Red flags
- School refusal with cascading academic failure, family crisis, or child-protection concern — treat as high-stakes functional emergency, not 'clingy personality'
- New or worsening suicidal ideation with comorbid depression or after SSRI start — same-day risk review and activation monitoring
- Adult SeAD missed because the clinician only screens childhood-onset disorders or labels everything 'dependent personality'
- Chronic benzodiazepines as the sole 'treatment' blocking exposure learning and risking dependence
- Extreme family accommodation that maintains disability (parent never leaves child; partner never travels) without a graded plan
- Somatic school-morning symptoms with medical red flags — reassess for organic disease rather than defaulting to pure anxiety
Meet the patient
A 38-year-old woman presents with panic attacks that happen only when her husband travels for work. She cannot sleep alone, texts him dozens of times a day, and has started refusing to let him go. She is embarrassed, has been told it is "just GAD", and her notes carry a decade-old label of dependent personality.[4][6][7]
Two questions are live. Is the central fear separation, rather than panic or worry in general? And has anyone ever actually asked? Adult separation anxiety disorder is one of the most under-recognised diagnoses in the room — not because it is rare, but because nobody screens for it. Miss it and you titrate an SSRI for the wrong formulation for years.[4][5][6]
