Stress, anxiety and depression during pregnancy may hinder toddler's cognitive development Posted: 29 Apr 2022 11:49 AM PDT Women's elevated anxiety, depression and stress during pregnancy altered key features of the fetal brain, which subsequently decreased their offspring's cognitive development at 18 months. These changes also increased internalizing and dysregulation behaviors, according to a new study. Researchers followed a cohort of 97 pregnant women and their babies. The findings further suggest that persistent psychological distress after the baby is born may influence the parent-child interaction and infant self-regulation. |
'Eye-catching' smartphone app could make it easy to screen for neurological disease at home Posted: 29 Apr 2022 11:49 AM PDT Researchers have developed a smartphone app that could allow people to screen for Alzheimer's disease, ADHD and other neurological diseases and disorders -- by recording closeups of their eye. The app uses a smartphone's built-in near-infrared camera and selfie camera to track how a person's pupil changes in size. These pupil measurements could be used to assess a person's cognitive condition. |

Living in areas with more greenery may boost cognitive function, study finds Posted: 27 Apr 2022 08:57 AM PDT New evidence links residential exposure to greenspace, such as green vegetation, as a potential population-level approach to improve processing speed and attention, and overall cognitive function. |
Controlling blood sugar may improve response to exercise training Posted: 25 Apr 2022 09:11 AM PDT Scientists sought to determine whether high blood glucose blunts the body's response to exercise and whether lowering it can restore the ability to improve aerobic capacity with training. The team's findings suggest that a combination of a glucose-lowering medication and exercise may work to improve exercise capacity in people with high blood sugar, or hyperglycemia. |
