New Short Film Highlights Climate Change's Hidden Effects on Brain Health

A compelling new short film emphasizes the urgent importance of understanding and addressing the impact of climate change on neurological health. Developed by the FutureNeuro Research Ireland Center and the Royal College of Surgeons in Ireland (RCSI) in partnership with the International League Against Epilepsy (ILAE) Climate Change Commission, the documentary aims to raise awareness about the threats rising global temperatures pose to individuals with neurological conditions such as epilepsy, multiple sclerosis, and dementia.

The film features insights from prominent experts including Dr. Stephen Blenkinsop and Professor David Henshall from Newcastle University and RCSI, respectively. It vividly shares the personal stories of people living with neurological disorders, illustrating how climate-related factors like heatwaves directly and indirectly affect their well-being.

Research indicates that climate change causes long-term shifts in global temperatures that impact human health worldwide. Over three billion people are affected by neurological conditions, and rising temperatures can increase seizure frequency, worsen symptoms, and impair brain function especially for temperature-sensitive diseases such as Dravet syndrome.

Experts like Dr. Blenkinsop highlight the undeniable influence of human activity on climate change, emphasizing its wide-ranging health effects. Professor Sanjay Sisodiya underscores the vulnerability of the brain to temperature variations, especially in individuals with existing neurological disturbances.

Current research using advanced imaging and AI models aims to monitor brain temperature fluctuations and predict at-risk populations. These efforts could lead to targeted interventions that mitigate heat-related neurological risks.

Organizations such as ILAE are spearheading initiatives to promote sustainable research practices, advocate policy reforms, and integrate climate considerations into neurological healthcare. Additionally, green laboratory practices are being implemented to reduce environmental impact.

The film also sheds light on the daily struggles faced by those with neurological conditions during extreme weather events. For example, Emma Campbell describes how heatwaves force her family into self-imposed isolation to protect her daughter with epilepsy, who faces increased risks during hot temperatures.

Regional and global vulnerabilities are rising, with climate change threatening medication stability, disrupting healthcare access, and spreading climate-sensitive diseases that can trigger neurological episodes.

This initiative underscores the interconnectedness of climate health and neurological well-being. Raising awareness, fostering policy change, and advancing research are crucial steps to ensure vulnerable populations are protected as the climate crisis deepens.
