EEG spectra in children aged 8, 9 and 10 years. Reference values

Area of Science:

• Neuroscience
• Pediatric Neurology
• Biomedical Engineering

Background:

• Establishing normative electroencephalogram (EEG) data is crucial for identifying developmental variations in children.
• Previous research has focused on specific age groups, necessitating broader reference ranges for pediatric populations.
• Understanding brain activity patterns in healthy children provides a baseline for clinical assessments.

Purpose of the Study:

• To determine reference values for power density distribution in the electroencephalogram (EEG) of normal children.
• To analyze EEG power spectra across four distinct brain regions in children aged 8, 9, and 10 years.
• To provide a normative dataset for pediatric EEG analysis.

Main Methods:

• Electroencephalogram (EEG) recordings of 100-second duration were analyzed.
• Power density spectra were calculated for four different brain regions.
• Participants underwent comprehensive medical and psychological examinations to confirm normality.

Main Results:

• Reference values for power density distribution were established for children aged 8 to 10.5 years.
• Analysis revealed specific power density patterns across the studied brain regions in the pediatric cohort.
• Normative data were generated based on a rigorously screened group of healthy children.

Conclusions:

• The study successfully generated reference values for pediatric EEG power density spectra.
• These findings contribute essential normative data for the interpretation of EEG in children.
• The established reference values can aid in the diagnosis and monitoring of neurological conditions in children.
