IFS and Autism with Sarah Bergenfield - Part 1

Autism functions as a difference in perception driven by a brain that struggles to update its predictive models, leading to an overweighting of sensory information and a heightened need for predictability. Sarah Bergenfield, a somatic psychologist and IFS practitioner, explains that this neurological reality causes the nervous system to remain in a state of chronic dysregulation, manifesting as the diagnostic criteria found in the DSM. Unlike neurotypical brains, the autistic system relies on stimming—rhythmic, repetitive movements—to anchor itself in the present and maintain a connection between top-down and bottom-up processing. Effective therapeutic support requires shifting from a deficit-based model to one that prioritizes sensory-friendly environments and psychoeducation, allowing clients to regulate their nervous systems and access self-energy. This approach validates the autistic experience by addressing underlying neurological needs rather than pathologizing behavioral differences.
