Depression Clinical Trial
Official title:
The Danish Neuropsychological Study of the Adverse Effects of ECT
The main purpose of this study is to investigate the adverse cognitive side-effects of electroconvulsive therapy (ECT). The second aim is to investigate the mechanisms of effect of ECT.
ECT has been the most effective treatment of depression for decades. Despite of this, neither the mechanism of action or side-effects are fully elucidated. The reason why some patients relapse shortly after remission is still not completely understood. Thus, there is a need to find predictors of the favourable clinical effect, relapse and side-effects. ECT is considered by professionals to be a safe procedure. Additionally, many patients do not consent to this treatment because they fear a permanent loss of memory or that they will contract a brain damage after the completed ECT series. Therefore, it is very important to examine whether ECT might have negative effects on the structure or function of the brain, using state of the art Magnetic Resonance Imaging (MRI) techniques. DANSECT is a prospective, observational follow-up study with the aim of examining why cognitive side-effects of ECT occur and potentially find predictors for whom they may affect by investigating the ECT-associated cognitive disturbances, structural brain changes and clinical outcomes. Second, DANSECT examines the mechanisms of effect of ECT. DANSECT comprises an ECT-group (30 patients) and a clinical control group (30 patients). The former consists of patients with depression receiving ECT, and the latter consists of matched patients with depression treated pharmacologically. The examinations will take place at three time-points; before, immediately after ECT or just before discharge, and 6 months after. DANSECT is a naturalistic clinical project. This means that the number of ECT sessions given to the patients in the ECT-group is up to the referring physician. The aim of DANSECT is to investigate the cognitive side-effects of ECT. Specifically, the research project aims to examine: 1. Prevalence, extent and persistence of adverse cognitive effects following ECT. 2. Associations between neuroimaging findings and cognitive changes following ECT. 3. Predictors of adverse cognitive effects of ECT. Hypotheses: 1. Consistency in autobiographical memories will be reduced over time in both study groups. However, the reduction will be significantly larger for the ECT patients after ECT compared to the control group. The group difference is expected to be present at both short-term and long-term. 2. Autobiographical memory deterioration is expected to correlate with volumetric changes of the hippocampi. 3. Processing speed, anterograde memory and executive functions will be temporarily deteriorated after ECT. The cognitive changes will correlate with volumetric brain changes and changes in structural connectivity. 4. Baseline atrophy, age, years of education and cognitive reserve will predict the cognitive side-effects following ECT. 5. Machine learning will reveal patterns and inference enabling the development of a predictive model of clinical and cognitive outcome after treatment with ECT, by combining neuropsychological tests, structural and functional neuroimaging (MRI) and other neurobiological measures. In addition, the aim of DANSECT is to investigate the mechanisms of effect of ECT. The secondary aims of the project are thus to examine: 1. Clinical, biochemical and neurobiological predictors of response to ECT 2. Clinical, biochemical and neurobiological predictors of relapse of depression after ECT 3. Biochemical and neurobiological mechanisms of response to ECT Hypotheses: 1. Smaller baseline hippocampal volume is associated with a larger post-pre reduction of depressive symptoms 2. Thinner cortical thickness predicts better clinical improvement 3. The cortisol trajectory before ECT is associated with clinical outcome 4. Elevated peripheral baseline VEGF is associated with a larger post-pre reduction of depressive symptoms 5. Baseline microRNA levels are associated with clinical outcome 6. A higher baseline structural connectivity predicts better clinical improvement 7. A larger post-ECT increase in hippocampal volume, cortical thickness, BDNF and VEGF predicts a lower risk of relapse within six months after an ECT series ;
