124 Possible Causes for 3-6 Hz Polyspikes, Jerk-Locked Premyoclonus Spikes, Progressive Action Tremor

  • Benign Adult Familial Myoclonic Epilepsy

    Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture.[uniprot.org] […] cortical spikes detected by the jerk-locked back-averaging) ( Ikeda et al., 1990 ).[academic.oup.com] The EEG reveals 4 to 6 Hz bilateral symmetric polyspike-wave complexes or 2-3 Hz spike wave complexes. Photosensitivity is common ( 70%).[neuroweb.us]

  • Juvenile Myoclonic Epilepsy

    Interictal electroencephalography (EEG) displays 3-6 Hz spike/polyspike and wave pattern. Photosensitivity is common.[ncbi.nlm.nih.gov] The EEG in untreated individuals is typically abnormal with what is known as a 3-6 Hz generalized polyspike and wave discharge.[epilepsy.com] Class II criteria: Myoclonic jerks that occur mainly after awakening; Age of onset – 6 to 25 years; EEG abnormalities ( 3-6 Hz) with or without myoclonic jerks.[medindia.net]

  • Epilepsy

    Contemporary drug therapy fails to control epileptic seizures in some 30% of patients, resulting in the need to employ other measures when they appear practicable. A good deal of potentially relevant statistical detail is available regarding the outcomes of the available antiepileptic therapies, but its interpretation[…][oadoi.org]

    Massage therapists may be the first to witness their clients’ myoclonic symptoms. Bodyworkers able to differentiate between muscle spasms, harmless twitches and pathological body jerks will know when to refer their clients for a neurological evaluation.
