Researchers have found another way they might be able to identify Alzheimer’s disease at an early stage. A study in the journal JAMA Ophthalmology shows that an eye exam using already-available technology can reveal thinning in the retina of the eye… which is strongly correlated with early Alzheimer’s. Scientists used the technique to study 30 patients in their mid 70’s, none of whom had Alzheimer’s symptoms. Seventeen of them had thinning in the retina, indicating they may have early Alzheimer’s. Pet scans and other tests then indicated the eye test was right.
About 10 percent of people in the U.S. experience sleepless nights as a result of restless legs syndrome at one time or another. But now researchers say they’ve identified how the painful syndrome is triggered. A study in the journal Sleep Medicine shows that the area of the brain controlling leg movement seems to be in a constant state of readiness… as if the conscious brain is asking for the legs to move. Scientists hope the finding may lead to better ways to treat the condition.
And finally… wrinkles are usually a telltale sign of aging, but they might be a sign of something else as well–heart disease risk. A new study from French researchers suggests that deep forehead wrinkles—more than are typical for a person’s age—could be an easy, low-cost way to identify people with atherosclerosis. The study finds that over a 20-year period, people with deep wrinkles were nearly 10 times more likely to die of heart disease than people with a smooth forehead.
