Age Is a Greater Influence on Small Saccades Than Target Size in Normal Subjects on the Horizontal Video Head Impulse Test
Conclusion: While this study suggests that target size may have a statistically significant impact on the vHIT saccade profile of normal subjects, age has a greater influence on the incidence and size of small vHIT saccades. Introduction The video head impulse test (vHIT) is a quantitative adaptation of the clinical head impulse test (1), and enables functional assessment of the high-frequency angular vestibulo-ocular reflex (VOR) in all three planes of head rotation (2, 3). Lightweight goggles worn by the subject detect head movement using an accelerometer and gyroscope, and a high frame rate video camera tracks eye...

How to stay healthy and happy through the decades
Successful aging can be the norm, says UCLA psychology professor Alan Castel in his new book, “Better with Age: The Psychology of Successful Aging” (Oxford University Press). Castel sees many inspiring role models of aging. French Impressionist Claude Monet, he notes, began his beloved water lily paintings at age 73.Castel cites hundreds of research studies, including his own, combined with personal accounts from older Americans, including Maya Angelou, Warren Buffett, John Wooden, Bob Newhart, Frank Gehry, David Letterman, Jack LaLanne, Jared Diamond, Kareem Abdul-Jabbar, John Glenn and Vin Scully.Castel notes that ar...

High-dose painkiller heart risk: small but significant
Conclusion This large review adds to, and expands on, the current evidence on the risks of vascular disease and gastrointestinal complications for different NSAIDs. It largely concentrates on trials of high doses of NSAIDs that can only be prescribed by a doctor. It is unclear from this study whether there is any risk from taking lower doses available over the counter. While most experts advise that low-dose NSAIDs, taken occasionally, are safe for most people, an accompanying editorial points out that there are still “large gaps” in evidence on the risks with lower doses of NSAIDs. While the risk to individuals is sma...
