Jason Jones and researchers in Philadelphia have studied a subsample of participants from the Philadelphia Neurodevelopmental Cohort to understand whether neurocognitive functioning is associated with a family history of a suicide attempt.
Jones et al. matched 501 participants (aged 8-21 years) who had a family history of a suicide attempt with ~3,000 participants with no such family history. They then compared measures of neurocognitive function between the two groups.
Those with a family history of a suicide attempt exhibited poorer executive function, attention and language reasoning than those with no family history. The researchers thus consider that further studies are now warranted to investigate whether neurocognitive deficits might serve as an endophenotype for suicide risk. If so, neurocognitive functioning could potentially be targeted in interventions to prevent or treat suicidal behaviours in at-risk youth.
