Detecting Alzheimer’s disease in its earliest stages Australian scientists say they now are much closer to developing a screening test for the early detection of Alzheimer’s disease. The investigators have identified blood-based biological markers that are associated with the build-up of amyloid beta, a toxic protein in the brain. This plaque build-up develops years before symptoms appear and irreversible brain damage has occurred. “Early detection is critical, giving those at risk a much bette...
Wearing a contact lens at night may help restore age-related loss of near vision It may be possible to get rid of your reading glasses. Many older adults have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses. Now, a newly emerging technique called hyperopic orthokeratology (OK) may provide an alternative for restoring near vision without the need for glasses. Researchers have just completed a small study showing that wearing OK contact lenses overnight can...
New magnetic approach to treating heartburn It may be possible to replace your daily stomach medicine with a new magnetic device. It is called the LINX system and is composed of a series of titanium beads, each with a magnetic core. The beads are connected to form a ring shape and then implanted at the lower esophageal sphincter (LES), a circular band of muscle that closes the last few centimeters of the esophagus. The LES prevents the backward flow of stomach contents. This new medical device...
