Late Autism and ADHD Diagnosis and Advocacy for Neurodivergent Families [featuring Katherine L’Etang]

Hosted by: Patrick Casale
All Things Private Practice Podcast for Therapists

Show Notes

In this episode, Patrick Casale talks with Katherine L’Etang (A.K.A. @TheNeurodiversityMom) about her journey as a late-diagnosed Autistic and ADHD adult, which is both powerful and relatable, especially for advocates, parents, and neurodiverse professionals.

Here are 3 key takeaways:

  1. Self-advocacy is essential: It's important to seek validating, knowledgeable professionals—and not settle for invalidating experiences, especially when it comes to late diagnosis and mental health support. Doing your homework on assessors and trusting your self-knowledge is crucial.
  2. Diagnosis is just the beginning: Receiving an autism or ADHD diagnosis in adulthood can trigger a profound shift in self-understanding and acceptance, but it may also lead to a period of intensified traits and burnout before healing begins. Giving yourself grace and time is vital.
  3. Vulnerability builds community: Whether sharing her own journey or making decisions about what to share as a parent, Katherine models how public vulnerability can foster collective healing and support—while continually wrestling with questions of privacy and consent, especially for her kids.

More about Katherine:

Katherine L’Etang, also known as @TheNeurodiversityMom, is a late-diagnosed autistic and ADHD content creator who has made it her mission to provide community, inclusion, and acceptance to anyone who is autistic or raising autistic kids. She lives in British Columbia, Canada, with her husband and two kids.
