At Portobello Behavioural Health and Cardinal Clinic, we are seeing a marked increase in people approaching services identifying their difficulty as burnout. For many, the term feels immediately meaningful. It captures exhaustion, loss of motivation, emotional depletion, and a sense of having nothing left to give.
Yet burnout occupies a curious position in clinical and organisational discourse: widely used, culturally resonant, and increasingly medicalised — but not, in itself, a formal diagnosis.
This tension matters. How we conceptualise burnout influences assessment, treatment planning, organisational responses, and ultimately patient outcomes.
What Do We Actually Mean by "Burnout"?
Burnout was originally conceptualised as a work-related syndrome, most commonly characterised by:
- emotional exhaustion
- depersonalisation or cynicism
- reduced sense of professional efficacy
It is recognised in the ICD-11, not as a mental disorder, but as an occupational phenomenon, explicitly confined to the workplace context and intended to be considered only after other mental health conditions have been excluded.
Importantly, burnout:
- does not appear in the DSM-5
- has no agreed diagnostic criteria
- has no validated clinical threshold
Even widely used instruments such as the Maslach Burnout Inventory measure symptoms along a continuum rather than defining a clinical condition. This means that two people may both describe themselves as "burnt out" while experiencing very different underlying processes.
Prevalence: High Numbers, Wide Variation
Research consistently shows high levels of burnout-related symptoms across healthcare and caring professions. Meta-analyses suggest that between a quarter and half of clinicians report significant emotional exhaustion, with even higher figures reported during and after the COVID-19 pandemic.
However, prevalence estimates vary dramatically depending on how burnout is defined and measured. In some studies, rates range from single digits to over 90% within the same population using different thresholds.
This variability highlights a key problem: we are often counting distress without agreeing what we are counting.
Clinical Validity and the Problem of Overlap
One of the most important clinical questions is whether burnout is meaningfully distinct from other psychological conditions — or whether it is better understood as a contextual presentation of them. I have some quite specific concerns around this as Burnout has entered the lay vernacular (self diagnoses on social media for example) in the same way we have seen happen with trauma and neurodiversity. We could argue the plusses and minuses of this but conflation is a real problem.
Burnout and Depression
Burnout and depression share substantial symptom overlap, particularly around fatigue, low mood, cognitive slowing, and loss of motivation. Research consistently shows strong correlations between burnout scales and depression measures.
A landmark study by Schonfeld, Verkuilen, and Bianchi (2019) investigated this question directly across three studies conducted in two countries with different languages. Using confirmatory factor analysis, they found that latent exhaustion—the core component of burnout—and latent depression were highly correlated, with correlations ranging from 0.83 to 0.88. Importantly, their second-order factor analyses indicated that depressive and anxiety symptoms and the exhaustion and depersonalisation components of burnout are reflective of the same underlying distress factor [1].
Clinically, this raises an important risk: what is labelled as burnout may, in some cases, represent undiagnosed or under-recognised depressive illness, particularly when symptoms generalise beyond the workplace. A person who reports exhaustion, loss of motivation, and emotional numbness in multiple life domains—not just at work—may have depression, not burnout. The distinction matters because it changes treatment planning.
Burnout and Trauma
Burnout-like presentations are also common in individuals with trauma histories. Emotional numbing, withdrawal, exhaustion, and reduced capacity to engage can reflect trauma-related adaptations, especially in high-stress or relationally demanding roles.
Without careful assessment, trauma responses can be misattributed to "work stress" alone — potentially delaying appropriate trauma-informed intervention.
Burnout, ADHD, and Neurodiversity
We are also seeing increasing use of neurodiversity-related language in burnout presentations. While this reflects important advances in understanding, it also introduces complexity.
Neurodivergent individuals may experience heightened cognitive load, sensory overwhelm, or difficulties with sustained executive demand. These vulnerabilities can increase burnout risk — but they may also be mistaken for burnout itself.
Consider a clinical example: a neurodivergent therapist with ADHD presents reporting exhaustion, difficulty completing administrative tasks, and feeling ineffective. The surface presentation resembles burnout. However, careful assessment reveals that the core difficulty is not work-related stress but rather the cognitive and organisational demands of documentation and scheduling systems that are poorly suited to their neurodevelopmental profile. The exhaustion stems partly from the constant compensatory effort required to function within neurotypical workplace structures. In this case, the appropriate intervention is not stress management or time off, but rather workplace accommodation, task restructuring, and potentially neurodiversity-affirming support. Labelling this as "burnout" and recommending rest may provide temporary relief but will not address the underlying mismatch between the individual's neurodevelopmental needs and the work environment.
Similarly, popularised terms such as "ADHD" are sometimes used descriptively rather than diagnostically, obscuring whether difficulties reflect attentional differences, stress-related impairment, mood disturbance, or a combination of these.
Why Conflation Matters
When burnout becomes a catch-all label, several risks emerge:
- Diagnostic overshadowing: depression, trauma responses, or neurodevelopmental needs may go unrecognised
- Treatment mismatch: rest or time off alone may be insufficient where deeper clinical drivers are present
- False reassurance: individuals may believe their distress will resolve once work changes, only to find symptoms persist
Burnout can be a starting point for understanding distress — but it should not be the end point of assessment.
A Personal Note
I write about burnout not only as a clinician or business owner but also as someone who has experienced it personally, more than once. In my own case, the term was initially helpful — it gave language to depletion and overload. But clarity only came when I looked beyond the label and examined the contributing psychological, organisational, and personal factors beneath it.
That distinction matters, both clinically and humanly. It has been really important for me to distinguish what belongs where in order for me not only to optimise my work life which matters to me, but also not to blow up other areas of my life.
Towards a More Clinically Useful Approach
For professionals encountering burnout presentations, a few principles may help restore clarity:
- Assess whether symptoms are work-specific or global
- Screen for depression, trauma exposure, and neurodevelopmental factors
- Use burnout language as a descriptive framework, not a diagnosis
- Match interventions to underlying mechanisms, not just surface symptoms
Burnout remains a powerful descriptor of modern working life — particularly in healthcare and caring professions. But if we are to respond effectively, we must hold it with nuance, rigour, and clinical humility.
Burnout tells us that something is wrong. It does not, on its own, tell us what that something is.
