  1. National Brain Bank: Essential for suicide prevention Jill M. Harkavy-Friedman, PhD Advocacy Forum 2014 Washington, DC

  2. Learning from the brain • Suicide is related to brain structure and function • Specific parts of the brain relate to suicide • Brain chemicals relate to suicidal behavior • Gene expression in the brain is different for those who die by suicide • Suicidal people make decisions differently • Medications that affect brain chemicals can reduce suicide

  3. AFSP & Brain function • Victoria Arango 1990-present (Columbia University) • Post-mortem brain studies showed: • Serotonin, a neurotransmitter associated with depression and impulsivity, was decreased in the frontal cortex, the part of the brain that controls and manages our decision making. • People with depression who died by suicide had more, rather than fewer, serotonin neurons in the dorsal raphe nucleus

  4. Genetics of the brain • Gustavo Turecki 2000’s(SRG; McGill Univeristy) • Post-mortem brain studies showed: • In the frontal cortex, the gene TrkB-T1 presents at lower rates in those who died by suicide than in others.  • The frontal cortex is involved in the organization and inhibition of behavior, and lowered functioning has been found to relate to rigid thinking and impulsiveness. 

  5. Brain in action • Jeff Bridge (YIG; Ohio State University) • Demonstrated that rigid thinking, impulsive behavior and poor decision-making was elevated in adolescents who had made suicide attempts. • Hillary Blumberg (SRG; Yale University) • Decrease in frontal white matter integrity in adolescents with depression who made suicide attempts. • Anthony Ruocco (YIG; U of Toronto Scarborough) • Testing the effect of DBT on brain function

  6. A National Brain Bank • Strength in numbers • Standardization • Accessibility • Longevity • Innovation

  7. A National Brain bank can save lives Learn more about AFSP research at www.afsp.org
