Dementia

A recent study shows that combining magnetic brain scans with computer models can safely measure how dementia medications affect living human brains. This approach could replace invasive tests and speed up the development of new treatments for Alzheimer's disease.

A person’s combined physical and mental strength can predict their risk of developing memory problems later in life. New research suggests that a lower baseline of these everyday abilities increases the chance of future mild cognitive impairment.

New research demonstrates that preclinical cognitive decline may be identifiable through subtle language shifts. An analysis of Terry Pratchett's literature revealed significant decreases in adjective diversity nearly ten years prior to his formal dementia diagnosis.

While ultra-processed foods are often tied to health issues, a decade-long study suggests they do not speed up cognitive decline. Researchers found that overall diet quality plays a bigger role in maintaining memory and focus in older adults.

A recent study shows that accessible blood tests can accurately identify Alzheimer’s disease. When combined with standard cognitive assessments, these tools offer a reliable diagnostic approach for historically underrepresented populations in Latin America.

Researchers have developed a diagnostic panel that identifies cognitive decline by analyzing how blood proteins fold. This method accurately distinguishes between healthy aging and Alzheimer's disease, offering a fresh tool for early detection.

Older adults with exceptional memories continue to grow new brain cells. A recent study published in the journal Nature shows that this biological process nearly stops in people with Alzheimer's disease.

Researchers found vaccinated older adults had “younger” cells and less inflammation, though the study found no direct impact on blood markers of brain injury usually linked to dementia.

A new study reveals how a liver enzyme shores up the blood-brain barrier. Blocking a specific vessel protein replicated the cognitive benefits of exercise in aging mice and Alzheimer’s models.

New research reveals that repetitive strings of the amino acid serine can kill brain cells and accelerate the formation of toxic tau tangles associated with Alzheimer’s disease.

Two decades of data reveal that a specific type of brain training can delay dementia. Researchers found that older adults practicing visual processing speed, combined with follow-up sessions, had a significantly lower risk of diagnosis.

A new perspective published in Aging Clinical and Experimental Research suggests annual influenza vaccination could be a practical strategy to delay dementia. By reducing vascular inflammation, the flu shot may offer neurological protection beyond respiratory health.

Drinking two to three cups of caffeinated coffee or tea daily is linked to better brain health outcomes, according to a study tracking dietary habits over four decades.

A genetic screen of human neurons has identified a protein complex that tags toxic tau for destruction. The findings explain why some brain cells are resilient to Alzheimer’s disease while others succumb to degeneration.

Scientists have found a way to jumpstart the brain's waste-disposal system. By inhibiting a common metabolic enzyme, researchers enabled immune cells to devour Alzheimer’s plaque and improve cognitive function in mouse models.
