Exam 1 Midterm

Masked kidnappers took school bus and abducted 26 children/bus driver ages 5-14; first group of children studied that created the consideration of PTSD in children

an uncontrollable and unpredictable event, which is beyond the score of ordinary human experience

the branch of medicine which deals with the incidence, distribution, and possible control of diseases and other factors relating to health

• Neglect

• Physical abuse

• Sexual abuse

• Natural Disasters

• Discrete (Single incident) Catastrophes

• Plus MANY more

• Disruption of healthy development

• Higher risk for emotional and behavioral problems in the present and future

• Depression

• PTSD

• Sleep Problems

• Conduct Problems

• Enuresis

• Somatization

• Eating problems

• Reactive attachment disorder

• Sexualized behaviors

• Substance abuse

• Risk-taking

Fight, Flight, and Freeze

a person who is supposed to protect you from harm, keep you safe becomes a source of alarm/danger/pain

• Tend to have lower social competence

• Often have less empathy for others

• Have greater difficulty in recognizing other's emotions

• Tend to over-read anger

• Are less able to recognize their own emotional states

• Are more likely to be insecurely attached to their parents

• Are frequently hypervigilant

• Attachment

• Emotional regulation

• Impulse control

• Integration of self

• Socialization

The more ACES (adverse childhood experiences) you have, you are more likely to have negative physical health effects

increasing ACES increased the number of problems. People with more ACES have much more higher chance of being exposed/more vulnerable to more ACES

younger

neglect

When the space challenger crashed, millions of children watched on TV live. Lenore Terr studied the geographical impact on PTSD symptoms in children.

Taught us that children might be traumatized by events that do not directly affect their personal safety of the safety of their loved ones and that closeness to the traumatic event does play a role in severity of symptoms

the development of the brain and mental processes over time; takes into account how trauma effects development and how development impacts the outcome of trauma

• Perform lower on exams/scales of intellect and academic performance

• Predictive of problems in expressive and receptive language

• More likely to be placed in special ed

• The risk of psychopathology increases dramatically

adequate nutrition, education, adequate healthcare, maternal health, and environmental health

the natural activity level, regularity, approach/withdrawal, adaptability, sensory threshold, quality of mood, intensity of reaction, distractibility, persistence and attention span of a baby/newborn

have a lot of biological regularity, have a positive approach to more new situations, easy adaptability to change, mild or moderately intense mood that is predominantly positive

negative response to new situations, slow adaptation, may have good biological regularity, and mild expressions of mood

biological irregularities, negative withdrawal from most new situations, slow adaptability to change, and intense moods that are predominantly negative

caregiver-infant behavioral system that ensures species survival

• the progression of attachment towards a primary caregiver

  • 0-8 weeks- will cry, grasp and babble

  • 2-6 months- smile clings, and visually follows

  • 6-24 months- greater range of attachment behaviors to maintain proximity: protest departure/separation, greet upon return/reunion, cling when afraid, following when able

  • Toddler uses caregiver as a "secure base" from which to explore

a caregiver in turn shows watchfulness, protective behavior, response to distress, closeness

6 and 24

the quality of care provided

measures the quality of attachment based on the reaction of a child when their primary caregiver leaves the room in an unfamiliar place (with a stranger first and then with no one), and the reunion behaviors between baby and mother

• when the mother leaves the room, they are distressed. When the mother returns, the baby wants to be close to the parent and is soothed.

  • Shows us that Parent is responsive and available

  • Is a predictor of positive social outcomes and higher cognitive functioning

• the baby is not extremely distressed when mother leaves, when mother returns they ignore the mother or turn away and don't return to prior level of play

  • Tells us that parent is unavailable and rejecting

• the baby is distressed when mother leaves, when mother returns they reject the mother's comfort and are angry at mother, does not return play immediately

• Tell us that parent is inconsistent, unreliable and sometimes intrusive

baby is distressed when mother leaves, but shows avoidant, mistimes, incoherent and freezing behaviors when the mother returns

• Parent is the source of security and also a source of fear, typically associated with parental trauma

disorganized attachment

a consistent pattern of inhibited, emotionally withdrawn behavior toward adult caregivers, manifested by bother of the following: the child rarely or minimally seeks comfort when distressed and the child rarely or minimally responds to comfort when distressed

• There is also minimal social and emotional responsiveess to others

• Limited positive affect

• Episodes of unexplained irritability, sadness, or fearfulness that are evident even during nonthreatening situations and environments

• The child must have experienced a pattern of extreme insufficient care

  • Social neglect/deprivation

  • Repeated changes of primary caregiver (ie foster care)

  • Rearing in unusual settings that severely limit opportunities to form selective attachments (ie raised in an orphanage/institution that has low child-to-caregiver ratios)

• a pattern of behaviors in which a child actively approaches and interacts with unfamiliar adults and exhibits at least two of the following:

  • reduced or absent reticence in approaching and interacting with unfamiliar adults, overly familiar verbal or physical behavior (that is not consistent with age/cultural boundaries), diminished or absent checking back with adult caregiver after venturing away, even in unfamiliar settings, or willingness to go off with an unfamiliar adult with minimal or no hesitation

  • The child similarly to reactive attachment, they must have experienced a pattern of extreme insufficient care

the child's long-term health and development after adoption

found that children adopted after spending 8 months in an orphanage had more insecure attachments and indiscriminate friendly behavior (even after a successful adoption) compared to children who spend 4 months, or were adopted but not in an international orphanage

found that if adoption occurs before or close to the sensitive period of attachment, the risk for enduring difficulties decreased

• The parent is interacting normal with the baby and then asked to stop interacting and is "flat"

• First the baby starts to demand attention and eventually goes into distress (for ONLY 2 MINUTES)

baby geese would attach to the first moving object they see after hatching

Harry Harlow studies baby monkeys, and found that monkeys separated from their mother preferred a "comforting" cloth mother over a wire mother that provided food

derives from the word "uterus"; was used to describe acute emotional and physical symptoms caused my psychological pathology

interested in what neurological damage caused from somatic symptoms. Found that under hypnosis, these symptoms disappeared; called this the "Great Nuerosis"

began to study hysteria in search of its underlying cause through analyzing his patients; be began to notice that the almost universal experience of childhood sexual trauma. Wrote a book that he found that the most common cause of hysteria was premature sexual experiences; because of this most people detested this

after WW1 men who had been exposed to the horrors of trench warfare displayed symptoms of "nervous breakdowns". Shell Shock victims experienced extreme emotional and physical distress; though shell shock was recognized as a real entity by some, it was not classified as a diagnosis

Vietnam War

women's liberation

war veterans and rape

exposure to actual or threatened death, serious injury or sexual violence in one (or more) of the following ways: directly experiencing the traumatic event, witnessing the event in person, learning that the traumatic event occurred to a close family member or friend that was violent and unexpected, experiencing repeated or extreme exposure to aversive details of the traumatic events (eg first responders, police officers)

• Intrusion symptoms

  • Recurrent, involuntary, and intrusive distressing memories of the traumatic events

  • Reckless or self-destructive behavior

  • Hypervigilence

  • Exaggerated startle response

  • Problems with concentration

  • Sleep disturbance

duration of the disturbance is more than one month

the disturbance causes clinically distress or impairment in social, occupational or other important areas of functioning

the disturbance is not attributable to the physiological effects of a substance or another medical condition

criteria A and under 30 days

• Marked distress that is out of proportion to the severity or intensity of the stressor, taking into account the external context and cultural factors that might influence symptom severity and presentation

• The symptoms do not represent normal bereavement

involves Alterations in regulation in affect and impulses, Alterations in attention or consciousness and Alterations in self-perception

• • Trauma exposure

    • Disorganized or agitated behavior may be an expression of intense fear, helplessness or horror

  • Re-experiencing

    • In young children, repetitive play may occur in which themes of aspects of trauma are expressed (intrusive thoughts)

    • In children, there may be frightening dreams without recognizable content (dreams)

    • In young children, trauma-specific reenactments may occur (flashbacks)

a dynamic equillibrium, or middle resting point that all organisms thrive to be at during all points

consists of the amygdala and hippocampus, thalamus, etc

• Controls our fight, flight, freeze response

• Regulates our emotional responses to stimuli

• Controls our stress response

• evaluates emotional stimuli and influences emotional memory and determines the emotional meaning of events

• forms memory and the retrieval of memory

  • Can help us in our stress response

amygdala, hippocampus

dictates the response to the stressor or emotion

neurotransmiiter system and neuroendocrine system

• Sympathetic nervous system is activated and controls the adrenal glands

  • When stress is triggered, adrenaline (epinephrine) and norepinephrine are released

• controls the HPA axis that is triggered during stress responses

  • HPA has the secretion of cortisol which prepares the body for fight/flight response

acute and chronic

behavioral flight-flight response which serves to respond to immediate danger

• promotes long-term adaptation and recovery to stress

  • Chronic traumatic stress causes an excess of cortisol to change brain structure, lead to less of some neurons, and growth of other types of neurons

bad

• A normal response to threat is necessary for survival and can heighten our awareness and performance

• There are positive types of stress

• Genetic background

• Early life traumatic experiences/early life experiences

  • If it happens 3 and under, this has more long-lasting consequences due to brain development

• Amount of chronic stress and subsequent changes in the brain function and structure

  • Can change brain size, PFC and emotional cortex, neural networks, etc that change stress response

• Temperament

contain the biological stress response at the time of the trauma, resulting in a cascade of alterations that lead to intrusive recollections of the event, avoidance of the reminders of the event and symptoms of hyperarousal

DNA methylation and histone acetylation

silencing (Turns Off the gene)

generally promotes gene expression

environment

Studied Rhesus monkeys and the affects of environment on the alleles of the Serotinin Transporter Gene (related to depression).

- Found that those monkeys reared by their mother’s all metabolized serotonin well regardless of allele type

– Those monkeys reared by peers who had l/l allele had no change in metabolism of serotonin

– Those reared by peers and had s/l allele had poor metabolism of serotonin and were at high risk for development of depression and anxiety

There are two types of genes: dandelions and orchids. “Dandelion” genes can thrive under any conditions, while “orchid” genes can only flourish under enriched and ideal environments, making them much more suceptible and vulnerable. However, in these ideal environments orchids are able to flourish more and become “society’s most creative, successful, and happy people”

Found that the short allele of the MAOA (monoamine oxidase) gene increased the chance of the development of antisocial behavior in human adults abused as children

In another study on depression, found that the risk for depression with risk allele increased if the person had a trauma.
