In first-episode schizophrenia the advantage of new atypical neuroleptics compared to low-dose haloperidol as well as the indicated duration of neuroleptic maintenance treatment has still to be based on empirical evidence. Accordingly, a multi-center study on the optimization of acute and long-term treatment in first-episode schizophrenia is currently being(More)
OBJECTIVE Patients with schizophrenia are characterized by emotional symptoms such as flattened affect which are accompanied by cerebral dysfunctions. This study aimed at determining changes of mood-related neural correlates under standardized pharmacological therapy in first-episode schizophrenia. METHOD Using fMRI in a longitudinal approach, 10(More)
BACKGROUND After a first episode in schizophrenia guidelines recommend antipsychotic maintenance treatment (MT) for at least 1year. Recent RCTs on subsequent targeted intermittent treatment (IT) after stepwise drug discontinuation yielded noticeably higher relapse rates than during MT also in first-episode patients. Nevertheless, about 50% of patients(More)
BACKGROUND Aberrant brain activation during facial emotion discrimination has been described in chronic schizophrenia, while little is known about early stages of the illness. The aim of the current study was to investigate valence-specific brain activation of emotion discrimination in first-episode schizophrenia. These patients provide the advantage of(More)
An important risk gene in schizophrenia is D-: amino acid oxidase (DAAO). To establish if expression of DAAO is altered in cortical, hippocampal or thalamic regions of schizophrenia patients, we measured gene expression of DAAO in a post-mortem study of elderly patients with schizophrenia and non-affected controls in both hemispheres differentiating between(More)
Effectiveness has become more and more important as a comprehensive outcome measure for (long-term) treatment in schizophrenia. Early predictors to identify patients at a high risk for not succeeding the initiated treatment would be very useful. Discontinuation of the initiated treatment was used as criterion for effectiveness and patients' drug attitude(More)
OBJECTIVE Second-generation antipsychotics (SGAs) have proven superior to first-generation antipsychotics regarding relapse prevention, mainly in multiple-episode patients. Practice guidelines recommend SGAs as first-line treatment particularly in first-episode patients, although evidence for this group is still limited. Accordingly, the hypothesis of(More)
There is evidence for migrational disturbances in the entorhinal cortex (ERC) in schizophrenia that supports a neurodevelopmental origin of the disorder. Since impaired myelin basic protein (MBP) gene expression during the migration phase could lead to abnormalities in final laminar position, we performed layer specific measurements of MBP expression in the(More)
OBJECTIVE After acute treatment of the first illness episode in schizophrenia, antipsychotic maintenance treatment is recommended for at least 1 year. Evidence for the optimal subsequent treatment is still scarce. Targeted intermittent treatment was found to be less effective than continuous treatment at preventing relapse in multiple episode patients;(More)
OBJECTIVES Although schizophrenia affects both human genders, there are gender-dependent differences with respect to age of onset, clinical characteristics, course and prognosis of the disease. METHODS To investigate sex-dependent differences in motor coordination and activity as well as in cognitive and social behavior, we repeatedly tested female (n =(More)
