Lung disease may increase dementia risk

According to the study by researchers from the University of Minnesota’s School of Public Health in Minneapolis in collaboration with colleagues from other academic institutions in the United States, people who experience lung disease in midlife may have an increased risk of dementia later on. The study’s findings appear in the American Journal of Respiratory […]

Repeated interferon stimulation creates innate immune memory

The innate immune system may be able to be trained to react to viral infections more efficiently by repeated exposure to anti-viral signaling molecules. Mammalian cells seem to be able to memorize anti-viral stimulation at the level of DNA-packaging molecules, enabling faster and greater activation of anti-viral genes in subsequent stimulations, according to a study […]

Losing control of gene activity in Alzheimer’s disease

Pioneering research into the mechanisms controlling gene activity in the brain could hold the key to understanding Alzheimer’s disease and might help identify effective treatments in the future. An international research team led by scientists at the University of Exeter and the University of Essex have uncovered a link between indicators of gene activity and […]

Pre-eclampsia linked to an increased risk of dementia later in life

Pre-eclampsia is associated with an increased risk of later dementia, particularly vascular dementia, caused by reduced blood supply to the brain due to diseased blood vessels, finds a large study published by The BMJ today. The findings suggest that asking about a history of pre-eclampsia could help physicians to identify women who might benefit from […]

Modifiable dementia risk factor in older adults identified

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. The study, which draws on data collected from following hundreds […]

Hypothesis underpinning dementia research ‘flawed’

A hypothesis which has been the standard way of explaining how the body develops Alzheimer’s Disease for almost 30 years is flawed, according to a University of Manchester biologist. The amyloid cascade hypothesis argues that a series of stages, starting from the deposition of a starch-like protein called amyloid and ending with dementia, should be […]
