Dr. Kohlenberg and Dr. Rahman are both clinicians with expertise in neuropsychiatric illness in Phelan-McDermid syndrome. They discuss the first signs and symptoms, where to find treatment guidelines, how to connect your clinician with experts, and the difference between neuropsychiatric illness and regression. They discuss top research questions and progress. Kate points out where families can find key resources along the way.
