1,548 Possible Causes for Lower and Upper Limbs Affected, Myoclonic Jerking, Polyspike on Photic Stimulation

  • Benign Adult Familial Myoclonic Epilepsy

    Photic stimulation and hyperventilation were performed in all. RESULTS: Nineteen (eight men, 11 women) patients with BAFME were included in this study.[ncbi.nlm.nih.gov] 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]

  • 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] Two cases of juvenile myoclonic epilepsy (JME) presented with myoclonic jerks and EEG activation after eye closure, without sensitivity to intermittent photic stimulation.[ncbi.nlm.nih.gov] These discharges may be evoked by photic stimulation (blinking lights) and/or hyperventilation.[en.wikipedia.org]

  • 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] Photic stimulation may trigger generalised spike/wave or myoclonic astatic seizures.[pennsw.com.au] 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] These discharges are often precipitated by hyperventilation, sleep deprivation, and intermittent photic stimulation (IPS).[epilepsy.com] This epilepsy is characterized by absence seizures concurrent with myoclonic jerks, typically occurring several times daily.[en.wikipedia.org]

  • Epilepsy

    So the jerks were considered as cortical origin and generalized myoclonic seizure was confirmed.[ncbi.nlm.nih.gov] GTCS generalized tonic-clonic seizures; TCS tonic-clonic seizures; T tonic; A atonic; H hemiclonic; abs absence; MJ myoclonic jerks; PSSG partial seizures, secondarily generalized[brain.oxfordjournals.org] People with JME can have absence seizures, myoclonic (muscle-jerking) seizures, and generalized tonic-clonic seizures.[everydayhealth.com]

  • Familial Infantile Myoclonic Epilepsy

    One fifth of patients have photosensitivity, with myoclonic jerks precipitated by photic stimulation.[medlink.com] […] wave in burst or isolation  Photic stimulation 40%  Theta rhythm of 5-6Hz in central and vertex 95% 43. 17 m. child with SW induced by opening and closing eyelids Recurrence[slideshare.net] Photic stimulation may also be a trigger. The EEG is abnormal in most untreated patients showing 4–6-Hz generalized atypical polyspike-and-wave discharges.[neupsykey.com]

  • Unverricht-Lundborg Syndrome

    The myoclonic jerks occur in the muscles of the arms and legs closest to the torso, and are triggered due to a variety of common external stimuli. [7] Seizures begin at an[en.wikipedia.org] There are generalized polyspike discharges at rest that are exacerbated by photic stimulation. Fig. 2 EEG of individual V-13 at age 35 years.[academic.oup.com] Treatment with different neuroleptics led to an increase of the myoclonic jerks. Sleep deprivation also led to an increase in myoclonic jerks.[frontiersin.org]

  • 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]

  • 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] 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] [[sturge_weber_center]] Juvenile Myoclonic Epilepsy People with juvenile myoclonic epilepsy (JME) have myoclonic seizures, characterized by small, rapid jerks of the arms,[hopkinsmedicine.org]
