URL: https://www.sciencedaily.com/releases/2026/09/260930225459.htm
Scientists have linked a gut bacterial compound called ImP to greater Alzheimer’s risk, harmful brain protein buildup, and faster cognitive decline. The finding raises the possibility that reducing ImP in the blood could one day help slow or prevent dementia.

URL: https://www.sciencedaily.com/releases/2026/09/260923035930.htm
A large study tracking more than 95,000 people suggests that how you sleep may be linked to your risk of developing dozens of diseases. People who spent more time in REM sleep had lower risks of 83 conditions, including dementia, heart failure, and Parkinson’s disease, while more deep sleep was associated with lower risks of conditions such as type 2 diabetes and major depression.

-------------------------------------------------TITLE: Daily variations in salivary cortisol may predict cognitive decline in older adults
An analysis of the Chicago Health and Aging Project data found that cortisol level variations may be used to predict cognitive decline in older adults. Longitudinally, individuals with medium to high cortisol intraday variability showed slower cognitive decline whereas individuals with the highest average cortisol levels tended to show faster cognitive decline. The paper was published in JAMA Network Open.
As people grow older, their mental functioning gradually worsens. This is called age-related cognitive decline. Changes are typically seen in memory, processing speed, attention, and executive functioning, although the extent of decline varies considerably between individuals. Chronic stress may contribute to this process by repeatedly activating the hypothalamic-pituitary-adrenal axis (the neural mechanism responsible for reactions to stress) and altering the regulation of the stress hormone cortisol.
Cortisol can influence brain regions that are especially important for memory and higher-order cognition, including the hippocampus and prefrontal cortex. Persistently elevated or dysregulated cortisol has therefore been investigated as a possible contributor to poorer cognitive functioning and greater risk of neurodegenerative disease.
Aside from cortisol, other systemic processes, such as inflammation, metabolic dysfunction, and vascular health, may also affect the course of cognitive aging. Because many of the factors shaping these processes are potentially modifiable, age-related cognitive decline is increasingly studied within the broader field of dementia prevention.
Study author Ted K. S. Ng and his colleagues explored daily variations in salivary cortisol in a large and racially diverse group of older adults over an 11-year follow-up period. They chose to test saliva because it specifically measures physiologically active “free” cortisol and avoids the acute stress response caused by needle pricks during blood draws. They examined the associations between these variations and participants’ cognition, Alzheimer’s disease occurrence, and cognitive decline over time.
The study used data from the Chicago Health and Aging Project (CHAP). CHAP is an established population-based longitudinal study of aging and Alzheimer’s disease among community-dwelling older adults on the South Side of Chicago in four Chicago neighborhoods with substantial proportions of Black and White older adults. CHAP data were collected in three-year cycles, starting in 1993, and with later data collection waves conducted up to 2012.
Data used in this analysis came from 3,895 participants who provided saliva samples for the study. To be included in the analysis, they needed to have provided saliva that allowed at least one valid cortisol level assessment. Participants’ average age was 77 years. Sixty-four percent of them were women, and 64 percent were Black. Eighty-three percent of these participants provided three valid saliva samples.
From the cortisol level data derived from saliva samples (cortisol levels from three collection time points), multiple indices of daily variations in hypothalamic-pituitary-adrenal axis (HPA axis) activity were created. The HPA axis is a hormone-regulating system linking the hypothalamus, pituitary gland, and adrenal glands that controls the body’s stress response, including cortisol secretion. Its activity level reflects how strongly the body’s stress-regulation system is operating. Daily variations in its activity can provide much more nuanced information.
The participants also completed in-home interviews at three-year intervals that assessed their cognitive functioning. Additionally, clinical evaluations of a smaller group of participants explored whether they were developing Alzheimer’s disease. This was done by a neurologist who was not informed about participants’ cognitive assessment scores.
The results showed that participants with middle to high intraday variability in cortisol levels—meaning how much their cortisol levels fluctuated over the course of a single day—had higher cognitive functioning at the start of the study and slower cognitive decline. Participants with the highest intraday variability in cortisol levels also tended to have better cognitive functioning at the start but did not show slower decline. Participants with the highest average cortisol levels tended to show faster cognitive decline compared to those with the lowest levels. Their cognitive function scores at the start of the study tended to be the lowest. People whose cortisol levels stayed relatively high across the day instead of dropping normally, and people who showed the largest overall change in cortisol across the day, had lower cognitive scores at the start of the study than those with the lowest values on these patterns.
These associations did not depend on the race of participants. However, Black participants tended to have lower cortisol levels, smaller daily change, and lower intraday variability in cortisol levels.
“In this cohort study of Black and White older adults, altered diurnal [daily] cortisol patterning was associated with faster cognitive decline but not short-term AD [Alzheimer’s disease] risk. These findings support salivary cortisol as a potential early biomarker of neurocognitive aging,” the study authors concluded.
The study sheds light on the utility of cortisol as a biomarker of cognitive health in older adults. However, the study did not assess the stress levels participants perceived, so it remains unknown how much the variations in cortisol levels reflect reactions to environmental stressors and how much they reflect intrinsic physiological differences or changes in the biochemistry of the body.
The paper, “Salivary Cortisol and Cognitive Decline and Alzheimer Disease in Older Adults,” was authored by Ted K. S. Ng, Todd Beck, Yashwanth Sudhini, Robert S. Wilson, Denis A. Evans, and Kumar B. Rajan.

-------------------------------------------------TITLE: How growing up in East Germany affected cognitive health in later life
URL: https://www.psypost.org/how-growing-up-in-east-germany-affected-cognitive-health-in-later-life/
Older adults who lived in socialist East Germany before the 1989 reunification show better cognitive health and slower mental decline today than their West German peers. This unexpected advantage seems linked to the former East German educational system, which featured longer compulsory schooling and widespread early childcare. The findings were recently published in the journal Research on Aging.
Following World War II, Germany was split into two distinct nations with opposing political and economic models. The German Democratic Republic in the East operated as a socialist state with a planned economy. The Federal Republic of Germany in the West developed as a capitalist, liberal democracy.
When the countries reunited in 1989, citizens merged into a single legal and economic system. This unique history provides researchers with a natural experiment to study how entirely different societal structures affect human development over a lifetime.
The contrast between East and West Germany represents a rare situation where culturally similar populations were separated by completely different modes of governance. The East German welfare state prioritized collective investments, aiming to build a highly productive workforce through extensive health and education services.
Previous research has consistently shown that East Germans suffered worse physical health and lower life expectancies compared to West Germans. These physical disparities are largely attributed to differences in health behaviors, economic development, and cardiovascular health.
Sociologist Ariane Bertogg at the University of Konstanz and gerontologist Jeffrey E. Stokes at the University of Massachusetts Boston wanted to see if these political systems left a similar footprint on the aging brain. They tested two competing ideas about cognitive aging.
One theory suggested West Germans would perform better on cognitive tests in later life because they enjoyed stronger economic growth, better nutrition, and more civil liberties. Another theory proposed that East Germans might have an advantage due to their state funded educational system.
East Germany mandated ten years of compulsory schooling, compared to eight or nine years in West Germany. The East also provided universal early childcare and a less socially divided school structure.
Educational exposure early in life is a primary driver of cognitive reserve. Cognitive reserve is the brain’s ability to build dense neural connections, which helps it compensate for age related damage and delay the onset of memory loss.
To find out which societal effect dominated, Bertogg and Stokes analyzed information from the Survey of Health, Ageing and Retirement in Europe. They looked at a large sample of 5,231 older adults who lived in either East or West Germany in 1989.
Participants were at least 50 years old during the study and were interviewed multiple times over an average of four years. The survey included four standard tests used to evaluate brain health and predict dementia.
Working memory was tested by asking participants to recall a list of ten words. Executive function, which involves planning and focusing attention, was measured by having people name as many animals as they could in a set time.
Orientation was scored based on whether participants correctly knew the current date and day of the week. Finally, numeracy was tested by having participants repeatedly subtract the number seven from one hundred.
The researchers used statistical models to map each person’s cognitive trajectory over time. They adjusted the results for factors like childhood health, household income, and overall educational attainment.
To account for early life conditions, the researchers utilized a special retrospective module of the survey. Participants provided detailed histories regarding their childhood health, their perceived math and language skills relative to peers, and the number of books in their childhood homes.
The data revealed that individuals who lived in East Germany before reunification performed better across all four cognitive tests. They also showed a slower rate of cognitive decline as they aged.
West German residents experienced a steady decline in immediate memory and verbal fluency over the course of the study. In contrast, East German residents maintained stable scores or even slightly improved in these areas.
East Germans also demonstrated less steep declines in their orientation and numerical abilities. The researchers noted that these advantages were especially pronounced in men.
The results present an unusual paradox in aging research. Usually, populations with poorer physical health and lower life expectancies also suffer from worse cognitive aging.
Despite East Germans having higher rates of cardiovascular disease and earlier mortality on average, their aging brains remained more resilient. This suggests that the early benefits of an egalitarian, intensive education system can offset some of the physical wear and tear associated with a lower standard of living.
Next, Bertogg and Stokes examined whether a person’s age at the time of reunification influenced their cognitive outcomes. They wanted to know if experiencing the transition during a specific life stage altered the trajectory of mental aging.
They found that the gap in memory and verbal fluency was widest between East and West Germans who were in their forties when the Berlin Wall fell. West Germans in this age group showed relative disadvantages compared to their Eastern counterparts.
For numeracy and orientation, the East German advantage was highest among those who experienced reunification in their twenties. The cognitive differences between the two populations were largely absent among people who were already nearing retirement age in 1989.
The researchers interpret this as evidence of critical periods in adult development. Entering the workforce during reunification may have helped young East Germans maximize the benefits of their schooling within the new, larger economy.
Conversely, West Germans navigating reunification in their forties may have faced intense economic competition and family stress. Mid adulthood is often a period of high financial responsibility, making individuals more vulnerable to the mental health impacts of economic shifts.
The two nations differed in many ways beyond education and economics. West Germans faced higher exposure to environmental toxins like lead from gasoline, simply because car ownership was much higher there.
Social and psychological experiences also varied wildly depending on the side of the border. West Germany fostered a more open civil society, while East Germany relied on secret police and informants, which negatively impacted social trust.
The dataset did not allow the researchers to measure the direct impact of these specific social and environmental stressors on brain health. Future investigations will need to look at similar differences across other post socialist and capitalist European countries to see if the pattern holds.
Future studies will also need to track clinical diagnoses of Alzheimer’s disease and other dementias, rather than just test scores. High performing individuals sometimes hit the maximum possible score on cognitive tests, which can mask early signs of decline.
Cognitive test performance does not capture the full reality of living with a neurodegenerative disease. Tracking actual medical records over time will clarify how these early life educational advantages translate into real world dementia prevention.
The study, “Is There a Cognitive Footprint of Political Systems? The Case of Separation and Reunification of East and West Germany and Its Association With Later Life Cognitive Health,” was authored by Ariane Bertogg and Jeffrey E. Stokes.

Aging and infectious diseases picked up years or decades ago are far more related than previously thought.
First was the Epstein-Barr virus and MS (multiple sclerosis):
"Longitudinal analysis reveals high prevalence of Epstein-Barr virus associated with multiple sclerosis", Bjornevik et al. 2022
https://www.science.org/doi/10.1126/science.abj8222Now the shingles vaccine and its effect on dementia:
"The effect of shingles vaccination at different stages of the dementia disease course", Xie et al. 2025
https://www.cell.com/cell/fulltext/S0092-8674(25)01256-5One wonders what else, and why aren't we vaccinating against many more illnesses, in this age of potentially rapid development of mRNA vaccines.

🧠✨ New research suggests **lithium deficiency may trigger Alzheimer’s disease**.
Tiny, natural levels of lithium appear to protect brain cells, while low levels increase risk. In mice, restoring lithium improved memory and slowed damage. Could this simple mineral become a powerful tool in preventing dementia?
Scientists may have found a surprising link between **lithium deficiency and Alzheimer’s disease**. Lithium is a natural mineral found in soil, water, and even in our bodies in tiny amounts. For decades, doctors have used higher doses of lithium to treat mood disorders like bipolar disease. But this new research suggests that *very small, natural levels of lithium* may play a role in keeping our brains healthy as we age.
The study, published in *Nature* in August 2025, looked at human brain tissue and animal models. Researchers noticed that when lithium levels in the brain dropped, the risk of Alzheimer’s disease went up. Alzheimer’s is a devastating condition that causes memory loss, confusion, and changes in thinking. It is marked by two key features: **amyloid plaques** (sticky protein clumps) and **tau tangles** (twisted fibers inside brain cells). Both were more common when lithium was low.
In mice, scientists tested what would happen if they gave back small amounts of lithium. The results were striking: memory improved, and the buildup of plaques and tangles slowed down. This suggests that lithium might act like a “brain protector,” helping neurons resist the damage that leads to Alzheimer’s. Importantly, the doses used were far lower than those given for psychiatric treatment—closer to what might naturally be found in food or water.
The research also looked at human populations. Areas with naturally higher lithium in drinking water seemed to have lower rates of dementia. While this doesn’t prove cause and effect, it adds weight to the idea that lithium deficiency could be a hidden risk factor for Alzheimer’s.
Why does this matter? Alzheimer’s affects millions of people worldwide, and current treatments only slow symptoms—they don’t stop or reverse the disease. If lithium supplementation at safe, low levels can help, it could open a new path for prevention. Imagine adding a trace mineral to diets or water supplies, much like fluoride was added to protect teeth. Of course, more studies are needed to confirm safety, dosage, and long-term effects in humans.The authors caution against rushing to take lithium supplements without medical guidance. Lithium at higher doses can be toxic, and the right balance is critical. But the findings give hope that something as simple as restoring a natural mineral could change the fight against Alzheimer’s.
**Key takeaways:**
Lithium is a mineral already present in our bodies in tiny amounts.
Low lithium levels may increase the risk of Alzheimer’s disease.
In mice, restoring lithium improved memory and reduced brain damage.
Human data suggest regions with more lithium in water have lower dementia rates.More research is needed, but this could be a low-cost, widely available way to protect brain health.
This discovery doesn’t mean lithium is a cure, but it shines a light on a new, promising direction. Sometimes, the smallest elements can make the biggest difference.

Red meat and processed red meat consumption linked to faster cognitive decline.🧠
A recent study tracked 133,000+ people and found that eating red meats, particularly processed red meats like bacon, sausages, and hot dogs is linked to a higher risk of dementia and faster cognitive decline.
⛔Some negative effects of red and processed red meats on the brain:
〰️Plaque buildup in blood vessels, increasing the risk of heart disease and stroke, both linked to dementia risk factors.
〰️High blood pressure, worsened by the excessive salt in processed meats, which further impacts brain health.
〰️Poor gut health – diets rich in plant-based fibre and fermented foods promote a healthy gut microbiome, which supports cognitive function. Conversely, diets high in ultra-processed foods (including processed meats) have been linked to a 44% higher risk of dementia.✨What can be done about this? 🌱✨
Switch to plant foods! Plant proteins like nuts, tofu, and beans can lower dementia risk by 19% and support long-term brain health. 🥜🌿
Your brain deserves the best—choose nutrient-dense, plant-based foods for a sharper mind. 🧠💡🌱
