#Alzheimer's disease

A growing body of research suggests that the shingles vaccine does more than prevent a painful rash — it may significantly reduce the risk of dementia, including Alzheimer's disease, and even slow biological aging. The latest studies add to evidence that has been accumulating for years.

Researchers have found that Chlamydia pneumoniae, a widespread bacterium known for causing respiratory infections, can invade the brain and retina where it persists for years, triggering inflammation and amyloid-beta accumulation linked to Alzheimer's disease. The discovery opens new avenues for early detection through retinal imaging and potential antibiotic treatments.

Penn State scientists discover that a nanoscale lattice under the neuron membrane acts as a gatekeeper controlling amyloid-beta accumulation.
