“Dementia: Among 87,577 adults, average daytime exposure above 1,000 lux was associated with 16% lower dementia risk, while at least 42 minutes per day above 5,000 lux was associated with 17% lower risk. Nighttime light was not significantly associated with dementia in that analysis.”

“The decline of BDNF function during aging may contribute to deficits in learning and memory and the progression of dementia and Alzheimer's disease. Some have estimated that one-third of dementia cases are attributable to modifiable risk factors, including aerobic exercise.”

“Each year, participants underwent cognitive assessments to determine whether they had developed mild cognitive impairment or dementia. Over nearly seven years of follow-up, 545 participants developed dementia, and 695 developed mild cognitive impairment.”

“Higher brain concentrations of vitamin D were associated with 25 to 33 percent lower odds of having dementia or mild cognitive impairment at the last assessment before their death.”

“People with dementia often experience visual problems, which range in severity from difficulty seeing contrasts or colors to impaired understanding of spatial relationships. These visual problems typically manifest early in dementia, indicating that early vision testing may help identify those at risk.”

“A new study shows that eating a Mediterranean-style diet reduces the risk of dementia. Older adults with higher adherence to a Mediterranean-style diet were 23 percent less likely to develop dementia than those with lower adherence.”

“A new study shows that having low bone density may increase a person's risk for cerebral small vessel disease – a driver of dementia. People with the lowest bone density in their upper femur were twice as likely to develop dementia over a ten-year period than those with the highest bone density.”

“This was true even after considering other factors that increase dementia risk. Researchers analyzed the findings of five large studies investigating the effects of reducing blood pressure in older adults (average age, 69 years) on the risk of dementia.”

“Six years later, investigators reviewed the participants' electronic medical records for the incidence of physician‐diagnosed dementia. They found that a lack of physical exercise was associated with an increased risk of developing dementia in a dose-dependent manner.”

“Alzheimer's disease and dementia are age-related disorders characterized by memory loss, cognitive decline, and behavioral changes. As many as 55 million people worldwide have dementia, a figure expected to triple in the next three decades.”
