Having multiple conditions that affect the heart are linked to a greater risk of dementia than having high genetic risk, according to a largescale new study co-led by the University of Oxford.

It’s often said that a little stress can be good for you. Now scientists have shown that the same may be true for cells, uncovering a newly-discovered mechanism that might help prevent the build-up of tangles of proteins commonly seen in dementia.

Enhanced Nerve Transmission Seen in Older Adults Who Remained Active

A Georgetown University Medical Center clinical trial investigating the cancer drug nilotinib in people with Alzheimer’s disease finds that it is safe and well-tolerated, and researchers say the drug should be tested in a larger study to further determine its safety and efficacy as a potential disease-modifying strategy.

Insights into how a gene that increases the risk of Alzheimer’s disease disrupts brain cells have been revealed by scientists.

Harnessing a probe used to image the brain in diagnosing Alzheimer’s disease and related forms of dementia, scientists at Dana-Farber Cancer Institute and Massachusetts General Hospital (MGH) have successfully cleared patient-derived brain cells of an abnormal protein associated with dementia and other neurogenerative disorders.  

For older adults, it may seem as though the die is already cast regarding their odds of developing dementia, but new research from the University of Pittsburgh has identified a dementia risk factor among older adults that should be modifiable even well into old age.

Only a small proportion of cases of dementia are thought to be inherited – the cause of the vast majority is unknown.
