Major depressive disorder (MDD) is characterized by disturbances of mood and affect, but also by a distinct pattern of psychomotor and cognitive deficits such as motor retardation and impaired executive functioning. An important aspect of executive functioning is performance monitoring, i.e., a continuous checking whether intended action goals have been(More)
INTRODUCTION Action monitoring has been reported to be disturbed in Major Depressive Disorder (MDD). Well-known markers for this action monitoring process are the error negativity/error-related negativity (Ne/ERN) and error positivity (Pe), both event-related potentials (ERP) generated in the anterior cingulate cortex. This study aims to explore the impact(More)
BACKGROUND Psychomotor retardation (PR) is one of the core features in depression according to DSM V (1), but also aging in itself causes cognitive and psychomotor slowing. This is the first study investigating PR in relation to cognitive functioning and to the concomitant effect of depression and aging in a geriatric population ruling out contending(More)
BACKGROUND There is a relative scarcity of studies on major depressive disorder that use objective assessment methods to explore the psychomotor effects of antidepressants. Striatal dopaminergic disturbances are known to be involved in the pathogenesis of major depressive disorder that is associated with psychomotor retardation. Because of its additional(More)
Disturbed internal performance monitoring has been repeatedly demonstrated in schizophrenia. Along with internal monitoring, efficiently processing external task-relevant performance feedback that goes unnoticed by the internal monitoring system is crucial for adequate performance. It is unknown whether external monitoring is disturbed in schizophrenia and(More)
Most research points to cognitive slowing in chronic fatigue syndrome (CFS), although there have been negative reports. The present study is one of few that examines fine motor processing and the inhibition of automatic responses in a well-characterised CFS population. A total of 35 female CFS patients without current major depression and 25 female controls(More)
BACKGROUND Studies comparing chronic fatigue syndrome (CFS) and major depressive disorder (MDD) reported similarities as well as differences between the two disorders. However, whereas psychomotor symptoms have been studied extensively in MDD, such research in CFS is more limited. Moreover, the few studies that compared cognitive and motor performance in(More)
BACKGROUND The aim of the study is to assess the severity of psychiatric stigma in a sample of personality disordered adolescents in order to evaluate whether differences in stigma can be found in adolescents with different types and severity of personality disorders (PDs). Not only adults but children and adolescents with mental health problems suffer from(More)
