Insights
Children orphaned by HIV/AIDS show altered brain activity, specifically increased theta and decreased beta waves. This altered resting-state brain oscillation correlates with behavioral issues, suggesting potential as diagnostic indicators.
Area of Science:
- Neuroscience
- Pediatric Psychology
- Neurodevelopmental Disorders
Background:
- Early life adverse events, such as parental HIV/AIDS, can impact child brain development.
- Limited data exists on resting-state brain activity in children orphaned by HIV/AIDS.
Purpose of the Study:
- To investigate resting-state brain oscillations in children orphaned by HIV/AIDS using electroencephalography (EEG).
- To explore correlations between EEG findings and behavioral assessments.
Main Methods:
- Utilized resting-state EEG data from 90 children (aged 9-17) orphaned by AIDS and 66 controls.
- Included 63 orphans and 65 controls with EEG data and Teacher-Child Rating Scale (T-CRS) scores.
- Analyzed theta and beta wave activity and the theta/beta power ratio.
Main Results:
- Children orphaned by HIV/AIDS exhibited increased midline theta activity and decreased left hemisphere beta activity.
- A higher overall theta/beta power ratio was observed in the orphan group.
- The theta/beta ratio positively correlated with learning problems and acting out behaviors, and negatively with task orientation and social skills.
Conclusions:
- Children orphaned by HIV/AIDS demonstrate distinct resting-state brain activity compared to controls.
- EEG-based brain oscillation patterns may serve as indicators for behavioral problems in this population.
Abstract:
Early life adverse events in children orphaned by parental HIV/AIDS can have long-lasting effects on brain function. However, data are limited regarding the brain activation during resting state in these children. The current study aims to investigate the brain oscillation at rest in children orphaned by HIV/AIDS using resting-state EEG data. Data were derived from a larger neurodevelopmental study in which 90 children aged 9-17 years orphaned by AIDS and 66 matched controls were recruited through the local communities and school system. Children (63 orphans and 65 controls) who had resting-state EEG data and completed the Teacher-Child Rating Scale (T-CRS) were included in the current analysis. EEG results showed that children orphaned by HIV/AIDS had increased theta activity in the midline region, decreased beta activity in left hemisphere and overall increased theta/beta power ratio. Furthermore, the theta/beta ratio is positively correlated with learning problem and acting out scores, and negatively correlated with task orientation and peer social skill activities. Findings support that children orphaned by HIV/AIDS demonstrate different brain activity compared to non-orphan controls and also suggest that the EEG activities in resting state may serve as useful indicators of children's behavioral problems.
