The Untold Overlap of Autism, ADHD, and Complex Trauma

When we think of autism, ADHD, or even trauma, we often place them in separate boxes, as distinct diagnoses with different treatment paths. But what if the reality is far more connected? What if complex trauma itself is a form of neurodivergence? What if masking, sensory overwhelm, and dissociation are not flaws to be fixed, but intelligent adaptations of a nervous system doing its best to survive?

In this episode of Trauma Rewired, we’re joined by Dr. Megan Anna Neff, clinical psychologist, author of Self-Care for Autistic People, and co-host of the Divergent Conversations podcast. Dr. Neff sits down with Elisabeth and Jennifer for a powerful, eye-opening conversation about the deep overlap between autism, ADHD, complex PTSD, and sensory processing challenges and why embracing this intersection is key to healing and self-acceptance.

Together, we explore how trauma shapes the neurodivergent brain, why so many autistic women remain undiagnosed, and how dissociation and emotional shutdowns are often rooted in sensory overload. Dr. Neff also shares her personal journey of late-diagnosed autism and ADHD, and the life-changing reframes that helped her make sense of her body and nervous system.

This episode is not about pathologizing difference. It’s about honoring the body's wisdom, reframing trauma as adaptation, and understanding why a nervous system-first approach to healing is essential.

If you’ve struggled with masking, emotional dysregulation, chronic dissociation, or a lifetime of “being too much” or “not enough,” this conversation offers a compassionate, grounded lens to view your experience, and new possibilities for healing.

Topics discussed in this episode:
● Masking: the hidden labor of social camouflage
● Why complex trauma is a form of neurodivergence
● Sensory trauma, sensory overload, and emotional shutdowns
