Post-Concussion Syndrome
• Mild TBI account for 75% all TBIs.
• Post-concussion syndrome is a complex disorder in
which a combination of post-concussion symptoms —
such as headaches and dizziness — last for weeks and
sometimes months after the injury that caused the
concussion.
• In most people, post-concussion syndrome symptoms
occur within the first seven to 10 days and go away
within three months, though they can persist for a year or
more.
Post-Concussion Syndrome
Symptoms Include:
Headache Irritability Memory problems
Dizziness Anxiety Impaired sustained
Vertigo Depression attention
Tinnitus Personality Increase distractibility
Hearing loss Slowed processing speed
Smell/taste changes
change
Blurred vision Word retrieval problems
Sleep disturbance
Diploplia Fatigue
Photophobia Phonophobia

A Historical Perspective
Physician’s Survey of Post Concussive and Whiplash Syndromes, 1993:
•Mailed a survey
questionnaire to 750 FP,
475 Neurologists, 425
Neurosurgeons, and 625
Orthopedists.
•Physicians did not feel
that Post Concussive
Symptoms made up a
“well-defined
syndrome.”
A Historical Perspective
Physician’s Survey of Post Concussive and Whiplash Syndromes, 1993:
• Reasons for this skepticism:
– Chronic post concussive
symptoms were not
predicted by injury
“severity.”
– Chronic post concussive
symptoms did not appear
to develop or resolve in
any particular order.
– A somewhat
disproportionate number
of patients were involved
in litigation related to
injury.
– It must be psychological
vs. neurologically organic.
A Historical Perspective
Physician’s Survey of Post Concussive and Whiplash Syndromes, 1993:
“Even though
they have
symptoms, the
sooner they
ignore them and
get on with their
lives, the faster
they will
improve.” --NS
A Historical Perspective
Physician’s Survey of Post Concussive and Whiplash Syndromes, 1993:
However… Physicians were
beginning to recognize a that “A
growing body of evidence supports
the organicity of PCS.”
Definition of mild TBI in 1993:
“Any alteration in mental state at
the time of the accident (feeling
dazed, disoriented, or confused).”
Assessments were still not
sensitive to TBI and majority of
physicians continued to assess
with clinical neurological
examination and CT scans.
A Historical Perspective
Physician’s Survey of Post Concussive and Whiplash Syndromes, 1993:
“Litigation and
compensation
are the main
issues.
Emotional
instability— lack
of goal
orientation and
direction in one’s
life are major
factors.” --FP
―Syndrome‖ Semantics
“Indicators of a syndrome
include consistent
symptom linkage and
coupling of symptom
response to treatment.
Consistency of clinical
presentation is not readily
supported by the current
clinical studies of this
population.”
―Syndrome‖ Semantics
TWO CAMPS:
1)―Post Concussive Syndrome a neurobiological
and pathogenic process specific to TBI.
2)Post Concussive Syndrome is not a true
syndrome, but is a myriad of co-occurring
symptoms seen commonly after brain injury, each
initiated by the same event (TBI) but produced by
different underlying mechanisms.
Does it REALLY matter??
Pathophysiology
of Mild TBI:
• Oppenheimer found evidence of axonal injury in
5 patients with minor or trivial injuries, using
immunostaining for amyloid precursor protein as
a marker for axonal injury.
• Blumberg et. al. found multifocal axonal injury in
five individuals who had sustained very mild
injuries with brief periods of unconsciousness.
Pathophysiology
of Mild TBI:
• Animal Models: cats (fluid percussion) and primates
(angular acceleration devices) suggest that mild TBI is
associated with axonal injury.
• Although axotomy occurs at the time of injury, delayed
axotomy also contributes to the outcomes. The process
involves initial changes to the permeability of the
axelomma (axonal membrane), which leads to secondary
deafferentiation.
Imaging Studies in MTBI
• Newer imaging techniques such as
PET, SPECT, fMRI, MRS,and pre-
pulse MRI show promise in detecting
subtle sequelae of MTBI.
• See also Electrophysiological
measures such as EEG, QEEG, EP,
ERP.
• Better imaging validates cognitive
testing.
Secondary Gain

Why Energy Management?
• The Brain is the only organ
in the body that requires
sleep
• Although the brain
represents only 2% of the
body weight, it receives
15% of the cardiac output,
20% of total body oxygen
consumption, and 25% of
total body glucose
utilization.
The Coping Hypothesis
• Fatigue is present in up to 70% of mTBI patients.
• Fatigue can be related to mental effort necessary to
overcome attention deficit and slowed processing
(―coping hypothesis‖).
• Fatigue can also be related to endocrine or metabolic
disturbances in the brain following MTBI
• ―TBI individuals expend greater psychophysiological
costs in order to maintain stable performance over
time, and that these costs are associated with
subjective increases in fatigue.
Bushnik et. al. (2007)
Ziino & Ponsford (2006)
Evidence for Energy Management
Existing studies generally have involved individualized
counseling, providing information about expected symptoms
Treatments need to focus on
and suggested coping strategies, and in some cases regular
follow up.

Evidence for Energy Management
• Fatigue, depression, pain, and organic sleep problems are
much more prominent in individuals with TBI than in
controls. Cause of fatigue following TBI is not only organic
(pushing through pain and PCS with de-compensation
exacerbates organic fatigue)
• Post TBI fatigue is correlated with health-related quality of
life and overall quality of life, but in studies, it is not always
related to participation in major life activities (Because rest
is not intuitive).
• Post traumatic brain injury fatigue cannot be accounted for
by co-morbid variables such as depression, etc.
Baumann et. al. (2007).
Bushnik et. al. (2007)
Cantor et. al. (2008)
Evidence for Energy Management
Why do SLPs need to give specialized awareness training
to mTBI patients?
• Pts may not acknowledge, or may minimize, the severity of
acquired deficits for up to several years following mTBI.
• Patients don’t realize functional deficits before they return to
full function; need awareness in effective early intervention.
• Pts require “rest” education because it is not intuitive for
them in the initial month they are out of work. As Kent points
out, ―the deeper and more comprehensive an individual’s
awareness becomes, the more the person is able to apply
their understanding to new and different situations.”
• ―There is a high prevalence of sleep disorders (46%) and of
excessive daytime sleepiness (25%) in subjects with TBI.‖
Sleepy subjects may be more cognitively impaired than
comparable non-sleepy subjects with TBI, yet be unaware of
problems.‖ Flashman L & T McAllister, 2002
Kent 1999 JHTR
Castriotta et. al. 2007
Evidence for Energy Management
• Compared with controls, TBI patients reported
significantly poorer sleep quality. Objective
sleep recording showed that TBI patients
showed an increase in deep (slow wave)
sleep, a reduction in rapid eye movement
sleep and more frequent night time wakings.
• Injury severity is not predictive of sleep
impairment.
• Findings contribute to a growing body of
evidence that sleep is involved in the
physiologic processes underlying neural
recovery.‖ In order to ensure maximal
cognitive recovery (in addition to teaching
compensation techniques), fatigue should be
closely managed by rehab team.
Parcell et. al. (2008)
Evidence for Energy Management
What are the most common PCS symptoms
that SLPs indirectly treat through energy
conservation education and awareness
training?
• Poor memory, sleep disturbance, and fatigue are
among the most commonly reported symptoms
(fatigue and memory compensation are strongly
correlated).
• Findings in studies suggest a relationship
between subjective fatigue (mental fatigue) and
impairment on tasks requiring higher order
attentional processes (e.g. auditory working
memory).
Lundin et. al. (2006)
Siino C & Ponsford J (2006)
Summary
• Injury severity does not predict severity or
presence of PCS.
• PCS create the need to cope or decompensate,
which expends mental and physical energy.
• To add insult to injury, majority of Pts with TBI
experience sleep disturbance.
• Energy management and awareness training
have been shown to be effective in managing
post concussive symptoms, and subsequently,
improving cognition.

Essential Components of Treatment
• Energy management training
• TBI education
• Awareness training
• Cognitive remediation
• Customized goals for daily responsibilities,
work &/or school
• Regular interdisciplinary communication
Immediately After
Concepts of Energy TBI
Management Returning to
Life and Activities
• Rest & breaks allow brain
to heal. Premorbid
• Resource allocation—
Multitasking is not helpful.
• Overtly train client how to
scale back (may seem counter intuitive to
―getting better‖).
• Recovery curve and awareness is ―up &
down‖ & help client to expect it & accept it.
• The ―energy pie‖ will be smaller than normal
for some time.
Energy Management
Stage One--Scaling back
First: TBI education
- Pathophysiology
-Typical symptoms (related to
RPQ)
-Definition of rest & rationale
-Resource allocation
-Recovery curve
-Interplay between cognition &
PCS
-Involve family/friends
Energy Management
Stage One--Scaling back
• Use of energy management form & log
- Client writes activities & symptoms daily.
- May find rating scale helpful.
- Teach & reinforce sleep hygiene.
(Planning and awareness).
- Add in hourly rests/breaks (or more).
- Possibly add in naps.
- Initially have client focus on observing
relationship between activities, rest &
cognition.
Energy Management
Stage One--Scaling back
• Review energy log in detail during initial
treatment sessions
-Analyze progress with meds, rest, sleep,
breaks, microbreaks
-Look for small, subtle ―nuggets‖ of what
lessens or exacerbates symptoms
• Be an active, patient listener
Energy Management
Stage One--Scaling back
• Train client to be own detective
-Interpret symptoms
-Identify triggers & look for patterns
-Minimize symptoms with behavior change
• Address awareness
-Train client to recognize changes before symptoms
worsen
• Validate symptoms & difficulty scaling back
-Provide support & help with problem solving
Awareness Training
• Train client to be own expert.
• Client lists how she thinks she’ll do on a task & what
strategies she’ll use.
• Complete task.
• Client gives own assessment of performance, change
in any symptoms & effectiveness of strategies.
• SLP gives assessment, comparison of discrepancies,
feedback.
• Self awareness often comes through ―failures.‖
Energy Management
Stage Two--Stabilization
• Start to plan more specific time & activity
management once you find patterns
• Further customize rest, breaks, microbreaks
• Continue to limit triggers
• Remove self from tasks/locations earlier (Plan B
or ―escape routes‖)
• Goal is symptom stability/resolution within this
current stage
• Note: All of the above concurrently address
energy conservation and cognition.
Energy Management
Stage Three--Rebuilding
• Client lists tasks that were taken
off plate
• Work together to add these back in (modify to
follow energy conservation)
• Have client describe plan in detail
• Change only one factor at a time when
incrementally adding in tasks
• May need to add in “recovery” days
• Be stable in symptom control before adding
more activities
Adjustment/Acceptance
• Provide continuous TBI education
to normalize the experience
• Provide support & encouragement
especially in light of how invisible
this type of injury is
• Help them accept the
changes/length of recovery
• Help them adjust to reduced
quality of life, scaled back activity
level
Interdisciplinary Team
• ―All this time I just thought I was
going crazy.‖
• ―I wish I had known this stuff two
years ago!‖
Common patient complaints
• Physical Symptoms: headaches, dizziness,
sleep disturbance, fatigue, photo- and/or
phonophobia
• Cognitive changes: forgetfulness, slow thinking,
word-finding problems
• Mood changes: irritability, frustration,
depression, anxiety, restlessness
Patients always need
• Medical or medication management
• TBI education
• Energy management guidance and
awareness training
• Counseling and support
Patients frequently need
• Cognitive rehabilitation, including
compensatory strategies
• Occupational therapy
• Clinical psychological services
• Coordination, liaison, and counseling
concerning return to work/school
Patients sometimes need
• Rehabilitation for visual issues (e.g.
convergence insufficiency or scanning
disorders)
• Physical therapy, including treatment for
vestibular issues
• Help with support system management (e.g.
disability paperwork, financial issues, sharing of
information)
The Interdisciplinary
Treatment Team
Success of rehabilitation is
dependent on an integrated,
collaborative approach due to
interlinked symptom etiology and
maintenance factors
Benefits of team rehabilitation
• Simultaneously addresses variety of patient’s
symptoms and needs
• More efficient coordination of services through
the course of recovery
• Message reinforcement and repetition
• Diversified, distributed practice for patients,
increasing likelihood of generalization of skills
and strategies
• Group problem-solving and support for clinicians

A word about
overlap/duplication of services
• Areas of potential overlap with SLP role:
– Occupational therapy (external memory
aids, cognitive testing, cognitive treatment,
and functional compensatory strategies for
cognitive issues)
– Clinical psychology (supportive counseling)
– Neuropsychology (cognitive testing)
– All (energy management)
A word about
overlap/duplication of services
• Recall the benefits
– Message reinforcement
– Diversified, distributed practice of skills and
techniques
• Take care to
– Make scope of practice distinctions in
documentation and goal setting (e.g. OT talks
about planners in terms of ADLs; SLP talks
about planners in terms of cognitive
processes)
