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.

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).

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.

Brain Cell Genetics Shape Aging and Alzheimer’s Risk

Researchers have identified genetic variations in brain cells, particularly microglia and oligodendrocytes, that influence both aging and Alzheimer’s risk. These variations impact how cells function as they age, potentially priming some individuals for dementia.

Head Trauma May Reactivate Dormant Viruses, Increasing Alzheimer’s Risk

New research suggests that concussions and repetitive head trauma may reactivate dormant viruses like HSV-1 in the brain, potentially triggering neurodegenerative diseases such as Alzheimer’s. Using a brain tissue model, scientists observed that head trauma caused latent HSV-1 to awaken, leading to hallmark Alzheimer’s markers such as amyloid plaques, inflammation, and neuronal damage.

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.

Link Between Cold Sore Herpes Virus and Alzheimer’s Discovered

Researchers discovered a connection between Alzheimer’s disease and herpes simplex virus-1 (HSV-1), suggesting viral infections may contribute to neurodegeneration. The study found that tau protein, typically seen as harmful in Alzheimer’s, might initially protect the brain from the virus but later exacerbate damage.

Chronic Gut Virus May Play a Role in Alzheimer’s Development

Researchers have linked chronic intestinal infections caused by cytomegalovirus (HCMV) to a unique subtype of Alzheimer’s disease. The virus may travel from the gut to the brain via the vagus nerve, altering immune responses and contributing to hallmark Alzheimer’s changes like amyloid plaques and tau tangles. While HCMV infection is common and typically harmless, this study found that it may cause chronic brain inflammation in certain individuals.

Some Sedentary Activities Are Good For Brain Health

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.

Diets That Reduce Brain Iron May Delay Cognitive Decline

New research suggests that certain nutrients may lower iron buildup in the brain, a factor linked to cognitive decline in aging. Excess non-heme iron, which accumulates over time, contributes to oxidative stress and can impair memory and executive function.

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.

Herbicide Exposure Linked to Long-Term Brain Inflammation, Alzheimer’s

New research reveals that glyphosate, a widely used herbicide, can cause lasting brain inflammation and accelerate Alzheimer’s-like pathology in mice. Even short-term exposure resulted in persistent inflammatory markers and neurological damage, including anxiety-like behaviors and premature death. The study found that glyphosate’s metabolite, aminomethylphosphonic acid, accumulates in brain tissue, raising concerns about its long-term safety for humans.
