Post-COVID-19 syndrome and related dysautonomia reduce quality of life, and increase anxiety and depressive symptoms: evidence from Greece

BackgroundPost-COVID-19 syndrome affects a significant number of SARS-CoV-2 infected individuals even asymptomatic cases causing several neurological and neuropsychiatric symptoms and signs. Materials and MethodsAn online cross-sectional study with a convenience sample was conducted in Greece from November 2022 to January 2023. We measured demographic and clinical characteristics of patients, post-COVID-19 dysautonomia, quality of life with the EQ-5D-3L, and anxiety and depressive symptoms with the Patient Health Questionnaire-4. ResultsStudy population included 122 patients with post-COVID-19 syndrome. One out of four patients (27.8%) manifested post-COVID-19 dysautonomia, while mean duration of COVID-19 symptoms was 11.6 months. Anxiety and depressive symptoms were worse after the post-COVID-19 syndrome (p<0.001 in both cases). A statistically significant reduction in quality of life was observed among patients after the post-COVID-19 syndrome (p<0.001 for both EQ-5D-3L index value and EQ-5D-3L VAS). Post-COVID-19 dysautonomia increased depression symptoms after the post-COVID-19 syndrome (p=0.02). We found a negative relationship between duration of COVID-19 symptoms and quality of life (p<0.001). Moreover, our results showed that depressive symptoms were more often among females after the post-COVID-19 syndrome (p=0.01). Also, quality of life was lower among females than males (p=0.004 for EQ-5D-3L index value, and p=0.007 for EQ-5D-3L VAS). ConclusionsOur results suggest that post-COVID-19 syndrome causes a tremendous impact on patients quality of life and mental health. In addition, we found that the groups most psychologically affected were patients with post-COVID-19 dysautonomia, females, and patients with longer duration of symptoms. Policy makers should attach priority to vulnerable groups in future psychiatric planning. Policy measures should focus on mental health of post-COVID-19 patients who seem to be particularly vulnerable.
