Functional remediation improves bipolar disorder functioning with no effects on brain-derived neurotrophic factor levels

The main aim of this study is to evaluate the impact of functional remediation (FR) in serum brain derived neurotrophic factor (BDNF) levels in euthymic adult patients with Bipolar Disorder (BD). A total of 128 participants were recruited at the Hospital Clinic of Barcelona. They were assessed at ba...

Sumario:The main aim of this study is to evaluate the impact of functional remediation (FR) in serum brain derived neurotrophic factor (BDNF) levels in euthymic adult patients with Bipolar Disorder (BD). A total of 128 participants were recruited at the Hospital Clinic of Barcelona. They were assessed at baseline and at the end of follow-up by the means of Hamilton Depression Scale (HAM-D), Young Mania Rating Scale (YMRS) and Functioning Assessment Short Test (FAST), as well as a clinical structured interview to collect clinical and demographic variables of interest. Blood samples were also collected to assess BDNF levels. After baseline assessment, patients received FR, Psychoeducation or treatment as usual (TAU). One hundred and two out of 126 participants finished the study distributed as follows: FR group (n = 39); Psychoeducation group (n = 47) and TAU group (n = 16). Longitudinal repeated-measures analyses addressing the treatment effect on BDNF levels showed non-significant differences between the three groups (Pillai's trace = 0.06; F(2,97)= 0.28; p = 0.75), suggesting no interaction between treatment allocation and time on BDNF levels. The results of this study suggest that FR has no effect on peripheral BDNF levels in euthymic patients with BD, despite the improvement in psychosocial functioning.
