Migraines linked to higher risk of dementia

Dementia is the most common neurological disease in older adults, whereas headaches, including migraines, are the most common neurological disorder across all ages. In a recent study in the International Journal of Geriatric Psychiatry that included 679 community-dwelling adults aged 65 years and older, migraines were a significant risk factor…

Finnish people’s unique genetic makeup offers clues to disease: Study of Finns, with their similar DNA, gives new hints to cardiovascular, metabolic disease risk

A new study harnessed the unique genetic history of the people of Finland to identify variations in DNA that might predispose certain individuals to disease, whether or not they are Finnish themselves. The study was conducted by researchers at Washington University School of Medicine in St. Louis, in collaboration with…

Scientists map toxic proteins linked to Alzheimer’s

A team of researchers from McMaster University has mapped at atomic resolution a toxic protein linked to Alzheimer’s disease, allowing them to better understand what is happening deep within the brain during the earliest stages of the disease. The findings, published on the front cover of the current edition of…

Sleep history predicts late-life Alzheimer’s pathology: Findings suggest novel, sleep-based diagnosis and treatment methods

Sleep patterns can predict the accumulation of Alzheimer’s pathology proteins later in life, according to a new study of older men and women published in JNeurosci. These findings could lead to new sleep-based early diagnosis and prevention measures in the treatment of Alzheimer’s disease. Alzheimer’s disease is associated with disrupted…

Understanding what makes Tennessee whiskey unique

The sugar maple tree yields autumn foliage, maple syrup and Tennessee whiskey. Wood from the tree is chopped into planks, stacked in piles and burned to form charcoal. Freshly distilled, un-aged whiskey is filtered over the charcoal in a mysterious, but necessary step known as the Lincoln County Process (LCP)….

Long-lived parents produce better quality offspring

Genetic manipulation that more than doubles lifespan also leads to better offspring — according to new collaborative research from the University of East Anglia and Uppsala University. Researchers studied a gene, known as DAF-2, which is associated with ageing in roundworms (Caenorhabditis elegans). They found that by reducing this gene’s…

What happens when sand fleas burrow in your skin?

Tungiasis, a tropical disease associated with poverty, is caused by the penetration of female sand fleas into a person’s skin, usually in their toes or feet. This week in PLOS Neglected Tropical Diseases, researchers report five cases of severe tungiasis to illustrate how the disease may develop into a life-threatening…
