267 Possible Causes for 3-4 Hz Spikes, 3-6 Hz Polyspikes, Urine Organic Acids Abnormal

  • West Syndrome

    Urine organic acids, amino acids and serum biotinidase are done. CT or MRI scan of the brain is done before the treatment is started.[epainassist.com] In majority of the cases, abnormalities are found. EEG is a vital test, which is done to find out hypsarrhythmia, as this is crucial to the diagnosis.[epainassist.com]

  • Juvenile Myoclonic Epilepsy

    Interictal electroencephalography (EEG) displays 3-6 Hz spike/polyspike and wave pattern. Photosensitivity is common.[ncbi.nlm.nih.gov] Interictal electroencephalography (EEG) in JME shows interictal epileptiform discharges such as generalized spikes, polyspikes, bilateral-synchronous 4-6/s spike-wave complexes[go.galegroup.com] The EEG in untreated individuals is typically abnormal with what is known as a 3-6 Hz generalized polyspike and wave discharge.[epilepsy.com]

  • 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] Childhood absence epilepsy with tonic-clonic seizures and electroencephalogram 3-4-Hz spike and multispike-slow wave complexes: linkage to chromosome 8q24.[reference.medscape.com] Her EEG showed 34 Hz spike and wave discharges. She had a daughter with childhood absence epilepsy, and two sisters and a cousin with seizures (fig 2 , family 1).[jnnp.bmj.com]

    An EEG in untreated individuals is typically abnormal with a specific EEG pattern, known as a 3-6 Hz generalized polyspike and wave discharge.[epilepsy.com] Diagnostic methods Diagnosis relies on the clinical features and on electroencephalogram (EEG) recorded awake and during sleep, that displays a generalized 3-4 Hz spike-and-slow-wave[orpha.net] 5 Hz polyspikes and waves with frontocentral predominance Interictal EEG : 4–6 Hz bilateral polyspike and slow wave Responds well to antiseizure drug therapy; seizures become[amboss.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    The EEG shows generalised spike and wave discharges of 3 to 4 Hz and some with photic sensitivity. This is potentially a lifelong epilepsy.[pennsw.com.au]

  • Early Infantile Epileptic Encephalopathy Type 3

    Epileptic encephalopathy with suppression-burst in electroencephalography (EEG) can evolve into a few types of epileptic syndromes. We present here an unusual case of early myoclonic encephalopathy that evolved into migrating partial seizures in infancy. A female neonate initially had erratic myoclonus movements,[…][ncbi.nlm.nih.gov]
