Evaluation of Neuropsychiatric Complications in Hospitalized COVID-19 Patients

Previous research has shown that COVID-19 patients are at risk of developing mental disorders. Limited number of studies about psychiatric and neuropsychiatric presentations in hospitalized COVID-19 patients is currently available.

Subjects were 172 patients diagnosed with COVID-19 and requiring inpatient care, hospitalized at reprofiled clinics of the university hospital. The study aimed to quantify psychiatric symptoms, and determine correlations with agitation, BMI, mortality, and other variables (age, sex, oxygen therapy, intubation, etc.).

Mental disorders due to known physiological conditions were of highest prevalence (n=105, 62.9%), followed by anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders (n=34, 20.4%), and dementia (n=21, 12.6%) in COVID-19 patients. Depressive disorders (n=13, 7.9%), alcohol related disorders associated with withdrawal symptoms (n=10, 6%), and schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders (n=4, 2.4%) were less common. Patients diagnosed with mental disorders due to known physiological conditions were significantly older compared to patients with other diagnoses. The depression was observed more commonly in patients treated with high-flow nasal oxygen (HFNO), and patients disconnected from invasive mechanical ventilation (IMV). Mixed anxiety-depressive symptoms were observed in 23.8% of the patients (n=41), and they were more prevalent in younger patients compared to patients without anxiety-depressive symptoms. Agitated patients were significantly older than non-agitated patients. No connection was observed between the occurrence of agitation and treatment with HFNO, nor in case of patients disconnected from IMV; however, the relationship between agitation and death proved to be statistically significant (OR = 5.9, 95% CI 2.33-15.29).

Analysis of psychiatric and neuropsychiatric presentations in COVID-19 patients and their correlation with multiple variables provides a better understanding of the effect of infection on mental health, and brings forth a necessity of transdisciplinary approach in handling COVID-19 patients.
