# What Are Adverse Childhood Experiences (ACEs)?
ACEs stands for adverse childhood experiences. This term emerged from a landmark study examining how difficult childhood events shape long-term health outcomes. Parents encounter this concept frequently when discussions turn to understanding a child's ACE score.
The original research came from a collaboration between the CDC and Kaiser Permanente in the 1990s. Researchers tracked thousands of adults and connected their childhood experiences to physical and mental health conditions decades later. The study identified ten categories of adverse experiences: physical abuse, emotional abuse, sexual abuse, physical neglect, emotional neglect, parental substance abuse, parental mental illness, parental incarceration, parental divorce, and domestic violence.
Each experience counts as one point. A higher ACE score correlates with increased risk for conditions like heart disease, diabetes, obesity, depression, and substance abuse in adulthood. The research shows that stress from adversity literally changes how a child's brain and body develop.
Understanding ACEs helps parents recognize that children exposed to hardship face real health vulnerabilities. This isn't about blame. Many parents experience trauma themselves and pass stress responses to their children unknowingly. The science reveals how adversity compounds across generations.
However, ACEs tell only part of the story. Resilience factors matter enormously. Children with strong relationships, access to mental health care, stable housing, and trusted adults in their lives show better outcomes despite high ACE scores. This research has shifted focus from just measuring harm to building protective factors.
For parents, the takeaway is this: if your family experienced difficult circumstances, your child isn't destined for poor health outcomes. Healing matters. Connection matters. Getting support for yourself and your child creates real change. Many communities now screen for ACEs and connect families to resources like therapy, parenting classes, and social services.
