31

What is the triad of Kluver-Bucy syndrome? What lesion? Infection?

Triad:
- hyperorality
- hypersexuality
- disinhibited behavior
--> bilateral amygdala lesion
--> HSV-1 infection

32

What is the triad of Wernicke-Korsakoff syndrome? What causes this syndrome? What organ is affected?

Wernicke problems come in a CAN of beer:
- caused by thiamine (B1) deficiency and EtOH
- C: confusion
- A: ataxia
- N: nystagmus
- Mammilary bodies affected bilaterally

33

What lesion leads to hemiballismus? Ipsi- or contra- laterally?

Hemiballismus: STN, contralateral

34

What structures does PICA supply?

Lateral medulla:
1. vestibular nuclei
2. lateral spinothalamic tract
3. spinal trigeminal nucleus
4. nuclus ambiguus
5. sympathetic fibers
6. inferior cerebellar peduncle

35

When the partial pressure of oxygen falls below ___, cerebral perfusion pressure increases. (normal PO2 = ___).

When the partial pressure of oxygen falls below 50 mmHg, cerebral perfusion pressure increases. (normal PO2 = 100 mm Hg).

36

Where is Broca's area?

Intferior frontal gyrus of frontal lobe

37

Where is Wernicke's area?

superior temporal gyrus of temporal lobe

38

Which hematoma cannot cross the falx or tentorium?

subdural

39

Which structures does the lenticulostriate artery supply? Symptoms of stroke here?

striatum, internal capsule; contralateral hemiparesis/hemiplegia

40

Why might you hyperventilate a patient with acute cerebral edema?

decrease PCO2 --> vasoconstriction --> decreased cerebral perfusion --> decreased intracranial pressure

41

What are they symptoms of EtOH withdrawal?

6-12 h: ↑ autonomic activity, tremor, headache, N/V, anxiety

12-24 h: Alcoholic hallucinations

24-48 h: seizures
