New groundbreaking research has shed light on crucial health factors that could drastically decrease the likelihood of developing dementia. The 2024 Lancet Commission on dementia prevention, intervention, and care unveiled a significant discovery that addressing two specific issues could prevent or delay nearly half of all dementia cases.
Untreated Vision Loss and High Cholesterol: Culprits for Dementia Risk
A recent study by CBC pinpointed untreated vision loss and high cholesterol as key contributors to the risk of developing dementia. These additions join a list of 14 ‘potentially modifiable’ risk factors for dementia, which also include lower education levels, hearing impairment, high blood pressure, smoking, obesity, depression, physical inactivity, diabetes, excessive alcohol consumption, traumatic brain injury, air pollution, and social isolation.
Lifestyle Changes for Dementia Prevention
Dr. Eric B. Larson, a prominent researcher from the University of Washington School of Medicine and a co-author of the study, emphasized the critical importance of addressing these risk factors. He highlighted the significance of reducing high LDL cholesterol levels in midlife to lower dementia risk. Additionally, research spearheaded by ophthalmologist Dr. Cecilia Lee revealed that individuals who underwent cataract surgery had a lower likelihood of developing dementia compared to those who did not undergo the procedure.
The study underscored how cognitive and physical development throughout a person’s life can profoundly impact their dementia risk. It also indicated that efforts to reduce vascular damage, such as addressing smoking and high blood pressure, have contributed to a decline in dementia rates among older adults.
Global Perspectives on Dementia Prevention
Dr. Larson emphasized the inclusive nature of the latest Lancet Commission report, encompassing insights from experts in low- and middle-income countries. By targeting the 14 modifiable risk factors identified, individuals could potentially slash their risk of dementia by up to 45% over their lifetime. The report’s overarching message encourages an ambitious approach to dementia prevention.
In conclusion, the groundbreaking research serves as a beacon of hope, offering valuable insights into mitigating the risk of dementia by addressing vision loss and high cholesterol. By adopting preventive measures and fostering global collaboration, a significant reduction in dementia cases could be within reach.
