  • REst
  • sleep
  • no alcohol/ drugs
    Avoid physical/ mental demanding activities that bring about symptoms )when symptoms return during activity, stop and rest, try again in 24-48hrs
  • Dont drive/ operate machines
  • Use pain meds as directed
  • Most recover in 7-10 days

Q

Second Impat Syndrome?

A

R2P too soon and they sustain second concussion before full recovery from first

Brain swells –> 50% mortality - disability or death

S&S
- dont lose consciousness but have a rapid decrease in function

17
Q

Post-Concussion Syndrome?

A

Symptoms lasting longer than expected (or new symptoms appearing)

18
Q

Repeated Cs?

A

Athletes with > 3 Cs have a decreased score on memory and neuropsychological tests vs athletes w/ out Cs.

19
Q

CTE?

A

Chronic Traumatic Encephalopathy

Repeated Brain Trauma
- memory loss, aggression, depressopm, explosive, PFC dysfunction
- Only detected after death
- P-tau proteins gather and tangle in brain

20
Q

NFL Game day protocol?

A

7 observable signs or a C
- if C identified = immediate removal from game and no same-day R2P

If player passes test they will be monitored for the rest of the game

Fines and loss of draft pics if not followed

21
Q

Canadian Guideline on C in Sport? (7 parts)

A

1) preseason education
2) Head injury recognition
3) Onsite Medical Assessment
4) Medical Assessment
5) C Management
6) Multidisciplinary C Care
7) R2P

22
Q

C Awareness Training Tool (CATT)?

A

AIM = standardize C recognition, diagnoses, treatment, and management

Based on principles from Zurich C Consensus Statement

Several tool kits for different people on their website

Training Modules

23
Q

What is and is not a C?

A

Not a brain bruise

  • Acceleration and Deceleration forces sustained by brain (lateral rotation force is most severe)
  • Stretch the axons of neurons (can cause rapid firing which is a seizure) –> Disrupts axons cytoskeleton = swelling/ dysfunction
  • Neurons can become temporarily disabled or permanently injured

-Cant detect w/ MRI/ CT scan unless vessels are damaged (but not usually the case
- Tho regulation of blood flow can be disrupted, there is not usually bleeding

24
Q

C. vs CTE?

A

CTE = progressive degenerative brain disease in those w/ Hx of repetitive brain trauma.

Build up of abnormal Tau-proteins -> aggregate around blood vessels (arteries)

25
Q

Symptoms of CTE?

A

Substantial mood change
- anger
- suicidal ideation
- depression
- headache
- explosive
- impulsive
- confusion
- memory problems
- progressive dementia

26
Q

Factors that can result in CTE?

A

Neuro-trauma
Substance use
chronic pain
athletic identity
mental health
