Writing in the May 2, 2023 issue of the Journal of Alzheimer’s Disease, a team of researchers, led by scientists at University of California San Diego, further elaborate on how exposure to ambient air pollution, such as car exhaust and power plant emissions, is associated with a measurably greater risk of developing dementia over time.

Depressive symptoms and the absence of a stable partner can accelerate the progression of Alzheimer's disease in people who carry a genetic mutation. In addition, adequate treatment and controls in people with thyroid problems help delay depressive symptoms, progression to dementia, and death. These findings were reached by a team of researchers from the Universidad de Antioquia, Colombia, Universidad Nacional de Colombia, and Hamburg-Eppendorf University Medical Center, Germany, in a population with the "paisa mutation" or presenilin 1, E280A mutation carriers, for early-onset Alzheimer's disease.

A self-administered screening tool, developed by Cleveland Clinic researchers, can effectively and efficiently assess cognition issues in older adults. A new study found that the simple test taken on a tablet computer before an annual physical is conducive to use in a primary care setting for detecting mild cognitive impairment, early Alzheimer’s disease, and other related dementias. Results were published in Journal of Alzheimer’s Disease.

A new study shows that sleep medications increase the risk of dementia in whites. But the type and quantity of the medication may be factors in explaining the higher risk. It follows previous work that shows Blacks have a higher likelihood than whites of developing Alzheimer’s, the most common type of dementia, and that they have different risk factors and disease manifestation.
