Your competent? doctor is responsible for eliminating 3 of these by having EXACT 100% RECOVERY PROTOCOLS! Depression, social isolation and physical inactivity
Eliminating these 14 risk factors may prevent nearly half of dementia cases
Key takeaways:
- The Lancet Commission identified high cholesterol and vision loss as new risk factors for dementia.
- The commission outlined 13 recommendations for individuals and governments to prevent dementia.
PHILADELPHIA — Tackling 14 risk factors for dementia beginning in childhood could prevent or delay nearly half of cases worldwide, according to a report from the Lancet Commission presented at the Alzheimer's Association International Conference.
These include two risk factors — high cholesterol and vision loss —
newly identified by the commission on dementia prevention, intervention
and care.
An estimated 57 million people were living with dementia in 2019, Gill Livingston, MD, a professor of psychiatry at University College London, and colleagues wrote in the report. This number is expected to increase to 153 million by 2050, highlighting the need for risk reduction strategies.
The new report is an update to the commission’s 2020 report. Members of the commission adopted a triangulation framework that prioritized systematic reviews and meta-analyses. They also conducted new meta-analyses when necessary.
The researchers said their review supports the 12 potentially modifiable risk factors that were identified in the 2020 report: air pollution (RR = 1.1; 95% CI, 1.1-1.1); depression (RR = 2.2; 95% CI, 1.7-3); diabetes (RR = 1.7; 95% CI, 1.6-1.8); excessive alcohol use (RR = 1.2; 95% CI, 1-1.5); hearing loss (RR = 1.4; 95% CI, 1-1.9); hypertension (RR = 1.2; 95% CI, 1.1-1.4); lower education level (RR = 1.6; 95% CI, 1.3-2); obesity (RR = 1.3; 95% CI, 1-1.7); physical inactivity (RR = 1.2; 95% CI, 1.2-1.3); smoking (RR = 1.3; 95% CI, 1.2-1.4); social isolation (RR = 1.6; 95% CI, 1.3-1.8); and traumatic brain injury (RR = 1.7; 95% CI, 1.4-1.9).
The evidence also supports the addition of high LDL cholesterol (RR = 1.3; 95% CI, 1.3-1.4) and vision loss (RR = 1.5; 95% CI, 1.4-1.6).
If these 14 risk factors are eliminated, “nearly half of dementias could theoretically be prevented,” Livingston and colleagues wrote.
This has important implications for physicians, particularly family physicians, Livingston told Healio. She noted that diabetes, excessive alcohol use, hearing impairment, high LDL, hypertension, obesity, vision loss and smoking account for about one-quarter of all dementias.
“If we add depression, traumatic brain injury and physical inactivity, which family physicians also advise on, then it is a third of dementias,” she said. “Their active vigilance and advice potentially make a huge difference.”
Based on their findings, the researchers outlined 13 recommendations for individuals and governments to prevent dementia:
- ensure children have access to good-quality education and encourage individuals in midlife to participate in “cognitively stimulating activities;”
- reduce harmful noise exposure and make hearing aids accessible to those with hearing impairment;
- treat depression;
- promote helmets and other head protection during contact sports and when riding bicycles;
- encourage exercise;
- reduce smoking through education and by implementing policies that aim to control the cost of cigarettes;
- prevent or reduce high blood pressure;
- diagnose and treat high LDL;
- maintain a healthy weight and treat obesity early;
- reduce excessive alcohol use through price control and raising awareness about the risks of overconsumption;
- reduce social isolation by encouraging activities and living with other people, prioritizing an “age-friendly and supportive community, environments and housing”;
- ensure access to vision loss screening and treatment; and
- decrease air pollution exposure.
“Although addressing risk factors at an early stage of life is desirable, there is also benefit from tackling risk throughout life; it is never too early or too late to reduce dementia risk,” Livingston and colleagues wrote.
