NCT03295305

Brief Summary

PRETEC-ABC aims to assess the effect of a new form of cognitive remediation, Action-Based Cognitive Remediation (ABCR), in patients with bipolar disorder in remission on cognition, and to assess the neural assays for treatment effects with the purpose of identifying a neural biomarker for pro-cognitive effect. It is hypothesized (i) that ABCR vs. a control treatment has a beneficial effect on cognition in remitted patients with bipolar disorder remission. It is hypothesized (ii) that this treatment-associated improvement of cognition translates into better functional capacity at a six months follow-up assessment (secondary outcome). Finally, as an exploratory measure, it is hypothesized that ABCR will produce an early change in frontal activity and that this activity will correlate with ABCR-associated improvements in cognitive function.
