Abstract
INTRODUCTION A higher levodopa dose is a risk factor for motor complications in Parkinson's disease (PD). Istradefylline (IST) is used as adjunctive treatment to levodopa in PD patients with off episodes, but its impact on levodopa dose titration remains unclear. The objective of this study was to investigate the effect of IST on levodopa dose escalation in PD patients with wearing-off. METHODS This was a multicenter, open-label, randomized, parallel-group controlled study (ISTRA ADJUST PD) in which PD patients experiencing wearing-off (n = 114) who were receiving levodopa 300-400 mg/day were randomized to receive IST or no IST (control). Levodopa dose was escalated according to clinical severity. The primary endpoint was cumulative additional levodopa dose, and secondary endpoints were changes in symptom rating scales, motor activity determined by a wearable device, and safety outcomes. RESULTS The cumulative additional levodopa dose throughout 37 weeks and dose increase over 36 weeks were significantly lower in the IST group than in the control group (both p < 0.0001). The Movement Disorder Society Unified Parkinson's Disease Rating Scale Part I and device-evaluated motor activities improved significantly from baseline to 36 weeks in the IST group only (all p < 0.05). Other secondary endpoints were comparable between the groups. Adverse drug reactions (ADRs) occurred in 28.8% and 13.2% of patients in the IST and control groups, respectively, with no serious ADRs in either group. CONCLUSION IST treatment reduced levodopa dose escalation in PD patients, resulting in less cumulative levodopa use. Adjunctive IST may improve motor function more objectively than increased levodopa dose in patients with PD. TRIAL REGISTRATION Japan Registry of Clinical Trials: jRCTs031180248.

Abstract
Corticobasal syndrome (CBS) is characterized by symptoms related to the asymmetric involvement of the cerebral cortex and basal ganglia. However, early detection of asymmetric imaging abnormalities can be challenging. Previous studies reported asymmetric 18F-THK5351 PET abnormalities in CBS patients, but the sensitivity for detecting such abnormalities in larger patient samples, including early-stage cases, remains unclear. Patients clinically diagnosed with CBS were recruited. All patients displayed asymmetric symptoms in the cerebral cortex and basal ganglia. Asymmetric THK5351 PET abnormalities were determined through visual assessment. Brain MRI, perfusion SPECT, and dopamine transporter (DAT) SPECT results were retrospectively reviewed. The 15 patients had a median age of 72 years (59-86 years) and a disease duration of 2 years (0.5-7 years). Four patients met the probable and 11 met the possible CBS criteria according to Armstrong criteria at the time of PET examination. All patients, including early-stage cases, exhibited asymmetric tracer uptake contralateral to their symptom-dominant side in the cerebral cortex/subcortical white matter and striatum (100%). The sensitivity for detecting asymmetric imaging abnormalities contralateral to the symptom-dominant side was 86.7% for brain MRI, 81.8% for perfusion SPECT, and 90% for DAT SPECT. White matter volume reduction was observed in the subcortical region of the precentral gyrus with increased THK5351 uptake, occurring significantly more frequently than gray matter volume reduction. THK5351 PET may be a sensitive imaging technique for detecting asymmetric CBS pathologies, including those in early stages.

Abstract
BACKGROUND AND OBJECTIVES CSF tau phosphorylated at threonine 181 (p-tau181) is a widely used biomarker for Alzheimer disease (AD) and has recently been regarded to reflect β-amyloid and/or p-tau deposition in the AD brain. Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disease characterized by intranuclear inclusions in neurons, glial cells, and other somatic cells. Symptoms include dementia, neuropathy, and others. CSF biomarkers were not reported. The objective of this study was to investigate whether CSF biomarkers including p-tau181 are altered in patients with NIID. METHODS This was a retrospective observational study. CSF concentrations of p-tau181, total tau, amyloid-beta 1-42 (Aβ42), monoamine metabolites homovanillic acid (HVA), and 5-hydroxyindole acetic acid (5-HIAA) were compared between 12 patients with NIID, 120 patients with Alzheimer clinical syndrome biologically confirmed based on CSF biomarker profiles, and patients clinically diagnosed with other neurocognitive disorders (dementia with Lewy bodies [DLB], 24; frontotemporal dementia [FTD], 13; progressive supranuclear palsy [PSP], 21; and corticobasal syndrome [CBS], 13). Amyloid PET using Pittsburgh compound B (PiB) was performed in 6 patients with NIID. RESULTS The mean age of patients with NIID, AD, DLB, FTD, PSP, and CBS was 71.3, 74.6, 76.8, 70.2, 75.5, and 71.9 years, respectively. CSF p-tau181 was significantly higher in NIID (72.7 ± 24.8 pg/mL) compared with DLB, PSP, and CBS and was comparable between NIID and AD. CSF p-tau181 was above the cutoff value (50.0 pg/mL) in 11 of 12 patients with NIID (91.7%). Within these patients, only 2 patients showed decreased CSF Aβ42, and these patients showed negative or mild local accumulation in PiB PET, respectively. PiB PET scans were negative in the remaining 4 patients tested. The proportion of patients with increased CSF p-tau181 and normal Aβ42 (A-T+) was significantly higher in NIID (75%) compared with DLB, PSP, and CBS (4.2%, 4.8%, and 7.7%, respectively). CSF HVA and 5-HIAA concentrations were significantly higher in patients with NIID compared with disease controls. DISCUSSION CSF p-tau181 was increased in patients with NIID without amyloid accumulation. Although the deposition of p-tau has not been reported in NIID brains, the molecular mechanism of tau phosphorylation or secretion of p-tau may be altered in NIID.

Abstract
Abstract
Pathogenic variants in genes that cause dilated (DCM) and arrhythmogenic cardiomyopathies (ACM) convey high risks for the development of heart failure (HF) through unknown mechanisms. Using single nucleus RNA sequencing (snRNAseq), we characterized the transcriptome of 880,000 nuclei from 18 control and 61 failing, non-ischemic human hearts with pathogenic variants in DCM and ACM genes or idiopathic disease. We performed genotype-stratified analyses of the ventricular cell lineages and transcriptional states. The resultant DCM and ACM ventricular cell atlas demonstrated distinct right and left ventricular responses, highlighting genotype-associated pathways, intercellular interactions, and differential gene expression at single cell resolution. Together these data illuminate both shared and distinct cellular and molecular architectures of human HF and suggest novel candidate therapeutic targets.

Abstract
OBJECTIVES Concentrations of soluble amyloid precursor proteins-α (sAPPα) and -β (sAPPβ) in cerebrospinal fluid (CSF) may reflect the neuropathology of Alzheimer's disease (AD). We previously reported that the concentrations of both sAPPα and sAPPβ were significantly higher in patients with mild cognitive impairment (MCI) due to AD (MCI-AD) than in control subjects without cognitive impairment. The present study analyzed whether these sAPPs are useful in the differential diagnosis of MCI. METHODS A modified and sensitive method was used to analyze concentrations of sAPPα and sAPPβ in CSF of patients with MCI-AD (n = 30) and MCI due to other causes (MCI-others) (n = 24). Phosphorylated tau (p-tau) and amyloid β-protein 42 (Aβ42) were also analyzed using standard methods. RESULTS CSF concentrations of sAPPα and sAPPβ were significantly higher in the MCI-AD than in the MCI-others group (p < 0.001). Furthermore, concentrations of both sAPPα and sAPPβ were highly correlated with the concentration of p-tau, consistent with our previous report. CONCLUSIONS Measurement of both sAPPs in CSF using sensitive methods can be helpful in the precise differential diagnosis of patients with MCI.

Abstract
INTRODUCTION Alzheimer's disease (AD) is one of the most common causes of dementia. Pathogenic variants in the presenilin 1 (PSEN1) gene are the most frequent cause of early-onset AD. Medications for patients with AD bearing PSEN1 mutation (PSEN1-AD) are limited to symptomatic therapies and no established radical treatments are available. Induced pluripotent stem cell (iPSC)-based drug repurposing identified bromocriptine as a therapeutic candidate for PSEN1-AD. In this study, we used an enrichment strategy with iPSCs to select the study population, and we will investigate the safety and efficacy of an orally administered dose of bromocriptine in patients with PSEN1-AD. METHODS AND ANALYSIS This is a multicentre, randomised, placebo-controlled trial. AD patients with PSEN1 mutations and a Mini Mental State Examination-Japanese score of ≤25 will be randomly assigned, at a 2:1 ratio, to the trial drug or placebo group (≥4 patients in TW-012R and ≥2 patients in placebo). This clinical trial consists of a screening period, double-blind phase (9 months) and extension phase (3 months). The double-blind phase for evaluating the efficacy and safety is composed of the low-dose maintenance period (10 mg/day), high-dose maintenance period (22.5 mg/day) and tapering period of the trial drug. Additionally, there is an open-labelled active drug extension period for evaluating long-term safety. Primary outcomes are safety and efficacy in cognitive and psychological function. Also, exploratory investigations for the efficacy of bromocriptine by neurological scores and biomarkers will be conducted. ETHICS AND DISSEMINATION The proposed trial is conducted according to the Declaration of Helsinki, and was approved by the Institutional Review Board (K070). The study results are expected to be disseminated at international or national conferences and published in international journals following the peer-review process. TRIAL REGISTRATION NUMBER jRCT2041200008, NCT04413344.

Abstract
Background: Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) are often misdiagnosed with each other because of similar symptoms including progressive memory loss. The metabolic network topology that describes inter-regional metabolic connections can be generated using fluorodeoxyglucose positron emission tomography (FDG-PET) data with the graph-theoretical method. We hypothesized that different metabolic connectivity underlies the symptoms of AD patients, DLB patients, and cognitively normal (CN) individuals. Objective: This study aimed to generate metabolic connectivity using FDG-PET data and assess the network topology to differentiate AD patients, DLB patients, and CN individuals. Methods: This study included 45 AD patients, 18 DLB patients, and 142 CN controls. We analyzed FDG-PET data using the graph-theoretical method and generated the network topology in AD patients, DLB patients, and CN individuals. We statistically assessed the topology with global and nodal parameters. Results: The whole metabolic network was preserved in CN; however, diffusely decreased connection was found in AD and partially but more deeply decreased connection was observed in DLB. The metabolic topology revealed that the right posterior cingulate and the left transverse temporal gyrus were significantly different between AD and DLB. Conclusion: The present findings indicate that metabolic connectivity decreased in both AD and DLB, compared with CN. DLB was characterized restricted but deeper stereotyped network disruption compared with AD. The right posterior cingulate and the left transverse temporal gyrus are significant regions in the metabolic connectivity for differentiating AD from DLB.

Abstract
Voxel-based morphometry (VBM) analysis of nuclear Magnetic Resonance Imaging (MRI) data allows the identification of medial temporal lobe (MTL) atrophy and is widely used to assist the diagnosis of Alzheimer's disease (AD). However, its reliability in the clinical environment has not yet been confirmed. To determine the credibility of VBM, amyloid positron emission tomography (PET) and VBM studies were compared retrospectively. Patients who underwent Pittsburgh Compound B (PiB) PET were retrospectively recruited. Ninety-seven patients were found to be amyloid negative and 116 were amyloid positive. MTL atrophy in the PiB positive group, as quantified by thin sliced 3D MRI and VBM software, was significantly more severe (p =0.0039) than in the PiB negative group. However, data histogram showed a vast overlap between the two groups. The area under the ROC curve (AUC) was 0.646. MMSE scores of patients in the amyloid negative and positive groups were also significantly different (p = 0.0028), and the AUC was 0.672. Thus, MTL atrophy could not reliably differentiate between amyloid positive and negative patients in a clinical setting, possibly due to the wide array of dementia-type diseases that exist other than AD.

Abstract
A previous study reported that a massive cerebral infarct in the territory of the middle cerebral artery (MCA) may be associated with development of neurofibrillary tangles (NFTs) in the ipsilateral basal nucleus of Meynert (BNM). We analyzed 19 cases of an MCA territory infarct and 12 with a putaminal hemorrhage (mean age 82.5 years; female/male ratio 8/23; mean time from stroke onset to autopsy 4182 days). In both groups, 74–100% had a significantly higher rate of phosphorylated tau immunoreactive or Gallyas Braak silver stain-positive neurons on the BNM-affected side than on the BNM-unaffected side. These NFTs were immunoreactive for anti-RD3 and anti-RD4 antibodies, and a triple-band pattern was observed by immunoblot analysis with anti-tau antibody. Most NFTs might be formed within the 5–10 years after stroke onset. There were significantly more TAR DNA-binding protein 43 (TDP43) immunoreactive structures on the BNM-affected side than on the BNM-unaffected side. We showed that many NFTs with TDP43-immunoreactive structures were observed in the ipsilateral BNM associated with a massive cerebral infarct in the MCA territory or a putaminal hemorrhage.

Abstract
An 86-year-old woman presented with generalized chorea in the face and extremities, which gradually progressed for two weeks. Cranial CT revealed a chronic subdural hematoma (CSDH) that covered the left parietal lobe. Discontinuation of amantadine did not improve the chorea. The hematoma was evacuated and the chorea completely subsided in a week. The pathogenesis leading to chorea in CSDH remains unclear. A unilateral hematoma presenting with generalized chorea similar to the present patient and two others with unilateral CSDH causing ipsilateral hemichorea have been reported. The rarity of these movement disorders due to CSDH indicates that these patients had a preclinical dysfunction within neuronal networks interconnecting basal ganglia the cerebral cortex. Our findings confirmed that CSDH could cause chorea, and further neuroimaging to evaluate cerebrovascular disease, taking a detailed family history and obtaining information about current medications might reveal factors likely to precipitate the development of chorea.

Abstract
Background Because soluble (or secreted) amyloid precursor protein-β (sAPPβ) and -α (sAPPα) possibly reflect pathological features of Alzheimer’s disease (AD), they are potential biomarker candidates for dementia disorders, including AD and mild cognitive impairment (MCI) due to AD (MCI-AD). However, controversial results have been reported regarding their alterations in the cerebrospinal fluid (CSF) of AD and MCI-AD patients. In this study, we re-assessed the utility of sAPPα and sAPPβ in CSF as diagnostic biomarkers of dementia disorders. Methods We used a modified and sensitive detection method to analyze sAPPs levels in CSF in four groups of patients: AD (N = 33), MCI-AD (N = 17), non-AD dementia (N = 27), and disease controls (N = 19). Phosphorylated tau (p-tau), total tau, and Aβ42 were also analyzed using standard methods. Results A strong correlation was observed between sAPPα and sAPPβ, consistent with previous reports. Both sAPPα and sAPPβ were highly correlated with p-tau and total tau, suggesting that sAPPs possibly reflect neuropathological changes in the brain. Levels of sAPPα were significantly higher in MCI-AD cases compared with non-AD and disease control cases, and those of sAPPβ were also significantly higher in MCI-AD and AD cases relative to other cases. A logistic regression analysis indicated that sAPPα and sAPPβ have good discriminative power for the diagnosis of MCI-AD. Conclusions Our findings collectively suggest that both sAPPs are pathologically relevant and potentially useful biomarkers for early and accurate diagnosis of dementia disorders. We also suggest that careful measurement is important in assessing the diagnostic utility of CSF sAPPs.

Abstract
Neuronal intranuclear hyaline inclusion disease (NIHID) is a neurodegenerative disorder characterized by the presence of eosinophilic nuclear inclusions (NIs) in diverse cell lines in systemic organs. Adult-onset NIHID typically manifests with dementia associated with leukoencephalopathy. The detection of NIs in skin biopsies is useful for an antemortem diagnosis. A previous analysis suggested that NIs in NIHID originated from nuclear bodies (NBs), an important nuclear domain related to the ubiquitin-p62-mediated protein degradation system. In this study, we analyzed skin samples from 5 NIHID and 5 control cases immunohistochemically and electron microscopically. In the control cases, small but significant amounts of ubiquitin- and p62-positive intranuclear structures were found. These structures were consistently colocalized with promyelocytic leukemia protein (PML), an essential component of NBs, in particular when activated. The p62- and PML-positive structures were more frequently found in NIHID cases. Activated NBs, having a core and a shell, were observed by electron microscopy in control but not in NIHID cases. Instead, immature and mature filamentous NIs were found only in the NIHID cases. Our results indicate that NBs could not be normally activated in the NIHID, and an abnormal alteration of NBs might be related to the pathogenesis of NIHID.

Abstract
BACKGROUND Atherosclerotic changes in the cerebral arteries may differ with era of birth. Herein, we analyzed the chronological changes of intracranial atherosclerosis in consecutive autopsy cases. METHODS A total of 7260 autopsy cases from 1972 to 2014 were analyzed. Severity of atherosclerosis was classified using a semi-quantitative scale of pathologic observation of each artery after formalin fixation: 0 = no stenosis; .5 = fatty streaks but no stenosis; 1 = <50% stenosis; 2 = 50%-90% stenosis; 3 = ≥90% stenosis. The bilateral vertebral, anterior, middle, and posterior cerebral arteries and the basilar artery were scored. The sum of each individual was defined and compared by age at death, sex, and era of birth. RESULTS The atherosclerosis score increased with age at death, as follows: age in the 50s, 0 [0-2]; 60s, 3 [.5-7]; 70s, 5 [2-9.5]; 80s, 6.5 [3.5-11.5]; 90s, 7.75 [4-12]; and 100s, 8 [5.5-13.5] (median value [interquartile range], P< .0001). The percentage of cases with a score of 2 or 3 in each artery also increased with age (P< .0001). Atherosclerosis score was higher in men than women in their 60s at death, and was higher in women than men in their 80s and 90s at death. In each age at death group (from 60s to 100s), the score declined with later year of birth (P < .05). CONCLUSIONS Intracranial atherosclerosis advances with age and is more severe in subjects born earlier.

Abstract
Introduction:
It has not been analyzed whether atherosclerotic changes in the major cerebral arteries differ with age or with era of birth.
Hypothesis:
To examine our hypothesis that such changes would vary with age at death and era of birth, we studied chronological changes in intracranial artery atherosclerosis in consecutive autopsy cases.
Methods:
We analyzed 7307 autopsy cases of our brain bank from 1972 to 2014. Severity of atherosclerosis was classified on the following semi-quantitative scale based on pathological observation of each artery after formalin fixation: 0 = no stenosis; 0.5 = fatty streaks but no stenosis; 1 = less than 50% stenosis; 2 = 50% to 90% stenosis; 3 = 90% or more stenosis. We scored the cerebral arteries (anterior, middle, and posterior) and vertebral arteries bilaterally and the basilar artery. Then we summed the scores in each patient and defined the sum as the atherosclerosis score. We compared atherosclerosis scores by age at death and era of birth.
Results:
Atherosclerosis scores increased with age at death, as follows: age 50s, 1.9 ± 3.8; 60s, 4.6 ± 5.2; 70s, 6.1 ± 5.3; 80s, 7.6 ± 5.4; 90s, 8.2 ± 5.3; and 100s, 9.2 ± 5.3 (mean ± SD, P < 0.0001). The percentage of cases with a score of 2 or 3 in each artery also increased with age (P < 0.0001). Interestingly, in each age group (from the 60s to 90s) at the time of death, the score declined as the birth year became later (Figure. P < 0.0001, box plots for each group showing atherosclerosis score).
Conclusions:
Our analysis from a brain bank cohort showed that intracranial artery atherosclerosis 1) advanced with age, and 2) was more severe in subjects born earlier.

Abstract
¹¹C-Pittsburgh compound B (PiB) uptake in PET images is frequently used to analyze β amyloid (Aβ) deposition in living individuals, but its correlation with histologically determined Aβ has not been examined. Six individuals with dementia underwent PiB-PET imaging, and their brains were analyzed neuropathologically (mean interval between imaging and death: 816 days; PiB positive:negative, 3:3; male:female, 3:3; mean age: 84.0 years). PiB uptake (reported as standardized uptake value ratio [SUVR]) was analyzed in 11 cortical regions and 10 subcortical grey matter areas and compared with the Aβ load (% area [the percentage of total area positive for Aβ] and number of neuritic plaques) seen with immunohistochemical staining with an anti-Aβ 11-28 antibody. Two PiB-positive subjects had abundant neuritic plaques and were diagnosed with Alzheimer’s disease (AD). SUVR and % area were strongly correlated in the cortical regions of these subjects (subject 1: r = 0.65, p = 0.03; subject 2: r = 0.80, p = 0.003). The other PiBpositive subject (subject 3) showed focal PiB uptake. In subject 3 and the 3 PiB-negative subjects (subjects 4-6), there was no correlation between regional SUVR and % area or neuritic plaques. PiB uptake was not correlated with Aβ deposition in subcortical regions. High PiB positivity in the cerebral cortex suggests the presence of substantial Aβ deposition and neuritic plaques associated with the pathologic changes of AD. Our results suggest that high cortical SUVR is a reliable marker of AD. Subcortical PiB positivity must be interpreted more carefully.

Abstract
A 62-year-old woman presented at our hospital with a headache, cognitive decline, and fever that had persisted for 3 months. On admission, fever, headache, and mild cognitive dysfunction were all clearly evident, suggesting chronic meningoencephalitis. Laboratory examination showed mild neutrophilia as well as an increase in her erythrocyte sedimentation rate and serum C-reactive protein levels. MRI showed multiple small hyperintense lesions on T2 weighted image and diffusion weighted image (DWI) in the cerebral cortex and white matter. Contrast-enhanced T1 weighted image showed the abnormal pial enhancement along the cerebral sulci. Systemic evaluations for infectious organisms, autoantibodies, and malignant tumors were all negative. Her fever and neurological symptoms continued. As a result of worsening MRI findings, a brain biopsy was carried out. Neuropathological analysis revealed neutrophilic infiltration in the subarachnoid space and multinucleated giant cells. However, there was no vasculitis on the histological sections. This pathological finding was reminiscent of rheumatoid meningitis despite articular findings of rheumatoid arthritis, as well as rheumatoid factor (RF) and anti-CCP antibody tests being negative. After oral steroid therapy, her fever and inflammatory reactions by laboratory test diminished and her cognitive function improved remarkably.

Abstract
We report the case of an individual with corticobasal syndrome (CBS), hypopituitarism due to a post-traumatic leptomeningeal cyst, and Hashimoto's disease. A 71-year-old woman was admitted to our hospital because of cognitive dysfunction and bradykinesia. Following a primary diagnosis of hypopituitarism and hypothyroidism, she was given hormone replacement therapy, and her clinical symptoms appeared to improve. However, some cognitive impairment and extrapyramidal symptoms remained. The results of careful neurological examinations, as well as magnetic resonance, single-photon emission computed tomography, and positron emission tomography images, suggested a diagnosis of CBS-CBD (corticobasal degeneration). Because parkinsonism and cognitive impairment can be caused by endocrinopathy, it was initially difficult to reach the complete diagnosis that included CBS. Thus, it is important to understand that complicated neurological presentations can be caused by several different disorders.

Abstract
In Lewy body disease, Lewy pathology (LP: the accumulation of α-synuclein in neuronal perikarya and processes as Lewy bodies and Lewy neurites and dots, respectively) is observed in the central and peripheral nervous systems. Previous autopsy or biopsy studies of individuals with Lewy body diseases (LBDs) indicated that LP could be observed in the peripheral nerves of the gastrointestinal (GI) systems. The aim of this study is to clarify whether examination of GI and biliary surgical specimens would be useful for diagnosing LBD. We analyzed eight patients diagnosed clinically with LBD and with medical histories of GI or biliary surgery at our hospital. LP was identified by using α-synuclein immunohistochemistry in GI and biliary surgical specimens obtained before, at or after the clinical onset of LBD. LP was frequently observed in Auerbach's plexus, Meissner's plexus and the subserosal nerve fascicles within the GI and biliary surgical specimens. LP was observed in the specimens obtained 7 years before the onset of LBD. Our approach does not require any invasive procedures for patients. The immunohistochemical analysis of anti- α-synuclein antibody to archival GI or biliary surgical specimens from patients with clinically suspected LBD may contribute to clinical diagnosis of LBD.

Abstract
Purpose Diagnosing corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP) is often difficult due to the wide variety of symptoms and overlaps in the similar clinical courses and neurological findings. The purpose of this study was to evaluate the utility of white matter (WM) atrophy for the diagnosis of patients with clinically diagnosed CBD (corticobasal syndrome, CBS) and PSP (Richardson’s syndrome, RS). Methods We randomly divided the 3D T1-weighted MR images of 18 CBS patients, 33 RS patients, and 32 age-matched controls into two groups. We obtained segmented WM images in the first group using Voxel-based specific regional analysis system for Alzheimer’s disease (VSRAD) based on statistical parametric mapping (SPM) 8 plus diffeomorphic anatomical registration through exponentiated Lie algebra. A target volume of interest (VOI) for disease-specific atrophy was subsequently determined in this group using SPM8 group analyses of WM atrophy between patients groups and controls. We then evaluated the utility of these VOIs for diagnosing CBS and RS patients in the second group. Z score values in these VOIs were used as the determinant in receiver operating characteristic (ROC) analyses. Results Specific target VOIs were determined in the bilateral frontal subcortical WM for CBS and in the midbrain tegmentum for RS. In ROC analyses, the target VOIs of CBS and RS compared to those of controls exhibited an area under curve (AUC) of 0.99 and 0.84, respectively, which indicated an adequate diagnostic power. The VOI of CBS revealed a higher AUC than that of RS for differentiating between CBS and RS (AUC, 0.75 vs 0.53). Conclusions Bilateral frontal WM volume reduction demonstrated a higher power for differentiating CBS from RS. This VOI analysis is useful for clinically diagnosing CBS and RS. ・We evaluate the utility of white matter (WM) atrophy for the diagnosis of patients with corticobasal syndrome (CBS) and Richardson’s syndrome (RS). ・We obtained segmented WM images using Voxel-based specific regional analysis system for Alzheimer’ s disease based on statistical parametric mapping 8 plus diffeomorphic anatomical registration through exponentiated Lie algebra. ・The most significant areas of atrophy observed in CBS patients compared to the controls were in the bilateral frontal subcortical WM. ・The most significant areas of atrophy observed in RS patients compared to the controls were in the midbrain. ・The volume of interest analysis using bilateral frontal WM volume reduction demonstrated a higher power for differentiating CBS from RS.

Abstract
OBJECTIVES Sporadic cerebral amyloid angiopathy (CAA) is common cause of cerebrovascular disorders that predominantly affect elderly patients. When symptomatic, cortical-subcortical intracerebral haemorrhage (ICH) in the elderly is the most well-known manifestation of CAA. Furthermore, the clinical presentation varies from a sudden neurological deficit to seizures, transient symptoms and acute progressive cognitive decline. Despite its clinical importance, this multifaceted nature poses a diagnostic challenge for radiologists. The aims of this study were to expound the characteristics of neuroimaging modalities, which cover a wide spectrum of CAA-related imaging findings, and to review the various abnormal findings for which CAA could be responsible. CONCLUSIONS Radiologically, in addition to typical ICH, CAA leads to various types of abnormal findings, including microbleed, subarachnoid haemorrhage, superficial siderosis, microinfarction, reversible oedema, and irreversible leukoaraiosis. Taking into consideration the clinical importance of CAA-related disorders such as haemorrhagic risks and treatable oedema, it is necessary for radiologists to understand the wide spectrum of CAA-related imaging findings. TEACHING POINTS • To describe the characteristics of imaging modalities and findings of CAA-related disorders. • MRI, especially gradient echo sequences, provides the useful information of CAA-related haemosiderin depositions. • To understand the wide spectrum of CAA-related neuroimaging and clinical features is important.

Abstract
Aberrant protein aggregation is closely linked to the molecular pathogeneses of most neurodegenerative diseases. The major components of pathological aggregates have been characterized in various neurodegenerative diseases; for example, amyloid β-protein and phosphorylated tau in Alzheimer's disease, α-synuclein in Parkinson's disease, SOD1 or TDP-43 in amyotrophic lateral sclerosis, and huntingtin in Huntington's disease. These misfolded protein aggregates play a vital role in disease initiation and progression, and they have recently been shown to have prion-like spreading or seeded aggregation properties. Immunotherapy with specific monoclonal antibodies is a promising approach to clear misfolded protein aggregates and treat various neurodegenerative diseases; it is planned for use in clinical trials in the near future.

Abstract
BACKGROUND AND PURPOSE Stem cell transplantation therapy is a promising option for treatment of severe ischaemic heart disease. Dimethyl sulphoxide (DMSO) differentiates P19CL6 embryonic carcinoma cells into cardiomyocyte-like cells, but with low differentiation capacity. To improve the degree of this differentiation, we have assessed several derivatives of the differentiation-inducing factor-1 (DIF-1), originally found in the cellular slime mould Dictyostelium discoideum, on P19CL6 cells. EXPERIMENTAL APPROACH P19CL6 cells were cultured with each derivative and 1% DMSO for up to 16 days. Differentiation was assessed by measuring the number of beating and non-beating aggregates, and the expression of genes relevant to cardiac tissue. The mechanism of action was investigated using a T-type Ca(2+) channel blocker. KEY RESULTS Of all the DIF-1 derivatives tested only Br-DIF-1 showed any effects on cardiomyocyte differentiation. In the presence of 1% DMSO, Br-DIF-1 (0.3-3 µM) significantly and dose-dependently increased the number of spontaneously beating aggregates compared with 1% DMSO alone, by day 16. Expression of mRNA for T-type calcium channels was significantly increased by Br-DIF-1 + 1% DMSO compared with 1% DMSO alone. Mibefradil (a T-type Ca(2+) channel blocker; 100 nM) and a small interfering RNA for the T-type Ca(2+) channel both significantly decreased the beating rate of aggregates induced by Br-DIF-1 + 1% DMSO. CONCLUSIONS AND IMPLICATIONS Br-DIF-1 accelerated the differentiation, induced by 1% DMSO, of P19CL6 cells into spontaneously beating cardiomyocyte-like cells, partly by enhancing the expression of the T-type Ca(2+) channel gene.

Abstract
OBJECTIVES To evaluate the association between cerebrospinal fluid (CSF) homovanillic acid (HVA) concentrations and nigrostriatal dopaminergic function assessed by positron emission tomography (PET) imaging with carbon-11-labeled 2beta-carbomethoxy-3beta-(4-fluorophenyl)-tropane ((11)C-CFT), which can measure the dopamine transporter (DAT) density, in Parkinson's disease (PD). METHODS (11)C-CFT PET scans and CSF examinations were performed on 21 patients with PD, and six patients with non-parkinsonian syndromes (NPS) as a control group. RESULTS In the PD group, CSF HVA concentrations were significantly correlated with the striatal uptake of (11)C-CFT (r = 0.76, P < 0.01). However, in the NPS group, two indices were within the normal range. CONCLUSIONS In PD, CSF HVA concentrations correlate with nigrostriatal dopaminergic function. Therefore, CSF HVA concentrations may be an additional surrogate marker for estimating the remaining nigrostriatal dopaminergic function in case that DAT imaging is unavailable.
