DNA mutation
Alzheimer’s may increase DNA variants in brain neurons
Study finds that Alzheimer’s neurons accumulate more DNA variants than occur from aging alone. The pattern of the variants is linked to oxidative damage and problems with DNA repair processes.

Hydroxychloroquine lowers dementia risk in humans, improves molecular signs of Alzheimer’s in mouse and cell models
Hydroxychloroquine is linked to lower dementia risk in older individuals and can reduce molecular signs of Alzheimer’s in mouse and cell models, according to an NIA study.

Links found between viruses and neurodegenerative diseases
A research team led by NIH’s Center for Alzheimer’s and Related Dementias found 45 associations between viruses and neurodegenerative diseases with the strongest link between viral encephalitis and Alzheimer’s.

Study of green tea and other molecules uncovers new therapeutic strategy for Alzheimer’s
Researchers have observed how a molecule found in green tea dismantles tau tangles found in Alzheimer’s disease, leading to discovery of additional molecules that can untangle tau and are potential Alzheimer’s treatments.
Beta-amyloid plaques
Estimates of amyloid onset may predict Alzheimer’s progression
Determining how long beta-amyloid plaques have been building up in a person’s brain may help predict the course of their Alzheimer’s disease.
Influenza B virus particles isolated from a patient sample and propagated in cell culture.
Could a viral illness increase chances of developing Alzheimer’s or other neurodegenerative disease?
Some viral illnesses may increase a person’s chances of later developing Alzheimer’s disease or another neurodegenerative disorder. Though a causal link cannot be confirmed, an NIH study found significant associations.
