Blended antioxidant supplement improves cognition and memory in aged mice
Cell damage from oxidative stress is a major underlying cause of age-related cognitive and muscle strength decline. Antioxidants can reduce oxidative stress and prevent age-related health decline. A new study has found that mice administered with a blended antioxidant supplement show significant improvements in spatial cognition, short-term memory, and mitigated age-related muscle decline. The study […]
Smartphone Tests Detect Frontotemporal Dementia
Cognitive tests administered through a smartphone mobile application (app) accurately and reliably detected frontotemporal lobar degeneration (FTLD), also known as frontotemporal dementia (FTD), an observational study showed. The smartphone tests had moderate to excellent internal consistency and test-retest reliability (intraclass correlation coefficient range of 0.77-0.95), according to Adam Staffaroni, PhD, of the University of California […]
Glucose Changes in Type 1 Diabetes May Affect Thinking Speed
In type 1 diabetes, glucose fluctuations were linked with cognitive processing speed, but not sustained attention, researchers reported. According to data collected every 5 minutes from continuous glucose monitors, large fluctuations in glucose were associated with slower processing speed as measured by digital symptom matching reaction time, Zoë Hawks, PhD, of McLean Hospital in Belmont, […]
Memory, Cognitive Symptoms Linked to Sleep Apnea
Memory and cognitive symptoms were tied to self-reported sleep apnea, cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) showed. In a survey of more than 4,200 U.S. adults, those who reported sleep apnea symptoms had greater odds of also reporting memory or cognitive symptoms (OR 1.88, 95% CI 1.48-2.37, P<0.001), said Dominique […]
Even With Alzheimer’s Pathology, Healthy Lifestyles May Preserve Cognition
Cognitive function was better for older adults with healthy lifestyles even if they had Alzheimer’s or other dementia-related pathologies, autopsy data showed. A 1-point increase in a healthy lifestyle score was associated with better cognitive performance proximate to death (β=0.216, P<0.001), reported Klodian Dhana, MD, PhD, of Rush University Medical Center in Chicago, and co-authors. […]
Cognitive Slowing May Be a Hallmark of Long COVID
Pronounced cognitive slowing distinguished people with long COVID from others, a cross-sectional study showed. On a 30-second task measuring simple reaction time, moderate-to-severe cognitive slowing was evident among long COVID patients compared with age-matched healthy individuals who had previous symptomatic SARS-CoV-2 infection and recovered, reported Sijia Zhao, PhD, at the University of Oxford in England, […]
Polycystic Ovary Syndrome Tied to Lower Midlife Cognitive Test Scores
Polycystic ovary syndrome (PCOS) was linked with lower cognitive test scores in middle age, a cohort study suggested. After 30 years of follow-up, women who were diagnosed as having PCOS in young adulthood performed lower on a composite of five cognitive function tests (ß coefficient for mean z scores difference -0.190, 95% CI -0.327 to […]
Following a Mediterranean diet reduces the risk of cognitive decline in older people
Old people who follow a Mediterranean diet are at a lower risk of cognitive decline, according to a study published in the journal Molecular Nutrition and Food Research. The study provides new evidence for a better understanding of the biological mechanisms related to the impact of the diet on cognitive health in the ageing population. […]
This Is Why You Forget Some Things And Remember Others
Westend61 via Getty Images Remembering to do something is actually a complex cognitive process. This morning, heading out the door to take my 9-year-old daughter to school, I patted my pockets to confirm “phone-keys-wallet.” This is a little ritual intended to keep me from having to run back for any of these essential items, or, […]
Post-COVID Cognitive Deficits Linked With Clotting Proteins
Two distinct blood biomarker profiles predicted cognitive deficits 6 and 12 months after COVID-19, prospective U.K. data showed. Both biomarker profiles featured proteins involved in coagulation, reported Maxime Taquet, PhD, of the University of Oxford in England, and co-authors in Nature Medicine. Among 1,800 patients hospitalized for COVID-19 during the first wave of the pandemic, […]
