Objective To summarize the diagnosis and treatment experience of patients with Guillain-Barré syndrome(GBS)with positive anti sulfatide antibody in CSF.Methods The clinical data of a case of patient with GBS with positive anti sulfatide antibody in CSF in Department of Neurology,The Affiliated Brain Hospital of Nanjing Medical University in January,2023 were retrospectively analyzed,and the relevant literatures were reviewed.Results Two cases with GBS with positive anti sulfatide antibody in CSF from 2 literatures were retrieved,a total of 3 cases were retrieved.All cases were males.The onset duration was 4-6 d.Two patients with GBS with positive anti-sufatide antibody in CSF developed limb weakness,severe back and limb pain.Albuminocytologic dissociation in CSF and inefficacy of immunoglobin were found in the two cases.Severe hyponatremia secondary to intravenous immunoglobin was observed in our case.One patient presented with cranial nerve damage with mild elevation of CSF protein and improvement after immunoglobulin.Conclusion The plasmapheresis was recommended for the patients presenting with limb weakness with positive anti-sulfatide antibody in CSF in order to prevent inefficacy and severe hyponatremia secondary to intravenous immunoglobin.

Epilepsy is often comorbid with other neuropsychiatric conditions,which are known as epilepsy comor-bidities.Among these conditions,the comorbidity of epilepsy and migraine is very common.Although they are two differ-ent diseases,they overlap in terms of pathophysiological features and clinical symptoms,and several anti-seizure medica-tions(ASMs)have been proved to be effective in migraine.However,there are still controversies over the concept of epi-lepsy comorbid with migraine,and there is often a lack of effective treatment for migraine due to missed diagnosis or misdi-agnosis.In order to improve the ability for identification and precise treatment of epilepsy comorbid with migraine among clinicians,this article elaborates on the possible mechanism of epilepsy comorbid with migraine and discusses the con-cept,identification,and diagnosis and treatment regimens for epilepsy comorbid with migraine by considering the tempo-ral association between headache symptoms and epileptic seizures,with reference to the classification of epilepsy comorbid with migraine and related diagnostic criteria in Chinese expert consensus(2019)and the ICHD-3-2018 guidelines issued by the International Headache Society.
