![]() Physical function is associated with important outcomes, yet there is often a lack of continuity in routine assessment. Further studies are needed to characterize the natural history of CI in this patient population and to test interventions aimed at preventing or slowing its progression. These deficits may be attributable to the HD treatment itself. There is a high prevalence of CI evident early after starting HD, with the largest deficits seen in reasoning and verbal processing. Fifty-five percent of HD patients had cognitive impairment in verbal skills, 43% in reasoning and 18% in short-term memory. The average scores for HD patients were consistently below the age and sex-matched controls. #CAMBRIDGE BRAIN SCIENCES PEAK BRAIN APP FULL#We used the validated Cambridge Brain Science (CBS) battery of web-based tests to evaluate cognition compared to age- and sex matched controls across three cognitive domains: verbal processing, reasoning and short-term memory.įorty-nine HD patients were included in this study 43 completed the full battery of tests. This was a cross-sectional study of a cohort of low dialysis vintage HD patients (<12 months). While cognitive impairment in the HD population is increasingly recognized, it is unclear how quickly it develops after starting HD. Cognitive performance is positively correlated with the global measure encompassing physical symptoms, but not the one that broadly described mental health, suggesting that the subjective experience of “long COVID” relates to physical symptoms and cognitive deficits, especially executive dysfunction.Ībnormalities in cognitive function are almost universal in patients receiving hemodialysis (HD) and are associated with worse quality of life, impaired decision making, increased healthcare utilization and mortality. Factor analysis of health- and COVID-related questionnaires reveals two clusters of symptoms: one that varies mostly with physical symptoms and illness severity, and one with mental health. Cognitive differences are even observed in participants that did not require hospitalisation. In this cross-sectional online study, 478 adult volunteers who self-reported a positive test for COVID-19 (M=30 days since most recent test) perform significantly worse than pre-pandemic norms on cognitive measures of processing speed, reasoning, verbal, and overall performance, but not short-term memory – suggesting domain-specific deficits. However, important questions about the cognitive impacts of COVID-19 remain unresolved. As COVID-19 cases exceed hundreds of millions globally, many survivors face cognitive challenges and prolonged symptoms. ![]()
