BACKGROUND We compared the attention abilities of a group of first-episode schizophrenia (FES) patients and a group of healthy participants using the Attention Network Test (ANT), a standard procedure that estimates the functional state of three neural networks controlling the efficiency of three different attentional behaviors, i.e., alerting (achieving and maintaining a state of high sensitiv...

OBJECTIVE Previous morphometric studies are suggesting altered cortical thickness mainly in prefronto-temporal regions in first episode schizophrenia. In an extension of these earlier studies, we used an entire cortex vertex-wise approach and an automated clustering for the detection and exact quantification of cortical thickness alterations in first episode schizophrenia. METHODS A group of ...

We thank Harvey et al for bringing our attention to the frequency of self-harm during first-episode psychosis. Our data (which we are submitting for publication) indicates an even greater concern in this population. A retrospective review of all psychotic patients admitted to a child and adolescent psychiatry unit from 2003 to 2006 showed that out of 1500 cases reviewed, 102 patients below the ...

Animal word list generation (ANWLG) was administered to 47 first-episode schizophrenia (FES) participants and 31 controls. Fifty-nine left temporal lobe epilepsy (LTLE) participants were included as a comparison group with known temporal lobe damage and expected semantic deficits. Semantic knowledge was assessed with the Association Index (AI), a measure of the semantic relatedness of all conse...

Studies with chronic schizophrenia patients have demonstrated that patients fluctuate between rigid and unpredictable responses in decision-making situations, a phenomenon which has been called dysregulation. The aim of this study was to investigate whether schizophrenia patients already display dysregulated behavior at the beginning of their illness. Thirty-two first-episode schizophrenia or s...

BACKGROUND Misidentification phenomena, including the delusion of 'imposters' named after Joseph Capgras, occur in various major psychiatric and neurological disorders but have rarely been studied systematically in broad samples of modern patients. This study investigated the prevalence and correlated clinical factors of Capgras' phenomenon in a broad sample of patient-subjects with first-lifet...

BACKGROUND Schizophrenia shortens life, e.g. through suicide and obesity-related diseases such as type 2 diabetes mellitus. It is assumed that medications play a major role, but most of the evidence for this comes from studies poorly controlled for variables such as lifestyle and medication status. AIMS To determine whether schizophrenia is associated (independently of medication) with the de...

OBJECTIVES This study employed the Future Thinking Task (MacLeod et al., 2005, Br. J. Clin. Psychol., 44, 495) to investigate whether future-directed thinking in first-episode psychosis is significantly different from that of matched controls, and to identify its correlates in this patient group. DESIGN Cross-sectional, mixed-model, case-control design. METHOD Participants were 30 patients ...
