Study on brainstem auditory evoked potentials in diabetes mellitus

Area of Science:

• Neurology
• Diabetology
• Neurophysiology

Background:

• Diabetes mellitus (DM) is a systemic disease with potential neurological complications.
• Brainstem auditory evoked potential (BAEP) assesses the integrity of the auditory pathway within the brainstem.

Purpose of the Study:

• To investigate changes in BAEP in patients with diabetes mellitus.
• To evaluate the utility of BAEP in detecting brainstem dysfunction in diabetic individuals.

Main Methods:

• A case-control study involving 50 diabetic subjects and 69 healthy controls.
• Diabetic patients were categorized by diabetes type, fasting blood sugar (FBS), and glycosylated hemoglobin (HbA1C).
• BAEP parameters, including wave latencies and interpeak latencies, were analyzed and compared between groups.

Main Results:

• No significant differences in BAEP findings were observed concerning FBS levels, HbA1C, or diabetes type.
• A significant association was found between diabetes and altered latency of BAEP waves III, IV, and V.
• Interpeak latencies I-III and III-V also showed significant differences in diabetic patients compared to controls.

Conclusions:

• Diabetic mellitus patients exhibit abnormalities in brainstem auditory evoked potentials.
• BAEP is a valuable tool for assessing brainstem function and detecting defects in diabetic patients.
