247 Possible Causes for 3-6 Hz Polyspikes, Slow-Frequency High-Amplitude Waves with High-Frequency Polyspikes, Variable Psychomotor Retardation

  • Myoclonic-Astatic Epilepsy

    […] years of age; (3) presence of generalized spike- or polyspike-wave EEG discharges at 2-3 Hz, without focal spike discharges; and (4) exclusion of severe and benign myoclonic[ncbi.nlm.nih.gov] retardation mainly affecting speech.[ipfs.io] […] years; EEG findings of generalized spikes or polyspike-wave discharges at 2-3 Hz with an absence of focal spikes; Exclusion of other syndromes, specifically, cryptogenic Lennox-Gastaut[symptoma.com]

  • 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]

  • Benign Adult Familial Myoclonic Epilepsy

    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]

  • Generalized Clonic or Tonic-Clonic Seizures

    ‘Contrary to popular folk belief, nothing should be placed in the mouth during the seizure. Severe injury could occur.’ Generalized tonic clonic seizures (grand mal seizures) are the most common and best known type of generalized seizure. They begin with stiffening of the limbs (the tonic phase), followed by jerking[…][epilepsynw.org]

  • Myoclonic Jerking

    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. When a client’s body jerks on the massage table, it is natural[…][integrativehealthcare.org]
