All cases examined postmortem at the Mayo Clinic that met the classic neuropathological criteria for progressive supranuclear palsy PSP were identified for retrospective clinical analyses.
The necropsy material was re-examined by a second neuropathologist to confirm the pathological diagnosis of PSP, yielding 12 cases. A range of clinical signs were documented in these patients, with numerous findings beyond those noted in the original descriptions of this disorder.
Atypical clinical findings included absence of supranuclear gaze palsy two cases , prominent asymmetry two , arm dystonia two , upper limb apraxia two , myoclonus two , chorea one , eyelid opening apraxia one , and respiratory disturbance one. A definite clinical diagnosis of PSP had been made during life in only eight of the 12 patients.
From the retrospective analysis of these 12 cases, a set of clinical criteria were developed for the premortem diagnosis of PSP emphasising differences from other akinetic-rigid disorders. Two patients with "pure akinesia" who showed the characteristic changes of progressive supranuclear palsy PSP at necropsy are described. They had akinesia but no rigidity or tremor, and ophthalmoplegia was not observed during the course of illness. The symptoms of "pure akinesia" was not improved by levodopa therapy but was considerably improved by L-threo-3,4-dihydroxy-phenylserine.
At necropsy, pathological findings were not different from those reported for PSP. It is suggested that "pure akinesia" is an atypical manifestation of PSP, and that norepinephrinergic neurons may be involved in some types of PSP. Therapeutic advances in multiple system atrophy and progressive supranuclear palsy. Multiple system atrophy MSA and progressive supranuclear palsy PSP are relentlessly progressive neurodegenerative diseases leading to severe disability and ultimately death within less than 10 y.
Despite increasing efforts in basic and clinical research, effective therapies for these atypical parkinsonian disorders are lacking. Although earlier small clinical studies in MSA and PSP mainly focused on symptomatic treatment, advances in the understanding of the molecular underpinnings of these diseases and in the search for biomarkers have paved the way for the first large and well-designed clinical trials aiming at disease modification.
All of these failed to demonstrate signal efficacy with regard to the primary outcome measures. In addition, two randomized, placebo-controlled, double-blind trials have studied the efficacy of droxidopa in the symptomatic treatment of neurogenic orthostatic hypotension, including patients with MSA, with positive results in one trial. This review summarizes the design and the outcomes of these and other smaller trials published since and attempts to highlight priority areas of future therapeutic research in MSA and PSP.
Advancing functional dysconnectivity and atrophy in progressive supranuclear palsy. Progressive supranuclear palsy syndrome PSP-S results from neurodegeneration within a network of brainstem, subcortical, frontal and parietal cortical brain regions. It is unclear how network dysfunction progresses and relates to longitudinal atrophy and clinical decline. At baseline, voxel based morphometry VBM revealed that patients with mild-to-moderate clinical symptoms showed structural atrophy in subcortex and brainstem, prefrontal cortex PFC; supplementary motor area, paracingulate, dorsal and ventral medial PFC , and parietal cortex precuneus.
In healthy controls, this network contained a medial parietal module, a prefrontal-paralimbic module, and a subcortical-brainstem module. Longitudinally, patients with PSP-S had declining intermodular FC between the subcortical-brainstem and parietal modules, while progressive atrophy was observed in subcortical-brainstem regions midbrain, pallidum and posterior frontal perirolandic cortex. This suggested that later-stage subcortical-posterior cortical change may follow an earlier-stage subcortical-anterior cortical disease process.
Clinically, patients with more severe baseline impairment showed greater subsequent prefrontal-parietal cortical FC declines and posterior frontal atrophy rates, while patients with more rapid longitudinal clinical decline showed coupled prefrontal-paralimbic FC decline. Meaning in life in patients with progressive supranuclear palsy. This exploratory study investigated meaning in life MiL in patients with progressive supranuclear palsy PSP.
PHF paired helical filaments antibody identifies p-tau in both normal and pathological conditions and AT8 recognizes p-tau characteristic of pathological conditions.
Differences between the three groups were assessed by quantification of immunopositive areas in the epidermis. These data suggest that the skin reflects brain pathology. Impaired perception of surface tilt in progressive supranuclear palsy. Geoffrey; Schoneburg, Bernadette M. Introduction Progressive supranuclear palsy PSP is characterized by early postural instability and backward falls. The mechanisms underlying backward postural instability in PSP are not understood.
The aim of this study was to test the hypothesis that postural instability in PSP is a result of dysfunction in the perception of postural verticality. Objective tests of postural impairment included: Subjects with PSP, PD and normal controls accurately perceived the direction of gravity when standing on a tilting surface.
Unlike PD and control subjects, subjects with PSP exerted less postural corrective torque in response to toes up surface tilts. Discussion Difficulty perceiving backward tilt of the surface or body may account for backward falls and postural impairments in patients with PSP. These observations suggest that abnormal central integration of sensory inputs for perception of body and surface orientation contributes to the pathophysiology of postural instability in PSP.
Widespread spinal cord involvement in progressive supranuclear palsy. We describe the histopathologic features of spinal cord lesions in 10 cases of progressive supranuclear palsy PSP and review the literature.
Histologic examination revealed atrophy with myelin pallor in the anterior funiculus and anterolateral funiculus in the cervical and thoracic segments in eight of the 10 cases, whereas the posterior funiculus was well preserved. The degrees of atrophy of the anterior funiculus and the anterolateral funiculus correlated with that of the tegmentum of the medulla oblongata. Myelin pallor of the lateral corticospinal tract was observed in two of the 10 cases. Microscopic observation of the spinal white matter, particularly the cervical segment, revealed a few to several neuropil threads, particularly in the white matter surrounding the anterior horn after Gallyas-Braak GB staining or AT-8 tau immunostaining.
However, the posterior funiculus was completely preserved from the presence of argyrophilic or tau-positive structures. In the spinal gray matter, widespread distribution of neurons with cytoplasmic inclusions and neuropil threads was observed, particularly in the medial division of the anterior horn and intermediate gray matter, especially in the cervical segment.
Globose-type neurofibrillary tangles and pretangles were found. The distribution of GB- or AT-8 tau-positive small neurons and neuropil threads resembled that of the spinal interneurons. In conclusion, the spinal cord, especially the cervical segment, is constantly involved in the pathologic process of PSP. We speculate that spinal interneurons and their neuronal processes, particularly in the medial division of the anterior horn and intermediate gray matter of the cervical segment, are most severely damaged in the PSP spinal cord.
Which ante mortem clinical features predict progressive supranuclear palsy pathology? Progressive supranuclear palsy PSP is a neuropathologically defined disease presenting with a broad spectrum of clinical phenotypes. To identify clinical features and investigations that predict or exclude PSP pathology during life, aiming at an optimization of the clinical diagnostic criteria for PSP.
We performed a systematic review of the literature published since to identify clinical features and investigations that may predict or exclude PSP pathology. We then extracted standardized data from clinical charts of patients with pathologically diagnosed PSP and relevant disease controls and calculated the sensitivity, specificity, and positive predictive value of key clinical features for PSP in this cohort.
Of articles identified by the database inquiry, met predefined standards. The literature review identified clinical features predictive of PSP, including features of the following 4 functional domains: No biomarker or genetic feature was found reliably validated to predict definite PSP. High-quality original natural history data were available from patients with pathologically diagnosed PSP and from pathologically diagnosed disease controls 54 corticobasal degeneration, 51 multiple system atrophy with predominant parkinsonism, 53 Parkinson's disease, 73 behavioral variant frontotemporal dementia.
We identified clinical features that predicted PSP pathology, including phenotypes other than Richardson's syndrome, with varying sensitivity and specificity. Our results highlight the clinical variability of PSP and the high prevalence of phenotypes other than Richardson's syndrome.
The features of variant phenotypes with high specificity and sensitivity should serve to optimize clinical diagnosis of PSP. Lipoperoxidation is selectively involved in progressive supranuclear palsy. Progressive supranuclear palsy PSP is a neurodegenerative disorder characterized by extensive neurofibrillary tangle NFT formation and neuronal loss in selective neuronal populations. Currently, no clues to the biological events underlying the pathological process have emerged.
The presence and the amount of lipid and protein oxidation markers, as well as of pyrraline and pentosidine. The levels of 4-hydroxynonenal HNE and thiobarbituric acid reactive substances TBARS , 2 major products of lipid peroxidation, were significantly increased by 1. Carlton; Bergman, Ira; Malatack, J.
Jeffrey; Zitelli, Basil J. A 7-year-old girl with progressive ataxia, spasticity, supranuclear ophthalmoplegia, and sea-blue histiocytes in her bone marrow underwent orthotopic liver transplantation for hepatocellular carcinoma. After an initial period of stabilization, she has shown progression of neurologic symptoms with recurrence of storage material in the transplanted liver.
Role of the tau gene region chromosome inversion in progressive supranuclear palsy, corticobasal degeneration, and related disorders. An inverted region on chromosome 17 has been previously linked to many Pick complex diseases.
Due to the inversion, an exact causal locus has been difficult to identify, but the microtubule-associated protein tau gene is a likely candidate gene for its involvement in these diseases with tau inclusion.
To search for variants that confer susceptibility to 4 tauopathies and clinically related disorders. A total of samples were genotyped from an unrelated white population of patients with progressive supranuclear palsy PSP , corticobasal degeneration CBD , frontotemporal dementia, and frontotemporal dementia with amyotrophy.
Unaffected individuals from the same population were used as controls. The results from an inverted region of chromosome 17 that contains the MAPT gene.
Genotypes of cases and controls were compared using a Fisher exact test on a marker-by-marker basis. Haplotypes were determined by visually inspecting genotypes. Comparing any particular disease and controls, the association was constant across the inverted chromosome segment.
As expected, the markers are highly correlated and the association is seen across the entire region, which makes it difficult to narrow down a disease-causing variant or even a possible candidate gene. However, considering the pathologic abnormalities of these diseases and the involvement of tau mutations seen in familial forms, the MAPT gene represents the most likely cause driving the association.
The ability to assess the distribution and extent of tau pathology in Alzheimer's disease and progressive supranuclear palsy in vivo would help to develop biomarkers for these tauopathies and clinical trials of disease-modifying therapies. New radioligands for positron emission tomography have generated considerable interest, and controversy, in their potential as tau biomarkers. We assessed the radiotracer 18F-AV with positron emission tomography imaging to compare the distribution and intensity of tau pathology in 15 patients with Alzheimer's pathology including amyloid-positive mild cognitive impairment , 19 patients with progressive supranuclear palsy, and 13 age- and sex-matched controls.
Regional analysis of variance and a support vector machine were used to compare and discriminate the clinical groups, respectively. We also examined the 18F-AV autoradiographic binding in post-mortem tissue from patients with Alzheimer's disease, progressive supranuclear palsy, and a control case to assess the 18F-AV binding specificity to Alzheimer's and non-Alzheimer's tau pathology.
Corticobasal degeneration with olivopontocerebellar atrophy and TDP pathology: CBD is a disorder affecting cognition and movement due to a progressive neurodegeneration associated with distinctive neuropathologic features, including abnormal phosphorylated tau protein in neurons and glia in cortex, basal ganglia, diencephalon and brainstem, as well as ballooned neurons and astrocytic plaques.
Two patients had clinical features suggestive of progressive supranuclear palsy PSP , and the third case had cerebellar ataxia thought to be due to idiopathic OPCA. Corticobasal degeneration CBD is a disorder affecting cognition and movement due to a progressive neurodegeneration associated with distinctive neuropathologic features, including abnormal phosphorylated tau protein in neurons and glia in cortex, basal ganglia, diencephalon, and brainstem, as well as ballooned neurons and astrocytic plaques.
Progression of white matter damage in progressive supranuclear palsy with predominant parkinsonism. Progression of brain structural damage in these patients remains unknown. At study entry, patients were compared with 36 healthy controls.
Voxelwise statistical analysis of white matter DT MRI data mean, axial and radial diffusivity, and fractional anisotropy was carried out using tract-based spatial statistics. No WM changes were detected in cerebellar WM. Background and Purpose This case report describes the effects of long-term year participation in a community exercise program for a client with mixed features of corticobasal degeneration CBD and progressive supranuclear palsy PSP.
The effects of exercise participation on both functional status and brain volume are described. Case Description A year-old male dentist initially reported changes in gait and limb coordination. At age 70 years, the client began a therapist-led community group exercise program for people with Parkinson disease PD. The program included trunk and lower extremity stretching and strengthening, upright balance and strengthening, and both forward and backward treadmill walking.
The client participated twice weekly for 1 hour for 10 years and was reassessed in years 9 to Outcomes Falls self-reported weekly over the year period of the study by the client and his wife decreased from 1.
Balance, walking endurance, and general mobility declined slightly. Gait speed both comfortable and fast declined; the client was unable to vary gait speed. Quantitative brain measurements indicated a slow rate of whole brain volume loss and ventricular expansion compared with clients with autopsy-proven CBD or PSP.
Discussion This client has participated consistently in a regular group exercise program for 10 years. He has reduced fall frequency, maintained balance and endurance, and retained community ambulation using a walker. Combined with the slow rate of brain volume loss, this evidence supports the efficacy of a regular exercise program to prolong longevity and maintain function in people with CBD or PSP.
This case attests to the occult nature of this rare and devastating syndrome. Progranulin gene GRN mutations are characterized by heterogeneous presentations. Plasma progranulin levels were evaluated in 34 patients, including 19 with PSPS, 12 with CBS, and 3 with mixed signs, with the purpose to screen for the presence of causal mutations, associated with low levels.
We found undetectable levels in a patient with CBS. Sequencing confirmed the presence of the Thrfs deletion. Completed suicide in a case of clinically diagnosed progressive supranuclear palsy. We present the clinical history and the cognitive and behavioral presentations of a male patient with suspected progressive supranuclear palsy PSP who fatally shot himself in the head.
We believe his act of suicide was the consequence of impulsivity, rather than primary depression or mood disturbance. In cases of suspected PSP and other atypical parkinsonisms, health professionals must be aware of neurobehavioral risk factors for suicide attempts and completions to promote patient safety; however, the literature on this topic is sparse.
Our case highlights the potentially lethal consequences of impulsivity and other neuropsychiatric symptoms in PSP and related syndromes. Tideglusib reduces progression of brain atrophy in progressive supranuclear palsy in a randomized trial. It is believed that glycogen synthase kinase-3 hyperphosphorylates tau protein in progressive supranuclear palsy PSP. For the magnetic resonance imaging MRI substudy reported here, we assessed the progression of brain atrophy.
TAUROS was a multinational, phase 2, double-blind, placebo-controlled trial in patients with mild-to-moderate PSP who were treated with oral tideglusib mg or mg daily or with placebo for 1 year. A subset of patients underwent baseline and week MRI. Automated, observer-independent, atlas-based, and mask-based volumetry was done on high-resolution, T1-weighted, three-dimensional data. For primary outcomes, progression of atrophy was compared both globally brain, cerebrum and regionally third ventricle, midbrain, pons between the active and placebo groups Bonferroni correction.
The groups compared well in their demographic characteristics. Clinical results showed no effect of tideglusib over placebo. A trend toward reduced atrophy also was observed in the frontal lobe, hippocampus, caudate nucleus, midbrain, and brainstem. In patients with PSP, tideglusib reduced the progression of atrophy in the whole brain, particularly in the parietal and occipital lobes. Different decision deficits impair response inhibition in progressive supranuclear palsy and Parkinson's disease.
Progressive supranuclear palsy and Parkinson's disease have distinct underlying neuropathology, but both diseases affect cognitive function in addition to causing a movement disorder.
They impair response inhibition and may lead to impulsivity, which can occur even in the presence of profound akinesia and rigidity. The current study examined the mechanisms of cognitive impairments underlying disinhibition, using horizontal saccadic latencies that obviate the impact of limb slowness on executing response decisions. Participants were cued on each trial to make a pro-saccade to a horizontal target or withhold their responses.
Both patient groups had impaired behavioural performance, with more commission errors than controls. Mean saccadic latencies were similar between all three groups. We analysed behavioural responses as a binary decision between Go and No-Go choices. By using Bayesian parameter estimation, we fitted a hierarchical drift-diffusion model to individual participants' single trial data.
The model decomposes saccadic latencies into parameters for the decision process: In a leave-one-out three-way classification analysis, the model parameters provided better discrimination between patients and controls than raw behavioural measures. Both patient groups had slower drift rate of accumulation, and shorter non-decision time than controls. But patients with progressive supranuclear palsy were strongly biased towards a pro-saccade decision boundary compared to Parkinson's patients and controls.
This indicates a prepotency of. The aim of this study was to compare the patterns of grey and white matter atrophy on MRI in autopsy confirmed progressive supranuclear palsy PSP and corticobasal degeneration CBD , and to determine whether the patterns vary depending on the clinical syndrome.
PSP and CBD subjects were also subdivided into those with a dominant dementia or extrapyramidal syndrome. PSP subjects showed brainstem atrophy with involvement of the cortex and underlying white matter. Frontoparietal grey and subcortical grey matter atrophy occurred in CBD. When subdivided, PSP subjects with an extrapyramidal syndrome had more brainstem atrophy and less cortical atrophy than CBD subjects with an extrapyramidal syndrome. PSP subjects with a dementia syndrome had more subcortical white matter atrophy than CBD subjects with a dementia syndrome.
Differentiating Parkinson disease PD from progressive supranuclear palsy PSP can be challenging early in the clinical course. The aim of our study was to see if specific retinal changes could serve as a distinguishing feature. We used spectral domain optical coherence tomography SD-OCT with automatic segmentation to measure peripapillary nerve fiber layer thickness and the thickness and volume of retinal layers at the macula.
Thicknesses of superior peripapillary retinal nerve fiber layer pRNFL , macular ganglion cell layer, inner plexiform layer, inner nuclear layer, and macular volume were more affected in PSP compared with PD P Influence of orbital eye position on vertical saccades in progressive supranuclear palsy.
Schneider, Rosalyn; Chen, Athena L. Disturbance of vertical saccadesis a cardinal feature of progressive supranuclear palsy PSP. We investigated whether the amplitude and peak velocity of saccades is affected by the orbital position fromwhich movements start in PSP patients and age-matched control subjects. All patients showed some effect of starting eye position, whether beginning in the upward or downward field of gaze, on saccade amplitude, peak velocity PV , and net range of movement.
Generally, reduction of amplitude and PV were commensurate and bidirectional in the affected hemifield of gaze. Such findings are unlikelyto be due to orbital factors and could be explained by varying degrees of involvement of rostral midbrain nucleiin the pathological process.
Tracking brain damage in progressive supranuclear palsy: In this prospective, longitudinal, multiparametric MRI study, we investigated clinical as well as brain grey matter and white matter WM regional changes in patients with progressive supranuclear palsy-Richardson's syndrome PSP-RS. Twenty-one patients with PSP-RS were evaluated at baseline relative to 36 healthy controls and after a mean follow-up of 1. Relative to controls, patients with PSP-RS showed at baseline a typical pattern of brain damage, including midbrain atrophy, frontal cortical thinning and widespread WM involvement of the main infratentorial and supratentorial tracts that exceeded cortical damage.
Longitudinal study showed that PSP-RS exhibited no further changes in cortical thinning, which remained relatively focal, while midbrain atrophy and WM damage significantly progressed. Corpus callosum and frontal WM tract changes correlated with the progression of both disease severity and behavioural dysfunction.
This study demonstrated the feasibility of carrying out longitudinal diffusion tensor MRI in patients with PSP-RS and its sensitivity to identifying the progression of pathology. No commercial use is permitted unless otherwise expressly granted. Richard; Williamson, David; Jones, P. Objective We tested whether in vivo neuroinflammation relates to the distinctive distributions of pathology in Alzheimer disease AD and progressive supranuclear palsy PSP.
Methods Sixteen patients with symptomatic AD including amnestic mild cognitive impairment with amyloid-positive PET scan , 16 patients with PSP—Richardson syndrome, and 13 age-, sex-, and education-matched healthy controls were included in this case-control study. Results [11C]PK binding in the medial temporal lobe and occipital, temporal, and parietal cortices was increased in patients with AD, relative both to patients with PSP and to controls.
Conclusions Together, our results suggest that neuroinflammation has an important pathogenic role in the 2 very different human neurodegenerative disorders of AD and PSP. The increase and distribution of microglial activation suggest that immunotherapeutic strategies may be useful in slowing the progression of both diseases. Background Two recent randomized, placebo-controlled trials of putative disease-modifying agents davunetide, tideglusib in progressive supranuclear palsy PSP failed to show efficacy, but generated data relevant for future trials.
Methods We provide sample size calculations based on data collected in PSP patients assigned to placebo in these trials. A placebo effect was calculated. A placebo effect was not detected in these scales. Conclusions We propose the 1-year PSP-Rating Scale score change as the single primary readout in clinical neuroprotective or disease-modifying trials.
To date, pharmacological treatment options for progressive supranuclear palsy PSP , a neurodegenerative tauopathy, are limited. The MAO-B inhibitor rasagiline has shown neuroprotective effects in preclinical models of neurodegeneration. To evaluate the safety, tolerability and therapeutic effect of rasagiline on symptom progression in PSP. Of the 44 patients randomized, 26 completed the trial per protocol.
Rasagiline was well tolerated, with a slight increase of known side effects hallucinations, ventricular extrasystoles. Symptom progression averaged at No difference was seen in SEADL, depression, cognitive function, frontal executive function and posturographic measurements.
Post hoc analyses of PSP-RS subdomains indicate a potential beneficial effect in the "limb motor" subdomain, whereas performance appeared lower in the "mentation" and "history" subdomains in the treatment group.
While rasagiline is well tolerated in PSP, a beneficial effect on overall symptom progression was not detected. Post hoc analyses suggest the implementation of more specific endpoints in future studies. Disruption of spatial organization and interjoint coordination in Parkinson's disease, progressive supranuclear palsy, and multiple system atrophy.
Patients with basal ganglia diseases may exhibit ideomotor apraxia. To define the nature of the impairment of the action production system, we studied a repetitive gesture of slicing bread by three-dimensional computergraphic analysis in eight nondemented patients with Parkinson's disease in the "on" state, five with progressive supranuclear palsy and four with multiple system atrophy.
Two patients with Parkinson's disease and two with progressive supranuclear palsy showed ideomotor apraxia for transitive movements on standard testing. A Selspott II system was used for kinematic analysis of wrist trajectories and angular motions of the shoulder and elbow joints.
Spatial disruption of wrist trajectories was more severe in patients with ideomotor apraxia. We posit that the basal ganglia are part of the parallel parieto-frontal circuits devoted to sensorimotor integration for object-oriented behavior. The severity and characteristics of spatial abnormalities of a transitive movement would therefore depend on the location and distribution of the pathologic process within these circuits.
Automatic classification of patients with idiopathic Parkinson's disease and progressive supranuclear palsy using diffusion MRI datasets. Parkinsonian syndromes encompass a spectrum of neurodegenerative diseases, which can be classified into various subtypes. The differentiation of these subtypes is typically conducted based on clinical criteria.
The aim of this study is to present an image-based classification method of patients with Parkinson's disease PD and patients with progressive supranuclear palsy PSP , an atypical variant of PD.
Therefore, apparent diffusion coefficient ADC parameter maps were calculated based on diffusion-tensor magnetic resonance imaging MRI datasets. Mean ADC values were determined in 82 brain regions using an atlas-based approach. The extracted mean ADC values for each patient were then used as features for classification using a linear kernel support vector machine classifier.
To increase the classification accuracy, a feature selection was performed, which resulted in the top 17 attributes to be used as the final input features.
In conclusion, the classification of PD and PSP patients based on ADC features obtained from diffusion MRI datasets is a promising new approach for the differentiation of Parkinsonian syndromes in the broader context of decision support systems. Retinal degeneration in progressive supranuclear palsy measured by optical coherence tomography and scanning laser polarimetry.
This cross-sectional study compared the retinal morphology between patients with progressive supranuclear palsy PSP and healthy controls. The macular volume and the thickness of the majority of macular sectors were reduced compared to controls. PSP seems to be associated with reduced thickness and volume of the macula and reduction of the RNFL, independent of disease duration or severity. Speech disorders reflect differing pathophysiology in Parkinson's disease, progressive supranuclear palsy and multiple system atrophy.
Although speech disorder is frequently an early and prominent clinical feature of Parkinson's disease PD as well as atypical parkinsonian syndromes APS such as progressive supranuclear palsy PSP and multiple system atrophy MSA , there is a lack of objective and quantitative evidence to verify whether any specific speech characteristics allow differentiation between PD, PSP and MSA. The accurate differential diagnosis of dysarthria subtypes was based on the quantitative acoustic analysis of 16 speech dimensions.
Whilst PD speakers manifested pure hypokinetic dysarthria, ataxic components were more affected in MSA whilst PSP subjects demonstrated severe deficits in hypokinetic and spastic elements of dysarthria. Dysarthria in PSP was dominated by increased dysfluency, decreased slow rate, inappropriate silences, deficits in vowel articulation and harsh voice quality whereas MSA by pitch fluctuations, excess intensity variations, prolonged phonemes, vocal tremor and strained-strangled voice quality.
Thus, motor speech examination may provide useful information in the evaluation of these diseases with similar manifestations. Effects of robot assisted gait training in progressive supranuclear palsy PSP: Progressive supranuclear palsy PSP is a rare neurodegenerative disease clinically characterized by prominent axial extrapyramidal motor symptoms with frequent falls. Over the last years the introduction of robotic technologies to recover lower limb function has been greatly employed in the rehabilitative practice.
This observational trial is aimed at investigating the changes in the main spatiotemporal following end-effector robot training in people with PSP. Five cognitively intact participants with PSP and gait disorders. Patients were submitted to a rehabilitative program of robot-assisted walking sessions for 45 min, 5 times a week for 4 weeks. The spatiotemporal parameters at the beginning T0 and at the end of treatment T1 were recorded by a gait analysis laboratory.
Robot training was feasible, acceptable and safe and all participants completed the prescribed training sessions. All patients showed an improvement in the gait spatiotemporal index Mean velocity, Cadence, Step length, and Step width T0 vs.
Robot training is a feasible and safe form of rehabilitation for cognitively intact people with PSP. The lack of side effects and the positive results in the gait parameter index in all patients support the recommendation to extend the trials of this treatment.
Further investigation regarding the effectiveness of robot training in time is necessary. Clinicopathological studies over the last decade have broadened the clinical spectrum of progressive supranuclear palsy PSP to include several distinct clinical syndromes.
These differences correspond with variations in pathological profiles reported in the literature. Blink reflex recovery cycle to differentiate Progressive Supranuclear Palsy from Cortico-basal syndrome. Progressive Supranuclear Palsy PSP and Cortico-basal syndrome CBS may share similar clinical findings and peculiar tests to distinguish between the two disorders could be useful.
Supervised machine learning has been proposed as a revolutionary approach for identifying sensitive medical image biomarkers or combination of them allowing for automatic diagnosis of individual subjects.
The aim of this work was to assess the feasibility of a supervised machine learning algorithm for the assisted diagnosis of patients with clinically diagnosed Parkinson's disease PD and Progressive Supranuclear Palsy PSP. Morphological T1-weighted Magnetic Resonance Images MRIs of PD patients 28 , PSP patients 28 and healthy control subjects 28 were used by a supervised machine learning algorithm based on the combination of Principal Components Analysis as feature extraction technique and on Support Vector Machines as classification algorithm.
Voxels influencing classification between PD and PSP patients involved midbrain, pons, corpus callosum and thalamus, four critical regions known to be strongly involved in the pathophysiological mechanisms of PSP. Classification accuracy of individual PSP patients was consistent with previous manual morphological metrics and with other supervised machine learning application to MRI data, whereas accuracy in the detection of individual PD patients was significantly higher with our classification method.
The algorithm provides excellent discrimination of PD patients from PSP patients at an individual level, thus encouraging the application of computer-based diagnosis in clinical practice.
