An FDA-approved medication for treating enlarged prostate and high blood pressure, may also have potential to prevent or delay Alzheimer's disease, according to a new study by researchers at University of Iowa Health Care.

Every breath you take does more than deliver oxygen – it helps organize activity throughout the brain. University of Iowa neuroscientists have shown, for the first time, that the rhythm of breathing synchronizes widespread brain activity in humans whether they are awake, asleep, or even breathing via a mechanical ventilator. This synchronization suggests that breathing serves as a fundamental organizing signal for widespread human brain networks. Led by Brian Dlouhy, MD, UI associate professor of neurosurgery, and published in Nature Communications, this study is the largest direct human intracranial study of breathing and brain activity, with recordings from more than 1,200 brain sites.
