A new study looking at sleep-disordered breathing (SDB) and markers for Alzheimer's disease (AD) risk in cerebrospinal fluid (CSF) and neuroimaging adds to the growing body of research linking the two. But this latest study also poses an interesting question: Could AD in its "preclinical

The use of genome-wide analysis (GWA), where the entirety of an individual's DNA is examined to look for the genomic mutations or variants which can cause health problems is a massively useful technology for diagnosing disease. However, it can also pose major ethical problems if

Brain power in older people at risk for vascular dementia seems to improve more from a Mediterranean diet with added mixed nuts or extra virgin olive oil than from a low-fat diet that is typically followed to prevent heart attack and stroke, according to

Using data from the National Institutes of Health (Heart, Lung, and Blood Institute)-funded Wisconsin Sleep Cohort Study, which has been following approximately 1,500 people since 1988, researchers

Optimal treatment of sleep apnea in patients with prediabetes improves blood sugar (glucose) levels and thus can reduce cardiometabolic risk, according to a study presented at the American Thoracic Society International Conference May 17-22, 2013 Philadelphia, Pennsylvania...

Expert systems estimate drug uptake in humans (bioavailability) more precisely than animal experiments In drug discovery today new drugs are tested on animals, such as rats, dogs and monkeys, to determine whether they are effective and possess sufficient oral bioavailability in these animals. Up to

Emergency physicians are key decisionmakers for nearly half of all hospital admissions, highlighting a critical role they can play in reducing health care costs, according to a new report from the RAND Corporation. Hospital admissions from the ER increased by 17 percent over seven years,
