Fact Sheet published via downloadable pdf produced by Mental Health America (MHA), the nations leading community-based mental health non-profit.

What is Trauma?

The American Psychiatric Association’s Diagnostic and Statistical Manual (DSM-IV) defines a “traumatic event” as one in which a person experiences, witnesses, or is confronted with actual or threatened death or serious injury, or threat to the physical integrity of oneself or others.

Trauma is a public health issue that happens as a result of physical, sexual, or emotional abuse, neglect, violence, war, loss, disaster, and other emotionally harmful experiences. Like individuals, communities at large can be traumatized as well.

While many people who experience a traumatic event are able to move on with their lives without lasting negative effects, others may have more difficulty managing their trauma responses. Trauma can have a devastating impact on physical, emotional, and mental well-being.

How Does Trauma Affect Survivors?

Trauma affects the developing brain and body and alters the body’s stress response mechanisms. Emerging research documents the relationship between traumatic events, impaired brain function, and immune system responses. Trauma induces powerlessness, fear, hopelessness, and a constant state of alert, as well as feelings of shame, guilt, rage, isolation, and disconnection.

Unresolved trauma can manifest in a variety of ways including:

  • anxiety disorders

  • panic attacks

  • intrusive memories (flashbacks)

  • obsessive-compulsive behaviors

  • post-traumatic stress disorder PTSD

  • addictions

  • self-injury

Trauma increases health-risk behaviors such as overeating, smoking, drinking, and risky sex. Trauma survivors can become perpetrators themselves.

Unaddressed trauma can significantly increase the risk of mental and substance use disorders, suicide, chronic physical ailments, as well as premature death.

A New Understanding of Trauma

Until recently, trauma survivors were largely unrecognized by the formal treatment system. The costs of trauma and its aftermath to victims and society have not been well documented. Because of this, treatment systems may have frequently re-traumatized individuals and failed to understand the impact of traumatic experiences on general and mental health.

Today, the causes of trauma—sexual abuse, violence in families and neighborhoods, and the impact of war, for example—are matters of public concern. Trauma survivors have formed self-help groups to heal together. Researchers have learned how trauma changes the brain and alters behavior. A movement for trauma-informed care has emerged to ensure that trauma is recognized and treated and that survivors are not re-victimized when they seek care.

Facts at a Glance

The Adverse Childhood Experiences (ACE) Study, an observational study of the relationship between trauma in early childhood and morbidity, disability, and mortality in the United States, demonstrated that trauma and other adverse experiences in are associated with lifelong problems in behavioral health and general health.

More than 6 in 10 U.S. youth have been exposed to violence within the past year, including witnessing violence, assault with a weapon, sexual victimization, child maltreatment, and dating violence. Nearly 1 in 10 was injured.

Predicted cost to the health care system from interpersonal violence and abuse ranges between $333 billion and $750 billion annually or nearly 17% to 37.5% of total health care expenditures.
