6TH YEAR STATE EXAM WRITTEN STATE-
NEUROLOGY
• 1
NEU - 1.1
Epidural hematoma is caused by the rupture of:
A) middle meningeal artery
B) choroidal anterior artery
C) middle cerebral artery
D) superficial temporal artery
A) middle meningeal artery
The middle menigeal artery is the branch of external carotid
artery and runs between the dura mater and the temporal bone.
In case of bone fracture (temporal or parietal region), the middle
meningeal artery could be ruptured and arterial hematoma
develops quickly by compressing the ipsilateral hemisphere
resulting in first contralateral hemiparesis thereafter
somnolence, stupor, coma and finally herniation.
• 2
NEU - 1.2
The importance of external carotid artery is:
A) important for the blood flow supply of posterior scala
,B) important potential collateral source in case of ipsilateral ICA
occlusion
C) participates in blood supply of brainstem
D) its occlusion results in amaurosis fugax
E) supplies the frontobasal part of the brain
B) important potential collateral source in case of ipsilateral ICA
occlusion
The collateral circulation between the branches of external
carotid artery (facial, angular arteries etc.) and ophthalmic artery
(ICA branch) is important. In case of severe ICA stenosis or
occlusion the good collateral circulation can sustain
asymptomatic status. The reversed flow (extra-intracranial
direction) in the ophthalmic artery can be detected by
ultrasound.
• 3
NEU - 1.3
The ratio between carotid area and vertebrobasilar stroke:
A) 1:1
B) 1:3
C) 10:1
D) 1:10
E) 4:1
E) 4:1
,The carotid area strokes are 4-5x more frequent than the
vertebrobasilar ones.
• 4
NEU - 1.5
The role of sagittal superior sinus:
A) participates in the absorption of CSF
B) collects the blood of sagittal inferior sinus
C) transfers the blood of confluent sinus
D) collects the blood of transverse and cavernous sinus
A) participates in the absorption of CSF
The sagittal superior sinus collects the blood from the convexity
of the brain and participates in the absorption of CSF via
Pacchioni granulates.
• 5
NEU - 1.6
The risk of stroke in hypertension:
A) 2–8x
B) 0,3–3x
C) 2x
D) 50x
A) 2–8x
The hypertension increases the stroke risk by 2-8x
, • 6
NEU - 1.7
Symptoms of TIA, EXCEPT:
A) Transient unilateral blindness
B) Transient limb numbness
C) Transient aphasia
D) Transient loss of consciousness with epileptic seizure
D) Transient loss of consciousness with epileptic seizure
Transient focal deficits (unilateral blindness, aphasia, transient
focal numbness, transient paresis) are typical symptoms of TIA.
A transient loss of consciousness could be caused by quick
blood pressure decrease, arhythmias (pump-function), blood
glucose decrease or increase, and epilepsy but not by TIA.
• 7
NEU - 1.8
The ischemic stroke occurs frequently:
A) after waking
B) after going to bed
C) in the summer
D) in the afternoon
A) after waking
