Scientists just watched Alzheimer’s damage happen in real time

Scientists at Oregon State University have captured something researchers have long struggled to see: the real-time chemical interactions that help drive Alzheimer’s disease. By watching how metal ions—especially copper—trigger harmful protein clumping in the brain, the team uncovered a clearer picture of how the disease develops at a molecular level.

A new type of dementia is forcing doctors to rethink memory loss

Doctors are only just getting to grips with LATE – a newly recognised form of cognitive decline behind up to one in five dementia cases

When a parent or grandparent begins forgetting names, misplacing objects or repeating the same stories, the diagnosis most people expect is Alzheimer’s disease. For decades, Alzheimer’s has dominated public understanding of dementia, becoming almost shorthand for memory loss itself.

But that assumption is increasingly being challenged. Neurologists now know that a significant number of people with Alzheimer’s-like symptoms actually have a different condition altogether – one that most families, and even many doctors, have only recently heard of.

Risk of Alzheimer Dementia After High-Dose vs Standard-Dose Influenza Vaccination

Previous studies, including large cohort analyses comparing vaccinated and unvaccinated adults, suggest that routine immunizations such as inactivated influenza vaccines (IIVs) may reduce Alzheimer dementia (AD) risk. Whether AD risk differs after high-dose IIV (H-IIV) vs standard-dose IIV (S-IIV) remains unexamined. We hypothesized that AD risk would be lower among adults ≥65 years after H-IIV compared with S-IIV.
