[{'content': 'The finding in nerve conduction study to suggest axonal neuropathy among the following is: \nSelect and explain. \nA. Slow conduction velocities, B. Prolonged distal latency, C. Relatively preserved amplitude, D. Late potentials', 'role': 'user'}, {'content': 'Answer: D \nExplanation: To classify neuropathy into axonal degeneration or segmental demyelination the most helpful test is: NCS-Nerve conduction study. MUST KNOW: Findings to suggest axonal neuropathy in NCS: Relatively preserved distal latencies, conduction velocities, and late potentials. Fibrillations on needle EMG Findings to suggest demyelination in NCS: Slow conduction velocities, Prolonged distal latencies Late potentials Relatively preserved amplitudes Absence of fibrillations on needle EMG Ref: Harrison, Edition-18, Page- 3448', 'role': 'assistant'}]
