In a normal 28-week pre-term infant, the EEG should show which type of pattern?

• A. Hypsarrythmia
• B. Vertex waves and sleep spindles
• C. Trace discontinu
• D. Hypnagogic hypersynchrony

Answer: (C)

In a normal 28-week pre-term infant, the EEG typically exhibits a pattern known as trace discontinu. This pattern is characterized by intermittent bursts of brain activity followed by periods of relative silence, reflecting the developmental stage of the infant's brain at this gestational age. Trace discontinu demonstrates the immaturity of the brain, which is common in pre-term infants, as their neural connections and patterns are still developing. As the infant matures, the EEG patterns will evolve, eventually showing more organized and rhythmic activity such as sleep spindles and vertex waves, which are observed in more developed infants and children. This progression is important for monitoring the neurological development of pre-term infants. Trace discontinu is an expected finding in this population and serves as a reference point for assessing brain maturation and the potential need for further investigation if atypical patterns are noted.
