Abstract
The COVID-19 pandemic took a toll on everyone's lives, and patients with rare diseases (RDs) had to pay an even higher price. In this systematic review, we explored the impact of the COVID-19 pandemic on individuals with RDs from a psychological perspective. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we retrieved articles from the Google Scholar, Scopus, and PubMed databases focusing on 'COVID-19,' 'psychology,' and 'rare diseases.' Seventeen primary articles were identified (mainly from continental Europe). The results revealed the psychological effects of the pandemic on rare disease patients, including increased anxiety, stress, and depressive moods. This review also highlighted the increased vulnerability and reduced quality of life of rare disease patients during the pandemic, as well as the importance of telecare and psychological support as critical interventions for improving their well-being. There is an urgent need for multidisciplinary research and stronger healthcare systems to meet the unique challenges of rare disease patients, who represent 3.5-5.9% of the global population.
