Abstract
Restless legs syndrome (RLS) is one of the most common neurological disorders. It describes an irresistible urge to move the legs, mostly manifested in the evening and at night, which can lead to severe sleep disturbance. As part of the European Brain Council (EBC)-led Value-of-Treatment project, this study aimed at capturing the socioeconomic impact of RLS related to the inadequate diagnosis and treatment across different European healthcare settings. The economic burden of RLS was estimated using the published EBC framework of analysis in three separate European Union healthcare systems (France, Germany, and Italy). The RLS care pathway was mapped to identify the unmet needs of patients. Based on specific patient stories, the economic impact of correctly diagnosing RLS and changing between inadequate and target treatment was calculated using appropriate scenario analysis. RLS proved to be a significant personal and social burden, when epidemiological data, high prevalence of RLS, and its need for treatment are combined. By looking at the savings emerging from the provision of optimal care management (timely and correct diagnosis, evidence-based therapy, avoidance of therapy-related complications such as augmentation), the authors foresee substantial economic savings with the achievement of adequate diagnosis and treatment of RLS. Education about RLS is urgently needed for all subspecialties involved in RLS patient care as well as the general public. Equally important, the search for new causal treatment strategies should be intensified to reduce suffering and substantial societal cost.

Abstract
BACKGROUND Parkinson's disease (PD) is a chronic progressive neurological disorder with a high psychosocial and economic burden. As part of the European Brain Council (EBC)-led Value of Treatment project, this study aimed to capture the economic benefit of timely, adequate, and adherence to PD treatment. METHODS The EBC Value of Treatment Initiative combined different stakeholders to identify unmet needs in the patients' journey according to Rotterdam methodology. The economic evaluation focused on three major topics identified as major gaps: start of treatment; best treatment for advanced disease; and adherence to treatment. Two separate healthcare systems (Germany and the UK) were chosen. Cost-effectiveness was determined by using decision-analytical modelling approaches. Effectiveness was expressed as quality-adjusted life-years (QALYs) gained and incremental cost-effectiveness ratio (ICER). RESULTS Treatment intervention in PD was found to be cost-effective regardless of the initial health state of the patient receiving the treatment. Cost savings were between -€1000 and -€5400 with 0.10 QALY gain and -€1800 and -€7600 with 0.10 QALY gain for Germany and the UK, respectively. Treatment remains cost-effective within the National Institute for Health and Care Excellence thresholds. Availability of adequate treatment to more patients was also found to be cost-effective, with an ICER of €15,000-€32,600 across country settings. Achieving the target adherence to treatment would generate cost-savings of €239,000-€576,000 (Germany) and €917,000-€2,980.000 (UK) for every 1,000 patients treated adequately. CONCLUSIONS The analyses confirmed that timely, adequate, and adherence to PD treatment will not only improve care of the patients but is also cost-effective across healthcare systems. Further studies with a distinct identification of gaps in care are necessary to develop better and affordable care.

Abstract
REM sleep behavior disorder (RBD) is strongly associated with development of Parkinson’s Disease and other α-synuclein-related disorders. Dopamine transporter (DAT) binding deficit predicts conversion to α-synuclein-related disorders in individuals with RBD. In turn, identifying which individuals with RBD have the highest likelihood of having abnormal DAT binding would be useful. The objective of this analysis was to examine if there are basic clinical predictors of DAT deficit in RBD. Participants referred for inclusion in the RBD cohort of the Parkinson Progression Markers Initiative were included. Assessments at the screening visit including DAT SPECT imaging, physical examination, cognitive function screen, and questionnaire-based non-motor assessment. The group with DAT binding deficit (n = 49) was compared to those without (n = 26). There were no significant differences in demographic or clinical features between the two groups. When recruiting RBD cohorts enriched for high risk of neurodegenerative disorders, our data support the need for objective biomarker assessments. The clinical characteristics of patients with rapid eye movement sleep behavior disorder (RBD) are not associated with reduced dopamine transporter binding, an established imaging biomarker of Parkinson’s Disease (PD). Because around 80 percent of patients with RBD develop PD, there is great hope that research on these patients will help uncover early signs of the disease and guide the development of neuroprotective therapies. Lana Chahine at The University of Pittsburgh, USA, and colleagues in the Parkinson Progression Markers Initiative (PPMI) Sleep Working Group analyzed the clinical features of 75 individuals with RBD. They found no significant differences in demographic features or in motor and non-motor symptoms between RBD patients with dopamine transporter binding deficit and those without. These findings highlight the need to assess dopamine transporter binding to determine the future risk of PD.

Abstract
Parkinson's disease (PD) is a multisystem disorder with a plethora of symptoms affecting the quality of life of patients in the home environment. Due to the rapid development of wearable technique in the health and fitness sector, an increasing number of such wearable devices are available to complement diagnostic strategies of PD symptoms not only in the clinical but also in the home environment. This development has clear advantages over clinical evaluation, as the latter is relatively subjective, time-consuming and costly, and provides only a snapshot of the condition. First results about the use of such technology for the assessment of PD symptoms (including bradykinesia, dyskinesia, tremor, daily activity and sleep behavior) in the home environment are promising. They suggest that these techniques can provide complementary information about the symptoms of PD patients, and have the potential to be included in future diagnostic workup concepts of routine care in PD. The use of such technique provides also the opportunity to more actively include patients into medical decision-making processes.

Abstract
The GSI (General Symptom Index) of the Symptom Checklist 90 R (SCL 90 R) (as a global indicator of the severity of psychiatric symptoms) of 27% of the spasmodic torticollis (ST) sample fell outside the 95% range of the normal control group (two standard deviations). Patients with a higher GSI were younger, more functionally disabled and subject to higher psychosocial stress due to the illness. The highest scores were reached on the subscales of somatization, interpersonal sensitivity and depression. On the depression scale, 23% of the patients' scores were abnormal. This scale correlated significantly with the neurological signs, particularly the TSUI-index and laterocollis. A statistically significant correlation also existed between psychiatric morbidity and a family history of mental disorder. More than 50% of the patients reported that stressful life events had triggered their illness. In order of frequency, a death came first, followed by marital strife, changes in employment and family arguments. The data suggest that psychopathology in ST should generally be considered as a result of a variety of interacting factors, biological, psychological and social.

Abstract
OBJECTIVES We aimed to provide a consensus statement by the International Rapid Eye Movement Sleep Behavior Disorder Study Group (IRBD-SG) on devising controlled active treatment studies in rapid eye movement sleep behavior disorder (RBD) and devising studies of neuroprotection against Parkinson disease (PD) and related neurodegeneration in RBD. METHODS The consensus statement was generated during the fourth IRBD-SG symposium in Marburg, Germany in 2011. The IRBD-SG identified essential methodologic components for a randomized trial in RBD, including potential screening and diagnostic criteria, inclusion and exclusion criteria, primary and secondary outcomes for symptomatic therapy trials (particularly for melatonin and clonazepam), and potential primary and secondary outcomes for eventual trials with disease-modifying and neuroprotective agents. The latter trials are considered urgent, given the high conversion rate from idiopathic RBD (iRBD) to Parkinsonian disorders (i.e., PD, dementia with Lewy bodies [DLB], multiple system atrophy [MSA]). RESULTS Six inclusion criteria were identified for symptomatic therapy and neuroprotective trials: (1) diagnosis of RBD needs to satisfy the International Classification of Sleep Disorders, second edition, (ICSD-2) criteria; (2) minimum frequency of RBD episodes should preferably be ⩾2 times weekly to allow for assessment of change; (3) if the PD-RBD target population is included, it should be in the early stages of PD defined as Hoehn and Yahr stages 1-3 in Off (untreated); (4) iRBD patients with soft neurologic dysfunction and with operational criteria established by the consensus of study investigators; (5) patients with mild cognitive impairment (MCI); and (6) optimally treated comorbid OSA. Twenty-four exclusion criteria were identified. The primary outcome measure for RBD treatment trials was determined to be the Clinical Global Impression (CGI) efficacy index, consisting of a four-point scale with a four-point side-effect scale. Assessment of video-polysomnographic (vPSG) changes holds promise but is costly and needs further elaboration. Secondary outcome measures include sleep diaries; sleepiness scales; PD sleep scale 2 (PDSS-2); serial motor examinations; cognitive indices; mood and anxiety indices; assessment of frequency of falls, gait impairment, and apathy; fatigue severity scale; and actigraphy and customized bed alarm systems. Consensus also was established for evaluating the clinical and vPSG aspects of RBD. End points for neuroprotective trials in RBD, taking lessons from research in PD, should be focused on the ultimate goal of determining the performance of disease-modifying agents. To date no compound with convincing evidence of disease-modifying or neuroprotective efficacy has been identified in PD. Nevertheless, iRBD patients are considered ideal candidates for neuroprotective studies. CONCLUSIONS The IRBD-SG provides an important platform for developing multinational collaborative studies on RBD such as on environmental risk factors for iRBD, as recently reported in a peer-reviewed journal article, and on controlled active treatment studies for symptomatic and neuroprotective therapy that emerged during the 2011 consensus conference in Marburg, Germany, as described in our report.

Abstract
BACKGROUND A Task Force was convened by the EFNS/MDS-ES Scientist Panel on Parkinson's disease (PD) and other movement disorders to systemically review relevant publications on the diagnosis of PD. METHODS Following the EFNS instruction for the preparation of neurological diagnostic guidelines, recommendation levels have been generated for diagnostic criteria and investigations. RESULTS For the clinical diagnosis, we recommend the use of the Queen Square Brain Bank criteria (Level B). Genetic testing for specific mutations is recommended on an individual basis (Level B), taking into account specific features (i.e. family history and age of onset). We recommend olfactory testing to differentiate PD from other parkinsonian disorders including recessive forms (Level A). Screening for pre-motor PD with olfactory testing requires additional tests due to limited specificity. Drug challenge tests are not recommended for the diagnosis in de novo parkinsonian patients. There is an insufficient evidence to support their role in the differential diagnosis between PD and other parkinsonian syndromes. We recommend an assessment of cognition and a screening for REM sleep behaviour disorder, psychotic manifestations and severe depression in the initial evaluation of suspected PD cases (Level A). Transcranial sonography is recommended for the differentiation of PD from atypical and secondary parkinsonian disorders (Level A), for the early diagnosis of PD and in the detection of subjects at risk for PD (Level A), although the technique is so far not universally used and requires some expertise. Because specificity of TCS for the development of PD is limited, TCS should be used in conjunction with other screening tests. Conventional magnetic resonance imaging and diffusion-weighted imaging at 1.5 T are recommended as neuroimaging tools that can support a diagnosis of multiple system atrophy (MSA) or progressive supranuclear palsy versus PD on the basis of regional atrophy and signal change as well as diffusivity patterns (Level A). DaTscan SPECT is registered in Europe and the United States for the differential diagnosis between degenerative parkinsonisms and essential tremor (Level A). More specifically, DaTscan is indicated in the presence of significant diagnostic uncertainty such as parkinsonism associated with neuroleptic exposure and atypical tremor manifestations such as isolated unilateral postural tremor. Studies of [(123) I]MIBG/SPECT cardiac uptake may be used to identify patients with PD versus controls and MSA patients (Level A). All other SPECT imaging studies do not fulfil registration standards and cannot be recommended for routine clinical use. At the moment, no conclusion can be drawn as to diagnostic efficacy of autonomic function tests, neurophysiological tests and positron emission tomography imaging in PD. CONCLUSIONS The diagnosis of PD is still largely based on the correct identification of its clinical features. Selected investigations (genetic, olfactory, and neuroimaging studies) have an ancillary role in confirming the diagnosis, and some of them could be possibly used in the near future to identify subjects in a pre-symptomatic phase of the disease.

Abstract
OBJECTIVE Idiopathic REM sleep behavior disorder is a parasomnia characterized by dream enactment and is commonly a prediagnostic sign of parkinsonism and dementia. Since risk factors have not been defined, we initiated a multicenter case-control study to assess environmental and lifestyle risk factors for REM sleep behavior disorder. METHODS Cases were patients with idiopathic REM sleep behavior disorder who were free of dementia and parkinsonism, recruited from 13 International REM Sleep Behavior Disorder Study Group centers. Controls were matched according to age and sex. Potential environmental and lifestyle risk factors were assessed via standardized questionnaire. Unconditional logistic regression adjusting for age, sex, and center was conducted to investigate the environmental factors. RESULTS A total of 694 participants (347 patients, 347 controls) were recruited. Among cases, mean age was 67.7 ± 9.6 years and 81.0% were male. Cases were more likely to smoke (ever smokers = 64.0% vs 55.5%, adjusted odds ratio [OR] = 1.43, p = 0.028). Caffeine and alcohol use were not different between cases and controls. Cases were more likely to report previous head injury (19.3% vs 12.7%, OR = 1.59, p = 0.037). Cases had fewer years of formal schooling (11.1 ± 4.4 years vs 12.7 ± 4.3, p < 0.001), and were more likely to report having worked as farmers (19.7% vs 12.5% OR = 1.67, p = 0.022) with borderline increase in welding (17.8% vs 12.1%, OR = 1.53, p = 0.063). Previous occupational pesticide exposure was more prevalent in cases than controls (11.8% vs 6.1%, OR = 2.16, p = 0.008). CONCLUSIONS Smoking, head injury, pesticide exposure, and farming are potential risk factors for idiopathic REM sleep behavior disorder.

Abstract
UNLABELLED It is unknown, how frequently Parkinson's disease (PD) is complicated by dementia, depression and other neuropsychiatric conditions. An epidemiologic characterisation of the situation in specialised neurologic settings is lacking. The Geman Study on the Epidemiology of Parkinson's Disease with Dementia (GEPAD) isa national representative epidemiological study of n=1449 PD patients in n=315 office-based neurological settings, designed to estimate the prevalence of dementia, depression and other neuropsychiatric conditions in patients with PD of all stages by using standardized clinical assessments. RESULTS 28.6% met DSM-IV criteria for dementia. 33.6% met criteria for depression and 61% additionally had other clinically significant psychopathological syndromes. Only 29.4% had no neuropsychiatric conditions. GEPAD reveals for the first time comprehensively that the neuropsychiatric burden of PD patients in all stages and even early stages is considerable, posing challenging questions for research and clinical management.

Abstract
Imaging of the brain structure with transcranial ultrasound has become an important tool for the diagnosis and differential diagnosis of Parkinson's Disease. In up to 90 % of parkinsonian patients abnormal echogenity of the substantia nigra could be demonstrated. Particularly in the early diagnosis in subjects with only very mild extrapyramidal features and in the differential diagnosis to other neurodegenerative disorders with parkinsonian features, such as the parkinsonian variant of multisystematrophy (MSA-P) and progressive supranuclear paralysis (PSP) ultrasound has a high diagnostic yield. Because of a prevalence of about 10 % in the normal population, the evidence of an abnormal echogenity of the substantia nigra has to be interpreted carefully in the context of a clinical examination. Although there are a number of studies indicating that in some of these subjects a vulnerability of the nigrostriatal system can be found, the meaning of an abnormal echogenicity of the substantia nigra in the healthy population needs to be further elucidated in already ongoing research projects.

Abstract
Tauopathies with parkinsonism represent a spectrum of disease entities unified by the pathologic accumulation of hyperphosphorylated tau protein fragments within the central nervous system. These pathologic characteristics suggest shared pathogenetic pathways and possible molecular targets for disease-modifying therapeutic interventions. Natural history studies, for instance, in progressive supranuclear palsy, frontotemporal dementia with parkinsonism linked to chromosome 17, corticobasal degeneration, and Niemann-Pick disease type C as well as in amyotrophic lateral sclerosis/Parkinson-dementia complex permit clinical characterization of the disease phenotypes and are crucial to the development and validation of biological markers for differential diagnostics and disease monitoring, for example, by use of neuroimaging or proteomic approaches. The wide pathologic and clinical spectrum of the tauopathies with parkinsonism is reviewed in this article, and perspectives on future advances in the understanding of the pathogenesis are given, together with potential therapeutic strategies.

Abstract
The aim of this study was to describe the present involvement of neurologists in dementia management in European countries. Data were obtained from a questionnaire that members of The European Federation of Neurological Societies Scientific Panel on Dementia responded to. Information was obtained from 25 countries in Europe. A progressive decrease in the teaching activity from medical school to board-certified neurologists was reported. Teaching of medical students in dementia is obligatory in most countries, whereas there is no formal obligatory education in dementia after graduation from medical school. Further, in only half of the countries that responded to the questionnaire, obligatory courses in dementia are part of the training in neurology. Except for one country, the post-graduate training programs of board-certified neurologists do not include dementia as an obligatory topic. In only 10 of 25 countries, guidelines for neurologists on dementia evaluation have been published in local language. It is recommended to include obligatory teaching and training in dementia in the catalogue of minimum requirements for specialist training in neurology and this teaching should also be part of the ongoing update of certified neurologists.

Abstract
The aim of the study was to provide evidence-based recommendations for the management of early (uncomplicated) Parkinson's disease (PD), based on a review of the literature. Uncomplicated PD refers to patients suffering from the classical motor syndrome of PD only, without treatment-induced motor complications and without neuropsychiatric or autonomic problems. MEDLINE, Cochrane Library and International Network of Agencies for Health Technology Assessment (INAHTA) database literature searches were conducted. National guidelines were requested from all European Federation of Neurological Societies (EFNS) societies. Non-European guidelines were searched for using MEDLINE. Part I of the guidelines deals with prevention of disease progression, symptomatic treatment of motor features (parkinsonism), and prevention of motor and neuropsychiatric complications of therapy. For each topic, a list of therapeutic interventions is provided, including classification of evidence. Following this, recommendations for management are given, alongside ratings of efficacy. Classifications of evidence and ratings of efficacy are made according to EFNS guidance. In cases where there is insufficient scientific evidence, a consensus statement (good practice point) is made.

Abstract
Introduction. The European Multiple System Atrophy-Study Group (EMSA-SG) is an academic network comprising 23 centers across Europe and Israel that has constituted itself already in January 1999. This international forum of established experts under the guidance of the University Hospital of Innsbruck as coordinating center is supported by the 5th framework program of the European Union since March 2001 (QLK6-CT-2000-00661). Objectives. Primary goals of the network include (1) a central Registry for European multiple system atrophy (MSA) patients, (2) a decentralized DNA Bank, (3) the development and validation of the novel Unified MSA Rating Scale (UMSARS), (4) the conduction of a Natural History Study (NHS), and (5) the planning or implementation of interventional therapeutic trials. Methods. The EMSA-SG Registry is a computerized data bank localized at the coordinating centre in Innsbruck collecting diagnostic and therapeutic data of MSA patients. Blood samples of patients and controls are recruited into the DNA Bank. The UMSARS is a novel specific rating instrument that has been developed and validated by the EMSA-SG. The NHS comprises assessments of basic anthropometric data as well as a range of scales including the UMSARS, Unified Parkinson's Disease Rating Scale (UPDRS), measures of global disability, Red Flag list, MMSE (Mini Mental State Examination), quality of live measures, i.e. EuroQoL 5D (EQ-5D) and Medical Outcome Study Short Form (SF-36) as well as the Beck Depression Inventory (BDI). In a subgroup of patients dysautonomic features are recorded in detail using the Queen Square Cardiovascular Autonomic Function Test Battery, the Composite Autonomic Symptom Scale (COMPASS) and measurements of residual urinary volume. Most of these measures are repeated at 6-monthly follow up visits for a total study period of 24 months. Surrogate markers of the disease progression are identified by the EMSA-SG using magnetic resonance and diffusion weighted imaging (MRI and DWI, respectively). Results. 412 patients have been recruited into the Registry so far. Probable MSA-P was the most common diagnosis (49% of cases). 507 patients donated DNA for research. 131 patients have been recruited into the NHS. There was a rapid deterioration of the motor disorder (in particular akinesia) by 26.1% of the UMSARS II, and - to a lesser degree - of activities of daily living by 16.8% of the UMSARS I in relation to the respective baseline scores. Motor progression was associated with low motor or global disability as well as low akinesia or cerebellar subscores at baseline. Mental function did not deteriorate during this short follow up period. Conclusion. For the first time, prospective data concerning disease progression are available. Such data about the natural history and prognosis of MSA as well as surrogate markers of disease process allow planning and implementation of multi-centre phase II/III neuroprotective intervention trials within the next years more effectively. Indeed, a trial on growth hormone in MSA has just been completed, and another on minocycline will be completed by the end of this year.

Abstract
BACKGROUND Rasagiline mesylate is a novel drug for Parkinson's disease with selective, irreversible monoamine oxidase B (MAO-B) inhibitor activity, and is effective as monotherapy in early disease. This study investigated rasagiline efficacy and safety in levodopa-treated patients with Parkinson's disease and motor fluctuations. METHODS In an 18-week, double-blind, multicentre (74 hospitals and academic centres in Israel, Argentina, and Europe) trial, 687 outpatients were randomly assigned to oral rasagiline (231 individuals; 1 mg once daily), entacapone (227; 200 mg with every levodopa dose), or placebo (229). Primary outcome was change in total daily off-time (intention-to-treat population). Other measures included the clinical global improvement (CGI) score and unified Parkinson's disease rating scale (UPDRS) scores. Analysis was by intention to treat. FINDINGS 88 (13%) patients who were assigned treatment did not complete the study (23 rasagiline, 30 entacapone, 35 placebo), mainly because of withdrawal of consent (n=34) and adverse events (n=34). Both rasagiline and entacapone reduced mean daily off-time (-1.18 h rasagiline and -1.2 h entacapone vs placebo -0.4 h; p=0.0001, p<0.0001, respectively) and increased daily on-time without troublesome dyskinesia (0.85 h vs placebo 0.03 h; p=0.0005 for both). We recorded significant mean improvements in CGI scores (-0.86 rasagiline and -0.72 entacapone vs -0.37 placebo; p<0.0001, p=0.0002, respectively). Changes in UPDRS scores also significantly improved for activities of daily living during off-time (-1.71 and -1.38 vs placebo; p<0.0001, p=0.0006, respectively) and motor function during on-time (-2.94 and -2.73 vs placebo; both p<0.0001). Frequency of adverse events was similar for all treatments. INTERPRETATION Once-daily rasagiline reduces mean daily off-time and improves symptoms of Parkinson's disease in levodopa-treated patients with motor fluctuations, an effect similar to that of entacapone.

Abstract
Early diagnosis of dopa-responsive dystonia (DRD) and its delineation from other dystonic syndromes is of great relevance because DRD is an eminently treatable condition. The possible relevance of the phenylalanine loading test (Phe-L) in differentiating DRD from primary focal and generalized dystonia was investigated. A marked difference in the phenylalanine/tyrosine ratio between patients with DRD and patients with other types of dystonia was observed. This indicates that Phe-L may be helpful in the differential diagnosis of dystonias.

Abstract
OBJECTIVE To investigate whether it was possible to detect the presence and different levels of naturally occurring anti-beta-amyloid (Abeta) antibodies in the CSF of patients with AD and age-matched controls by employing a sensitive ELISA. BACKGROUND Immunization with preaggregated amyloid beta-peptide (Abeta(1-42)) and administration of antibodies against Abeta into amyloid precursor protein APP(V717F)- transgenic mice (an animal model of AD) have recently been reported to dramatically reduce amyloid plaque deposition, neuritic dystrophy, and astrogliosis, most likely by enhancing Abeta clearance from brain. METHODS A sensitive ELISA was performed to detect levels of naturally occurring anti-Abeta antibodies in the CSF of patients with AD and age-matched controls. Additionally, an immunoprecipitation assay was performed to confirm that naturally occurring anti-Abeta antibodies also exist in the human blood. RESULT - Naturally occurring antibodies directed against Abeta were found in the CSF and plasma of patients with AD and healthy control subjects. Moreover, CSF anti-Abeta antibody titers are significantly lower in patients with AD compared with healthy control subjects. CONCLUSION Naturally occurring antibodies directed against Abeta exist in human CSF and plasma. The CSF anti-Abeta antibody titers may be helpful in better understanding the effects of future immunologic therapies for AD.

Abstract
Brain amyloid load in Alzheimer's disease (AD) is, at least in genetic forms, associated with overproduction of amyloid beta-peptides (A beta). Thus, lowering A beta production is a central therapeutic target in AD and may be achieved by modulating such key enzymes of amyloid precursor protein (APP) processing as beta-, gamma-, and alpha-secretase activities. Talsaclidine is a selective muscarinic M1 agonist that stimulates the nonamyloidogenic alpha-secretase pathway in model systems. Talsaclidine was administered double-blind, placebo-controlled, and randomized to 24 AD patients and cerebrospinal fluid (CSF) levels of total A beta were quantitated before and after 4 weeks of drug treatment. We observed that talsaclidine decreases CSF levels of A beta significantly over time within the treatment group (n = 20) by a median of 16% as well as compared to placebo (n = 4) by a median of 27%. We conclude that treatment with selective M1 agonists may reduce A beta production and may thus be further evaluated as a potential amyloid-lowering therapy of AD.
