Abstract

Executive dysfunction (ED) in geriatric depression (GD) is common, predicts poor clinical outcomes and often persists despite remission of symptoms. Here we develop a neuroplasticity-based computerized cognitive remediation-geriatric depression treatment (nCCR-GD) to target ED in GD. Our assumption is that remediation of these deficits may modulate the underlying brain network abnormalities shared by ED and depression. We compare nCCR-GD to a gold-standard treatment (escitalopram: 20 mg per 12 weeks) in 11 treatment-resistant older adults with major depression; and 33 matched historical controls. We find that 91% of participants complete nCCR-GD. nCCR-GD is equally as effective at reducing depressive symptoms as escitalopram but does so in 4 weeks instead of 12. In addition, nCCR-GD improves measures of executive function more than the escitalopram. We conclude that nCCR-GD may be equally effective as escitalopram in treating GD. In addition, nCCR-GD participants showed greater improvement in executive functions than historical controls treated with escitalopram.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Two proof of concept studies showed that computerized cognitive remediation improved both depressive symptoms and executive functions in late-life major depression and in the DED syndrome more than the comparison conditions.

    “Two proof of concept studies showed that such training improved both depressive symptoms and executive functions in late-life major depression179 and in the DED syndrome180 more than the comparison conditions.”

    From Mechanisms and treatment of late-life depression (2019) · cites this paper as [180]

  • Clinical research indicates that cognitive training, mindfulness meditation, and aerobic exercise reduce depressive symptoms and improve executive dysfunction or neuroticism in late-life depression.

    “clinical studies suggest cognitive training, mindfulness meditation, and aerobic exercise improve depression symptoms and executive dysfunction or neuroticism in LLD 17, 40, 41.”
  • Among older adults with late-life depression who had not responded to at least one antidepressant, 30 hours of computerized cognitive training over one month reduced depression more than three months of escitalopram.

    “Findings revealed that 30 CCT hours completed over one month resulted in a greater decrease in depression compared to treatment with escitalopram over three months.”

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.
