High-functioning anxiety is not a DSM-5-TR diagnosis. It is, however, a clinically meaningful pattern that presents regularly in therapy rooms — particularly among women — and one that is frequently missed precisely because the person carrying it is still performing well by external measures.
The core feature is that anxiety is not incapacitating the individual. It is driving her. The hypervigilance keeps her from missing details. The catastrophising drives over-preparation. The fear of failure produces results that earn praise and additional responsibility. From the outside, it presents as conscientiousness. From the inside, it is a motor that cannot switch off.
Left unaddressed, this pattern is one of the most consistent precursors to burnout. Maslach and Jackson's (1981) three-component model — emotional exhaustion, depersonalisation, and reduced personal accomplishment — maps predictably onto the endpoint of sustained high-functioning anxiety, particularly in women carrying disproportionate relational and occupational load.
From a polyvagal perspective (Porges, 2011), the pattern represents a chronically mobilised sympathetic state. Recovery requires not only cognitive intervention but physiological downregulation — a point that has practical implications for treatment planning. CBT and ACT both have evidence bases for this presentation; somatic approaches are increasingly understood as necessary rather than supplementary.
Late-diagnosed neurodivergent women are particularly vulnerable to this pattern, carrying the additional load of masking on top of anxiety management. Autistic burnout, as described by Raymaker et al. (2020), has distinct features requiring a differentiated clinical response.
