“Alcohol is another focus: a Finnish cohort followed for roughly 23 years found that drinking-related dementia risk differed by APOE status, although other cohorts have not found a significant interaction. These observational findings help frame questions about exposure and vulnerability.”

“Regular coffee consumption significantly lowers the risk of neurodegenerative diseases like Parkinson's and Alzheimer's—by about 34–37%. Moderate caffeine intake slows cognitive decline and enhances attention, reaction time, and memory, particularly valuable for individuals at elevated risk for dementia.”

“Observational studies have reported associations between nicotine or tobacco exposure and Parkinson's disease or dementia, but confounding and reverse causation prevent using those findings as a neuroprotective prescription.”

“The hippocampus supports learning and memory, making preservation of this region relevant to cognitive aging. A separate synthesis of prospective studies also linked higher omega-3 intake and blood levels with lower risks of cognitive decline or dementia.”

“EPA and DHA also produce specialized pro-resolving mediators such as resolvins, protectins, and maresins. These mechanisms support biological plausibility; they do not by themselves prove prevention of dementia, cancer, or aging.”

“A systematic review links these mechanisms with cognitive dysfunction and Alzheimer-related pathology, while a meta-analysis of 15 cohort studies found higher risk of cognitive impairment or dementia among people with sleep-disordered breathing.”

“Observational cohorts Across large prospective cohorts, higher blueberry, berry, or anthocyanin intake is generally associated with slower cognitive decline and lower dementia risk over time.”

“Brain derived neurotrophic factor (BDNF) is a growth factor associated with decreased risk of dementia and improved cognitive function in humans. While BDNF promotes brain cell growth plasticity, its precursor form, called proBDNF, has the opposite effect, promoting cell death.”

“A subset analysis in the oldest patients (older than 70 years) revealed significant improvements in clinical dementia and Alzheimer's disease assessments. Some evidence suggests that metal chelators may be beneficial for the treatment of Alzheimer’s disease.”

“In a second study, researchers looked at whether participants had suffered a stroke or been diagnosed with dementia due to Alzheimer's disease. Interestingly, there was no association between sugary beverage intake and stroke or dementia.”
