Comparison of the Neurological and Neuropsychological Functions Within Depressed Patients with and Without Suicidal Thoughts

Abstract

Objectives: This study was designed and conducted to compare the neurological and neuropsychological functions of depressed patients with and without suicidal thoughts. Methods: This research is a case-comparative study. A group of depressed patients visited NAJA Imam Sajjad Hospital between early August and late October 2016. According to the Morgan table, 66 individuals (33 with suicidal thoughts and 33 without) were selected for comparison with controlled variables in this examination. The Beck Depression Inventory (BDI), Neurological Evaluation Scale, and Wechsler Memory Scale (for neuropsychological function) were administered to all the participants. Data were analyzed using one-way analysis of variance (ANOVA), Scheffe follow-up test, and SPSS version 22 software. Results: The findings indicated that the group of depressed patients with suicidal thoughts showed poorer scores in neurological functions compared to the control group (P = 0.01). Furthermore, the control group scored higher than the depressed group with suicidal thoughts on the Wechsler Memory Scale (P = 0.05). Conclusions: The results suggest that depressed patients with suicidal thoughts exhibit worse performance in both neurological and neuropsychological functions compared to the non-suicidal group.
