          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.

          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.

          New Biomarker Links Brain Waste Clearance to Vascular Dementia

          A new study has identified a biomarker, DTI-ALPS, which connects glymphatic system dysfunction to vascular dementia. By analyzing over 3,750 participants, researchers found that lower DTI-ALPS scores correlated with worse executive function, highlighting the glymphatic system's role in clearing brain waste.

          New research highlights that some sedentary activities, like reading or crafting, are better for brain health than others, such as watching TV or gaming. A study of 397 older adults found that mentally stimulating and socially engaging activities support memory and thinking abilities, while passive screen time is linked to cognitive decline.

          Antipsychotics Worsen Behavior in Dementia

          A study of 500,000 Canadian nursing home residents found antipsychotic medications significantly worsened behaviors in patients, with nearly 68% experiencing increased issues. Antipsychotics are often prescribed "off-label" for dementia-related symptoms, despite serious side effects like tremors and cognitive decline. Researchers advocate for person-centered care, emphasizing non-drug therapies like music, art, and exercise to address behavioral issues.

          Study Links Muscle Loss to Alzheimer’s Risk

          New research shows that skeletal muscle loss, measured through temporalis muscle size on brain MRIs, is associated with a higher risk of developing Alzheimer’s disease. A study of 621 older adults found that those with smaller temporalis muscles were 60% more likely to develop dementia and experienced greater cognitive and brain volume decline over nearly six years.
