Epidemiology
National prevalence rates of various disabilities 400,000 with Spinal Cord Injuries 500,000 with Cerebral Palsy 2.3 million with Epilepsy 3.0 million with Stroke-related Disabilities 4.0 million with Alzheimer’s Disease 5.3 million with Traumatic Brain Injury 5.4 million with persistent Mental Illness 7.2 million with Mental Retardation
In the United States, at least 1 million sustain a TBI each year Incidence
Causes of TBI
Who is at Highest Risk for TBI? Males 1.5 times as likely as females to sustain a TBI Two age groups most at risk are 0-4 year olds and 15-19 year olds, and The elderly, frequently from falls African Americans have the highest death rate from TBI

The Executive Functions Inhibition Shift Regulation Initiation Working memory Planning / organizing Self-monitoring
The Executive Functions Bridging the now with the past Bridging the now with the future
School and Vocational Outcomes Problems initiating and completing work. Slowed work pace. Increased impulsivity. Trouble navigating physical surroundings. Decreased productivity.
School and Vocational Outcomes Confusion and increased stress. Resistance to change. Trouble with generalization of new learning. Distractible. May resent special assistance.
Social-Behavioral Outcomes Loss of friends and social circles. Decreased affective regulation. Increased impulsivity. Increased agitation.
Social-Behavioral Outcomes Poor perspective taking. Comparison to preinjury level of functioning. Poor understanding of TBI and recovery. Premature return to school/work. Unrealistic predictions.
Emotional Dependent behaviors / amotivation Irritability / emotional lability / anger Depression Disinhibition Denial/lack of insight At risk for substance abuse
Who Gets Better? Predictors of Positive Outcome x
Preinjury Predictors of Positive Outcome History of good academic achievement Good social relationships No history of learning, attention, or behavioral difficulties No history of substance abuse No significant family problems
Preinjury Predictors of Positive Outcome Strong-willed and determined Under 21 years of age No previous neurological history (e.g., a prior TBI) Good self regulation skills
Preinjury Predictors of Positive Outcome No criminal history Good relationships with family members Warm and supportive family No psychopathology
Behavioral Predictors of Positive Outcome Motivated and persistent Optimistic Has the capacity to recognize errors and self-correct Aware of behavioral deficits Ambulatory
Behavioral Predictors of Positive Outcome Relatively independent with activities of daily living Initiates tasks with no/minimal assistance Preserved perspective-taking capacity Relatively preserved neurocognitive abilities
Environmental Predictors of Positive Outcome Individual treatment plans Continuity and coordination of treatment throughout the recovery process Structure, consistency, and repetition in daily activities Good , stable resources (e.g., financial, family, friends, community, etc.)
Environmental Predictors of Positive Outcome Presence of “key” person in the family Family involved in the treatment plan Family realistic about individual’s status Presence of “key” person on team
Neurological Predictors of Positive Outcome Coma < 6 hours PTA < 24 hours GCS > 7 Normal EEG and MRI Normal intracranial pressure Normal ventricle size No intracranial hematoma
Indices of Severity of TBI Intracranial Pressure Retrograde Amnesia Anterograde Amnesia/Post-traumatic Amnesia Duration of Loss of Consciousness (LOC) Glasgow Coma Scale score Rancho Los Amigos Scale (1 to 10)
Indices of Severity of TBI
Mild injury 0-30 minute loss of consciousness Moderate injury 3 minutes to 24 hours LOC Severe injury > 24 hours LOC
Identification of tbi
Identification of TBI Obtain the medical records if possible Interview family/friends for collaboration Arrange for a neuropsychological evaluation Refer to a neurologist or psychiatrist for medication and behavioral consultation Consider referral to a brain injury rehabilitation program
Inquiry Regarding TBI Any history of concussion or head injury? Ever been knocked out? Note: this question may lead to discussion of Alcohol abuse Domestic violence Postconcussive symptoms? Return to work/school?
When did you wake up from the head injury? Do you remember being transported to the hospital? Do you remember being in the trauma unit? Being transferred to the rehab unit? PTA : period of time after the CHI for which the patient has no memory “Getting at” PTA in the clinical interview

Goals of Neuropsychological Assessment Determine spared versus impaired abilities. Understanding impact of injury and/or a neurodevelopmental problem (e.g., LD). Assist in localization of function and dysfunction.
Goals of Neuropsychological Assessment Assist in determining whether to remediate or to compensate. Generate suggestions for remediation and compensation. Suggestions for monitoring and tracking of progress in school setting.
When to Consider a Referral to Neuropsychology Documented brain injury/insult Suspected brain injury or insult Neurodevelopmental disorder Unusual psychological profile Positive neurological findings Severe behavior problems Treatment needs
The “Good-Fit” Personal Organizer for the Client with Executive Dysfunction 2 pages per day 7 am to 9 pm Contains a master to-do list With the client at all times Use for work and home Have only one system
Use of the personal organizer or PDA Move it from your head to your calendar Break long term goals into action items The organizer is your budget – how you “spend” your time Use your organizer for every part of your life
Use of the personal organizer or PDA Use your organizer for every part of your life Your to-do list should contain things you have to do, but also things you want to do, or to be, or to have. You make appointments with your doctor or insurance agent, because they’re important. You can make appointments with yourself as well. “Hi Cindy, this is David…..” (win friends and influence people with your amazing phone log)
Psychotherapy with the brain-injured client Mild TBI interventions Severe TBI interventions
Psychotherapeutic Interventions Individual Therapy Permitting appropriate expression of emotional reaction to TBI and loss Patient education Social skills training Family/spouse involvement Impact of memory problems and decreased insight
Psychotherapeutic Interventions Individual Therapy Critical for the therapist to be TBI-savvy Consider the environment in which the person functions “ Lieben und arbeiten ”
Psychotherapy with the brain-injured client Develop routines Energy conservation
Psychotherapy with the brain-injured client Values and motivators
Psychotherapy with the brain-injured client Self-esteem
Self - esteem
Activity Scheduling
Psychotherapy with the brain-injured client Substance abuse and dependence
Psychotherapeutic Interventions Group Therapy Modeling Problem solving Peer feedback Social skills practice
Behavioral Therapies Very few people with TBI have fully lost the ability to learn new behaviors Structure , consistency, and repetition Role of cognition in self regulation External feedback
This requires a measurable and precise definition of the target behavior Always get specific examples Cross check across settings “Pick your battles”? Inquire about the antecedents and consequences Behavioral Strategies: Defining the Problem
Behavioral Strategies: Identifying the Function Everybody’s doing the best he/she can Every behavior serves a function Every behavior problem is either A skills deficit, or A contingency problrm
Behavioral Strategies: Identifying Resources Personal resources: Memory? Flexibility? Persistence? Motivation? Social / family / peer resources Organizational resources
Behavioral Strategies: Guidelines Skills Safety Least restrictive Managing the antecedent: Set me up for success!
Examples of Behavioral Strategies Antecedents Does not understand Does not begin task Unable to do task Is not motivated Interventions Provide clear, concrete instructions; notes Give prompts; reinforce initiative Simplify task; provide skill-based training Increase interest or relevance; reward for task completion
Examples of Behavioral Strategies Consequences Avoids failure by not complying Gets out of work Receives attention for not doing task Gets to assert independence/control Interventions Alternate difficulty tasks with easy ones Premack principle Time out or ignoring; reinforce for attention Offer choices when appropriate
Behavior Management Strategies: X
Behavior Management Strategies: Agitation and Irritability
Behavior Management Strategies: Agitation and Irritability Redirection Offer an alternative activity Relaxation strategies Recognize antecedent conditions Speak calmly Use key familiar phrases
Behavior Management Strategies: Apathy
Behavior Management Strategies: Apathy Give choices between doing one thing or another; not between doing and not doing Activity scheduling, in advance
Behavior Management Strategies: Denial/Lack of Insight
Behavior Management Strategies: Denial/Lack of Insight Have ongoing discussions of “ strengths and needs ” Create discrepancy This may be the most difficult problem to address
Behavior Management Strategies: Impulsivity/Disinhibition Structured and organized daily routine Rewarding/praising impulse control and inquiring “how exactly did you do that?” “Talking stick”
Behavior Management Strategies: Depression/Withdrawal Help students identify preserved abilities and strengths - rather than focusing on their deficits Keep TBI survivor involved in the present rather than dwelling on the past Use active listening techniques, but focus on positive feelings

Family Issues and Needs Family stress related to severity of TBI The family’s resilience may be key to a brain injured child’s successful rehabilitation Divorce rates range from 15% to 54%
Sources of Family Stress Uncertainty about recovery Cognitive and personality changes Financial strain Transitions to “new” settings Lack of respite care
Family Definition of the Event
Family Issues and Needs Family’s adaptation may take years Any change may trigger emotional response Watch for signs of grieving
Return to School Accommodations and Modifications IDEA and Section 504
IDEA Definition of TBI: An acquired injury to the brain caused by an external physical force resulting in functional disability or psychosocial impairment that adversely affects a child’s educational performance.
School Re-Entry Issues Educational consultation should begin before return to school Continuity of care between school and rehabilitation services Prepare for multiple transitions Re-entry should include interdisciplinary support
Percentage Referred for Services
Basic Criteria for School Re-Entry Attends to a task for 10 to 15 minutes Adjust for age Can tolerate 20 to 30 minutes of classroom stimulation Can function adequately in a group of 2 or more students Engages in meaningful communication Follows simple directions accurately Gives some evidence of learning potential
School Re-Entry Procedures Assess needs Adaptive domain Cognitive domain Communication domain Sensorimotor domain Social-emotional-behavioral domain Transportation needs Family needs
School Re-Entry Procedures Identify the best setting for intervention Outpatient counseling? Home-based family interventions? School-based SLP / OT? Buddy system at school? In-service for school staff? Modified school day? In-school breaks? “Study halls” with resource teacher? Pre-vocational training? Regular re-evaluation for change over time
Developing IEP Goals Focus on 2 or 3 priority issues Identify metacognitive & organizational strategies Write measurable goals that incorporate the strategies Include specific information about how the strategy should be taught and implemented across settings Write short-term goals that are truly short-term
TBI Impact at School Problems initiating and completing work. Slowed work pace. Increased impulsivity. Topographical disorientation Distractible Difficulty generalizing new learning
Classroom Management Two key factors : Structure Motivation Explicitly teach rules & expectations Establish prompts or cues, such as gestures and reminder cards
Classroom Management Can students answer the following questions: What do I have to do? How much do I have to do? When am I finished? What do I do next ?
Classroom Management Use repetition & feedback Avoid multi-step instructions Supplement verbal instructions with nonverbal / modeling Provide additional time for information processing Assist with organization of materials and schedule
Classroom Management To be motivating, a task must be interesting Intersperse difficult or novel tasks with easy or previously learned ones Distinguish cognitive factors from other issues (impact of headache, or depression)
Specific Classroom Strategies: Attentional Processes Reward on-task behavior ; Use novel, unusual, relevant or stimulating activities Redirect Remove unneccessary distractors Explore a variety of cueing systems Verbal cues Physical prompts Gestural cues
Specific Classroom Strategies: Attentional Processes Reduce the number of individual tasks on a printed page Reduce the amount of copying from the board Provide a ruler or EZ-Reader to focus visual attention Avoid asking a student to multi-task Chunking / Pomodoro
Specific Classroom Strategies: Memory and Learning Enhance the saliency of material Regularly summarize information as it is being taught Dry-erase board Use overlapping techniques, such as repetition and rehearsal
Specific Classroom Strategies: Memory and Learning Couple new information with previously learned information Identify in advance the key information to be learned Make use of over-learning
Specific Classroom Strategies: Language Limit length and complexity of communication Do not use figurative speech Recognize the student may not understand humor or sarcasm
Specific Classroom Strategies: Language Reminders to start, end, or repair a conversation Use question prompts to help the student share more information, especially in groups Allow for slowed information processing
Specific Classroom Strategies: Language Speak slowly Reduce background noise
Specific Classroom Strategies: Visual Processing Provide longer viewing times or repeat viewings when using visual instructional materials Facilitate a systematic approach to reading and math by covering parts of the page Provide support for orientation to building and grounds Limit visual distractions (web page, handouts, text, desk)
Specific Classroom Strategies: Executive Functions Problem Solving Processes Develop a problem-solving guide to help student through the stages of problem solving Identifying the problem Acquire relevant information Generate several possible solutions List pros and cons for each solution Identify best solution Create a plan of action Evaluate the effectiveness of the plan Encourage generalization
Specific Classroom Strategies: Executive Functions Raise questions about alternatives and consequences Provide ongoing, non-judgmental feedback Provide part of a sequence and have the student finish it Frequent cues re: main topic vs. supporting ideas
Specific Classroom Strategies: Executive Functions Note impact of fatigue on cognition Note impact of some medications Consider reduced workload Consider note-taker “How exactly did you do that?”
In women reporting to ERs for injuries associated with DV: 30% of battered women reported a loss of consciousness at least once . 67% reported residual problems that were potentially head-injury related. (Corrigan 2003)
Domestic Violence… Greater than 90% of all injuries secondary to domestic violence occur to the head, neck or face region. (Monahan & O’Leary 1999)
Special cases Shaken baby syndrome
American Academy of Pediatrics-Committee on Child Abuse and Neglect Pediatrics 2001 “ … 95% of serious intercranial injuries and 64% of all head injuries in infants younger than 1 year were attributable to child abuse ” Pediatrics, 2001
Shaken Baby Syndrome
Shaken Baby Syndrome Rotational, acceleration, deceleration forces There may or may not be impact trauma Brain rotates inside the skull Bridging veins in the brain may be stretched or torn Subdural hematoma may develop
Shaken Baby Syndrome Kirschner & Wilson’s “dirty dozen” 1. Child fell from a low height 2. Child fell and struck head on floor or furniture, or hard object fell on child 3. Child unexpectedly found dead (age and/or circumstances not appropriate for SIDS) 4. Child choked while eating and was therefore shaken or struck on back
Shaken Baby Syndrome Kirschner & Wilson’s “dirty dozen” 5. Child suddenly turned blue or stopped breathing, and was then shaken 6.Sudden seizure activity 7. Aggressive or inexperienced resuscitation 8. Alleged traumatic event one day or more before death
Shaken Baby Syndrome Kirschner & Wilson’s “dirty dozen” 9. Caretaker tripped or slipped while carrying child 10. Injury inflicted by sibling 11. Child left in dangerous situation (e.g. bathtub) for just a few moments 12. Child fell down stairs
Combat Trauma TBI as “signature wound” of Iraqi conflict USA Today 9/07
Combat Trauma Iraq characterized by different kind of weaponry: explosive munitions. 15% of soldiers returning from Iraq may have sustained at least mild TBI ( Hoge et al 2008) 36% may have been exposed to blasts ( Maguen et al 2012)
Combat Trauma Comorbid PTSD Headache Sensory impairment Alcohol use
Special cases Alcohol abuse/ dependenc y
Alcohol Abuse May increase morbidity of MVA-related TBI (Cunningham et al 2002) Although low amounts may be protective Chronic alcohol abuse associated with falls, assaults, multiple head injuries Overlay of alcohol-related impairment
Special cases Mild TBI
TBI Severity: Mild TBI (mTBI) Concussion signs and symptoms include ANY changes in behavior such as: Cognitive impairments Physical symptoms (e.g., headaches, blurry vision, diplopia , dizziness) Emotional symptoms (e.g., irritability, volatility) Sleep difficulties Not “feeling like themselves.”
TBI Severity: Mild TBI (mTBI) Persistent symptoms following the concussion is often referred to as Post-Concussive Syndrome . Cumulative effect
Psychotherapy with the persistent post-concussive client Perfectionistic tendencies Somatic focus Poignancy Secondary gain “old me / new me” Check to see whether you are working at cross-purposes
