Clinical and neurocognitive markers of suicidality in young adults.

Suicide represents a leading cause of death in young people, yet relatively little is known regarding the neurobiological sequelae of preceding suicidal thoughts and behaviours. Although some studies have reported cognitive deficits associated with suicidality, very few studies have been undertaken in young people, especially from non-clinical contexts. Impaired decision-making exists in young people with suicidality, and may thereby predispose towards a range of suicidal thoughts and behaviours.
