Hot, spicy & dangerous

Chili lovers might increase dementia risk

Think twice before adding that extra kick of chili sauce or chopped jalapeno to your meal. New research involving the University of South Australia shows a spicy diet could be linked to dementia. A 15-year study of 4582 Chinese adults aged over 55 found evidence of faster cognitive decline in those who consistently ate more than 50 grams of chili a day. Memory decline was even more significant if…

Spatial cognition and neurodegeneration

When the compass fails

Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation – a complex interaction of various cells in the brain – gives us answers to these questions. In November 2018, around 70 experts in Magdeburg discussed changes in this navigation system induced by age and illness at the ‘Interdisciplinary Symposium on Spatial Cognition in Aging and…

Will education save you from dementia? Don't count on it

Until now, neurologists were largely convinced that having a higher level of education would build some kind of protective barrier against neurodegenerative diseases like Alzheimer's. But a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the online issue of Neurology, the medical journal of the American Academy…

Sleep deprivation accelerates Alzheimer’s brain damage

Poor sleep has long been linked with Alzheimer’s disease, but researchers have understood little about how sleep disruptions drive the disease. Now, studying mice and people, researchers at Washington University School of Medicine in St. Louis have found that sleep deprivation increases levels of the key Alzheimer’s protein tau. And, in follow-up studies in the mice, the research team has…

Alzheimer's: key to early prediction in the blood

Alzheimer's disease is often marked by a creeping progression: Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded. Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research (HIH) and the University Hospital Tübingen now show that a protein found in the blood can be used…

Robot helps with early screening for Alzheimer’s patients

Alzheimer’s is the most common form of dementia. The US Centers for Disease Control and Prevention reports as many as five million Americans had the disease in 2013. They estimate that by 2050, nearly 14 million will have it. Age is the best known risk factor and memory loss is at the forefront of symptoms. Researchers of the Michigan Technological University investigate how technology can…

When less is more: Gene switch for healthy aging found

Aging is a major risk factor for physical frailty and the development of age-related diseases such as cancer, cardiovascular diseases, type II diabetes and Alzheimer's disease. Numerous studies have already shown that a calorie-restricted diet can significantly delay age-related conditions in several organisms like flies, worms, fish and mice, and that it even improves fitness at old age. But who…
