Motor Score (motor + score)
Kinds of Motor Score Selected AbstractsImpact of Huntington's disease on quality of lifeMOVEMENT DISORDERS, Issue 2 2001D.I. Helder MA Abstract The purpose of this study was to systematically assess the impact of Huntington's disease (HD) on patients' health-related quality of life (QOL). Seventy-seven patients with a clinically confirmed diagnosis of HD were interviewed by means of the Sickness Impact Profile (SIP). Additional data were gathered on patients' motor performance by means of the motor section of the Unified Huntington Disease Rating Scale (UHDRS), and cognitive performance by means of the Mini-Mental State (MMS). Patients had high scores on the SIP subscales, indicating moderate to severe functional impairment. Total Motor Score (TMS), MMS scores, and the duration of HD were significantly correlated with patients' scores on the SIP, and predicted a significant amount of variance of the Physical Dimension of the SIP, but not of the Psychosocial Dimension. We conclude that HD has a great impact on patients' physical and psychosocial well-being, the latter being more severely affected. Implications for further research and clinical practice are discussed. © 2001 Movement Disorder Society. [source] Disease progression of human SOD1 (G93A) transgenic ALS model ratsJOURNAL OF NEUROSCIENCE RESEARCH, Issue 1 2006Arifumi Matsumoto Abstract The recent development of a rat model of amyotrophic lateral sclerosis (ALS) in which the rats harbor a mutated human SOD1 (G93A) gene has greatly expanded the range of potential experiments, because the rats' large size permits biochemical analyses and therapeutic trials, such as the intrathecal injection of new drugs and stem cell transplantation. The precise nature of this disease model remains unclear. We described three disease phenotypes: the forelimb-, hindlimb-, and general-types. We also established a simple, non-invasive, and objective evaluation system using the body weight, inclined plane test, cage activity, automated motion analysis system (SCANET), and righting reflex. Moreover, we created a novel scale, the Motor score, which can be used with any phenotype and does not require special apparatuses. With these methods, we uniformly and quantitatively assessed the onset, progression, and disease duration, and clearly presented the variable clinical course of this model; disease progression after the onset was more aggressive in the forelimb-type than in the hindlimb-type. More importantly, the disease stages defined by our evaluation system correlated well with the loss of spinal motor neurons. In particular, the onset of muscle weakness coincided with the loss of approximately 50% of spinal motor neurons. This study should provide a valuable tool for future experiments to test potential ALS therapies. © 2005 Wiley-Liss, Inc. [source] Double-blind study of pardoprunox, a new partial dopamine agonist, in early Parkinson's disease,MOVEMENT DISORDERS, Issue 6 2010Juliana Bronzova MD Abstract This study examined the efficacy and safety of the partial dopamine agonist, pardoprunox (SLV308), in the treatment of patients with early Parkinson's disease (PD). Patients were randomized to receive pardoprunox (n = 69) or placebo (n = 70). Pardoprunox was titrated to each patient's optimal dose (9,45 mg/d) over 2 to 6 weeks and then maintained at this dose for a further 3 weeks. Concomitant anti-Parkinson treatment was not permitted. In the primary analysis, Unified PD Rating Scale (UPDRS)-Motor score was improved in pardoprunox-treated patients (overall mean dose 23.8 mg/d; ,7.3 points), as compared with placebo (,3.0 points; P = 0.0001), from baseline to end point. At end point, there were more responders (,30% reduction in UPDRS-Motor score) in the pardoprunox group (50.7%) than in the placebo group (15.7%; P < 0.0001). In other secondary analyses, UPDRS-activities of daily living (ADL) and -ADL+Motor scores were also significantly more improved in the pardoprunox group. Nausea was reported by 32 of 68 (47.1%) pardoprunox-treated patients (vs. 3/70, 4.3%, placebo-treated patients), with dizziness, somnolence, headache, and asthenia also reported by ,10 patients. In this exploratory proof-of-concept study, pardoprunox significantly improved motor function in patients with early PD. The efficacy and safety profile of pardoprunox justifies its further investigation in PD. © 2010 Movement Disorder Society [source] Chronic bilateral subthalamic deep brain stimulation in a patient with homozygous deletion in the Parkin geneMOVEMENT DISORDERS, Issue 12 2004Marianna Capecci MD Abstract Chronic subthalamic nucleus deep brain stimulation (STN-DBS) is an efficacious treatment for idiopathic Parkinson's disease (PD) that cannot be further improved by medical therapy. We present a case of an individual with juvenile parkinsonism caused by homozygous deletion of exon 3 in the parkin gene with disabling long-term side-effects from levodopa who underwent bilateral STN neuromodulation. Parkin-linked parkinsonism may show clinical features different from sporadic PD, yet it shares levodopa responsiveness. Because levodopa responsiveness is a predictor of STN-DBS efficacy, we argued that this kind of surgical approach might be efficacious in hereditary parkin-linked juvenile parkinsonism. We evaluated clinical and functional assessment before and 12 months after surgery. The results showed that the Unified Parkinson Disease Rating Scales Motor score improved by 84% in our patient, the levodopa equivalent daily dose medication (LEDD) was reduced by 66%, and, finally, disabling and severe dyskinesias disappeared. © 2004 Movement Disorder Society [source] A pilot study using nabilone for symptomatic treatment in Huntington's disease,MOVEMENT DISORDERS, Issue 15 2009Adrienne Curtis BSC Abstract Pilot study of nabilone in Huntington's disease (HD). Double-blind, placebo-controlled, cross-over study of nabilone versus placebo. Primary outcome, Unified Huntington's Disease Rating Scale (UHDRS) total motor score. Secondary measures: UHDRS subsections for chorea, cognition and behavior, and neuropsychiatric inventory (NPI). 44 randomized patients received either nabilone (1 or 2 mg) followed by placebo (n = 22), or placebo followed by nabilone (n = 22). Recruiting was straightforward. Nabilone safe and well tolerated, no psychotic episodes. Assessment of either dose of nabilone versus placebo showed a treatment difference of 0.86 (95% CI: ,1.8 to 3.52) for total motor score; 1.68 (95% CI: 0.44 to 2.92) for chorea; 3.57 (95% CI: ,3.41 to 10.55) for UHDRS cognition; 4.01 (95% CI: ,0.11 to 8.13) for UHDRS behavior, and 6.43 (95% CI: 0.2 to 12.66) for the NPI. Larger longer RCT of nabilone in HD is feasible and warranted. © 2009 Movement Disorder Society [source] Progression of dysprosody in Parkinson's disease over time,A longitudinal study,MOVEMENT DISORDERS, Issue 5 2009Sabine Skodda MD Abstract Parkinsonian speech or hypokinetic dysarthria results from a multidimensional impairment of phonation, articulation, and prosody. Although the dysprosody in Parkinson's disease (PD) is well described (alterations in speech rate and pause time, speech intensity and pitch variation), little is known about alterations of these single prosodic parameters over a longer time course. The objective of this study is to analyze changes of speech rate and pitch variation in patients with PD over time and to compare these findings with healthy controls. Patients with PD (N = 50; 27 male and 23 female) and n = 50 age-matched healthy controls (25 male, 25 female) were tested and retested after at least 7 months (mean: 25.02; median: 21; SD: 17.44; range: 7,79 months). In the PD group, motor impairment according to UPDRS motor score was similar at first and second visit. The participants had to accomplish a standardized four sentence reading task. The acoustical analysis was performed using a standard head-worn microphone for voice recordings and commercial audio software (WaveLab®). For the determination of intonation based upon fundamental frequency (F0) variation, we used a computer analysis program (Praat®). Articulatory velocity was determined by measurement of syllable rate and pause ratios. In the PD group, total speech rate (syllables per second related to total speech time/TSR) and net speech rate declined from first to second examination, especially in the male patients, but showed no significant differences to the control group. The course of pitch variation revealed some gender particularities. Whereas female patients' pitch variability declined over time, male patients' intonation variability remained relatively stable. F0 variation in male and female patients with PD were significantly reduced compared with the control group in the first examination and the follow up as well. Progression of prosodic impairment over time showed no correlation to disease duration or UPDRS motor score. Some aspects of dysprosody in PD show characteristic changes over time, but show no clear correlation with general motor impairment as assessed by UPDRS motor score. Therefore, we suspect that the underlying mechanism could be independent from dopaminergic deficits. © 2008 Movement Disorder Society [source] Replacement of dopaminergic medication with subthalamic nucleus stimulation in Parkinson's disease: Long-term observation,MOVEMENT DISORDERS, Issue 4 2009Luigi M. Romito MD Abstract Stimulation of the subthalamic nucleus (STN) is an effective treatment for advanced Parkinson's disease (PD), but the medication requirements after implant are poorly known. We performed a long-term prospective evaluation of 20 patients maintained at stable dopaminergic therapy for 5 years after bilateral STN implants, who were evaluated 6 months, 1 year, 3 years, and 5 years after surgery. We measured, during the entire observation period, the effect of deep brain stimulation on motor and functional outcome measures, the levodopa equivalent daily dose and the total electrical energy delivered. At 5 years, the UPDRS motor score had improved by 54.2% and levodopa equivalent dose was reduced by 61.9%, compared with preimplant. Dopaminergic medication remained stable during the observation period, but energy was progressively increased over time. Rest tremor, rigidity, gait, lower and upper limb akinesia, and total axial score were improved in decreasing order. Postural stability and speech improved transiently, whereas on-period freezing of gait, motor fluctuations and dyskinesias recovered durably. Functional measures did not show improvement in autonomy and daily living activities after STN implant. Chronic STN stimulation allows to replace for dopaminergic medications in the long-term at the expense of an increase of the total energy delivered. This is associated with marked improvement of motor features without a matching benefit in functional measures. © 2008 Movement Disorder Society [source] Two-year follow-up on the effect of unilateral subthalamic deep brain stimulation in highly asymmetric Parkinson's disease,MOVEMENT DISORDERS, Issue 3 2009Han-Joon Kim MD Abstract Although bilateral subthalamic deep brain stimulation (STN DBS) provides greater relief from the symptoms of Parkinson's disease (PD) than unilateral STN DBS, it has been suggested that unilateral STN DBS may be a reasonable treatment option in selected patients, especially those with highly asymmetric PD. In previous studies on the effect of unilateral STN DBS, the asymmetry of PD symptoms was not prominent and the mean follow-up durations were only 3 to 12 months. In this study, we report our findings in a series of 8 patients with highly asymmetric PD who were treated with unilateral STN DBS and were followed for 24 months. Serial changes in Unified Parkinson's Disease Rating Scale (UPDRS) motor score and subscores in the ipsilateral, contralateral, and axial body parts were analyzed. Unilateral STN DBS improved the UPDRS motor score and the contralateral subscore in the on -medication state for 5 nonfluctuating patients and in the off -medication state for 3 fluctuating patients. However, the ipsilateral subscore progressively worsened and reversed asymmetry became difficult to manage, which led to compromised medication and stimulator adjustment. At 24 months, all the patients were considering the second-side surgery. Our results suggest that bilateral STN DBS should be considered even in highly asymmetric PD. © 2008 Movement Disorder Society [source] Bilateral deep brain stimulation of the globus pallidus internus in tardive dystonia,MOVEMENT DISORDERS, Issue 13 2008Wataru Sako MD Abstract Tardive dystonia is a disabling movement disorder as a consequence of exposure to neuroleptic drugs. We followed 6 patients with medically refractory tardive dystonia treated by bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) for 21 ± 18 months. At last follow-up, the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) motor score improved by 86% ± 14%, and the BFMDRS disability score improved by 80% ± 12%. Bilateral GPi-DBS is a beneficial therapeutic option for the long-term relief of tardive dystonia. © 2008 Movement Disorder Society [source] Long-term follow-up of impulse control disorders in Parkinson's diseaseMOVEMENT DISORDERS, Issue 1 2008Eugenia Mamikonyan MS Abstract Recent studies have linked dopamine agonist (DA) usage with the development of impulse control disorders (ICDs) in Parkinson's disease (PD). Little is known about optimal management strategies or the long-term outcomes of affected patients. To report on the clinical interventions and long-term outcomes of PD patients who developed an ICD after DA initiation. Subjects contacted by telephone for a follow-up interview after a mean time period of 29.2 months. They were administered a modified Minnesota Impulse Disorder Interview for compulsive buying, gambling, and sexuality, and also self-rated changes in their ICD symptomatology. Baseline and follow-up dopamine replacement therapy use was recorded and verified by chart review. Of 18 subjects, 15 (83.3%) participated in the follow-up interview. At follow-up, patients were receiving a significantly lower DA levodopa equivalent daily dosage (LEDD) (Z = ,3.1, P = 0.002) and a higher daily levodopa dosage (Z = ,1.9, P = 0.05), but a similar total LEDD dosage (Z = ,0.47, P = 0.64) with no changes in Unified Parkinson's Disease Rating Scale motor score (Z = ,1.3, P = 0.19). As part of ICD management, 12 (80.0%) patients discontinued or significantly decreased DA treatment, all of whom experienced full or partial remission of ICD symptoms by self-report, and 10 (83.3%) of whom no longer met diagnostic criteria for an ICD. For PD patients who develop an ICD in the context of DA treatment, discontinuing or significantly decreasing DA exposure, even when offset by an increase in levodopa treatment, is associated with remission of or significant reduction in ICD behaviors without worsening in motor symptoms. © 2007 Movement Disorder Society [source] Memory and executive function impairment predict dementia in Parkinson's diseaseMOVEMENT DISORDERS, Issue 6 2002Gilberto Levy MD Abstract We analyzed the association of neuropsychological test impairment at baseline with the development of dementia in idiopathic Parkinson's disease (PD) patients. A cohort of nondemented PD patients from northern Manhattan, NY was followed annually with neurological and neuropsychological evaluations. The neuropsychological battery included tests of verbal and nonverbal memory, orientation, visuospatial ability, language, and abstract reasoning. The association of baseline neuropsychological tests scores with incident dementia was analyzed using Cox proportional hazards models. The analysis controlled for age, gender, education, duration of PD, and the total Unified Parkinson's Disease Rating Scale motor score at baseline. Forty-five out of 164 patients (27%) became demented during a mean follow-up of 3.7 ± 2.3 years. Four neuropsychological test scores were significantly associated with incident dementia in the Cox model: total immediate recall (RR: 0.92, 95% CI: 0.87,0.97, P = 0.001) and delayed recall (RR: 0.73, 95% CI: 0.59,0.91, P = 0.005) of the Selective Reminding Test (SRT), letter fluency (RR: 0.87, 95% CI: 0.77,0.99, P = 0.03), and Identities and Oddities of the Mattis Dementia Rating Scale (RR: 0.85, 95% CI: 0.73,0.98, P = 0.03). When the analysis was performed excluding patients with a clinical dementia rating of 0.5 (questionable dementia) at baseline evaluation, total immediate recall and delayed recall were still predictive of dementia in PD. Our results indicate that impairment in verbal memory and executive function are associated with the development of dementia in patients with PD. © 2002 Movement Disorder Society [source] Randomized controlled trial of intraputamenal glial cell line,derived neurotrophic factor infusion in Parkinson diseaseANNALS OF NEUROLOGY, Issue 3 2006Anthony E. Lang MD Objective Glial cell line,derived neurotrophic factor (GDNF) exerts potent trophic influence on midbrain dopaminergic neurons. This randomized controlled clinical trial was designed to confirm initial clinical benefits observed in a small, open-label trial using intraputamenal (Ipu) infusion of recombinant human GDNF (liatermin). Methods Thirty-four PD patients were randomized 1 to 1 to receive bilateral continuous Ipu infusion of liatermin 15,g/putamen/day or placebo. The primary end point was the change in Unified Parkinson Disease Rating Scale (UPDRS) motor score in the practically defined off condition at 6 months. Secondary end points included other UPDRS scores, motor tests, dyskinesia ratings, patient diaries, and 18F-dopa uptake. Results At 6 months, mean percentage changes in "off" UPDRS motor score were ,10.0% and ,4.5% in the liatermin and placebo groups, respectively. This treatment difference was not significant (95% confidence interval, ,23.0 to 12.0, p = 0.53). Secondary end point results were similar between the groups. A 32.5% treatment difference favoring liatermin in mean 18F-dopa influx constant (p = 0.019) was observed. Serious, device-related adverse events required surgical repositioning of catheters in two patients and removal of devices in another. Neutralizing antiliatermin antibodies were detected in three patients (one on-study and two in the open-label extension). Interpretation Liatermin did not confer the predetermined level of clinical benefit to patients with PD despite increased 18F-dopa uptake. It is uncertain whether technical differences between this trial and positive open-label studies contributed in any way this negative outcome. Ann Neurol 2006 [source] How much phenotypic variation can be attributed to parkin genotype?ANNALS OF NEUROLOGY, Issue 2 2003Ebba Lohmann MD To establish phenotype,genotype correlations in early-onset parkinsonism, we have compared the phenotype of a large series of 146 patients with and 250 patients without parkin mutations. Although no single sign distinguished the groups, patients with mutations had significantly earlier and more symmetrical onset, dystonia more often at onset and hyperreflexia, slower progression of the disease, and a tendency toward a greater response to levodopa despite lower doses. After forward stepwise multiple logistic regression analysis, dystonia at onset and brisk reflexes were not longer significantly different but were correlated with age at onset rather than the presence of the parkin mutation. Age at onset in carriers of parkin mutations varied as did the rate of progression of the disease: the younger the age at onset the slower the evolution. The genotype influenced the phenotype: carriers of at least one missense mutation had a higher United Parkinson's Disease Rating Scale motor score than those carrying two truncating mutations. The localization of the mutations was also important because missense mutations in functional domains of parkin resulted in earlier onset. Patients with a single heterozygous mutation had significantly later and more asymmetrical onset and more frequent levodopa-induced fluctuations and dystonia than patients with two mutations. Ann Neurol 2003 [source] Asymmetrical lateral ventricular enlargement in Parkinson's diseaseEUROPEAN JOURNAL OF NEUROLOGY, Issue 4 2009M. M. Lewis Background:, A recent case report suggested the presence of asymmetrical lateral ventricular enlargement associated with motor asymmetry in Parkinson's disease (PD). The current study explored these associations further. Methods:, Magnetic resonance imaging (3T) scans were obtained on 17 PD and 15 healthy control subjects at baseline and 12,43 months later. Baseline and longitudinal lateral ventricular volumetric changes were compared between contralateral and ipsilateral ventricles in PD subjects relative to symptom onset side and in controls relative to their dominant hand. Correlations between changes in ventricular volume and United Parkinson's disease rating scale motor scores (UPDRS-III) whilst on medication were determined. Results:, The lateral ventricle contralateral to symptom onset side displayed a faster rate of enlargement compared to the ipsilateral (P = 0.004) in PD subjects, with no such asymmetry detected (P = 0.312) in controls. There was a positive correlation between ventricular enlargement and worsening motor function assessed by UPDRS-III scores (r = 0.96, P < 0.001). Discussion:, There is asymmetrical lateral ventricular enlargement that is associated with PD motor asymmetry and progression. Further studies are warranted to investigate the underlying mechanism(s), as well as the potential of using volumetric measurements as a marker for PD progression. [source] Chronic high dose transdermal nicotine in Parkinson's disease: an open trialEUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2007G. Villafane Whether nicotine has therapeutic effects on Parkinson's disease (PD) symptoms is controversial, but high doses and chronic treatment have never been tested. We report the results of a pilot, open-label trial to assess the safety and possible efficacy of chronic high doses of nicotine. Six patients with advanced idiopathic PD received increasing daily doses of transdermal nicotine up to 105 mg/day over 17 weeks. All patients but one accepted the target dose. Nausea and vomiting were frequent but moderate, and occurred in most of the patients (four of six) who received over 90 mg/day and 14 weeks of nicotine treatment. During the plateau phase, patients improved their motor scores and dopaminergic treatment was reduced. These results confirm the feasibility of chronic high dose nicotinic treatment in PD but warrant validation of the beneficial effects by a randomized controlled trial. [source] Does ageing influence deep brain stimulation outcomes in Parkinson's disease?MOVEMENT DISORDERS, Issue 10 2007Fabienne Ory-Magne MD Abstract We sought to define the influence of ageing in clinical, cognitive, and quality-of-life outcomes after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD). We performed motor assessment (UPDRS), mood tests, cognitive, and quality of life evaluation (PDQ-39) on PD patients before surgery, and 12 and 24 months after, and we recorded adverse events. The variations of these parameters after surgery were correlated with age using regression statistical tests. Cerebral bleeding risk was evaluated by a nonparametric test. We enrolled 45 patients (mean age 60 ± 9 years, range 40,73). No significant correlation was found between age and motor scores and PDQ-39 improvements at 12 months. At 24 months, there was a significant negative correlation between age and the improvement of three dimensions of PDQ 39 (mobility, activities of daily life, and cognition). Cognitive impairment showed no correlation, but apathy and depression were positively correlated with age. Significant statistical difference was observed between cerebral bleeding and age. STN-DBS is an effective treatment for elderly patients with advanced PD. A longer follow-up duration and a larger population seem necessary to better assess the quality of life perception in elderly patients and to determinate the real risk of hemorrage. © 2007 Movement Disorder Society [source] [123I] FP-CIT spect study in vascular parkinsonism and Parkinson's diseaseMOVEMENT DISORDERS, Issue 9 2007Jan Zijlmans MD Abstract There is substantial evidence to support a role for small vessel disease (SVD) as a cause for vascular parkinsonism (VP). Using [123I] FP-CIT SPECT (single photon emission computed tomography), we have tried to determine whether VP patients have pre-synaptic dopaminergic function similar to PD patients, and whether the severity of parkinsonian symptoms as well as the levodopa response in VP patients are correlated with pre-synaptic dopaminergic dysfunction. Thirteen patients fulfilling operational clinical criteria for VP had [123I] FP-CIT scans. Mean [123I] FP-CIT uptake in the basal ganglia was significantly lower in VP patients than in healthy controls, and the asymmetry index was not significantly different between these groups. In contrast, compared with the PD group, only the mean asymmetry index was significantly lower in VP patients. None of the parameters measured was significantly different between VP patients who had an insidious onset of parkinsonism (VPi) and those who had an acute onset (VPa). There was a significant correlation between the bilateral basal ganglia FP-CIT uptake reduction in the VP patients and UPDRS motor scores, but not with the mean % reduction in motor UPDRS after levodopa. We suggest that in the majority of VP patients, pre-synaptic dopaminergic function is reduced. The presence of a rather symmetrical FP-CIT uptake in the basal ganglia may help to distinguish VP from PD and could therefore be used as a criterion for the clinical diagnosis of VP. © 2007 Movement Disorder Society [source] Open-label pilot study of levetiracetam (Keppra) for the treatment of chorea in Huntington's diseaseMOVEMENT DISORDERS, Issue 11 2006FAAN, Theresa A. Zesiewicz MD Abstract The objective of this study is to evaluate the tolerability and preliminary efficacy of levetiracetam (LEV) in reducing chorea in Huntington's disease (HD) patients in a prospective open-label pilot study. Nine HD patients with chorea were treated with LEV in doses up to 3,000 mg/day for up to 48 days. The primary endpoint measure was the Unified Huntington's Disease Rating Scale (UHDRS) chorea subscore. The mean dose (±SD) of LEV at endpoint was 2,583.3 ± 1,020.6 mg/day. Mean UHDRS chorea score decreased from 12.6 ± 3.0 at baseline to 6.7 ± 4.3 at endpoint (P = 0.01). There was no significant change in UHDRS total motor scores (38.8 ± 11.4 at baseline and 33.6 ± 26.7 at endpoint; P = 0.24). Somnolence contributed to a 33% drop-out rate, and 3 patients developed Parkinsonism. Results of this open label study suggest that LEV may be efficacious in reducing chorea in HD patients. © 2006 Movement Disorder Society [source] Health-related quality of life in multiple system atrophyMOVEMENT DISORDERS, Issue 6 2006Anette Schrag MD Abstract Although multiple system atrophy (MSA) is a neurodegenerative disorder leading to progressive disability and decreased life expectancy, little is known about patients' own evaluation of their illness and factors associated with poor health-related quality of life (Hr-QoL). We, therefore, assessed Hr-QoL and its determinants in MSA. The following scales were applied to 115 patients in the European MSA-Study Group (EMSA-SG) Natural History Study: Medical Outcome Study Short Form (SF-36), EQ-5D, Beck Depression Inventory (BDI), Mini-Mental state examination (MMSE), Unified MSA Rating Scale (UMSARS), Hoehn & Yahr (H&Y) Parkinson's disease staging scale, Composite Autonomic Symptom Scale (COMPASS), and Parkinson's Disease Sleep Scale (PDSS). Forty-six percent of patients had moderate to severe depression (BDI , 17); Hr-QoL scores on the SF-36 and EQ-5D were significantly impaired. Pain, the only domain with similar scores in MSA and published PD patients, was reported more frequently in patients with MSA-P (predominantly parkinsonian motor subtype) than MSA-C (predominantly cerebellar motor subtype; 76% vs. 50%; P = 0.005). Hr-QoL scores correlated most strongly with UMSARS motor, COMPASS, and BDI scores but not with MMSE scores, age at onset, or disease duration. The COMPASS and UMSARS activities of daily living scores were moderate-to-strong predictors for the SF-36 physical summary score and the BDI and UMSARS motor scores for the SF-36 mental summary score. This report is the first study to show that Hr-QoL is significantly impaired in MSA. Although not all possible factors related to impaired Hr-QoL in MSA could be assessed, autonomic dysfunction, motor impairment, and depression were most closely associated with poor Hr-QoL, and therapeutic management, therefore, should concentrate upon these aspects of the disease. © 2006 Movement Disorder Society [source] Olanzapine treatment for dopaminergic-induced hallucinationsMOVEMENT DISORDERS, Issue 5 2002William G. Ondo MD Abstract Atypical antipsychotic medications with lower affinities for D2 receptors are considered useful alternatives to treat drug-induced hallucinations in Parkinson's disease (PD). We conducted a double-blind, placebo-controlled, unforced titration, parallel design study (2:1 drug to placebo randomization ratio) using olanzapine (2.5,10 mg/day to effect) in 30 PD patients with drug-induced hallucinations. We performed an extensive battery of neuropsychological tests, the Unified Parkinson's Disease Rating Scale (UPDRS), assessments of on and off time at baseline and at 9 weeks after starting the medication. Sixteen patients on olanzapine (mean dose, 4.6 mg/night) and 11 on placebo completed the study. Compared with placebo, performance on the UPDRS item 2 (thought disorder), and a structured interview for hallucinations, both tended to improve on drug but neither reached statistical significance. A neuropsychological test battery did not show any significant differences. Total on UPDRS motor scores (P < 0.05) and timed tapping (P < 0.01) worsened while on drug compared to placebo. Bradykinesia (P < 0.01) and gait (P < 0.001) items on the UPDRS largely accounted for this deterioration. After completion of the study, 8 of 16 patients randomly assigned to drug continued olanzapine at a mean dose of 2.4 mg/day. However, at the last recorded visit only 5 of 24 (20.8%) of all patients exposed to drug (including those originally randomly assigned to placebo) remained on olanzapine. In patients with PD, low-dose olanzapine did not significantly improve hallucinations but did worsen motor function. © 2002 Movement Disorder Society [source] Divergence of Fine and Gross Motor Skills in Prelingually Deaf Children: Implications for Cochlear Implantation,THE LARYNGOSCOPE, Issue 8 2006David L. Horn MD Abstract Objective: The objective of this study was to assess relations between fine and gross motor development and spoken language processing skills in pediatric cochlear implant users. Study Design: The authors conducted a retrospective analysis of longitudinal data. Methods: Prelingually deaf children who received a cochlear implant before age 5 and had no known developmental delay or cognitive impairment were included in the study. Fine and gross motor development were assessed before implantation using the Vineland Adaptive Behavioral Scales, a standardized parental report of adaptive behavior. Fine and gross motor scores reflected a given child's motor functioning with respect to a normative sample of typically developing, normal-hearing children. Relations between these preimplant scores and postimplant spoken language outcomes were assessed. Results: In general, gross motor scores were found to be positively related to chronologic age, whereas the opposite trend was observed for fine motor scores. Fine motor scores were more strongly correlated with postimplant expressive and receptive language scores than gross motor scores. Conclusions: Our findings suggest a disassociation between fine and gross motor development in prelingually deaf children: fine motor skills, in contrast to gross motor skills, tend to be delayed as the prelingually deaf children get older. These findings provide new knowledge about the links between motor and spoken language development and suggest that auditory deprivation may lead to atypical development of certain motor and language skills that share common cortical processing resources. [source] Initiating levodopa/carbidopa therapy with and without entacapone in early Parkinson disease: The STRIDE-PD studyANNALS OF NEUROLOGY, Issue 1 2010Fabrizio Stocchi MD Objective L-dopa is the most widely used and most effective therapy for Parkinson disease (PD), but chronic treatment is associated with motor complications in the majority of patients. It has been hypothesized that providing more continuous delivery of L-dopa to the brain would reduce the risk of motor complications, and that this might be accomplished by combining L-dopa with entacapone, an inhibitor of catechol-O-methyltransferase, to extend its elimination half-life. Methods We performed a prospective 134-week double-blind trial comparing the risk of developing dyskinesia in 747 PD patients randomized to initiate L-dopa therapy with L-dopa/carbidopa (LC) or L-dopa/carbidopa/entacapone (LCE), administered 4× daily at 3.5-hour intervals. The primary endpoint was time to onset of dyskinesia. Results In comparison to LC, patients receiving LCE had a shorter time to onset of dyskinesia (hazard ratio, 1.29; p = 0.04) and increased frequency at week 134 (42% vs 32%; p = 0.02). These effects were more pronounced in patients receiving dopamine agonists at baseline. Time to wearing off and motor scores were not significantly different, but trended in favor of LCE treatment. Patients in the LCE group received greater L-dopa dose equivalents than LC-treated patients (p < 0.001). Interpretation Initiating L-dopa therapy with LCE failed to delay the time of onset or reduce the frequency of dyskinesia compared to LC. In fact, LCE was associated with a shorter time to onset and increased frequency of dyskinesia compared to LC. These results may reflect that the treatment protocol employed did not provide continuous L-dopa availability and the higher L-dopa dose equivalents in the LCE group. ANN NEUROL 2010;68:18,27 [source] Clock drawing from the occupational therapy adult perceptual screening test: Its correlation with demographic and clinical factors in the stroke populationAUSTRALIAN OCCUPATIONAL THERAPY JOURNAL, Issue 3 2010Deirdre M. Cooke Background/aim:,The aim of this study was to explore the relationships between clock drawing ability following stroke, and key clinical variables including cognition, functional independence, side and type of stroke, educational level and age. Methods:,One hundred and ninety-seven people with stroke were recruited from 12 hospital and rehabilitation facilities. The participants' scores from the Clock Drawing Test in the Occupational Therapy Adult Perceptual Screening Test were the dependent variables and were entered into logistic regression with Functional Independence Measure motor scores, side of stroke, Oxfordshire Classification System of Stroke, educational level and age as independent variables. Correlation with the Mini-Mental State Examination was analysed independently, due to its strong correlation with other variables. Results:,The Mini-Mental State Examination correlated significantly with the Clock Drawing Test ( Exp (B) = 0.826, P < 0.001). In the multivariate analysis, a significant relationship was found with age (Exp ( B) = 1.052, P < 0.001), Functional Independence Measure , motor (Exp (B) = 0.984, P = 0.030) and side of stroke (Exp (B) = 0.384, P = 0.003). Age demonstrated the strongest correlation with the Clock Drawing Test ability and the greatest decline was from approximately 70 years of age. Conclusions:,The Clock Drawing Test may be a useful and quick screen of cognitive impairments following stroke. Age-related decline must be considered and it is essential that clinicians use this only as a strategy to determine whether a more comprehensive assessment is required. [source] | ||||||||||
