A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a sharply higher dementia risk. Every additional 10 years of brain aging raised that risk by nearly 40%.

-------------------------------------------------TITLE: Researchers find evidence connecting a specific blood protein to brain tissue loss
Higher levels of a blood protein called growth differentiation factor 15 during midlife were associated with approximately twice the rate of dementia over the following twenty years. This protein is released by cells during aging, inflammation, and other forms of biological stress. The research, published in Science Advances, provides evidence linking this protein to future cognitive decline.
Previous research identified the protein as a possible early warning sign for dementia. However, scientists were uncertain whether it merely reflected poor health or actually contributed to damaging brain processes. To find out, researchers investigated whether blood levels of this protein predicted different forms of dementia. They also examined whether it was connected to brain changes, inherited risk, and immune activity.
Led by Cassandra O. Blew at the US National Institutes of Health, the team combined evidence from six large studies that tracked participants over time. The principal midlife analysis included 11,595 American adults with an average age of fifty-seven. These participants were followed for about twenty years. The scientists also analyzed data from older American adults, British participants, and Icelandic adults, with average ages ranging from sixty to seventy-six.
The researchers measured the protein in blood samples and examined subsequent diagnoses of all forms of dementia, including Alzheimer’s disease and vascular dementia. The statistical models accounted for factors like age, sex, kidney function, smoking, obesity, diabetes, and genetic susceptibility. Results revealed that in the midlife American sample, each doubling of the protein’s levels was associated with a 55 percent greater risk of developing dementia.
Among participants with protein levels in the top half of the group, 7.5 percent developed dementia over twenty years, compared with 3.9 percent of those in the bottom half. A similar pattern emerged in the older American group over a seven-year period. In that older group, 18.7 percent of individuals with high levels developed dementia, compared to 9.5 percent of those with lower levels.
The relationship was stronger for vascular dementia than for Alzheimer’s disease. Vascular dementia develops through reduced blood flow and damage to the brain’s blood vessels, while Alzheimer’s is associated with abnormal protein buildups. In the British sample, each doubling of the protein was associated with a 101 percent higher vascular dementia risk but only a 20 percent higher Alzheimer’s risk. The Icelandic group produced similar estimates, showing a 106 percent higher risk for vascular dementia compared with a 24 percent increase for Alzheimer’s.
Brain scans provided matching evidence. Higher levels of the protein were associated with smaller brain volumes, thinner brain tissue, and greater damage to white matter, which is the network of nerve fibers connecting different brain regions. The elevated protein also predicted increased odds of small strokes and microscopic brain bleeds. The findings suggest the protein relates more strongly to blood vessel damage, general brain tissue loss, and inflammation rather than the specific protein pathways of Alzheimer’s disease.
Genetic analyses provided evidence suggesting the protein might play a direct role in causing brain changes. To explore this, the team conducted an experiment using macrophages, which are immune cells that engulf and destroy cellular debris. The scientists exposed macrophages from six adults to the growth differentiation factor 15 protein. This exposure altered immune and energy-related pathways in the cells, such as reducing antiviral signaling and disrupting the removal of free heme, an iron-rich molecule that can be toxic when released from red blood cells.
The authors concluded that their findings support the role of this circulating protein as an early warning sign, particularly for vascular dementia and brain inflammation. They noted that the results also help identify the biological mechanisms by which the protein might drive dementia risk.
A few limitations restrict the study’s conclusions. The blood protein added only modest predictive information for dementia risk beyond a person’s age. The research design also cannot conclusively establish that the protein causes the disease. Finally, the association between the protein and dementia was not statistically significant in a smaller Japanese group of 340 people, suggesting further research is needed across different populations.

-------------------------------------------------TITLE: Higher optimism is associated with a lower risk of dementia
URL: https://www.psypost.org/higher-optimism-is-associated-with-a-lower-risk-of-dementia/
An analysis of Health and Retirement Study data found that higher optimism was associated with a somewhat lower risk of developing dementia over a study period of up to 14 years. The association remained even after the study authors accounted for health behaviors, controlled for possible reverse causation (the possibility that the early stages of dementia reduce optimism), and excluded individuals with the poorest mental health. The paper was published in the Journal of the American Geriatrics Society.
Optimism is the general tendency to expect favorable outcomes and believe that difficulties can be managed or overcome. It involves positive expectations about the future rather than simply feeling cheerful in the present.
Studies show that optimistic people are more likely to use active coping strategies, persist toward goals, and seek help when needed. Higher optimism is associated with better psychological well-being and lower levels of depression, anxiety, and perceived stress. It has also been linked to healthier behaviors, including greater physical activity, better diet, and stronger adherence to medical advice.
Some studies associate optimism with better cardiovascular health, stronger immune functioning, and a lower risk of premature death. These health benefits may partly arise because optimistic people cope more effectively with stress and maintain stronger social relationships. However, optimism does not guarantee good health, and many associations may also reflect personality, socioeconomic circumstances, or existing health differences.
Säde Stenlund, a researcher at the Harvard T.H. Chan School of Public Health, and colleagues noted that many previous studies have already linked higher optimism to better cognitive health, including some longitudinal studies. However, they pointed out that these studies usually have relatively shorter follow-up periods that do not fully account for the possibility of reverse causation between optimism and cognitive health.
The researchers analyzed data from the Health and Retirement Study with the aim of exploring the longitudinal association between optimism and the risk of developing dementia over a longer period. The Health and Retirement Study is an ongoing, nationally representative cohort study in the U.S. that began in 1992 and has followed men and women aged 50 years and older through biennial in-person interviews, telephone, and mailed questionnaires.
For this analysis, study authors used data from participants who completed cognitive assessments and provided data in in-person or telephone interviews at the age of 70 or older. This information was needed for a dementia assessment algorithm to determine whether participants suffered from dementia. Optimism was measured through self-reports via the Life Orientation Test-Revised Scale.
In total, the analysis used data from 9,071 individuals who were dementia-free when enrolled in the study. Their average age at that time was 74 years. On average, they were followed for 6.7 years, with a maximum follow-up of 14 years. About 57% of participants were women.
Results showed that 3,027 participants developed dementia over the course of the study. Participants with higher optimism were less likely to develop dementia. More specifically, for each one standard deviation increase in optimism, the risk of developing dementia over the course of the study was 15% lower after taking into account age, sex, race, ethnicity, education, chronic health conditions, and probable depression.
Interestingly, adding health behaviors (like physical activity and smoking) did not qualitatively change the findings. The findings also held when study authors controlled for possible reverse causation by excluding individuals who developed dementia within the first two years of follow-up.
“Higher optimism was associated with a lower incidence of dementia,” the study authors concluded. “These findings suggest a potential value of optimism in supporting healthy aging, which could be considered in future research on dementia prevention initiatives.”
The study contributes to the scientific knowledge about dementia risk and protective factors. However, study authors note that a number of potentially eligible participants were excluded from analyses due to missing data. These individuals tended to be slightly younger, more often non-Hispanic White, had somewhat higher education, and were generally healthier. This could affect the generalizability of findings somewhat. Because the study was observational, the possibility of unmeasured confounding variables remains.
The paper, “The Bright Side of Life: Optimism and Risk of Dementia,” was authored by Säde Stenlund, Hayami K. Koga, Peter James, Justin Farmer, Colleen B. McGrath, Francine Grodstein, and Laura D. Kubzansky.

> Most adults sit for about 9 to 10 hours each day. Earlier studies have linked long, uninterrupted sitting with cardiovascular disease, type 2 diabetes, and depression. Sitting has also been associated with dementia.
This is the first study to separate mentally passive sitting from mentally active sitting when examining dementia risk. ...
Mentally active sedentary behavior was linked to a lower risk of developing dementia among adults in middle age and older adulthood.
Spending more time in mentally active sedentary behavior was associated with a significant reduction in dementia risk, even when levels of passive sedentary behavior, light physical activity, and moderate to vigorous physical activity were maintained.
