Dementia

Scientists have identified a biological tipping point in microglial behavior that may determine whether Alzheimer's pathology leads to dementia, offering new treatment targets.

Researchers developed a nasal spray that reversed brain aging and improved memory in test models by reducing inflammation and restoring cellular energy.

A routine blood test marker, the neutrophil to lymphocyte ratio, may predict a person's risk of developing Alzheimer's disease years before symptoms appear, suggesting immune cells could play a role in the disease's progression.
