Exposure to traumatic events in childhood is associated with suicidal behavior in adulthood, in the form of ideas, attempted or completed suicide. The abuse causes impaired cognitive schemes in the attachment figure, abandonment, mistrust and vulnerability to damage. The literature has demonstrated the dose–response relationship between a traumatic event in childhood and the development of mental disorders and the possibility of suicidal behavior. In addition, abuse is transmitted through the generations along with another factor of suicidal vulnerability (family history of suicide). Abuse in childhood is associated with depression, anxiety, antisocial behavior or substance. In fact, in investigations is suggested the vulnerability to any psychopathological disease. A history of suicidal behavior increases the risk for these children. Since child abuse increases suicidal behavior, we can find families in which coexists history of suicidal behavior and child abuse. The high prevalence of abuse and vulnerability neurodevelopmental leads us to consider a plan of action for this population. Rejection and/or contempt suffered in a developing brain might be related to subsequent alterations in emotional regulation or impulsivity. For these associations should conduct a more thorough screening in children's consultations to address this issue. It is very important to approach about cognitive schemes that subsequently repeated dysfunctional acts. Impulsive o unstable behavior could be reduced. This would decrease the consequences that these children have in adulthood.
