Introduction: There are certain post-coronavirus disease (COVID) neurological syndromes which have been reported such as cerebrovascular diseases, cerebral venous thrombosis, peripheral neuropathy, encephalitis, encephalopathy, cerebellar ataxia, facial palsy, and myositis. However, most of these are isolated case reports. In this case series, we discuss the post-COVID neurological complications such as facial palsy, lateral rectus palsy, cerebellar ataxia, peripheral neuropathy, and stroke which occurred within 2 weeks after complete recovery from COVID. Methods: This multicentric case series is from three large tertiary care hospitals in northern and central India. We have reviewed seven patients with recent-onset neurological symptoms who had recovered from COVID infection within 2 weeks. We have retrospectively studied the clinical profile and radiological imaging during COVID infection. Results: Three out of these seven patients had received steroids during COVID treatment. None of our cases had any neurological manifestations during their COVID infection. The likelihood of neurotransmission through the cribriform plate via the olfactory bulb was low, as none of our patients had anosmia. None of the patients in the case series showed features of systemic hyperinflammatory syndrome, making the possibility of macrophage activation syndrome less likely. Conclusion: We hypothesize that antibodies against the coronavirus post recovery from COVID are responsible for these post-COVID neurological complications. Higher likelihood of these complications after rapid tapering off steroids may further corroborate this mechanism, as the antibody levels rise after steroid withdrawal. Titers of antibodies to SARS COV-2 virus in the postinfection period in these cases may have further helped prove our hypotheses which can be considered in future studies on the subject.
