randomised clinical trial to evaluate the efficacy of an online cognitive rehabilitation programme (coperia-cog) for patients with persistent covid-19

Conditions: COVID-19; Neuro-Degenerative Disease; Psychological; SARS CoV 2 Infection

Summary: the pandemic caused by sars-cov-2 infection has led to the emergence of diffuse and heterogeneous persistent symptoms in addition to the well-known acute symptoms, which have come to be referred to as persistent covid. in particular, one of the frequent complaints of patients with a previous diagnosis of covid is impaired cognitive ability. various cognitive rehabilitation programmes have benefited from incorporating the methodology of so-called "serious games" are designed to train or change behaviour while entertaining players. the design of the online rehabilitation programme (coperia-cog) took into account the principles of neuropsychological rehabilitation (neuropsychological pre-assessment, operational goal setting, task prioritisation and continuous feedback system) and combined different individual techniques, such as restitution and compensation. patients treated with coperia-cog will show neuropsychological improvements in verbal memory compared to the waiting list group. the main objective is to identify differences in long-term memory in patients treated with coperia-cog vs. patients on the waiting list. for this purpose, both groups will be evaluated through ravlt, taking the long-term memory subtest as a reference, comparing the results before and after the active group performs the online training with coperia-cog. the coperia platform is a cloud platform that provides a range of ict tools for monitoring and aiding the recovery of patients with persistent covid. to achieve this goal, the platform will store patient data to which artificial intelligence techniques will be applied to perform an assessment of the affected person.
