1,545 Possible Causes for Lower and Upper Limbs Affected, Myoclonic Jerking, Spike-and-Slow-Wave or Polyspike-and-Slow-Wave Discharges

  • Myoclonic Jerking

    ., adj myoclon ic. A single myoclonic arm or leg jerk is normal when the person is falling asleep. Myoclonic jerks are severe with grand mal seizures.[medical-dictionary.thefreedictionary.com] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[epilepsydiagnosis.org] These involuntary jerks are a symptom and not a disease. Myoclonic jerks are usually caused by some type of central nervous system ( brain and spinal cord ) disturbance.[healthblurbs.com]

  • 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] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[epilepsydiagnosis.org] ., adj myoclon ic. A single myoclonic arm or leg jerk is normal when the person is falling asleep. Myoclonic jerks are severe with grand mal seizures.[medical-dictionary.thefreedictionary.com]

  • Epilepsy

    So the jerks were considered as cortical origin and generalized myoclonic seizure was confirmed.[ncbi.nlm.nih.gov] ) discharges or generalized spike wave and polyspike wave activity.[brain.oxfordjournals.org] People with JME can have absence seizures, myoclonic (muscle-jerking) seizures, and generalized tonic-clonic seizures.[everydayhealth.com]

  • Myoclonic-Astatic Epilepsy

    The involvement of these structures might predispose to the typical seizure semiology of myoclonic jerks observed in MAE.[ncbi.nlm.nih.gov] Myoclonic-atonic seizures with falls are the defining symptoms. • EEG shows frequent generalized discharges of spike/polyspike-slow wave at varying frequencies of 2.5 to 3[medlink.com] jerks, by using burst-locked EEG averaging where necessary.[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]

  • Early Infantile Epileptic Encephalopathy Type 6

    As the affected children grow up, they develop myoclonic jerking, and their seizures may become refractory to treatment. Synonym: severe myoclonic epilepsy of infancy[medical-dictionary.thefreedictionary.com] Four children had generalized spike and slow wave or polyspike and slow wave.[neurology.org] Generalized ictal myoclonic jerks: The generalized ictal myoclonic jerks are always preceded by clear-cut spike-wave discharges.[icnapedia.org]

  • 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] .  Inter-Ictal EEG  Initial -20% show normal BG with photoparoxysmal discharges of spikes/ polyspikes-slow waves.  Within 1 year, EEG - abnormal slow BG with frequent asymmetrical[slideshare.net] Early Myoclonic Encephalopathy starts in the first 10 days of an infant’s life with erratic small jerks (i.e. myoclonic seizures).[seizuresinfant.com]

    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] Interictal EEG may demonstrate the following characteristics: A slow background that can be constant or transient Awake – Diffuse slow spike wave Non-REM sleep – Discharges[emedicine.medscape.com] 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]
