Relationship between theory of mind and metabolic parameters and functioning in patients with bipolar I disorder

Abstract

Purpose: We aimed to investigate the relationship theory of mind abilities with functionality and metabolic alteration in patients with bipolar disorder-1 (BD-1) during the remission period.
 Materials and Methods: This cross-sectional study is consisted of 68 patients with bipolar disorder-1 and 45 healthy controls. Sociodemographic form, Reading the Mind in the Eyes Test (RMET), Bipolar Disorder Functioning Questionnaire (BDFQ) were administered to the participants. Body mass index (BMI), waist circumference (WC), fasting plasma glucose (FG), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), total cholesterol (TC), triglyceride (TG) levels were recorded. 
 Results: There were significant differences between the patient group and healthy control group in terms of WC, BMI, HDL, LDL, TG. The results of independent samples t-test indicated a statistically significant difference in RMET score between the two groups with control group significantly higher than patient group. 
 Conclusion: Patients with BD-1 during the remission period have lower performance on theory of mind abilities and more alteration in metabolic parameters than healthy controls. Metabolic alteration and theory of mind impairment should be potential treatment target for BD
