Finding a Voice: Understanding Selective Mutism

Selective mutism is often misunderstood as shyness—but in reality, it’s a complex anxiety disorder that can deeply impact a child’s ability to communicate.In episode 70 of Autism in the Neuroverse, Alta sits down with licensed clinical social worker Heidi Applonie, a leading specialist in selective mutism. Drawing from both professional experience and her personal journey as a parent, Heidi shares what selective mutism really is, how it shows up across different environments, and why early understanding is so critical.They explore the connection between anxiety, the nervous system, and the “freeze” response that can make speaking feel physically impossible. Heidi also offers practical, research-backed strategies for parents, educators, and caregivers—highlighting what actually helps (and what can unintentionally make things harder).From real-life success stories to actionable tools like “brave talking,” this conversation is filled with hope, insight, and a clear message: communication is possible—with the right support.
