Neurological Consequences of Covid-19 - Web app design for behavioral and electrophysiological tests

Covid-19 infection can cause persistent symptoms, including fatigue, disorientation, concentration difficulties and memory problems, long after recovery. In the proposed project, an application was developed to obtain information about key behavioural markers indicative of neuronal integrity (sensory integration) and cognitive functioning (attention and memory) as biomarkers of Covid-19 neurological damage. This is done with an online study, in order to be able to relate the effects and severity in terms of persistent symptoms in patients who have already been infected. The application allows participants to perform a battery of tests, consisting of a series of cognitive tasks with visual and auditory stimuli. From the answers given by users, behavioural markers will be obtained, which will be recorded in the application. The purpose of this is to centralise and streamline the process of obtaining information through the use of technology. The behavioural markers to be assessed are: 1. Speed and accuracy of response to visual and auditory stimuli, 2. The ”temporal binding window” of sensory integration, 3. This paper describes the project, the methodology employed and provides details on the design. In addition, the architecture of the system and its individual parts are presented.
