978 Possible Causes for Jerking, Myoclonic

Did you mean: Jerking, myoclonus

  • Juvenile Myoclonic Epilepsy

    Juvenile myoclonic epilepsy affects an estimated 1 in 1,000 people worldwide. Approximately 5 percent of people with epilepsy have juvenile myoclonic epilepsy .[] We report on four patients with juvenile myoclonic epilepsy in whom the coexistence of praxis- and language-induced jerks was documented in video-polygraphic EEG recordings[] The characteristic signs of JME are brief episodes of involuntary muscle twitching.[]

  • Idiopathic Generalized Epilepsy

    Clinical aspects of juvenile myoclonic epilepsy.[] IGE manifestations include absence seizures, myoclonic jerks and generalized tonic clonic seizures.[] Children with this disorder often present with head drops and brief arm jerks.[]

  • Myoclonic Jerking

    This volume is the first comprehensive text and clinical reference on idiopathic myoclonic epilepsies of infancy, childhood, adolescence, and adulthood.[] A single myoclonic arm or leg jerk is normal when the person is falling asleep. Myoclonic jerks are severe with grand mal seizures.[] And this quick jerking can’t be controlled.[]

  • Myoclonic Seizures

    ) and myoclonic-astatic epilepsy (MAE).[] Abstract A 15-year-old girl with clinical and serologic evidence of active Epstein-Barr virus infection presented with a new onset of myoclonic jerks, confirmed on electroencephalogram[] It is defined as “spontaneous, regular or irregular, clonic muscle twitching of cerebral cortical origin, sometimes aggravated by action or sensory stimuli, confined to 1[]

  • Myoclonus-Dystonia Syndrome 11

    Definition A myoclonic dystonia. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures.[] Myoclonus dystonia, a genetic form of dystonia, is characterized by rapid jerking movements alone or in combination with the sustained muscular contractions and postures of[] Individuals with myoclonic dystonia exhibit symptoms of dystonia plus very prominent myoclonic movements.[]

  • Subacute Sclerosing Panencephalitis

    Clinical onset typically manifests with progressive intellectual deterioration, behavioral changes, and myoclonic jerks.[] A physical examination may reveal: Damage to the optic nerve, which is responsible for sight Damage to the retina, the part of the eye that receives light Muscle twitching[] Clinical presentations are variable including behavioral-cognitive change, myoclonic seizure, visual problem, spasticity or abnormal movement.[]

  • Myoclonic-Astatic Epilepsy

    RESULTS: LGS: neurophysiologic analysis indicated that jerks and the accompanying premyoclonic spikes showed latency differences between sides (mean /- SD, 18 /- 5 ms for[] ) and myoclonic-astatic epilepsy (MAE).[] The involvement of these structures might predispose to the typical seizure semiology of myoclonic jerks observed in MAE.[]

  • Atonic Seizures

    BACKGROUND: Epilepsy with myoclonic-atonic seizures, also known as myoclonic-astatic epilepsy or Doose syndrome, has been recently linked to variants in the SLC6A1 gene.[] Ethosuximide (absences) and clonazepam (myoclonic jerks) may be useful.[] Diagnosis of EMAS was performed according to the following criteria: (1) onset of myoclonic, myoclonic-atonic, or atonic seizures at between 7 months and 6 years of age; ([]

  • Myoclonic Epilepsy of Infancy

    Abstract Severe myoclonic epilepsy of infancy (SMEI) is a newly recognized epileptic syndrome.[] We report a group of five children with excessive myoclonic jerks, only during sleep, and abnormal EEG during the events.[] A 14-year-old boy had a history of repeated episodes of myoclonic jerks of the shoulders and upper limbs in infancy (age 5 months).[]

  • Epilepsia Partialis Continua

    Abstract We used electroencephalographic (EEG) dipole analysis to investigate the generators of spikes with and without myoclonic jerks in a 12-year-old patient with epilepsia[] EEG revealed both correlation and absence of correlation between spikes or sharp waves and myoclonic jerks.[] Myoclonic jerks progressed to epilepsia partialis continua within 5 days of admission to the hospital.[]
