Alzheimer

Doug Whitney, a US mechanic carrying a genetic mutation that typically triggers early-onset Alzheimer’s disease, has reached his late 70s without symptoms. Researchers link his protection to decades of intense heat exposure in ship engine rooms. The case bolsters evidence that heat therapy may safeguard the brain against the condition.

Researchers at Cold Spring Harbor Laboratory have found that blocking the protein PTP1B improves memory and boosts plaque clearance in mouse models of Alzheimer's disease. The discovery links the protein to brain immune function and metabolic risks like diabetes and obesity. The team aims to develop inhibitors for potential human treatments.

Rice University scientists say they have created the first complete, label-free molecular atlas of an Alzheimer’s brain in an animal model, combining hyperspectral Raman imaging with machine learning to map chemical changes that appear unevenly across brain regions and extend beyond amyloid plaques.

New research from the University of Southern California suggests that subtle declines in brain blood flow and oxygen delivery may be early indicators of Alzheimer's disease. The study, published in Alzheimer's and Dementia, used noninvasive scans to connect vascular health with amyloid plaques and hippocampal shrinkage. These findings highlight the role of brain circulation in the disease process beyond traditional markers like amyloid and tau.

Researchers at the University of California, Irvine report that a machine-learning system called SIGNET can infer cause-and-effect links between genes in human brain tissue, revealing extensive rewiring of gene regulation—especially in excitatory neurons—in Alzheimer’s disease.

Researchers at Harvard University have identified what may be a network of lymphatic-like vessels inside the brain that could help remove waste fluid. The finding, made while studying Alzheimer's disease in mice, raises possibilities for understanding neurodegenerative conditions. If confirmed, it could shift how scientists view brain function and diseases like Alzheimer's.
