Through an online platform created for the study, adults who self-reported cognitive impairment more than 3 months after receiving a COVID-19 diagnosis will be enlisted and their cognitive status will be assessed using a commercially available test. After determining their level of general cognitive dysfunction, those who qualify and meet the inclusion criteria will be invited to use a customized computerized cognitive training (CCT) program at home and to complete as many daily training sessions as they would want over the course of eight weeks. The sessions will consist of gamified cognitively demanding exercises that target five cognitive skills: attention, coordination, memory, perception, and reasoning. Participants will also complete the general cognitive function assessment at the end of the intervention period, and the differences between the cognitive scores obtained before and after this period will be used as the main outcome measure. Additional analysis will be performed to better characterize the impact of the CCT by exploring the role of the age of the participants, their self-perceive health at baseline, the intensity of the training and the time from initial COVID-19 infection.
This before-and-after study aims to evaluate the usefulness and efficacy of a personalized computerized cognitive training (CCT) to improve cognitive function among people with post-acute sequelae of COVID-19 (PASC).
