Concussion and Post-Concussion Syndrome Flashcards
Concussion:
International Consensus:
Complex pathophys. process affecting brain, induced by biomech forces
Concussion:
American Academy of Neurology:
Clinical syndrome of biomech. induced alteration of brain function, typ affecting memory and orientation, which MAY INVOLVE loss of consciousness (does not have to)
Concussion in terms of Severity
see pics
Concussion may/may not result in…
loss of consiousness
Resolution of clinical and cognitive sxs of concussion follows _____
sequential course
*small %→ post-concussive sxs may be prolonged
Simply put… concussion is _____
A form of TBI and should NOT be taken lightly!
Post-concussion syndrome
WHO:
Head injury usually suff. to result in loss of consiousness after which at least 3 of 8 common sx’s arise w/in 4wks
- Sx’s include:
- HA
- dizzy
- fatigue
- irritbility
- sleep probs
- concentration probs
- memory probs
- probs tolerating stress/emotional/alcohol
Why should PTs care about concussion?
Lots of Overlap!!!

Concussion in sports
usually…
High contact sports
Concussion + military
common injury exp’d in US military
Concussion and helmets
what should you remember?
Helmets do NOT protect from accel/decel forces→ only FOCAL injury
Concussion Risk Factors:
-
Previous concussion
- Hx concussion assocd w/ 2.5-8.5x higher risk of another
-
#, Severity, Duration
- higher→ predictor of prolonged recovery
- *Dizziness→ GREATEST PREDICTOR for recovery taking >21d
- Cognitive or migraine sxs req more recovery time
-
Migraines
- hx of pre-exist migraine HA= risk factor
- MAY BE assocd w/ prolonged recovery
Concussion risk factors
Sex
Females sustain more concussions
GREATER # and severity of sx’s and longer duration
Concussion risk factors
Age
Youth have more prolonged recovery + more susceptible
Concussion risk factors
sport, pos, style of play
Most common mech= player contact
full contact= highest risk
Signs and Sxs Concussion

S/S Concussion if concomitant C/S injury:
- Neck pain/stiff→ includes upper back
- HA
- dizzy
- tinnitus
- blurred vision
- sleep disturbs
- guarding+lmtd AROM C/S
- compensatory motions
- *sympathetic sx’s
What should be done if concussion suspected?

during-sport assess. for Concussion
SCAT5
Why is removal from activity so important if concussion suspected?
Second Impact Syndrome (SIS) ***
- When person who has NOT fully recovered from an initial concussion sustains a 2nd impact
- 2nd impact may be of a substantially smaller magnitude and may not even be directly to the head
- may occur in mins, days or weeks after initial concussion
- 2nd injury may result in catastrophic brain swelling and can lead to marked disability or death
Regulations in NJ for concussion:
in a nutshell…
- Any player exhibiting s/s concussion: LOC, HA, dizzy, confused, balance probs)→ immed. removed and not return until cleared to play
- “approp. healthcare pro” authorizes return-to-play is trained physician
Med. Exam for concussion
- Neuropsych. testing useful esp if baseline testing avail
- img’ing not sensitive enough to visualize damage→ can rule out more severe BI
- exam by phys.
