1,546 Possible Causes for Active Generalized Spikes and Polyspikes, 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] The EEG shows generalized polyspike and spike-and-wave discharges, frequently precipitated by photic stimulation.[clinicalgate.com] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[epilepsydiagnosis.org]

  • 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]

  • 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] spike-polyspike and waves.[ncbi.nlm.nih.gov] All of these patients were contacted and asked specifically about myoclonic jerks.[ncbi.nlm.nih.gov]

  • Epilepsy

    So the jerks were considered as cortical origin and generalized myoclonic seizure was confirmed.[ncbi.nlm.nih.gov] 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] […] tonic-clonic seizures and nonconvulsive status epilepticus. 1 , 2 The electroencephalogram (EEG) shows generalized spike- or polyspike-wave activity at more than 2.5 Hz without[jamanetwork.com] jerks, by using burst-locked EEG averaging where necessary.[ncbi.nlm.nih.gov]

  • 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] Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[ncbi.nlm.nih.gov] The abnormalities included generalized spike-wave and/or spike-polyspike morphology in majority.[annalsofian.org]

  • Familial Infantile Myoclonic Epilepsy

    One fifth of patients have photosensitivity, with myoclonic jerks precipitated by photic stimulation.[medlink.com] The EEG shows a normal background with 3.5–4-Hz generalized spike–wave discharge, at times polyspike and wave.[neupsykey.com] Sometimes, similar myoclonic jerks can occur also after an infectious event, and for these cases the more appropriate term of “parainfectious myoclonic jerks” has been introduced[movementdisorders.org]

  • 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] Interictal EEG showed findings characteristic of LGS: generalized slow spike-wave complexes, multifocal sharp waves, generalized polyspikes and paroxysmal fast activity during[ncbi.nlm.nih.gov] […] and more frequent, consisting of polyspikes and slow waves REM sleep – Decreased spike waves Ictal EEG may demonstrate the following characteristics: Tonic seizure – Diffuse[emedicine.medscape.com]

  • Early Infantile Epileptic Encephalopathy Type 3

    Both patients had early infantile seizures characterized by fragmentary myoclonic jerks associated with burst-suppression pattern on electroencephalography.[ncbi.nlm.nih.gov] Early Myoclonic Encephalopathy starts in the first 10 days of an infant’s life with erratic small jerks (i.e. myoclonic seizures).[seizuresinfant.com] […] epileptic encephalopathy which began between two days and ten weeks of life. at onset it is associated with: myoclonic jerks, partial fits and periodic paroxysmal EEG abnormalities[semanticscholar.org]

  • Generalized Clonic or Tonic-Clonic Seizures

    myoclonic jerks of cortical origin.[mendelian.co] Other information is obtained from tests such as: EEG (electroencephalogram) : people with EGTCS have normal EEG background and generalized spike wave or polyspike wave activity[epilepsy.com] Generalized myoclonic-tonic-clonic seizures begin with a few myoclonic jerks followed by tonic-clonic activity.[medlink.com]
