Compared with controls, participants with PCC also had poorer dexterity and endurance on the NIHTB-MB, higher T scores for negative affect and perceived stress, but lower T scores for psychological well-being on the NIHTB-EB, as well as more pain symptoms and poorer mental and physical health on measures from the PROMIS. Greater brain activation predicted poorer scores on measures that were abnormal on the NIHTB-EB.Discussion Participants with PCC and neuropsychiatric symptoms demonstrated compensatory neural processes with greater usage of alternate brain regions, and reorganized networks, to maintain normal performance during WM tasks. BOLD-fMRI was sensitive for detecting brain abnormalities that correlated with various quantitative neuropsychiatric symptoms.AD=Alzheimer disease; BOLD-fMRI=blood oxygenation level–dependent fMRI; COVID-19=coronavirus disease 2019; DMN=default mode network; FDR=false discovery rate; ISP=Index of Social Position; NIHTB=NIH-Toolbox Battery; NIHTB-CB=NIHTB for Cognition Battery; NIHTB-EB=NIHTB for Emotion Battery; NIHTB-TB=NIHTB for Motor Function Battery; PCC=post-COVID condition; PCG=posterior cingulate gyrus; PROMIS=Patient-Reported Outcomes Measurement Information System; SARS-CoV-2=severe acute respiratory syndrome coronavirus 2; SFG=superior frontal gyrus; SPM=Statistical Parametric Mapping; TE=echo time; TI=inversion time; TR=repetition time; WM=working memory
