Positive and differential diagnosis of autism in verbal women of typical intelligence: A Delphi study.
Julie Cumin, Sandra Pelaez, Laurent Mottron
PMID 34514874WHAT IT FOUND
Expert clinicians agreed standard autism tools often miss adult women of typical intelligence.
They rely on long assessments, third-party history, and subtle social cues like empathy gaps to distinguish autism from trauma or borderline personality disorder.
Key findings
01Standardized tools like the ADOS and self-report questionnaires were judged inadequate for detecting autism in adult women of typical intelligence, often producing false negatives or being skewed by anxiety.
02Clinicians differentiate autism from borderline personality disorder by examining the nature of social difficulties (needing space vs. fear of abandonment), emotional vocabulary, and the context of self-harm (sensory/routine vs. interpersonal conflict).
03Assessments for these women often require multiple sessions to observe fatigue-induced masking, and rely on external informants to corroborate childhood history, as patients may present as neurotypical initially.

What it does not show
The sample consisted of only 20 experts from Western countries, which may not generalize to other cultural or healthcare contexts. The study relied on expert consensus rather than empirical validation of these diagnostic strategies against a gold-standard outcome. Acquiescence bias may have inflated agreement with the proposed statements. The definition of 'expert' was broad, ranging from 5 to 40 years of experience.
Declared interests
The authors declared no conflicts of interest. The study was conceived based on priorities identified by clinicians.
The easy way to misread this
Do not treat these consensus statements as evidence-based diagnostic criteria with proven accuracy. This study reports what experienced clinicians believe is necessary, not a validated test that reliably distinguishes autism from other conditions in a controlled setting.
