Incidence of TBI/mild TBIIncidence of TBI/mild TBI
CDC Statistics� 1.4 million incidence/5.3 million prevalence� 75% considered “mild”McKinlay et al. 2008� 1 in 5 children will sustain a brain injury before age 16 of which 90% are judged to be “mild”
U. S. Government� 50% of all war-related injuries – TBI� 23% of all returning soldiers� 80% “mild
Pashek, 2010
“Mild” Traumatic Brain Injury“Mild” Traumatic Brain Injury
� Life disruption is not necessarily proportional to the “mildness” of injury as judged by a medical evaluation
� Doesn’t mean effects will be less dire on pt or family
� Pt’s awareness of problem often creates greater frustration than in more severe TBI
� “I don’t look any different, but I know I’m different.” People don’t understand.”
� Percussion effects of multiple blasts on the brain

� Increased incidence of TBI and mTBI in the Iraq and Afghanistan wars relative to previous wars◦ 80% of all war-related injuries are blast-related
◦ 40-50% involve traumatic brain injury
◦ High order explosives
� Susceptibility of military roles
� Increase in survival - improved protective equipment (body armor, Kevlar helmet)

Civilian CasualtiesCivilian Casualties
� Civilians are at risk during war, both children and adults
� Terrorism is increasingly affecting civilians◦ 2000-2003 70 suicide bombing attacks – Israel (Weil et al., 2007),
◦ Oklahoma City – Murrah Building 1995◦ Madrid train bombings 2004◦ London bus bombings 2005
� Other accidents involving explosions (e.g., gas leaks, fireworks accidents, etc.)
� Children more likely to develop head injuries than adults or adolescents

� Direct Injuries – 4 levels defined◦ Primary (positive and negative blast wave)
◦ Secondary (projectiles hitting the body)
◦ Tertiary (the body as projectile)Quaternary (burns, crush injuries, injuries from toxic fumes)
� Indirect Injuries
Pashek, 2010
Primary Blast InjuryPrimary Blast Injury
� Primary Blast: Atmospheric over-pressure followed by under-pressure or vacuum; 1,000 mph◦ Skull displacement causing tension and pressure in the brain
◦ Contusions
◦ Diffuse Axonal Injury (DAI)

Primary Blast InjuryPrimary Blast Injury
Contusions Coup/Contrecoup
� Localized damage also
occurs when the brain bounces against the skull.
The brain stem, frontal
lobe, and temporal lobes are particularly
vulnerable to this because
of their location near bony protrusions inside the
skull.
Pashek, 2010
Primary Blast InjuryPrimary Blast Injury
Vulnerable Areas
◦ Diffuse axonal injury (DAI) –hippocampus, amygdala, brain stem)
◦ Transfer of kinetic energy from blast wave to brain, causes DAI
◦ Cernak et al. - blast injury effects on rats� swellings of neurons, glial reaction, and myelin debris in the hippocampus
� Performance deficits within 3h

Blast Injury Blast Injury -- PolytraumaPolytrauma
� High pressures lead to air-filled organ failure
� High frequency of vasospasms – early and late (Ling, Bandak, Armonda, Grant & Ecklund, 2009)
� Risk of pseudoaneurysm
�Multiple blasts - decreased threshold of internal organ injury (Yang et al. 1996)
Pashek, 2010
Blast Injury vs. Other TBI Blast Injury vs. Other TBI EtiologyEtiology
� Blast injury/sports injury – both have risk of repetitive injury◦ Sports – concern for Second Impact Syndrome◦ Military following of concussion guidelines? A complex issue
� Cognitive effects of multiple concussions –memory and attention (Moser, 2005; Guskiewicz, 2005 et al.)
� Yet, blast injury is more complex than sports concussion, given the over-pressure and under-pressure atmospheric dynamics and the quaternary collateral trauma.
Pashek, 2010
Many Issues Remain Re Military Many Issues Remain Re Military BlastBlast--related TBIsrelated TBIs
� Search continues for reliable biomarkers
� Present documentation is only self-report
� Criteria for removing soldiers from the field?
� Repetitive (percussive) injuries common
� There is little post-injury monitoring after a MTBI ◦ Limitations of self-report

Military BlastMilitary Blast--Related TBIRelated TBI
“If you're talking about white, or even gray matter damage, it's often accompanied by loss of cognitive insight. If we're releasing these soldiers to the field with instructions to report any changes in their mental state, it probably won't happen because the person who suffers a mild brain injury is the least able to observe it in themselves. If a platoon leader sees them as filling a necessary niche and they appear to be doing well, they are not going to encourage them to report symptoms, either.”
(Graf man, as Cited in Samson, 2007)

Complicating Factors in the Study and Complicating Factors in the Study and Treatment of Blast or Other mTBI Treatment of Blast or Other mTBI -- PCSPCS
Post-Concussive Syndrome
� Most individuals with mild TBI recover fairly well within 3-6 months post-injury
� 10-30% - chronic post-concussive symptoms.� Three categories of residual symptoms: ◦ Somatic (headache, tinnitus, sleep disorders etc.)◦ Cognitive(memory, attention and concentration difficulties
◦ Emotional/Behavioral(irritability, depression, anxiety, behavioral disorders) and at risk for other psychiatric disorders including:� Depression� Vulnerability to post-traumatic stress disorder (PTSD)

PTSD in TBI: ControversiesPTSD in TBI: Controversies
� It has been argued that PTSD cannot occur in amnestic patients, those with LOC or other severe BI symptoms (Mayou, Bryant, & Duthie)◦ Amnestic disturbance may not be complete, as described by King – “islands” of memory
� Levi et al. (1999) actually found higher rates of PTSD symptoms in children with severe TBI than in children with moderate TBI or orthopedic injuries
� Combat related PTSD can surface and remain many years post-trauma
� Autobiographical memory training may not be beneficial to individuals with PTSD
Pashek, 2010
CombatCombat--Related PTSDRelated PTSD
There is no “front” to the war as in previous conflicts
� Flashbacks
� Nightmares
� Hypervigilance
� Dissociation
� Persistence of symptoms for long periods of time

Traditional Neuroimaging Methods and Traditional Neuroimaging Methods and the Pathophysiology of mTBIthe Pathophysiology of mTBI
� Common CT and MRI Structural Brain Images – no evidence of damage
� When neuroimaging findings are present –outcome is “complicated mild TBI” - outcome more similar to moderate TBI
� Pathophysiology in blast injury as well as other etiologies of mTBI◦ Injured cells exposed to extreme changes in intracellular/ extracellular chemical environments◦ Disequilibrium – cells are susceptible to changes in blood pressure, flow characteristics◦ Cytotoxic edema develops◦ Estimated duration > 2 weeks ◦ Not evident in gross structural analysis
Pashek, 2010
Diffusion Tensor ImagingDiffusion Tensor Imaging
� DAI affects primarily white matter of the brain
� Diffusion Tensor Imaging (DTI)◦ Sensitive to white matter changes in the exchange of intracellular and extracellular water diffusion in brain tissue
◦ Allows visualization of orientation and direction of white matter fiber tracts

Diffusion Tensor Imaging (Mayer, Diffusion Tensor Imaging (Mayer, 2010)2010)
DTI Differential Diagnostic Potential� 22 patients with semi-acute mTBI (x = 12 days po)
� 21 healthy matched controls with 3-5 mos. Po follow-up
� DTI differentially distinguished between normal brains and brains of individuals with TBI
� Detect changes both early and late post-injury (Mayer et al., 2010)
� However, the researchers also noted some normalization of white matter changes 3-5 mos. post initial imaging (Mayer et al. 2010)
Pashek, 2010
Summary Summary -- NeuroimagingNeuroimaging
� Summary◦ DTI Appears to be better diagnostic indicator of
mTBI than CT or common structural MRI
◦ Global white matter pathology as determined by
DTI negatively related to cognitive impairment in all
cognitive domains (Kraus et al.)
◦ DTI changes noted over time may make it a neurological marker of mTBI recovery than clinical
imaging with MRI or CT
◦ More longitudinal studies needed (e.g., problem of
Dx in military)
Pashek, 2010
Neuroimaging Neuroimaging -- mTBImTBI
Other neuroimaging methods being explored demonstrating potential:
� Magnetic Resonance Susceptibility Weighted Imaging (MR-SWI)◦ “susceptibility” – degree of magnetization of a material in a magnetic field◦ good at detecting “microbleeds” (<5mm) common in DAI– venous blood and iron storage
� Magnetic Resonance Spectroscopy –allows non-invasive biochemical analysis of brain tissue for specific compounds (e.g., N-acetylaspartate, glutamate)

Repeatable Battery of Repeatable Battery of Neuropsychological StatusNeuropsychological Status
Commentary: Repeatable Battery of Neuropsychological Status (RBANS)
� Commonly used by neuropsychologists and now speech-language pathologists
� Good psychometric properties� However, the RBANs is a screening tool that is oriented more toward documentation of an impairment than a therapy evaluation◦ Does not allow for analysis of strategies as other tests (e.g., CVLT) do, e.g., organizational strategies in list learning
◦ Language portion is generally too easy to pick up subtle deficits or strategies
◦ Measures of attention (digit span, symbol digit task) do not get at higher level attention disorders, such as divided attention, distractibility
Pashek, 2010
Blast Injury Assessment ProfilesBlast Injury Assessment Profiles
� Anecdotal/Surprising Findings in Assessment of Blast Injury Patients with Blast Injury/Mild TBI by This Author◦ Extremely mild, often subclinical deficits
◦ Cognitive deficits apparent in testing in PTSD only cases
◦ Autobiographical memory/remote memory loss without retrograde amnesia in some individuals (if PTSD, working on autobiographical memory may not be recommended)
◦ Slowing of cognitive performance, in some instances comparable to that in older adults
◦ Varied divided attention deficits; vigilance often is quite good

Restoration vs. CompensationA Useful Controversy?
Pashek, 2010
“Restorative” Approach“Restorative” Approach
� Restorative Approach Perspective◦ Restorative Treatments (Coltheart – “Cognitivist Approach”– Based on model of the cognitive process and deficit and of neurological recovery mechanisms
◦ Focus on “experience driven plasticity”
◦ Cognitivists argue that compensatory approaches are atheoretical
◦ Approaches assume that teaching compensatory strategies may negatively affect potential for restoration of function (largely based on results of selected animal studies)
The jury is still out…
Pashek, 2010
“Compensatory” Approaches“Compensatory” Approaches
� Cognitive Prostheses◦ PDAs◦ Memory Books◦ Recorders◦ Medication Organizers
� Environmental Compensation◦ Family prompts◦ Labeling of the environment, etc.
� Internal Strategies◦ Word Substitution◦ Asking for help, etc.

Pashek, 2010 23
Can Some “Compensatory” Can Some “Compensatory” Strategies Facilitate Restoration? Strategies Facilitate Restoration?
Some “compensatory” approaches appear have some degree of restorative potential in some individuals, e.g.:◦ Circumlocution
◦ Use of imagery
◦ Self-talk to organize action
◦ “Re-organization Approaches e.g., “Gestural facilitation of speech,” “Treatment of Aphasic Perseveration” etc.
Pashek, 2010
Compensatory Approaches are Compensatory Approaches are Necessary Necessary
Compensatory Approaches� Pragmatically driven◦ Rehabilitation Funding◦ Early success◦ Functional need◦ Lack of strong neuropsychological models for many cognitive processes/deficits◦ Lack of evidence of detrimental effects in humans◦ Fairly strong evidence base for some interventions
