Summary
This chapter describes the spectrum of age-related maturation of electrographic patterns through preterm, neonatal, infantile, childhood, and adolescence periods. Neonatal EEGs must be interpreted in the context of corrected age and physiological state. Sustained continuity is the hallmark of maturation. Preterm records are discontinuous irrespective of state while term records are continuous in all states. Between 30 and 37 weeks, the background becomes more continuous during wakefulness and active sleep compared to quiet sleep. At term, activité moyenne is present during wakefulness and active sleep and trace alternans occurs during quiet sleep. Anterior dysrhythmia and graphoelements occur between 32 and 44 weeks corrected age. Sharp transients may be normal in neonates. A reactive posterior dominant rhythm emerges at three months of age and attains alpha range at around 2 to 3 years of age. Asynchronous sleep spindles emerge before 3 months and synchronize at 6 months of age. [144 words/855 characters]
