THURSDAY, Feb. 29, 2024 (HealthDay News) -- Similar small cognitive deficits are seen for individuals who recovered from COVID-19 in whom symptoms had resolved in less than four weeks or at least 12 weeks, according to a study published in the Feb. 29 issue of the New England Journal of Medicine. <\/p>\n
Adam Hampshire, Ph.D., from Imperial College London, and colleagues estimated a global cognitive score across eight tasks in 112,964 participants who completed an online cognitive assessment. <\/p>\n
The researchers found that compared with individuals in the no-COVID-19 group who had not been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or had unconfirmed infection, participants who recovered from COVID-19 in whom symptoms had resolved in less than four weeks or at least 12 weeks had similar small deficits in global cognition (0.23 and 0.24 standard deviation [SD], respectively), while larger deficits were seen for those with unresolved persistent symptoms (0.42 SD). Participants who had SARS-CoV-2 infection during periods in which the original virus or the B.1.1.7 variant was predominant had larger deficits than those infected with later variants; deficits were also larger for those who had versus had not been hospitalized. These results were similar to those of propensity score-matched analyses. Memory, reasoning, and executive function tasks were associated with the largest deficit in comparison of the group with unresolved persistent symptoms versus the no-COVID-19 group. <\/p>\n
\"We found objectively measurable cognitive deficits that may persist for a year or more after COVID-19,\" the authors write. \"The implications of longer-term persistence of cognitive deficits and their clinical relevance remain unclear and warrant ongoing surveillance.\" <\/p>\n
