Aim: To assess the effect of social isolation due to the coronavirus disease 2019 (COVID-19) pandemic on physical and mental health of Parkinson's disease patients treated at the University Hospital Center Rijeka.
Methods: This cross-sectional telephone study involved Parkinson's disease patients who had at least one control examination at University Hospital Center Rijeka in 2020 and were Croatian citizens. A questionnaire was used to obtain data on the socio-demographic characteristics and the severity of motor, anxiety, depression, and non-motor symptoms.
Results: The final sample included 87 patients. Most patients reported subjective worsening of motor symptoms. Patients who lived alone had worse motor scores than those not living alone. The majority of patients reported worsening of anxiety symptoms. Significant worsening of anxiety symptoms was found in patients who lived alone, had a longer disease duration, and had avoided check-ups. Fewer patients had depression symptoms than motor and anxiety symptoms. Significantly higher Hamilton Depression Rating Scale scores were observed in patients with a longer disease duration. Significant worsening of non-motor symptoms was identified in patients who lived alone, were less educated, had a longer disease duration, and had a higher Charlson comorbidity index.
Conclusion: Patients who live alone, have longer disease duration, are less educated, avoid check-ups, and have more comorbidities are more vulnerable to the negative effects of social isolation.
