    (2024) PARMERA, Jacy Bezerra; CARNEIRO, Camila de Godoi; ALMEIDA, Isabel Junqueira de; OLIVEIRA, Marcos Castello Barbosa de; BARBOSA, Pedro Melo; STUDART-NETO, Adalberto; ONO, Carla Rachel; NITRINI, Ricardo; BUCHPIGUEL, Carlos Alberto; BARBOSA, Egberto Reis; BRUCKI, Sonia Maria Dozzi; COUTINHO, Artur Martins
    BackgroundCorticobasal syndrome (CBS) is associated with diverse underlying pathologies, including the four-repeat (4R)-tauopathies. The Movement Disorders Society (MDS) criteria for progressive supranuclear palsy (PSP) proposed the novel category ""probable 4R-tauopathy"" to address the phenotypic overlap between PSP and corticobasal degeneration (CBD).ObjectivesTo investigate the clinical ability of the MDS-PSP criteria for probable 4R-tauopathy in predicting a negative amyloid-PET in CBS. Additionally, this study aims to explore CBS patients classified as 4R-tauopathy concerning their clinical features and neuroimaging degeneration patterns.MethodsThirty-two patients with probable CBS were prospectively evaluated and split into those who fulfilled or did not fulfill the 4R-tauopathy criteria (CBS-4RT+ vs. CBS-4RT-). All patients underwent positron emission tomographies (PET) with [18F]fluorodeoxyglucose and [11C]Pittsburgh Compound-B (PIB) on a hybrid PET-MRI scanner to perform multimodal quantitative comparisons with a control group.ResultsEleven patients were clinically classified as CBS-4RT+, and only one had a positive PIB-PET. The CBS-4RT+ classification had 92% specificity, 52% sensitivity, and 69% accuracy in predicting a negative PIB-PET. The CBS-4RT+ group presented with dysarthria and perseveration more often than the CBS-4RT- group. Moreover, the CBS-4RT+ group showed a prominent frontal hypometabolism extending to the supplementary motor area and striatum, and brain atrophy at the anterior cingulate and bilateral striata.ConclusionsThe 4R-tauopathy criteria were highly specific in predicting a negative amyloid-PET in CBS. Patients classified as 4R-tauopathy presented distinct clinical aspects, as well as brain metabolism and atrophy patterns previously associated with tauopathies.

    Association of autonomic symptoms with disease progression and survival in progressive supranuclear palsy
    (2019) OLIVEIRA, Marcos C. B.; LING, Helen; LEES, Andrew J.; HOLTON, Janice L.; PABLO-FERNANDEZ, Eduardo De; WARNER, Thomas T.
    Background Development of autonomic failure is associated with more rapid disease course and shorter survival in patients with Parkinson's disease and multiple system atrophy. However, autonomic symptoms have not been specifically assessed as a prognostic factor in progressive supranuclear palsy (PSP). We evaluated whether development of autonomic symptoms is associated with disease progression and survival in PSP. Methods A retrospective review of clinical data from consecutive patients with autopsy-confirmed PSP from the Queen Square Brain Bank between January 2012 and November 2016 was performed. Time from disease onset to four autonomic symptoms (constipation, urinary symptoms, erectile dysfunction and orthostatic hypotension) were noted. Time from diagnosis to five disease milestones and survival were calculated to assess disease progression, and their risk was estimated through a Cox proportional hazards model. Results A total of 103 PSP patients were included. Urinary symptoms and constipation were present in 81% and 71% of cases, respectively. Early development of constipation and urinary symptoms were associated with higher risk of reaching the first disease milestone (respectively, HR: 0.88; 95% CI 0.83 to 0.92; p< 0.001; and HR: 0.80; 95% CI 0.75 to 0.86; p< 0.001) and with a shorter survival in these patients (respectively, HR: 0.73; 95% CI 0.64 to 0.84; p< 0.001; and HR: 0.88; 95% CI 0.80 to 0.96; p= 0.004). On multivariate analysis, Richardson syndrome phenotype was the other variable independently associated with shorter survival. Conclusions E arlier urinary symptoms and constipation are associated with a more rapid disease progression and reduced survival in patients with PSP.

    Progressive supranuclear palsy and corticobasal degeneration: novel clinical concepts and advances in biomarkers
    (2022) PARMERA, Jacy Bezerra; OLIVEIRA, Marcos Castello Barbosa de; RODRIGUES, Roberta Diehl; COUTINHO, Artur Martins
    Background: Progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are sporadic adult-onset primary tauopathies clinically classified among the atypical parkinsonian syndromes. They are intrinsically related with regard to their clinical features, pathology, biochemistry, and genetic risk factors. Objectives: This review highlights the current knowledge on PSP and CBD, focusing on evolving clinical concepts, new diagnostic criteria, and advances in biomarkers. Methods: We performed a non-systematic literature review through the PubMed database. The search was restricted to articles written in English, published from 1964 to date. Results: Clinicopathologic and in vivo biomarkers studies have broadened PSP and CBD clinical phenotypes. They are now recognized as a range of motor and behavioral syndromes associated with underlying 4R-tauopathy neuropathology. The Movement Disorders Society PSP diagnostic criteria included clinical variants apart from the classical description, increasing diagnostic sensitivity. Meanwhile, imaging biomarkers have explored the complexity of symptoms and pathological processes related to corticobasal syndrome and CBD. Conclusions: In recent years, several prospective or clinicopathologic studies have assessed clinical, radiological, and fluid biomarkers that have helped us gain a better understanding of the complexity of the 4R-tauopathies, mainly PSP and CBD.

    Identification of multiple system atrophy mimicking Parkinson's disease or progressive supranuclear palsy
    (2021) MIKI, Yasuo; TSUSHIMA, Eiki; FOTI, Sandrine C.; STRAND, Kate M.; ASI, Yasmine T.; YAMAMOTO, Adam Kenji; BETTENCOURT, Conceicao; OLIVEIRA, Marcos C. B.; PABLO-FERNANDEZ, Eduardo De; JAUNMUKTANE, Zane; LEES, Andrew J.; WAKABAYASHI, Koichi; WARNER, Thomas T.; QUINN, Niall; HOLTON, Janice L.; LING, Helen
    We studied a subset of patients with autopsy-confirmed multiple system atrophy who presented a clinical picture that closely resembled either Parkinson's disease or progressive supranuclear palsy. These mimics are not captured by the current diagnostic criteria for multiple system atrophy. Among 218 autopsy-proven multiple system atrophy cases reviewed, 177 (81.2%) were clinically diagnosed and pathologically confirmed as multiple system atrophy (i.e. typical cases), while the remaining 41 (18.8%) had received an alternative clinical diagnosis, including Parkinson's disease (i.e. Parkinson's disease mimics; n = 16) and progressive supranuclear palsy (i.e. progressive supranuclear palsy mimics; n = 17). We also reviewed the clinical records of another 105 patients with pathologically confirmed Parkinson's disease or progressive supranuclear palsy, who had received a correct final clinical diagnosis (i.e. Parkinson's disease, n = 35; progressive supranuclear palsy-Richardson syndrome, n = 35; and progressive supranuclear palsy-parkinsonism, n = 35). We investigated 12 red flag features that would support a diagnosis of multiple system atrophy according to the current diagnostic criteria. Compared with typical multiple system atrophy, Parkinson's disease mimics more frequently had a good levodopa response and visual hallucinations. Vertical gaze palsy and apraxia of eyelid opening were more commonly observed in progressive supranuclear palsy mimics. Multiple logistic regression analysis revealed an increased likelihood of having multiple system atrophy [Parkinson's disease mimic versus typical Parkinson's disease, odds ratio (OR): 8.1; progressive supranuclear palsy mimic versus typical progressive supranuclear palsy, OR: 2.3] if a patient developed any one of seven selected red flag features in the first 10 years of disease. Severe autonomic dysfunction (orthostatic hypotension and/or urinary incontinence with the need for a urinary catheter) was more frequent in clinically atypical multiple system atrophy than other parkinsonian disorders (Parkinson's disease mimic versus typical Parkinson's disease, OR: 4.1; progressive supranuclear palsy mimic versus typical progressive supranuclear palsy, OR: 8.8). The atypical multiple system atrophy cases more frequently had autonomic dysfunction within 3 years of symptom onset than the pathologically confirmed patients with Parkinson's disease or progressive supranuclear palsy (Parkinson's disease mimic versus typical Parkinson's disease, OR: 4.7; progressive supranuclear palsy mimic versus typical progressive supranuclear palsy, OR: 2.7). Using all included clinical features and 21 early clinical features within 3 years of symptom onset, we developed decision tree algorithms with combinations of clinical pointers to differentiate clinically atypical cases of multiple system atrophy from Parkinson's disease or progressive supranuclear palsy.
