What are common features of distal neuropathies such as diabetic polyneuropathy?

• A. Symmetric numbness/tingling of distal extremities, reduced reflexes, burning pain; management includes glycemic control, pain management, foot care.
• B. Unilateral numbness and rapid foot drop.
• C. Symmetric numbness with hyperreflexia.
• D. Pain only in proximal muscles.

Answer: (A)

Distal symmetric polyneuropathy from diabetes typically affects the longest nerves first, producing a stocking-glove pattern of sensory symptoms. The hallmark is symmetric numbness and tingling of the feet and hands, often accompanied by burning pain, with reduced or absent ankle reflexes on exam. Vibration and proprioception may be diminished as it progresses. Management focuses on three pillars: tighten glycemic control to slow progression, address neuropathic pain with appropriate medications (such as duloxetine or certain anticonvulsants) and provide patient education, and emphasize foot care to prevent ulcers given the loss of sensation. Keeping feet clean and dry, inspecting them daily, wearing properly fitting footwear, and seeking prompt treatment for any break in the skin are essential.

Other patterns don’t fit this picture: unilateral numbness with sudden foot drop points to a focal neuropathy like a peroneal nerve palsy; symmetric numbness with hyperreflexia suggests a central nervous system process rather than a distal peripheral neuropathy; pain limited to proximal muscles points toward a proximal myopathy or another non-neuropathic disorder.
