Abstract
BACKGROUND Increasing levodopa (L-dopa)/dopa decarboxylase inhibitor (DDCI) daily dose or adding a catechol-O-methyltransferase (COMT) inhibitor to levodopa/DDCI therapy are strategies used to manage wearing-off symptoms in Parkinson's disease (PD) patients. OBJECTIVES To evaluate the COMT inhibitor opicapone versus an additional dose of levodopa to treat early wearing-off in PD patients. METHODS ADOPTION was a randomized, parallel-group, open-label, Phase 4 study conducted in Korea. At baseline, eligible patients were randomized (1:1) to opicapone 50 mg (n = 87) or L-dopa 100 mg (n = 81) (added to current L-dopa/DDCI therapy) for 4 weeks. The main efficacy endpoint was change from baseline to end of study in absolute off time. Other endpoints included changes in on time, in Movement Disorder Society-Unified Parkinson's Disease Rating Scale and 8-item PD Questionnaire scores, and the Clinical and Patient Global Impression of Improvement/Change. RESULTS The adjusted mean in absolute off time was significantly greater for opicapone 50 mg than for L-dopa 100 mg (-62.1 vs. -16.7 minutes; P = 0.0015). Opicapone-treated patients also reported a greater reduction in the percentage of off time (P = 0.0015), a greater increase in absolute on time (P = 0.0338) and a greater increase in the percentage of on time (P = 0.0015). There were no significant differences in other secondary endpoints. The L-dopa equivalent daily dose was significantly higher in the opicapone group (750.9 vs. 690.0 mg; P = 0.0247), when a 0.5 conversion factor is applied. CONCLUSIONS Opicapone 50 mg was more effective than an additional 100 mg L-dopa dose at decreasing off time in patients with PD and early wearing-off.

Abstract
Objective The Scales for Outcomes in Parkinson's Disease-Cognition (SCOPA-Cog) was developed to screen for cognition in PD. In this study, we aimed to evaluate the validity and reliability of the Korean version of the SCOPA-cog. Methods We recruited 129 PD patients from 31 clinics with movement disorders in South Korea. The original version of the SCOPA-cognition was translated into Korean using the translation-retranslation method. The test-rest method with an intraclass correlation coefficient (ICC) and Cronbach's alpha coefficient were used to assess reliability. The Spearman's Rank correlation analysis with Montreal Cognitive Assessment-Korean version (MOCA-K) and Korean Mini-Mental State Examination (K-MMSE) were used to assess concurrent validity. Results The Cronbach's alpha coefficient was 0.797, and the ICC was 0.887. Spearman's rank correlation analysis showed a significant correlation with the K-MMSE and MOCA-K scores (r = 0.546 and r = 0.683, respectively). Conclusions Our results demonstrate that K-SCOPA-Cog exhibits good reliability and validity.

Abstract
Although Parkinson's disease (PD) is a representative neurodegenerative disorder and shows characteristic motor impediments, the pathophysiological mechanisms and treatment targets for PD have not yet been clearly identified. Since several tryptophan metabolites produced by gut microbiota could pass the blood-brain barrier and, furthermore, might influence the central nervous system, tryptophan metabolites within the indole, kynurenine, and serotonin metabolic pathways might be the most potent targets for PD development. Furthermore, most metabolites are circulated via the blood, play roles in and/or are metabolized via the host organs, and finally are excreted into the urine. Therefore, profiling the overall tryptophan metabolic pathways in urine samples of patients with PD is important to understanding the pathological mechanisms, finding biomarkers, and discovering therapeutic targets for PD. However, the development of profiling analysis based on tryptophan metabolism pathways in human urine samples is still challenging due to the wide physiological ranges, the varied signal response, and the structural diversity of tryptophan metabolites in complicated urine matrices. In this study, an LC-MS/MS method was developed to profile 21 tryptophan metabolites within the indole, kynurenine, and serotonin metabolic pathways in human urine samples using ion-pairing chromatography and multiple reaction monitoring determination. The developed method was successfully applied to urine samples of PD patients (n = 41) and controls (n = 20). Further, we investigated aberrant metabolites to find biomarkers for PD development and therapeutic targets based on the quantitative results. Unfortunately, most tryptophan metabolites in the urine samples did not present significant differences between control and PD patients, except for indole-3-acetic acid. Nonetheless, indole-3-acetic acid was reported for the first time for its aberrant urinary levels in PD patients and tentatively selected as a potential biomarker for PD. This study provides accurate quantitative results for 21 tryptophan metabolites in biological samples and will be helpful in revealing the pathological mechanisms of PD development, discovering biomarkers for PD, and further providing therapeutic targets for various PD symptoms. In the near future, to further investigate the relationship between gut microbial metabolites and PD, we will employ studies on microbial metabolites using plasma and stool samples from control and PD patients.

Abstract
INTRODUCTION Alpha-synuclein(αSyn) aggregates are definite pathological hallmarks of α-synucleinopathies. Seeding amplification assays (SAAs) have been developed to detect trace amounts of αSyn oligomers in vivo.. Herein, we assessed the diagnostic accuracy of the αSyn-SAAs across biospecimens, diagnostic references, methods, and subtypes. METHODS A systematic literature search yielded 36 eligible studies for a meta-analysis of the sensitivity and specificity of αSyn-SAAs in patients with α-synucleinopathies(n = 2722) and controls(n = 2278). Pooled sensitivities and specificities with 95% confidence intervals (CIs) were calculated using bivariate random-effects models and a meta-regression analysis was performed. RESULTS The summary sensitivity and specificity of αSyn-SAAs positivity for the diagnosis of α-synucleinopathies were 0.88(95% CIs = 0.84-0.91) and 0.95(0.93-0.97), respectively. Two covariates (biospecimen and diagnostic reference) were significant in fitting the meta-regression model (likelihood-ratio test for sensitivity and specificity, p < 0.01, p = 0.01, respectively). Skin αSyn-SAAs exhibited the highest sensitivity 0.92(0.87-0.95), which was not different from that of cerebrospinal fluid (CSF)(0.90(0.86-0.93), p = 0.39). Olfactory mucosa αSyn-SAAs exhibited a lower sensitivity 0.64(0.49-0.76) than those of the other two specimens(p = 0.02, 0.01, compared to CSF and skin, respectively). Application of pathological diagnostic standards were associated with a higher specificity of αSyn-SAAs compared to clinical diagnosis (p < 0.01). The diagnostic sensitivity and specificity of CSF αSyn-SAAs were 0.91(0.87-0.94) and 0.96(0.93-0.98) for Lewy body disease, 0.90(0.79-0.95) and 0.96(0.90-0.98) for prodromal α-synucleinopathies, and 0.63(0.24-0.90) and 0.97(0.93-0.99) for multiple system atrophy. CONCLUSIONS αSyn-SAAs are promising in vivo detectors of abnormal αSyn aggregates and may aid the early diagnosis of α-synucleinopathies.

Abstract
Pain is common in Parkinson’s disease (PD) from its early phase. However, there are no reports of autopsy-proven PD dementia with unusual pain. We report the case of a woman with PD dementia who initially presented with unyielding central neuropathic chest pain and parkinsonism. Diagnostic workup showed no abnormal findings related to her pain. Although her parkinsonism was responsive to dopaminergic medication, her clinical status rapidly deteriorated to dementia with hallucinations and delusions over 2 years. An autopsy was performed following death after 6 years of disease. Pathologic examination revealed diffuse Lewy body pathologies (Braak stage VI), limbic-predominant Alzheimer’s disease pathology, and TAR DNA-binding protein 43 pathologies in the amygdala. The patient was an APOE4 carrier. Multiple pathologies concurrent with the APOE4 allele might be associated with rapid clinical deterioration. Although pathologic substrates for pain remain uncertain, the initial presentation of unusual pain merits further clinicopathological correlation studies.

Abstract
Background Studies of secondary movement disorder (MD) caused by cerebrovascular diseases have primarily focused on post-stroke MD. However, MD can also result from cerebral artery stenosis (CAS) without clinical manifestations of stroke. In this study, we aimed to investigate the clinical characteristics of MD associated with CAS. Materials and Methods A nationwide multicenter retrospective analysis was performed based on the data from patients with CAS-associated MDs from 16 MD specialized clinics in South Korea, available between January 1999 and September 2019. CAS was defined as the >50% luminal stenosis of the major cerebral arteries. The association between MD and CAS was determined by MD specialists using pre-defined clinical criteria. The collected clinical information included baseline demographics, features of MD, characteristics of CAS, treatment, and MD outcomes. Statistical analyses were performed to identify factors associated with the MD outcomes. Results The data from a total of 81 patients with CAS-associated MD were analyzed. The mean age of MD onset was 60.5 ± 19.7 years. Chorea was the most common MD (57%), followed by tremor/limb-shaking, myoclonus, and dystonia. Atherosclerosis was the most common etiology of CAS (78%), with the remaining cases attributed to moyamoya disease (MMD). Relative to patients with atherosclerosis, those with MMD developed MD at a younger age (p < 0.001) and had a more chronic mode of onset (p = 0.001) and less acute ischemic lesion (p = 0.021). Eight patients who underwent surgical treatment for CAS showed positive outcomes. Patients with acute MD onset had a better outcome than those with subacute-to-chronic MD onset (p = 0.008). Conclusions This study highlights the spectrum of CAS-associated with MD across the country. A progressive, age-dependent functional neuronal modulation in the basal ganglia due to CAS may underlie this condition.

Abstract
Movement disorders associated with glial fibrillary acidic protein (GFAP) autoantibodies have rarely been reported as ataxia or tremors. A 32-year-old man with headache and fever, initially diagnosed with viral meningoencephalitis, showed gradual improvement with empirical treatment. Two weeks after the illness, he suddenly developed orofacial, tongue, and neck dyskinesia accompanied by oculomotor abnormalities, which developed into severe generalized choreoballism. Brain magnetic resonance imaging (fluid-attenuated inversion recovery) showed signal hyperintensities in the bilateral globus pallidus interna. The clinical picture suggested an acute inflammatory trigger of secondary autoimmune encephalitis. The autoimmune antibody test was positive for GFAP, with the strongest reactivity in the cerebrospinal fluid (CSF) before treatment and decreased reactivity in serial CSF examinations during immunotherapy. Dyskinesia gradually improved to the extent that it could be controlled with only oral medications. This patient presented with parainfectious GFAP meningoencephalitis with distinctive clinical features and imaging findings.

Abstract
BACKGROUND Tropomyosin-receptor kinase fused gene (TFG) functions as a regulator of intracellular protein packaging and trafficking at the endoplasmic reticulum exit sites. TFG has recently been proposed as a cause of multisystem proteinopathy. OBJECTIVES Here, we describe a Korean family presenting with Parkinson's disease or amyotrophic lateral sclerosis caused by a novel variant of TFG (c.1148 G > A, p.Arg383His). METHODS We collected clinical, genetic, dopamine transporter imaging, nerve conduction, and electromyography data from the seven subjects. To verify the pathogenicity of the R383H variant, we studied cell viability and the abnormal aggregation of α-synuclein and TAR DNA-binding protein 43 (TDP-43) in HeLa cells expressing R383H-TFG. RESULTS The clinical phenotypes of the R383H-TFG mutation varied; of the five family members, one had Parkinson's disease, three had subclinical parkinsonism, and one (the proband) had amyotrophic lateral sclerosis. The individual with multiple system atrophy was the proband's paternal cousin, but the TFG genotype was not confirmed due to unavailability of samples. Our in vitro studies showed that R383H-TFG overexpression impaired cell viability. In cells co-expressing R383H-TFG and α-synuclein, insoluble α-synuclein aggregates increased in concentration and were secreted from the cells and co-localized with R383H-TFG. The levels of cytoplasmic insoluble aggregates of TDP-43 increased in HeLa cells expressing R383H-TFG and co-localized with R383H-TFG. CONCLUSIONS Clinical and in vitro studies have supported the pathogenic role of the novel TFG mutation in α-synucleinopathy and TDP-43 proteinopathy. These findings expand the phenotypic spectrum of TFG and suggest a pivotal role of endoplasmic reticulum dysfunction during neurodegeneration. © 2021 International Parkinson and Movement Disorder Society.

Abstract
Objective
To assess nocturnal hypokinesia using the Korean version of the Nocturnal Hypokinesia Questionnaire (NHQ-K) in Parkinson’s disease (PD) patients across disease stages. Methods
We developed the NHQ-K and performed questionnaire-based interviews with 108 PD patients from three referral hospitals. Clinical associations of nocturnal hypokinesia and its impact on health-related quality of life (HRQoL) were also analyzed. Results
The NHQ-K showed acceptable internal consistency (0.83) and interrater reliability (0.95). Nocturnal hypokinesia significantly affected HRQoL in PD patients at both the early and advanced stages (adjusted p < 0.001). Increased severity of nocturnal hypokinesia was associated with dyskinesias, off-period disability, apathy, and anxious mood in PD patients (adjusted p < 0.01) after controlling for disease severity and medication dose. Conclusion
The NHQ-K is useful for screening nocturnal hypokinesia in PD patients. Given the high impact of nocturnal hypokinesia on HRQoL, comprehensive management of nocturnal disability is needed for PD patients.

Abstract
Background Neurodegenerative disorders are characterized by insidious progression with poorly-delineated long latent period. Antecedent clinical insult could rarely unmask latent neurodegenerative disorders. Here, we report an autopsy-proven case of corticobasal degeneration which was preceded by a lacunar infarction. Case presentation A 58-year-old man presented with acute ataxia associated with a lacunar infarction in the right paramedian pons. His ataxia persisted with additional progressive gait difficulty and left arm clumsiness. Six months later, a follow-up neurological examination showed asymmetrical bradykinesia, apraxia, dystonic posturing, postural instability, and mild ataxia of the left limbs. Cognitive examination revealed frontal executive dysfunction and visuospatial difficulties. Dopamine transporter imaging scan demonstrated bilateral reduced uptakes in mid-to-posterior putamen, more prominent on the right side. Levodopa-unresponsive parkinsonism, asymmetric limb dystonia, and ideomotor apraxia became more conspicuous, while limb ataxia gradually vanished. The patient became unable to walk without assistance after 1 year, and died 4 years after the symptom onset. Autopsy findings showed frontoparietal cortical atrophy, ballooned neurons, and phosphorylated tau-positive astrocytic plaques and neuropil threads with gliosis and neuronal loss, confirming the corticobasal degeneration. Conclusions The case illustrates that precedent clinical events such as stroke might tip a patient with subclinical CBS into overt clinical manifestations.

Abstract
BACKGROUND Gait disturbance gradually worsens as Parkinson's disease (PD) progresses, which significantly affects the quality of life of PD patients. Treadmill-based gait analysis systems can measure gait parameters including the dynamic center-of-pressure (COP) trajectory during ambulation. In this study, we hypothesized that altered dynamic COP changes are new gait characteristics for PD patients. METHODS Dynamic COP parameters and classic spatiotemporal parameters were obtained for each patient using a treadmill-based system at the maximal comfortable treadmill speed (MCTS). We compared dynamic COP parameters between 44 PD patients and 31 controls, correlated these parameters with clinical and spatiotemporal data, and adjusted for age and MCTS to determine whether the parameters were independent from the treadmill speed. We also evaluated characteristics of COP parameters in relation to the more and less affected sides in PD patients. RESULTS During treadmill walking the length of the COP trajectory in the stance phase was decreased, an effect that was more prominent on the more affected side in PD patients. COP parameters related to this change were significantly altered in patients when compared to controls. Asymmetry of the COP trajectories compared between both feet was identified as a significant gait characteristic after adjusting for age and MCTS. The overlaid graphical display of dynamic COP trajectory in PD patients showed "distorted butterfly with asymmetric wing" feature. CONCLUSION Dynamic COP asymmetry provides a new and intuitive way to analyze gait abnormalities of PD patients. Further studies with prospective designs will substantiate the clinical usefulness of this feature of gait.

Abstract
INTRODUCTION In the present study, midbrain atrophy and the pons-to-midbrain area ratio (P/M ratio) were investigated as diagnostic markers for presymptomatic progressive supranuclear palsy-Richardson's syndrome (Pre-PSP-RS). METHODS The present study included 27 patients with probable PSP-RS who underwent brain MRI at least twice before and after the development of clinical symptoms, age- and sex-matched participants with Parkinson's disease (PD, n = 27), and healthy controls (n = 27). The midbrain area, pons area, and P/M ratio of the Pre-PSP-RS, PD, and control subjects were measured using midsagittal images from brain MRI, and the parameters were compared among the groups. RESULTS The midbrain area decreased and the P/M ratio increased significantly in the Pre-PSP-RS patients compared with both the PD and control subjects (midbrain, Pre-PSP-RS vs. PD = 1.01 cm2vs. 1.29 cm2, p < 0.001, Pre-PSP-RS vs. controls = 1.01 cm2vs. 1.29 cm2, p < 0.001; P/M ratio, Pre-PSP-RS vs. PD = 5.27 vs. 4.03, p < 0.001, Pre-PSP-RS vs. controls = 5.27 cm2vs. 4.06 cm2, p < 0.001). The P/M ratio had high sensitivity (vs. PD, 96.3%, vs. control, 88.9%) and specificity (vs. PD, 81.5%, vs. control, 96.3%) in differentiating Pre-PSP-RS patients from PD and control subjects. CONCLUSION Midbrain atrophy precedes the clinical symptoms of PSP-RS and could be a useful diagnostic imaging biomarker for Pre-PSP-RS. Furthermore, this information could play an important role in the development of future treatment strategies.

Abstract
Development of a reliable analytical method of neurochemicals in biological fluids is important to discover potential biomarkers for the diagnosis, treatment and prognosis of neurological disorders. However, neurochemical profiling of biological samples is challenging because of highly different polarities between basic and acidic neurochemicals, low physiological levels, and high matrix interference in biological samples. In this study, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method combined with in situ selective derivatization for comprehensive profiling of 20 neurochemicals in urine was developed for a wide range of neurochemicals. In situ selective derivatization greatly improved the peak capacity on a reversed-phase C18 column and sensitive mass detection in LC-ESI-MS/MS-positive ion mode due to reduction of the distinct physicochemical properties between acidic and basic neurochemicals. The MS/MS spectra of neurochemicals exhibited specific ions, such as losses of amine, methanol, or methyl formate molecules from protonated molecules, enabling selection of appropriate multiple reaction monitoring (MRM) ions for selective and sensitive detection. The developed method was validated in terms of linearity, limit of detection (LOD) and limit of quantification (LOQ), precision, accuracy, and recovery. The correlation coefficients (R2) of calibration curves were above 0.9961. The ranges of LODs and LOQs were 0.1-3.6ng/mL and 0.3-12.0ng/mL, respectively. The overall precision and accuracy were 0.52-16.74% and 82.26-118.17%, respectively. The method was successfully applied to simultaneously profile the metabolic pathways of tyrosine, tryptophan, and glutamate in Parkinson's disease patient urine (PD, n=21) and control urine (n=10). Significant differences (P≤0.01) between two groups in the activity of phenylethanolamine N-methyltransferase (PNMT) and alcohol dehydrogenase (ADH) were observed. In conclusion, this method provides reliable quantification of a wide range of neurochemicals in human urine and would be helpful for finding biomarkers related to specific neuronal diseases.

Abstract
Objective Many patients with Parkinson’s disease (PD) suffer from motor and non-motor symptoms. According to these variable symptoms of PD, patients or caregivers have a poorer quality of life than patients with other neurodegenerative diseases. Since the difficulties are varied for all patients, prioritizing their difficulties differs among all cases. The goal of this study was to investigate the burdens of PD among the caregivers as well as patients and to identify areas requiring aid from the government. Methods We surveyed the awareness and perceptions of PD in patients and caregivers of PD by a face-to-face questionnaire. The questionnaire was divided into three sections: symptoms of PD (part A), desire for policies (part B), and difficulties faced by their caregivers (part C). Part A comprised 8 questions, Part B had 2 questions, and Part C had 3 questions. Results In total, 853 subjects (702 patients and 151 caregivers) were enrolled in this study. The major difficulties experienced by PD patients were physical (67%), psychiatric (60%) and socio-economic (52%). Assessing the physical difficulties, more than half the patients experienced severe difficulties (29% very severe, 39% severe). Psychiatric difficulties were assessed as severe (35%) and very severe (21%) among the patients. Severe difficulties were also experienced socio-economically, at 52% in patients and 49% in caregivers, especially among patients in their fifties (58%) and those with their spouse (65%) as caregivers. The topmost need was the introduction of new technology for treatment of PD (62%), followed by relief of costs for treatment (38%) and a family support system (31%). The majority (91%) of the patients were diagnosed with PD within two years after onset of symptoms. Conclusion We know that the difficulties of PD and the needs for government assistance are different between patients and caregivers. These results emphasize that perceiving the difficulties and needs of patients and caregivers early can help to prevent and ameliorate the burden of disease.

Abstract
Objective Autonomic symptoms are commonly observed in patients with Parkinson’s disease (PD) and often limit the activities of daily living. The Scale for Outcomes in Parkinson’s disease-Autonomic (SCOPA-AUT) was developed to evaluate and quantify autonomic symptoms in PD. The goal of this study was to translate the original SCOPA-AUT, which was written in English, into Korean and to evaluate its reliability and validity for Korean PD patients.
Methods
For the translation, the following processes were performed: forward translation, backward translation, expert review, pretest of the pre-final version and development of the final Korean version of SCOPA-AUT (K-SCOPA-AUT). In total, 127 patients with PD from 31 movement disorder clinics of university-affiliated hospitals in Korea were enrolled in this study. All patients were assessed using the K-SCOPA-AUT and other motor, non-motor, and quality of life scores. Test-retest reliability for the K-SCOPA-AUT was assessed over a time interval of 10−14 days.
Results
The internal consistency and reliability of the K-SCOPA-AUT was 0.727 as measured by the mean Cronbach’s α-coefficient. The test-retest correlation reliability was 0.859 by the Guttman split-half coefficient. The total K-SCOPA-AUT score showed a positive correlation with other non-motor symptoms [the Korean version of non-motor symptom scale (K-NMSS)], activities of daily living (Unified Parkinson’s Disease Rating Scale part II) and quality of life [the Korean version of Parkinson’s Disease Quality of Life 39 (K-PDQ39)].
Conclusion
The K-SCOPA-AUT had good reliability and validity for the assessment of autonomic dysfunction in Korean PD patients. Autonomic symptom severities were associated with many other motor and non-motor impairments and influenced quality of life.

Abstract
Despite the clinical impact of non-motor symptoms (NMS) in Parkinson’s disease (PD), the characteristic NMS in relation to the motor subtypes of PD is not well elucidated. In this study, we enrolled drug-naïve PD patients and compared NMS between PD subtypes. We enrolled 136 drug-naïve, early PD patients and 50 normal controls. All the enrolled PD patients were divided into tremor dominant (TD) and non-tremor dominant (NTD) subtypes. The Non-Motor Symptom Scale and scales for each NMS were completed. We compared NMS and the relationship of NMS with quality of life between normal controls and PD patients, and between the PD subtypes. Comparing with normal controls, PD patients complained of more NMS, especially mood/cognitive symptoms, gastrointestinal symptoms, unexplained pain, weight change, and change in taste or smell. Between the PD subtypes, the NTD subtype showed higher total NMS scale score and sub-score about weight change. Weight change was the characteristic NMS related to NTD subtype even after controlled other variables with logistic regression analysis. Even from the early stage, PD patients suffer from various NMS regardless of dopaminergic medication. Among the various NMS, weight change is the characteristic NMS associated with NTD subtype in PD patients.

Abstract
BACKGROUND The putamen is frequently involved in cases of secondary choreoballism (CB). To date, no study has investigated clinical features of secondary CB such as vascular CB (vCB) and glycemic CB (gCB) in view of putaminal involvement. OBJECTIVES Cases of CB with putaminal lesions from our hospital were identified in hospital records. Historical cases were obtained from the MEDLINE database. Cases of gCB are defined as those with CB, diabetes mellitus and high signal intensities (HSIs) in the putamen on T1 weighted imaging (T1WI). Cases of vCB are identified among those with CB and stroke involving the putamen. RESULTS A total of 284 cases (in-hospital cases, 11 gCB and 3 vCB; historical cases, 225 gCB and 45 vCB) were included after excluding 23 glycemic cases without HSIs on T1WI and 53 cases with non-glycemic etiologies. Persistence of CB was longer than one month in 84 cases (gCB, 36.9%, and vCB, 63.0%). Extra-putaminal lesions occurred more frequently in vCB (71.1%) than gCB (50.7%). Age, cerebrovascular etiology and extra-putaminal lesions were found to be significant predictors for persistence of CB one month after onset. Female gender and extra-putaminal lesions were significant predictors for persistence of CB one year after onset. CONCLUSIONS gCB was the primary common cause of secondary CB involving the putamen. Older age, female gender, vascular etiologies and extensive lesions (putaminal and extra-putaminal) were significant predictors of CB persistence.

Abstract
AbstractBackground:Adult onset tic disorders are usually secondary in origin. We report a case of adult onset tic disorder following carbon monoxide (CO) intoxication with typical magnetic resonance imaging features.Case Report:A 36-year-old woman developed temporarily suppressible patterned movements on her face, neck, and shoulder associated with sensory discomfort after CO poisoning. Magnetic resonance images showed bilateral symmetric cavitary changes in the globus pallidus. Clonazepam relieved much of her symptoms.Conclusion:Our patient developed a mono-symptomatic tic disorder following CO intoxication. This further supports that altered outflow signals from the basal ganglia, especially the globus pallidus, may contribute to the development of tic disorders.

Abstract
Currently there is no neuroprotective or neurorestorative therapy for Parkinson's disease. Here we report that transient receptor potential vanilloid 1 (TRPV1) on astrocytes mediates endogenous production of ciliary neurotrophic factor (CNTF), which prevents the active degeneration of dopamine neurons and leads to behavioural recovery through CNTF receptor alpha (CNTFRα) on nigral dopamine neurons in both the MPP(+)-lesioned or adeno-associated virus α-synuclein rat models of Parkinson's disease. Western blot and immunohistochemical analysis of human post-mortem substantia nigra from Parkinson's disease suggests that this endogenous neuroprotective system (TRPV1 and CNTF on astrocytes, and CNTFRα on dopamine neurons) might have relevance to human Parkinson's disease. Our results suggest that activation of astrocytic TRPV1 activates endogenous neuroprotective machinery in vivo and that it is a novel therapeutic target for the treatment of Parkinson's disease.

Abstract
Both genetic and environmental factors are important in the pathogenesis of Parkinson's disease. As α-synuclein is a major constituent of Lewy bodies, a pathologic hallmark of Parkinson's disease, genetic aspects of α-synuclein is widely studied. However, the influence of dietary factors such as quercetin on α-synuclein was rarely studied. Herein we aimed to study the neuroprotective role of quercetin against various toxins affecting apoptosis, autophagy and aggresome, and the role of quercetin on α-synuclein expression. PC12 cells were pre-treated with quercetin (100, 500, 1,000 μM) and then together with various drugs such as 1-methyl-4-phenylpyridinium (MPP+; a free radical generator), 6-hydroxydopamine (6-OHDA; a free radical generator), ammonium chloride (an autophagy inhibitor), and nocodazole (an aggresome inhibitor). Cell viability was determined using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltertazolium bromide (MTT) assay. Apoptosis was detected by annexin V-fluorescein isothiocyanate and propidium iodide through the use of fluorescence activated cell sorter. α-Synuclein expression was detected by western blot assay and immunohistochemistry. The role of α-synuclein was further studied by knocking out α-synuclein using RNA interference. Cell viability increased at lower concentrations (100 and 500 μM) of quercetin but decreased at higher concentration (1,000 μM). Quercetin exerted neuroprotective effect against MPP+, ammonium chloride and nocodazole at 100 μM. MPP+ induced apoptosis was decreased by 100 μM quercetin. Quercetin treatment increased α-synuclein expression. However, knocking out α-synuclein exerted no significant effect on cell survival. In conclusion, quercetin is neuroprotective against toxic agents via affecting various mechanisms such as apoptosis, autophagy and aggresome. Because α-synuclein expression is increased by quercetin, the role of quercetin as an environmental factor in Parkinson's disease pathogenesis needs further investigation.

Abstract
Magnetic resonance imaging (MRI) is an essential tool for determining the underlying cause of status epilepticus and can exhibit a variety of unpredictable findings. A 28-year-old woman presented with status epilepticus of unknown etiology. She had been recovered from status epilepticus twenty days later, but afterwards developed transient postural instability and cognitive impairment. Initial MRI showed no abnormalities. Follow-up MRI after cessation of status epilepticus demonstrated hyper-intensities lesions in the right claustrum and bilateral external capsular areas on T2 fluid attenuated inversion recovery images. As the external capsule is a route for cholinergic and corticostriatal fibers, cognitive dysfunction and postural instability might be related to these fibers.

Abstract
Although alpha-synuclein is generally thought to have a pathological role in Parkinson's disease, accumulative evidence exists that alpha-synuclein has a neuroprotective effect. The aim of this study was to evaluate the effect of extracellular alpha-synuclein on dopaminergic cell survival. We assessed cell viability using the 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltertazolium bromide (MTT) assay both in undifferentiated SH-SY5Y (SHSY) cells and neuronally-differentiated SH-SY5Y (ndSHSY) cells after 24 hour treatment with monomeric alpha-synuclein at various concentrations (0 [control], 50, 100 nmol/L, 1 μmol/L). To determine whether cell viability assessed by MTT assay was affected by cell proliferation, 5-bromo-2’-deoxyuridine (BrdU) incorporation assay was performed. Level of both Akt and phosphorylated Akt was measured using western blot method in ndSHSY cells with or without 24 hour alpha-synuclein treatment. Cell viability was increased in ndSHSY cells at the nanomolar concentration of alpha-synuclein, but not in SHSY cells. Proportion of BrdU-positive ndSHSY cells was decreased in alpha-synuclein-treated group compared with control group. Level of phosphorylated Akt in alpha-synuclein-treated group was higher compared with the control group. Our study shows that extracellular alpha-synuclein at nanomolar concentration benefits dopaminergic cell survival via Akt pathway.

Abstract
Hemichorea-hemiballism (HCHB) was infrequently related to cortical lesions such as tumor or infarction. Although functional derangement of the basal ganglia (BG) or the thalamus (Th) was suggested, pathomechanism of HCHB secondary to cortical lesions remains uncertain. We recruited the patients with HCHB secondary to cerebrovascular diseases, excluding other causes such as hyperglycemia. All the patients were studied with brain magnetic resonance imaging/angiography (MRI/MRA) and single-photon emission computed tomography (SPECT). Those with only cortical abnormalities in neuroimaging studies were sorted out as the cases of cortical HCHB. Statistical parametric mapping (SPM) analysis of SPECT was performed to investigate the pathomechanism of cortical HCHB. Ten patients (three males and seven females) were included in our study. Six patients had acute BG lesions with SPECT abnormalities, and one had old BG lesions with abnormal SPECT. Three patients were classified as cortical HCHB with lesions only in the frontal and parietal cortices in MRI and SPECT. SPM analysis revealed additional hypoperfusion in frontal areas, leaving BG and Th free of any perfusion abnormalities. Although cortical HCHB was strictly defined by MRI and SPECT, cortical HCHB was not uncommon (30 %). Further analysis showed intertwined networks among the frontal and parietal lobes for cortical HCHB. Cortical dysfunction is important in the pathogenesis of cortical HCHB even without significant involvement of BG and Th.
