Brain development has an enormous impact on our lifelong health. The experiences we have growing up change our brain architecture in ways that influence our mental and physical health. This video highlights the landmark Adverse Childhood Experience (ACE) study, which explains the relationship between ACEs and a number of health outcomes. The original ACEs study was conducted by physician and researcher, Vincent Felitti, who was Chief of Kaiser Permanente’s Department of Preventive Medicine. To demonstrate the connection between ACEs and health outcomes, Dr. Felitti developed a series of questions called the ACE Questionnaire. Researchers used this questionnaire and found a strong relationship between ACE scores and health outcomes in Alberta. Equipped with this research and an understanding of the science of brain development, we know it’s never too late to add positive supports and lighten the burden of past experiences so that people can become more resilient.
