SOMATIC NEUROPATHY IN DIABETES MELLITUS.

Area of Science:

• Neuroscience
• Endocrinology
• Clinical Neurology

Background:

• Diabetes Mellitus is a chronic condition associated with significant risk of developing neuropathy.
• Early detection and severity grading of diabetic neuropathy are crucial for effective patient management.
• Peripheral nerve involvement in diabetes can occur even before clinical symptoms manifest.

Purpose of the Study:

• To correlate the clinical severity of diabetic neuropathy with the extent of nerve conduction abnormalities.
• To investigate the diagnostic utility of nerve conduction studies in identifying preclinical diabetic neuropathy.
• To assess the impact of disease duration and patient age on neuropathy development.

Main Methods:

• Studied 100 patients with Diabetes Mellitus (70 with and 30 without clinical neuropathy).
• Performed nerve conduction studies on 48 patients, assessing median, peroneal, and sural nerves.
• Measured latency, amplitude, and motor/sensory nerve conduction velocities under standardized conditions.

Main Results:

• Neuropathy incidence increased in patients over 40 years and with disease duration exceeding two years.
• Sensory nerve conduction velocity was more affected than motor velocity; abnormalities found in 14/21 patients without clinical neuropathy.
• Reduced motor nerve conduction velocity correlated with moderate/severe neuropathy grades and was more pronounced in lower limbs.

Conclusions:

• Nerve conduction abnormalities are indicative of peripheral nerve involvement in diabetic neuropathy, even in preclinical stages.
• Nerve conduction studies effectively correlate with the clinical severity of established diabetic neuropathy.
• Early detection via nerve conduction studies aids in managing diabetic neuropathy and preventing complications.
