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.[] The EEG shows generalized polyspike and spike-and-wave discharges, frequently precipitated by photic stimulation.[] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[]

  • 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.[] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[] 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.[]

  • Juvenile Myoclonic Epilepsy

    The myoclonic jerks occur rarely in EMA. They are usually mild and are freqently restricted to the upper extremities.[] spike-polyspike and waves.[] All of these patients were contacted and asked specifically about myoclonic jerks.[]

    Missing: Lower and Upper Limbs Affected
  • Epilepsy

    So the jerks were considered as cortical origin and generalized myoclonic seizure was confirmed.[] spike wave and polyspike wave activity.[] People with JME can have absence seizures, myoclonic (muscle-jerking) seizures, and generalized tonic-clonic seizures.[]

    Missing: Lower and Upper Limbs Affected
  • Myoclonic-Astatic Epilepsy

    The involvement of these structures might predispose to the typical seizure semiology of myoclonic jerks observed in MAE.[] […] 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[] jerks, by using burst-locked EEG averaging where necessary.[]

  • Idiopathic Generalized Epilepsy

    Myoclonic-astatic seizures consist of symmetric myoclonic jerks followed by periods of absent muscle tone that can result in falls.[] Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[] The abnormalities included generalized spike-wave and/or spike-polyspike morphology in majority.[]

  • Familial Infantile Myoclonic Epilepsy

    One fifth of patients have photosensitivity, with myoclonic jerks precipitated by photic stimulation.[] The EEG shows a normal background with 3.5–4-Hz generalized spike–wave discharge, at times polyspike and wave.[] 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[]

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

  • Early Infantile Epileptic Encephalopathy Type 3

    Both patients had early infantile seizures characterized by fragmentary myoclonic jerks associated with burst-suppression pattern on electroencephalography.[] Early Myoclonic Encephalopathy starts in the first 10 days of an infant’s life with erratic small jerks (i.e. myoclonic seizures).[] […] 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[]

  • Generalized Clonic or Tonic-Clonic Seizures

    myoclonic jerks of cortical origin.[] 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[] Generalized myoclonic-tonic-clonic seizures begin with a few myoclonic jerks followed by tonic-clonic activity.[]
