Behaviors in Early RecoveryDisorientationParanoid IdeationDepressionHypomaniaConfabulation
10/21/2004 Brookhaven Hospital 11
Behaviors in Early Recovery RestlessnessAgitationCombativenessEmotional LabilityConfusionHallucinations
10/21/2004 Brookhaven Hospital 12
In the early phase of TBI recovery, some behaviors can resemble a psychiatric illness.
10/21/2004 Brookhaven Hospital 13
Biological Aspects of Injury Further Psychological Problems
Seizure disorder may include irritability and behavior dyscontrolCognitive problems, especially memory, affect, emotional responseDenial of deficits may affect capacity to receive helpPreviously effective medications may not work or may exacerbate injury-related problemsDepression may prevent participation
10/21/2004 Brookhaven Hospital 14
The Basic Person Doesn’t ChangeThe injury alters specific aspects of the person’s psychological, cognitive and emotional functionSpecific personality traits or style remain
10/21/2004 Brookhaven Hospital 15
TBI Affects All Aspects of LifePreviously competent individuals may show symptoms of psychiatric diseaseCoping skills are stressedBehavioral controls are lost
10/21/2004 Brookhaven Hospital 16
TBI Affects All Aspects of LifeSocial skills and roles are affectedInsight into TBI-related changes may be limitedPreviously self-managed symptoms may become out of controlRelationships/support systems are stressed
10/21/2004 Brookhaven Hospital 17
Positive Predictors of Recovery Outcome
Focal vs. Globalized injuryAggressive early intervention and trauma careWork history
10/21/2004 Brookhaven Hospital 18
Positive Pre-Injury Predictors
Medical/behavioral complicationsPre-injury achievement levelLearning, school and work historyExtroverted personalityPositive social history
Level of severity, coma durationNatural recovery and return of functions
10/21/2004 Brookhaven Hospital 19
Positive Pre-Injury Predictors
“Good character” and self controlStrong-willed, determined personality
Perseverance and motivationStrong social and family network and supportAbsence of pre-injury psychiatric symptomsAbsence of substance abuse
10/21/2004 Brookhaven Hospital 20
Negative PredictorsPoor response to psychiatric medicationsPoor response to “talking” therapiesFailure in behavioral programs requiring memory and problem-solvingSocial network failure: divorce, separation
10/21/2004 Brookhaven Hospital 21
Negative PredictorsFailure at workInvolvement in the criminal justice systemPersistence of chronic pain and headache symptomsLack of support system
10/21/2004 Brookhaven Hospital 22
Lateralization Issues of Behavior Deficits
Left Hemisphere: depression, agitation, anxietyDiffuse: attention, concentration, arousal, response
Right Hemisphere: unable to respond, flat affect
10/21/2004 Brookhaven Hospital 23
TBI and Psychiatric DiseaseTraumatic Brain Injury can mimic
psychiatric symptoms Examples: memory problems, behavioral
and emotional control problems, mood disorders
10/21/2004 Brookhaven Hospital 24
Biological Brain Changes can Mimic Psychiatric Disease
Biological changes can exacerbate a pre-existing psychiatric diseaseExecutive Syndrome can resemble a thought disorderBehavioral features can resemble other conditions
10/21/2004 Brookhaven Hospital 25
TBI and Psychiatric DiseaseTBI can mask psychiatric
symptomsExample: Frontal system
damage can produce expressive aposody/blunting, which may reduce the person’s ability to express sadness
10/21/2004 Brookhaven Hospital 26
Risk Factors Associated with Psychiatric Diagnosis (Lishman, 1988)
Organic factors Psychosocial factors (socio-economics, pre-morbid personality)Past history of psychiatric illnessFamily history of psychiatric illnessMaleEmergence of problems one year post-injury
10/21/2004 Brookhaven Hospital 27
Research HighlightsLocalization of injury (Fann, 1995)Noradrenergic and serotonergic projections are sites of contusion (Rosenthal, 1998)Individuals with depression and anxiety perceive themselves as more ill (Fann, 1995)
10/21/2004 Brookhaven Hospital 28
Research HighlightsReaction to failure (Alexander, 1975, 1992)Right hemisphere damage (Silver, 1992)Pre-morbid factors and social adjustment (Robinson & Jorge, 1993)Biochemical response (Robinson & Jorge, 1993)
10/21/2004 Brookhaven Hospital 29
Brain Injured Patients with Psychiatric Disorders (Van Reekum, 2003)
The level of severity of the person’s brain injury relates to the potential for the emergence of psychiatric disorders in the first 24 months post-injury
10/21/2004 Brookhaven Hospital 30
Personality Disturbances After Brain Injury
Anxiety or “catastrophic reaction”Emotional lability/disinhibitionParanoia and psychomotor agitationDenialDepressionSocial withdrawalAmotivation/abulia
10/21/2004 Brookhaven Hospital 31
Distinguishing Brain Injury from Psychiatric Problems
Physical injury to the brainCognitive and behavioral deficitsEmotional and personality changeAttention, concentration, arousal, filteringMemory problemsSeizure problemsSelf regulation
10/21/2004 Brookhaven Hospital 32
Psychological Syndromes can Co-occur or Predate Injury
When did the symptoms emerge, before or after the TBI?What were persons like before injury?What were their coping styles?How have they adjusted to disability?What new symptoms/behaviors have developed?
10/21/2004 Brookhaven Hospital 33
Problems in Diagnosing Psychiatric Illness in TBI
Timing between injury and emergence of symptomsIn mild cases lack of documentation of extent/severity of injuryPre-morbid personality traitsPre-injury issues
10/21/2004 Brookhaven Hospital 34
Rate of Psychiatric Illness One Year Post Brain Injury
Past studies focused on individuals with TBI who were seen in psychiatric hospitals
21.7% of individuals with TBI had ICD-9 diagnosis vs 16.4% of general population (1998)
10/21/2004 Brookhaven Hospital 35
Psychiatric Diagnosis Distribution Following TBI
Male - 21.6%Female – 11.3%Mild brain injury –17.2%Moderate and severe brain injury – 23.3%
10/21/2004 Brookhaven Hospital 36
Psychiatric Diagnosis FeaturesRelationship of psychiatric diagnosis to:
Younger ageGlasgow outcome scale scoreHistory of pre-injury ETOH use/abuseHistory of psychiatric illnessLower Mini Mental State scoreFewer years of education (Deb, 1999)Not working before injury (Bowen, 1998)
10/21/2004 Brookhaven Hospital 37
Psychiatric Issues in TBI CasesMale/female 70%/30% more likely to develop psychiatric symptomsElevated risk for bi-polar affective disorderSeizures noted in 50% of cases with mania (Shukla, 1987)Limbic system lesions in 75% of manic cases (Starkstein, 1987)Family history of mood disorders
10/21/2004 Brookhaven Hospital 38
Diagnostic Issues in BI GroupDepressive episode 13.9% vs. 2.1%Panic Disorder 9.0% vs. 0.8%Generalized anxiety 2.5% vs. 3.1% Phobic disorder 0.8% vs. 1.1%Obsessive compulsive 1.6% vs. 1.2%Schizophrenia 0.8% vs. 0.4%ETOH dependence 4.9% vs. 4.7%
10/21/2004 Brookhaven Hospital 39
Brain Injury and DepressionDepression following brain injury occurs at a rate of 44.3% vs. 5.9% in non-brain injured population
10/21/2004 Brookhaven Hospital 40
Differential Diagnosis IssuesHow can the clinician determine the role of injury and pre/post injury psychiatric factors that contribute to behavioral dysfunction?
10/21/2004 Brookhaven Hospital 41
Pre-existing Psychiatric Disorders Related to TBI
Dementia due to head injuryCognitive disorderBipolar disorder (manic or depressive typesMood disorders (depression, mania)Sleep disorderAnxiety disordersIntermittent explosive disorder
10/21/2004 Brookhaven Hospital 42
Pre-existing Conditions can Affect Recovery from TBI
Limited coping skillsImpaired ability to manage symptomsCognitive problems limit capacity to manage disability and pre-existing conditionAdvent of new behaviorsPrior medications may increase cognitive problems
10/21/2004 Brookhaven Hospital 43
Effect of TBI on Underlying Psychiatric Disease
Reduced capacity to self-manage symptomsDiminished impulse control leads to enhanced interpersonal problemsPsychological defenses and coping skills fail to functionDenial of deficits prevents person from responding to injury-related deficits
10/21/2004 Brookhaven Hospital 44
Effect of TBI on Underlying Psychiatric Disease
Interpersonal relationships changeSocial role is alteredSeizures and dyscontrol event are misinterpretedEnhanced dependent needs affect psychological status
10/21/2004 Brookhaven Hospital 45
Adjustment Difficulty due to Emotional & Behavioral Issues
Emotional changeImpaired perception of social interactionImpaired self controlIncrease dependencyBehavioral rigidity
10/21/2004 Brookhaven Hospital 46
Most Frequent Problems Cited by Family Members
SlownessIrritabilityImpatienceDepressionMemory
10/21/2004 Brookhaven Hospital 47
Co-Morbidity: PTSD & TBI (Arnon, 1998)
32% of motor vehicle accident victims meet diagnostic criteria for PTSD one year post-injuryThose with PTSD have higher rates of pre-morbid/co-morbid psychopathology (anxiety and affective disorders)Immediacy of PTSD symptoms is a better predictor of later PTSD than injury severity
10/21/2004 Brookhaven Hospital 48
Role of Prior Learning or Attentional Problems in Occurrence of Psychiatric Diagnosis
Prior learning and attentionalproblems are enhanced Diminished filtering and stimuli selectionAltered coping skills produce dysfunctional responses
10/21/2004 Brookhaven Hospital 49
Psychiatric Issue or Brain Injury?
Mania vs. Arousal problems AnxietyDenial ConfusionDepressionCognitive problemsPersonality changesIntellectual changesThought disorder vs. Thinking problem
10/21/2004 Brookhaven Hospital 50
Psychiatric Features of TBI Mania - AgitationAnxiety - Catastrophic Reaction(Goldstein)Denial - Inability to accept deficitsConfusion - Disorientation and memory problemsDepression – Withdrawal, abulia
10/21/2004 Brookhaven Hospital 51
Neurologic and Neuropsychiatric Features
Atypical seizure disordersIntermittent explosive disorder (Yudofsky)Neurologic rage or limbic-psychotic aggressive syndrome (Dorothy Lewis)
10/21/2004 Brookhaven Hospital 52
Neurologic Rage IdentifiersSudden loss of behavioral control, “out of the blue”Inability to stop the behaviorSeizure-like quality, unawareness of the individual to the eventDeficient memory of the event (Dorothy Lewis)
10/21/2004 Brookhaven Hospital 53

Implications for Rehabilitation:
Why Patients “Fail”
10/21/2004 Brookhaven Hospital 69
Persistent Problems of Recovery and Rehabilitation
HypersexualityHyposexualityDependencySilliness/EuphoriaAggressivityApathyChildishnessDisinhibition
10/21/2004 Brookhaven Hospital 70
Why Patients “Fail”
Strategy:Individual and Group Psychotherapy
Why?Can’t identify problems as shared by othersDifficulty maintaining behavioral alternatives
10/21/2004 Brookhaven Hospital 71
Why Patients “Fail”Strategy:
Insight-Oriented Approaches
Why?Can’t identify problem with selfProblems with generalization
10/21/2004 Brookhaven Hospital 72
Why Patients “Fail”Strategy:
Didactic Approaches
Why?Memory problems prevent use of previous learning
10/21/2004 Brookhaven Hospital 73
Why Patients “Fail”Strategy:
Milieu Treatment
Why?Social deficits inhibit positive peer group membership
10/21/2004 Brookhaven Hospital 74
Why Patients “Fail”Strategy:
Cognitive-Behavioral Therapy
Why?Memory problems and difficulty with generalizations
10/21/2004 Brookhaven Hospital 75
Why Patients “Fail”Strategy:
Behavior Modification
Why?Problems with impulse controlMemory problems prevent reinforcement strategy from being effective
10/21/2004 Brookhaven Hospital 76
Why Patients “Fail”Strategy:
Medication Management
Why?Some medications further cognitive problems or cause disinhibited behavior
10/21/2004 Brookhaven Hospital 77
Why Patients “Fail”Strategy:
Addictive Treatment/Self-Help Groups
Why?Cognitive problems prevent identification with the speaker/group processIndividual cannot apply information to self
10/21/2004 Brookhaven Hospital 78
Why Patients “Fail”Person cannot process “talking therapies”Limited insightNew behaviors (e.g. impulsivity) are related to the brain injuryIncreased dependenceUnable to relate to previously effective support groups (e.g. AA, NA)
10/21/2004 Brookhaven Hospital 79
Support System Stresses Increase Psychological Issues
High incidence of divorce or loss of primary relationship (50% in first two years post-injury)Adult children return to aging parents for physical assistanceLoss of friends and workHigh potential for substance use/abuseLoss of social role with family, friends and communityCultural factors influence recovery
10/21/2004 Brookhaven Hospital 80
Social Network Issues Complicate Rehabilitation
Social network failure seen 24-months post injury (Burke and Weslowski. 1989)Psychological effect of withdrawal or loss of supports
10/21/2004 Brookhaven Hospital 81
Social Network Issues Complicate Rehabilitation
Changing social role post-injury affects self-image and self-worthIndividual response to loss of functions and social changesRecidivism and emergence of psychiatric symptoms commonly seen 12-24 months post-injury
10/21/2004 Brookhaven Hospital 82
Increasing Success in Rehabilitation and
Treatment:
What Works!
10/21/2004 Brookhaven Hospital 83
What Works?Early identification of problemsHighly structured, social learning environmentRepetitive “teaching” of behavioral alternativesExternal controls managed by staff, gradually transferred to the individualNeurological approach to medication managementIntegrated rehab program, including psychiatric and substance abuse treatment
10/21/2004 Brookhaven Hospital 84
What Works?Emphasis on learning and relearning of social roleTeaching “scripts” for social interactionGuided/supported attendance at AA/NA/self-help groupsUse of “failures” within treatment to address denial and limited insight
10/21/2004 Brookhaven Hospital 85
What Works?Focus on social role re-entry and response of family, friends, co-workers, peers, and others to the personStaff understanding of TBI-related behavioral, cognitive, emotional and psychological issuesUnderstanding of adjustment to disabilityTeaching individual about consequences of TBIPromoting return to work, avocational and recreational activities
10/21/2004 Brookhaven Hospital 86
What Works?Consistent response from staff throughout the environment Use of behavioral analysis to understand brain/behavior issuesAvoidance of negative consequences for behavior problemsFocus on discharge engineering to assure that the individual moves to a supportive placement with the solid transfer of information and management techniques
