Scientists may have overcome a major roadblock in the development of Alzheimer's therapies by creating a new technology to observe—in the back of the eye—progression of the disease before the onset of symptoms. Clinical trials are to start in July to test the technology in humans according to a paper recently published in Investigative Ophthalmology & Visual Science. https://medicalxpress.com/news/2016-07-alzheimer-symptoms-eye-technology.html Alzheimer's disease & dementia Mon, 11 Jul 2016 15:02:49 EDT news387468158 There is good news for frequent public speakers. New research shows that individuals have the ability to quickly and accurately identify a crowd's general emotion as focused or distracted, suggesting that we can trust our first impression of a crowd's mood.
