Alzheimer’s disease

Study shows that olive oil reduces risk of dementia mortality

A study in JAMA Network Open by researchers from Harvard T.H. Chan School of Public Health analyzed over 92,000 participants, finding that consuming at least 7 grams of olive oil daily could reduce dementia-related death risk by 28%. Replacing margarine and mayonnaise with olive oil also showed a reduced risk. The findings suggest that olive oil intake is beneficial for cognitive health, independent of overall diet quality.

Mediterranean diet and risk of dementia, Alzheimer’s disease?

Dementia and Alzheimer’s disease are global concerns as the population ages. The Mediterranean diet, characterized by whole grains, olive oil, fish, and moderate wine, has potential protective effects. Observational studies suggest that adherence to this diet reduces the risk of cognitive decline and Alzheimer’s disease. Mechanisms include antioxidants, improved vascular health, neuroprotection, and blood sugar regulation.

The three biggest risk factors for dementia

Researchers have identified modifiable factors like diabetes, air pollution, and alcohol as significantly increasing dementia and Alzheimer’s disease risks. Additionally, genetic factors affecting brain regions were noted, although they cannot be modified. The study emphasizes the complexity of these diseases and suggests healthy diet, active lifestyle, and social interaction as potential risk mitigators.

Study shows that Viagra may reduce risk of Alzheimer’s disease

Recent research supports the potential of Viagra (sildenafil) in reducing Alzheimer’s disease risk, revealing a 54% and 30% decreased incidence in two medical databases and a biologically plausible mechanism for protection against AD. However, further research is necessary, especially clinical trials, to confirm these findings and examine effects in women and the role of sexual activity.

BCG vaccine may be a weapon against Alzheimer’s disease

New research suggests the century-old BCG tuberculosis vaccine may also reduce Alzheimer’s disease risk. Originally developed against TB by Calmette and Guérin and proven highly effective, this vaccine now appears to have broad immunotherapeutic benefits. Clinical trials have demonstrated its potential in lowering Alzheimer’s and dementia risks, with studies indicating a 20-45% decrease in older patients with bladder cancer. Studies call for more research to validate these promising results, given Alzheimer’s growing prevalence and economic impact.

Being a dog owner might lower your risk of dementia

Owning a pet, especially a dog, may lower the risk of dementia and Alzheimer’s disease, according to two studies. The studies found that pet owners experienced less decline in verbal memory and fluency, which are early indicators of these diseases. This suggests that having a dog or other pets could have long-term cognitive benefits.

Chocolate does not prevent dementia and Alzheimer’s disease

Claims about chocolate enhancing heart health and cognitive function have been debunked. Clinical trials revealed that chocolate does not significantly prevent heart disease or improve cognition. Research conducted on over 2,000 adults found no beneficial effect of consuming cocoa on brain function, dementia, or Alzheimer’s disease, disappointing those who believed in its implied health benefits.
