7Incidence of TBI
- 1.4 million reported incidents of TBI annually in
US, most- 75 to 95 are mild. - Division of Injury and Disability Outcomes
- http//www.cdc.gov/ncipc/pub-res/TBI_in_US_04/T
BI_ED.htm -
- 1.6 million military deployed to the Iraq and
Afghanistan conflicts. - 62 of those requiring medical evacuation from
the Iraq and Afghanistan conflict have TBI - 16 of returning military have had a reported
alteration in consciousness or LOC - 13-17 reported incidence of PTSD
- Am J Epidemiol 20081671446-1452
- Some estimates of incidence of TBI including
Blast injury as well as direct concussion and
trauma as high as 25 among returning military -
8 Monetary Costs of TBI
- Direct and indirect costs may exceed 60 billion
per year in the US - Costs of inpatient rehabilitation often exceed
100,000/patient - Outpatient cognitive rehabilitation approximately
20,000 to 30,000/patient - Employment drops from 69 to 31 by end of 1st
year of injury for civilian TBI - US civilian TBI result in 642 million in lost
wages yearly, 96 million in lost taxes yearly,
and 353 million in increased public assistance
expenditures. - Archives of Phys Med Rehab Vol 84, Feb 03, page
238-241
9Acute symptoms of Mild Brain InjuryDefinition
of Mild Traumatic Brain Injury According to the
American Congress of Rehabilitation Medicine
- 1. Any period of loss of consciousness
- 2. Any loss of memory for events immediately
before or after the accident - 3. Any alteration in mental state at the time of
the accident (e.g. feeling dazed, disoriented, or
confused), and - 4. Focal neurological deficit(s) that may or may
not be transient but where the severity of the
injury does not exceed the following - Post-traumatic amnesia not greater than 24 hours
- After 30 minuets, an initial Glasgow Coma Scale
score of 13-15 - LOC of 30 minutes or less
- Mild Traumatic Brian Injury Committee of the
Head Injury Interdisciplinary Special Interest
Group of the American Congress of Rehabilitation
Medicine. The definition of traumatic brain
injury. J Head Trauma Rehabil. 19938(3)86-87
10Mild TBI/PCS (post concussive syndrome)
- May not be a true history of LOC
- Hallmark manifestations of concussion confusion
and amnesia - 80 of those with mild TBI will experience some
symptoms of post-concussive syndrome - Risk of PCS does not correlate well with severity
of injury - Common clinical usage of both terms, PCS is a
subset of mild TBI
11Mild TBI mechanisms and pathology
- Coup and Contra-coup injuries
- -Goodman. Pathologic changes in mild head
injury. Semin Neurol 19941419 - Mild axonal injuries and rupture
- Potential for vessel oscillations to transmit
force of a blast to the Brain with subsequent
axonal neurofilament disruption and damage

from Iraq/Afghanistan
- 17 from Iraq showing signs of PTSD, major
depression or severe anxiety (90 involved in
direct combat) - 11 from Afghanistan showing signs of PTSD, major
depression or severe anxiety (31 were involved
in direct combat ) - Some reports of returning military units with
80 incidence of significant mental health issue
and 85 incidence of divorce - PTSD in Vets May Present as Substance Abuse.
www.internalmedicine news.com Dec 15,2008 - Emerging suicide issues
- Increased incidence of criminal arrests
(reported as high as 20-30) among returning
military from Iraq/Afghanistan
16Assessment of validity of Post Concussive
Syndrome
- Risk factors for Post concussive syndrome and
protracted recovery - Female gender
- Increasing age
- MVA /Assault, rather than sport related injury
- Pre-morbid depression or other psychiatric
illness - Co-existent PTSD
- Decreased social supports
- Issue of concerns for role of litigation
- Issue of coexistence of chronic pain complaints
- Issues
- -patients with psychiatric illness may be more
prone to injury - -patients with psychiatric illness may be more
prone to develop PCS after injury - -head injury may precipitate psychiatric disease
in susceptible individuals

22Seizures post TBI
- Post traumatic seizures occur in less than 5 of
mild or moderate TBI. - Increased frequency with more severe trauma.
- 50 occur within the first 24 hours of injury.
- 25 occur within first hour of injury.
- After the first hour, majority are simple partial
(motor) or focal with secondary generalization. - Early seizures increase the risk of post-
traumatic epilepsy by 4X - Anticonvulsants are not useful in prevention of
post traumatic epilepsy, but may be used to in
treatment of early seizures.
23Treatment of mild TBI
24Longitudinal Continuity of Care with Primary
PhysicianSymptomatic Treatment
- Frequent visits (often every 2 weeks)
- Address suicidal thoughts and psychotic ideation
early - Only one or two projects per visit
- Provide a Notebook Back-pocket Memory
- (VA may provide a PDA)
- Orchestrate care and network patients
- Set reasonable expectations Adaptation
- (LIMIT grief)
- Provide emotional support and
- attitudinal course corrections
- Provide necessary family and community Education
(with consent call them, if not with patient at
visit) - Celebrate success !

25Suggested Sequence of Symptomatic Treatment and
Rehabilitation for mild TBI
- First Priority SLEEP
- Pain and Headache
- Emotional Concerns Anxiety and DepressionPTSD.
- Sensory Disturbance Visual, Acoustic,
Equilibrium - Fatigue
- Education Family and Employer
- Visual and Vestibular Rehab
- Cognitive Rehab

C Burgess MD
26TBI Management post- traumatic Headache
- Use Low Dose pharmacologic therapy!
- Often worse after mild TBI occur in 25 to 78
of patients with mild TBI - Use localized therapy or treatment when possible
(lidocaine patch, NSAID patch, cortisone
injection, or physical therapy) - Types of Headache
- mixed,
- tension (75),
- migraine,
- occipital and trigeminal neuralgia,
- TMJ,
- positional,
- analgesic overuse,
- low CSF pressure,
- cluster,
- hemicrania continua
27Pharmacologic management of headache associated
with TBI
- Pharmacologic Management
- Prophylactic
- Tricyclic antidepressants Amitriptyline and
Nortriptyline (Amitriptyline 10mg-250mg qd) - Calcium channel Blockers Verapamil (initiate
Verrapamil SR 120mg qd.) - B blockers Nadolol (20mg qd 40mg bid),
Propanolol SR (80mg-160mg qd) - also Timolol,
metoprolol, and atenolol - Valproate (125mg bid increasing to 250mg bid
- Gabapentin (900 to 1200 mg daily)
- Topamirimate (25 mg to 125 mg daily)
- Naproxen (250 mg to 500 mg bid)
- Tizanidine (1-2mg po qhs, may increase to 8 mg
qhs)
28Management of TBI Headache (Continued)
- Propanolol or amitriptyline in combination or
alone have a response rate of up to 70 - Dihydroergotamine and metaclopramide IV in
repetitive dosing in an inpatient setting may be
effective - Triptans may be used for acute Migraine
- Indomethacin may be used for paroxysmal
hemicrania and hemicrania continua (25 mg tid
increase to 50 mg tid) - Occipital nerve block with local anesthetic and
corticosteroid for occipital headache is highly
effective for greater occipital neuralgia. - Analgesic overuse headache is common.
29Management of Sensory Disturbance post TBI
- Avoidance of overstimulation prior to or during
performance of tasks - Photophobia
- Use of dark and transitional glasses.
- Careful lighting (fluorescent an issue)
- Referral Behavioral optometrist
- Diplopia may result from injuries to CN III, IV,
and VI. - Anosmia and Hyposmia impaired taste and smell
due to injury to olfactory filaments at the
cribiform plate. In 2/3 of patients is a
permanent injury (usually permanent if still
present at 1 year). Attention needed to avoid
weight alterations and gastric irritation.
Avoidance of gas appliances.
30Management of Sensory Disturbance (continued)
- Hyperacusis Use of specialty ear plugs in noisy
environment. Referral Audiologist - Example of available Westone ES 49 earpiece
protection for musicians - Disequilibrium and Vertigo
- Vestibular rehabilitation. Referral ENT and
specially trained physical therapist. - Consider pharmacologic use of Meclizine or
Clonazepam (disadvantage is sedation and
suppression of adaptive learning). - Encourage regular coordinated movement (dance,
tai-chi, etc.). Avoid sports prone to new
injuries! - Driving can be an issue rehabilitation
facilities often have driving assessment services
and retraining. - NO ETOH!
31Post Traumatic Vertigo/Dizziness
- Mechanisms of Vertigo
- Direct injury cochlea or vestibular structure
esp. with sensorineural hearing loss or fracture
of temporal bone - Labyrinthine concussion (vertigo plus ataxia)
maximal at onset and abating within weeks - BPPV (benign paroxysmal positional vertigo) due
to shearing and displacement of otoconia. Can
be a hiatus of weeks or months between TBI and
development. - Perilymphatic fistula due to rupture of oval or
round window. Unilateral SN hearing loss with
persistent vertigo and ataxia characteristic - Other post-traumatic Menieres, brainstem
ischemia with vertebral artery dissection,
epileptic vertigo, and migraine related vertigo. - Mechanisms of non-vertiginous dizziness is often
cervical - Aberrant afferent input from positional
proprioceptors in C- spine - Overstimulation of cervical sympathetic nerves
- Compromised vertebral arterial flow
-
32Management of Fatigue and lack of Concentration
- Appropriate sleep, diet and limited exercise.
Respect for biorhythms - Frequent rest periods
- Avoidance of excessive environmental stimulation
- Pharmacologic management
- Wellbutrin SR/XL (Budeprion)100mg q am 300mg
q am - Provigil (modinafil) 100mg q am - 200 mg q am
and afternoon - Occasional use adderal, concerta, dexedrine,
ritalin - May exacerbate irritability, anger, and sleep
issues
33Favorite pharmacologic choices for mild TBI C J
Burgess, MD
- Nortriptyline 10-25 mg qhs for headache, sleep,
pain and potentially anxiety - Plus zolpediem (Ambien) 5-10 mg, or ramelteon
(Rozerem) 8 mg if needed for sleep - Citalopram (Celexa) 10-20mg, escitalopram
(Lexapro) 5-10mg, or Vanlafaxine (Effexor XR)
37.5-75 mg for anxiety and depression, agitation,
emotional lability and to improve sense of well
being. - Modinafil (Provigil) 100-200 mg or Budeprion SR
(Wellbutrin) 100-150 mg qam for alertness and
reduced fatigue. - Clonazepam (Klonopin) .25 - .5mg up to tid for
equilibrium issues and vertigo if meclizine
fails. Use short term as a bridge to vestibular
rehab. - Donepezil (Aricept) 10mg qd if memory issues are
profound and persistent. - Topamax 25mg to 100mg qd if headaches remain
intractable.
34Cognitive Rehabilitation
- Continuing controversy regarding short-term and
long term benefits to outcome of early
intervention with cognitive and behavioral
therapy. - Differences in study design including patient
selection, nature of intervention, and measures
of performance have hindered assessment of
cognitive interventions. - Interventions often delivered in an individual
setting based on deficits identified with
Neuro-psych testing (full evaluation often
involves 4 -6 days of testing).
35Cognitive Evaluation of mild TBI
- Neuropsychological Testing
- Vulnerable domains to TBI
- Attention
- Working memory
- Processing speed
- Reaction time
- Not associated with gross deficits of
intelligence and memory - Findings can be confused with those of pain
syndromes and medication effects as well as
psychological illness - May be helpful in differentiating TBI from
alternative diagnosis. -

effects of traumatic brain injury on cognitive
functioning. Int Rev Psychiatry 2003 15341
36Expectations
37Expectations after Mild TBI
- 10-15 of mild TBI cases have persistent symptoms
beyond one year - Iverson. Outcome from mild traumatic brain
injury. Curr Opin Psychiatry 2005 18301 - 80 of those with post traumatic headache improve
significantly during the first year. - 15-31 of those with post traumatic headaches
persist for greater than 3 years and are likely
permanent. - Packard RC. Post-traumatic Headache permanency
and relationship to legal settlement. Headache.
199232496-500
38Expectations after mild TBI
- Pre-morbid personality and educational
characteristics may play a role in recovery from
mild TBI. Pre-morbid physical limitations, prior
head injury, psychiatric illness, and older age
may limit recovery. - Most improvements occur in the first one to two
years after injury, but patients may continue to
report progress (improvement in cognition and
memory as well as a decline in physical symptoms)
as late as five years post injury. - Prompt diagnosis, appropriate post-injury
expectations, and continued support of family,
employer and community lead to better long term
outcomes after injury.
39Instructions for Employers and Families
- Frequent rest periods
- Variable scheduling
- Careful sequencing (prioritize)
- Avoidance of unnecessary stimulation
- Noise, multiple sources of sound
- Harsh Light (fluorescent lights potentially
problematic) - Hectic motion-filled environment
- Fumes (issue with Migraine)
- Emotional circumstances
- Calm environment
- Redirection and rest if actions/verbalization are
inappropriate - Early identification of problem areas for
treating MD/rehab team/transition coach. Use the
notebook or back-pocket memory. - Strong feedback on success
40Lessons learned from mild TBI patients
- Family physicians have pleotropic effects.
- Physician and patient expectations are critical
to recovery. Set an obtainable expectation at
each and every visit. First steps first. - Dont allow a mild or moderate TBI to become the
defining moment of the patients existence. So
what? Is a critical concept to a successful
reboot by a patient with TBI. - The human brain is plastic.
- Humor has amazing therapeutic value. So does
expression of Art, Poetry, Music, and movement. - Allow patients to share their successes and
experiences with other similar patients of the
practice if support groups are not plentiful.
Dont be intimidated by HIPPA.
41Lessons learned, continued
- Recruit help from any available source including
family and children, libraries, literary
volunteers, community centers, etc. Elementary
educational materials may be a critical tool for
those not eligible for cognitive rehab. Office
staff are often an amazing resource. Patients
have a hard time asking for help for themselves. - Support with enthusiasm any potentially
achievable educational or recreational objective
or project that interests the patient. The
process of participation, effort and study will
help heal the patient often creating detours
for injuries sustained. Have the patient
volunteer if they are not employable. - Prevent second injuries.
42Call for Immediate Action
- Availability of appropriate primary MD evaluation
and longitudinal care for our homecoming
military. - Availability and timely referral for appropriate
diagnostic testing (?universal application for
those with known trauma or blast exposure) - Availability of outpatient rehabilitation
programs, group and individual - Availability of psychological support and
treatment - Availability of support for transition to
peacetime civility - No adverse sequela to seeking treatment
Avoidance of long term military career impedance - Availability of special care by the Judicial
system
43Brainstorming
- Establish community and base military TBI support
groups and group rehabilitation programs.
(Establish location and leader) Potential for
formal group psychotherapy. Funding for
educational programs. - Establish community and base intervention teams
for potential evolving crisis circumstance. A
need for time out short term residences (not
the hospital, the local bar, or a jail cell) - Special legal channeling within the court system
for those with military transition problems. - Evolution of transition teams and coaching
to promote successful transition from battlefield
to family and employment. Programs for
individuals remaining in active military careers
as well as those transitioning to community. May
vary by region and service. - Adequate formulary and device support for
treatment. - Encourage local bars to offer a few tasty brain
drinks (not a shirley temple).
