Background: COVID‐19 neurological manifestations were demonstrated during the pandemic, including cognitive impairment. Objectives: To determine the prevalence of cognitive and behavioral complaints (such as dementia, MCI or SCD) in a outpatient sample with recent SARS‐COV2 infection. Specific: Evaluate the association of cognitive impairment with the presence of the polymorphism found in the APOE gene and with respiratory disease Method: Observational, longitudinal, prospective clinical study. Inclusion criteria: patients with confirmed Covid‐19. Patients are evaluated in an outpatient clinic. They are evaluated through a standardized attendance record, with somatic and cognitive neurological assessment. Cognitive assessment involves the application of cognitive (ACER, MMSE and CDR), functional (Pfeffer) and psychiatric (GDS or Beck) screening instruments, in addition to subsequent extensive neuropsychological assessment. In addition, APOE polymorphism is analysed. Results: To date, 200 patients were evaluated. The average age is 46.5 years, with 65.4% female, 79.16% with 8 or more years of schooling, in addition to 57.5% of the sample with cognitive complaints. Conclusions: The results so far in our study demonstrate that cognitive complaints are frequent in patients even in the chronic phase of the disease. [ABSTRACT FROM AUTHOR]

This report describes a rare case of acquired Ondine's curse. The patient developed central sleep apnea syndrome named Ondine's curse after a brainstem infarction. Lesions involving the descending medullocervical pathways that subserve automatic breathing can result in this syndrome. [ABSTRACT FROM AUTHOR]
