Additionally, the disease is associated with the long COVID syndrome, in which there is persistence of the effects and symptoms of the acute phase. In recent years the literature has shown relevant data on long COVID, but there is still a need to deepen the knowledge about these long term manifestations. Thus, the present study aimed to describe the main neurological sequelae resulting from SARS-CoV-2 infection in non-hospitalized population during the long phase of the disease, gathering scientific evidence through an integrative review of the prevalence of symptoms, patient profile, duration and severity of sequelae, risk factors, comorbidities, and possible nervous system structural damage. The PubMed/Medline database was used with descriptors and, at the end of the screening process with predefined inclusion and exclusion criteria, 22 studies were included. A group of neurological symptoms associated with long COVID was identified: myalgia, dysgeusia, memory alterations, olfactory dysfunction, dizziness, and pain. Most patients presented multiple symptoms that lasted for more than one year with a significant impact on quality of life. The main risk factors were dyslipidemia, age, ethnicity, muscle/ joint pain, and sex.

GR explained 41.33% of the variation in HAT CRH of the gene, and age plus race explained an additional 3.56% of the variation in HAT CRH of the gene. The findings of this study suggest that perceived stress and GR among young Black women were associated with higher levels of HAT of the CRH gene, which may contribute to adverse pregnancy outcomes such as preeclampsia and preterm birth.
