    BACKGROUND: People with intellectual disability (ID) without Down syndrome (DS) are presumed to be at higher risk of developing dementia due to their lower baseline cognitive reserve. We aimed to determine the prevalence of dementia in people with ID without DS and to identify risk factors of dementia. METHODS: This was a cross-sectional survey and multicenter study in Japan. Adults with ID without DS residing in the facilities were included. Caregivers of all participants were interviewed by medical specialists, and participants suspected of having cognitive decline were examined directly. ICD-10 criteria for dementia, DC-LD criteria for dementia, and DSM-5 criteria for neurocognitive disorders were used to diagnose dementia. The severity of ID, educational history, and comorbidities were compared by dividing the groups into those with and without dementia. RESULTS: A total of 1831 participants were included; 118/1831 (6.44%) were diagnosed with dementia. The prevalence of dementia for each age group was 8.8%, 60-64 years; 9.0%, 65-69 years; 19.6%, 70-74 years; and 19.4%, 75-79 years. Age, severity of ID, duration of education, hypertension, depression, stroke, and traumatic brain injury were significantly associated with the presence of dementia. CONCLUSIONS: Although the prevalence of dementia in people with ID without DS was found to be higher at a younger age than in the general population, the results of this study suggested that adequate education, prevention of head trauma and stroke, and treatments of hypertension and depression may reduce the risk of dementia. These may be potentially important modifiable risk factors for the prevention of dementia in these people.

    AIM: It was recently reported that theory of mind is disturbed in mild Alzheimer's disease dementia (ADD). Some studies have reported reduced scores of ADD patients on false belief tests, even on first-order false belief tests. However, few studies have pursued the neural substrate of false belief tests in patients with ADD in a real-world setting. METHODS: Sixty-three patients with ADD from outpatient units took the Sally-Anne test and underwent brain single-photon emission computed tomography. Of these patients, 29 answered the Sally-Anne test correctly (successful group) and 34 incorrectly (unsuccessful group). We compared the regional cerebral blood flow between the successful and unsuccessful groups. RESULTS: A comparison of the two groups showed a significantly lower uptake in the bilateral posterior cingulate gyrus in the unsuccessful group than in the successful group. CONCLUSIONS: The posterior cingulate gyrus is known to be particularly activated when individuals remember personal events and infer the mental states of others. We suppose that memory or mentalization in the posterior cingulate gyrus-or both-is essential for patients with ADD to be able to pass the Sally-Anne test.

    BACKGROUND: There are only a few studies of the prevalence of dementia in people with intellectual disability (ID) without Down syndrome (DS), and there is a large difference in the prevalences between reported studies. Moreover, the prevalence of mild cognitive impairment (MCI) in ID has not been reported. We aimed to evaluate the prevalence of dementia in adults of all ages and the prevalence of MCI in people with ID. Furthermore, we tried to clarify the differences depending on the various diagnostic criteria. METHODS: The survey included 493 adults with ID at 28 facilities in Japan. The caregivers answered a questionnaire, and physicians directly examined the participants who were suspected of cognitive decline. Dementia and MCI were diagnosed according to ICD-10, DC-LD, and DSM-5 criteria. RESULTS: The prevalence of dementia was 0.8% for the 45 to 54 years old group, 3.5% for the 55 to 64 years old group, and 13.9% for the 65 to 74 years old group in people with ID without DS. The prevalence of MCI was 3.1% for patients 45 to 54, 3.5% for patients 55 to 64, and 2.8% for patients 65 to 74 with ID without DS. DSM-5 was the most inclusive in diagnosing dementia and MCI in people with ID. CONCLUSIONS: People with ID without DS may develop dementia and MCI at an earlier age and higher rate than the general population. Among the diagnostic criteria, DSM-5 was the most useful for diagnosing their cognitive impairment.

    BACKGROUND: Recently, depression with Lewy body pathology before the appearance of parkinsonism and cognitive dysfunction has been drawing attention. Low cardiac metaiodobenzylguanidine (MIBG) uptake is helpful for early differentiation of Lewy body disease (LBD) from late-onset psychiatric disorders even before parkinsonism or dementia appears. In this study, we used MIBG uptake as a tool in suspected LBD, and evaluated the relationship of MIBG results to clinical characteristics and depressive symptoms. METHODS: Fifty-two elderly inpatients with depression were included in this study. The Hamilton Depression Rating Scale (HDRS) was administered at admission, and 123 I-MIBG cardiac scintigraphy was performed. Of 52 patients, 38 had normal and 14 had reduced MIBG uptake. RESULTS: Correlation analyses of the late phase heart-to-mediastinum (H/M) ratio on the MIBG test and each item of the HDRS revealed that the H/M ratio was significantly correlated with scores of 'agitation', 'anxiety-somatic', and 'retardation' on the HDRS. Mean HDRS composite scores of 'somatic and psychic anxiety (Marcos)' and 'somatic anxiety/somatization factor (Pancheri)' were higher in the low uptake group than in the normal uptake group. CONCLUSION: Elderly patients with depression who manifested an obvious somatic anxiety tend to show low MIBG uptake, and are more likely to have Lewy body pathology.

    BACKGROUND: Early detection of mild cognitive impairment (MCI) and dementia is very important to begin appropriate treatment promptly and to prevent disease exacerbation. We investigated the screening accuracy of the Japanese version of Addenbrooke's Cognitive Examination III (ACE-III) to diagnose MCI and dementia. METHODS: The original ACE-III was translated and adapted to Japanese. It was then administered to a Japanese population. The Hasegawa Dementia Scale-revised (HDS-R) and Mini-mental State Examination (MMSE) were also applied to evaluate cognitive dysfunction. In total, 389 subjects (dementia = 178, MCI = 137, controls = 73) took part in our study. RESULTS: The optimal ACE-III cut-off scores to detect MCI and dementia were 88/89 (sensitivity 0.77, specificity 0.92) and 75/76 (sensitivity 0.82, specificity 0.90), respectively. ACE-III was superior to HDS-R and MMSE in the detection of MCI or dementia. The internal consistency, test-retest reliability, and inter-rater reliability of ACE-III were excellent. CONCLUSIONS: ACE-III is a useful cognitive test to detect MCI and dementia. ACE-III may be widely useful in clinical practice.

    Social cognition has recently been recognized as one of the essential cognitive domains. Some reports suggested that patients with Alzheimer's disease dementia (ADD) presented significant theory of mind deficits even in the mild condition. However, most previous studies included only small numbers of patients with ADD. The present study administered the first-order false belief (Sally-Anne) test to 116 consecutive patients with ADD from the outpatient units of the Memory Clinic and compared the characteristics of the two groups with correct and incorrect answers on the test. Then various clinical characteristics were evaluated. Only 37.1% of patients with ADD correctly answered the Sally-Anne test with the right explanation. Comparison between the two groups of correct and incorrect answers revealed a significant association between the frontal assessment battery score and the result of the Sally-Anne test in the multiple logistic regression analyses. Thus, patients with ADD presented a significant deficit in social cognition even in the mild condition. Frontal dysfunction was thought to be related to the deficits in mild ADD.

    BACKGROUND: It is widely supposed that there is no benefit, including extended survival and decreased rate of pneumonia, in patients with severe dementia receiving enteral tube feeding (TF). However, there have been few studies comparing the frequency of pneumonia before and after TF in severe dementia. METHODS: Nine psychiatric hospitals in Okayama Prefecture participated in this retrospective survey. All inpatients fulfilling the entry criteria were evaluated. All subjects suffered from difficulty in oral intake. Attending physicians thought that the patients could not live without long-term artificial nutrition, and they decided whether or not to make use of long-term artificial nutrition from January 1, 2014 to December 31, 2014. RESULTS: We evaluated 58 patients including 46 with TF and 12 without. The mean age of all patients was 79.6 ± 9.0 years old. Patients with probable Alzheimer's disease (n = 38) formed the biggest group, and those with vascular dementia the second (n = 14). Median survival times were 23 months among patients with TF and two months among patients without TF. The start of TF decreased the frequency of pneumonia and the use of intravenous antibiotics. CONCLUSIONS: TF decreased pneumonia and antibiotic use, even in patients with severe dementia. The results of this study do not necessarily indicate that we should administer TF to patients with severe dementia. We should consider the quality of life of patients carefully before deciding the use or disuse of TF for patients with severe dementia.

    BACKGROUND: Autoimmune hypothalamitis is a very rare neuroendocrine disorder that causes central diabetes insipidus, headache, visual impairment, and sometimes cognitive impairment. Autoimmune hypothalamitis may occur in association with autoimmune hypophysitis, including lymphocytic hypophysitis, or in isolation. It is not known whether autoimmune hypothalamitis and autoimmune hypophysitis are consecutive diseases. CASE PRESENTATION: A 52-year-old woman developed autoimmune hypothalamitis 7 years after developing central diabetes insipidus due to lymphocytic hypophysitis, resulting in severe memory impairment. High-dose intravenous methylprednisolone therapy improved her cognitive function and decreased the size of the lesion. CONCLUSION: This case presented a unique clinical course, with a long period of time between the onset of autoimmune hypopituitaritis and the development of autoimmune hypothalamitis.

    Argyrophilic grain disease (AGD), progressive supranuclear palsy (PSP) and corticobasal degeneration are four-repeat (4R) tauopathies that develop in the presenium or later. Whether these diseases are associated with the occurrence of late-onset psychiatric disorders remains unclear. To facilitate the accumulation of clinicopathological findings regarding this issue, we here present a selected series of 11 cases that clinically developed psychotic disorder (n = 7; age at onset: 41-75 years), depressive disorder (n = 1; 49 years), bipolar disorder (n = 2; 32 and 37 years) and somatoform disorder (n = 1; 88 years), and had at least one pathological hallmark of these tauopathies. The mean age at death was 74.3 years. No case showed dementia, at least in the early stage of the course. Nine cases had AGD. Granular fuzzy astrocytes in the amygdala were noted in all AGD cases and one non-AGD case. Two AGD cases had tufted astrocytes (TAs) in the amygdala but not in the frontal cortex and striatum. Three AGD and two non-AGD cases had TAs in the frontal cortex and/or striatum but not in the amygdala. One AGD case had a small number of astrocytic plaques in the frontal cortex, striatum and globus pallidus. Only one case was diagnosed as atypical PSP according to the NINDS-PSP neuropathological criteria. No case had high-level Alzheimer's disease pathology, Lewy body disease or limbic-predominant age-related TDP-43 encephalopathy. Two cases had mild neuronal loss in the hippocampus and substantia nigra, respectively. Clinicopathological studies focusing especially on early changes of 4R tauopathies, as well as the development of surrogate markers of these diseases, may be necessary for better understanding of the pathogenic backgrounds of late-onset psychiatric disorders.

    AIM: Social cognition encompasses facial expression recognition (FER), theory of mind, and empathy. Although studies examining FER in large numbers of patients with mild cognitive impairment (MCI) or dementia are rare, relative preservation of happiness recognition in dementia was reported in some studies. In this study, we examined performance on FER tests and its relationship to clinical demographics and other cognitive function test scores in patients with cognitive decline. METHODS: The present study administered an FER test and several cognitive tests to outpatients at a memory clinic. The FER test presents four facial expressions (happiness, surprise, anger, and sadness). A total of 187 patients were placed in one of the three groups based on their cognitive status: dementia group (n = 63), MCI group (n = 92), and normal cognition group (n = 32). RESULTS: The total scores on the FER test significantly differed among the three groups (normal > MCI > dementia). In the recognition of happiness and surprise, the dementia group had significantly lower scores than the normal cognition group. There were no significant differences in the recognition of anger and sadness scores among the three groups. The FER scores for happiness and surprise were primarily related to executive function scores, but the FER scores for anger and sadness were primarily related to age. CONCLUSIONS: We note the difference in recognition of causative factors among the four emotions (happiness, surprise, anger, sadness). Our study raises serious doubts about the preservation of happiness recognition hypothesis in dementia based on FER tests.

    Granular/fuzzy astrocytes (GFAs), a subtype of "aging-related tau astrogliopathy," are noted in cases bearing various neurodegenerative diseases. However, the pathogenic significance of GFAs remains unclear. We immunohistochemically examined the frontal cortex, caudate nucleus, putamen and amygdala in 105 cases composed of argyrophilic grain disease cases (AGD, N = 26), and progressive supranuclear palsy (PSP, N = 10), Alzheimer's disease (AD, N = 20) and primary age-related tauopathy cases (PART, N = 18) lacking AGD, as well as 31 cases bearing other various neurodegenerative diseases to clarify (i) the distribution patterns of GFAs in AGD, and PSP, AD and PART lacking AGD, (ii) the impacts of major pathological factors and age on GFA formation and (iii) immunohistochemical features useful to understand the formation process of GFAs. In AGD cases, GFAs consistently occurred in the amygdala (100%), followed by the putamen (69.2%) and caudate nucleus and frontal cortex (57.7%, respectively). In PSP cases without AGD, GFAs were almost consistently noted in all regions examined (90-100%). In AD cases without AGD, GFAs were less frequent, developing preferably in the putamen (35.0%) and caudate nucleus (30.0%). PART cases without AGD had GFAs most frequently in the amygdala (35.3%), being more similar to AGD than to AD cases. Ordered logistic regression analyses using all cases demonstrated that the strongest independent factor of GFA formation in the frontal cortex and striatum was the diagnosis of PSP, while that in the amygdala was AGD. The age was not significantly associated with GFA formation in any region. In GFAs in AGD cases, phosphorylation and conformational change of tau, Gallyas-positive glial threads indistinguishable from those in tufted astrocytes, and the activation of autophagy occurred sequentially. Given these findings, AGD, PSP, AD and PART cases may show distinct distributions of GFAs, which may provide clues to predict the underlying processes of primary tauopathies.

    BACKGROUND: Early detection of mild cognitive impairment (MCI) and dementia is important to promptly start appropriate intervention. However, it is difficult to examine a patient using long and thorough cognitive tests in a general clinical setting. In this study, we aimed to investigate the diagnostic validity of the Addenbrooke's Cognitive Examination - III (ACE-III), Mini-ACE (M-ACE), Montreal Cognitive Assessment (MoCA), Hasegawa Dementia Scale-Revised (HDS-R), and Mini-Mental State Examination (MMSE) to identify MCI and dementia. METHODS: A total of 249 subjects (controls = 50, MCI = 94, dementia = 105) at a memory clinic participated in this study, and took the ACE-III, M-ACE, MoCA, HDS-R, and MMSE. After all examinations had been carried out, a conference was held, and the clinical diagnoses were established. RESULTS: The areas under the curve (AUC) of the ACE-III, M-ACE, MoCA, HDS-R, and MMSE for diagnosing MCI were 0.891, 0.856, 0.831, 0.808, and 0.782. The AUC of the ACE-III was significantly larger than those of the MoCA, HDS-R, and MMSE. The AUCs of the ACE-III, M-ACE, MoCA, HDS-R, and MMSE for diagnosing dementia were 0.930, 0.917, 0.854, 0.871, and 0.856. Thus, the AUCs of the ACE-III and M-ACE were significantly larger than those of the MoCA, HDS-R, and MMSE. CONCLUSION: The ACE-III is a useful cognitive instrument to detect MCI. For distinguishing dementia patients from non-dementia patients, the ACE-III and M-ACE are superior to the MoCA, HDS-R, and MMSE.

    BACKGROUND: Numerous studies focusing on the burden of caregivers of dementia patients have been published. However, there have been few studies focusing on positive affect as an important factor affecting the caregiver burden, and only a few studies comparing the caregiver burden between different dementia diseases have been reported. METHODS: Three hundred and thirty-seven consecutive caregivers of people with dementia participated in this study. The caregiver burden was evaluated by the short version of the Japanese version of the Zarit Burden Interview. RESULTS: Positive affect scores had a significant relationship with the scores of the short version of the Zarit Burden Interview. Caregivers for patients with dementia with Lewy bodies or frontotemporal dementia suffered from a greater burden than those for patients with Alzheimer's disease dementia. CONCLUSIONS: The caregiver burden differed between people caring for patients with different dementia diseases. Positive affect of dementia patients has a significant relationship with caregiver burden, independently from neuropsychiatric symptoms of patients.

    BACKGROUND: In medical practice, a patient's loss of competency is a major obstacle when choosing a treatment and a starting treatment program smoothly. A large number of studies have revealed the lack of medical competency in patients with dementia. However, there have been only a few reports focusing on the capacity of patients with mild cognitive impairment (MCI) to make a medical choice. METHODS: In this study, we evaluated the competency of 40 patients with amnestic MCI (aMCI) and 33 normal subjects to make a medical choice using the MacArthur Competence Assessment Tool-Treatment (MacCAT-T). We compared the judgement of a team conference using the recorded semi-structured interview with the clinical judgement of a chief clinician. RESULTS: A team conference concluded that 12 aMCI patients had no competency, and the clinical judgement, without any special interview, judged that five aMCI patients had no competency. All subjects in the control groups were judged to be competent to consent to treatment by both clinicians and the team conference. CONCLUSIONS: Without supplementary tools such as explanatory documents, not a few patients with aMCI were judged by a team conference to have no competency to consent to therapy even in a relatively simple and easy case. In contrast, clinical physicians tended to evaluate the competency of aMCI patients in a generous manner.

    Neurodegenerative diseases in which tau accumulation plays a cardinal role in the pathogenic process are called tauopathies, and when tau isoforms having four repeats of the microtubule binding sites, four-repeat tau, are selectively accumulated as pathological hallmarks, the term four-repeat tauopathy is used. The major four-repeat tauopathies are progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and argyrophilic grain disease (AGD). Historically, neuronal cytopathologies, e.g., neurofibrillary tangles and ballooned neurons, were emphasized as characteristic lesions in PSP and CBD. Now, however, astrocytic tau pathologies, i.e., tufted astrocytes (TAs) and astrocytic plaques (APs), are considered to be highly disease-specific lesions. Although granular/fuzzy astrocytes (GFAs) frequently develop in the limbic system in AGD cases, the specificity is not conclusive yet. Some AGD cases have a few TAs, and to a lesser frequency, a few APs in the frontal cortex and subcortical nuclei. The number of astrocytic tau pathologies including TAs and GFAs increases with the progression of AGD. In this paper, histopathological features of astrocytic tau pathologies in PSP, CBD, and AGD are first reviewed. Then, recent findings regarding the coexistence of these tauopathies are summarized from a viewpoint of astrocytic tau pathologies. Further biochemical and pathological studies focusing tau-positive astrocytic lesions may be useful to increase understanding of the pathological process in four-repeat tauopathies and to develop novel therapeutic strategies for patients with these diseases.

    The clinical features in cases that have mutations in the microtubule-associated protein tau gene but lack prominent behavioral changes remain unclear. Here, we describe detailed clinical and pathological features of a case carrying the P301L tau mutation that showed only apathy until the middle stage of the course. The mother of this case was suspected to have mild cognitive decline at age 46. However, before she was fully examined, she had a subarachnoid hemorrhage at age 49 and died at age 53. An autopsy was not done. The proband of this pedigree, a 60-year-old right-handed Japanese man at the time of death, began to make mistakes at work at the age of 51 years. Until age 54, he showed only mild apathy with bradykinesia. Insight was well spared. Parkinsonism and echolalia developed at age 55, and pyramidal signs and oral tendency at age 57. Personality change, disinhibition, stereotypy, or semantic memory impairment was not found throughout the course. The final neurological diagnosis was unspecified dementia. Pathological examination demonstrated numerous round four-repeat tau-positive three-repeat tau-negative or perinuclear ring-like neuronal cytoplasmic inclusions with many ballooned neurons in the frontal and temporal cortices and hippocampus. Genetic analysis using frozen brain tissue demonstrated a P301L tau mutation. Among 31 previously reported cases bearing the P301L tau mutation for which the data regarding initial symptoms are available, one clinical case showed only apathy with depression in the early stage. Given these findings, clinicians should be aware that a clinical course characterized only by apathy for several years, which can be misdiagnosed as a psychiatric disorder, is one of the clinical presentations associated with P301L tau mutation.

    BACKGROUND: Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disease. Common first symptoms are dementia, cerebellar ataxia, visual disturbance, and psychiatric symptoms. Seizure as the first symptom of CJD is a very rare finding. CASE PRESENTATION: We experienced an elderly woman who presented initially with status epilepticus following repeated partial seizures in the course of Alzheimer disease (AD) dementia. Anti-convulsive therapy had no effect. Autopsy revealed definite CJD with AD pathology. COCLUSIONS: This is the first reported CJD case presenting with status epilepticus in the course of AD dementia.

    Argyrophilic grain disease (AGD) is a common four-repeat tauopathy in elderly people. While dementia is a major clinical picture of AGD, recent studies support the possibility that AGD may be a pathological base in some patients with mild cognitive impairment, late-onset psychosis, bipolar disorder and depression. AGD often coexists with various other degenerative changes. The frequency of AGD in progressive supranuclear palsy (PSP) cases was reported to range from 18.8% to 80%. The frequency of AGD in corticobasal degeneration (CBD) cases tends to be higher than that in PSP cases, ranging from 41.2% to 100%. Conversely, in our previous study of the frequencies of mild PSP and CBD pathologies in AGD cases, five of 20 AGD cases (25%) had a few Gallyas-positive tufted astrocytes, six cases (30%) had a few granular/fuzzy astrocytes, and one case (5.0%) had a few Gallyas-positive astrocytic plaques in the putamen, caudate nucleus and/or superior frontal gyrus. Both Gallyas-positive tufted astrocytes and Gallyas-negative tau-positive granular/fuzzy astrocytes preferentially developed in the putamen, caudate nucleus and superior frontal cortex in AGD cases, being consistent with the predilection sites of Gallyas-positive tufted astrocytes in PSP cases. Further, in AGD cases, the quantities of Gallyas-positive tufted astrocytes, overall tau-positive astrocytes, and tau-positive neurons in the subcortical nuclei and superior frontal cortex were significantly correlated with Saito AGD stage, respectively. The frequency of AGD in AD cases was reported to reach up to 25% when using four-repeat tau immunohistochemistry. Pretangles are essential pathologies in AGD; however, the Braak stage of three-repeat tau-positive NFTs, which may indicate mild AD pathology or primary age-related tauopathy, was not correlated with Saito AGD stage. Clinicians should be aware of the possibility that coexisting AGD may impact clinical and radiological features in cases of other degenerative diseases.

    Objective: Among many cognitive function deficits, memory impairment is an initial and cardinal symptom in Alzheimer disease (AD). In most cases, verbal and visual memory scores correlate highly, but in some cases the deficit of verbal or visual memory is very different from that of the other memory. In this study, we examined the neural substrates of verbal and visual memory in patients with AD. Methods: One hundred eighty-eight consecutive patients with AD were recruited from outpatient units. Verbal and visual memory scores were evaluated using the Wechsler Memory Scale - revised. The patients underwent brain SPECT with 99mTc-ethylcysteinate dimer. Results: After removing the effects of age, sex, education, and Mini-Mental State Examination scores, correlation analysis showed a significant correlation of verbal memory scores to regional cerebral blood flow (rCBF) in the bilateral cingulate gyrus and left precuneus. Similarly, a significant correlation of visual memory scores to rCBF was found in the right precuneus and right cingulate gyrus. Conclusion: The posterior medial cortices (PMC) are very important areas in episodic memory among patients with mild AD. Verbal memory is more closely related to the both sides of the PMC, while visual memory is more closely related to the right PMC. (c) 2018 The Author(s) Published by S. Karger AG, Basel

    It is very rare that cases of Pick's disease, a representative three-repeat (3R) tauopathy, also have significant four-repeat (4R) tau accumulation. Here, we report a Pick's disease case that clinically showed behavioral variant frontotemporal dementia without motor disturbance during the course, and pathologically had 3R tau-positive Pick bodies as well as numerous 4R tau-positive neuronal cytoplasmic inclusions (NCIs). Abundant 3R tau-positive 4R tau-negative spherical or horseshoe-shaped Pick bodies were found in the frontotemporal cortex, limbic region, striatum and pontine nucleus. On the other hand, many 4R tau-positive, 3R tau-negative, Gallyas-negative dot-, rod- or intertwined skein-like NCIs were found mainly in the subthalamic nucleus, pontine nucleus, inferior olivary nucleus and cerebellar dentate nucleus. Tufted astrocytes, astrocytic plaques, argyrophilic grains or globular glial inclusions were absent. Double-labeling immunofluorescence demonstrated that 3R tau was hardly accumulated in 4R tau-positive inclusions. On tau immunoblotting, while 60 and 64 kDa bands were demonstrated in the frontal cortex, 60, 64 and 68 kDa bands, as well as the 33 kDa tau fragments that are reported to be characteristic of progressive supranuclear palsy brains, were found in the basal ganglia and cerebellum. No mutation was identified in the tau gene. The present case suggests that, although probably rare, some Pick's disease cases have non-negligible 4R tau pathology in the subcortical nuclei, and that such 4R tau pathology can affect the evaluation of the distribution of AT8-positive tau pathology in Pick's disease cases.

    これまで、世界中で数多くの認知機能検査が作成されてきた。しかし、海外で作成された認知機能検査を和訳して日本に持ち込んでも、そのまま臨床で使用することはできず、日本語版として標準化する手順が必要になる。筆者らのグループでは、海外で開発された認知機能検査の日本語版を作成し、その信頼性と妥当性を検証する研究を行ってきた。本稿では、2019年に日本語版の検証を終えたAddenbrooke's Cognitive Examination-III(ACE-III)について述べながら、海外の認知機能検査を日本に標準化する際の要点を述べた。(著者抄録)

    広島市民病院機構広島市民病院に2015年1月1日から3月31日に、がんを主病名として入院した患者を対象に、当院でのせん妄ケアプログラムのがん患者に対する施行状況を調査し、せん妄リスクの早期からの把握や看護師による評価と精神科コンサルテーションとの関連などについて検討した。電子カルテより後方視的に調査した。対象期間中の入院がん患者973例中963例(99.0%)にせん妄ケアプログラムが適用された。せん妄リスクアセスメントの結果として、せん妄リスクなし708例(73.5%)、せん妄リスク192例(19.9%)、せん妄ハイリスク56例(5.6%)、アルコール離脱リスク7例(0.7%)であった。約1/4にせん妄リスクが存在し、早期に予防介入が行われていたことが分かった。精神科コンサルテーション診断がせん妄であった症例の約半数で、せん妄ケアプログラムでの看護師による評価ではせん妄が見落とされ、特に低活動型や混合型の見落としが多かったことが明らかになった。
