Neuropyschiatric Complications of TBI Flashcards
Is translational or rotational force worse?
Rotational
Can cause brainstem stretch
Where are the 2 most injured areas of the brain
Frontal lobe
Temporal lobe
3 types of primary brain injury
Contusion
Hemorrhage
Diffuse Axonal Injury
What causes secondary injury
Ischemia Excitotoxicity Inflammation Apoptosis Cell swelling
Mild TBI
- LOC time
- PTA time
- GCS Score
- < 30 mins
- < 24 hours
- 13-15
Moderate TBI
- LOC time
- PTA time
- GCS Score
- < 24 hours
- < 1 week
- 9-12
Severe TBI
- LOC time
- PTA time
- GCS Score
- > 24 hours
- > 1 week
- 3-8
Ratio between anterograde and retrograde amnesia
10:1
Lose more anterograde events

Complicated mTBI
When you meet the criteria for a mild TBI but you have some evidence of damage to your brain on neuroimaging
6 things involved in neurocognitive disorder
Complex attention Executive function Learning and memory Language Perceptual-motor Social cognition
3 primary symptoms of TBI
Mood symptoms
Sleep
Headache
Secondary symptoms
Balance Dizziness/vertigo Cognitive impariment Fatigue Tinnitus/noise intolerance
Chronic traumatic encephalopathy (CTE)
Progressive neurodegenerative disease
Repetitive is necessary but not sufficient for expression
Mood and behavious symptoms, motor signs
Delayed onset
Perivascular accumulation of tau in an irregular, focal, perivascular pattern at the depths of the cortical sulci
4 stages of CTE
1: no symptoms (but tau if building up)
2: rage, impulsivity, depression
3: confusion, memory loss
4: advanced dementia
Do people with a single concussion get CTE?
No!!
