Abstract

Background Cross-sectional and meta-analytic studies showed that patients with bipolar disorder (BD) had neurocognitive impairments even during periods of euthymia. The aim of this study was to estimate the prevalence of BD patients with and without clinically significant cognitive impairments, as well as to analyze clinical and functional variables in these subgroups.Methods Hundred patients with BD and 40 healthy controls were assessed with an extensive neurocognitive assessment. Soft (some cognitive domain with a performance below 1.5 SD of the mean) and hard (at least two domains with values below 2 SD of the mean) criteria were utilized to define clinically significant cognitive impairments.Results Using both soft and hard criteria, the prevalence of clinically significant cognitive impairments was higher in people with BD than in healthy controls. 70% of patients only showed failures of small effect (d=0.21-0.35) in 2 measures of executive functions. Moreover, 30% of patients were indistinguishable from healthy subjects in terms of both neurocognitive and psychosocial functioning. On the contrary, 30% of the sample showed more severe cognitive deficits than those usually reported in literature and had the worst psychosocial functioning.Conclusions The fact that cognitive impairments are very heterogeneous among euthymic patients with BD could contribute to understanding differences in functional outcome. Theoretical and practical implications of these findings are discussed.

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.
