Study on changes of EEG Posterior Alpha rhythm and Delta wave in healthy newborn during one year of life at tertiary care hospital

Dr. Pratibha Verma, Dr. Yogesh Shukla

Abstract :

Background: Normal electroencephalographic pattern varies with age and level of Alfa and delta activity. Sleep assessment during infancy presents an opportunity to study the impact of sleep on the maturation of the central nervous system. Objectives: – To study the changes of Posterior Alpha rhythm and slow activity delta wave in healthy newborn during one year of life. Methodology : –This longitudinal follow–up study was conducted on 50 healthy, normal, full–term newborn up to age of one year. Result :– Out of 50 newborn posterior Alpha rhythm was seen in none of the newborns at the time of 0–2 week which increased to (40/45) 88.9 % at 3 month, 88.1% (37/42) at 6 month, 94.7% (36/38) at 9 month. Slow activity delta was observed in 43/50 (86%) of newborns at 0–2 weeks, then in 40/45 (88.9 %) at 3 months and 85.7 %, 85 % and 86.8 % at 6, 9 and 12 months respectively. Conclusion: – the emerging pattern of the present study depicts the development of cereal maturation in EEG and a marked conspicuous change in Alpha and Delta rhythm in EEG.
