Resting-State Functional Connectivity and Cognitive Performance in Long COVID: A Randomized Controlled Trial

Cognitive impairment is a prevalent, disabling manifestation of Long COVID, but whether cognitive rehabilitation alters neural network organization is unknown. We examined whether a 12-week cognitive rehabilitation intervention modified resting-state connectivity within the central-executive (CEN), default-mode (DMN), and salience (SN) networks, and whether connectivity changes associated with cognitive performance. Participants were adults with prior SARS-CoV-2 infection, persistent Long COVID symptoms ([≥]3 months), and objectively confirmed mild-to-moderate cognitive impairment. Of 58 pa
