Traumatic Brain Injury - Kanoff Flashcards
What is the definition of concussion?
Any neurological symptom due to an impulse to the brain
- doesn’t actually need to be direct trauma
- can be turbulent force that shakes the brain and causes damage
What does “RAM” stand for in the management of concussions?
R = Restrictions A = Accommodations M = Medications (symptom management)
How long does the average concussion last?
7-10 days
How long after a concussion is a person at high risk for addition concussion? Why?
10 days
Reduced reaction time, spatial awareness, and concentration.
What is the main goal in managing a concussion with restrictions?
- prevent new injury during recovery
- avoid risk taking
- progression to play
What is the most important aspect in the management of concussion symptoms?
Close follow up
What are some possible treatments in the management of concussion symptoms?

King-Devick
Where does brain atrophy start occurring in professional boxers?
Starts in thalamus, also happens in amygdala
What is the pathophysiology behind a concussion?
Disruption of cell function - ion channels leak.
- Calcium influx
- Cell dysfunction and damage
- Causes inflammatory response
- Axon disruption from the nerve cell
- Capillary disruption from the capillary network (micro bleeds)
- Energy mismatch, glucose not able to reach certain cells
What is the definition of post-concussive syndrome according to Dr. Kanoff?
Persistent symptoms referable to concussion, lasting beyond one month.
What is the difference between post-concussive syndrome and CTE?
- PCS = linked to discrete concussive event, symptoms wax/wane/resolve, non-progressive
- CTE = symptom-free interval with relatively high physical and cognitive functioning, progressive decline over years/decades
Is it possible that some people become unafraid of committing suicide?
Athletes may
-damage to amygdala wipes out fear of risky behavior
What is the recommendation on how many concussions is too many?
-4 concussive events within 4 years (each with symptoms lasting at least 7 days - assumes full recovery)
OR
-3 or more concussive events with progressively increasing deficits by BOTH duration and severity (assumes full recovery)
