UrduA new study lends further weight to the idea that vision problems and dementia are linked. In a sample of nearly 3,000 older adults who took vision tests and cognitive tests during home visits, the risk of dementia was much higher among those with eyesight problems – including those who weren’t able to see well even when they were wearing their usual eyeglasses or contact lenses.

Opting for Olive Oil Could Boost Brain Health
A new study suggests that incorporating olive oil into your diet could help reduce the risk of dying from dementia.
Running Throughout Middle Age Keeps ‘Old’ Adult-born Neurons ‘Wired’
A new study provides novel insight into the benefits of exercise, which should motivate adults to keep moving throughout their lifetime, especially during middle age. Long-term exercise profoundly benefits the aging brain and may prevent aging-related memory function decline by increasing the survival and modifying the network of the adult-born neurons born during early adulthood, and thereby facilitating their participation in cognitive processes.
Children use the same brain network as adults for tough problems
Children as young as 4 years old show evidence of a network in the brain found in adults that tackles difficult cognitive problems, a new study found.The multiple demand network helps people focus their attention, juggle several things in memory at the same time, and solve difficult problems like those involving math.And while this network is not fully developed in kids, the study showed it operated similarly as it does in adults, said Zeynep Saygin, senior author of the study and assistant professor of psychology at The Ohio State University.
Study Provides First Evidence of a Relationship between a Bird’s Gut and its Brain
A study of the relationships between cognition and the gut microbiome of captive zebra finches showed that their gut microbiome characteristics were related to performance on a cognitive assay where they learned a novel foraging technique. Researchers also identified potentially critical bacteria that were relatively more abundant in birds that performed better on this assay. This correlation provides some of the first evidence of a relationship between a bird’s gut microbiome and its brain.
Depression symptoms linked to reduced cognitive control in people with autism
Adolescents and young adults with autism spectrum disorder (ASD) and those with typical development show similar proactive cognitive control. However, symptoms of depression in individuals with autism were linked to less proactive control, a UC Davis study found.
