BACKGROUND The catechol-O-methyltransferase (COMT) Val(108/158)Met polymorphism of the dopamine system is essential for prefrontal cortex processing capacity and efficiency. In addition, dopaminergic neurotransmission is also associated with the sensory gating phenomenon protecting the cerebral cortex from information overload. It is however unclear if COMT(More)
Several polymorphisms of the transcription factor 4 (TCF4) have been shown to increase the risk for schizophrenia, particularly TCF4 rs9960767. This polymorphism is associated with impaired sensorimotor gating measured by prepulse inhibition--an established endophenotype of schizophrenia. We therefore investigated whether TCF4 polymorphisms also affect(More)

The development of a brief intervention for nursing home residents combining physical activation and reminiscence therapy in order to reactivating apathic residents and(More)
PURPOSE Here we evaluate an interdisciplinary occupational and sport therapy intervention for dementia patients suffering from apathy. SUBJECTS AND METHODS A prospective, controlled, rater-blinded, clinical trial with two follow-ups was conducted as part of a larger cluster-randomized trial in 18 nursing homes in Berlin. n=117 dementia patients with(More)
INTRODUCTION In linkage and association studies the DTNBP1 gene has been identified as a major susceptibility gene for schizophrenia. Reduced expression of DTNBP1 was found in the hippocampus and prefrontal cortex in post mortem brains of schizophrenic patients. In vitro and animal models provide evidence that the DTNBP1 gene product dysbindin modulates the(More)
We report on the treatment of a patient suffering from dementia with Lewy bodies who initially presented with severe neurological and psychopathological symptoms. After treating the patient with levodopa and clozapine, these symptoms remitted.
Background: There is a high prevalence of obsessive-compulsive symptoms (OCS) in patients with schizophrenia. Antipsychotic treatment, especially duration and type of substance, is suspected to increase or even cause OCS. Methods: We examined in a naturalistic cross-sectional study the severity of OCS (Obsessive-Compulsive Inventory - Revised) and the(More)
BACKGROUND Neuropsychiatric symptoms of dementia like agitation, depression and apathy often result in increased prescriptions of psychotropics. In Germany, outpatient clinics at psychiatric hospitals play an important role in the treatment of neuropsychiatric symptoms in nursing homes. The aim of this study was to test whether the severity and(More)
