Those who have a family history of bipolar disorder and have experienced traumatic stress may be at risk of suicide attempt, reports a study published in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP).
Suicide in 2015 was the second leading cause of death among teens ages 15-19 with steep increases in suicide risk from ages 14 to 20. Bipolar disorder (BD) is one of the most heritable psychiatric conditions and is associated with high suicide risk.
Bipolar Disorder
Bipolar Disorder is a brain disorder in which people show "mood swings". Changes in the level of neurotransmitters in brain, and psychosocial factors are thought to be involved.

‘Genetic susceptibility to Bipolar Disorder can increase the risk for suicide attempt, but only among those who also have experienced traumatic stress such as bullying, sexual abuse, and domestic violence.’

"We found that genetic susceptibility to BD can increase the risk for suicide attempt, but only among those who also have experienced traumatic stress such as bullying, sexual abuse, and domestic violence," said lead author Holly Wilcox, PhD, an associate professor at the Johns Hopkins Bloomberg School of Public Health.
"This work highlights the importance of severe environmental stressors in the development of suicide attempts in those at higher genetic risk for bipolar disorder."

Researchers suggest that the unquiet mind, ruminating in bipolar disorder suffers from executive dysfunction.
The findings are based on data from 307 adolescent offspring/relatives of parents affected with BD (BD-relatives) as compared to 166 offspring/relatives of parents without specific psychiatric disorders (controls).
Participants were recruited from five independent sites, four in the United States (Johns Hopkins University, University of Michigan, Washington University in St. Louis, and Indiana University) and one in Australia (University of New South Wales).
Blood samples were collected from all individuals, DNA was extracted from blood, and genome-wide genotyping was conducted. Genetic risk scores were derived from the sum of individual effects of many hundreds of BD-associated single nucleotide polymorphisms to elucidate the relative contributions of genes versus environment for suicidal behaviors in BD.
"This study uniquely examines suicidal and self-harm behaviors in a young cohort of individuals who are at increased risk of BD, but many of whom have not yet developed BD themselves," Dr. Wilcox said.
"We found that offspring of BD-relatives report more suicidal ideation and attempts than controls. This finding was sustained after accounting for the presence of mood disorders and substance use disorders, suggesting that parental BD is a key correlate of suicidal ideation and attempts, and that genetic risk for suicidal behavior is not wholly acting through a genetic pathway for mood disorder."
There were no differences between BD-relatives and controls in exposure to domestic violence, sexual abuse, being bullied, or a composite measure of any traumatic event exposure.
