Obsessive-Compulsive Disorder During the COVID-19 Pandemic Process: A Narrative Review

This study aimed to review all empirical contributions published between March 2020 and June 2022, addressing the impact of the COVID-19 pandemic on obsessive-compulsive disorder in adults. We searched the literature in PubMed, Google Scholar, and Web of Science. A total of 543 articles were scanned and 73 full-text articles were identified. Reviews, comments, letters to the editor, and case reports (except case series) were excluded. It was determined that 42 articles met the inclusion criteria, 6 studies involving only children and adolescents were excluded, and 36 were decided on their suitability for our study. The analysis determined that COVID-19 had an impact on obsessive-compulsive disorder. Characteristics such as liability for harm and unacceptable thoughts influenced the symptoms as well as contamination and washing. Some studies showed an increase in the severity of obsessive-compulsive symptoms, while some reported no worsening but improvement with treatment and follow-up. While some reported variations in outcomes related to sociodemographic characteristics and subtypes, some focused on the risk of suicide. There were also studies conducted on special groups such as pregnant women or healthcare workers. The results were controversial. While available data contain more information on worsening obsessive-compulsive disorder symptoms, data on the status of patients under treatment were scarce. There were not enough studies evaluating follow-up results. Influencing factors such as sociodemographic characteristics, subtypes, comorbid conditions, treatment, and support did not seem to have been adequately addressed.
