In this pilot study, we aimed to examine whether iPad-assisted cognitive training could be beneficial in ameliorating some of the cognitive impairment that accompany schizophrenia. Totally, 20 first-episode schizophrenia patients were randomly assigned to an experiment group (with cognitive training) or to a control group (without cognitive training). The(More)
Cognitive impairment is one of the core symptoms in schizophrenia, which reflects the neurodevelopmental deficits in the etiology of this disease. Brain-derived neurotrophic factor (BDNF) plays an important role in various neurodevelopmental processes. Growing evidence has shown that BDNF may be involved in the etiology of schizophrenia. The aim of this(More)
The leucine-rich repeat kinase-2 (LRRK2) gene has been regarded as 1 of the most common genetic causes of Parkinson's disease (PD). We hypothesized that LRRK2-susceptible allele(s) for PD might pose a risk for Alzheimer's disease (AD). In this study, we screened 12 LRRK2 gene variants in 2 independent cohorts from southwestern China (341 AD patients and 435(More)
Clinical observations indicate that atypical antipsychotics, especially clozapine, induce obsessive–compulsive (OC) symptoms in schizophrenia patients. Recent data from neuroimaging and clinical trials suggest a role for altered glutamate neurotransmission in the etiology of OC disorder (OCD), and SLC1A1, GRIN2B, and GRIK2 have all been reported to regulate(More)
In this study, we examined whether common variants in the G protein-coupled receptor kinase 6 gene (GRK6) confers susceptibility to schizophrenia in Chinese. We genotyped two common variants in 697 schizophrenia patients and 563 healthy control subjects. No significant difference in either allele or genotype comparisons between the case and control groups(More)
Mitochondrial dysfunction has been widely reported in psychiatric and neurodegenerative diseases. We aimed to investigate the association between matrilineal structures of Han Chinese populations and Alzheimer's disease (AD) by a 2-stage case-control study: A total of 341 AD patients and 435 normal individuals from Southwest China were analyzed for(More)
Neuropsychological endophenotype approach is an emerging strategy in schizophrenia research to understand and identify the functional importance of genetically transmitted, brain-based deficits present in this disorder. Accumulating evidence indicated that working memory deficit is a core neuropsychological dysfunction in schizophrenia and a primary(More)
Serotonergic system-related genes may be good candidates in investigating the genetic basis of schizophrenia. Our previous study suggested that promoter region of tryptophan hydroxylase 2 gene (TPH2) may confer the susceptibility to paranoid schizophrenia. In this study, we investigated whether common variants within TPH2 promoter may predispose to paranoid(More)
With the recent attention to the importance of evidence-based medicine in psychiatry, a number of treatment guidelines have been published. This survey investigated prescribing pattern and predictors for guideline disconcordance in the acute treatment of bipolar depression across mainland China. Pharmacological treatments of 1078 patients with bipolar(More)
Mitochondrial dysfunction was widely reported in schizophrenia patients in recent studies. Leucine-rich repeat kinase 2 (LRRK2) is a mitochondrial protein, and mutations in the LRRK2 gene can induce mitochondrial dysfunction. LRRK2 mutations have been reported to be the most frequent genetic cause of Parkinson's disease (PD). We were interested in whether(More)
