Many cases of early-onset inherited Alzheimer's disease (AD) are caused by mutations in the presenilin-1 (PS1) gene. Expression of PS1 mutations in cell culture systems and in primary neurons from transgenic mice increases their vulnerability to cell death. Interestingly, enhanced vulnerability to cell death has also been demonstrated for peripheral(More)
Violent offenders with schizophrenia have a particularly poor performance level in facial affect recognition. Nineteen male schizophrenia patients, who had been committed to psychiatric hospital detention because of violent offences and lack of criminal responsibility, were recruited to receive the Training of Affect Recognition (TAR). Performance in the(More)
Frontotemporal dementia (FTD) is a clinically and genetically heterogeneous disorder. Rare TREM2 variants have been recently identified in families affected by FTD-like phenotype. However, genetic studies of the role of rare TREM2 variants in FTD have generated conflicting results possibly because of difficulties on diagnostic accuracy. The aim of the(More)
White matter (WM) magnetic resonance imaging (MRI) hyperintensities are common in Alzheimer’s disease (AD), but their pathophysiological relevance and relationship to genetic factors are unclear. In the present study, we investigated potential apolipoprotein E (APOE)-dependent effects on the extent and cognitive impact of WM hyperintensities in patients(More)
Alzheimer's disease (AD) is a fast growing world-wide epidemic. AD is a genetically complex, slowly progressive, and irreversible neurodegenerative disease of the brain. During decades of asymptomatic progression multiple interactive systems, pathways and molecular mechanisms (e.g. protein processing, aberrant signaling, inflammation and immune system,(More)
BACKGROUND AND AIMS There is some disagreement between clinical and basic science as to the benefit of estrogen in preventing cognitive decline. For cardiovascular disease, estrogen effects have been shown to vary with estrogen receptor (ESR) genotype. The present study was conceived to review evidence of ESR association with Alzheimer's disease (AD) which(More)
Schizophrenia is a chronic illness of heterogenous biological origin. We hypothesized that, similar to chronic progressive brain conditions, persistent functional disturbances of neurons would result in disturbed proteostasis in the brains of schizophrenia patients, leading to increased abundance of specific misfolded, insoluble proteins. Identification of(More)
BACKGROUND The recently proposed latent variable δ is a new tool for dementia case finding. It is built in a structural equation modeling framework of cognitive and functional data and constitutes a novel endophenotype for Alzheimer's disease (AD) research and clinical trials. OBJECTIVE To investigate the association of δ with AD biomarkers and to compare(More)
The elevation of creatine kinase (CK) levels without neuroleptic malignant syndrome has been reported for several antipsychotics. We present here 4 cases with CK elevation induced by amisulpride, which have been registered for the German pharmacovigilance project, Arzneimittelsicherheit in der Psychiatrie (AMSP). The magnitude of the CK elevation ranged(More)
