1. A young adult presents with progressive gait difficulty and spasticity. The clinician suspects a hereditary basis and wishes to examine family members. Which of the following conditions listed in the chapter is specifically noted as having a genetic basis?
- ACervical spondylosis
- BGuillain-Barré syndrome
- CAcute transverse myelitis
- DHereditary spastic paraparesis
Show answer
D. Hereditary spastic paraparesis The text states that some types of myopathy, motor neuron disease, peripheral neuropathy, spinocerebellar degenerations, and hereditary spastic paraparesis have a genetic basis.
2. A 60-year-old man has leg weakness and reports a distinct sensory level at the umbilicus, below which he has numbness. He has no cortical signs such as astereognosis or agraphesthesia. Where is the lesion most likely located?
- ANeuromuscular junction
- BCerebral cortex
- CPeripheral nerve
- DSpinal cord
Show answer
D. Spinal cord The text states that sensory loss below a particular segmental level on the trunk suggests a spinal cord lesion, whereas distal sensory changes in limbs favor peripheral nerve lesions.
3. Two patients present with progressive leg weakness due to myelopathy. Patient A has significant back pain accompanying the weakness, while Patient B has no pain at all. Based on this distinguishing feature, which statement is most accurate?
- APatient B's myelopathy is more likely due to a compressive lesion
- BPatient A's myelopathy is more likely due to a hereditary cause
- CPain is equally likely in metabolic and compressive myelopathies
- DPatient A's myelopathy is more likely due to a compressive lesion
Show answer
D. Patient A's myelopathy is more likely due to a compressive lesion The text states that pain preceding or accompanying myelopathy suggests a compressive lesion, while its absence favors a metabolic or hereditary basis.
