Objectives: Studies of the prevalence and risk factors for behavioral and psychological symptoms of dementia (BPSD) have primarily been conducted in nursing home and clinic populations. Few population-based studies have been conducted in community-living persons with dementia. Methods: In this cross-sectional study, persons aged 65 and above who were living in the community were screened for dementia with the Chinese version of Mini-Mental State Examination (CMMSE) and Ability of Daily Living (ADL-14) scale. Participants with a diagnosis of dementia according to DSM-IV criteria made by trained neuropsychiatrists s were with the Neuropsychiatric Inventory assessed for BPSD by informant interview. Results: Among 1271 persons with dementia, 50.1% had at least one BPSD. Sleep disturbance was the most common symptom (21.9%), followed by irritability (19.6%), and apathy (15.7%). About 40% (N = 501) of these problems were clinically significant (NPI score > 4). The NPI score was significantly associated with the CMMSE score, ADL score and education. Conclusion: BPSD are common among community living Chinese people with dementia, but the relatively lower prevalence rate and different pattern of symptoms from those reported in the USA, UK and Japan suggest the possible influence of cultural background and psychosocial environment. © 2013 Copyright Taylor & Francis.

Schizophrenia (SCZ) and major depressive disorder (MDD) are two of the most common and severe mental disorders, the etiologies of which are not yet clearly elucidated. The ACSM1 gene has been identified as a susceptibility gene for SCZ in two previous genome-wide association studies (GWAS). ACSM1 catalyzes the activation of fatty acids and plays an important role in the metabolic system. Some evidence has suggested that ACSM1 contributes to a genetic risk for MDD. The present study aimed to evaluate the common genetic risk of the ACSM1 gene in these two disorders in the Han Chinese population. In total, 1235 patients with SCZ, 1045 patients with MDD and 1235 control subjects of Chinese origin were recruited. Six single nuclear polymorphisms (SNPs) in ACSM1 were genotyped to test their associations with SCZ and MDD. SNP rs163234 was found to be significantly associated with both SCZ (permutated Pallele=1.700×10-3, OR=1.350 [95% CI=1.152-1.581]) and MDD (permutated Pallele=4.800×10-3, OR=1.329 [95% CI=1.127-1.567]). SNP rs433598 showed a strong association with SCZ (permutated Pallele=4.300×10-3, OR=1.303 [95% CI=1.117-1.520]). Haplotype analysis of the blocks containing the two positive markers also revealed a significant association. This is the first study to assess the possible association of the ACSM1 gene with a genetic susceptibility for MDD. Our data are the first to suggest a positive association of the ACSM1 gene with a genetic susceptibility for SCZ and MDD in the Han Chinese population. © 2015 Wiley Periodicals, Inc.

Population stratification is a problem in genetic association studies because it is likely to highlight loci that underlie the population structure rather than disease-related loci. At present, principal component analysis (PCA) has been proven to be an effective way to correct for population stratification. However, the conventional PCA algorithm is time-consuming when dealing with large datasets. We developed a Graphic processing unit (GPU)-based PCA software named SHEsisPCA (http://analysis.bio-x.cn/SHEsisMain.htm) that is highly parallel with a highest speedup greater than 100 compared with its CPU version. A cluster algorithm based on X-means was also implemented as a way to detect population subgroups and to obtain matched cases and controls in order to reduce the genomic inflation and increase the power. A study of both simulated and real datasets showed that SHEsisPCA ran at an extremely high speed while the accuracy was hardly reduced. Therefore, SHEsisPCA can help correct for population stratification much more efficiently than the conventional CPU-based algorithms. © 2015 Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, and Genetics Society of China. ©2015, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, and Genetics Society of China.

Objective: To assess the knowledge of and attitudes towards dementia among Shanghai residents. Methods: A 10-item optional questionnaire relating to dementia was developed for the project. Questionnaires were randomly distributed to 1806 families, each family had one respondent. Results: A total of 1531 questionnaires were available. Among them, 45% considered 'dementia is a normal part of ageing' and 29-41% correctly identified the symptoms of mild dementia. Of the respondents, 43% indicated that they would not be ashamed of having a demented relative, and 45% did not think that medical care benefited those with dementia. Subgroups analyses showed there was a wider agreement on the concept 'dementia is a normal part of ageing' in the elderly or the females with primary school education background than the counterpart. According to the educational level, the sequence (from the highest to the lowest) of the proportion of respondents who considered a demented relative to be shameful was as follows: middle school group (60.5%) > primary school group (41.3%) > university group (25.2%); according to age group: adult group (59.8%) > elderly group (37.3%) > youth group (30.2%). There was a higher identification rate of the symptoms of mild dementia in women than in men (P < 0.01). According to the educational level, the sequence (from the highest to the lowest) of identification rate was: university group > primary school group > middle school group; according to age group: elderly group > youth group > adult group. There was a significant difference among groups (P < 0.01). Multivariate regression results suggested that the sex, educational level and age had an influence on the concept of 'dementia is part of normal ageing'; the feeling of shame of having demented relatives was influenced by the educational level and age. Conclusion: Lack of correct knowledge about dementia and discrimination of dementia are highly prevalent among urban residents in Shanghai. © 2011 The Authors; Psychogeriatrics © 2011 Japanese Psychogeriatric Society.

Background: The aim of this study was to determine whether dysfunctional beliefs might predict treatment-resistance and to examine the relationship between fractional anisotropy (FA) in difusion tensor imaging (DTI) and cognitive biases for optimal treatment choice.Material/Methods:We recruited 11 non-resistant obsessive-compulsive disorder (OCD) patients, 11 resistant OCD patients, and 11 healthy subjects.Results: OCD patients had higher Obsessive Beliefs Questionnaire (OBQ-87) subscale scores than subjects in non-resistant and resistant groups. A signifcant diference was found between non-resistant and resistant OCD patients in R-Scale and I-Scale. A signifcant decrease in FA was found in left dorsal frontal gyrus and left inferior parietal lobule in the non-resistant group as compared to the control group. FA also decreased signifcantly in left anterior cingulate cortex, putamen, and nucleus accumbens in the resistant group as compared to the control group. There was a signifcant decrease in FA in nucleus accumbens in the resistant group as compared to the non-resistant group. Reduced FA in left nucleus accumbens was negatively associated with OBQ-87 factor R and I and the total Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).Conclusions: Abnormalities in cortical-striatal white matter networks may contribute to the dysfunctional beliefs in patients with treatment-resistant OCD, and the left nucleus accumbens may be an important and promising target for the treatment of OCD. © Med Sci Monit, 2014.

Schizophrenia (SCZ) is a common and severe mental disorder, its etiology has not been elucidated completely. In one previous genome-wide association study (GWAS) of SCZ in the Caucasian population, the QPCT has been reported as susceptible gene for SCZ. The QPCT gene encodes Glutaminyl cyclase (QC), an enzyme which is involved in the post translational modification by converting N-terminal glutamate of protein to pyroglutamate, which is resistant to protease degradation, more hydrophobic, and prone to aggregation and neurotoxic. To further investigate the role of this gene in the pathogenesis of schizophrenia in the Han Chinese population, we conducted this study in 1,248 (Mean ageS.D, 36.44 years9.0) SCZ cases, 1,248 (Mean ageS.D, 30.62 years11.35) healthy control samples for a case control study. We genotyped six SNPs in this study, including one positive SNP of the previous study, using the Sequenom MassARRAY platform. We found that rs2373000 was significantly associated with SCZ before correction [rs2373000: P allele=0.016, (2) =5.784, OR [95%CI]=0.861 [0.762-0.972], P genotype=0.018, (2) =0.069]. After permutation correction for multiple testing, rs2373000 [rs2373000: P Allele corrected=0.063, P genotype corrected=0.069] showed marginal association with SCZ. Additionally, one pathogenic haplotype (TGT) containing rs2373000 was also significantly associated with SCZ. Our results are consistent with the findings of previous study and the genetic risk of QPCT gene for SCZ also exists in the Han Chinese population.
