Purdue News: Researchers Examining Link Between Sleep and Alzheimer’s

April 11, 2025

Researchers at Purdue University are looking at the connection between sleep and Alzheimer’s disease. “Ultimately, we know there is an early onset type that influences people as long as young as 30, but it can affect people from the 40s through the 60s age group. Then we have a later onset group that tends to have the first signs happening at 65 and up. It is the most common type of dementia affecting more than 6 million Americans,” said A.J Schwichtenberg, associate professor of Human Development and Family Science and director of Purdue University’s Sleep and Developmental Studies Laboratory.

How mothers adapt to the metabolic demands of nursing

April 10, 2025

Nursing poses major metabolic demands on mothers, to which they respond by eating more and saving energy to sustain milk production. There are significant hormonal changes during lactation, but how they lead to metabolic adaptations in nursing mothers remained unclear. Medical researchers uncovered a mechanism that connects prolactin, estrogen, the brain and metabolic adaptations during lactation.

Even under stress, male-female pairs had each other's backs

April 7, 2025

When faced with a potential threat, mice often freeze in place. Moreover, when two animals are together, they typically freeze at the same time, matching each other's periods of immobility. In a new study, researchers found that coordination during fear looks different in males and females.

A new analysis of a vaccination program in Wales found that the shingles vaccine appeared to lower new dementia diagnoses by 20% — more than any other known intervention.

Blood test shows promise for early detection of dementia

March 11, 2025

For people with a certain sleep disorder, a simple blood test could help predict the development of dementia years before symptoms appear, a new study indicates. Idiopathic REM sleep behavior disorder (iRBD) causes people to physically act out their dreams while sleeping. The disorder is also associated with a very high risk of Parkinson's disease and a related condition called Dementia with Lewy Bodies. This is a form of dementia that often causes memory and cognitive loss, as well as vivid visual hallucinations and movement difficulties similar to Parkinson's.

Levels of select vitamins and minerals in pregnancy may be linked to lower midlife BP risk

March 6, 2025

Higher levels of the minerals copper and manganese in pregnant women were associated with lower blood pressure and a reduced risk of developing high blood pressure decades later, according to a long-term study.

Links between metabolism and aggressive breast cancer

March 6, 2025

More than 120 million Americans suffer from diabetes or pre-diabetes. Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer, and TNBC patients with obesity-driven diabetes often have worse outcomes. A new study helps explain why this happens and suggests a potential way to improve treatment for these patients.

New STI impacts 1 in 3 women: Landmark study reveals men are the missing link

March 6, 2025

A landmark study reveals that bacterial vaginosis (BV), a condition affecting nearly a third of women worldwide and causing infertility, premature births and newborn deaths, is in fact an STI, paving the way for a revolution in how it is treated.

Findings may advance understanding of infertility in mothers

March 5, 2025

Oxytocin, a hormone already known for its role in childbirth, milk release, and mother-infant bonding, may have a newfound purpose in mammalian reproduction. In times of maternal stress, the hormone can delay an embryo's development for days to weeks after conception, a new study in rodents shows. According to the authors, the findings about so-called 'diapause' may offer new insights into pregnancy and fertility issues faced by humans.
