Li WC, Chao HT, Lin MW, Shen HD, Chen LF, Hsieh JC. Neuroprotective effect of Val variant of BDNF Val66Met polymorphism on hippocampus is modulated by the severity of menstrual pain. NEUROIMAGE-CLINICAL 2021; 30:102576. [PMID: 33561695 PMCID: PMC7873439 DOI: 10.1016/j.nicl.2021.102576] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 01/10/2021] [Accepted: 01/15/2021] [Indexed: 12/19/2022]
Abstract
Primary dysmenorrhea (PDM) refers to menstrual pain of which the pathological cause(s) are unknown. This study examined the associations among BDNF Val66Met polymorphisms, menstrual pain severity, and hippocampal volume among young PDM subjects. We recruited 115 PDM subjects, including severe cases (n = 66) and moderate cases (n = 44), and 117 young females (aged 20-30 years) as a control group (CON) for BDNF Val66Met genotyping and MRI examination. The assessment of hippocampal volume involved analysis at various anatomical resolutions, i.e., whole hippocampal volume, hippocampal subfields, and voxel-based morphometry (VBM) volumetric analysis. Two-way ANOVA analyses with planned contrasts and Bonferroni correction were conducted for the assessment of hippocampal volume. Linear regression was used to test for BDNF Val66Met Val allele dosage-dependent effects. We observed no main effects of group, genotype, or group-genotype interactions on bilateral whole hippocampal volumes. Significant interactions between PDM severity and BDNF Val66Met genotype were observed in the right whole hippocampus, subiculum, and molecular layer. Post-hoc analysis revealed that the average hippocampal volume of Val/Val moderate PDM subjects was greater than that of Val/Val severe PDM subjects. Note that right hippocampal volume was greater in the Val/Val group than in the Met/Met group, particularly in the right posterior hippocampal region. Dosage effect analysis revealed a positive dosage-dependent relationship between the Val allele and volume of the right whole hippocampus, subiculum, molecular layer, and VBM-defined right posterior hippocampal region in the moderate PDM subgroup only. These findings indicate that Val/Val PDM subjects are resistant to intermittent moderate pain-related stress, whereas Met carrier PDM subjects are susceptible. When confronted with years of repeated PDM stress, the hippocampus can undergo differential structural changes in accordance with the BDNF genotype and pain severity. This triad study on PDM (i.e., combining genotype with endophenotype imaging results and clinical phenotypes), underscores the potential neurobiological consequences of PDM, which may prefigure in neuroimaging abnormalities associated with various chronic pain disorders. Our results provide evidence for Val allele dosage-dependent protective effects on the hippocampal structure; however, in cases of the Val variant, these effects were modulated in accordance with the severity of menstrual pain.

Abstract
OBJECTIVE This study aimed to investigate the risk of dementia among subgroups of patients receiving concurrent antidepressant and hypnotic treatment, antidepressants alone, and hypnotics alone. METHODS Multivariate Cox proportional hazards regression models were used to determine the effects of antidepressants and hypnotics on dementia risk after adjusting for potential confounders. RESULTS Compared with the reference group, patients receiving concurrent antidepressant and hypnotic treatment had the highest adjusted hazard ratio (aHR: 2.390, 95% CI: 2.224-2.536; P < 0.001) for all-cause dementia, followed by those receiving antidepressants alone (aHR: 1.919, 95% CI: 1.811-2.012; P < 0.001) and hypnotics alone (aHR: 1.458, 95% CI: 1.397-1.527; P < 0.001). With regard to dementia subtypes, trends similar to those for all-cause dementia were observed for Alzheimer's dementia, vascular dementia and other types of dementia. The sensitivity analysis conducted also found the robustness of findings. Notably, inconsistent findings were observed in subgroup with depression, revealing a null association between concurrent antidepressant and hypnotic treatment (aHR: 0.496; 95% CI: 0.183-1.343; P = 0.175) or hypnotics alone (aHR: 2.750; 95% CI: 0.797-9.482; P = 0.102) and the risk of dementia, and a negative association between antidepressants alone (aHR: 0.351; 95% CI: 0.130-0.942; P = 0.032) and the risk of dementia. CONCLUSION A null or negative association was observed between concurrent antidepressant and hypnotic treatment, antidepressants alone, hypnotics alone, and the dementia risk in the subgroup of patients with depression, suggesting the absence of an association between dementia risk and antidepressants alone or hypnotics alone.

Abstract
Background Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, caused by NOTCH3 mutations, is characterized by recurrent ischemic strokes and progressive cognitive decline. It remains unclear whether cerebral microbleeds (CMBs) can serve as a surrogate marker for disease progression in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. We aimed to investigate the CMB burdens in NOTCH3 mutation carriers at different disease stages and test their associations with cognitive performance. Methods and Results Forty‐nine individuals carrying NOTCH3 cysteine‐altering mutations received brain magnetic resonance imaging with T1‐weighted and susceptibility‐weighted images. Whole brain images were segmented into 14 regions using Statistical Parametric Mapping and FreeSurfer software, and semiautomatic methods were used to locate and quantify the number and volume of CMBs. In our study participants, the median of CMB counts was 13, with a wide individual variation (range, 0–286). CMBs were most frequently present in thalamus, followed by temporal lobe. In the whole brain, the CMB counts and CMB volume ratios (ie, CMB volume divided by the volume of corresponding brain region) gradually increased as the disease advanced. CMB counts in the thalamus and temporal and frontal lobes increased more rapidly than other brain regions as disease progressed. There were significant associations between Mini‐Mental State Examination scores and CMB counts in the frontal lobe, temporal lobe, and pons. Conclusions CMBs may have an influential role in the clinical manifestations of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. CMB burdens and their distribution in different brain regions may be capable to serve as a disease marker for monitoring the disease severity of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

Abstract
Objective: To investigate the clinical characteristics, treatment and prognosis of myelin oligodendrocyte glycoprotein antibody-associated optic neuritis (MOG-ON) in pediatric patients. Methods: Clinical data, laboratory examination, the initial best corrected visual acuity (BCVA), fundus, neuroelectrophysiological results, MRI imaging, treatment and prognosis of children diagnosed with MOG-ON from 2016 to 2019 were retrospectively analyzed. Results: A total of 29 eyes from 16 children were involved, with a male/female ratio of 1∶1, onset age of (7.0±2.9) years. Seven of 16 patients had prodromal infection, with a unilateral/bilateral ratio of 3∶13, and 2 cases had recurrent optic neuritis. Before treatment, BCVA of 19 eyes (65.5%) was ≤0.1, among them, 4 had no sense of light, 5 had light sense, 5 with sense of hands in front of eyes, and 5 with sense of fingers in front of eyes. There were 10 eyes (34.5%) with BCVA of 0.1-0.5. After treatment, there were 4 eyes (13.8%), 5 eyes (17.2%) and 20 eyes (69.0%) in groups with BCVA of 0.1-0.5, 0.5-1.0, and>1.0, respectively. Twelve of 16 patients had optic papillitis in fundus examination during acute phase. The latency was prolonged and the amplitude was decreased in P100 wave of all the children. Thirteen out of 16 children showed swelling and thickening of optic nerve in MRI T2WI. MRI images exhibited intracranial demyelinating lesions in 12 of 16 children and long segment spinal cord lesions in 3 of 16 children. Thirteen of 16 patients showed effective results after intravenous methylprednisolone (IVMP) and intravenous immunoglobulin (IVIG) treatment. There was no relapse after administration of mycophenolate mofetil in 2 recurrent children. No progression after administration of rituximab was found in 1 child with corticosteroid insensitivity. The average follow-up time was (16±9) months and no recurrence occurred. Ten of 16 patients had full recovery, 4 had significant improvement, and 2 showed no significant improvement. Conclusions: There is no significant gender difference in the incidence of pediatric MOG-ON. Bilateral involvement and severe visual impairment are common in acute phase. Most patients have good response to IVMP combined with IVIG treatment and hence have a good prognosis. Only a few of them have neurological sequelae.

Abstract
The risk of pain after electroconvulsive therapy (ECT) among depressed patients is still controversial. We aimed to investigate the risk of pain post-ECT among patients with depression. We investigated patients with depression, based on the data in the National Health Insurance Research Database. A comparison cohort comprising depressed non-ECT patients with at least three psychiatric admissions were matched. A Cox proportional regression model was used to investigate the risk of pain between the ECT and comparison cohorts. The ECT and comparison cohorts consisted of 1246 and 4984 patients, respectively. Compared to the control group patients, the ECT group patients had a significantly increased risk of developing overall pain (aHR = 5.753; 95% CI: 2.405-11.760; P < 0.001). Specifically, the risk of developing headache (aHR = 7.270; 95% CI: 1.226-47.731; P = 0.026) and musculoskeletal pain (MSP; aHR = 5.330; 95% CI: 2.937-11.663; P = 0.001) was significantly higher than in the control group. The sensitivity analysis, which involved checking pain events for each week to the end of the study, also provided significant findings in overall pain (aHR = 13.013, 95% CI: 2.121-94.258, P < 0.001), headache (aHR = 10.995; 95% CI: 1.099-122.601; P = 0.042) and MSP (aHR = 14.210, 95% CI: 2.436-82.898, P = 0.003) within 3 weeks of follow-up. This study suggests that depressed patients who undergo ECT may have an increased risk of developing subsequent pain. Further research is warranted to elucidate whether pain is associated with ECT because several potential confounders existed.

Abstract
Objective: To analyze the clinical features, outcome and prognosis of pediatric myelin oligodendrocyte glycoprotein (MOG) antibody associated acute disseminated encephalomyelitis (ADEM), and provide evidence for improving the diagnosis and treatment of this disease. Methods: This study involved 30 MOG antibody-associated ADEM patients in the Department of Neurology, Guangzhou Women and Children's Medical Center. Patients' clinical information were analyzed. Results: The mean onset age was (5.2±3.3) years old, the ration of male to female was 16∶14. Fifty percent of these patients had a history of precede infection or vaccination before onset. Encephalopathy and seizures were the most common clinical manifestations, followed by movement disorder. In addition, some patients had other positive autoantibodies. Brain Magnetic resonance imaging (MRI) showed extensive, asymmetrical, indefinite large patchy lesions in bilateral cortical and subcortical areas and the spinal cord was characterized by long segmental myelitis. In acute attack, the patients had a good response to corticosteroid combined immunoglobulin therapy. Most of these patients had a good prognosis and recurrence rate was about 20%. Conclusions: The onset age of MOG antibody-associated ADEM is around 5 years old. Encephalopathy and seizures were the most common clinical manifestations. Most patients have a good response to corticosteroid combined immunoglobulin therapy. Some patients may have a recurrent disease course.

Abstract
Objective: To explore the value of dual-energy CT-based volumetric iodine-uptake (VIU) in the evaluation of chemotherapy efficacy in advanced gastric cancer. Methods: Inclusion criteria of subjects: (1) without previous systematic therapy; (2) with complete clinical information before and after chemotherapy; (3) without contraindications of chemotherapy. Exclusion criteria of subjects: (1) unfinished duration and times of chemotherapy; (2) unmeasurable primary lesions; (3) poor imaging quality or poor gastric filling. Clinical and image data of 52 patients with advanced gastric cancer who were diagnosed by pathology from gastroscopic biopsy, and needed chemotherapy evaluated by imaging and clinical information in the First Affiliated Hospital of Wenzhou Medical University from February 2017 to February 2018 were collected and analyzed. Of 52 patients, 38 were male and 14 were female with the median age of 65 (31-88) years old. All the patients underwent a dual-energy, dual phase-enhanced CT scanning before chemotherapy and after the third chemotherapy session. The parameters of the lesions measured before and after chemotherapy in portal vein phase were as follows: the maximum diameter (the largest diameter among those measured in the cross-sectional, coronal, and sagittal planes), average CT value (the regions of interest were manually pinpointed under cross-sectional planes with largest diameter of the tumor, which did not include regions less than 2 mm to the edge of the tumor) and VIU (lesion volume × iodine concentration). The change rates of maximum lesion diameter, average CT value and VIU before and after chemotherapy were calculated [(post-chemotherapy parameters-pre-chemotherapy parameters)/ pre-chemotherapy parameters]. The efficacy of chemotherapy was evaluated by RECIST 1.1 (the change of maximum tumor diameter after chemotherapy), Choi (the change of average CT value after chemotherapy) and VIU (the change of VIU after chemotherapy), respectively, which was categorized by complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). Patients with CR, PR, and SD were assigned to the effective group, while those with PD were classified as the ineffective group. Paired t - test or Wilcoxon signed ranks test was used to compare the changes of parameters before and after chemotherapy, whereas Spearman correlation analysis and Kappa test were used for the correlation analysis and the consistency test between the three evaluation criteria (Kappa≥0.75 indicated good consistency). Results: After chemotherapy, the average CT value [(74.01±16.75) HU vs. (81.06±15.87) HU, t=2.202, P=0.030] and median VIU (668.53×10(2) μg vs. 272.52×10(2) μg, Z=4.761, P<0.001) decreased significantly, while the difference of the maximum diameter was not statistically significant [(66.71±34.49) mm vs. (78.45±35.62) mm, t=1.708, P=0.091]. The median change rate of VIU (-53.33%) was greater than that of CT values (-5.75%) with significant difference (Z=-5.408, P<0.001). According to the RECIST 1.1 criteria, 47 patients (90.4%, including 19 with PR and 28 with SD) were effective and 5 patients (9.6%) were ineffective. According to the Choi criteria, 45 patients (86.5%, including 37 with PR and 8 with SD) were effective and 7 patients (13.5%) were ineffective. According to the VIU criteria, 46 patients (88.5%, including 41 with PR and 5 with SD) were effective and 6 patients (11.5%) were ineffective. Efficacy comparison among these three criteria showed no significant difference (χ(2)=0.377, P=0.828). As compared to RECIST 1.1 evaluation, the proportion of PR evaluated by Choi and VIU was significantly higher (χ(2)=16.861, P<0.001), whereas the proportion of SD was significantly lower (χ(2)=24.089, P<0.001). There was no significant difference in the proportions of PR and SD between VIU and Choi criteria (χ(2)=0.887, P=0.346). Consistency and correlation analysis showed that the VIU and Choi evaluation criteria presented the highest consistency and correlation (Kappa=0.912, P<0.001; r=0.916, P<0.001). Conclusion: VIU is a feasible parameter for the evaluation of chemotherapy efficacy in advanced gastric cancer, and may be more sensitive than the evaluation criteria based on maximum diameter or change of CT value in the tumor.

Abstract
STUDY OBJECTIVES The association between posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) has been reported inconsistently, and the association between antidepressant use and the risk of developing OSA in patients with PTSD has not been previously studied. Therefore, we used the Longitudinal National Health Insurance Database (LHID) to investigate the impact of PTSD and antidepressant use on the risk of OSA development. METHODS Identified from the LHID, 2,316 individuals aged ≥ 18 years with PTSD, but with no history of OSA, and 23,160 control individuals matched for age, sex, obesity and index date were enrolled between 2000 and 2015 and followed up until the end of 2015 to identify the development of OSA. A two-tailed Bonferroni-corrected P < .00038 (.05/13) was considered statistically significant as we examined 13 antidepressants. RESULTS Individuals with PTSD had increased risk of developing OSA (adjusted hazard ratio 4.672, 95% confidence interval 2.246-9.787, P < .001) after adjusting for demographic data, medical comorbidities, and medication. Treatment with antidepressants was not significantly associated with an increased risk of developing OSA compared to no antidepressant treatment. CONCLUSIONS Asian patients with PTSD had increased risk of developing OSA, and treatment with antidepressants did not play a key role in increasing the risk of OSA development. Further studies are required to investigate the underlying mechanisms of PTSD and the roles of antidepressants on the risk of developing OSA.

Abstract
OBJECTIVE The aim of this study was to analyze the risk of inpatient suicide in patients with schizophrenia during 2007-2013 and to determine putative risk factors. METHODS We conducted a national population-based cohort study of 2,038 psychiatric inpatients in their first compulsory admission, matched with 8,152 controls who were voluntary inpatients. Only patients with schizophrenia were included in the study. We used data derived from the Taiwanese National Health Insurance Database 2005, comprising 1 million beneficiaries randomly selected from the entire population of Taiwan. RESULTS During the follow-up period, 23 and 75 inpatient suicides were observed in the compulsory and control groups, respectively. Kaplan-Meier curves showed that the cumulative incidence rate of inpatient suicide was not significantly different between compulsory and voluntary admissions (log-rank test, p = .206). CONCLUSIONS Our results suggest that compulsory admission has no protective effects on risk reduction of inpatient suicide for patients with schizophrenia who are compulsorily admitted compared with voluntarily admitted controls. Clinicians should be more alert for the prevention of inpatient suicide among patients with schizophrenia and consider the close monitoring of inpatient suicide risk in the first week of admission.

Abstract
Objective: To reduce the occurrence of adverse events of clinical blood use by analyzing the clinical adverse events of blood use except for the adverse reactions of blood transfusion. Methods: A retrospective analysis was performed on 294 cases of adverse events of clinical blood use other than adverse blood transfusion reactions in Shijitan hospital from January 2014 to December 2017, and a statistical analysis was made on the types of adverse events of clinical blood use, blood transfusion related departments, and internal and surgical blood use. Results: The incidence of adverse events of clinical blood use was 10.3‰, 9.6‰, 4.2‰ and 4.6‰ in these 4 years respectively, and there were 216 cases (73.5%) of external departments, 49 cases (16.7%) of internal departments, 8 cases (2.7%) of nursing departments, and 21 cases of others(7.1%), which includes 12 cases of errand department, 4 cases of the clinical laboratory and 5 cases of transfusion department. The adverse events of clinical blood use were divided into 4 types: 71 cases (24.1%) of transfusion process problems, 36 cases (12.2%) of clinical communication between departments, 182 cases (61.9%) of clinical unreasonable transfusion and 5 others (1.8%). There were statistically significant differences in the occurrence of adverse events of different types of blood use in external and internal departments based on the property of the department, among which there were significant differences in unreasonable transfusion between them. According to the purpose of blood use, there were statistically significant differences in the occurrence of different types of adverse events between the two departments, and the incidence of different types of external departments were higher than that of internal departments. Conclusions: The incidence of adverse events of blood use in external departments is higher than that in internal departments. Reasonable transfusion should be strengthened to avoid the occurrence of adverse events of clinical blood use, so as to ensure the safety of blood transfusion.

Abstract
PURPOSE The aim of this study was to assess the risk of psychiatric readmission in patients with schizophrenia, compare it between patients prescribed compulsory admission and those consenting to voluntary admission, and determine risk factors for psychiatric readmission. METHODS This 7-year (2007-2013), population-based, cohort study retrospectively compared data of 2038 schizophrenic inpatients who initially underwent compulsory admission (the CA group) and of 8152 matched controls with schizophrenia who initially underwent voluntary admission (the VA group). RESULTS During the study period, there were 1204 and 3806 readmissions in the CA and VA groups, respectively. Compared with the VA group, the CA group was associated with a greater risk of psychiatric readmission [adjusted hazard ratio (AHR) = 1.765; 95% confidence interval (CI) 1.389-2.243; P < 0.001]. Stratified analyses showed that the CA group was associated with a higher risk of subsequent compulsory (AHR = 1.307; 95% CI 1.029-1.661; P < 0.001) and voluntary (AHR = 1.801; 95% CI 1.417-2.289; P < 0.001) readmissions compared to the VA group. Sensitivity analyses, after excluding data from the first year of observation, also provided significant findings with respect to compulsory and voluntary readmissions. Kaplan-Meier curves revealed that cumulative survival rates of psychiatric readmissions, compulsory and voluntary readmissions were significantly lower in the CA group than in the VA group among patients with schizophrenia (log-rank test, P < 0.001). CONCLUSIONS CA was associated with higher subsequent psychiatric readmissions, compulsory, and voluntary readmissions. Clinicians would need to focus on patients undergoing CAs to reduce readmissions.

Abstract
The irregularity and uncertainty of neurophysiologic signals across different time scales can be regarded as neural complexity, which is related to the adaptability of the nervous system and the information processing between neurons. We recently reported general loss of brain complexity, as measured by multiscale sample entropy (MSE), at pain-related regions in females with primary dysmenorrhea (PDM). However, it is unclear whether this loss of brain complexity is associated with inter-subject genetic variations. Brain-derived neurotrophic factor (BDNF) is a widely expressed neurotrophin in the brain and is crucial to neural plasticity. The BDNF Val66Met single-nucleotide polymorphism (SNP) is associated with mood, stress, and pain conditions. Therefore, we aimed to examine the interactions of BDNF Val66Met polymorphism and long-term menstrual pain experience on brain complexity. We genotyped BDNF Val66Met SNP in 80 PDM females (20 Val/Val, 31 Val/Met, 29 Met/Met) and 76 healthy female controls (25 Val/Val, 36 Val/Met, 15 Met/Met). MSE analysis was applied to neural source activity estimated from resting-state magnetoencephalography (MEG) signals during pain-free state. We found that brain complexity alterations were associated with the interactions of BDNF Val66Met polymorphism and menstrual pain experience. In healthy female controls, Met carriers (Val/Met and Met/Met) demonstrated lower brain complexity than Val/Val homozygotes in extensive brain regions, suggesting a possible protective role of Val/Val homozygosity in brain complexity. However, after experiencing long-term menstrual pain, the complexity differences between different genotypes in healthy controls were greatly diminished in PDM females, especially in the limbic system, including the hippocampus and amygdala. Our results suggest that pain experience preponderantly affects the effect of BDNF Val66Met polymorphism on brain complexity. The results of the present study also highlight the potential utilization of resting-state brain complexity for the development of new therapeutic strategies in patients with chronic pain.

Abstract
Primary dysmenorrhea (PDM), painful menstruation without organic causes, is the most prevalent gynecological problem in women of reproductive age. Dysmenorrhea later in life often co-occurs with many chronic functional pain disorders, and chronic functional pain disorders exhibit altered large-scale connectedness between distributed brain regions. It is unknown whether the young PDM females exhibit alterations in the global and local connectivity properties of brain functional networks. Fifty-seven otherwise healthy young PDM females and 62 age- and education-matched control females participated in the present resting-state functional magnetic resonance imaging study. We used graph theoretical network analysis to investigate the global and regional network metrics and modular structure of the resting-state brain functional networks in young PDM females. The functional network was constructed by the interregional functional connectivity among parcellated brain regions. The global and regional network metrics and modular structure of the resting-state brain functional networks were not altered in young PDM females at our detection threshold (medium to large effect size differences [Cohen's d ≥ 0.52]). It is plausible that the absence of significant changes in the intrinsic functional brain architecture allows young PDM females to maintain normal psychosocial outcomes during the pain-free follicular phase.

Abstract
AbstractBackground:The extent to which schizophrenia is associated with the risk of all-cause dementia is controversial. This study investigated the risk of dementia by type in patients with schizophrenia.Methods:Data were collected from the Taiwanese National Health Insurance Database 2005 and analyzed using multivariate Cox proportional hazard regression models to determine the effect of schizophrenia on the dementia risk after adjusting for demographic characteristics, comorbidities, and medications. Fine and Gray's competing risk analysis was used to determine the risk of dementia, as death can act as a competing risk factor for dementia.Results:We assessed 6040 schizophrenia patients and 24,160 propensity scale-matched control patients. Schizophrenia patients exhibited a 1.80-fold risk of dementia compared to controls (adjusted hazard ratio [aHR] = 1.80, 95% confidence interval [CI] = 1.36 ∼ 2.21,p <0.001) after adjusting for covariates. Cardiovascular disease (aHR = 5.26; 95% CI = 4.50 ∼ 6.72;p <0.001), hypertension (aHR = 1.83; 95% CI = 1.77 ∼ 2.04;p= 0.002), traumatic head injury (aHR = 1.35; 95% CI = 1.24 ∼ 1.78;p <0.001), chronic lung diseases (aHR = 1.64; 95% CI = 1.13 ∼ 2.56;p <0.001), alcohol-related disorders (aHR = 3.67; 95% CI = 2.68 ∼ 4.92;p <0.001), and Parkinson’s disease (aHR = 1.72; 95% CI = 1.25 ∼ 2.40;p <0.001) were significantly associated with dementia risk. Notably, first-generation antipsychotics (aHR = 0.80; 95% CI = 0.56 ∼ 0.95;p=0.044) and second-generation antipsychotics (aHR = 0.24; 95% CI = 0.11 ∼ 0.60;p <0.001) were associated with a lower dementia risk. Sensitivity tests yielded consistent findings after excluding the first year and first 3 years of observation. Patients with schizophrenia had the highest risk of developing Alzheimer’s [dementia/disease?] among dementia subtypes (aHR = 2.10; 95% CI = 1.88 ∼ 3.86;p< 0.001), followed by vascular dementia (aHR = 1.67; 95% CI = 1.27 ∼ 2.12;p< 0.001) and unspecified dementia (aHR = 1.30; 95% CI = 1.04 ∼ 2.01;p< 0.001).Conclusions:Schizophrenia was significantly associated with the risk of all-cause dementia. Data are scarce on the mechanisms through which antipsychotic agents protect persons with schizophrenia from developing dementia. Further research is recommended to elucidate the neurobiological mechanisms underlying the association between schizophrenia and dementia, and whether antipsychotics protect against the development of dementia in schizophrenia.

Abstract
The main challenge in decoding neural representations lies in linking neural activity to representational content or abstract concepts. The transformation from a neural-based to a low-dimensional representation may hold the key to encoding perceptual processes in the human brain. In this study, we developed a novel model by which to represent two changeable features of faces: face viewpoint and gaze direction. These features are embedded in spatiotemporal brain activity derived from magnetoencephalographic data. Our decoding results demonstrate that face viewpoint and gaze direction can be represented by manifold structures constructed from brain responses in the bilateral occipital face area and right superior temporal sulcus, respectively. Our results also show that the superposition of brain activity in the manifold space reveals the viewpoints of faces as well as directions of gazes as perceived by the subject. The proposed manifold representation model provides a novel opportunity to gain further insight into the processing of information in the human brain.
