“Diets rich in omega-3 fatty acids have been shown to decrease the risk of Alzheimer’s disease. A growing number of studies have also demonstrated the benefits of omega-3 supplementation in adults with dementia.”

“The study involved 33 older adults (average age, 78 years). Participants walked on a treadmill for 30 minutes a day, four times a week, for 12 weeks and underwent tests before and after the intervention to assess their physical and cognitive performance.”

“Olfactory system dysfunction may be due to decreased neurogenesis in the olfactory regions of the brains. In this way, changes in smell may signal decreased neurogenesis in other areas of the brain, which may indicate cognitive decline and Alzheimer’s disease progression.”

“Approximately 70 percent of all dementia cases are due to Alzheimer’s disease. Previous research has demonstrated that the incidence of dementia is influenced by non-modifiable risk factors, such as increasing age, ethnicity, and the presence of a genetic variant known as APOE4.”

“The authors of a recent report investigated the relationship between blood levels of pro-BDNF and memory loss. The effects of Alzheimer’s disease on the brain can be observed 10 to15 years before the onset of dementia, which presents the opportunity for early detection.”

“Parkinson's disease typically manifests later in life (past the age of 50 years) and is characterized by tremors and a shuffling gait. It is the second most common neurodegenerative disease after Alzheimer's disease.”

“Previous research demonstrates the ability of spermidine supplementation to restore memory performance in fruit flies; however, the effects of spermidine supplementation on memory performance in humans are unknown. The authors recruited 30 adults (aged 60 to 80 years) with subjective cognitive decline, a condition associated with objective cognitive decline and Alzheimer’s disease.”

“Nearly 50 million people worldwide live with Alzheimer’s disease or another form of dementia — a number projected to triple in the coming decades. However, a recent study suggests the number could be even higher, as much as 40 percent more than previous estimates.”

“A study from 2024 concluded that among all modifiable risk factors for Alzheimer's disease, moderate-to-vigorous physical activity was the single best predictor of future risk, second only to age overall.”
