RESUMEN
AIM: The Japanese Comprehensive Strategy to Accelerate Dementia Measures, known as the New Orange Plan, aims to support people with dementia living in their communities. Home-visit nurses (HVN) are expected to play an important role in this comprehensive support system. In this preliminary study, we explored caregivers' experiences before and after implementation of HVN care for persons with dementia who lived alone. METHODS: This study was a qualitative descriptive design using in-depth interviews with five family caregivers of persons with dementia who lived alone while receiving HVN. Thematic content analysis was undertaken. RESULTS: Before receiving HVN, caregivers experienced anxiety and embarrassment due to the occurrence of dementia symptoms, and they also experienced considerable isolation and anguish after hearing the diagnosis. After initiating HVN, caregivers gained a feeling of security and an alleviation of psychological stress. They also gained a deeper understanding of the disease and appropriate care for dementia patients. Notably, caregivers perceived not only positive changes in themselves, but also in the recipients, such as improvements in symptoms and quality of life. Finally, caregivers realized that people with dementia can live alone if appropriate services are provided. CONCLUSION: HVN can have a positive impact on family caregivers involved in dementia care, as well as on the recipients' psychological status. Overall, the experience of HVN made the family caregivers more positive about home care for their family member with dementia. Although further case studies are needed to make definitive conclusions, we believe that HVN could play a key role in the forthcoming New Orange Plan.

BACKGROUND: During hospitalization for behavioural and psychological symptoms of dementia (BPSD), it is imperative to build a support system for each patient in the community for after they obtain symptom remission. To this end, patients lacking adequate family support are less likely to be discharged to their own homes and need stronger support systems to be established. This study therefore investigated the effects of home-visit nursing before admission on time to home discharge among patients with limited familial care who were hospitalized for treatment of BPSD. METHODS: A single-centre chart review study was conducted on consecutive patients admitted from home between April 2013 and September 2015 for treatment of BPSD and who had lived alone or with a working family member. Time to home discharge was compared between patients who had home-visit nursing before their admission and those who did not. RESULTS: In total, 58 patients were enrolled in the study, of whom 12 had preceding home-visit nursing (PHN group) and 46 did not (non-PHN group). Patients in the PHN group were younger (77.7 ± 4.9 vs. 84.1 ± 6.1 years, P = 0.0011) and had higher Mini-Mental State Examination scores (16.8 ± 7.2 vs 11.8 ± 7.3, P = 0.0287). A multivariate Cox proportional hazard regression analysis adjusted for age and Mini-Mental State Examination scores showed a higher likelihood of discharge to home in the PHN group (hazard ratio: 3.85; 95% confidence interval: 1.27-11.6;, P = 0.017) than in the non-PHN group. CONCLUSION: Home-visit nursing before admission of BPSD patients for treatment could improve the rate of discharge to home among patients with limited familial care after subsequent hospitalization. Home-visit nursing could also enhance collaborative relationships between social and hospital-based care systems, and early implementation could improve the likelihood of vulnerable patient types remaining in their own homes for as long as possible.

BACKGROUND: Potentially harmful behaviour (PHB) by caregivers is detrimental to the physical and psychological well-being of care recipients. In Japan, few studies have investigated caregivers' PHB towards dementia patients. This study examined PHB in family caregivers of dementia patients with behavioural and psychological symptoms of dementia (BPSD) and identified factors related to PHB. METHODS: Following primary consultations at an elderly psychiatric patient department, we enrolled 133 pairs of dementia patients and their family caregivers. We assessed PHB using the Japanese version of the modified Conflict Tactics Scale. We defined the presence of PHB as two or more points (PHB frequency of 'sometimes' or more) on at least one indicator of the modified Conflict Tactics Scale. We investigated the prevalence of PHB in relation to the clinical characteristics of the patients and their family caregivers. We evaluated BPSD using the Neuropsychiatric Inventory and caregiver burden using the eight-item Japanese version of the Zarit Caregiver Burden Interview. RESULTS: Of the family caregivers, 48.9% showed PHB. Multivariate analysis identified the following association with PHB: caregiver's Zarit Caregiver Burden Interview total score (odds ratio [OR], 1.09 per unit increase; 95% confidence interval [95%CI], 1.02-1.16), and Neuropsychiatric Inventory scores for patient irritability (OR, 1.22 per unit increase; 95%CI, 1.06-1.40), appetite/eating disorders (OR, 1.41 per unit increase; 95%CI = 1.08-1.84) and daughters-in-law caregivers (OR, 0.17, 95%CI, 0.05-0.57). CONCLUSIONS: Specific BPSD symptoms could contribute to the expression of PHB. In addition to decreasing caregiver burden, more intensive treatment and care strategies are required to manage individual symptoms.

We report the autopsy results of a patient with familial dementia who was diagnosed as having frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17) with an R406W mutation in the microtubule-associated protein tau (MAPT) gene. This patient showed Alzheimer's disease (AD)-like clinical manifestations from the age of 59, with reduced ß-amyloid1-42 (Aß42 ) and elevated total and phosphorylated tau levels in the cerebrospinal fluid. He did not present with any apparent parkinsonism throughout the disease course. His autopsy at age 73 showed atrophy and neurodegeneration in many brain regions, particularly in the antero-medial temporal cortex and hippocampus, followed by the frontal lobes, with abundant neurofibrillary tangles. In addition, a diffuse distribution of Aß-positive senile plaques, including many neuritic plaques, was observed and classified as stage C according to the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) criteria. These results suggest that analyzing of the MAPT gene is essential for diagnosing familial dementia, even if amyloid markers such as Aß42 in the cerebrospinal fluid and amyloid imaging are positive, or if neuropathological findings indicate a diagnosis of AD.

BACKGROUND: The Japanese government recently announced the 'Five-Year Plan for Promotion of Measures Against Dementia (Orange Plan)' to promote people with dementia living in their communities. To achieve this, it is imperative that patients hospitalized with behavioural and psychological symptoms of dementia (BPSD) are helped to return to their own homes. The aim of the present study was to identify predictors of home discharge among patients hospitalized for BPSD. METHODS: A single-centre chart review study was conducted on consecutive patients hospitalized from home between April 2006 and March 2011 for the treatment of BPSD. The frequency of discharge back to home was examined in relation to a patient's active behavioural problems and demographics at the time of admission. Diagnoses of dementia were made on the basis of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and consensus guidelines for the clinical and pathologic diagnosis of dementia with Lewy bodies. RESULTS: In all, 391 patients were enrolled in the study. Of these patients, 163 (42%) returned home. Multiple logistic regression analysis identified high Mini-Mental State Examination and Nishimura-style senile activities of daily living scores as significant independent predictors of home discharge. In contrast, living alone and manifestation of aggressiveness at the time of admission were negatively associated with home discharge. CONCLUSIONS: Few patients hospitalized for BPSD are discharged home, and this number is affected by a patient's clinical and demographic characteristics at the time of admission. These findings should be considered in designing and implementing optimal management and care strategies for patients with BPSD.

PURPOSE: To develop an education program for nurses specializing in dementia care, and to investigate its effects. METHODS: An intervention study of nurses was conducted using a quasi-experiment with 3 randomly assigned groups. Participants were 51 nurses from a psychiatric hospital dementia ward, divided into an intervention program group (17 nurses), a knowledge-acquisition-only group (16 nurses), and a usual-care group (18 nurses) as controls. The program group intervention comprised 3 frameworks: motivation for achieving the task, acquisition of professional knowledge required for dementia care, and sharing of successful experiences based on professional knowledge. The knowledge-acquisition-only group received only the acquisition of professional knowledge framework, and the usual-care group received only the usual-care framework. The intervention period was 3 months. RESULTS: Post-intervention, the program group had a significantly greater sense of self-efficacy associated with professional knowledge and significantly greater self-efficacy associated with practice compared with the knowledge-acquisition-only and the usual-care groups. Professional knowledge was acquired by 80% of the program group, compared with 70% of the knowledge-acquisition-only group. A co-occurrence network diagram of the multivariate analysis results produced by text mining of the descriptive data indicated that nurses provided care for symptoms specific to different diseases based on their pathological mechanisms. CONCLUSION: Program implementation led to the acquisition of deeper knowledge and greater self-efficacy by sharing expertise-based practices and successful experiences, compared with desk-based learning in a single workshop lecture, suggesting the program's usefulness in clinical practice.

Autism spectrum disorders (ASD) are characterized by impaired social cognition and communication. In addition to social impairment, individuals with ASD often have intellectual disability. Intelligence is known to influence the phenotypic presentation of ASD. Nevertheless, the relation between intelligence and social reciprocity in people with ASD remains unclear, especially in childhood. To elucidate this relation, we analyzed 56 typically developing children (35 male, 21 female, aged 60-91 months) and 46 children with ASD (35 male, 11 female, aged 60-98 months) from university and affiliated hospitals. Their cognitive function was evaluated using the Kaufman Assessment Battery for Children. Their social cognition was assessed using the Social Responsiveness Scale. We used linear regression models to ascertain whether the associations between intelligence and social cognition of typically developing children and children with ASD are significantly different. Among the children with ASD, scores on the Kaufman Assessment Battery for Children correlated significantly with social cognition, indicating that higher intelligence is associated with better social cognition. For typically developing children, however, no significant correlation was found. One explanation might be that children with ASD fully use general intelligence for successful learning in social cognition, although extensive use of intelligence might not be necessary for TD children. Alternatively, autistic impairment in social cognition can be compensated by intelligence despite a persistent deficit in social cognition. In either case, when using the SRS as a quantitative phenotype measure for ASD, the influence of intelligence must be considered.

BACKGROUND: Depressive mixed state (DMX) has been reported to be one of the most useful clinical markers for bipolar II disorder (BP-II) in the outpatient setting. However, the significance of DMX in emergency psychiatry has not been well studied. METHODS: A chart review study of 139 patients who were hospitalized in an emergency psychiatric ward with an initial diagnosis of major depressive disorder (MDD). RESULTS: In 42 (30.2%) patients, the diagnosis was changed to bipolar disorder after a median observation period of 189 days from hospitalization, and of these, 34 were diagnosed as having BP-II. DMX was observed in 56 (40.3%) patients at the time of hospitalization. Compared with patients who remained in MDD, significantly more patients who later developed bipolar disorder had experienced DMX (59.5% vs. 32.0%, p = 0.0044). In multivariate analysis, DMX was one of the independent predictors of conversion to bipolar disorder (OR 2.45, p = 0.037), and the independent predictors for DMX were chronic depression and atypical features (OR 2.85, p = 0.010; OR 3.67, p = 0.046, respectively). In addition, DMX was significantly more frequently observed at emergency hospitalization than at non-emergency hospitalization (48.6% vs. 29.1%, p = 0.0065). LIMITATIONS: A single reviewer evaluated DMX by chart review. CONCLUSION: DMX is a useful marker of bipolar disorder (mainly BP-II) in the emergency psychiatric setting and is closely related to emergency hospitalization for mood disorders. To confirm these findings, a prospective study that systematically evaluates DMX is needed.

Electroencephalograms of individuals with autism spectrum disorders (ASD) show higher rates of interictal epileptiform discharges (IEDs), which are known to have an inverse association with cognitive function in typically developed (TD) children. Nevertheless, that phenomenon has not been investigated adequately in children with ASD. From university and affiliated hospitals, 163 TD children (84 male, 79 female, aged 32-89 months) and 107 children (85 male, 22 female, aged 36-98 months) with ASD without clinical seizure were recruited. We assessed their cognitive function using the Kaufman Assessment Battery for Children (K-ABC) and recorded 10 min of MEG. Original waveforms were visually inspected. Then a linear regression model was applied to evaluate the association between the IED frequency and level of their cognitive function. Significantly higher rates of IEDs were found in the ASD group than in the TD group. In the TD group, we found significant negative correlation between mental processing scale scores (MPS) and the IED frequency. However, for the ASD group, we found significant positive correlation between MPS scores and the IED frequency. In terms of the achievement scale, correlation was not significant in either group. Although we found a correlative rather than a causal effect, typically developed children with higher IED frequency might better be followed up carefully. Furthermore, for children with ASD without clinical seizure, clinicians might consider IEDs as less harmful than those observed in TD children.
RESUMEN
OBJECTIVE: Most community-based studies have shown a more malignant clinical course for patients with dementia with Lewy bodies (DLB) than Alzheimer's disease (AD). We examined differences in outcomes between patients with DLB and AD hospitalized for the treatment of behavioral and psychological symptoms of dementia. METHOD: A chart review was conducted of patients with either AD or DLB hospitalized in the acute psychogeriatric ward between January 2008 and December 2011 in Kahoku-City, Ishikawa, Japan. Outcome measures were discharge destinations and time to death. A diagnosis of AD was made according to DSM-5 criteria, whereas a diagnosis of DLB was made according to the Consortium on DLB International Workshop criteria for probable DLB. Pharmacologic treatment was optimized under constant monitoring of patients. Cholinesterase inhibitors and yi-gan san were tried prior to antipsychotics in DLB patients. RESULTS: The study cohort consisted of 224 patients with AD and 106 with DLB. After matching for sociodemographic factors and cognitive and physical function, it was found that antipsychotics were less frequently used during hospitalization in patients with DLB than AD (63% vs 82%, respectively, P < .01), whereas cholinesterase inhibitors (88% vs 43%, P < .001) and yi-gan san (35% vs 20%, P < .05) were more frequently used in patients with DLB. There were no significant differences in discharge destinations between the 2 groups. The 5-year cumulative survival rates were similar in the AD and DLB groups (46.4% vs 45.7%, respectively, P = .6225). CONCLUSIONS: Optimization of pharmacologic treatment during hospitalization could reduce the use of antipsychotics and improve the subsequent clinical course in DLB.
RESUMEN
BACKGROUND/AIMS: In Japan, more than 50,000 patients with dementia are housed in psychiatric facilities, a trend precipitated by prolonged hospitalizations. This study aimed to determine predictors for the time to discharge in patients hospitalized for behavioral and psychological symptoms of dementia (BPSD). METHODS: Medical charts of patients admitted to an acute psychogeriatric ward for treatment of BPSD were reviewed. Cox's proportional hazards model was used to evaluate relationships between active behavioral problems and/or demographics at the time of admission, and the time until favorable discharge (FD), defined as discharge to the patient's own home or a care facility. RESULTS: For the 402 study patients included in this study, median time to FD was 101 days. In addition to family and residential factors, multivariate analysis identified higher Mini-Mental State Examination scores as independent clinical predictors for a shorter hospital stay, whereas male gender and combative behavior as the primary reason for hospital admission were predictors for a longer hospital stay. CONCLUSION: Clinical characteristics can be predictive of the time to discharge for patients with BPSD. Earlier interventions and enhanced care strategies may be needed for patients with a lower likelihood of FD.
RESUMEN
OBJECTIVE: To clarify whether hospitalized patients with behavioral and psychological symptoms of dementia (BPSD) show gender differences in manifested symptoms and outcomes. METHOD: A chart review study of patients hospitalized from April 2006 to March 2008 for the treatment of BPSD was conducted. We evaluated the prevalence of symptoms in each of 7 clusters constituting a subscale of the Behavioral Pathology in Alzheimer's Disease Rating Scale and the incidence of favorable discharge, defined as discharge to the patient's own home or care facility. Dementia was diagnosed according to DSM-IV. RESULTS: The study cohort comprised 122 men and 170 women. The men were more likely than the women to present with aggressiveness (78% vs 52%, P < .001) and diurnal rhythm disturbances (89% vs 79%, P < .05) and less likely to present with paranoid, delusional ideation (12% vs 41%, P < .001); hallucination (7% vs 29%, P < .001); affective disturbances (20% vs 40%, P < .001); and anxieties and phobias (15% vs 44%, P < .001). Incidence of favorable discharge was lower in the men (58% vs 77%, P = .001). Even after matching for age, sociodemographic factors, and physical and cognitive functions, the differences in these symptoms persisted, with the exception of diurnal rhythm disturbances. Incidence of favorable discharge was lower in the men (60% vs 77%, P = .0173). CONCLUSION: The data demonstrated gender differences in BPSD and outcomes among hospitalized patients. The findings should be considered when deciding on the optimal management plan for patients with BPSD.

14-3-3 proteins play roles in phosphorylation of tau proteins in neurofibrillary tangles (NFT) in Alzheimer's disease (AD). Tau is phosphorylated at serine (pSer) and threonine (pThr) in NFT, and NFT morphology varies according to phosphorylated sites and tau isoform. The roles of 14-3-3 proteins in NFT morphology remain unknown. This study was performed to examine the relationships between 14 and 3-3 proteins and tau phosphorylation of NFT. NFT were labeled with Gallyas impregnation, tau and 14-3-3 immunohistochemistry in paraffin-embedded hippocampal sections from seven AD and three control brains. Anti-tau antisera included monoclonal antisera that recognize pSer262 (pSer262), pSer422 (pSer422), pSer202/pThr205 (AT8), Thr231 (AT180), three-repeat (RD3) and four-repeat (RD4) tau isoform. Anti-14-3-3 protein isoform antisera included polyclonal antisera to beta, gamma, zeta, epsilon, tau, mu and sigma isoforms and monoclonal antiserum to beta antiserum (H8-beta). NFT density was obtained by counting labeled NFT in cornu ammonis (CA) 1-CA4, subiculum and entorhinal cortex. H8-beta and zeta isoforms were strongly expressed in NFT. Regional densities of NFT positive for pSer262, AT8, AT180, and Gallyas impregnation were similar to RD3-positive NFT density with high densities in CA1 and entorhinal cortex. NFT positive for pSer422 showed a similar regional distribution to RD4-positive NFT with high NFT density in CA2-CA4. H8-beta-positive NFT showed a similar regional distribution to RD3-positive NFT. In contrast, zeta isoform-positive NFT showed no specific distribution. In conclusion, H8-beta isoform is associated with development of 3-repeats NFT but a role of 14-3-3 zeta isoform in NFT could not be specified.
