AB  - Background. Preliminary evidence has highlighted a likely association between severe COVID-19 and persistent cognitive deficits. Further research is required to confirm this association, determine whethercognitive deficits relate to clinical features from the acute phase or to mental health status at the point of assessment, and quantify rate of recovery.Methods. 46 individuals who received critical care for COVID-19 at Addenbrooke’s hospital (16 mechanically ventilated) underwent detailed computerised cognitive assessment alongside scales measuring anxiety, depression and post-traumatic stress disorder under supervised conditions at a mean follow up of 6.0 (+ 2.1) months following acute illness. Patient and matched control (N=460) performances were transformed into standard deviation from expected scores, accounting for age and demographic factors using an N=66,008 normative datasets. Global accuracy and response time composites were calculated (G_SScore & G_RT). Linear modelling predicted composite score deficitsfrom acute severity, mental-health status at assessment, and time from hospital admission. The pattern of deficits across tasks was qualitatively compared with normal age-related decline, and early-stage dementia.Findings. COVID-19 survivors were less accurate (G_SScore=-0.53SDs) and slower (G_RT=+0.89SDs) than expected given the matched controls. Acute illness, but not chronic mental health, significantly predicted cognitive deviation from expected scores (G_SScore (p=0.0037) and G_RT (p=0.0366)). The most prominent task associations with COVID-19 were for higher cognition and processing speed, which was qualitatively distinct from the profiles of normal ageing and dementia. A trend towards reduced deficits with time from illness (r~=0.15) did not reach statistical significance.Interpretation. Cognitive deficits after severe COVID-19 relate most strongly to acute illness severity, persist long into the chronic phase, and recover slowly if at all
