- Approximately 40% of the risk for cognitive decline is preventable through lifestyle changes and proactive measures.
- Nearly 7 million Americans are affected by Alzheimer's, with numbers expected to double in the coming decades. It's the sixth leading cause of death, costing the US around $800 billion annually.
- Not Inevitable: Cognitive decline is not an inevitable part of aging, as demonstrated by figures like Barbara Walters and Henry Kissinger, who remained mentally sharp well into their later years.
Part 2: Strategies That Work
- Exercise: Regular physical activity is associated with a 28% reduction in the likelihood of Alzheimer's. Dancing, in particular, has shown benefits due to its combination of physical and mental engagement.
- Sleep: Adequate sleep (around seven hours per night) is crucial, with poor sleep increasing the risk of Alzheimer's by 68%.
- Smoking: Smoking cessation is critical, as smoking is linked to 5% of dementia cases.
- Blood Pressure Control: Managing hypertension can greatly reduce the risk of cognitive decline
- Obesity and Diabetes: Both conditions are associated with an increased risk of dementia.
- Sauna Use: Regular sauna use correlates with a reduced risk of dementia, with benefits increasing with frequency of use and time/session.
- Hearing Loss: Treating hearing loss may lower the risk of cognitive decline by maintaining cognitive stimulation.
- Alcohol Consumption: Reducing alcohol intake can decrease the risk of cognitive impairment.
- Social Engagement: Maintaining strong social connections is associated with a reduced risk of dementia.
Part 3: Strategies That Don't Work
- Omega-3 Supplements: No substantial evidence supports their role in preventing cognitive decline.
- Brain-Focused Diets: Diets like the MIND diet have not shown significant benefits in reducing cognitive decline in clinical trials.
Part 4: Unclear or Emerging Strategies
- Probiotics, Viagra, and Multivitamins may have benefits.
- Brain Training Games: While they may improve specific skills, there is limited evidence that they prevent general cognitive decline. Newer approaches have some promising results
