Around a third of first year university students have or develop moderate to severe anxiety and/or depression, suggests the first study of its kind, published in the open access journal BMJ Open.

A human stroke drug, fast-tracked by the Food and Drug Administration and soon entering Phase 3 clinical trials, shows intriguing signs that it might also be a safe and powerful defense against Alzheimer’s and other forms of dementia. A new study published Tuesday in the Journal of Experimental Medicine showed the drug, 3K3A-APC, protected mice from injury to the brain’s white matter -- the second leading cause of dementia in humans. Such injuries occur when tiny clots block the flow of blood perfusing the brain’s white matter. Over time, these mini-strokes multiply and lead to cognitive decline.

A good night’s sleep plays an essential role in regulating brain health by removing the waste material and toxins that accumulate. Although many things can disturb sleep, one of the most common causes is snoring or other breathing issues that cause obstructive sleep apnea. A team of researchers from Center for BrainHealth® at The University of Texas at Dallas and Texas A&M University sought to understand the relationship between breathing rate during sleep and cognitive function, and how a snoring intervention affects brain health.

New Cornell University research uses mathematical modeling to show that type of thinking can have the opposite effect, resulting in the election of politicians who do not represent the preferences of the electorate as a whole.
