Abstract

Background: Despite increasing awareness of the extent and severity of cognitive deficits in major depressive disorder (MDD), trials of cognitive remediation have not been conducted. We conducted a 10-week course of cognitive remediation in patients with long-term MDD to probe whether deficits in four targeted cognitive domains, (i) memory, (ii) attention, (iii) executive functioning and (iv) psychomotor speed, could be improved by this intervention. Method: We administered a computerized cognitive retraining package (PSSCogReHab) with demonstrated efficacy to 12 stable patients with recurrent MDD. Twelve matched patients with MDD and a group of healthy control participants were included for comparison; neither comparator group received the intervention that involved stimulation of cognitive functions through targeted, repetitive exercises in each domain. Results: Patients who received cognitive training improved on a range of neuropsychological tests targeting attention, verbal learning and memory, psychomotor speed and executive function. This improvement exceeded that observed over the same time period in a group of matched comparisons. There was no change in depressive symptom scores over the course of the trial, thus improvement in cognitive performance occurred independent of other illness variables. Conclusions: These results provide preliminary evidence that improvement of cognitive functions through targeted, repetitive exercises is a viable method of cognitive remediation in patients with recurrent MDD.

  • Cognitive remediation therapies have proven effective in other psychiatric populations.

    “cognitive remediation therapies that have proven effective in other psychiatric populations (Bowie et al., 2013;Deckersbach et al., 2010;Elgamal et al., 2007;Kurtz, 2012;Wykes et al., 2011)”
  • Data from studies evaluating the impact of cognitive remediation therapy on cognitive performance in major depressive disorder indicate a positive effect on neuropsychological tasks of attention, verbal learning and memory, psychomotor speed, and executive function.

    “For example, data from studies evaluating the impact of cognitive remediation therapy on cognitive performance in MDD indicate a positive effect on neuropsychological tasks of attention, verbal learning and memory, psychomotor speed, and executive function [189, 190].”

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.
