Abstract
Background: At the end of 2019, COVID-19 was first detected in Wuhan. In March 2020, COVID-19 became a pandemic globally. Saudi Arabia registered the first case of COVID-19 on March 2, 2020. This research aimed to identify the prevalence of different neurological manifestations of COVID-19 and to assess the relation of the severity, vaccination state, and continuity of symptoms to the occurrence of these symptoms. Methods: Cross-sectional retrospective study was done in Saudi Arabia. The study was conducted on previously diagnosed COVID-19 patients by random selection using a predesigned online questionnaire to collect data. Data was entered through Excel and analyzed through SPSS version 23. Results: The study showed that the most common neurological manifestations in COVID-19 patients are headache (75.8%), changes in sense of smell and taste (74.1%), muscle pain (66.2%), and mood disturbance (depression, anxiety) (49.7%). Whereas other neurological manifestations such as weakness of the limbs, loss of consciousness, seizure, confusion, and vision changes are significantly associated with older individuals, this may lead to increased mortality and morbidity in these patients. Conclusion: COVID-19 is associated with many neurological manifestations in the population of Saudi Arabia. The prevalence of neurological manifestations is similar to many previous studies, where acute neurological manifestations such as loss of consciousness and convulsions are seen more in older individuals which may lead to increased mortality and worse outcomes. Other self-limited symptoms such as headache and change in smell function i.e., anosmia or hyposmia were more pronounced in those <40 years. This mandates more attention to elderly patients with COVID-19, to early detect common neurological manifestations associated with it, and to apply preventive measures known to improve the outcome of these symptoms.
