In this episode of The Pediatric Pharmacist Review, we explore the phenomenon of seasonal affective disorder (SAD) and its relevance to children, adolescents, and families. Our guest, Tim Horton, is a seasoned psychiatric nurse‑practitioner (APRN, CNP) and founder of PeopleFirst Clinic in Woodbury, Minnesota, where he specializes in holistic, medication‑management and therapy‑integrated care for youth and adults. With his unique background in pediatric mental health, patient‑centered approaches, and collaborative provider work, Tim brings deep insight into how biological and environmental factors converge in seasonal depression—and what practical actions caregivers and clinicians can take to mitigate its impact.
