308 Possible Causes for 3-4 Hz Spikes, Polyspike-and-Slow-Waves, 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] Interictal The background EEG is often highly disorganized with high voltage irregular slow waves intermixed with multifocal spikes and polyspikes, this is termed 'hypsarrhythmia[epilepsydiagnosis.org] 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]
