Changes in Sleep Patterns Could Predict Dementia Risk

A new study finds that women in their 80s who develop increasing daytime sleepiness over five years are twice as likely to develop dementia. Researchers tracked 733 women without cognitive impairment, using wrist devices to monitor sleep and circadian rhythms.

Long-Term NSAID Use Linked to Lower Dementia Risk

A new study finds that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a lower risk of developing dementia. Researchers followed 11,745 adults over 14.5 years and found that those who used NSAIDs long-term had a 12% reduced dementia risk.

Physical Activity Lowers Brain Disease Risk

A large study found that people who engage in moderate to vigorous physical activity are significantly less likely to develop dementia, stroke, anxiety, depression, and sleep disorders. Researchers analyzed data from over 73,000 individuals using wearable devices to track their activity levels, providing objective measurements of movement and sedentary behavior.

Low-Normal B12 Levels Linked to Slower Brain Processing

Even when within the normal range, lower levels of vitamin B12 may contribute to cognitive decline, according to a new study. Researchers found that older adults with lower biologically active B12 had slower cognitive processing and more white matter lesions, despite meeting current nutritional requirements.

Brain Bleeds Double Dementia Risk

Researchers have found that intracranial hemorrhages, or "brain bleeds," double the risk of developing dementia later in life. While ischemic strokes caused by blood clots have long been linked to cognitive decline, this study shows that hemorrhages also significantly increase dementia risk. Using Medicare data from nearly 15,000 patients, scientists observed a two-fold increase in dementia diagnosis within about 5.6 years after a brain bleed.

Oral Microbiome May Influence Cognitive Decline and Brain Health

The microbial ecosystems in our mouths may impact cognitive function as we age, with pathogenic bacteria linked to cognitive decline. Researchers found that beneficial bacteria, such as Neisseria, are associated with improved memory and attention, while harmful bacteria like Porphyromonas correlate with mild cognitive impairment.

REM Sleep Delays May Indicate Early Alzheimer’s

Delayed rapid eye movement (REM) sleep may be an early indicator of Alzheimer’s disease. Researchers found that participants with delayed REM sleep had higher levels of toxic proteins associated with Alzheimer’s and reduced levels of brain-derived neurotrophic factor (BDNF), which supports memory.

Antibiotics and Other Drugs May Reduce Dementia Risk

A study analyzing data from over 130 million individuals found that antibiotics, antivirals, vaccines, and anti-inflammatory medications are associated with a reduced risk of dementia. This supports the idea that infections and inflammation contribute to dementia and highlights the potential of repurposing existing drugs for prevention or treatment.

GLP-1 Drugs Offer Brain Benefits but May Pose Other Health Risks

A study analyzing data from over 2 million veterans found that GLP-1 receptor agonists, popular weight-loss drugs like Ozempic and Wegovy, provide significant neurological and behavioral health benefits, including reduced risks of addiction, Alzheimer’s, and dementia. However, they also pose risks for pancreatitis and kidney conditions, emphasizing the need for careful monitoring.

Processed Red Meat Linked to Higher Dementia Risk

A study of over 133,000 individuals found that consuming processed red meat daily increases dementia risk by up to 13%, while replacing it with alternatives like nuts, legumes, or fish may lower the risk by 20%. Higher processed meat intake was associated with accelerated cognitive aging and increased subjective cognitive decline (SCD).

Mapping the Link Between Personality and Cognitive Decline

A new study has identified three psychological profiles that influence brain health, cognitive decline, and dementia risk in aging adults. Profiles with high protective traits, like purpose and openness, show better cognition and brain integrity, while those with low protective traits or high negative traits face accelerated brain atrophy and mental health issues.

This shows the outline of people and brains.

Almost Half of Americans Over 55 Face Dementia Risk

New research finds that the lifetime risk of dementia after age 55 in Americans is 42%, significantly higher than previous estimates. Women face a higher risk (48%) than men (35%) due to their longer life expectancy. Risk factors include genetic predisposition, hypertension, diabetes, obesity, and limited physical activity.
