138 Possible Causes for Myoclonic Jerking, Nocturnal Seizure, Spike-and-Slow-Waves

  • 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] EEG showed long sequences of slow spike-wave activity and half the patients had spike and slow wave foci.[ncbi.nlm.nih.gov] In one half of these patients with poor outcomes, repeated minor epileptic status and nocturnal generalized tonic seizures persisted.[ncbi.nlm.nih.gov]

  • Epilepsy

  • 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] spike and slow wave pattern of 1.5 to 2 Hz, [and it has] different seizure types.[neurologylive.com] Thirty out of 57 (53%) recently had nocturnal seizures.[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] The spike-peak and slow-wave onset phases did not show a consistently dominant outflow region.[ncbi.nlm.nih.gov] There are repeated seizures (nocturnal seizures), especially in the waking hours of the morning, which can sometimes be due to awakening earlier than usual or due to insufficient[medindia.net]

  • 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] […] and slow wave seen in at least 85% of slow-wave sleep.  Characterized by a hallmark EEG presentation, called continuous spike and-wave during sleep (CSWS) or electrical[slideshare.net] Most nocturnal seizures occur in stage 1 and stage 2 , which are moments of lighter sleep. Nocturnal seizures can also occur upon waking.[healthline.com]

  • Idiopathic Generalized Epilepsy

    Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[annalsofian.org] Nocturnal epilepsy Progressive myoclonic epilepsy Reflex epilepsy Secondary reading epilepsy Seizure, myoclonic Seizures, myoclonic Severe myoclonic epilepsy in infancy Stress-induced[icd9data.com] Myoclonic-astatic seizures consist of symmetric myoclonic jerks followed by periods of absent muscle tone that can result in falls.[symptoma.com]

  • Familial Progressive Myoclonic Epilepsy

    jerks may occur as a component of an absence seizure or at the onset of a GTCS Early Infantile Myoclonic Encephalopathy (Otohara Syndrome) General features: Initial seizures[neurodiffdx.com] Childhood AD: Autosomal Dominant BFIS: Benign Familial Infantile Seizures BFNC: Benign Familial Neonatal Convulsions CSE: Convulsive Status Epilepticus CSWS: Continuous spike-and-waves[amplexa.com] […] infancy Familial Frontal lobe epilepsies (Autosomal Dominant Nocturnal Familial Frontal lobe Epilepsy) Familial Mesial Temporal lobe epilepsies Familial Lateral Temporal[swedish.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] waves.  Within 1 year, EEG - abnormal slow BG with frequent asymmetrical paroxysms of polyspikes or spikes-slow waves.  Ictal EEG  Varies according to seizure type. 16[slideshare.net] Nocturnal epilepsy Progressive myoclonic epilepsy Reflex epilepsy Secondary reading epilepsy Seizure, myoclonic Seizures, myoclonic Severe myoclonic epilepsy in infancy Stress-induced[icd9data.com]

  • 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] FBM therapy induced disappearance of the EEG ictal slow, spike and wave complexes leaving rather unaffected the runs of spikes.[ncbi.nlm.nih.gov] Tonic; atonic and atypical absences Myoclonic, atonic and myoclonic-atonic Tonic seizures Common and characteristic, diurnal and nocturnal Probably exclusion criterion (nocturnal[icnapedia.org]

  • Absence Seizure

    […] seizures), and juvenile myoclonic epilepsy (JME; generalised syndrome characterised by myoclonic jerks, generalised tonic-clonic seizures, and, less commonly, absence seizures[bestpractice.bmj.com] The onset may be difficult to discern, and postictal EEG slowing may be noted. Slow spike-and-wave discharges (2.5 Hz).[emedicine.com] An 11-year-old girl had nocturnal motor seizures, beginning at the age of 7 years.[ncbi.nlm.nih.gov]
