Comparison of Active Memory, Inhibition of Response and Dimensions of Nature and Character in Patients with Type 2 Diabetic Retinopathy and Normal Counterparts in Tabriz

Studies have shown that cognitive function is impaired in patients with diabetic retinopathy. The aim of this study was to determine and compare active memory, inhibition of response and dimensions of nature and character in patients with type 2 diabetic retinopathy and normal counterparts in Tabriz.

The present investigation was a cross-sectional descriptive-comparative study. The statistical population of this study were 160 patients with type 2 diabetic retinopathy with an age range of 32 to 55 years referred to Tabriz Diabetes Center in 2019. Based on the available sample, 80 patients with type 2 diabetic retinopathy were selected in Tabriz hospitals and with 80 Ordinary people became equal, in addition to the questionnaire of the dimensions of nature and the character of Cloninger, they answered the tasks of memory and inhibition. Data were analyzed using multivariate, Levene's Test and Kolmogorov-Smirnov analysis of variable statistical tests.

Data analysis indicated that there was a significant difference between the scores of patients with type 2 diabetic retinopathy and normal people in active memory, response inhibition and the dimensions of nature and character. This means that in memory and inhibition, the response of the normal group is better than the condition of patients with type 2 retinopathy, and also in the components of reward dependence, perseverance, cooperation and self-care, the performance of the normal group is better than the retinopathy type 2 (p<0.01). However, retinopathy patients scored higher than normal subjects (p<0.01) and no significant differences were observed between the two groups in the component of regression and self-guidance (p<0.05).

According to the results of the present study, it can be said that diabetic retinopathy patients are more passive in terms of personality and weaker in terms of memory than their counterparts and have less inhibition and more impulsive behavior in their behaviors. As a result, it is recommended that cognitive rehabilitation training be considered for these patients.
