Lower limbs injury in a child after car accident, lead to common peroneal nerve palsy, which results in gait abnormality due to weakness of ankle dorsiflexors. The gait that result from such injury is called

Correct Answer: C

Rationale: Steppage gait results from common peroneal nerve palsy, per neurology texts, with high stepping to clear the foot due to dorsiflexor weakness (foot drop). Shuffling is parkinsonian; tandem tests balance; toe walking spasticity. Steppagcompensation makes C the correct answer.

Correct Answer: B

Rationale: MRI is the study of choice for focal deficits, altered consciousness, or chronic headaches, per AAN, due to superior detail of brain parenchyma, ischemia, or masses. CT is faster for acute hemorrhage; X-ray skeletal; EEG seizures; LP infection. MRIs resolution make B the correct answer.

Correct Answer: D

Rationale: Generalized 3-Hz spike-and-wave on EEG indicatabsence seizure , per ILAE, common in childhood absence epilepsy, with brief staring spells. Atypical absence has slower (<2.5 Hz) waves; benign childhood focal spikes; aphasia language loss; West hypsarrhythmia. Classic EEG pattern makes D the correct answer.

Correct Answer: C

Rationale: Juvenile myoclonic epilepsy (JME) often requirlifelong treatment, per ILAE, with high relapse (>80%) off medication due to genetic myoclonic susceptibility. Simple and complex partial may remit; spasms resolve; Landau-Kleffner variable. JMpersistence makes C the correct answer.

Correct Answer: A

Rationale: Miller Fisher variant of Guillain-Barré presents with ataxia, ophthalmoplegia, and areflexia, per neurology, from anti-GQ1b antibodies. Flaccidity (B-C), sensory loss (B, D-E), and urinary retention (C-D) are atypical. Triad specificity makes A the correct answer.
