Patterns of Atypical Hypsarrhythmia

• Asymmetrical or unilateral hypsarrhythmia
• Hypsarrhythmia with constant focal discharges
• Hypsarrhythmia comprising primary, high-voltage,

bilateral asynchronous slow activity with minimal
epileptiform potentials
• Hypsarrhythmia with partial conservation of basal
rhythm and focal or generalized sharp and slow waves
• Hypsarrhythmia similar to suppression-bursts
