Clinical Manifestations

Post-COVID19 syndrome is characterized by signs and symptoms that occur within 3 months of the onset of COVID19 acute phase and last at least 2 months. In the past 3 years, cognitive impairment has frequently been associated with COVID19 with descriptions of attentional, executive, memory, and language disorders. Many studies have assessed these cognitive disturbances using online and telephone tests, often in isolated interviews on a cross-sectional design in high-income countries. Few studies evaluated the role of cognitive rehabilitation in this situation. Objective: To characterize the cognitive profile and psychological batteries of this population pre-and post-cognitive rehabilitation after 6 months. We selected patients younger than 65 years of age with COVID19 and cognitive symptoms for more than 3 and less than 6 months and no records of previous neurodegenerative or severe psychiatric diseases. They were evaluated 3 times (0, 3, and 6 months) with cognitive battery tests and questionnaires and later by a neuropsychologist for evaluation and cognitive training. 46 patients were recruited; 41 matched the inclusion criteria and were referred to cognitive rehabilitation. 33 finished the third medical assessment. General and demographic data are shown in Table 1. Cognitive assessment in the first evaluation is demonstrated in Table 2. Only 32% of the sample had an unremarkable evaluation, and 68% were classified as having Cognitive impairment no dementia (CIND). Table 3 demonstrates patients that completed the follow-up and the changes in cognitive tests at 6 months after rehabilitation, showing a statistically significant (p
