TAY and the Developing Brain

This presentation will provide an overview of why adolescence (13-18) is a different time from the Emerging Adulthood / TAY experience (18-25) in terms of neurobiology. I will talk about how brain development impacts behavior during these years, why this particular time is of specific importance in the development of human behavior, as well as how trauma is speculated to impact individuals during this specific time. I will also provide some background around sociological impacts and the emergence of TAY as a current and distinct developmental age range worthy of a clinical approach that respects this unique stage of personal growth.

This session was originally presented as a live webinar in April 2020.
