An Electrophysiological Comparative of Auditory and Visual Reaction time among Diabetics and Non-Diabetics- A Case Control Study

Abstract

Background: Type 2 diabetes is a pandemic;  visual and auditory reaction time were used as  tools to detect neuropathy a common complication of diabetes so that we could prevent further damage to nerves. Objectives: To measure and compare visual and auditory reaction time between Type -2 diabetics on oral medication and non-diabetics. Material and Methods:  A case control study was done  and they were enrolled based on detailed questionnaire and informed consent was obtained .The study was conducted in the month of July 2019 which included 40 Type 2 diabetic subjects from a tertiary care hospital. Visual Reaction time and Auditory reaction time were measured. PC1000Hz reaction timer was used to measure auditory and visual reaction time SPSS software (trial version 22.0) was used for analysis. Results:The mean age of type 2 diabetic subjects was 49.6 years and that of control 44.4 years cases and controls were age matched. The visual reaction times was significant with p value = .001 and for auditory reaction time p value =.001. Conclusion:Auditory and visual reaction was prolonged in type 2 diabetics on oral medication when compared with non-diabetics of same age group. This can be due to neuropathic changes in diabetes.
