Post-COVID neurocognitive effects

This dataset originates from a quantitative research project designed to investigate psychiatric, neuropsychological, and self-reported physical outcomes associated with COVID-19 infection in adults during the pandemic period. Data collection comprised two complementary procedures: an initial online survey administered via Google Forms, which gathered sociodemographic information, COVID-19–related variables, and psychiatric symptoms assessed through an adapted version of the Brief Symptom Inventory (BSI), allowing participants to retrospectively report symptoms before the pandemic and at the time of data collection; and a neuropsychological assessment conducted remotely through scheduled video calls, using standardized instruments to evaluate cognitive domains such as attention, processing speed, executive functions, and memory. The dataset is organized to support descriptive analyses, group comparisons, and regression-based approaches examining associations between COVID-19 exposure, psychiatric symptoms, cognitive performance, and individual characteristics such as age and educational level, and may be reused for secondary analyses, methodological replication, or comparative studies on post-COVID mental health and cognitive outcomes. Some of the information is in Portuguese in the dataset.
