Abstract

Background: Altered corticostriatothalamic encoding of reinforcement is a core feature of depression. Here we examine reinforcement learning in late-life depression in the theoretical framework of the vascular depression hypothesis. This hypothesis attributes the co-occurrence of late-life depression and poor executive control to prefrontal/cingulate disconnection by vascular lesions. Method: Our fMRI study compared 31 patients aged ⩾60 years with major depression to 16 controls. Using a computational model, we estimated neural and behavioral responses to reinforcement in an uncertain, changing environment (probabilistic reversal learning). Results: Poor executive control and depression each explained distinct variance in corticostriatothalamic response to unexpected rewards. Depression, but not poor executive control, predicted disrupted functional connectivity between the striatum and prefrontal cortex. White-matter hyperintensities predicted diminished corticostriatothalamic responses to reinforcement, but did not mediate effects of depression or executive control. In two independent samples, poor executive control predicted a failure to persist with rewarded actions, an effect distinct from depressive oversensitivity to punishment. The findings were unchanged in a subsample of participants with vascular disease. Results were robust to effects of confounders including psychiatric comorbidities, physical illness, depressive severity, and psychotropic exposure. Conclusions: Contrary to the predictions of the vascular depression hypothesis, altered encoding of rewards in late-life depression is dissociable from impaired contingency learning associated with poor executive control. Functional connectivity and behavioral analyses point to a disruption of ascending mesostriatocortical reward signals in late-life depression and a failure of cortical contingency encoding in elderly with poor executive control.

  • Depressed patients exhibit both hyposensitivity to rewards and oversensitivity to punishments, attributed to alterations in mesolimbic prediction error signaling, and may exhibit a constrained option space ('tunnel vision') during decision-making.

    “For instance, depressed patients exhibit both hyposensitivity to rewards and oversensitivity to punishments 96,97 , attributed to alterations in mesolimbic prediction error signaling 97-99 , and may exhibit a constrained option space ('tunnel vision') during decision-making 100 .”

  • In late-life depression, MDD patients showed significantly reduced increase of functional connectivity between the striatum and left operculoinsular cortex, right ventrolateral PFC, temporal gyrus, thalamus, and PCC in response to unpredicted reward vs unpredicted punishment compared with age-matched nondepressed controls.

    “In late-life depression, MDD patients showed significantly reduced increase of functional connectivity between the striatum and operculoinsular cortex (left), the ventrolateral PFC (right), temporal gyrus, thalamus, and posterior cingulate cortex (PCC) in response to unpredicted reward vs unpredicted punishment compared with age-matched nondepressed controls (Dombrovski et al., 2015).”

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.
