Assessment of cognitive domains in major depressive disorders using the Cambridge Neuropsychological Test Automated Battery (CANTAB): Systematic review and meta-analysis of cross-sectional and longitudinal studies
(Elsevier BV, 2025-02) Arnone, Danilo
Cognitive difficulties are known to persist after remission of symptoms and to affect psychosocial functioning and quality of life. Cognitive function, measured with the Cambridge Neuro-psychological Test Automated Battery (CANTAB), is a reliable approach to measure cognitive function in major depression. This systematic review and meta-analysis appraise cross-sectional and longitudinal studies that used specific CANTAB tests to measure cognitive function in major depression and the effect of treatment (PROSPERO ID: CRD42022355903). 1212 studies were identified and 41 were included, 1793 patients and 1445 healthy controls. Deficits in executive functions were detected with the Stocking Of Cambridge (SOC) 'number of problems solved with minimal number of moves' and 'subsequent thinking time', Intra-Extra Dimensional Set Shift 'number of trials to complete the test', Spatial Working Memory 'strategy score' and 'between errors score', Spatial Span. Memory deficits were detected with Paired Associates Learning 'number of total errors', Pattern Recognition Memory (PRM) '% of correct answers' and 'response latency', Spatial Recognition Memory '% of correct answers', Delayed Matching To Sample (DMS) '% of total responses'. Impaired attention was detected by Rapid Visual Information Processing 'response latency' and probability to detect target'. Mental and motor responses increased when Reaction Time was measured. SOC 'number of problems solved with minimal number of moves', PRM 'response latency' and DMS '% of total responses' improved after a course of treatment. A range of variables including year of publication, age, IQ, severity and duration of illness influenced cognitive changes. The presence of significant cognitive deficits requires novel targeted interventions.
Efficacy of Lamotrigine in the Treatment of Unipolar and Bipolar Depression: Meta-Analysis of Acute and Maintenance Randomised Controlled Trials.
(2025-10-21) Arnone, Danilo
Background/Objectives: Lamotrigine has been widely investigated in the treatment and prevention of the emergence of symptoms of depression in unipolar and bipolar depression. This work systematically appraises published and unpublished double-blind randomised controlled trials of lamotrigine to provide up-to-date guidance on the use of lamotrigine in the presence of depressive symptoms. Methods: Systematic searches identified 32 randomised controlled trials, of which 24 were included in the meta-analysis, involving 2257 patients and 2320 controls. Results: Evidence supports the use of lamotrigine in the acute phase of bipolar depression in monotherapy vs. placebo (SMD: 0.155; CI: 0.005-0.305) in the absence of significant heterogeneity and small study effects. In the prophylaxis of bipolar depression, lamotrigine reduced the risk of the emergence of depressive symptoms (RR: 0.78; CI: 0.63, 0.98) and prolonged the duration of symptoms survival (RR: 1.59; CI: 1.19, 2.11) compared to placebo, with no evidence of publication and small study bias. Lamotrigine was not found to be superior to lithium in the acute treatment and prophylaxis of bipolar depression. In the treatment of unipolar depressive episodes, with the inclusion in the analyses of three unpublished studies, lamotrigine was not superior to placebo in monotherapy and as adjunct treatment. There were no maintenance studies in unipolar depression. Conclusions: There is evidence supporting the use of lamotrigine in monotherapy as acute and prophylactic treatment of bipolar depression. Evidence of the use of lamotrigine in unipolar disorders is lacking. PROSPERO registration ID: CRD42025633709.
