The Impact of the COVID-19 Pandemic on the Health of People with Mental Disorders

Abstract

The aim of the review was to analyze published studies on the impact of the COVID-19 pandemic on the health status (mental and physical) of people with mental disorders. Materials and methods: by keywords “COVID-19”, “depressive disorders”, “affective disorders”, “schizophrenia”, “anxiety disorders” search for papers in English and Russian in the databases MEDLINE/ PubMed, Scopus, Web of Science, eLibrary for the period from 2017 to 2022 was carried out. Conclusion : the analysis of published works has demonstrated that factors such as social distancing, isolation, or changing the availability of medical services can have a significant influence on the health of people with mental disorders. It has been established that people suffering from mental illness are at a higher risk of contracting COVID-19, they have less effective post-vaccination immunity and have a more severe course of the disease. The past coronavirus infection can lead to both an increase in pre-existing symptoms of a mental disorder, and the emergence of new ones. Possible physiological mechanisms of mental disorders after past COVID-19 include a wide range of pathogenetic processes: from prolonged systemic inflammation of varying intensity to vascular microthrombosis and neurodegenerative changes. Cognitive impairment during COVID-19, associated with damage to brain structures by the virus, may exacerbate existing psychopathological symptoms. The special features of psychopathological symptoms that develop in response to a pandemic situation are closely related to the structure of the previous mental status of patients, and therefore the types of psychosocial assistance needed is different for people with various mental disorders.
