Background: Major depressive disorder (MDD) is associated with increased heart rate and reductions in its variability (HRV) – markers of future morbidity and mortality – yet prior studies have reported contradictory effects. We hypothesised that increases in heart rate and reductions in HRV would be more robust in melancholia relative to controls, than in patients with non-melancholia. Methods: A total of 72 patients with a primary diagnosis of MDD (age M: 36.26, SE: 1.34; 42 females) and 94 con...

Abstract While depression has been associated with relatively greater right than left frontal cortical activity – a neurophysiological marker reflecting greater activation of the withdrawal system – contradictory findings have been reported. It was hypothesised that melancholia would be associated with relative right frontal activation, in comparison to non-melancholia and controls. We collected 2-min of resting-state, eyes closed, electroencephalographic activity from a total of 237 participant...

Objective:Depressed patients display a variety of deficits in neuropsychological function, and contradictory findings in the literature may be due to disorder heterogeneity. The aim of this study was to examine the impact of severity, subtype and symptoms on cognitive control.Methods:Neuropsychological function across a range of cognitive control tasks was examined in melancholic (n = 65) and non-melancholic depressed patients (n = 59) relative to controls (n = 124). The relationship between sub...

Objective: Major depressive disorder (MDD) is associated with deficits in executive cognitive function, including inhibitory control. However, inconsistencies have been found across studies. Depression is a heterogeneous disorder and these inconsistencies may therefore relate to heterogeneity in relatively small samples.Method: Here we sought to examine event-related potentials (ERPs) during a cognitive Go/No-Go task in melancholic (n = 60) and non-melancholic depressed patients (n = 54) relativ...

Major depressive disorder is often considered to be a homogenous disorder that changes in terms of severity; however, the presence of distinct subtypes and a variety of presenting symptoms suggests much heterogeneity. Aiming to better understand the relationship between heterogeneity and diagnosis we used an exploratory approach to identify subtypes of depression on the basis of clinical symptoms and neuropsychological performance. Cluster analysis identified two groups of patients distinguished...

Objective: Two reported genetic polymorphisms related to the production of brain-derived neurotrophic factor (BNDF) and reuptake by the serotonin transporter (5-HTT) appear to contribute to depression in combination with stressful life events. The aim of the current study was to investigate the contribution of early life stress (ELS), BDNF (Val versus Met alleles) and 5-HTT polymorphisms (L versus S alleles) to melancholic (n = 65) and non-melancholic depression (n = 59).Methods: A mediation app...

Abstract The current review provides a qualitative assessment of the efficacy of dialectical behaviour therapy (DBT) as adapted for adolescents. The aim was to assess the efficacy of DBT compared to usual methods in the treatment of adolescent mental health symptoms, inclusive of suicidal ideation and self-harm. Computerised databases including Medline and PsycINFO were accessed and knowledgeable informants in the area of DBT were contacted. Inclusion criteria required the studies to be clinical...
