Who benefits from brain training, and why?
Irvine, Calif., June 21, 2022 — If you are skilled at playing puzzles on your smartphone or tablet, what does it say about how fast you learn new puzzles, or more broadly, how well can you focus in school or at work? In the language of psychologists, does “near transfer” predict “far transfer”? A team of psychologists from the University of California, Irvine and the University of California, Riverside reports in Nature Human Behavior that people who show near transfer are more likely to show far transfer.

“Older adults might be representing events in different ways, and transitions might be picked up differently than, say, a 20-year-old,” said Zachariah Reagh, assistant professor of psychological and brain sciences in Arts & Sciences. Reagh looked at fMRI images to study memory differences in different age groups.

Could High Blood Pressure at Night Have an Effect on Your Brain?
Most people’s blood pressure goes down during the night, which doctors call “dipping.” But for some people, especially those with high blood pressure, their nighttime pressure stays the same or even goes up, called “reverse dipping.” A new study shows that people with high blood pressure and reverse dipping may be more likely to have small areas in the brain that appear damaged from vascular disease and associated memory problems. The study is published in the April 15, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
