How can nerve conduction studies help in diagnosing peripheral neuropathy?

• A. By measuring blood pressure
• B. By assessing nerve fiber size
• C. By identifying the type of nerve affected
• D. By evaluating muscle tension

Answer: (C)

Nerve conduction studies are instrumental in diagnosing peripheral neuropathy because they provide insight into the functional status of the nerves in terms of their conduction velocity and response characteristics. By identifying the type of nerve affected—whether it is sensory, motor, or autonomic—clinicians can better understand the specific nature and origin of the neuropathy. This identification is crucial as different types of nerves can be impacted by various conditions, such as diabetes, trauma, or toxic exposure. Understanding which nerves are involved can help in formulating an effective treatment plan, predicting outcomes, and determining prognosis. For instance, if sensory nerves are primarily affected, it may suggest a different underlying cause than if motor nerves are involved. Therefore, this ability to categorize and specify the type of affected nerve is a vital part of the diagnostic process in peripheral neuropathy.
