    Hsv 6350 Module I Part 1 Neurobiology Of Trauma Dr. Mark Sloane - Presentation Transcript

    1. The Impact of Child Trauma & Prenatal Alcohol Exposure on Neurobiological Development & Function Western Michigan University College of Health & Human Services HSV 6350-105 Special Topics Course: Child Trauma Module I , Part I Mark A. Sloane, DO Center for Behavioral Pediatrics WMU Children’s Trauma Assessment Center Kalamazoo, MI
    2. Western Michigan University
    3. Western Michigan University SW MI Children’s Trauma Assessment Center
    4. Module 2
      • Brief review of normal brain development
      • Review of “Brain-Behavior Connections” in FASD & child traumatic stress
      • Neurodevelopmental Function in FASD & child traumatic stress
      • Treatment overview in FASD & child traumatic stress
    5.  
    6. The Harsh Reality…
      • Research continually demonstrates the harmful effects of child traumatic stress & prenatal alcohol exposure
      • We have a reactive system rather than a proactive system
      • We minimize the impact to these children to protect ourselves from the overwhelming awareness of how damaging their experiences are
    7. Exploring the “Why” Behind Problematic Behavior
      • Requires a reframing of often long-standing paradigms re the etiology of “bad behavior”
      • Multiple factors: This is complex !!!
      • Requires a community-wide shift of thinking differently
      • The power of the trans-disciplinary mindset
    8. Paradigm Shift: Reframing Our Understanding of Behavior
      • “ Bad” behavior in children & adolescents is often about faulty & defective brain wiring
      • It is not disrespect because the child is “ BAD ”
      • Perceived “bad” children:
        • Do NOT have adequate skills of flexibility/adaptability…
        • Often have low frustration tolerance…
        • and also have significant difficulty applying these skills when they are most needed. (Greene, 2001)
    9.  
    10. Our typical response to “bad” behavior in children
      • These kids get all kinds of labels
        • Educational System (special education classifications)
        • Medical System (DSM-IV diagnostic categories)
        • Legal System (at-risk teen, juvenile delinquent)
      • They often get labels that imply they are BAD or NAUGHTY
      • ADHD, Oppositional Defiant Disorder (ODD), Conduct Disorder, Bipolar Disorder (& even PTSD) diagnoses do NOT capture the full extent of the neurodevelopmental & neurobehavioral impact for kids with problem behaviors
    11. These labels just don’t fit!!!
    12. The challenge of dealing with difficult children…
      • “It may be when we no longer know what to do…
      • we come to our real work …
      • And…when we no longer know which way to go…
      • we have begun our real journey .”
      • Wendell Berry
    13.  
    14. News Flash : We live in strange times!
      • Modern Western society has benefited (beyond the dreams of our ancestors) from many advances in:
        • Technology
        • Communications
        • Transportation
        • Social Justice
        • Economy
      … however….
    15. News Flash: We live in strange times!
      • Our society seems incapable of ensuring that our children grow up in environments that are:
        • Safe
        • Predictable
        • Rich in positive relationships
        • Humane
    16. News Flash: We live in strange times!
      • Hundreds of thousands of children are terrorized, abused, neglected, maltreated, exposed to alcohol/drugs each year
      • These kids are at great risk for emotional, behavioral, social, cognitive, and physical health problems
      • The overall costs are incalculable
      • How can we really measure the lost potential here?
    17. News Flash: We live in strange times!
      • How “advanced” is our society when…
        • We have to create vast expensive government agencies whose sole purpose is to protect children from their parents!
        • These very agencies (despite our best efforts) truly fail these unfortunate children by…
          • Recreating the chaos, fragmentation, trauma, and neglect these kids experienced in their biological homes
    18. A Step Closer… to understanding these kids
      • The Brain – Behavior Connection
    19. Normal Brain Development and Organization
    20. Brain Glossary
      • Neuron (nerve cell)
        • “Raw material” of the brain
        • 100 billion neurons at birth (most of what we will need throughout life)
      • Synapse
        • The connection between neurons
        • 1,000 trillion synapses by age 3
        • 500 trillion synapses by adolescence
          • Due to “pruning” (discarding)
    21. Brain Development / Learning
      • The process of creating, strengthening, & discarding synapses
      • Synapses organize the brain by forming neuronal pathways that connect the parts of the brain governing everything we do:
        • Breathing
        • Sleeping
        • Thinking
        • Feeling
    22. Neurobiology of Development
      • Nature PLUS nurture !!!
      • “ Hard-wired” genetic programs (blueprints) are continuously modified by the environment (from conception  death)
      • Brain “sculpts” itself in response to the environment AT THE SAME TIME it is developing (via genetic blueprints)
      • “ These interactions organize our brain’s development and thus shape the person we become” (Shore 1997)
    23. From simple to complex: Hierarchy of brain function Brain- stem Diencephalon Limbic Neocortex Abstract Thought Concrete Thought Affiliation w/ mate Attachment Sexual Behavior Emotional Reactivity Motor Regulation Arousal Appetite / Satiety Sleep BP / Heart Rate Respiratory Drive Body Temperature Perry 2006 All sensory input enters here
    24. Neural systems change in a use-dependent fashion during development
      • Healthy organization of all neural networks depends upon:
        • Pattern
        • Frequency
        • Timing
      • of key experiences during development
      • Example : Child must be exposed to language-rich environment to develop optimal language function
    25. Brain develops in sequential fashion: from simple to complex Brain- stem Diencephalon Limbic Neocortex Development begins here
    26. The brain develops most rapidly early in life
      • By age 4, the brain is 90% of adult size!
      • It is much easier to organize the brain in healthy ways in early childhood…
      • It is much more difficult to re-organize a poorly organized brain due to traumatic stress and / or FASD
    27. Neural systems can be changed… but some systems are easier to change Brain- stem Diencephalon Limbic Neocortex Complexity Plasticity & Ease of change
    28. The Brain-Behavior connection: three primary components
      • Genetics
        • What you inherit from both parents
      • Intrauterine environment
        • During pregnancy
      • Extrauterine environment
        • After pregnancy
    29. The Brain-Behavior Connection
      • Genetics
        • Neurodevelopmental strengths / weaknesses
        • Temperament / Personality
        • Family history of:
          • Attentional disorders
          • Learning disorders
          • Mood disorders
          • Neuropsychiatric disorders
    30. The Brain-Behavior Connection (cont.)
      • Intrauterine environment
        • Exposure to drugs (legal / illegal)
        • Exposure to alcohol
        • Maternal stress
        • Maternal nutrition
    31. The Brain-Behavior Connection (cont.)
      • Extrauterine environment
        • Parental attachment / nurturing
        • Parental style / psychopathology
        • Overall family climate
        • Influence of extended family system
        • Inadequate nutrition
        • Exposure to violence, natural disasters
        • Exposure to neglect

    36. Influence of Prenatal Alcohol Exposure
    37. Fetal Alcohol Syndrome
      • FAS is among the most common of the known causes of cognitive impairment
        • A major public health problem.
        • How common is it? (1-3/1000 live births in US?)
        • Regional variations
        • How does it affect the CNS?
        • What can we do about it?
        • Why don’t more professionals know about it?
    38. Fetal Alcohol Syndrome
      • “ Discovered” in 1968 & 1973
      • Specific pattern of facial features
      • Evidence of Central Nervous System (CNS) dysfunction / damage
      • Growth deficiency

    39. FAS: only the tip of the iceberg!
      • Fetal Alcohol Spectrum Disorders (FASD)
      • Fetal Alcohol Syndrome
      • Alcohol-related Neurodevelopmental Disorder (ARND) (“mild-moderate” FAS)
      • Prenatal Exposure to Alcohol (clinically suspected to have FAS but appear physically normal )

    54. Mechanisms of cellular damage by ethanol in FASD
      • Timing is everything!
      • Binge drinking vs chronic alcohol use
      • John Olney (Wash U. – St. L) mouse model:
        • GABA A & glutamate (NMDA) receptor dysfunction
        • Serotonin system dysfunction
        • Disrupted synaptogenesis (neurons making connections with other neurons)
        • Results in  programmed cellular suicide (apoptosis)
    55. Risk Factors for FASD: Why doesn’t every fetus exposed to alcohol look the same?
      • Dose of alcohol (mom’s blood alcohol level = fetal blood alcohol level)
      • Pattern of exposure : binge > chronic drinking
      • Developmental timing of alcohol exposure
      • Genetic variations
      • Synergistic reactions with other drugs
      • Interaction with nutritional variables
      • Socio-economic status
      • Possible neuroprotective factors
    56. Child Traumatic Stress & the Developing Brain
    57. Traumatic Stress & the Child’s Developing Brain
      • Research reveals a strong link between all types of child abuse and the subsequent development of psychiatric illness in adulthood
      • Until recently, many/most MH professionals felt that these psychiatric conditions developed via psychological means:
        • “software” problems amenable to reprogramming (talk therapy) or simply erasable (“Just get over it”)
    58. Traumatic Stress & the Child’s Developing Brain
      • Early childhood traumatic stress to the developing brain results in:
        • Physical (not always permanent) changes :
          • “ Hard-wired” neurological changes
          • Causes abnormal CNS organization / function
          • Profound implications re behavior / development / learning / cognition
          • Prevents realization of genetic potential
    59. What does traumatic stress change in the brain?
      • Attachment
      • Affect / Emotion Regulation
      • Information Processing

    63. Neurobiologic “Controversy”
      • Two prominent researchers in FASD (Ed Riley) & traumatic stress (Martin Teicher) recently met and were unable to differentiate their MRI research slides
      • New strategies greatly needed to research these two groups separately
      • Here is a brief look at some recent functional MRI research…
    64. Recent Neuroscience Research
      • New brain research has dramatically altered our thinking about traumatized / FASD children
      • New neuroimaging methods have driven this research:
        • Quantitative MRI (Magnetic Resonance Imaging)
        • Functional MRI
        • PET (Positron-Emitted Tomography)
        • SPECT (Single-Photon Emitted Computed Tomography)
        • MRS (Magnetic Resonance Spectroscopy)
        • DTI (Diffusion Tensor Imaging)
    65. Adult ADHD Neuroimaging Study
      • 8 Adults with ADHD
      • 8 Controls
      • George Bush, MD, PhD
      • Functional MRI
      • Performed Stroop test while in fMRI scanner
    66. Stroop Test

    68. OK…it’s time to make it real!
    69. What does all of this mean to health professional students?!
      • 5 CNS pathways to explosive / inflexible kids:
        • Executive Function Skills
        • Language-Processing Skills
        • Emotion regulation Skills
        • Cognitive Flexibility Skills
        • Social Skills
      Ross Greene, 2005
    70. Traumatic Stress / FASD and the Developing Brain: Executive Function: Making it real
      • Working Memory (“RAM” of the brain)
        • Allows efficient multi-tasking
      • Separation of affect
        • Regulating arousal to achieve goals (e.g. learning)
      • Organization & planning
        • Facilitates problem-solving
      • Shifting cognitive set
        • Allows child to smoothly transition from their own agenda to the supervising adult’s agenda
    71. Traumatic Stress / FASD and the Developing Brain: Language Processing: Making it real
      • Often unnoticed, often unassessed
      • Problems identifying internal emotions
      • Lack the capacity to “inform the world” that they are frustrated
      • Problems with conflict resolution
        • Teacher: “Use your words, young man!”
        • Student: “(expletives deleted)”
    72. Traumatic Stress / FASD and the Developing Brain: Emotional Control: Making it real
      • Impaired ability of the right brain to communicate w/ the left brain
        • Via Corpus Callosum (connects R with L)
        • Balance problems
        • Sensory processing problems
        • Anger / explosiveness (  self-calming)
        • Loss of logical left brain function (language / memory) when stressed
    73. Traumatic Stress / FASD and the Developing Brain: Emotional Control: Making it real
      • Traumatized / FASD kids often have significant difficulty regulating emotional experience :
        • Problems expressing emotions in a safe manner
        • Impaired modulation of emotional experience
    74. Traumatic Stress / FASD and the Developing Brain: Emotional Control: Making it real
      • “ Fight-Flight-Freeze” phenomenon is common & underappreciated
        • Hypersensitive / overactive F-F-F system often a daily battle for traumatized / FASD children
        • Fear / Anxiety  Anger connection
          • “Look in their eyes during a meltdown (if you dare) and you will often see fear” …MAS
        • Amygdala is the key player here
    75.  
    76.  
    77. Traumatic Stress / FASD and the Developing Brain: Cognitive Flexibility: Making it real
      • Concrete / literal thinkers
      • Rigid behavioral templates for specific situations
      • Rule-driven (to a fault)
      • Over-focus on details
      • Overlap with the autistic spectrum
    78. Traumatic Stress / FASD and the Developing Brain: Social Skills: Making it real
      • Impulse control problems
      • Pragmatic language impairment
      • Inaccurate interpretation of social information
      • Unable to predict social outcomes
