Trauma and the Brain Andraé L. Brown, PhD, LMFT
Why Look at Trauma? • 40 to 60% of youth in foster care have
mental health problems vs. only 20% in the general population.
• Common traumatic experiences: – Abuse and severe neglect – Exposure to domestic violence – Separation from natural family
Why Look at Trauma? (cont.) • One study that looked at trauma in foster
children found PTSD in 64% of sexually abused children, 42% of physically abused children, and 18% of non-abused children.
• Trauma appears to be a chronic problem for these individuals: – PTSD in adults who were in foster care in childhood is
nearly five times higher than in the general population (22% vs. 5%).
– They may not recover from PTSD as well as the general population.
Central Nervous System (CNS) • In order to understand trauma, we need some
understanding of how the brain (and spinal cord) develops and functions. – The CNS is the primary way we process, make sense
of, and respond to threatening situations in the environment.
– The CNS mediates how we experience trauma via our senses (what we see, hear, feel, smell, or taste); how we understand the event (threatening vs. not); and what we do or don’t do in response to the event (fight-flight).
Brain Development • Several important areas of development
are dependent on the brain, including: – Social and emotional development
• Attachment – Cognitive development
• Mental activities such as thinking, language, memory
– Physical development • Growth, puberty, muscle coordination
Brain Development • Basic survival
– Brain stem and spinal cord
– Breathing, heart rate, body temperature, and sleep-wake cycles
• Reflexes and motor coordination – Cerebellum – Sucking, blinking reflexes
Brain Development (cont.) • Emotions and memories
– Limbic system • Complex brain
functions, including reasoning, planning, decision making, language, and behavioral control (develop last) – Cerebral cortex – Development continues
into young adulthood
Brain Development (cont.) • Social and emotional
development – The early caregiver-child
relationship is critical to: • Healthy brain “wiring”
(brain cell connections) • Associated with
emotional competence
Brain Development (cont.) • Social and emotional development
– Early attachments provide a context for children to learn to understand emotions and to learn to regulate them
– Early relationships teach children about: • Themselves à What am I feeling? Can I deal with
problems? Am I a good person? • Others à Can I trust others to help me? • Relationships à Do good experiences come from
being close to others?
Brain Development (cont.) • Social and emotional development
– Caregivers who are sensitive and responsive to their child’s needs tend to have children who develop:
• Better emotional and behavioral control • Better language skills • Better interpersonal skills
The Adolescent Brain • The adolescent brain is
still a work in progress • The frontal lobe is still
developing (prefrontal cortex)
• This is the part of the brain responsible for: – Decision making – Planning ahead – Inhibition – Social understanding
The Adolescent Brain (cont.) • Problems seen in adolescence that result
from an immature frontal lobe (prefrontal cortex): – Making poor and impulsive decisions—not
thinking things through – Significant problems taking other people’s
perspective—being very self-oriented – Risk-taking
The Adolescent Brain (cont.) • What else is going on in there?
– Teens have a “conflict” between social- emotional networks of the brain and cognitive- control networks.
– The social-emotional networks are more active than cognitive-control networks; in the end, feelings often override logic.
Stress Response • We’re all equipped with a natural stress
response mechanism. • “Fight-flight” response:
– Stress causes certain hormones to be released in the body that prepare you to deal with a temporary “threat” (short-term response).
– After the threat has passed, the body goes back to its normal state.
– However, extreme (toxic) stress causes physical and psychological problems (traumatic experiences, constant exposure to stress for long periods of time).
Stress Response (cont.) • Prolonged exposure to stress can lead to:
– Headaches, muscle tension, pain in neck or back
– Upset stomach – Chest pains, rapid heartbeat – Difficulty falling asleep or staying asleep – Fatigue, sluggishness – Loss of appetite or overeating (“comfort
foods”) – Increased illness
Stress Response (cont.) • (continued):
– Poor concentration or focus – Memory problems, being forgetful – Feeling jittery – Irritability – Short temper – Anxiety
What’s Trauma? • Is there a difference between stress
and trauma? – Psychological trauma is a particular type
of stress – Extreme or “toxic” stress
What’s Trauma? (cont.) • Trauma “occurs when a sudden,
unexpected, overwhelming intense emotional blow or a series of blows assaults the person from outside. Traumatic events are external, but they quickly become incorporated into the mind.”
—Dr. Lenore Terr
What’s Trauma? (cont.) • We become traumatized “when both
internal and external resources are inadequate to cope with external threat.”
—Dr. Bessel van der Kolk
What’s Trauma? (cont.) • “It is not the trauma itself that does the
damage. It is how the individual’s mind and body reacts in its own unique way to the traumatic experience in combination with the unique response of the individual’s social group.”
—Dr. Sandra Bloom
Post-Traumatic Stress Disorder (PTSD)
• PTSD is the point at which trauma interferes with someone’s ability to function.
• Diagnosis of PTSD requires: – Exposure to an event that involves death, serious injury, or
the threat of extreme violation to oneself or others – Person experiences intense fear, helplessness or horror
• Other criteria: – Re-experiencing event (e.g., flashbacks, nightmares) – Avoiding anything related to the trauma – Increase in negative thoughts and feelings
Post-Traumatic Stress Disorder (PTSD) (cont.)
• Increased risk for substance/chemical misuse – Marijuana, alcohol, OTC drugs, cleaning products
• Tends to be underdiagnosed – Especially when youth have substance use problems,
very poor attention, act aggressively or violently, or have sexual behavior problems
• There is also a risk of vicarious (secondary) trauma to those working with traumatized persons
Common Traumatic Experiences • Physical, sexual, psychological abuse • Abandonment • Incest • Rape • Domestic violence • Witnessing death or severe injury • Kidnapping, hostage situations • Serious accidents • Shootings in the community • Fires • Natural disasters (e.g., Super-Storm Sandy)
Complex Trauma • Exposure to multiple traumatic events over
a long period of time • Usually beginning in early childhood • Interpersonal in nature • Disrupts development
Early Trauma • How early is “early”?
– In the womb • Intimate partner violence during pregnancy • Remember: Touch and hearing come online
before birth! – During the birth process
• Maternal stress à increased chances of birth complications
– During childhood • Target of violence directly; or exposure to violence
Early Trauma (cont.) • How does early trauma impact older
youth? – Early trauma sets the stage for problems later on. – As the child grows up, he or she attempts to
understand what happened through memories and a search for meaning—and sometimes reenactment.

Traumatized Children and Adolescents
• Behavior control problems – Reenacts traumatic experiences – Poor impulse control – Aggression – Oppositional/defiant – Excessive compliance – Sleep problems (nightmares/terrors) – Eating problems – Substance use problems
Traumatized Children and Adolescents (cont.)
• Emotional regulation problems – Poor emotional control (unable to
manage feelings) – Poor recognition of own feelings
Traumatized Children and Adolescents (cont.)
• Problems with biological and physical functioning – Anxiety – Lack of energy – Pelvic pain – Asthma – Skin problems – Problems with immune system – Bedwetting may begin or get worse
Traumatized Children and Adolescents (cont.)
• Attachment problems – Poor boundaries – Isolates self – Mistrustful – Unable to give or receive affection – Poor recognition of others’ feelings
Traumatized Children and Adolescents (cont.)
• Problems with consciousness – On “high alert” all the time (hypervigilant) – Poor alertness or being “in a fog” – Complains that things don’t seem real; dream-
like state – Memory problems (amnesia episodes)
Traumatized Children and Adolescents (cont.)
• Problems with cognition – Problems with attention – Problems completing tasks – Learning problems – Problems with language – Problems keeping track of time and place
Traumatized Children and Adolescents (cont.)
• Problems with their self-concept – Low self-esteem – Body image problems – Shame and guilt – Feelings of powerlessness or helplessness

Why Do People Respond the Way They Do to Trauma? (cont.)
• So keep in mind that when traumatized youth are triggered: – They tell themselves that they are in danger
(you or the situation becomes the threat). – They may suddenly feel intense anger, terror,
helplessness, or possibly nothing at all (auto- pilot).
– They may go into “survival mode,” which could be severe protest or fighting for their life.
Summary Points • Important points to remember when it
comes to trauma and brain development: – Brain development begins in the womb and
continues until young adulthood (early 20s). – The social environment is crucial for brain
development. – Toxic stress early on, such as trauma, may
have set the stage for what we’re seeing now in the children we serve.
