The latest episode of Brain Talks, recorded live at Brain Innovation Days 2025, examines how environmental exposures shape brain health across the lifespan. Host Sam Pauly is joined by Geert Dom (European Psychiatric Association), Bart Depreitere (University Hospitals Leuven, EANS), and Silke Matura (Goethe University Hospital, ECNP), to discuss the critical role of the exposome in brain development and disease risk.
The episode explores why early childhood adversity could account for 70% of adult mental health service needs, how ultra-processed foods increase depression risk by over 30% and accelerate cognitive decline by up to 10 years, and why simple lifestyle interventions like 9,000 daily steps can reduce dementia risk by 50%.
Key themes include the urgent challenges facing rapidly urbanising populations, with 86% of people expected to live in cities by 2050, the long-term brain health impacts of nutrition from maternal diet through to older adulthood, the hidden consequences of repetitive head impacts in sports, and the critical implementation gap between research evidence and policy action.
Tune in to discover how environmental factors influence brain health and why creating healthier environments is essential for current and future generations.
