Abstract

Studies suggest that neuropsychological measures may provide prognostic information regarding SSRI treatment response, yet it is unclear which specific cognitive domains are the most effectual predictors. The aim of this study was to characterize the cognitive profile associated with SSRI nonresponse using a comprehensive set of neuropsychological tests. Participants (N = 32) met criteria for current major depressive episode. Assessment followed pre-treatment medication washout. Clinical response was measured after 3-month open-label SSRI treatment. Groups did not differ by demographic characteristics, intelligence or depression severity. Responders outperformed nonresponders across all cognitive domains, with the largest differences observed in executive, language and working memory functions. Results indicate poorer global cognitive functioning is predictive of treatment nonresponse. Deficits were most pronounced in tests demanding greater mental search and manipulation rather than speeded motor output. Cognitive slowing may mediate the working memory and executive function deficits found in nonresponders. These findings can inform exploration for pharmacogenetic endophenotypes.

  • The most frequent findings include small to moderate deficits in attention, working memory, learning, processing speed, and executive functions in major depressive disorder.

    “The most frequent findings include small to moderate deficits in attention [22], working memory [25], learning [10], processing speed [26], and executive functions [27].”
  • Some pilot studies show that cognitive deficits in major depressive disorder patients may predict non-response to treatment with selective serotonin reuptake inhibitors or dual serotonergic-noradrenergic reuptake inhibitors.

    “Furthermore, some pilot studies show that cognitive deficits in MDD patients may predict non-response to treatment with selective serotonin reuptake inhibitors (SSRIs) or dual serotonergic-noradrenergic reuptake inhibitors (SNRIs), indicating that poor performance in selected cognitive domains may define a patient subgroup that requires complex or additional treatment [21–23].”

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.
