BACKGROUND Although there are many P300 studies in depressive patients, only a few studies have focused on the effects of psychotic features in depression and of response to antidepressant treatment on P300. This study was designed to investigate possible differences in the P300 component of event-related potentials in depressed patients with and without(More)
Depressive patients with psychotic features demonstrate distinct biological abnormalities in the hypothalamic-pituitary-adrenal axis (HPA), dopaminergic activity, electroencephalogram sleep profiles and measures of serotonergic function when compared to nonpsychotic depressive patients. However, very few functional neuroimaging studies were specifically(More)
Reduced auditory P300 amplitude generally has been considered to be a trait marker of schizophrenia, independent of antipsychotic treatment and clinical symptoms. However, several seemingly well-conducted studies have found P300 amplitude to be a state marker correlated with clinical symptoms. Recent research on atypical antipsychotics indicate that these(More)
In this study, we aimed to investigate event-related potential (ERP) changes in panic disorder (PD) and generalised anxiety disorder (GAD) and to determine whether two disorders are different from each other in terms of endogenous potentials. A total of 35 outpatients who fully met DSM-III-R criteria for PD (8 males and 27 females) were included in this(More)
PURPOSE This study evaluated levels of metabolic control, resource use and quality of life in Turkish patients with type 2 diabetes initiated on insulin in routine care.
