Abstract
BACKGROUND Progressive supranuclear palsy (PSP) is usually diagnosed in elderly. Currently, little is known about comorbidities and the co-medication in these patients. OBJECTIVES To explore the pattern of comorbidities and co-medication in PSP patients according to the known different phenotypes and in comparison with patients without neurodegenerative disease. METHODS Cross-sectional data of PSP and patients without neurodegenerative diseases (non-ND) were collected from three German multicenter observational studies (DescribePSP, ProPSP and DANCER). The prevalence of comorbidities according to WHO ICD-10 classification and the prevalence of drugs administered according to WHO ATC system were analyzed. Potential drug-drug interactions were evaluated using AiDKlinik®. RESULTS In total, 335 PSP and 275 non-ND patients were included in this analysis. The prevalence of diseases of the circulatory and the nervous system was higher in PSP at first level of ICD-10. Dorsopathies, diabetes mellitus, other nutritional deficiencies and polyneuropathies were more frequent in PSP at second level of ICD-10. In particular, the summed prevalence of cardiovascular and cerebrovascular diseases was higher in PSP patients. More drugs were administered in the PSP group leading to a greater percentage of patients with polypharmacy. Accordingly, the prevalence of potential drug-drug interactions was higher in PSP patients, especially severe and moderate interactions. CONCLUSIONS PSP patients possess a characteristic profile of comorbidities, particularly diabetes and cardiovascular diseases. The eminent burden of comorbidities and resulting polypharmacy should be carefully considered when treating PSP patients.

Abstract
BACKGROUND The impact of age of onset on the presentation of progressive supranuclear palsy phenotypes is not well studied. We hypothesized that there is difference in presentation and phenotype between young- and late-onset PSP. OBJECTIVES Our aim was to compare phenotypes and rate of change in disability between young-onset PSP (YOPSP) and late-onset PSP (LOPSP). METHODS Retrospective data of patients seen in the Rossy PSP Centre from March 2014 to April 2022 with clinical diagnosis of PSP as per the MDS 2017 diagnostic criteria were examined. We used cut-off age of 65 years to categorize the patients into YOPSP and LOPSP. We compared the prevalence of phenotypes, presenting symptoms, and MDS core criteria between the two groups. The severity of disease between the two groups was measured using PSP-RS. RESULTS We found 107 patients with clinical diagnosis of PSP as per MDS criteria, a third were defined as YOPSP. PSP speech/language (SL) phenotype was more prevalent in YOPSP (18% vs 0%, p < 0.001). Aphasia was significantly higher in YOPSP (16% vs 1.4%, p = 0.03). The speech and language dysfunction (C1) core criteria were more prevalent in YOPSP (33.3% vs 12.2%, p = 0.05). Longitudinal analysis of PSP-RS showed worsening of bulbar total score at 6 months in YOPSP (t (38) = 2.87; p = 0.05). CONCLUSION Our study revealed that YOPSP are more likely to present with a speech and language variant. Our results highlight that age of onset may predict PSP phenotypes, which holds both clinical and prognostic importance.

Abstract
BACKGROUND Most studies of progressive supranuclear palsy (PSP) have been conducted in White populations. OBJECTIVE The objective of this study was to identify whether differences exist for patients with PSP among Whites, East Asians (EAs), and Native Hawaiians/Pacific Islanders (NHPIs) in Hawaii. METHODS We conducted a single-center, retrospective study of patients meeting Movement Disorder Society probable PSP criteria (2006-2021). Data variables included age of onset and diagnosis, comorbidities, and survival rate. Variables were compared across groups using Fisher's exact test, Kruskal-Wallis rank sum test, and log-rank tests. RESULTS A total of 94 (59 EAs, 9 NHPIs, 16 Whites, and 10 Others) patients were identified. Mean age ± standard deviation (in years) of symptom onset/diagnosis were both youngest in NHPIs (64.0 ± 7.2/66.3 ± 8.0) followed by Whites (70.8 ± 7.6/73.9 ± 7.8), then EAs (75.9 ± 8.2/79.2 ± 8.3) (P < 0.001). Median survival from diagnosis was significantly lower (P < 0.05) in NHPIs (2 years) compared with EAs (4 years) and Whites (6 years). CONCLUSIONS There may be racial disparities for PSP, and studies are needed to identify genetic, environmental, and socioeconomic contributions. © 2023 International Parkinson and Movement Disorder Society.

Abstract
The objective of this study was to determine the prevalence, incidence, and clinical diagnostic accuracy for neuropathologically diagnosed progressive supranuclear palsy (PSP) with data from a longitudinal clinicopathological study using Rainwater criteria to define neuropathological PSP. Of 954 autopsy cases, 101 met Rainwater criteria for the neuropathologic diagnosis of PSP. Of these, 87 were termed clinicopathological PSP as they also had either dementia or parkinsonism or both. The prevalence of clinicopathologically defined PSP subjects in the entire autopsy dataset was 9.1%, while the incidence rate was estimated at 780 per 100 000 persons per year, roughly 50-fold greater than most previous clinically determined PSP incidence estimates. A clinical diagnosis of PSP was 99.6% specific but only 9.2% sensitive based on first examination, and 99.3% specific and 20.7% sensitive based on the final clinical exam. Of the clinicopathologically defined PSP cases, 35/87 (∼40%) had no form of parkinsonism at first assessment, while this decreased to 18/83 (21.7%) at final assessment. Our study confirms a high specificity but low sensitivity for the clinical diagnosis of PSP. The low clinical sensitivity for PSP is likely primarily responsible for previous underestimates of the PSP population incidence rate.

Abstract
Introduction We estimated the point prevalence of progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS) at regional and national levels in Scotland, UK as there are few high-quality prevalence studies of these conditions. Methods Nationally, multiple methods of case ascertainment were used including clinician and nurse specialist referral, searches of ICD-10 diagnostic coding in routinely collected electronic health data (Scottish Morbidity Record), and patient self-referral. In one region we also searched GP databases and unselected hospital correspondence. Cases were verified by clinical examination or medical record review. National and regional total and age-sex stratified crude prevalence rates on 31st December 2018 were calculated. Results The regional crude point prevalence was 4.28 per 100,000 (95% CI 2.90, 6.31) for PSP, and 2.05 per 100,000 (95% CI 1.17, 3.59) for CBS. The national crude prevalence rates were lower due to the greater reliance on passive case ascertainment. There were no clear sex differences. At a national level, the peak crude prevalence rate for both PSP and CBS was in the 70-79 age-group. Discussion The prevalence rates of PSP and CBS were similar to previous estimates with little change over the past 20 years.

Abstract
BACKGROUND Hashimoto's encephalopathy with serum anti-NH2-terminal of α-enolase (NAE) antibodies occasionally displays clinical symptoms such as cerebellar ataxia and parkinsonism. We studied the frequency of anti-NAE antibodies in patients with Parkinson-plus syndrome. METHODS We examined the positive rates of anti-NAE antibodies in 47 patients with multiple system atrophy (MSA), 29 patients with Parkinson's disease (PD), eight patients with corticobasal syndrome (CBS), and 18 patients with progressive supranuclear palsy (PSP) using conventional immunoblot analysis. RESULTS Positive anti-NAE antibody rates of 31.9%, 10.3%, 50.0%, and 11.1% were reported in the MSA, PD, CBS, and PSP patients, respectively. The duration from onset to a wheelchair-bound state in seropositive MSA patients tended to be shorter than that in seronegative MSA patients. CONCLUSIONS Anti-NAE antibodies are detected in some patients clinically diagnosed with MSA and CBS. Although its pathophysiological significance remains uncertain, serum anti-NAE antibodies might represent a prognostic marker in the clinical course of MSA.

Abstract
INTRODUCTION Data on epidemiology of atypical parkinsonian syndromes (APS) in North African countries are limited. Our objective was to study the epidemiological features of APS in a Tunisian population. METHODS We conducted a 17-year retrospective cross-sectional descriptive study in the Department of Neurology at Razi University Hospital. We included all patients responding to consensus diagnosis criteria of APS. We recorded demographic and clinical data. Group differences were assessed with a post hoc ANOVA with a Bonferroni error correction. RESULTS We included 464 APS patients. Hospital prevalence of APS among all parkinsonism cases was 20.6%. Mean annual increase of incidence defined as newly diagnosed APS cases per year reached 38.8%/year. APS were divided into 4 etiological subgroups: dementia with Lewy bodies (DLB; 56.7%); progressive supranuclear palsy(PSP; 16.2%); multiple system atrophy (MSA; 14.6%); and finally corticobasal syndrome (CBS; 12.5%). Sex-ratio was 1.2. This male predominance was found in all subgroups except MSA (p = .013). Mean age at onset was 68.5 years, most belated in DLB (69.7 years; p < .001). Young-onset parkinsonism (<40 years) was found only in MSA subgroup (p = .031). Parkinsonism was of late onset (>70 years) in 50.7% of patients and was significantly associated with DLB subgroup (p = .013). Inaugural parkinsonism was associated with CBS and MSA (p = .0497), and gait disorders at disease onset were associated with PSP and MSA (p = .0062). Cognitive and mood disorders were more marked in DLB and most preserved in MSA. Consanguinity was more marked in CBS (p = .037), and family history of dementia and psychiatric diseases was more common in DLB. Thirty-seven families with similar cases of APS were identified. CONCLUSIONS This is the largest African epidemiological study on APS. In our population, APS were frequent and dominated by DLB. The age of onset of parkinsonism was the most decisive feature for differential diagnosis.

Abstract
BACKGROUND Studies suggesting a protective effect of estrogen in neurodegenerative diseases prompted us to investigate this relationship in progressive supranuclear palsy (PSP). METHODS This case-control study evaluated the self-reported reproductive characteristics and estrogen of 150 women with PSP and 150 age-matched female controls who participated in the Environmental Genetic-PSP study. Conditional logistic regression models were generated to examine associations of PSP with estrogen. RESULTS There was no association between years of estrogen exposure duration and PSP. There was a suggestion of an inverse association between composite estrogen score and PSP that did not reach statistical significance (P = .06). Any exposure to estrogen replacement therapy halved the risk of PSP (odds ratio = 0.52; 95% confidence interval = 0.30-0.92; P = .03). Among PSP cases, earlier age at menarche was associated with better performance on Hoehn and Yahr stage (β = -0.60; SE = 0.26; P = .02) and Unified Parkinson's Disease Rating Scale II score (β = -5.19; SE = 2.48; P = .04) at clinical examination. CONCLUSIONS This case-control study suggests a protective role of lifetime estrogen exposure in PSP. Future studies will be needed to confirm this association. © 2018 International Parkinson and Movement Disorder Society.

Abstract
INTRODUCTION Tremor is thought to be a rare feature of progressive supranuclear palsy (PSP). METHODS We retrospectively reviewed the database of the CurePSP brain bank at Mayo Clinic Florida to retrieve all available clinical information for PSP patients. All patients underwent a standard neuropathological assessment and an immunohistochemical evaluation for tau and α-synuclein. DNA was genotyped for the MAPT H1/H2 haplotype. RESULTS Of the 375 PSP patients identified, 344 had a documented presence or absence of tremor, which included 146 (42%) with tremor, including 29 (20%) with postural/action tremors, 16 (11%) with resting tremor, 7 (5%) with intention tremor, 20 (14%) with a combination of different types of tremor, and 74 (51%) patients who had tremor at some point during their illness, but details were unavailable. The tremor severity of 96% of the patients (54/55) who had this data was minimal to mild. The probability of observing a tremor during a neurological examination during the patient's illness was estimated to be ∼22%. PSP patients with postural/action tremors and PSP patients with resting tremor responded to carbidopa-levodopa therapy more frequently than PSP patients without tremor, although the therapy response was always transient. There were no significant differences in pathological findings between the tremor groups. CONCLUSIONS Tremor is an inconspicuous feature of PSP; however, 42% (146/344) of the PSP patients in our study presented some form of tremor. Because there is no curative therapy for PSP, carbidopa/levodopa therapy should be tried for patients with postural, action, and resting tremor.

Abstract
BACKGROUND Seven Tesla (7T) MRI can visualize anatomical alterations occurring in a hyperintense structure of the substantia nigra in Parkinson's disease (PD). OBJECTIVE We investigated whether 7T MRI can detect the loss of substantia nigra hyperintensity in patients with PD, multiple system atrophy (MSA), and progressive supranuclear palsy (PSP). METHODS Using 7T MRI, we evaluated 26 healthy subjects, 30 patients with PD, 7 patients with MSA, and 3 patients with PSP. Two blinded readers independently assessed the images. We carried out a comparative analysis of five patients with hemiparkinsonism via (123)I-2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl)-nortropane ((123)I-FP-CIT) SPECT. RESULTS 7T MRI revealed a definitive shape of nigral hyperintensity in healthy subjects, nearly identical to neuropathological characterization of nigrosome 1, and enabled instantaneous determination of its presence or absence in all subjects. Nigral hyperintensity was lost in all patients with PD, MSA with predominant parkinsonism, and PSP. One of five patients with MSA with predominant cerebellar ataxia showed an intact nigral hyperintensity. The side effects were mild and tolerable, and imaging was successful in patients with dyskinesia. Motion artifact incidence was higher in elderly subjects. In hemiparkinsonism cases, we observed partial loss of nigral hyperintensity on the side of less reduced (123)I-FP-CIT binding, suggesting an ongoing iron deposition on the unaffected side in hemiparkinsonism. CONCLUSIONS The present findings suggest that 7T MRI represents an excellent tool for evaluating nigral hyperintensity in PD, MSA, and PSP, with tolerable side effects and limited motion artifacts. Thus, imaging of parkinsonism may benefit from using 7T MRI.

Abstract
INTRODUCTION There have been few incidence studies of vascular parkinsonism (VP), progressive supranuclear palsy (PSP), and parkinsonian-type multiple system atrophy (MSA-P). We measured the age-, gender- and socioeconomic-specific incidence rates for these conditions in north-east Scotland. METHODS Incident non drug-induced parkinsonian patients were identified prospectively over three years by several overlapping methods from a baseline primary care population of 311,357. Parkinsonism was diagnosed if patients had two or more cardinal motor signs. Patients had yearly follow-up to improve diagnostic accuracy. Incidence rates using the diagnosis by established research criteria at latest follow-up were calculated for each condition by age, gender, and socioeconomic status. RESULTS Of 377 patients identified at baseline with possible or probable parkinsonism, 363 were confirmed as incident patients after median follow-up of 26 months (mean age 74.8 years, SD 9.8; 61% men). The crude annual incidence was 3.2 per 100,000 (95% confidence interval (CI) 2.2-4.3) for VP, 1.7 per 100,000 (95% CI 1.0-2.4) for PSP, and 1.4 per 100,000 (95% CI 0.8-2.1) for MSA-P. VP and MSA-P were more common in men (age-adjusted male to female ratios 2.58 (95% CI 1.65-3.83) and 8.65 (95% CI 4.73-14.5) respectively). Incidence did not vary with socioeconomic status. DISCUSSION This is the first community-based, prospective study to report the incidence of vascular parkinsonism and the third to report the incidence of PSP and MSA-P. Further follow-up and comparison with similar studies in different populations will yield valuable prognostic and aetiological information on these conditions.

Abstract
INTRODUCTION Movement disorder specialists can achieve a high level of accuracy when clinically diagnosing parkinsonism syndromes. However, data about the diagnostic accuracy among general neurologists is limited. OBJECTIVES This study investigated the recent diagnostic accuracy of parkinsonism syndromes by general neurologists. METHODS A retrospective examination of 1362 post-mortem cases diagnosed in the years 2000-2012 by neuropathologists was performed. Out of these cases, we identified 111 patients who received a clinical parkinsonism diagnosis during life and 122 patients who received a neuropathological diagnosis of a parkinsonism syndrome post-mortem including 11 incidental cases. RESULTS Fifty-eight (75.3%) of the 77 patients who had received clinical Parkinson's disease (PD) diagnoses were confirmed after the neuropathological examination. The sensitivity of the clinical diagnosis for idiopathic Parkinson's disease (PD) was 89.2% and the specificity was 57.8%. The corresponding numbers for progressive supranuclear palsy (PSP) were 52.9% and 100%, and for multiple system atrophy (MSA) were 64.3% and 99.0%, respectively. CONCLUSIONS Parkinson's disease is heavily overdiagnosed by general neurologists, whereas parkinsonism plus syndromes are underdiagnosed. Despite improvements in the diagnostic methods during recent decades and the development of diagnostic clinical criteria for parkinsonian syndromes, the diagnostic accuracy of Parkinson's disease remains relatively low, and 1/4 of diagnoses are incorrect.

Abstract
Progressive supranuclear palsy (PSP), or Steele-Richardson-Olszewski syndrome, is a rare, progressive neurodegenerative condition with cognitive and motor involvement. Diagnosis can be challenging as some people do not display the classic symptoms of the condition and there are no specific investigations to confirm diagnosis. Timely discussions and access to symptom management and palliative care services need to be provided from diagnosis throughout the disease trajectory to ensure holistic care of people with PSP.

Abstract
OBJECTIVES Visual hallucinations (VH) occur frequently in Parkinson's disease (PD) and dementia with Lewy bodies (DLB) and are much less common in other bradykinetic rigid syndromes. Pathological series suggest that the presence of VH is highly specific for Lewy body pathology. To address the issue of diagnosis in patients with parkinsonism, we developed instructions for a structured interview (Queen Square Visual Hallucination Inventory (QSVHI)), capable of rapidly screening for VH in the outpatient setting. METHODS 181 consecutive patients from a specialist movement disorders clinic were tested (115 with PD, 23 with progressive supranuclear palsy (PSP), 9 with multiple system atrophy (MSA), 5 with vascular parkinsonism, 19 with unclassifiable parkinsonism (UP) and 8 others), and 15 selected patients from other clinics and 14 neurologically normal controls. The characteristics of hallucinators and non-hallucinators were compared and the sensitivity, specificity and predictive values of VH for a clinical diagnosis of PD calculated. RESULTS Screening questions identified VH in only 38% of patients with PD. The QSVHI identified VH in 75% of patients with PD and 47% of those with UP. The specificity of VH identified by the QSVHI for PD was 91%, sensitivity was 62%, positive predictive value was 95% and negative predictive value was 48%. CONCLUSIONS The QSVHI appears to be a sensitive method for identifying VH in a movement disorders clinic. VH occurred predominantly in PD and very rarely in PSP and MSA. Among patients with unclassifiable or undetermined parkinsonism, the presence of VH should be considered a red flag for underlying Lewy body pathology.

Abstract
BACKGROUND Progressive supranuclear palsy (PSP) is a progressive hypokinetic rigid disorder with supranuclear gaze palsy and frequent falls. Although clinical consensus criteria are available, an atypical presentation may lead to clinical misdiagnosis in the initial phase. In the present study we investigated the clinical presentation of PSP and its relationship to initial clinical diagnosis and survival. METHODS We ascertained patients with PSP in a prospective cohort by nationwide referral from neurologists and nursing home physicians. All patients underwent a structural interview and clinical examination before entering the study. Medical records were reviewed for the presence of symptoms during the first 2 years. RESULTS A total of 152 patients ascertained between 2002 and 2005 fulfilled the international consensus criteria for PSP. Categorical principal component analysis of clinical symptoms within the first 2 years showed apart from a cluster of typical PSP symptoms, the clustering of cognitive dysfunction and behavioral changes. Further analysis showed that 20% of patients had a predominant frontal presentation with less than two other PSP symptoms. Survival analysis showed that this subgroup had a similar prognosis to that of the total group of patients with PSP. CONCLUSIONS There exists a subgroup of patients with progressive supranuclear palsy (PSP) with a predominant frontal presentation, who progressed into typical PSP over the course of the disease.

Abstract
In Guadeloupe, there is an abnormally high frequency of atypical parkinsonism. Only one-third of the patients that develop parkinsonian symptoms were reported to present the classical features of idiopathic Parkinson disease and one-third a syndrome resembling progressive supranuclear palsy (PSP). The others were unclassifiable, according to established criteria. We carried out a cross-sectional study of 160 parkinsonian patients to: (i) define more precisely the clinical phenotypes of the PSP-like syndrome and the parkinsonism that was considered unclassifiable in comparison with previously known disorders; (ii) define the neuropsychological and brain imaging features of these patients; (iii) evaluate to what extent a candidate aetiological factor, the mitochondrial complex I inhibitor annonacin contained in the fruit and leaves of the tropical plant Annona muricata (soursop) plays a role in the neurological syndrome. Neuropsychological tests and MRI were used to classify the patients into those with Parkinson's disease (31%), Guadeloupean PSP-like syndrome (32%), Guadeloupean parkinsonism-dementia complex (PDC, 31%) and other parkinsonism-related disorders (6%). Patients with a PSP-like syndrome developed levodopa-resistant parkinsonism, associated with early postural instability and supranuclear oculomotor dysfunction. They differed, however, from classical PSP patients by the frequency of tremor (>50%), dysautonomia (50%) and the occurrence of hallucinations (59%). PDC patients had levodopa-resistant parkinsonism associated with frontosubcortical dementia, 52% of these patients had hallucinations, but, importantly, none had oculomotor dysfunction. The pattern of neuropsychological deficits was similar in both subgroups. Cerebral atrophy was seen in the majority of the PSP-like and PDC patients, with enlargement of the third ventricle and marked T2-hypointensity in the basal ganglia, particularly the substantia nigra. Consumption of soursop was significantly greater in both PSP-like and PDC patients than in controls and Parkinson's disease patients. In conclusion, atypical Guadeloupean parkinsonism comprises two forms of parkinsonism and dementia that differ clinically by the presence of oculomotor signs, but have similar cognitive profiles and neuroimaging features, suggesting that they may constitute a single disease entity, and both were similarly exposed to annonaceous neurotoxins, notably annonacin.

Abstract
Dopaminergic imaging has been found to be normal in approximately 15% of parkinsonian patients enrolled in neuroprotective trials. We used (18)F-fluorodeoxyglucose positron emission tomography (FDG PET) to determine the metabolic basis for this finding. We reviewed scans from 185 patients with clinical signs of Parkinson's disease (PD) who underwent (18)F-fluorodopa PET imaging for diagnostic confirmation. Of this group, 27 patients (14.6%) had quantitatively normal scans; 8 of these patients were additionally scanned with FDG PET. Pattern analysis was performed on an individual scan basis to determine whether the metabolic changes were consistent with classic PD. Computer-assisted single-case assessments of the FDG PET scans of these 8 patients did not disclose patterns of regional metabolic change compatible with classical PD or an atypical parkinsonian variant. Similarly, network quantification revealed that PD-related pattern expression was not elevated in these patients as it was in an age- and duration-matched cohort with classical PD (P < 0.0001). None of these patients developed clinical signs of classical PD or of an atypical parkinsonian syndrome at a follow-up visit conducted 3 years after imaging. The results suggest that parkinsonian subjects with normal dopaminergic imaging do not have evidence of classical PD or an atypical parkinsonian syndrome.

Abstract
Progressive supranuclear palsy (PSP), a neurodegenerative disorder that may be mistaken for Parkinson's disease early in its course, is the most common type of atypical parkinsonism. PSP is fatal; it transforms a normal person into an invalid within 5-7 years of the onset of symptoms. PSP requires a multidisciplinary approach to symptom management and treatment. The neuroscience nurse who is knowledgeable about PSP and the complex way in which it overlaps with numerous other devastating neurological diagnoses can help in achieving the correct diagnosis and treatment. The nurse must understand the disease pathophysiology and the plan of care required and is instrumental in recognizing the needs of the patient and the family.

Abstract
We examined sex-based differences in phenotypic expression among a consecutive clinical series of 121 individuals diagnosed with probable progressive supranuclear palsy (PSP). For both men (44%) and women (56%), the age at symptomatic onset (66.2 and 68.5 years, respectively) and disease duration (4.6 and 4.3 years, respectively) were similar. The overwhelming majority of sex-based comparisons showed no significant difference on a variety of demographic, historical, and clinical characteristics, as well as measures of disease progression. The only differences observed were that men had significantly worse tremor as measured by the Unified Parkinson's Disease Rating Scale tremor subscore (0.9 for men and 0.3 for women, P<0.01) and men had a significantly higher mean body mass index (BMI; 28.2 for men and 25.1 for women, P=0.01), although these differences were not significant after Bonferroni correction. In general, the disease phenotype was similar between men and women, suggesting that sex may have little or no influence on the development, expression, or progression of the PSP phenotype.

Abstract
OBJECTIVES Visuospatial deficits have been occasionally reported but never systematically studied in atypical parkinsonian syndromes. The interpretation of existing studies is complicated by the possible influence of motor and frontal executive deficits. Moreover, no attempt has been made to distinguish visuoperceptual from visuospatial tasks. The aim of the present study was to assess visuoperceptual and visuospatial abilities in three atypical parkinsonian syndromes while minimising the influence of confounding variables. METHODS Twenty patients with multiple system atrophy (MSA), 43 with progressive supranuclear palsy (PSP), and 25 with corticobasal degeneration (CBD) as well as 30 healthy age matched controls were examined with the Visual Object and Space Perception Battery (VOSP). RESULTS Visuospatial functions were intact in MSA patients. PSP patients showed mild deficits related to general cognitive decline and the severity of oculomotor symptoms. The CBD group showed the most pronounced deficits, with spatial tasks more impaired than object based tasks. Performance on object based, but not spatial, tasks was related to general cognitive status. The extent of the visuospatial impairment could not be predicted from disease duration or severity. CONCLUSION Visuospatial functions are not consistently impaired in atypical parkinsonian syndromes. The degree and pattern of impairment varies across the diseases, suggesting that the observed deficits could have a different neural basis in each condition. The distinction between the object based ("ventral stream") and the space oriented ("dorsal stream") processing might be useful in the interpretation of visuospatial deficits in parkinsonian syndromes, especially in CBD.

Abstract
BACKGROUND Falls and fractures contribute to morbidity and mortality in bradykinetic rigid syndromes. METHODS The authors performed a retrospective case notes review at the Queen Square Brain Bank for Neurological Disorders and systematically explored the relation between clinical features and falls and fractures in 782 pathologically diagnosed cases (474 with Parkinson's disease (PD); 127 progressive supranuclear palsy (PSP); 91 multiple system atrophy (MSA); 46 dementia with Lewy bodies (DLB); 27 vascular parkinsonism; nine Alzheimer's disease; eight corticobasal degeneration). RESULTS Falls were recorded in 606 (77.5%) and fractures in 134 (17.1%). In PD, female gender, symmetrical onset, postural instability, and autonomic instability all independently predicted time to first fall. In PD, PSP, and MSA latency to first fall was shortest in those with older age of onset of disease. Median latency from disease onset to first fall was shortest in Richardson's syndrome (12 months), MSA (42), and PSP-parkinsonism (47), and longest in PD (108). In all patients fractures of the hip were more than twice as common as wrist and forearm fractures. Fractures of the skull, ribs, and vertebrae occurred more frequently in PSP than in other diseases. CONCLUSION Measures to prevent the morbidity associated with falls and fractures in bradykinetic rigid syndromes may be best directed at patients with the risk factors identified in this study.

Abstract
On Guam and in two other Pacific locales, indigenous residents and immigrants are prone to familial neurodegeneration that manifests as atypical parkinsonism, dementia, motor neuron disease, or a combination of these three phenotypes. This progressive and fatal disease of the Mariana islands, the Kii peninsula of Japan, and the coastal plain of West New Guinea is similar and the pathological features have close affiliation with universal tauopathies, including progressive supranuclear palsy, Alzheimer's disease, and amyotrophic lateral sclerosis. The Chamorros of Guam call the disease lytico-bodig, and neuroscientists refer to it as the amyotrophic lateral sclerosis/Parkinsonism-dementia complex. During recent decades, its prevalence has declined progressively, and the age at onset has steadily increased. In 2004, motor neuron disease, once 100 times more common than elsewhere is rare, atypical parkinsonism is declining, and only dementia remains unusually common in elderly females. The cause of this obscure malady remains uncertain, despite 60 years of international research, but its ending implicates environmental influences rather than genetic predisposition.

Abstract
STUDY OBJECTIVE To compare sleep characteristics, rapid eye movement (REM) sleep without atonia, and REM sleep behavior disorder (RBD) in patients with progressive supranuclear palsy (tauopathy), patients with Parkinson's disease (a synucleinopathy), and control subjects. DESIGN Sleep interview, overnight polysomnography, and Multiple Sleep Latency Tests. PATIENTS Forty-five age- and sex-matched patients with probable progressive supranuclear palsy, (n=15, aged 68 +/- 8 years, 7 men), patients with Parkinson disease (n=15), and control subjects (n=15). SETTINGS Tertiary-care academic hospital. INTERVENTION N/A. RESULTS Compared to the 2 other groups, patients with progressive supranuclear palsy had a longer duration of wakefulness after sleep onset and twice as much sleep fragmentation and percentage of stage 1 sleep but had similar apnea-hypopnea indexes, periodic leg movements indexes, and mean daytime sleep latencies. REM sleep percentage was as low in patients with progressive supranuclear palsy (8% +/- 6% of total sleep time) as in patients with Parkinson disease (10% +/- 4%), versus 20% +/- 6% in controls (analysis of variance, P < .0001). Interestingly, patients with progressive supranuclear palsy had percentages of REM sleep without atonia (chin muscle activity: 33% +/- 36% of REM sleep) similar to those of patients with Parkinson disease (28% +/- 35%) and dramatically higher than those of controls (0.5% +/- 1%, analysis of variance, P = .008). Four (27%) patients with progressive supranuclear palsy had more than 50% REM sleep without atonia (as did a similar number of patients with Parkinson disease), and 2 of them (13%, vs 20% of patients with Parkinson disease) had clinical RBD. The four patients with progressive supranuclear palsy with excessive daytime sleepiness slept longer at night than the 11 patients with progressive supranuclear palsy who were alert (442 +/- 14 minutes vs 312 +/- 74 minutes, student t tests, P = .004), suggesting a primary nonnarcoleptic hypersomnia. CONCLUSION REM sleep without atonia and RBD were as frequent in patients with progressive supranuclear palsy as in patients with Parkinson disease. It suggests that the downstream cause of parkinsonism, rather than its primary neuropathology (synucleinopathy vs tauopathy), is a key factor for REM sleep behavior disorder.

Abstract
There have been few reports of the prevalence of progressive supranuclear palsy (PSP): the present study examines its prevalence in Japan and compares the findings with those in Europe and the United States. The prevalence per 100,000 was 5.82 (men, 9.14; women, 2.75), and the 95% confidence interval was 1.78 to 9.86 (men, 1.82-16.47; women, -1.08-6.65). Our data were comparable to those of studies in Europe and the United States.

Abstract
INTRODUCTION Progressive supranuclear palsy is a disease that normally presents only sporadically in adults and courses in a progressive, chronic manner. It is characterised by the presence of supranuclear ophthalmoplegia, postural instability, a Parkinsonian syndrome, pseudobulbar affect, cervical dystonia and cognitive impairment. PATIENTS AND METHODS We conducted a descriptive study of clinical and epidemiological features in a series of 18 patients who satisfied the mandatory NINDS-SPSP clinical eligibility criteria for the likely diagnosis of progressive supranuclear palsy, using the scale developed by Golbe et al. RESULTS AND CONCLUSIONS The mean age of onset of the disease was 58.6 +/- 8.2 years, 55.5% of the patients were males, the average history of the disease at the time of diagnosis was 4.39 +/- 2.3 years, and there was a diagnostic subregister in the first 4 years of the disease. Gait disorders, falls and slowness were the most frequently observed presenting forms of the disease. During their first four years with the disease, 75% of the patients were totally independent when it came to carrying out activities of daily living, whereas after the fourth year there was a predominance of the need for aid and absolute dependence. Dysphagia was more frequent in the later stages of the disease. Ocular motility disorders and impaired cognitive functioning were obvious in the initial stages of the disease, and there was a strong correlation between the length of time the disease had been coursing and the severity of the ocular and cognitive disorders.

Abstract
Progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are sporadic neurodegenerative diseases presenting as atypical parkinsonian disorders, characterized by the presence of tau-positive neurofibrillary tangles. Recently, an extended haplotype (H1E) of 787.6 kb that comprises several genes including MAPT showed increased association with PSP. The objective of this study was to determine the size of the H1E haplotype associated with PSP and CBD in different populations and to identify specific subhaplotypes in the background of H1E haplotype. Nineteen single nucleotide polymorphisms (SNPs) in the 17q21 region were genotyped in two case-control samples. The SNPs that were associated with higher risk for the disease in the homozygous state delimit a region of more that 1 Mb. Haplotype analyses in the Spanish sample showed that the most frequent haplotype found among the patients (H1E'), which extends 1.04 Mb and contains several genes such as MAPT, CRHR1, IMP5, Saitohin, WTN3, and NSF. A specific subhaplotype (H1E'A) was present in 16% of PSP patients but was not observed in the controls. Furthermore, the H2E'A haplotype, was rarely present in the disease group suggesting that it plays a protective role. The identification of these specific subhaplotypes that modify risk for PSP/CBD supports the hypothesis that a pathogenic allele exists in a subgroup of PSP patients.

Abstract
Neuroimaging studies of the dopaminergic system with positron emission tomography and single photon emission computed tomography radioligands are useful in the assessment of neuronal degeneration in Parkinson's disease. Abnormalities can be identified early in the disease process and used to monitor progression as well as the effect of treatment. Studies of dopamine receptors and brain metabolism can help identify those patients who have other Parkinsonian syndromes, such as multiple system atrophy, progressive sopranuclear palsy or diffuse Lewy body dementia. The current available diagnostic criteria for these disorders rely solely on the presence of signs and symptoms that may require months or years to become fully clinically manifest. Conversely, the use of neuroimaging techniques can significantly shorten the diagnostic process and prove a useful means to the neurologist in those cases presenting with uncertain clinical diagnosis.

Abstract
Sleep disturbances are common in extrapyramidal diseases, including not only insomnia but excessive daytime sleepiness and parasomnias. In particular, complaints related to sleep are extremely common among patients affected by Parkinson's disease (PD). The underlying causes may include: patient age, associated illnesses, cognitive impairment, motor dysfunction caused by disease, neurochemical changes related to the disease, drugs, and secondary psychological responses to the disease. The exact prevalence of sleep disorders in PD is difficult to ascertain, due to the heterogeneity of patients as well as to the different criteria and methods used to diagnose and classify sleep disturbances. In this study, we will attempt to review the epidemiological data and to describe the various sleep disorders, which have been identified in extrapyramidal diseases, with particular reference to PD. There are no data available at present as to the role of gender in sleep disturbances. Finally, the benefit of sleep on extrapyramidal diseases will be addressed, taking into account that the above causes may modify the effects of sleep.

Abstract
The cause of progressive supranuclear palsy (PSP), the most common form of the atypical parkinsonian disorders, is unknown. PSP is characterized by four-repeat tau aggregates in neurons (neurofibrillary tangles) and glia in specific basal ganglia and brainstem areas. A thorough literature review led us to hypothesize that genetic and/or environmental factors contribute to its development. It is likely that inheritance of the H1/H1 tau genotype represents a predisposition to develop PSP requiring other environmental or genetic factors. Less likely, a relatively rare mutation with low penetrance could contribute to the abnormal tau aggregation present in this disorder. The possible role of chemicals in the diet or occupation, hypertension, traumatic brain injury, coffee, and inflammation or oxidative injury are reviewed.

Abstract
It has been reported that up to 80% of patients clinically diagnosed as having progressive supranuclear palsy (PSP) may have arterial hypertension (HT). Because previous studies were performed on patients with presumed diagnosis of PSP, we tried to replicate these studies in a series of pathologically confirmed patients. Seventy-three patients with a neuropathological diagnosis of PSP autopsied at the Queen Square Brain Bank for Neurological Disorders in London were collected between 1989 and 1999. For the purpose of this study, patients were considered hypertensive if a blood pressure above 140/90 mm Hg was found in the clinical records. The prevalence of HT in PSP patients at the first and at the last visit during their neurological disease was compared with that found in a series of 21 normal controls who donated their brain to the same institution. Overall, 29 of 73 (39.7%) of the patients were recorded as having HT at the first visit during the disease course; this ratio increased to 42 of 73 (57.5%) at the last visit before death. When these figures were compared to the 21 normal controls (11 of 21 with HT, 52.4%), we were unable to find an increased prevalence of HT in PSP (odds ratio, 0.60; 95% confidence interval, 0.20-1.76). Therefore, HT does not represent an important clinical feature of this neurodegenerative disorder, although cerebrovascular disease can masquerade clinically as PSP.

Abstract
This review provides an update on progressive supranuclear palsy (PSP, or Steele-Richardson-Olszewski disease), an adult-onset neurodegenerative disorder characterised by early postural instability, which leads to falls, and a vertical supranuclear-gaze palsy. Recent epidemiological studies have shown that the disorder is more common than previously recognised, that it is commonly misdiagnosed, and that it may present to a wide range of hospital specialists. The diagnosis of PSP hinges on clinical acumen. Attempts to identify a suitable biomarker in the CSF or a specific and sensitive imaging or neurophysiological technique have so far failed to have a significant effect on the diagnostic process. Better understanding of the molecular pathology of PSP has highlighted the importance of tau-protein accumulation and tau-genotype susceptibility in its pathogenesis. No drug treatment significantly and consistently benefits patients, and novel therapies are urgently required.

Abstract
We report the number of pathologically proven cases of progressive supranuclear palsy, described in the Italian neurological literature from 1961 until now. A discussion of the diagnostic value of downward gaze palsy is made. A comparison with the number of similar cases described in the rest of the world and with the number of Parkinsonian patients who died in the same region in the corresponding year is attempted.

Abstract
PURPOSE OF THE REVIEW This review focuses on the recent additions to the literature in the clinical and genetic aspects of progressive supranuclear palsy. RECENT FINDINGS Clinical features of progressive supranuclear palsy are reasonably well established and known to be quite characteristic. Recent epidemiological studies suggest that the disorder is more common than previously considered and that it is frequently misdiagnosed. New laboratory and novel imaging techniques are being tested and cerebrospinal fluid levels of tau protein have been found helpful in diagnosis. Pathological and biochemical studies in progressive supranuclear palsy brains have shown the predominance of hyperphosphorylated tau isoforms which contain the sequence encoded by exon 10 (4R) aggregated into filaments. Familial tauopathies linked to tau gene mutations showing clinical and neuropathological overlap with sporadic progressive supranuclear palsy have been described. Despite recent discoveries of the strong genetic association of sporadic progressive supranuclear palsy with tau gene polymorphisms, a specific risk allele for developing the palsy has not yet been identified yet. SUMMARY Recent clinical studies and clinicopathological correlations are contributing significantly to the delineation of the clinical features of progressive supranuclear palsy. These features and the appropriate use of laboratory tests allow for an earlier identification of the disease and a more accurate premortem diagnosis. However, no specific biological markers for the disorder are available yet, and consequently diagnosis in the early stages or when some of the characteristic signs and symptoms are missing, remains a major challenge. Despite the recent advances in the understanding of genetic factors involved in progressive supranuclear palsy, the cause of the disease still remains unknown. Biochemical studies in brains from progressive supranuclear palsy patients provide a potential helpful instrument to improve the characterization of this disorder.

Abstract
The recent finding of disequilibrium among several polymorphisms along the tau gene and the strong association of one of the two haplotypes formed by these polymorphisms (H1) with progressive supranuclear palsy (PSP) suggests that a single allele in or near the tau gene at 17q21 is responsible for increased risk in most of the PSP cases. We sought to determine whether mutations in the tau gene are responsible for the disease in 45 sporadic PSP patients. Furthermore, we analyzed some markers located in the common region of linkage (D17S800-D17S791), associated with some cases of familial frontotemporal dementia (FTDP-17), and the SNPs rs1816 and rs937 close to the tau gene, to determine their possible association with sporadic PSP. We did not find pathogenic mutations in exons 9, 10, 12, or 13 of the tau gene, indicating that tau mutations in both the splice-site region of the exon 10 and in the microtubule-binding region of tau gene are not a cause of PSP in this study group. We found significant overrepresentation of the haplotypes H1, extended up to the promoter of the tau gene (H1P), in PSP patients as compared with controls. In addition, a significant overrepresentation of the D17S810 2/2 and 3/2 genotypes, of the SNP rs1816 A/A, and of the SNP rs937 delG/delG genotypes was detected in PSP, further extending the haplotype described previously. These results are consistent with the hypothesis that a change either in the 5' or in the 3' flanking regions of the tau gene, or even other genes contained in the H1E haplotype, could increase the genetic susceptibility to PSP.

Abstract
Genetic studies have shown that progressive supranuclear palsy (PSP) is associated with inheritance of a specific genotype (H1/H1) in the tau gene. The authors investigated whether the H1/H1 genotype or A0/A0 genotype independently or in conjunction with selected environmental risk factors influences the age at onset, severity, or survival in patients with PSP. Our findings suggest that tau genotyping does not predict the prognosis of PSP.

Abstract
We performed a study to estimate the point prevalence of progressive supranuclear palsy (PSP) in the UK at national, regional and community levels. A 'Russian doll' design was used in which the population denominator for each of the three studies was successively smaller, whilst the method of case ascertainment became increasingly more rigorous. The NINDS-SPSP (National Institute of Neurological Disorders and the Society for Progressive Supranuclear Palsy) diagnostic criteria for PSP were applied throughout the study for case definition. The national study identified cases using passive referral mechanisms [e.g. the British Neurological Surveillance Unit (BNSU), PSP (Europe) Association patient register]. We identified 577 cases of PSP, giving a national prevalence estimate of 1.0 per 100 000 [95% confidence interval (CI) 0.9-1.1]. The North of England regional study used active 'multiple source' case ascertainment from a collaborative network of neurologists and non-neurologists. We identified 80 cases of PSP in this study, giving a crude and age-adjusted prevalence of 3.1 (95% CI 2.4-3.8) and 2.4 (1.9-3.0) per 100 000, respectively. Of these 80 cases, 51 patients (65%) were referred initially to non-neurologists and 10 patients (13%) had not seen a neurologist at any stage of their illness. The proportion of female cases was significantly greater in the regional than in the national study (61% versus 44%; P < 0.02). Cases referred to non-neurologists were significantly older than those referred to neurologists in the regional study (median age 73 versus 69.5 years; P < 0.01). Patients in the community study were identified via diagnostic and therapeutic registers from a representative sample of general practices in Newcastle upon Tyne. We identified 17 cases of PSP, yielding crude and age-adjusted prevalences of 6.5 (95% CI 3.4-9.7) and 5.0 (95% CI 2.5-7.5) per 100 000, respectively. Seven of the 17 cases (41%) had not previously been diagnosed as PSP. This study suggests that PSP is more common than previously considered, is commonly misdiagnosed and that the majority of cases are not initially referred to neurologists. The study also confirms the importance of active and detailed case ascertainment in ensuring reliable prevalence estimates.

Abstract
Progressive supranuclear palsy (PSP) is a rare form of parkinsonism. The incidence rates are about 0.3-1.1 cases per 100,000 persons. The only two case-control studies performed up to now show conflictual results as regards education and residence in rural areas. Recently, a cluster of PSP and atypical parkinsonism has been observed in French Antilles. The hypothesis is that a consumption of both tropical fruit and herbal tea may be associated with PSP onset. Some PSP families with a probably autosomal dominant transmission have been described. A high frequency of a tau haplotype (H1/H1) associated with PSP is reported by some authors. The significance of this association is still not clear. We have performed a case-control study on 58 PSP cases, 116 hospital controls and 58 population controls.

Abstract
OBJECTIVE To determine whether there is a greater prevalence of asymptomatic first-degree relatives (FDR) of patients with progressive supranuclear palsy (PSP) performing abnormally on the PD test battery (PD Battery) compared to sex- and age-matched normal control (NC) individuals. The PD Battery incorporates tests of motor function, olfaction, and mood. It has high specificity and sensitivity in distinguishing mildly affected PD patients from NC individuals in previous studies. METHODS This test battery and regression analysis-derived scoring equations were applied to asymptomatic FDR. RESULTS Twenty-three FDR and 23 NC individuals were tested. Of the FDR, 39% scored in the abnormal range, whereas none of the NC individuals achieved abnormal scores. This difference was significant. Further analysis demonstrated that the two groups differed significantly on a measure of simple reaction time. CONCLUSIONS The proportion of FDR who demonstrated abnormal performance on the PD Battery was greater than NC individuals. Thus, the PD Battery may detect the asymptomatic carrier state or risk for PSP or a subclinical effect of a shared environmental exposure.

Abstract
We and others have previously identified two distinct haplotypes of the TAU gene in Caucasian populations. In this study, we have assessed whether these haplotypes show an association with Alzheimer's disease in a variety of populations. They do not. These data are consistent with the view that the involvement of TAU in Alzheimer's disease is a downstream event.

Abstract
BACKGROUND The prevalence of progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) in the general population is unknown. Clinicopathological studies of patients diagnosed as having Parkinson's disease suggest that the two disorders may be underdiagnosed. We investigated the population prevalence of these disorders. METHODS We screened computerised records of 15 general practices in London, UK, for patients with specific diagnostic labels suggestive of Parkinson's disease or parkinsonism and all patients who had ever received antiparkinsonian medication. We assessed eligible patients by review of records, interview, physical examination, and video recordings of neurological signs for independent diagnostic confirmation. We diagnosed parkinsonian disorders according to published criteria and further reviewed patients with atypical features after 1 year. FINDINGS The participation rate was 84%. The age-adjusted prevalence for PSP was 6.4 per 100,000 (five probable and one possible case [95% CI 2.3-10.6]) and for MSA 4.4 per 100,000 (two probable and two possible cases [1.2-7.6]). An additional four atypical patients were identified at 1 year but did not fulfil criteria for PSP or MSA. INTERPRETATION Our results suggest that the true prevalence of PSP and MSA has been underestimated, since many patients in the community remain undiagnosed or misdiagnosed.

Abstract
BACKGROUND In Europe and North America, Parkinson's disease is the major form of parkinsonism; less than 4% of cases are progressive supranuclear palsy (PSP) and about 20% are atypical parkinsonism. The distribution of these subgroups is different in the French West Indies. We aimed to define the clinical and demographic specificity of these disorders in Guadeloupe and to investigate a postulated link with consumption of herbal tea and fruits from the Annonaceae family (Annona muricata and Annona squamosa), which contain neurotoxic benzyltetrahydroisoquinoline alkaloids. METHODS Between September, 1996, and August, 1998, 87 consecutive patients with parkinsonism were referred to the single neurological department in Guadeloupe. After detailed clinical, neurophysiological, cognitive, and neuroradiological assessment, they were classified by generally accepted criteria as having Parkinson's disease, PSP, or atypical parkinsonism. We compared the amount of tropical fruits and herbal tea consumed by the various parkinsonian subgroups and by frequency-matched controls (patients with benign symptoms and no neurodegenerative disease). FINDINGS Of the 87 patients, 22 had Parkinson's disease, 31 had PSP, 30 had atypical parkinsonism, and four had atypical parkinsonism associated with motor neuron disease, 44 of the patients with PSP or atypical parkinsonism were male. The patients with atypical parkinsonism had symmetrical rigidity and bradykinesia, and no levodopa peak-dose dyskinesias. Patients with PSP differed from those with atypical parkinsonism because they had supranuclear vertical down-gaze palsy, severe gait and balance problems, and frontal-lobe syndrome. 29 patients with PSP reported regular consumption of pawpaw fruit, and 26 drank herbal tea. 30 patients with atypical parkinsonism reported regular consumption of pawpaw fruit, and 24 drank herbal tea. Both of these groups consumed significantly more fruit and herbal tea than patients with Parkinson's disease (fruit: odds ratio 23.6; herbal tea: 28.2); and controls (fruit: 20.7; herbal tea: 6.48). INTERPRETATION Our study confirms the over-representation of atypical parkinsonism and PSP in patients with parkinsonism in the French West Indies. Chronic exposure to neurotoxic alkaloids could be an important aetiological factor because these compounds induce parkinsonism in animals. A larger epidemiological study, to clarify the link between these fruits with atypical parkinsonism and PSP, is proposed.
