A new culprit of cognitive decline in Alzheimer's disease

It has long been known that patients with Alzheimer's disease have abnormalities in the vast network of blood vessels in the brain. Some of these alterations may also contribute to age-related cognitive decline in people ...

Neuronal cytoskeletons involved in Alzheimer's disease

A researcher at the UPV/EHU participated in a study describing the loss of dynamics and subsequent impairment of the dendritic spines in Alzheimer's disease. Dendritic spines are the compartments of neurons responsible for ...

Neuroscience

Losing neurons is sometimes not all bad

Current thinking about Alzheimer's disease is that neuronal cell death in the brain is to blame for the cognitive havoc caused by the disease. But a new study suggests that neuronal death may actually be a protective reaction ...

Neuroscience

Detecting signs of neurodegeneration earlier and more accurately

Signs of neurodegenerative diseases, appearing years before the emergence of clinical manifestations, can be detected during the examination of medical samples by means of fluorescence microscopy by using new sensitive and ...

New information on the pathological mechanisms of Alzheimer's disease

Researchers at the University of Helsinki have discovered a mechanism by which harmful tau protein aggregates are transmitted between neurons. Alongside amyloid plaques, tau aggregates in the brain are a significant factor ...

Periodontal disease bacteria may kick-start Alzheimer's

Long-term exposure to periodontal disease bacteria causes inflammation and degeneration of brain neurons in mice that is similar to the effects of Alzheimer's disease in humans, according to a new study from researchers at ...
