“…At extremely low GA low frequencies represent about 90% of the EEG traces, while, with maturation of cortical circuitry, theta gradually replace delta activity and alpha and beta activity also increase [5,6,28,30,31].…”

“…The electrophysiological tools have the advantage over imaging techniques of being less expensive and available at the bedside. Abnormal developmental trajectories of early prematurity could be detected as early as 35 weeks post-conception, both using event-related potentials [25][26][27] and quantitative EEG [28][29][30].…”

Prematurity is a prototype of biological risk that could affect the late neurocognitive outcome; however, the condition itself remains a non-specific marker. This longitudinal 6-year study aimed to evaluate the prognostic role of neonatal spectral EEG in premature infants without neurological complications. The study cohort was 26 children born 23–34 gestational ages; all neonates underwent multichannel EEG recordings at 35 weeks post-conception. EEG data were transformed into the frequency domain and divided into delta (0.5–4 Hz), theta (5–7 Hz), alpha (8–13 Hz), and beta (14–20 Hz) frequency bands. At 6 years, a neuropsychological and behavioral evaluation was performed. Correlations between spectral bands and neuropsychological assessments were performed with a conservative and robust Bayesian correlation model using weakly informative priors. The correlation of neuropsychological tasks to spectral frequency bands highlighted a significant association with visual and auditory attention tests. The performance on the same tests appears to be mainly impaired. Conclusions: We found that spectral EEG frequencies are independent predictors of performance in attention tasks. We hypothesized that spectral EEG might reflect early circuitries’ imbalance in the reticular ascending system and cumulative effect on ongoing development, pointing to the importance of early prognostic instruments. What is Known:• Prematurity is a non-specific marker of late neurocognitive risk.• Precise prognostic instruments are lacking, mostly in patients with low-grade conditions.What is New:• Longitudinal long-term studies are scarce but crucial for the inferential attributive process.• Spectral EEG frequencies are independent predictors of performance in attention tasks.

“…A two-channel EEG device has been used to explore spectral information with high accuracy in the human brain. [1][2][3][4] It has been reported that EEG activity change is associated with psychiatric disorders. [5][6][7][8][9][10][11] Lee et al reported that the functional connectivity of beta frequency was decreased in patients with post-traumatic stress disorder (PTSD) compared to healthy controls, and beta connectivity was correlated with PTSD symptoms.…”

This study suggests that increased beta power, reflecting the psychopathology in the bereaved families of the Sewol ferry disaster, may be a compensatory mechanism that follows complex trauma. Frontal beta power could be a potential marker indicating the severity of sleep disturbances. Our results suggest that sleep disturbance is an important symptom in family members of the Sewol ferry disaster's victims, which may be screened by EEG beta power.
