Episode 252: Late Autism and ADHD Diagnosis and Advocacy for Neurodivergent Families [featuring Katherine L’Etang]

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.

About the Podcast

The Neurodivergent Entrepreneur
Honest conversations about building a business while Neurodivergent, the self-doubt, the chaos, and everything in between.
The Neurodivergent Entrepreneur is a podcast for ADHD, Autistic, and all other neurodivergent entrepreneurs who are building businesses, creative work, and lives that actually fit how their brains work. Hosted by Patrick Casale, LCMHC, this show is for people who
want to create meaningful work, create outside of the box, grow their impact, and build something sustainable without losing themselves in the process.

Being a neurodivergent entrepreneur can feel like holding a lot of contradictions at once. You may have big ideas, deep passion, creative energy, and a strong desire to do things differently. You may also be navigating burnout, masking, self-doubt, perfectionism, rejection sensitivity, executive dysfunction, inconsistent energy, and the pressure to keep showing up when your capacity is already stretched. This podcast speaks to that reality honestly, because building a business around your brain, your values, and your lived experience can be powerful, complicated, messy, and deeply personal.

Patrick Casale is a chronically ill, AuDHD, mental health therapist, entrepreneur, TEDx speaker, event host, group practice owner, and neurodivergent business owner who has built, grown, burned out, pivoted, and kept going. His work brings together clinical insight, lived experience, business perspective, and real conversation about what it actually takes to create something that feels values aligned. His conversations are direct, compassionate, unfiltered, and practical, with room for both the emotional reality of entrepreneurship and the concrete decisions that shape a sustainable business.

New episodes drop every Wednesday and feature honest conversations with neurodivergent entrepreneurs, creators, therapists, business owners, and leaders. Together, Patrick and his guests explore entrepreneurship, identity, mental health, chronic health,
creativity, leadership, systems, money mindset, visibility, community, sustainable growth, and the behind-the-scenes reality of creating work that matters.

Build your dream business. Protect your capacity. Work with your brain instead of against it.
