# What Are Adverse Childhood Experiences (ACEs)?
Parents increasingly hear about ACEs, or adverse childhood experiences, in conversations about child development and long-term health. The concept comes from a groundbreaking 1998 study that tracked how difficult childhood events shape physical and mental health into adulthood.
ACEs include experiences like abuse, neglect, parental substance use, domestic violence, parental incarceration, or loss of a parent. Researchers assigned numerical scores based on how many ACEs a child experienced, creating what's now known as an ACE score.
The original study, conducted by Kaiser Permanente and the Centers for Disease Control and Prevention, followed thousands of adults and found a striking pattern. Each additional ACE roughly doubled the risk for certain conditions later in life. Children with four or more ACEs faced dramatically higher rates of heart disease, obesity, depression, and substance abuse as adults compared to those with no ACEs.
Understanding your child's ACE score can help parents recognize vulnerability and seek support early. Children who experience trauma benefit from stable, nurturing relationships and access to mental health services. Therapists trained in trauma-informed care can help kids process difficult experiences and build resilience.
The research also reveals something hopeful. Protective factors buffer against ACEs. Strong relationships with caring adults, secure attachment, access to quality education, and community support all reduce the long-term damage from childhood adversity. Parents don't need to erase difficult experiences from their child's life to promote healing. They need to provide consistent presence, validation, and professional help when needed.
If your child has experienced trauma, pediatricians and child psychologists can assess whether intervention helps. Organizations like the American Academy of Pediatrics now recommend screening for ACEs during routine checkups. This shift allows doctors to connect families with resources before problems compound.
