ABSTRACT
Purpose:
Higher homocysteine (HHcy) levels have been detected in bipolar disorder (BD) patients, and BD patients show circadian rhythm disorders even during remission. Here, we determined the homocysteine (Hcy) levels and chronotype of patients with BD during remission and investigated whether this was related to the clinical course of the disease. Materials andmethods:
In total, 80 BD outpatients were included. Clinical evaluation was conducted using the Hamilton Depression Rating Scale (HDRS), Young Mania Rating Scale (YMRS), Pittsburgh Sleep Quality Index (PSQI) and the Morningness-Eveningness Questionnaire (MEQ). Hcy, folic acid, vitamin B12 levels and protein consumption the day before clinical evaluation were measured.Results andconclusions:
HHcy was found in 11 patients (8.8%), most of whom were males (n = 8, 72.7%). During the course of BD, patients with HHcy had significantly more mixed episodes than patients without HHcy (p = .007, z = -2696). In addition, patients with HHcy had significantly lower MEQ scores than patients without HHcy (p = .04, t = 2018). There was no significant difference in chronotype between patients with and without HHcy. The HHcy group had significantly lower levels of vitamin B12 (p = .003, t = 2870). There were no statistically significant differences in daily protein intake and folic acid levels between HHcy and non-HHcy groups. Our study showed a significant relationship between the number of mixed episodes and HHcy. In terms of potential confounds, patients who abused alcohol were excluded, but alcohol consumption was not evaluated. This result should be considered in BD and should be evaluated in larger samples of BD patients.Palavras-chave
