Abstract

OBJECTIVE: To compare the effects of right unilateral (RUL) electroconvulsive therapy (ECT) and algorithm-based pharmacologic treatment (APT) on neurocognitive function in treatment-resistant bipolar disorder depression. METHOD: Inpatients with DSM-IV-TR-diagnosed, treatment-resistant bipolar depression, who were acutely admitted to 1 of the 7 clinical study centers in Norway, were recruited from May 2008 to April 2011 into a prospective, randomized controlled, 6-week acute treatment trial. General neurocognitive function was assessed with the MATRICS Consensus Cognitive Battery (MCCB), and retrograde memory for autobiographical events was assessed with the Autobiographical Memory Interview-Short Form (AMI-SF) before and shortly after (mean = 23.5 days) a trial with either RUL brief-pulse ECT (mean dose = 233.3 mC) or APT. RESULTS: Seventy-three patients entered, and 39 (nECT = 19, nAPT = 20) completed. Both groups showed improvements in all MCCB domain scores, with no significant differences between the study groups (no interaction effect: F₁,₃₇ = 1.52, P = NS). Improvements in neurocognitive performance were significantly correlated with reductions in depression ratings posttreatment. The AMI-SF score was significantly lower (based on consistent answers from pre- to posttreatment) in the ECT group (72.9%) than in the APT group (80.8%, P = .025), indicating reduced consistency in autobiographical memory after ECT. CONCLUSIONS: General neurocognitive function was unaffected by RUL brief-pulse ECT treatment and positively related to improved mood in bipolar depression. Autobiographical memory consistency was reduced in patients treated with ECT. The results suggest that ECT can be used in treatment-resistant bipolar depression without compromising general neurocognitive function. The clinical relevance of reduced autobiographical memory consistency in the ECT group requires further investigation. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00664976.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
