In addition, MRI scans showed no signs of cytotoxic lesions of the corpus callosum (CLOCC), which have been described recently in a fraction of patients with COVID-19-related encephalopathy [25, 26, 31]. 2020;7(11):2221–30.

Acute cerebellar Ataxia in COVID-19 infection: a case report. BMC Infect Dis 21, 298 (2021). 2020;7(8):974–6. Part of Sometimes cerebellar ataxia can result from infection, which causes inflammation in the cerebellum, impairing its ability to function normally. J Nucl Med. In terms of infection, treating the infection should lead to recovery from ataxia. Trendelenberg's gait. Eur J Neurol. A case with cerebellitis associated with acute SARS-CoV-2-induced pneumonia has been described recently [7]. FDG-PET was performed 13 days after onset of cerebellar symptoms and showed normal cerebellar and cerebral metabolism (Fig. T-cell immunodeficiency diseases include severe combined immunodeficiencies (SCIDs), Wiskott-Aldrich syndrome, ataxia telangiectasia, DiGeorge syndrome (22q11.2 deletion syndrome), immuno-osseous dysplasias, dyskeratosis congenita, and chronic … 2020;7(8):977–9. An in vitro study showed extensive accumulation of anti-Jo antibodies in Purkinje cells after internalization leading to cell death and cerebellar degeneration [34]. This research was partly funded by the Clinical Research Priority Program “Comprehensive Genomic Pathogen Detection” of the University of Zurich. If the injury damages the cerebellum, cerebral ataxia can occur. Google ScholarÂ. IR had a major role in the acquisition, analysis and interpretation of the clinical and CSF data and revised the manuscript. Liotta EM, Batra A, Clark JR, Shlobin NA, Hoffman SC, Orban ZS, Koralnik IJ. Likewise, if hypothyroidism is causing ataxia, then treatment of this condition with hormone therapy should remove the ataxia symptoms. 2020. https://doi.org/10.1097/WNO.0000000000001129. Regarding the mild cerebellar atrophy detected in the MRI, the patient did not have any history of alcohol abuse, gluten hypersensitivity or other pre-existing cerebellar disease.

Notably, SARS-CoV-2 RT-PCR [27] from CSF was negative. Symptoms include fever, irritability that gets worse over time, difficulty walking, and speech impairment that can persist for days or even weeks. The datasets used and/or analysed during the current study are available from the corresponding author on reasonable request. Other causes of ataxia such as other viral infections, other autoimmune and/or paraneoplastic diseases or intoxication were ruled out.

Purkinje cell death after uptake of anti-Yo antibodies in cerebellar slice cultures. Such a mechanism has not been described in SARS-CoV-2 infection yet, and in our case we believe a direct SARS-CoV-2 infection of the cerebellum is highly unlikely because of normal CSF cell counts, the negative SARS-CoV-2 PCR test of the nasopharyngeal swab on day 6 of hospital admission despite persistent cerebellar symptoms, and, most importantly, because of absence of SARS-CoV-2 RNA in the CSF and intrathecal SARS-CoV-2-specific antibody production.

No pathological nystagmus was observed. 2020;4(3):352–4. Introduction to the musculoskeletal system, Nerves, vessels and lymphatics of the abdomen. Rachel Baxter BSc, MSc Cerebellar ataxia is a form of ataxia that originates from abnormalities such as inflammation in the occipital and temporal lobes of the cerebellum. 2019;10(9). Laboratory results showed no increase in inflammatory markers in peripheral blood, in particular CRP and white blood cell count were normal. Classical examples of autoimmune cerebellar ataxia are GAD antibody-associated and paraneoplastic Jo antibody-associated cerebellar ataxia. Good Clinical Practice (GCP) is an international ethical and scientific quality standard for designing, conducting, recording and reporting trials that involve the participation of human subjects.

Nonparaneoplastic autoimmune cerebellar ataxias. Sanguinetti S, Ramdhani RA. The changes in metabolism caused by hypothyroidism lead to cerebellar dysfunction and degeneration. Article  CAS  Some exhibit cerebellar cortical atrophy, which involves degeneration of Purkinje cells in the cerebellar cortex and loss of facultative retrograde cells in the inferior olive (or inferior olivary nucleus). Further research defining epidemiological, clinical, laboratory and therapy response characteristics is needed to prove association or causality regarding neurological dysfunctions. 2019;32(3):484–92. We strongly assume a subacute post-infectious cerebellar ataxia with near-complete remission to be the cause of the neurological deficits which occurred after resolution of SARS-CoV-2-induced respiratory illness . SARS-CoV-2-specific antibodies were positive in serum, but there was no intrathecal SARS-CoV-2-specific antibody production. His vital signs on admission were normal. GAD-specific cytotoxic T cell infiltrates associated with neuronal damage and microglial activation were found in post-mortem histopathological studies of patients with GAD antibody-associated encephalitis [35]. CSF testing including cell count, protein, CSF/serum albumin ratio and Reibergram was normal. 2020;77(6):683–90. 2021 MW revised the manuscript for intellectual content. The mechanisms, by which SARS-CoV-2 may cause central nervous system (CNS) dysfunction, remain unclear until now, but several hypothecical explanations are currently under discussion. c and d: Sagittal T2–fluid attenuated inversion recovery magnetic resonance imaging sequences 5 days after onset of ataxia, i.e. Article  Eur J Neurol. In patients with idiopathic, genetic, or cerebral palsy-caused cerebellar ataxia, there is no obvious cure. SARS-CoV-2 infection of the cerebellum was excluded by normal cerebrospinal fluid cell counts and, most importantly, absence of SARS-CoV-2 RNA or intrathecal SARS-CoV-2-specific antibody production. 2021;60(1):73–6.
