Myoclonic jerks occur in a number of different syndromes. There is many classifications of myoclonus. It is preferred the Fejerman classification, slightly modified that present the following five groups: 1. Myoclonus without encephalopathy and without epilepsy, which includes physiological myoclonus; 2. Encephalopathies with non epileptic myoclonus, which includes Kinsbourne syndrome and certain types of hyperekplexia which pose differential diagnosis problems with reflex myoclonic epilepsy; 3. Progressive encephalopathies with myoclonic seizures which includes typical and atypical progressive myoclonus epilepsies; 4. Epilepsies and epileptic encephalopathies with myoclonic seizures, which includes severe epilepsies which leads to mental retardation, as Otahara syndrome, West syndrome and Lennox-Gastaut syndrome, and other epilepsies which present sometimes myoclonic seizures, as Landau-Kleffner syndrome, 5. Comprises true myoclonic epilepsies, differentiating syndromes recognized as idiopathic, -benign myoclonic epilepsy of infancy, reflex form of benign myoclonic epilepsy in infancy, eyelid myoclonic with absences, perioral myoclonic with absences and juvenile myoclonic epilepsy-, cryptogenic-severe myoclonic epilepsy of infancy, myoclonic-astatic epilepsy and epilepsy with myoclonic absences-, and symptomatic as the generalized myoclonus in children with static encephalopathies. The epileptic syndromes of the last group are described. Despite this classification, apparently clear, there is still a great deal of confusion and in clinical practice, many cases are difficult to classify.

Opsoclonus myoclonus syndrome (OMS) is an inflammatory neurological disorder, which is characterized by chaotic uncontrolled movements of the eyes and involuntary jerk-like movements of the body. Different modalities of treatment have been described in medical literature to treat OMS. Immunomodulatory treatment with either steroids or intravenous immunoglobulin has been considered. Our case was a 14-year-old boy who presented with fever, mild confusion, without any seizures or focal deficits. On examination, he had opsoclonus in his eyes and had cortical myoclonus in his hands and body. On evaluation, he had low platelets, normal metabolic workup, normal brain imaging, and cerebrospinal fluid showed lymphocytic pleocytosis. He was managed conservatively and had spontaneous improvement in opsoclonus myoclonus by 5th day of his illness and complete recovery in 2 weeks. Although dengue is primarily considered hematotropic virus, it can involve nervous system as well and manifest with OMS.
