Hypsarrhythmia is a pattern most often associated with which condition?

• A. Atonic seizures
• B. Absence seizures
• C. Gelastic seizures
• D. Infantile spasms

Answer: (D)

Hypsarrhythmia is a distinctive EEG pattern characterized by chaotic, high-amplitude slow waves mixed with spikes and sharp waves. It is most commonly associated with infantile spasms, which is a type of seizure that typically occurs in infants. This condition is often part of a broader syndrome known as West syndrome. During the episodes of infantile spasms, the EEG may show hypsarrhythmia, which is significant for its irregularity and is indicative of a severe underlying neurological condition. Recognizing hypsarrhythmia can be crucial in diagnosing and managing infantile spasms effectively. Understanding this association helps healthcare professionals identify the pattern and respond appropriately in clinical practice.
