Episode notes
Lifelong Anorexia That Was ARFID
- Dr Lennox recounts patients whose lifelong 'anorexia' was reinterpreted as ARFID linked to autism.
- She finds it tragic when autistic needs were missed for decades and misattributed to anorexic 'voices.'
Recognize ARFID’s Distinct Features
- Learn about ARFID: it's not about weight or shape but severe avoidant restrictive intake often with sensory roots.
- Seek ARFID-informed assessment if lifelong food avoidance fits your history.
CPTSD Sometimes Substituted For BPD
- CPTSD became a softer substitute for BPD in some settings, adding to diagnostic confusion.
- Autistic people are more likely to experience trauma, so PTSD/CPTSD can co-occur but are distinct from autism.
