The Frequency of Neurological Symptoms in COVID-19 Patients at a Tertiary Care Hospital in Pakistan.

Introduction Coronavirus disease 2019 (COVID-19) primarily affects the pulmonary system and presents itself as shortness of breath, fever, and cough. However, it may affect other systems as well, including the nervous system. This study aimed to determine the frequency of neurological symptoms in COVID-19 patients and its association with the severity of the disease. Methods This cross-sectional study was conducted at a public sector tertiary care teaching hospital in Karachi, Pakistan, from April to July 2020. All patients with positive polymerase chain reaction (PCR) tests were included, except those with pre-existing neurological and psychiatric conditions. Results The most common neurological symptom was dizziness (17.5%), followed by headache (15.7%). Three (2.6%) patients had a stroke. Nine (7.8%) participants had a taste impairment, and another nine (7.8%) had a smell impairment. There was no significant difference in the frequency of neurological symptoms when severe and non-severe disease was compared. Conclusion Neurological symptoms are frequent in COVID-19. Care should be taken to identify them early. COVID-19 should be suspected in patients presenting with neurological abnormalities and should be included in the differential diagnosis to prevent further virus transmission.
