2 Possible Causes for 2.5-3.5 Hz Spike-and-Slow-Waves

  • Neonatal Seizures

    Herein we report a case of a male infant with hyperekplexia. He was born after an uneventful pregnancy to healthy unrelated parents. At 2 days, he began to have frequent episodes of apnea accompanied with generalized tonic posture. Phenobarbital had been prescribed for the suspicion of neonatal seizures.[…][ncbi.nlm.nih.gov]

  • Idiopathic Hemiconvulsion-Hemiplegia Syndrome

    The discharge is initially 3.5—4 Hz, but slows down to 2.5—3 Hz (12). Each spike-wave complex contains one or two (or rarely three) spikes and a slow wave.[aibolita.com]
