Neurology Flashcard Deck - 10 Cards
Flashcard 621: _____ syndrome presents with
- Horner's syndrome
- Contralateral loss of pain & temperature sensation in torso/limbs
- Ipsilateral loss of pain & temperature sensation in face
- CN X palsy (dysphagia)
Answer: Lateral medullary (Wallenberg)
Flashcard 622: _____ syndrome presents with
- Ipsilateral CN VII palsy
- Contralateral loss of pain & temperature loss in limb/torso
- Vertigo, nystagmus, ataxia
Answer: Lateral pontine
Flashcard 623:
What factor best predicts the outcome in encephalitis?
_____
Answer: Early initiation of IV aciclovir; mortality is ~10-20% if treated promptly, ~70-80% if left untreated
Flashcard 624: What symptom/clinical sign helps differentiate meningitis, encephalitis from brain abscesses?
_____
Answer: Focal neurological deficits
Flashcard 625: Which cerebral artery supplies most of the lateral surface of the cerebral hemisphere?
_____
Answer: Middle cerebral artery
Flashcard 626: Patients my refer to TIAs as "_____"
Answer: mini-strokes
Flashcard 627: The most helpful non-invasive imaging modality to differentiate a brain abscess from a necrotic tumor is _____.
Answer: Diffusion-Weighted MRI (DWI)
Extra: On MRI:
- **Brain Abscess:** Shows **restricted diffusion** (bright on DWI, dark on ADC) due to the high viscosity of pus.
- **Necrotic Tumor:** Typically shows **facilitated diffusion** (dark on DWI, bright on ADC).
Flashcard 628: In suspected encephalitis, a _____ should be performed prior to lumbar puncture if there are signs of increased intracranial pressure or focal neurological deficits.
Answer: CT scan
Extra: A CT scan is performed prior to Lumbar Puncture (LP) to rule out space-occupying lesions (SOL), midline shift, or obstructive hydrocephalus, which could lead to brain herniation during the procedure. Indicators for CT before LP include papilledema, focal neuro deficits, new-onset seizures, or significantly impaired consciousness.
Flashcard 629: Which cerebral artery supplies the language centers (Broca area, Wernicke area)?
_____
Answer: Middle cerebral artery
Flashcard 630:
~50% of brain abscesses originate from _____
Answer: infection of adjacent structure (e.g. otitis media, mastoiditis, dental infection, sinusitis)
