1,557 Possible Causes for Frontal Focal Spikes, Lower and Upper Limbs Affected, Myoclonic Jerking

  • Benign Adult Familial Myoclonic Epilepsy

    By the jerk-locked averaging method, a positive spike time-locked to the myoclonic jerk was demonstrated in four patients before 15-20 msec of myoclonic jerk.[ci.nii.ac.jp] […] childhood epilepsy with centrotemporal spike -childhood epilepsy with occipital paroxysms Generalized epilepsies & synd.[enotes.tripod.com] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[epilepsydiagnosis.org]

  • Epilepsy

    The diagnosis of frontal lobe epilepsy (generalized tonic-clonic seizures secondary to focal impaired awareness seizures and myoclonus) was made.[ncbi.nlm.nih.gov] So the jerks were considered as cortical origin and generalized myoclonic seizure was confirmed.[ncbi.nlm.nih.gov] Neuroimaging studies were unremarkable and electroencephalograms showed high voltage 200-400uV, 2-2.5 Hz generalized spike-and-waves and polyspikes with alternating frontal[ncbi.nlm.nih.gov]

  • Juvenile Myoclonic Epilepsy

    The myoclonic jerks occur rarely in EMA. They are usually mild and are freqently restricted to the upper extremities.[ncbi.nlm.nih.gov] All of these patients were contacted and asked specifically about myoclonic jerks.[ncbi.nlm.nih.gov] Myoclonic jerks or seizures Myoclonic jerks or seizures without impairment of consciousness are the cardinal symptoms of JME.[emedicine.medscape.com]

  • Idiopathic Generalized Epilepsy

    Myoclonic-astatic seizures consist of symmetric myoclonic jerks followed by periods of absent muscle tone that can result in falls.[symptoma.com] This epilepsy is characterized by absence seizures concurrent with myoclonic jerks, typically occurring several times daily.[en.wikipedia.org] […] six cases (18%) with myoclonic jerks and tonic–clonic seizures.[jnnp.bmj.com]

    Both patients had early infantile seizures characterized by fragmentary myoclonic jerks associated with burst-suppression pattern on electroencephalography.[ncbi.nlm.nih.gov] Interictal EEGs of the patients with ZS showed infrequent bilateral multifocal spikes, predominantly in the frontal and pre-frontal motor cortex Patients with NALD had tonic[graphyonline.com] Early Myoclonic Encephalopathy starts in the first 10 days of an infant’s life with erratic small jerks (i.e. myoclonic seizures).[seizuresinfant.com]

  • Lennox-Gastaut Syndrome

    In such cases, massive myoclonic jerks, myoclonic-atonic attacks, as well as atonic seizures may occur, though much less frequent and severe than the other manifestations.[epilepsyontario.org] We did not include patients with interictal electrographic activity characterized by multifocal spikes, focal delta activity different to delta with maximum in the frontal[omicsonline.org] Lennox and Davis first correlated the slow spike-and-wave EEG pattern with a distinctive group of clinical manifestations including specific seizure types (myoclonic jerks[medlink.com]

  • Juvenile Absence Epilepsy

    Interictal and ictal EEG is characterized by focal generalized spike-wave discharge occasionally prominent in the frontal region.[1pdf.net] A total of 33 patients (47%) also had myoclonic jerks with a mean age at onset of 16 years.[medlink.com] Focal discharges were more frequent in the frontal regions 19,25. They may be isolated spikes, sharp waves, slow waves, or spike-and-wave complexes 7,16,21.[scielo.br]

  • West Syndrome

    The patient presented with segmental myoclonic jerks at the age of 6 weeks, and infantile spasms at the age of 3.5 months. Her seizures were resistant to treatment.[ncbi.nlm.nih.gov] jerks of the upper limbs, mainly on awakening, synchronous with the generalized discharges of 4 Hz spike-wave occurring at 12 years of age and by co-occurrence of a later[ncbi.nlm.nih.gov] Initially, he had refractory convulsions of focal, generalised, and myoclonic jerks, not responding to multiple anticonvulsants. He also had choreoathetoid movements.[ncbi.nlm.nih.gov]

    Benign neonatal sleep myoclonus, an entity characterized by (1) neonatal onset, (2) myoclonic jerks only during sleep, (3) abrupt and consistent cessation with arousal, (4[ncbi.nlm.nih.gov] jerks during non REM sleep disappear when baby is awake, EEG is normal and spontaneously resolve by 2 months of age. 23.[slideshare.net] Now, you might be confused as to the difference between a clonic and and myoclonic seizure. Both of them involve jerk or shock-like movements.[study.com]
