The year 2024 is on track to become Earth’s hottest year on record, surpassing the previous record set in 2023. With rising global temperatures, people living with neurodegenerative diseases are particularly vulnerable to the increasing frequency and severity of heat waves. Dr. Indu Subramanian, a researcher at UCLA Health, emphasizes the need for healthcare providers to better understand and address the impacts of heat on these vulnerable individuals.
In a recent commentary published in JAMA Neurology, Dr. Subramanian highlights the importance of recognizing and mitigating the risks of heat-related complications for patients with diseases such as dementia and Parkinson’s disease. The symptoms and treatments associated with neurodegenerative diseases can be exacerbated by heat, leading to dehydration, heat stroke, and other serious health issues.
Heat has been shown to worsen symptoms of neurodegenerative diseases, such as Parkinson’s, by impacting the body’s ability to regulate temperature. Some medications used to treat these conditions can further inhibit the body’s natural cooling mechanisms, increasing the risk of heat-related complications. Studies have shown a significant increase in mortality and hospital admissions for patients with Parkinson’s and Alzheimer’s diseases during heatwaves.
Access to green spaces and social isolation also play a role in heat-related risks for older adults with neurodegenerative diseases. Lack of green space near residences can contribute to higher mortality rates during heatwaves, while social isolation can limit access to resources and early detection of heat-related issues.
To address these challenges, Dr. Subramanian suggests implementing best-practice guidelines for healthcare providers and institutions. Regular screening for social isolation, proactive monitoring of high-risk patients during heatwaves, and the use of telemedicine for remote check-ins are all strategies that can help protect vulnerable individuals. By taking proactive steps and providing resources to patients, healthcare providers can help prevent heat-related deaths in this at-risk population.
The commentary was co-authored by Dr. Ali Saad of the University of Colorado, Aurora, who has completed a Climate Change Fellowship. Dr. Subramanian’s expertise in integrative medicine underscores the importance of a holistic approach to addressing the intersection of climate change and neurodegenerative diseases.
As the global population ages and temperatures continue to rise, it is crucial to prioritize the health and safety of individuals living with neurodegenerative diseases. By raising awareness, implementing proactive strategies, and fostering collaboration between healthcare providers, policymakers, and communities, we can work towards a safer and more resilient future for all.
