Less cognitive and neurological deficits in schizophrenia patients carrying risk variant in ZNF804A Vrije Universiteit Brussel University of Antwerp
BACKGROUND: The rs1344706 single nucleotide polymorphism in the ZNF804A gene is a common variant with strong evidence for association with schizophrenia. Recent studies show an association of rs1344706 with cognitive functioning, and there is some evidence suggesting that the risk allele may increase susceptibility for a subtype of schizophrenia with relatively spared cognition.
METHODS: We tested the effect of rs1344706 genotype in 89 ...
Quantitative psychomotor dysfunction in schizophrenia Vrije Universiteit Brussel University of Antwerp
AIMS: The aim of the present study was to investigate the predictive value of qualitative psychomotor performance levels and subaspects of the negative syndrome for quantitative motor activity levels in patients with schizophrenia.
METHODS: Twenty-seven stabilized patients with schizophrenia and 22 age- and sex-matched healthy controls were included in the study. An extensive battery of psychomotor performance tests (Finger Tapping ...
The nature of the relationship of psychomotor slowing with negative symptomatology in schizophrenia Vrije Universiteit Brussel University of Antwerp
INTRODUCTION: Psychomotor slowing is an important feature of schizophrenia and the relation with negative symptoms is not fully understood. This study aims, first, to investigate the association between negative symptoms and psychomotor slowing. Second, we want to investigate whether fine motor slowing reflects clinically observable gross motor slowing.
METHODS: In 53 stabilised adult patients with schizophrenia, negative symptoms were ...
White matter microstructure and volitional motor activity in schizophrenia Vrije Universiteit Brussel University of Antwerp KU Leuven
Avolition is a core feature of schizophrenia and may arise from altered brain connectivity. Here we used diffusion kurtosis imaging (DKI) to investigate the association between white matter (WM) microstructure and volitional motor activity. Multi-shell diffusion MRI and 24-h actigraphy data were obtained from 20 right-handed patients with schizophrenia and 16 right-handed age and gender matched healthy controls. We examined correlations ...
