Non-epileptic myoclonus and mitochondrial encephalomyopathy.
Two brothers presented to us with a progressive myoclonic syndrome with slight cerebellar symptoms. Neurological examination disclosed moderate cerebellar signs and pale optic discs; asymmetric, asynchronous and arrhythmic myoclonus, an arrthesthesic deficit and no muscular weakness. EEG background activity was moderately slow with no irritative discharges. CT was normal in both cases. Intermit...
متن کاملNegative myoclonus induced by cortical electrical stimulation in epileptic patients.
Negative myoclonus (NM) is a motor disorder characterized by a sudden and abrupt interruption of muscular activity. The EMG correlate of NM is a brief (<500 ms) silent period (SP) not preceded by any enhancement of EMG activity (i.e. myoclonus). This study investigated the role of premotor cortex (PMC), primary motor cortex (MI), primary somatosensory area (SI) and supplementary motor area (SMA...
متن کاملInduction of epileptic negative myoclonus by oxcarbazepine in symptomatic epilepsy.
Provocation of various seizure types including epileptic negative myoclonus and generalised atonic seizures is rarely observed in children treated with carbamazepine (CBZ). Provocation of the latter seizure types by oxcarbazepine (OXC) is not described in the literature. We report a four year-old boy with symptomatic epilepsy caused by left-sided cerebral atrophy of unknown origin who developed...
متن کاملEpileptic negative myoclonus as the presenting seizure type in rolandic epilepsy.
Epileptic negative myoclonus is an uncommon seizure type characterized by a sudden, brief loss of muscle tone that may lead to falling. It has been associated largely with benign childhood epilepsy with centrotemporal spikes (rolandic epilepsy), although it may also be a feature of other epileptic syndromes. In patients with rolandic epilepsy, epileptic negative myoclonus usually appears during...
متن کاملPrimary generalised epileptic myoclonus: a frequent manifestation of minipolymyoclonus of central origin.
A group of patients with myoclonus is described whose jerks are preceded by a bilaterally synchronous, frontocentrally predominant, negative cerebral potential in the EEG. This potential may be a slow wave with variable timing in relation to EMG bursts, and in this circumstance the muscle jerks are usually small amplitude and multifocal ("minipolymyoclonus"). The cerebral negativity can also be...
