Exploring the relationship between vitamin D and mania: correlations between serum vitamin D levels and disease activity

AbstractBackground: Several studies suggest an association between hypovitaminosis D and mood disorders including major depressive disorder, seasonal affective disorder and premenstrual dysphoric disorder. On the other hand, there is not enough study about acute manic episode and hypovitaminosis D. This data insufficient zone led us to study on whether vitamin D deficiency is associated with acute manic episode and has an impact on disease activityMethods: Thirty-one patients with bipolar disorder in remission, 26 patients with acute manic episode and 40 healthy controls with no major psychopathology were recruited in this study. Hamilton Depression Rating Scale (HAM-D), Young Mania Rating Scale (YMRS) and the Clinical Global Impression – Severety scale (CGI-S) were used to evaluate disease activity. Total vitamin D (D2 + D3) values were measured.Results: Patients in acute manic episode had significantly lower (p = .002) vitamin D serum concentrations than healthy controls (respectively 15.16 ± 7.48 and 2...
