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

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

Answer: (A)

In a normal 28-week pre-term infant, the EEG typically displays a trace discontinu pattern. This finding reflects the developmental stage of the infant's brain and the maturation process of the central nervous system. At this gestational age, the EEG demonstrates a lack of continuous activity, which is characteristic of a disorganized and less mature neuronal network. The trace discontinu pattern is typically seen in premature infants and indicates that the brain is still developing the capacity for more organized and rhythmic brain activity seen in older infants and full-term newborns. As the infant matures, the EEG patterns will evolve to show more organized activity, including sleep spindles and vertex waves, which represent more mature brain function associated with active sleep states. Therefore, the trace discontinu pattern is a normal finding for a 28-week preterm infant and reflects the expected EEG characteristics for that age.
