AIDP clinical features include which of the following?

• A. Progressive symmetric weakness starting in legs and spreading proximally
• B. Focal weakness in a single limb
• C. Predominant sensory loss with intact strength
• D. Chronic progressive weakness without areflexia

Answer: (C)

Acute inflammatory demyelinating polyneuropathy (AIDP) presents as an acute or subacute, motor-dominant polyneuropathy with symmetric, ascending weakness often starting in the legs and moving upward, accompanied by reduced or absent reflexes (areflexia). Sensory symptoms like tingling or numbness can occur but are usually not the dominant feature; motor weakness is the key finding. The option describing predominant sensory loss with intact strength does not fit this motor-focused, rapidly progressive pattern. The other descriptions imply a focal or chronic process, which also don’t match AIDP. So the hallmark scenario is ascending weakness with areflexia, not sensory-predominant or chronic presentations.
