Objective: Hypokinetic movement disorder and parkinsonian picture has been well described in literature following covid-19 but hyperkinetic MDS are very in global literatures. To investigate the epidemiology,clinical picture,the diagnostic and therapeutic challenges in patients hyperkinetic MDS in this context and to know the time schedule of the onset of the MDS with exploring the possible pathogenesis Background: Infections are up to 20% of movement disorders.The most frequent agents are beta-hemolytic streptococcus,and flavivirus causing Japanese encephalitisThe role of the viral stimulation of microglial activation in neuroinflammation has regained attention in the context of covid19 Methods: Patients of MDS attended the clinic from 31st march 2020 to March 2022,with recent onset of hyperkinetic movements were screened. Subjects had medical history either prior to the study or medical history reviewed by physicians suggestive of covid.PCR +VE or Presence of covid antibody in blood or csf in patients with recent onset hyperkinetic MDS within 6-12 weeks of onset of symptoms except.Ventilatory cases Other markers were used to rule out other viral infections causing MDS.MRI brain and EEG as a routine in all Immune markers in very selected cases in suspected immuomediated MDSThe attempted treatment were symptomatic and immunotherapy Results: In last 2 years 50 cases of new onset Hyperkinetic MDS are recorded, out of which only 9 cases were directly or indirectly linked to Covid,Nystagmus, orofacial dyskinesia and segmental or generalized myoclonus and ataxic gait associated delirium,tremors and ocular movement disorders along with epileptic seizures are also seen.Positive EEG findings are in the form of diffused bihemispheric slowing or periodic complexes with polyspikes at irregular interval and delta brush in few cases .MRI findings varied between non-specific changes to bitemporoparietal hyperintensities in flair and T2 both cortical and subcortical or bilateral basal ganglia. Treatment response in all the cases are statisfactory Conclusion(s): observational study revealed MDS in covid do happen Myoclonus is the most Frequent movement disorder associated with COVID-19 followed by dystonia and tremors .pathophysiology included neuro inflammation, autoimmune mechanisms and small vessels thrombosis hence not be co-incidental , response to steroid also s/o immune mediated.
