Head Trauma, Cohen Flashcards Preview

Year 2 neuro exam 2 > Head Trauma, Cohen > Flashcards

Flashcards in Head Trauma, Cohen Deck (26):
1

population affected most by head trauma

men
elderly now on medications like anti platelet anti coagulation

2

general injury causing head trauma

acceleration deceleration
strike by object
cerebral edema

3

Minor head trauma
moderate
severe

minor is 9-13 on glascow scale
mod: 8-12
major: <7

4

components of glascow scale

eye movement 4
verbal response5
motor response 6

5

Volume of skull limited by

brain
CSF
blood in aa and vv

6

Cushing reflex

hypertension and bradycardia

7

most dangerous traumatic hemorrhage in brain

ruptured aneurysms

8

contusions

small ares bleeding in brain itself
usually near surface sometimes deeper

9

type of bleed from tearing of bridging veins

subdrual hematoma

10

subdurals more common in who

elderly with more room between brain and skull

11

acute vs chronic subdural hematoma

chronic is seen 21 days since onset
acute if within 72 hours

12

Sx subdural hematoma

HA
confusion
hemiparesis
seizures
CN III palsies

13

CT MRI subdural hematoma

crescent

14

Tx if patient has clear deficits and subdural is over 3 mm thick

surgical drainage
small burr holes or full craniotomy

15

do all subdural hematomas shrink

some can expand and soon deteriorate

16

what causes delayed hydrocephalus

loss of CSF earlier

17

epidural hematoma

dangerous!!
can have skull fracture
middle meningeal tear
compress brain more quickly

18

Hx epidural hematoma

suffered serious injury with loss of consciousness immediately

19

Lucid interval

lost consciousness wake up then lose again
time between is lucid interaval

20

lens shape bleed

epidural

21

Tx epidural

surgical drainage!!

22

Concussion

head trauma producing reversible decline in brain function even without loss of consciousness

23

Head CT for concussion

when loss of consciousness, persistent HA or significant neurological deficit

24

Post concussive syndrome

persistent HA
light headedness
depression
poor concentration
irritability

25

chronic traumatic encephalopathy

irreversible brain disease from multiple minor head injuries like concussions
Tau aggregation along Cx
atrophy widened sulci and large ventricles
septum pellucidum and corpus callosum damaged

26

early Sx CTE

irritability, anger, aggression, impulses, memory loss and inattention
lack of insignt, inability to manage affairs, loss of language skills
frontotemporal dementia
looks like PD or ALS
