Clinico-demographic factors associated with the treatment response to cognitive behavioral therapy for insomnia. Biopsychosoc Med 2024; 18:13. [PMID: 38760779 PMCID: PMC11100051 DOI: 10.1186/s13030-024-00308-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 05/06/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND Cognitive behavioral therapy for insomnia (CBT-I) is among the recommended non-pharmacological treatments for patients with insomnia. While there are multiple reports on the effects of CBT-I treatment, few studies evaluating the factors associated with the treatment response to CBT-I have been reported. The present study aimed to confirm the effects of CBT-I in patients with insomnia and to examine the clinico-demographic factors that can predict the outcomes of CBT-I in these patients. METHODS Overall, 62 patients were included in the present study. To confirm the effectiveness of CBT-I, we compared the pre- and post-CBT-I therapy values of several sleep parameters. Furthermore, to identify the clinico-demographic factors that could be predictive of the treatment response to CBT-I, we performed generalized linear model (GLM) analysis. RESULTS The values of several sleep parameters were significantly lower after treatment than at baseline. The results of the GLM analysis revealed that sex and occupation were significantly associated with the treatment response to CBT-I. CONCLUSIONS The present results suggest that several clinico-demographic factors should be considered in the treatment of patients with insomnia.

Actual Clinical Practice Assessment: A Rapid and Easy-to-Use Tool for Evaluating Cognitive Decline Equivalent to Dementia. Cureus 2024; 16:e58781. [PMID: 38784298 PMCID: PMC11111597 DOI: 10.7759/cureus.58781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/21/2024] [Indexed: 05/25/2024] Open
Abstract
Background Screening tests reveal the early signs of cognitive decline, enabling better self-care and preparation for the future. We developed and evaluated the accuracy of a rapid (20 s) and easy-to-use tool called ONSEI, assessing the cognitive decline equivalent to dementia in actual clinical practice by correlating clinical diagnoses with the ONSEI classification. Methods In this retrospective observational study, data were collected from individuals who visited three neurosurgical clinics in neighboring prefectures of Tokyo, Japan. ONSEI analysis was performed using a smartphone or tablet. The tool adopts a machine-learning algorithm using the speaker's age, time-orientation task score, and acoustic features of spoken responses to that task. Significant differences in accuracy, sensitivity, and specificity were evaluated by Fisher's exact test. Results The overall classification accuracy of ONSEI was 98.1% (p<0.001). The sensitivity and specificity were 97.3% (p<0.001) and 98.5% (p<0.001), respectively. The proportion of correct classifications was consistent across different age groups. Conclusion ONSEI showed high classification accuracy for dementia in cognitively normal individuals in actual clinical practice, regardless of the facility at which the tests were conducted or the age of the participants. Thus, ONSEI can be useful for dementia screening and self-care.

Association between the early repolarization pattern and nocturnal suicide attempts. Neuropsychopharmacol Rep 2024. [PMID: 38494338 DOI: 10.1002/npr2.12433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2023] [Revised: 02/26/2024] [Accepted: 03/05/2024] [Indexed: 03/19/2024] Open
Abstract
AIM Numerous recent reports have highlighted the association between mental disorders and electrocardiographic findings. The early repolarization pattern (ERP) on electrocardiogram has been linked with a history of suicide attempts and attention deficit hyperactivity disorder, and associations with impulsivity have also been reported. It is known that suicidal intent is more common at night. Patients who have a mental disorder and ERP may have a higher likelihood of impulsivity, potentially increasing the risk of suicide at night. METHODS The subjects were 43 patients with a history of suicide attempts who had undergone electrocardiographic examination at Jikei University School of Medicine Kashiwa Hospital and received intervention from our department. Due to the diurnal variation in electrocardiographic findings, only patients who underwent the examination during the daytime were included. Patients' clinical backgrounds were compared according to the presence or absence of ERP, and the association between nocturnal suicide attempts and ERP was examined using multivariate analysis. RESULTS The frequency of nocturnal suicidal behavior was 76.2% in patients with ERP and 31.8% in those without ERP, but the difference was not significant after Bonferroni correction. In the multivariate analysis, there was a significant association of ERP with nocturnal suicide attempts (p = 0.018). CONCLUSION The finding of an association between ERP and nocturnal suicide attempts indicates that ERP is a biological indicator that can predict nocturnal suicide attempts.

Identification of a strong genetic risk factor for major depressive disorder in the human virome. iScience 2024; 27:109203. [PMID: 38414857 PMCID: PMC10897923 DOI: 10.1016/j.isci.2024.109203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 11/07/2023] [Accepted: 02/07/2024] [Indexed: 02/29/2024] Open
Abstract
The heritability of major depressive disorder (MDD) is reportedly 30-50%. However, the genetic basis of its heritability remains unknown. Within SITH-1, a risk factor for MDD in human herpesvirus 6B (HHV-6B), we discovered a gene polymorphism with a large odds ratio for an association with MDD. It was a sequence whose number of repeats was inversely correlated with SITH-1 expression. This number was significantly lower in MDD patients. Rates for 17 or fewer repeats of the sequence were 67.9% for MDD and 28.6% for normal controls, with an odds ratio of 5.28. For patients with 17 or less repeats, the rate for presence of another MDD patient in their families was 47.4%, whereas there were no MDD patients in the families of patients with more than 17 repeats. Since HHV-6B is transmitted primarily mother to child and within families and persists for life, this gene polymorphism could potentially influence heritability of MDD.

Abstract
BACKGROUND AND HYPOTHESIS Given the heterogeneity and possible disease progression in schizophrenia, identifying the neurobiological subtypes and progression patterns in each patient may lead to novel biomarkers. Here, we adopted data-driven machine-learning techniques to identify the progression patterns of brain morphological changes in schizophrenia and investigate the association with treatment resistance. STUDY DESIGN In this cross-sectional multicenter study, we included 177 patients with schizophrenia, characterized by treatment response or resistance, with 3D T1-weighted magnetic resonance imaging. Cortical thickness and subcortical volumes calculated by FreeSurfer were converted into z scores using 73 healthy controls data. The Subtype and Stage Inference (SuStaIn) algorithm was used for unsupervised machine-learning analysis. STUDY RESULTS SuStaIn identified 3 different subtypes: (1) subcortical volume reduction (SC) type (73 patients), in which volume reduction of subcortical structures occurs first and moderate cortical thinning follows, (2) globus pallidus hypertrophy and cortical thinning (GP-CX) type (42 patients), in which globus pallidus hypertrophy initially occurs followed by progressive cortical thinning, and (3) cortical thinning (pure CX) type (39 patients), in which thinning of the insular and lateral temporal lobe cortices primarily happens. The remaining 23 patients were assigned to baseline stage of progression (no change). SuStaIn also found 84 stages of progression, and treatment-resistant schizophrenia showed significantly more progressed stages than treatment-responsive cases (P = .001). The GP-CX type presented earlier stages than the pure CX type (P = .009). CONCLUSIONS The brain morphological progressions in schizophrenia can be classified into 3 subtypes, and treatment resistance was associated with more progressed stages, which may suggest a novel biomarker.

Characteristics of patients with anxiety disorder without selective serotonin reuptake inhibitor prescription over a two-year period of pharmacotherapy. Neuropsychopharmacol Rep 2024; 44:67-72. [PMID: 37735810 PMCID: PMC10932764 DOI: 10.1002/npr2.12379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 09/04/2023] [Accepted: 09/08/2023] [Indexed: 09/23/2023] Open
Abstract
INTRODUCTION Pharmacotherapy such as selective serotonin reuptake inhibitors (SSRIs) or serotonin-noradrenaline reuptake inhibitors is recommended for the treatment of anxiety disorders. Although there are patients with persisted symptoms of anxiety disorders who are treated with monotherapy of benzodiazepine anxiolytics without SSRIs, the characteristics of these patients are unclear. In the present study, we investigated the characteristics of patients with persisted symptoms of anxiety disorder without SSRI prescription. METHODS From a prescription dataset covering 2018 and 2020, the prescriptions of 243 patients with anxiety disorder were analyzed. Patients were classified into two groups: SSRI non-prescription and prescription groups. RESULTS The SSRI non-prescription group had a higher ratio of females than did the SSRI prescription group (60.1% vs. 44.6%, respectively, p = 3.12 × 10-2 ), but statistically not significant after the Bonferroni correction. No significant differences in age, body mass index, or duration of outpatient visits were found between groups. Among the independent variables, sex (female) was the only variable identified that predicted SSRI non-prescription. CONCLUSION The present study showed that among patients with anxiety disorders, sex (female) was the only variable that predicted SSRI non-prescription.

Abstract
AIM The objective of this study was to reveal risk factors for incident of frontotemporal dementia (FTD) compared with Alzheimer disease (AD) in Japan. METHOD Fifty consecutive subjects diagnosed with FTD according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) under 75 years old were included retrospectively. As a control group, 48 subjects who were diagnosed with AD according to the DSM-5 and matched by age, sex, educational history, and Mini-Mental State Examination were also included. In order to examine the distinctive risk factors of FTD, we compared the relationship between symptomatologic features, Clinical Dementia Rating, clinical factors, and sociopsychological factors in the two groups. RESULT Patients with FTD were more likely than patients with AD to have meticulous premorbid personality and less likely to have a history of diabetes than patients with AD. Although the regression analysis was not significant, a history of psychiatric disorders tends to affect the incidence of FTD. CONCLUSIONS These findings regarding the risk of FTD are expected to lead to early diagnosis and care of FTD. Geriatr Gerontol Int 2023; 23: 932-937.

Personality Traits Associated with Treatment Choice with an Explicit Statistical Prediction After an Explanation in a Negative Context: A Study in Patients with Glaucoma. Clin Ophthalmol 2023; 17:3685-3691. [PMID: 38058693 PMCID: PMC10697141 DOI: 10.2147/opth.s435706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 11/07/2023] [Indexed: 12/08/2023] Open
Abstract
Purpose Over 50% of patients with early-stage glaucoma discontinue topical therapy within the first 6 months of treatment initiation. This risk of discontinuation could be reduced by how the ophthalmologist explains the treatment plan. Ophthalmologists can explain the treatment plan to patients in either positive or negative contexts. Although explanations in a negative context can be selected depending on the medical situation, identification of patients who will choose the treatment with explicit statistical prediction after an explanation in a negative context is important; personality traits are related to these emotional decisions. Therefore, in the present study, we examined the personality traits associated with choice of treatment with explicit statistical prediction after an explanation in a negative context. Patients and Methods A total of 147 patients with glaucoma were recruited for this study. The questionnaire booklets used contained positively framed or negatively framed versions of an "Asian disease problem" to enable examination of the influence of the way in which a problem is framed (framing effect) on the participants' decision-making. The Japanese version of the Ten-Item Personality Inventory was used to estimate the personality traits of the participants. Results Low conscientiousness was identified as the only variable that was strongly predictive of the choice of treatment with explicit statistical prediction (β = -0.44, z = 2.19, p = 0.03). In addition, while the association was not statistically significant, low neuroticism was found to be weakly predictive of the choice of uncertain treatment (β = -0.37, z = 1.73, p = 0.08). Conclusion In conclusion, we showed that low levels of conscientiousness predict the choice of treatment with explicit statistical prediction (ie, topical treatment) for glaucoma after an explanation in a negative context.

Abstract
Morita therapy (MT) has been re-evaluated and has attracted much attention internationally to date. However, it is not known what kinds of experiences inpatients with mood disorders undergo during the process of recovery through MT. The purpose of this study was therefore to empirically clarify what subjective experiences influence the recovery from depression when it is treated with MT. Patients with mood disorders who were admitted to the Jikei University Center for Morita Therapy were included. Successive assessments of depression were performed using rating scales. Semi-structured interviews were conducted at the time of discharge regarding factors contributing to improvement, and were analyzed using qualitative data analysis methods to identify factors contributing to the recovery from depression among inpatients treated with MT. There were 24 subjects, 19 of whom completed treatment. The completers had significantly lower severity of depression severity upon discharge. Remarkably, qualitative analysis revealed that nine categories of experiences contributed to recovery from depression. In particular, experiences of "isolation bed-resting of MT", "getting stuck in doing things one's way", "identifying maladaptive behavior patterns", "modifying maladaptive behavior patterns", "restoring self-evaluation", and "change in negative emotions" were considered as the key experiences for recovery.

Abstract
Recently, addiction to regular doses of hypnotics has become a problem. While many patients report a desire to reduce their dosage, many do not agree with their physicians' suggestions for reduction. In this study, we created an online short video targeting patient motivation to reduce hypnotics usage and examined its efficacy and factors associated with the intention to reduce medication. We created a 10 min video that included "sleep education," "guidance for reducing the use of hypnotics," and "systematic motivation for reducing the use of hypnotics" and posted it on our website. For 1 year, we conducted a questionnaire survey to determine the effectiveness of the video and factors associated with the intention to reduce hypnotics use. Of 4548 viewers, 609 (13.4%) completed the questionnaire, 369 (67.9%) of whom used hypnotics. Most respondents were older adults. The intention to reduce medication use was significantly strengthened after watching the video in 37.7% of medication users (effect size 0.404). In the group that was not inclined toward medication reduction before viewing, 85.2% of patients had stronger intentions to reduce medication use after watching the video (effect size 0.818). "Memorable content about side effects" was extracted as a factor related to reinforcement of the intention to reduce medication use, suggesting that prescribing physicians' descriptions of current insomnia treatment is inadequate in explaining side effects to patients. A short informational video can have beneficial effects on patients' motivation for dose reduction or cessation of hypnotics. Supplementary Information The online version contains supplementary material available at 10.1007/s41105-023-00446-4.

Abstract
BACKGROUND This study aimed to evaluate the effects of medical fee revisions aimed to reduce psychotropic polypharmacy in Japan on the proportion of psychotropic polypharmacy in discharge prescriptions for patients with major depressive disorder (MDD) or bipolar disorder (BD) using a nationwide inpatient database. METHODS In this retrospective cohort study, we used the Diagnosis Procedure Combination database to identify patients with MDD or BD discharged between April 2012 and March 2021. We targeted medical fee revisions in October 2014, April 2016, and April 2018. The major outcome was the monthly proportion of psychotropic polypharmacy in prescription at discharge using the criteria following the April 2018 revision (antidepressants ≥3, antipsychotics ≥3, anxiolytics ≥3, hypnotics ≥3, or sum of anxiolytics and hypnotics ≥4). We performed interrupted time series analyses to evaluate the changes in level and trend between pre- and post-revisions. RESULTS We identified 63,289 and 33,780 patients with MDD and BD respectively in the entire study period. In both the patient groups, there were significant decreases in the proportion of psychotropic polypharmacy at revision in October 2014, and no significant trend and level change at revision were observed in April 2016 and April 2018, with a few exceptions. CONCLUSIONS The medical fee revisions aimed to reduce psychotropic polypharmacy in Japan might have had a limited impact on discharge prescriptions for patients with MDD and BD.

Abstract
OBJECTIVES Older adults tend to experience decreased enjoyment and fulfillment in life, social interactions, and independent living, with aging. These situations often result in lower levels of daily living self-efficacy in activities, which is one of the factors resulting in a decline in the quality of life (QOL) among older individuals. For this reason, interventions that help maintain daily living self-efficacy among older adults may also help maintain a good QOL. The objective of this study was to develop a daily living self-efficacy scale for the elderly that can be used to evaluate the effects of interventions aimed at enhancing self-efficacy. METHODS An expert meeting involving specialists in dementia treatment and care was held, to prepare a draft for a daily living self-efficacy scale. In the meeting, previous studies on self-efficacy among older adults, which were collected in advance, were reviewed, and the experiences of the specialists were discussed. Based on the reviews and discussions, a draft of a daily living self-efficacy scale comprising 35 items was prepared. This study on daily living self-efficacy was conducted from January 2021 to October 2021. The internal consistency and concept validity of the scale were evaluated based on the assessment data. RESULTS The mean age ± standard deviation of the 109 participants was 84.2 ± 7.3 years. The following five factors were extracted based on factor analysis: Factor 1, "Having peace of mind"; Factor 2, "Maintaining healthy routines and social roles"; Factor 3, "Taking personal care of oneself"; Factor 4, "Rising to the challenge"; and Factor 5, "Valuing enjoyment and relationships with others". The Cronbach's alpha coefficient exceeded 0.7, thereby suggesting sufficiently high internal consistency. Covariance structure analysis confirmed sufficiently high concept validity. CONCLUSIONS The scale developed in this study was confirmed to be sufficiently reliable and valid, and when used during dementia treatment and care to assess the levels of daily living self-efficacy among older adults, it is expected to contribute to the improvement of QOL among older adults.

Abstract
An 84-year-old woman who had been diagnosed as having dementia with Lewy body (DLB) upon initial examination exhibited cognitive impairments and person delusional misidentification (DMS): she transiently claimed that her spouse was a stranger. She was re-examined at the age of 89 years; her frequency of speech and activities of daily living had both decreased, leading to verbal communication difficulties complicated by sensory aphasia, and brain diffusion-weighted (DW) magnetic resonance imaging (MRI) showed cortical hyperintensities in some areas of both hemispheres. About 4 months later, the DW high-intensity areas were observed to have expanded into diffuse cortical areas. While the clinical features of Creutzfeldt Jakob disease (CJD) (myoclonus; ataxia; parkinsonism; rapidly progressive cognitive impairments; periodic sharp discharges on electroencephalograms) were not observed, a genetic analysis of the prion protein (PRNP) gene, which was performed because of a family history of dementia, revealed a V180I mutation (heterozygosis: valine/isoleucine) suggesting genetic CJD (g-CJD). Her activity progressively decreased, reaching akinetic mutism about 11 months after the re-examination. Finally, she suffered from severe bedsores and died from aspiration pneumonia at the age of 90 years. The present report describes the first case of person DMS as an initial neuropsychiatric symptom for V180I g-CJD; the typical long-term clinical symptoms of CJD were not observed in this patient. The inclusion of person DMS as an initial clinical symptom and the presence of expansive cortical hyperintensity areas may be useful for clinicians attempting to diagnosis V180I g-CJD in patients with elusive symptoms.

Abstract
AIM Medication adherence is important for achieving functional recovery from schizophrenia and is commonly assessed using the Drug Attitude Inventory-30 (DAI-30). Subscales of the DAI-30, including "awareness of the need for medication," "awareness of the effects of psychiatric drugs," and "impression of medication," have been used to assess medication adherence. To determine which of these subscales are associated with the prognosis of schizophrenia, this study followed patients with schizophrenia to identify the prognosis and examine the subscales related to "recovery." METHODS In total, 89 patients were recruited, 78 of whom were registered in the study. After assessing adherence using the DAI-30, Positive and Negative Syndrome Scale and Global Assessment of Functioning scores were assessed at 0 and 24 week to define the functional prognosis. RESULTS At the end of the 24-week follow-up period, 36% of patients showed recovery from schizophrenia. A comparison of subscales revealed that the score for "impression of medication" was significantly higher in the recovery than in the non-recovery group. Logistic regression analysis identified only the "impression of medication" score as being predictive of recovery. CONCLUSION The results indicated that among the three DAI-30 subscales, "impression of medication" was the most closely associated with recovery in patients with schizophrenia.

Abstract
Cognitive behavioral therapy for insomnia (CBT-I) is effective for not only primary insomnia (PI) but also comorbid insomnia (CI; insomnia associated with psychiatric/physical diseases or other types of sleep disorders). This study aimed to compare the outcomes of CBT-I implemented in the same manner between patients with PI and CI. In total, 41 adult patients who had completed CBT-I were enrolled in this retrospective analysis and divided into a PI group and a CI group. The authors then examined and compared the significance of changes after therapy between the two groups. The magnitude of improvement on the Japanese version of the Insomnia Severity Index (ISI-J) was analyzed as the primary endpoint. In the PI group (n = 24), both the ISI-J score and the dose of hypnotics decreased significantly following CBT-I. On the other hand, in the CI group (n = 17), only the dose of hypnotics decreased significantly; no statistically significant improvement was seen in the ISI-J score. Sleep onset latency and sleep quality rating in recorded sleep diaries were significantly correlated with improved ISI-J scores in the CI group only. CBT-I was shown to be effective for CI, but its efficacy for CI was inferior to that for PI in terms of impact on sleep and mental condition. These results suggest that in addition to the basic components of CBT-I, treatment for CI, especially when accompanied by severe insomnia symptoms, should include approaches targeting the comorbid disease.

Abstract
Patients with major depressive disorder (MDD) exhibit several clinical symptoms including difficulties in flexible thinking. Flexible thinking mainly relies on a cognitive ability called shifting; however, the mechanisms underlying shifting in patients with MDD have not yet been clarified. Therefore, we conducted a preliminary intervention study to clarify the association between depression and shifting ability. We examined the hemodynamic responses in the frontal regions during the shifting task using functional near-infrared spectroscopy (fNIRS) in 21 patients with MDD who were treated using high-frequency repetitive transcranial magnetic stimulation (rTMS). Behavioral performance on the shifting task did not change between pre- and posttreatments, whereas patients who responded well to rTMS treatment showed a significant decrease in hemodynamic responses posttreatment. On the other hand, the poor responders did not show significant changes in the hemodynamic responses between pre- and posttreatments. These results suggest that the good responders were successfully remedied with rTMS treatment and did not need effortful activity in frontal regions for shifting, which made their brain activity more efficient.

Suppressors of Cytokine Signaling Are Decreased in Major Depressive Disorder Patients. J Pers Med 2022; 12:jpm12071040. [PMID: 35887537 PMCID: PMC9315526 DOI: 10.3390/jpm12071040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 06/23/2022] [Accepted: 06/24/2022] [Indexed: 12/01/2022] Open
Abstract
There is strong evidence for an association between major depressive disorder (MDD) and inflammation. However, some studies have not observed an increase in inflammatory cytokines in MDD, and the mechanism behind this is unknown. In the present study, we evaluated MDD severity using the Montgomery–Åsberg Depression Rating Scale (MADRS) and quantified mRNA levels of the blood inflammatory cytokines interleukin (IL) 1β, IL-6 and tumor necrosis factor alpha (TNF-α), as well as negative regulators of cytokine signaling—comprising IL-10, IL-1RA, SOCS1, SOCS2 and SOCS3—in MDD patients (n = 36), with a focus on mild MDD, and normal controls (NC, n = 30). We also measured the serum levels of IL-1β and IL-6. Neither the blood mRNA nor the protein levels of inflammatory cytokines were significantly elevated in the MDD group compared with the NC group. However, we observed significant decreases in SOCS1, SOCS2 and SOCS3 mRNA in the MDD group compared to the NC group. A significant finding was a decrease in SOCS3 mRNA after remission from MDD, suggesting that SOCS3 is a trait marker in depressive symptoms. We consider that our findings would be useful in elucidating the pathophysiological mechanism of depression.

Abstract
Background Aesthetically unappealing adverse periocular reactions to prostaglandin (PG) eye-drops are a major challenge in glaucoma treatment. This study analysed the personality traits of patients with glaucoma based on a five-factor model and examined the associations between these factors and adverse periocular reactions. Methods One hundred and forty-seven patients with glaucoma were surveyed anonymously regarding their personality traits and how often adverse periocular reactions were experienced. Results The analysis included 117 valid responses (71 men and 46 women, age: 61.9±11.5 years). Patients who experienced hypertrichosis of the eyelashes scored significantly higher on extraversion (p<0.05), with no significant differences in the other four personality traits. Patients who experienced eyelid hyperpigmentation and deepening of the upper eyelid sulcus showed no significant differences in any of the personality traits. Younger patients scored significantly higher on hypertrichosis (p<0.05). Conclusion The experience of adverse reactions differed according to patient age and personality traits. Therefore, eye-drops should be chosen based on these factors. Trial registration number UMIN000035155.

Abstract
BACKGROUND It is important to make accurate clinical diagnosis of frontotemporal lobar degeneration (FTLD), which in turn, leads to future therapic approaches. The FTLD cases are frequently inaccurately identified, but the frequency of this misidentification according to the underlying pathological subtypes is still unclear. OBJECTIVE We aimed to quantify the accuracy of behavioral variant frontotemporal dementia (bvFTD) and semantic variant primary progressive aphasia (svPPA) diagnoses by both the patients' referring physicians and hospital expert psychiatrists, and we investigated whether the physicians' and psychiatrists' diagnostic patterns are associated with a specific neuropathology. METHODS We retrospectively analyzed the cases of a series of Japanese patients with pathologically diagnosed FTLD (n = 55): the bvFTD group (n = 47) consisted of patients with FTLD-tau (n = 20), FTLD-TDP (TAR DNA-binding protein of 43-kDA) (n = 19), and FTLD-FUS (fused in sarcoma) (n = 8). The svPPA patients (n = 8) all had FTLD-TDP. RESULTS Only 31% of the patients' referring physicians mentioned FTD syndrome. The referring psychiatrists and neurologists showed similar diagnostic accuracy. High diagnostic accuracy was observed for the TDP pathology group (mainly svPPA patients). The FTLD-FUS patients were more likely to be diagnosed as having a psychiatric disorder by referring physicians. The hospital expert psychiatrists' accuracy for identifying FTLD-tau pathology was low. CONCLUSION The results of our analyses revealed a specific diagnostic pattern associated with particular FTLD pathological subtypes, which will help to improve non-specialists' diagnostic ability.

Abstract
Aim Suicide attempts are an important severe psychiatric symptom and a clear outcome for mental disorders. Although the relationship between the early repolarization pattern in electrocardiogram and psychiatric disorders has recently been reported, these reports have not been able to exclude the influence of psychiatric drugs. This study aimed to investigate the relationship between the early repolarization pattern and a history of suicide attempts among patients not receiving psychiatric medication. Methods A total of 71 patients with a history of suicide attempts were investigated, 38 of whom were analyzed for this study. We compared the frequency of the early repolarization pattern between a suicide attempt group and a control group. Then, we investigated the association between the early repolarization pattern and the suicide attempt group by logistic regression analysis, including electrocardiographic findings associated with psychiatric disorders. Results The findings indicated that the frequency of the early repolarization pattern was significantly higher in the suicide attempt group (n = 20; 52.6%) than in the control group (n = 4; 10.5%) (P < 0.001), and the results of the logistic regression analysis indicated that the early repolarization pattern was associated with suicide attempts. Conclusions These findings suggest that the early repolarization pattern is associated with a history of suicide attempts.

Education level is associated with neuropsychiatric symptoms in patients with amnestic-mild cognitive impairment. Psychogeriatrics 2022; 22:343-352. [PMID: 35181960 DOI: 10.1111/psyg.12818] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 01/18/2022] [Accepted: 01/28/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND We examined differences in the severity of neuropsychiatric symptom (NPS) subsyndromes according to education level among patients with amnestic-mild cognitive impairment (a-MCI) with the aim of identifying patient demographics related to NPS subsyndromes. METHODS Overall, 140 patients with a-MCI were included. We divided the patients into three groups according to their educational level (primary education, middle education, and high education) and compared their demographics. To explore the severity of NPS subsyndromes according to educational level, we used the Neuropsychiatric Inventory (NPI) after adjustments for the Mini-Mental State Examination (MMSE) score. Finally, NPS subsyndromes that were identified as being related to educational level were further explored using a general linear model (GLM). RESULTS Significant differences in several demographics were observed among the three groups. Among the NPS subsyndromes, the scores for aggressiveness were significantly higher in the primary and high education groups than in the middle education group, while the apathy/eating problem scores were significantly higher in the primary education group than in the other groups. The GLM analyses showed that aggressiveness was related to marital status and the Zarit Caregiver Burden Interview (ZBI-J) score, while apathy/eating problems were related to the instrumental activities of daily living (IADL) percentage, the ZBI-J score, and the education level in years. CONCLUSIONS Among NPS subsyndromes, aggressiveness and apathy/eating problems differed according to education level in patients with a-MCI. A GLM analysis suggested that not only education level, but also various other factors should be considered when determining the need for NPS interventions.

Abstract
Objectives: We examined the clinicodemographic and psychosocial factors that relate to the presentation and severity of delusions of theft among female patients with amnestic mild cognitive impairment (a-MCI) and Alzheimer's disease (AD).Methods: We enrolled a total of 177 female patients with a-MCI or AD, of whom 40 presented with delusions of theft. We compared the differences in clinicodemographic and psychosocial factors of the 40 patients (delusions of theft group) with 50 age- and Mini-Mental State Examination (MMSE)-matched controls without delusions (control group). Furthermore, we identified the factors associated with the presentation of delusions of theft using a general linear model (GLM). The severity of delusions of theft was calculated using the Neuropsychiatric Inventory Questionnaire, and correlations between the clinicodemographic and psychosocial factors were examined.Results: Between the two groups, the delusions of theft group had lower scores on the Physical Self-Maintenance Scale and instrumental activities of daily living (IADL) and higher scores on the Japanese version of the Zarit Caregiver Burden Interview (ZBI-J) than the control group. GLM analysis revealed that the IADL score was related to the presentation of delusions of theft. The severity of delusions of theft correlated with the MMSE and the ZBI-J scores in the delusions of theft group.Conclusions: The two groups had several differences regarding clinicodemographic and psychosocial factors. Furthermore, lower IADL scores were related to symptom presentation. Symptom severity correlated with cognitive functioning and caregiver burden.Clinical Implications: In the determination of treatment or care, differences in these factors should be considered.

Laterality of prefrontal hemodynamic response measured by functional near-infrared spectroscopy before and after repetitive transcranial magnetic stimulation: A potential biomarker of clinical outcome. Psychiatry Res 2022; 310:114444.

Abstract
The factors associated with the clinical outcomes of repetitive transcranial magnetic stimulation (rTMS) in patients with major depressive disorder (MDD) remain largely unexplored. Therefore, this study aimed to examine whether rTMS can change the functional laterality of the prefrontal hemodynamic response and whether baseline functional laterality can predict the clinical outcomes of rTMS using functional near-infrared spectroscopy (fNIRS). We included 19 patients with MDD who were treated with high-frequency rTMS. The verbal fluency task was used as the activation task. We calculated the laterality index (LI) based on the task-related oxygenation response in the frontal region. First, the LI was compared before and after rTMS treatment. Second, the reduction in the Montgomery-Åsberg Depression Rating Scale (MADRS) score was compared between the rightward dominance group (pre-LI < 0) and the leftward dominance group (pre-LI ≥ 0). The findings showed a significant change in the LI after rTMS treatment. The rightward dominance group had a significantly greater reduction in MADRS score than the leftward dominance group. Subsequently, the laterality of the task-related hemodynamic response of the prefrontal region shifted leftward following left high-frequency rTMS treatment. Thus, the pre-LI calculated using fNIRS data is a possible predictor of rTMS outcomes in patients with MDD.

Abstract
INTRODUCTION Repetitive transcranial magnetic stimulation (rTMS) has been employed worldwide for therapy-resistant depression. The Food and Drug Administration has approved a number of therapeutic devices for treating major depressive disorder; however, no studies have examined the differences in efficacy and acceptability among commercially available stimulation devices. The aim of our study was to compare the efficacy and acceptability of 3 stimulation devices (NeuroStar, MagPro, and Magstim) for depressive disorders. METHODS Our study included 31 randomized sham-controlled trials of high-frequency rTMS included in the network meta-analysis by Brunoni. We calculated the risk ratio and 95% confidence intervals, comparing each device with sham for the endpoints of response rate, remission rate, and all-cause discontinuation. We then analyzed the differences among the devices in effect size for those endpoints. RESULTS After determining the effect sizes for the endpoints, we found no statistically significant subgroup differences in the response rates, all-cause discontinuation, or remission rates among the devices (p = 0.12, p = 0.84, and p = 0.07, respectively). CONCLUSION Our results suggest similar efficacy and acceptability for the 3 stimulation devices. Future studies need to perform head-to-head comparisons of the efficacy and acceptability of the stimulation devices for treating depression using the same stimulation protocols.

Abstract
Aim Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique that shows potential for treating psychiatric disorders. Although several studies have sought to investigate new TMS modalities for the treatment of various psychiatric disorders, no study has yet examined publication trends in research on TMS modalities for psychiatric disorders. This study investigated publication trends in TMS research for 13 psychiatric disorders, including addiction, dementia, major depressive disorder (MDD), and obsessive‐compulsive disorder (OCD), and schizophrenia, as well as 9 TMS modalities, including bilateral stimulation, deep TMS, high‐frequency stimulation, low‐frequency stimulation, and theta burst stimulation. Methods Articles published in PubMed from 1985 to 2019 were searched to determine the number of published articles for each year in each category using the “Results by year” tool from the PubMed database. Results Over the past 30 years, an increasing number of articles were published regarding TMS research for the treatment of MDD, addiction, and dementia, which were among those most commonly investigated psychiatric disorders, whereas the number of articles addressing schizophrenia and OCD treated via TMS remained steady since 2015. Regarding TMS modalities, previous high‐frequency stimulation, low‐frequency stimulation, and bilateral stimulation were the most common topics, with research regarding deep TMS and theta burst stimulation having increased since 2000 and 2005, respectively. Conclusion TMS applications are rapidly developing and becoming increasingly ubiquitous in various psychiatric disorders. Determining publication trends in TMS research can be a useful method for monitoring TMS research interests and applications of new TMS modalities for psychiatric disorders.

Abstract
AIMS Patients with severe behavioral and psychological symptoms of dementia (BPSD) are often admitted to mental hospitals, while, inpatient care could also lead to prolonged hospital stay. The present study aims to survey clinical profiles of patients who required inpatient treatment for BPSD, and then establish the criteria for introducing inpatient treatment through assessment by certified psychiatrists. METHODS We performed a prospective survey about clinical characteristics of people with dementia who required treatment of BPSD at 12 mental medical institutions. All patients were assessed by certified psychiatrists to determine the optimal treatment settings: outpatient or inpatient. The multivariate logistic regression analysis was performed to specify factors contributed to the judgement of clinicians. Subsequently, the receiver operating characteristic curve analysis was conducted to explore a score derived from the Neuropsychiatric Inventory to divide patients into outpatient or inpatient groups. RESULTS The present study included 386 patients, of which 242 were admitted to mental hospitals. BPSD were classified into four domains, and aggressive BPSD was significantly associated with assessment for inpatient treatment; the adjusted odds ratio was approximately 2 regardless of dementia severity. Furthermore, the composite score of agitation, irritability and aberrant behavior showed the highest area under the curve value (=0.706), which differentiated inpatients from outpatients with a sensitivity of 76% and a specificity of 54%. CONCLUSIONS Aggressive BPSD was the risk factor for inpatient treatment. The composite score of the Neuropsychiatric Inventory subdomain-related aggressive BPSD could be a screening tool to introduce inpatient treatment for BPSD. Geriatr Gerontol Int 2021; 21: 825-829.

Abstract
Background: Behavioral and psychological symptoms of dementia (BPSD) cause a heavy burden for both patient and caregivers. These symptoms are diverse, and their mechanism is still unclear. Agitation is the most common and difficult to treat among BPSD. In recent years, while changes in DNA methylation levels have been receiving attention as a biomarker of aging and dementia, associations with BPSD have not been examined. Objective: Focusing on agitation, the objective of the present study was to identify a region where changes in DNA methylation levels are associated with agitation. Methods: Using genome-wide DNA methylation analysis data for 7 dementia subjects with agitation, 5 dementia subjects without agitation, and 4 normal elderly controls, we determined a signaling pathway in the WNT5A gene promoter region to be associated with agitation. Based on this result, we measured DNA methylation levels in this region for 26 dementia subjects with agitation and 82 dementia subjects without agitation by means of methylation-sensitive high-resolution melting (MS-HRM) analysis. Results: The WNT5A DNA methylation level in dementia subjects with agitation was significantly lower than in those without agitation (p = 0.001). Changes in WNT5A DNA methylation levels were not influenced by age, sex, body mass index, APOE ɛ4, medication, or inflammatory cytokines. Conclusion: Our results suggested an association of agitation with Wnt signaling, in particular with changes in WNT5A DNA methylation levels, which could be a potentially useful biomarker for predicting the appearance of agitation. It may contribute to the elucidation of the mechanism of BPSD.

Abstract
OBJECTIVES Major depression is a highly prevalent disorder that causes economic burden in office workers. We conducted a randomized, double-blind, sham-controlled trial to evaluate the efficacy and safety of deep transcranial magnetic stimulation (dTMS) in office workers with treatment-resistant depression. METHODS In this study, we randomized office workers taking administrative leave for treatment-resistant major depressive disorder or bipolar disorder with current major depressive episode. dTMS treatment was applied at 120% resting motor threshold with 18 Hz over the left dorsolateral prefrontal cortex. The treatment sessions delivered a total of 1,980 pulses a day, 5 days a week, for 4-6 weeks. The primary outcome was change in the total score on the 21-item Hamilton Depression Rating Scale (HDRS-21) from baseline to the end of study in an intent-to-treat analysis. The secondary outcomes were the response and remission rates. We also assessed changes in cognitive function and adverse events. RESULTS Forty patients were randomized to active or sham dTMS groups (1:1). The change in the total score on the HDRS-21 was more significantly improved in the active group than in the sham group at 6 weeks (p = 0.045). There were no significant differences in the response and remission rates or cognitive measures between the active and sham groups. No serious adverse events were observed in either group. CONCLUSIONS These results suggest that dTMS might be effective and safe in office workers with treatment-resistant depression. Further well-designed studies are needed.

Abstract
A panel of radiochemicals has enabled in vivo positron emission tomography (PET) of tau pathologies in Alzheimer's disease (AD), although sensitive detection of frontotemporal lobar degeneration (FTLD) tau inclusions has been unsuccessful. Here, we generated an imaging probe, PM-PBB3, for capturing diverse tau deposits. In vitro assays demonstrated the reactivity of this compound with tau pathologies in AD and FTLD. We could also utilize PM-PBB3 for optical/PET imaging of a living murine tauopathy model. A subsequent clinical PET study revealed increased binding of 18F-PM-PBB3 in diseased patients, reflecting cortical-dominant AD and subcortical-dominant progressive supranuclear palsy (PSP) tau topologies. Notably, the in vivo reactivity of 18F-PM-PBB3 with FTLD tau inclusion was strongly supported by neuropathological examinations of brains derived from Pick's disease, PSP, and corticobasal degeneration patients who underwent PET scans. Finally, visual inspection of 18F-PM-PBB3-PET images was indicated to facilitate individually based identification of diverse clinical phenotypes of FTLD on a neuropathological basis.

Abstract
Introduction Schizophrenia is believed to be etiologically associated with environmental factors. Poor parental bonding, especially arising from “low care” and “overprotection,” may contribute to the prognosis in patients with psychosis. In the present study, we investigated the associations between the aforementioned two different parental bonding types and the prognosis, in terms of the functional recovery, of patients with schizophrenia. Methods A total of 89 patients with schizophrenia were recruited, and 79 patients were registered for the study. After the parental bonding types and representative childhood adverse events were assessed, specific items on the PANSS were assessed at 0 and 24 weeks of the study period to define the functional prognosis. Results At the end of the 24-week follow-up period, 36% of the patients were judged as showing recovery from schizophrenia. The score for “overprotective attitude,” but not that for “low care,” was found to be significantly higher in the non-recovery (defined below) group. Exploratory logistic regression analysis identified only “overprotective attitude” of the parents as being predictive of non-recovery. Moreover, a significant negative correlation was found between “low care” and “overprotective attitude” only in the non-recovery group. Conclusion In the present study, we showed that an overprotective attitude of the parents was associated with non-recovery in patients with schizophrenia.

Efficacy of yokukansan compared with clonazepam for rapid eye movement sleep behaviour disorder: a preliminary retrospective study. Psychogeriatrics 2020; 20:681-690. [PMID: 32478914 DOI: 10.1111/psyg.12563] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Revised: 04/10/2020] [Accepted: 04/24/2020] [Indexed: 12/14/2022]
Abstract
AIM Rapid eye movement sleep behaviour disorder (RBD) is characterized by abnormal behaviours accordant with nightmares during rapid eye movement sleep and is considered a prodromal marker of dementia with Lewy body. Most common in the elderly population, RBD is generally treated with clonazepam (CZP), a long-term acting benzodiazepine antiepileptic. As such, alternative drugs for RBD are urgently needed to minimize the adverse effects peculiar to benzodiazepines. The efficacy of yokukansan (YKS), a traditional Japanese herbal medicine, on RBD was initially reported by Shinno et al. in 2008. However, no study has compared YKS with CZP. Therefore, this study aimed to clarify the possibility of using YKS as an alternative to CZP. METHODS This was a retrospective cohort study conducted at Jikei University Affiliated Hospital. The subjects were selected from 36 outpatients who had been diagnosed with RBD based on the International Classification of Sleep Disorders, third edition. Of the 23 who met the inclusion criteria but not the exclusion criteria, 11 were treated with YKS monotherapy, and 12 were treated with CZP monotherapy. The primary outcome was the total score on the Japanese version of the Rapid Eye Movement Sleep Behaviour Disorder Questionnaire (RBDQ-JP), and the secondary outcomes were the scores from the eight-item Short-Form Health Survey and factors 1 and 2 of the RBDQ-JP. RESULTS The mean total RBDQ-JP score significantly improved from 52.5 to 21.7 (P = 0.002) after treatment with YKS (mean dosage: 3.0 g/day), which was similar to the change after CZP treatment (from 43.8 to 21.3). On RBDQ-JP factor 1 (dream content), the mean score on five of six items significantly improved after treatment with YKS. There was no significant change in Short-Form Health Survey scores after treatment with either drug. Potassium concentrations were within the normal range in patients treated with YKS. CONCLUSIONS The present results suggest that a small amount of YKS may be an alternative to CZP for RBD, without remarkable adverse events. Further study is needed to prospectively clarify the efficacy and safety of YKS in more detail.

Inter-method reliability between automatic region of interest analytic application with multi-atlas segmentation and FreeSurfer. Psychogeriatrics 2020; 20:699-705. [PMID: 32510746 DOI: 10.1111/psyg.12567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 04/29/2020] [Accepted: 05/04/2020] [Indexed: 12/01/2022]
Abstract
AIM Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by the aggregation of amyloid-β and phosphorylated tau proteins. Magnetic resonance imaging (MRI) is a useful means of detecting hippocampal atrophy. However, instead of visual inspection, objective and time-saving tools for automated region of interest (ROI) analysis are needed. Advances in MRI segmentation techniques have enabled a multi-atlas approach with fewer errors than a conventional single-atlas approach. To support the clinical application of multi-atlas segmentation, an automated ROI analytic application consisting of multi-atlas segmentation with joint label fusion and corrective learning was developed: T-Proto. In the present study, we evaluated the inter-method reliability between T-Proto and a reference ROI analytic software, FreeSurfer. METHODS This was a database study. MRI data from 30 patients with AD were selected, and the inter-method reliability was assessed in terms of the intra-class correlation coefficient (ICC). A post-hoc comparison according to the severity of AD was also performed. RESULTS Almost all the regional volumes estimated with T-Proto were smaller than those estimated with FreeSurfer. The regional ICC values between the two methods showed moderate to excellent reliability. A post-hoc comparison revealed a similar t-value and effect size between both methods for the hippocampus. CONCLUSION In the present study, we showed that automated regional analysis using T-Proto was reliable in the hippocampus in terms of ICC, compared with FreeSurfer.

Increased blood COASY DNA methylation levels a potential biomarker for early pathology of Alzheimer's disease. Sci Rep 2020; 10:12217. [PMID: 32699290 PMCID: PMC7376092 DOI: 10.1038/s41598-020-69248-9] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Accepted: 07/07/2020] [Indexed: 01/12/2023] Open
Abstract
Early diagnosis of dementia including Alzheimer's disease (AD) is an urgent medical and welfare issue. However, to date, no simple biometrics have been available. We reported that blood DNA methylation levels of the COASY gene, which encodes coenzyme A synthase, were increased in individuals with AD and amnestic mild cognitive impairment (aMCI). The present study sought to replicate these findings with larger numbers of samples. Another objective was to clarify whether COASY methylation is associated with neurodegeneration through a comparison of AD, AD with cardiovascular disease (CVD), and vascular dementia (VaD). We measured blood COASY methylation levels in normal controls (NCs) (n = 200), and individuals with aMCI (n = 22), AD (n = 151), and VaD (n = 21). Compared with NCs, they were significantly higher in individuals with aMCI and AD. Further, they were significantly higher in AD patients without cardiovascular diseases compared to AD patients with them. These findings suggest that COASY methylation levels may be related to neurodegeneration in AD.

Abstract
Little is known about the effect of latent-phase herpesviruses on their host. Human herpesvirus 6B (HHV-6B) is one of the most ubiquitous herpesviruses, and olfactory astrocytes are one of the most important sites of its latency. Here, we identified SITH-1, an HHV-6B latent protein specifically expressed in astrocytes. Mice induced to produce SITH-1 in their olfactory astrocytes exhibited olfactory bulb apoptosis, a hyper-activated hypothalamic-pituitary-adrenal (HPA) axis and depressive symptoms. The binding of SITH-1 to the host protein calcium-modulating ligand (CAML) to form an activated complex promoted the influx of extracellular calcium. The serum antibody titers for depressive patients with respect to this activated complex were significantly higher than for normal controls (p = 1.78 × 10−15), when the antibody positive rates were 79.8% and 24.4%, respectively, and the odds ratio was 12.2. These results suggest that, in the latent phase, HHV-6B may be involved in the onset of depression. We identified SITH-1, a new protein specific to HHV-6B latent infection Mice expressing SITH-1 at HHV-6B latent infection site had depressive symptoms Depressive symptoms due to SITH-1 were associated with a hyper-activated HPA axis SITH-1-specific antibody detection significantly greater in depressive patients

Anosognosia in patients with Alzheimer's disease: current perspectives. Psychogeriatrics 2020; 20:345-352.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disease characterised by neurocognitive impairments, especially memory impairment, as core symptoms linked to reductions in activities of daily life. As marginal symptoms, neuropsychiatric symptoms (NPSs) appear during the progressive course of the disease. A lack of self-awareness (anosognosia) of cognitive and functional impairments is often seen in patients with AD, and associations between anosognosia and other NPSs have been previously reported. To account for anosognosia pathogenesis neurocognitively, the cognitive awareness model (CAM) has been helpful for explaining the stream of events from sensory input to behavioural/affective and metacognitive outputs. According to CAM, there are three types of anosognosia: (i) primary anosognosia, (ii) executive anosognosia, and (iii) mnemonic anosognosia. These types of anosognosia are generated from different neurocognitive modulations leading to metacognitive outputs or behavioural/affective regulations. Primary anosognosia is considered to be caused by deficits in the metacognitive awareness system (MAS). While preserved MAS function is associated with milder depression and anxiety in AD, a severer depressive mood in patients with mild AD can inversely cause self-underestimation. The modulation of executive anosognosia is thought to be associated with dangerous/disinhibition behaviours and apathy among NPS sub-symptoms, via impairments of comparator mechanism (Cm) within the central executive system. Other neurobehavioral reactions linked to self-awareness include 'denying' and 'confabulation', and each of these reactions is thought to be affected by the MAS and a Cm. Denial of one's own memory impairments appears as a defensive reaction to protect against dysphoric feelings, and the confabulatory comment is instantly reaction constructed by fabrications according to misinterpretations of memory information about oneself. Similarly, the innovative development of a theoretical model (CAM) has contributed to explaining the mechanism of anosognosia and some neurobehavioral outputs from a neurocognitive perspective.

Abstract
AIM In patients with Alzheimer's disease (AD), cognitive impairments cause a progressive reduction in Activities of Daily Living (ADL). Neuropsychiatric symptoms (NPS) also appear in most patients; however, the association between NPS and reductions in ADL remains unclear. The present study evaluated whether NPS influence such reductions using two different ADL measures in patients with AD. METHODS Among 546 consecutive outpatients who visited the memory clinic at the Jikei University Kashiwa Hospital, we recruited 208 patients with AD and investigated the correlations between either the Physical Self-Maintenance Scale (PSMS) score or the Instrumental ADL (IADL) level, and each of the Behavioral Pathology in AD (Behave-AD) subscales. To clarify the causal relationships of these correlations, we then verified the associations between statistically significant demographic variables and the Behave-AD subscales as well as the two ADL scales (PSMS score and IADL percentage) using a general linear model. RESULTS Neither the PSMS nor the IADL results were significantly influenced by the aberrant motor behaviors score. However, the IADL was significantly influenced by the Mini-Mental State Exam (MMSE) score. Furthermore, diurnal rhythm disturbances and the interaction between diurnal rhythm disturbances score and the MMSE score significantly influenced the PSMS results. CONCLUSION Basic ADL reductions may be influenced by diurnal rhythm disturbances, in addition to cognitive impairments in patients with AD. Furthermore, the interaction between the diurnal rhythm disturbances score and cognitive function may also influence basic ADL. Geriatr Gerontol Int 2020; ••: ••-••.

Abstract
Objectives: We examined differences in the severity of neuropsychiatric symptoms (NPS) according to sex and identified NPS-related clinico-demographic and psychosocial factors among community-living patients with amnestic-mild cognitive impairment (a-MCI) or mild Alzheimer's disease (AD).Method: Overall, 111 patients (44 males, 67 females) with mild a-MCI (n = 64) or mild AD (n = 47) were included. We divided the patients according to sex and compared their clinico-demographic and psychosocial factors, explored the severity of NPS using the subscales from the Neuropsychiatric Inventory-Questionnaire (NPI-Q), and further identified variables related to NPS.Results: Significant differences in several clinico-demographic and psychosocial characteristics were observed between the sexes. The severity of delusions was higher among females (mean, 0.48; SD, 1.60) than males (mean, 0.23; SD, 1.07; p = .02), while the severity of irritability was higher among males (mean, 0.97; SD, 1.92) than females (mean, 0.49; SD, 1.40; p = .03). The severity of delusions among females was related to the duration of cognitive decline (B = 0.37, p = .03), while the severity of irritability among males was related to general cognition (B = -0.40, p = .003).Conclusion: The severity of NPS among patients with a-MCI or mild AD differed according to sex. We identified NPS-related clinico-demographic factors among these patients. Sex differences should be considered when determining the need for NPS interventions.

Abstract
Client motivation is regarded as a key to preventing violence behavior and positively affecting both patients and treatment staff in forensic psychiatric settings. We examined the correlation between client motivation for medical treatment and the quality of interprofessional teamwork. We surveyed 18 hospitalized forensic psychiatric patients using the IMI-J and CSQ-8J and 18 interprofessional teams from various professions using the r-CPAT, 6 and 12 months after the initial treatment. At 6 months, the correlation coefficients between the total r-CPAT scores and the total IMI-J and CSQ-8J scores were not significant. At 12 months, the correlation coefficients between the total r-CPAT scores and the total IMI-J or CSQ-8J scores were .33 and .11, respectively. The findings indicate that both clients' motivation and the quality of treatment provided by the interprofessional team improved over time. However, this study also showed that the professionals' subjective evaluation of the quality of interprofessional teamwork did not correlate with clients' subjective evaluation of satisfaction. In order to achieve client satisfaction, it is essential for professionals to address clients' needs in a timely manner and to prioritize effective communication to facilitate patient decision-making rather than merely providing advice.

Early Improvements of Individual Symptoms With Antipsychotics Predict Subsequent Treatment Response of Neuropsychiatric Symptoms in Alzheimer's Disease: A Re-Analysis of the CATIE-AD Study. J Clin Psychiatry 2020; 81.

Abstract
OBJECTIVE The aim of the present study was to identify individual symptoms whose early improvements contributed to subsequent treatment response to antipsychotics for neuropsychiatric symptoms (NPSs) in patients with Alzheimer's disease (AD) using the dataset of the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer's Disease (CATIE-AD). METHODS The CATIE-AD study was conducted between April 2001 and November 2004 at 45 sites in the United States. Data for 421 patients with DSM-IV AD with NPSs treated with antipsychotics were analyzed in the present study. Treatment response was defined as a reduction of ≥ 9 points in the Neuropsychiatric Inventory (NPI) score or a reduction of ≥ 25% from baseline in Brief Psychiatric Rating Scale (BPRS) total score at week 8. Logistic regression analyses were performed to examine associations between response and clinical and demographic characteristics, including each total or individual symptom score reduction at week 2. RESULTS Reduction in NPI or BPRS total score at week 2 and several individual symptom score reductions (euphoria/elation, irritability, hallucinations, anxiety, agitation, apathy, disinhibition, and depression among NPI subitems; excitement, suspiciousness, disorientation, hostility, depressive mood, and emotional withdrawal among BPRS subitems) at week 2 were significantly associated with subsequent treatment response at week 8 (all P values < .05); Early non-improvements of irritability and suspiciousness were shown to be especially influential clinical markers in predicting subsequent treatment nonresponse. Furthermore, healthier condition at baseline was significantly associated with treatment response at week 8 (P < .05). CONCLUSIONS Although further research to validate these preliminary findings is needed, focusing on early improvements of individual symptoms could help identify subsequent treatment responders to antipsychotics in AD patients with NPSs.

Abstract
Previous studies have shown that people with autistic traits have difficulties in motion perception, such as human gait as depicted on a point-light display. A recent study reported that adults with autism spectrum disorders showed atypical visual event-related evoked potentials (ERPs) in response to radial optic flow. To determine the correlation between gait perception and autistic traits in the general population, the present study recorded ERPs time-locked to the onset of approaching and receding point-light walkers. ERPs were measured using an 8-channel system in 19 adults and the correlation between the ERP components and the Subthreshold Autism Trait Questionnaire (SATQ) score were assessed to quantitatively measure autistic traits in the general population. The results showed that the higher SATQ score was, the longer the latency of the ERP component for an approaching walker was. In conclusion, people with autistic traits have trouble perceiving the approach of other people.
