While scores for verbal reasoning and matrix reasoning have decreased, scores for spatial reasoning have improved, researchers report.
A new study found that having both diabetes and complete tooth loss accelerates cognitive decline in older adults. The study emphasizes the importance of regular dental visits, adherence to diabetes treatment, and cognitive screenings for those with both conditions.
For those with multiple sclerosis, following a Mediterranean diet may help lower the risk of developing cognitive, memory, and thinking problems.
Retired football players who experienced concussions during their careers performed worse on cognitive tests than non-players. The findings add to the growing body of evidence that suggests head injuries experienced by football players accelerate cognitive aging. Researchers say the results underlie the importance of tracking concussion symptoms in football players as opposed to concussion diagnosis.
In adults, levels of GDF11, a gene that is key to the regeneration of murine neural stem cells, are inversely related to depressive episodes. Administering the GDF11 proteins to aging mice reduced depressive states and improved cognition.
Women who experience gestational high blood pressure or preeclampsia during pregnancy are at greater risk of cognitive decline as they age.
Long COVID is linked to reduced oxygen uptake in the brain, a new study reports. Researchers say the finding is significant as a lack of sufficient oxygen supply may be one of the mechanisms that cause brain fog, cognitive problems, and an increased risk of depression and anxiety in long COVID patients.
Examining the cognitive abilities of the AI language model, GPT-3, researchers found the algorithm can keep up and compete with humans in some areas but falls behind in others due to a lack of real-world experience and interactions.
In babies born preterm, the cerebral cortex, a brain area associated with learning and cognition is often underdeveloped. In preterm babies fed larger quantities of breastmilk, the cerebral cortex resembled those of babies born full term. Researchers say breastfeeding could help to reduce learning and behavioral deficits associated with preterm birth.
Cognitive reserve measured through IQ predicted the steepness of cognitive decline in aging men, but not women.
An AI model of gene regulation in the brain identified thousands of mutations associated with neocortical development and the facilitation of mathematical abilities.
During periods of social isolation, astrocytes in the brain become hyperactive. This suppresses circuit formation and memory formation. Reversing astrocyte hyperactivity can help mitigate memory deficits associated with social isolation.
