As 2024 comes to a close, it is evident that this year will be recorded as Earth’s hottest year on record, surpassing the previous record set in 2023. With rising temperatures and more frequent heat waves, vulnerable populations, such as individuals living with neurodegenerative diseases, are at an increased risk of heat-related complications. Dr. Indu Subramanian, a researcher at UCLA Health, emphasizes the need for healthcare providers to address the unique challenges faced by these individuals in the face of escalating heat waves.
In a recent commentary published in JAMA Neurology, Dr. Subramanian underscores the importance of understanding the impact of heat waves on individuals with conditions like dementia and Parkinson’s disease. With worsening symptoms and potential side effects of medications, people with neurodegenerative diseases are more susceptible to heat-related illnesses. For example, individuals with Parkinson’s disease may experience difficulties in regulating body temperature, leading to dehydration, heat stroke, and fainting. Additionally, certain medications used to treat these conditions can inhibit the body’s natural cooling mechanisms, further increasing the risk of heat-related complications.
Studies have shown a significant increase in mortality and hospital admissions for individuals with Parkinson’s and Alzheimer’s diseases during periods of high temperatures. Factors such as access to green spaces near residences can also influence heat-related outcomes, with those living in areas with limited greenery facing a higher risk of heat-related mortality.
As the population ages, the number of individuals living with neurodegenerative diseases is expected to rise. It is crucial for healthcare providers to implement best practices and guidelines to protect these vulnerable populations from the adverse effects of heat waves. Telemedicine and proactive monitoring can play a key role in identifying high-risk individuals and providing timely interventions to prevent heat-related complications.
Dr. Subramanian emphasizes the need for early intervention and preventive measures to safeguard individuals with neurodegenerative diseases from the dangers of heat waves. By raising awareness and implementing targeted strategies, healthcare providers can make a significant impact in reducing heat-related morbidity and mortality among this population.
