Introduction: Recent research has observed the ability of coronavirus disease 2019 (COVID-19) to spread in the brain from the respiratory system. The associated neurological disorder includes encephalopathies, inflammatory syndromes, stroke, peripheral neuropathies, and various other central nervous system disorders. This study aims to highlight the long-term neurological sequelae in patients with COVID-19 disease.
Methods: This long-term study was carried out in the COVID-19 unit of a tertiary care hospital in Pakistan from July 2020 to July 2021. After obtaining informed consent, we enrolled 1000 patients who recovered from COVID-19 and were discharged. The participants were followed up after 30 and 90 days.
Results: At the time of enrollment, there were 602 (60.2%) males and 398 (39.8%) females. The most common neurological symptom on 30-day follow-up was headache (8.8%), followed by insomnia. The most common neurological symptom on day 90 follow-up was insomnia (5.07%), followed by an altered sense of smell (3.3%).
Conclusion: COVID-19 tends to produce a wide range of neurological symptoms, ranging from headache to anosmia to increased risk of stroke, that complicates clinical management. Potential neurologic effects and drug interactions have been reported secondary to the medications used to treat COVID-19. In light of the aforementioned facts, COVID-19 could potentially have a long-term effect on the brain. Therefore, it is important that the clinicians must be aware of the potential neurologic complications. Lastly, proper follow-up is recommended that would aid in timely recognition and management of the neurological disorder.
