Neurocognition and academic achievement among bereaved children in the Generation R Cohort

Area of Science:

• Child Psychology
• Neurodevelopmental Science
• Public Health

Background:

• Childhood bereavement is a significant adverse event with variable health outcomes.
• Bereaved children face risks for lower educational attainment, but neurocognitive links are underexplored.

Purpose of the Study:

• To investigate the association between childhood bereavement and neurocognitive performance and academic achievement.
• To identify potential risk and resilience mechanisms in bereaved children.

Main Methods:

• Utilized data from the population-based Generation R Study (N≈10,000).
• Assessed bereavement by age 10 and cognitive function (IQ, matrix reasoning) and academic achievement at age 13.
• Employed regression analyses, adjusting for pre-bereavement factors.

Main Results:

• Bereavement by age 10 was associated with a 1.12-point lower full-scale IQ at age 13 (p=0.04), primarily due to lower matrix reasoning scores.
• No significant differences in academic achievement or other cognitive subtests were found.
• The association between bereavement and lower IQ/matrix reasoning was significant only when caregivers reported emotional impact.

Conclusions:

• Childhood bereavement can impact cognitive functions like IQ and matrix reasoning.
• Emotional impact of loss is a critical factor influencing cognitive outcomes in bereaved youth.
• Findings highlight the need for further research into risk and resilience mechanisms following childhood loss.
