831 Possible Causes for Myoclonic Jerking, Onset of Disease between 25 and 40 Years of Age, 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] Celiac disease (or gluten sensitive enteropathy): The age of onset may vary between 40 - 80 years and the mean duration of ataxia between 3 to 25 years.[neuroweb.us] […] 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]

  • 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] slow wave discharges.[en.wikipedia.org] The EEG typically shows a characteristic pattern with generalized 4–6 Hz polyspike and slow wave discharges .[medindia.net]

    ., 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] Ictal EEG : The myoclonic component is associated with a generalized spike or polyspike. The atonic component is associated with the aftergoing high voltage slow wave.[medlink.com] When falling asleep, it is common for people to experience a type of myoclonic jerk known as a hypnic jerk.[house.wikia.com]

    A total of 33 patients (47%) also had myoclonic jerks with a mean age at onset of 16 years.[medlink.com] The EEG has generalized spike or polyspike slow-wave complexes. JAE is a lifelong disorder, although seizures can be controlled in 70% to 80% of patients.[pennsw.com.au] […] 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]
