1,550 Possible Causes for Lower and Upper Limbs Affected, Myoclonic Jerking, Slowing with Polyspike-and-Slow-Waves

  • 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] […] or polyspike and slow-wave complexes.  Variable course and outcome.  One half experience encephalopathic effects and suffer from persistent GTCS, myoclonic-atonic status[slideshare.net] 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]

  • Hypoglycemia

    In newborns, hypoglycemia can produce irritability, jitters, myoclonic jerks, cyanosis, respiratory distress, apneic episodes, sweating, hypothermia, somnolence, hypotonia[en.wikipedia.org]

  • Alzheimer Disease

    After 36 hours of donepezil remission, the frequency of the myoclonic jerks was sharply reduced. The patient remains asymptomatic after 6 months of follow-up.[ncbi.nlm.nih.gov]

  • Familial Infantile Myoclonic Epilepsy

    One fifth of patients have photosensitivity, with myoclonic jerks precipitated by photic stimulation.[medlink.com] […] or polyspike and slow-wave complexes.  Variable course and outcome.  One half experience encephalopathic effects and suffer from persistent GTCS, myoclonic-atonic status[slideshare.net] […] background Irregular generalized spike or polyspike and slow wave complexes Photosensitive, decreased during sleep Prognosis: Slow progression, may live to 60s Lafora Disease[emilytam.com]

  • Epilepsy

    So the jerks were considered as cortical origin and generalized myoclonic seizure was confirmed.[ncbi.nlm.nih.gov] EEG recordings showed a variety of changes: generalized spike wave and polyspike wave activity, focal discharges, focal or diffuse slowing or were normal.[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] Atonia is usually concurrent with the slow wave of a single- or polyspike-wave complex.[medlink.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] […] and waves with frontocentral predominance Interictal EEG : 4–6 Hz bilateral polyspike and slow wave Responds well to antiseizure drug therapy; seizures become less frequent[amboss.com] Generalized spike-and-wave or polyspike-and-wave is seen in the interictal EEG. Half of the patients have these abnormalities only in sleep. Caution.[medlink.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] 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]
