1. Trauma is COMMON.
60% of adults and 40% of children report at least one traumatic experience during childhood. If we add in community, structural and historical adversity, prevalence of trauma is much higher.
2. Trauma DISRUPTS Brain-Body Regulation
This disruption can cause inflammation and trigger chronic disease.
3. Most Trauma is COMPLEX and DOSE-DEPENDENT
Most trauma is not from a “single-event” – but patterns of recurrent trauma. The more trauma a person experiences (the higher the DOSE), the higher their likelihood of resulting physiologic Brain-Body Dysregulation - and physical or emotional illness.
4. Impact of trauma depends on underlying state of emotional and physical regulation (balance) and
the presence or absence of supportive factors which "buffer" the traumatic impact.
5. People seeking medical care have a high likelihood of Trauma.
6. Trauma is preventable and can heal.
COMPLEX TRAUMA – multiple, chronic or recurrent traumatic experiences AND the wide-ranging and long term impact of these experiences. COMPLEX TRAUMA usually has its origins in childhood and occurs in an interpersonal context.
COMPLEX TRAUMA can have devastating impact on:
o Brain-Body Regulation
o Emotional Regulation and mental suffering
o Physical illness
o Early death (premature mortality)
Developmental Trauma – occurs during early life or critical developmental periods and results in delayed or abnormal development of Brain Networks.
o Inadequate attentive care, touch, and co-regulation during child development
o Disruption in Parent-Child Attachment
o Child Maltreatment – Interpersonal Victimization (physical, emotional, sexual abuse)
o Chaotic Home Environment; Family Violence
o Severe separation anxiety
o Loss of trust - of family members, other people, public agencies (police, healthcare, etc)
o Negative self-image
o Risk of self-harm or suicide
o Expecting to die early (foreshortened future)
o Difficulty in protecting oneself including challenges in assessing other people and their motives - often leading to re-victimization
CLINICAL APPLICATION: Many researchers and clinicians have advocated for years that Developmental Trauma Disorder be formally recognized as an appropriate clinical diagnosis for children with complex trauma - and for adults with severe childhood adversity. As well documented in the lay and academic press, when the American Psychiatric Association (APA) revised the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 2013, the diagnosis of Developmental Trauma was excluded.
Research has continued to demonstrate the critical importance of the concept of Developmental Trauma - and that the impact of Developmental Trauma extends beyond PTSD.

Eur J Psychotraumatol. Results of 271 structured interviews with children (aged 8-18) demonstrated that children with PTSD and Developmental Trauma both suffered from separation anxiety and suicidality but only the children with Developmental Trauma additionally suffered from depression and oppositional defiant disorder.

o Trauma passed unintentionally from one generation to the next.
o Descendents of a person who has experienced trauma may show adverse emotional and behavioral reactions that are similar to their family even though they did not directly experience the trauma themselves.
o Many traits that were thought to be “genetic” because they were found to “run in families” are now recognized as the result of Intergenerational Trauma.

o A person’s life experience of daily trauma from discrimination – such as daily discrimination on the basis of race, gender, sexual orientation,
o Intersectional Discrimination is the complex cumulative way that one person or group may experience multiple types of discrimination (such as race+gender+class)
o Emotional damage from inequity enforced through public policies, institutional practices, cultural images, and behaviors which are built into the structure of the culture, and
which reinforce social inequity.
o May have occurred in the past AND may continue to the present
o. Through intergenerational and secondary trauma, descendents of those who directly experienced historical trauma (slavery, war, etc), may have similar adverse emotional and behavioral reactions even though they did not directly experience the trauma themselves
Violence by individuals - against other individuals - includes emotional, verbal, physical and sexual abuse.
Tragically, although the news media often focus on public shootings, most violence against individuals (children or adults) occurs in the home.
Violence can occur at any time in life, but the most devastating impact is violence endured as children. Perpetrators of violence against children are most often parents, other caregivers, siblings, or friends of the family.
Traumatic violence affects development and function of brain networks and of emotional regulation. Experiencing violence during child development is closely tied to subsequent mental and physical illness, often appearing in adolescence or early adulthood. Violence during childhood is also tied to adolescent-adult addiction, risky sexual behavior, and involvement with law enforcement.
The impact of Trauma (and the intensity of the Acute Stress Response) is proportional to the level of perceived threat and personal traumatic experience - rather than what others might think. Two people can experience the same situation and have different stress reactions to the same event.
o Although we have been trained to recognize and report physical signs of abuse, most trauma goes unreported and unrecognized.
o Prevention, identification and treatment of TRAUMA require a solid foundation of knowledge about trauma and its effects, skill in recognizing signs of trauma and sensitive inquiry.

o Estimates are that at least 4 Milllion US children are abused each year
o Most victims experience abuse and neglect throughout childhood, often starting under age 18 months. Abuse occurs across all socioeconomic levels, ethnic and cultural lines, religions and educational levels
o Sexual abuse in children: 35% of girls and 20% of boys under age 18

Quagliato (2021) Physical abuse during childhood predicts IL-2R levels in adult panic disorder patients. J Affect Disord. Childhood maltreatment confers high risk of adult mental disease. However the biological mechanisms have not completely understood. Dysregulation of the immune system is thought to be key. By evaluating levels of inflammatory markers of ADULTS, comparing 84 patients with Panic Disorder to 78 healthy matched controls, researchers demonstrated that childhood trauma contributes to a pro-inflammatory state in adulthood.

SINGLE-EVENT TRAUMA is a specific event - with a clear beginning and end - such as a robbery, an explosion, a car accident.
A Single-Event Trauma can have enduring effects. The impact (emotional and physiological) of a single-event trauma depends on the person's underlying state of emotional and physical regulation (balance) and the presence or absence of supportive factors which "buffer" the traumatic impact.
Most trauma is NOT single-event - but is a component of COMPLEX TRAUMA.
ACCULTURATION TRAUMA is the emotional distress from difficult transition to a new culture (usually as part of immigration). Acculturation is a major root cause of Cumulative-Complex Trauma for all immigrants - and is often unrecognized by healthcare.
ACCULTURATION is the process of learning and incorporating the values, language, customs of a new culture. Acculturation can benefit all immigrants to gain access to resources, leave harmful situations, and make new connections. However, acculturation can also be traumatic.
ACCULTURATION can be TRAUMATIC if immigrants feel they are losing their own culture, identity, and sense of community. Often immigrants have experienced abuse and violence in their home country and hoped to have a better life in a new country. But their experience in the new country may not be what they hoped - as they face new barriers including discrimination and lack of access to basic resources. Acculturation is often easier for 2nd generation immigrants but can lead to family discord if older generations feel youth have forgotten their home language and culture.
NOTE: although Acculturation usually is applied to the experience of Immigrants, Acculturation challenges apply to anyone who is shifting in-out of any other culture - for example joining the Military which has a significantly different culture than civilian life; leaving home to attend a boarding school or college; joining a new work environment, etc.

Secondary Trauma is from witnessing or hearing about trauma that others have experienced. Secondary Trauma is a major cause of BURNOUT.
First Responders (doctors, nurses, EMT, police, fire, and more) are exposed to Secondary Trauma every day. Teachers, Social Workers, Psychologists and other helping professions are also at great risk. Soldiers in combat, who may not be directly injured, are often deeply affected if they witness their team members or civilians being hurt.
The impact of Trauma depends on:
o the person’s stage of development, and
o the frequency, severity, and duration of the Trauma, and
o the person’s resources to buffer the trauma (emotional, physical, and most importantly relational resources)
