, for example – the interplay between attentional differences, autistic traits, or dyslexia may be concealed behind polished compensatory strategies2-7. While these adaptations can fuel achievement, the chances of experiencing comorbidities with conditions such as anxiety, depression, and substance reliance also increases8.
Referrers such as clinicians, private GPs and psychiatrists, as well as other medical advisors may experience challenges in recognising these subtleties early, and knowing when escalation to specialist, integrated care is required. Failure to detect the signals may risk not only individual wellbeing but also family cohesion, succession planning, and organisational stability.
Co-occurrence Between Neurodiversity and Mental Health
Evidence suggests the overlap between neurodevelopmental and psychiatric conditions9. Adults with ADHD face significantly higher lifetime risks of depression, anxiety, and substance misuse9-11. Conditions such as Autistic Spectrum Disorder (ASD) are often complicated by co-occurring psychiatric conditions12-16, and it is estimated that 70-80% of adults with autism also meet the diagnostic criteria for at least one other psychiatric condition17-19. Dyslexia, frequently reduced to an educational issue, has been linked to persistent self-esteem difficulties and a higher prevalence of depression in adulthood20-21.
In individuals who perform at high levels, the impact of these overlaps can be magnified. Undetected, unmanaged neurodiversity may destabilise marriages22-24, intensify intra-family disputes, or precipitate reputational crises as maladaptive coping strategies — from stimulant reliance25-26 to compulsive work – shift from adaptive strategies to embedded patterns of behaviour.
Masking in High Performers: The Hidden Toll of Compensation
A defining clinical complexity is masking: the deliberate or unconscious effort to conceal attentional, communicative, or sensory differences27-28. Those navigating the upper echelons of the c-suite, for example, may mask their conditions by constructing refined professional personas, characterised by meticulous preparation, polished presentation, or relentless productivity.
But masking can also be costly – sustained concealment is known to contribute to development or worsening of burnout, exhaustion, disconnection from one’s identity, and psychological distress29-30. Interestingly, studies suggest women with ADHD are frequently misdiagnosed with anxiety or depression because their masking strategies emphasise over-organisation and perfectionism31-32. Men, conversely, may present with irritability, aggression, or risk-taking behaviours that are mistaken for personality traits rather than markers of executive dysfunction33-35.
Paradoxically, some of these traits – such as high energy, risk tolerance, or impulsive decision-making – may have played a role in driving professional achievement or entrepreneurial success. However, when unrecognised or unmoderated, the same traits can become destabilising under sustained pressure or emotional strain.
Subtle Clinical Nuances That Signal Neurodiversity
Among high-achieving professionals with undetected or unmanaged neurodiversity, cues may rarely appear in isolation but can emerge as patterns within professional or relational contexts, requiring contextual interpretation, such as27-28,36-40:
General practice may not always recognise such nuanced patterns – potentially as a result of brief consultations, reliance on self-reporting, or symptoms that emerge differently under stress or in context-specific situations.
In both NHS and private settings, resource constraints and competing demands can impede in-depth assessment (e.g. ADHD in primary care programmes face constraints around time, staffing, and recognition)41-43.
For family offices or legal advisors, it is possible for these dynamics to threaten financial security, continuity, or reputation if latent vulnerabilities remain undetected.
Psychiatrists and specialist neurodiversity and mental health clinicians, meanwhile, may wish to adopt a neurodevelopmental lens to look beyond symptom clusters and examine attentional regulation, sensory processing, and behavioural compensation – factors that could blur traditional diagnostic boundaries. Early recognition of these patterns allows for more targeted treatment planning, and more informed decisions about when referral to a specialist service, such as Harbor London, is appropriate.
When Standard Care Isn’t Enough: Recognising Thresholds for Specialist Escalation
Escalation does not always mean over-pathologising. Instead, it can be an effort to recognise when conventional interventions are no longer sufficient. In practice, this might look like the client who has completed multiple rounds of CBT and medication adjustments yet continues to experience recurring burnout or renewed substance use; or the executive whose volatility begins to affect decision-making and family stability despite ongoing therapy.
Scenarios that warrant specialist or one-to-one residential care may include8, 25-26, 44-48:
Harbor London’s one-to-one, medically led, multidisciplinary model is designed for precisely these contexts, offering integration and discretion beyond standard outpatient frameworks.
Why One-to-One Care Improves Outcomes
Residential one-to-one treatment allows continuous observation and can help clinicians distinguish between substance-driven mood swings and attentional dysregulation linked to ADHD. Interdisciplinary teams – psychiatry, psychology, occupational therapy – work collaboratively rather than in silos, helping to avoid the fragmentation that can often undermine outcomes.
Harbor’s London base adds a further advantage. Unlike retreat-style models that remove individuals from their context, treatment within the city allows coping strategies to be tested in the same environment clients will return to. For executives and public figures, this can prevent the false reassurance a temporary retreat may bring, thus aiding in sustainable reintegration.
Towards a More Informed Referral Pathway
For healthcare professionals, recognising the intersection of neurodiversity and mental health is not about simply reducing clients to diagnostic labels. It likely requires acknowledging that conventional psychiatric frameworks may often miss individuals who have masked vulnerabilities for decades.
For family offices and legal advisors, the priority is continuity: of wellbeing, of family systems, and of reputation. Identifying nuanced patterns that suggest neurodiversity is a form of preventive diligence can allow for proactive rather than reactive intervention.
By reframing these presentations not as failings but as complex, interwoven conditions requiring integrated care, referrers can act decisively – protecting both individuals and the systems that depend on them.
Towards Earlier Recognition and Better Outcomes
Neurodiversity in high-performing individuals, those living their lives in the public eye, or in high-stress roles can often remain invisible until masking or maladaptive coping strategies collapse. For referrers, challenges may lie in recognising subtle clinical and behavioural indicators, and knowing when escalation to specialist care is warranted.
Harbor London’s one-to-one, multidisciplinary model provides the precision, discretion, and integration required for complex cases. For clinicians and advisors, the task is to see neurodiversity and mental health not as barriers to success, but as a lens – one that reveals where achievement and vulnerability intersect, and where timely referral preserves both wellbeing and legacy.
