- Background: Non-motor symptoms are present in Parkinson's disease (PD) and a key determinant of quality of life. The Non-motor Symptoms Scale (NMSS) is a validated scale that allows quantifying frequency and severity (burden) of NMS. We report a proposal for using NMSS scores to determine levels of NMS burden (NMSB) and to complete PD patient classification. Methods: This was an observational, cross-sectional international study of 935 consecutive patients. Using a distribution of NMSS scores by quartiles, a classification based on levels from 0 (no NMSB at all) to 4 (very severe NMSB) was obtained and its relation with Hoehn and Yahr (HY) staging, motor and health-related quality of life scales was analyzed. Concordance between NMSB levels and grouping based on clinician's global impression of severity, using categorical regression, was determined. Disability and HRQoL predictors were identified by multiple regression models. Results: The distribution of motor and QoL scales scores by HY and NMSB levels was significantly discriminative. The difference in the classification of cases for both methods, HY and NMSB, was significant (gamma = 0.45; ASE = 0.032). Concordance between NMSB and global severity-based levels from categorical regression was 91.8%, (kappa(w) = 0.97). NMS score was predictor of disability and QoL. Conclusions: Current clinical practice does not address a need for inclusion of non-motor scores in routine assessment of PD in spite of the overwhelming influence of NMS on disability and quality of life. Our data overcome the problems of "pure motor assessment'' and we propose a combined approach with addition of NMSB levels to standard motor assessments.

- Non-motor symptoms (NMS) of Parkinson's disease remain the most under-appreciated and under-researched when taken as a whole. Data is emerging that it is the "totaL" burden of NMS that is the major determinant of quality of life not a single NMS such as depression for instance. Only recently validated tools such as the NMSQuest which empowers patients to declare NMS and the NMS scale, the SCOPA scales, and the modified version of the MDS-UPDRS have become available and validated for bedside clinical assessment of NMS. For the first time clinical trials have been incorporating non-motor measures as outcome measures and clinical recommendations for treatment of non-motor symptoms of PD are being published. This review aims to address some of these topical and "real life" aspects of modern day management of Parkinson's. (C) 2011 Published by Elsevier Ltd.

- Motor complications impair quality of life and cause severe disability in patients with advanced Parkinson's disease (PD). Since they are often refractory to medical therapy, interventional therapies have been developed, which can provide a considerable reduction of daily off-time and dopaminergic dyskinesias. Continuous dopaminergic drug delivery (CDD) is based on the steady stimulation of striatal dopamine receptors by subcutaneous apomorphine or duodenal l-DOPA infusions via portable minipumps. Advances in the understanding of basal ganglia functioning and in neurosurgical, electrophysiological and neuroimaging techniques have led to a renaissance of neurosurgery for advanced PD. Deep brain stimulation of the subthalamic nucleus (STN-DBS) is the most invasive procedure promising great benefit and the highest level of independency for suitable patients, but is definitely associated with surgical risks and DBS-related side effects. Each of these more or less invasive therapy options has its own profile, and a thorough consideration of its advantages and drawbacks for the individual situation is mandatory. In this paper, we summarize relevant facts for this decision and provide some guidelines for a responsible counseling of eligible patients.

- Differences in the expression of non-motor symptoms (NMS) by Parkinson's disease (PD) patients may have important implications for their management and prognosis. Gender is a basic epidemiological variable that could influence such expression. The present study evaluated the prevalence and severity of NMS by gender in an international sample of 951 PD patients, 62.63% males, using the non-motor symptoms scale (NMSS). Assessments for motor impairment and complications, global severity, and health state were also applied. All disease stages were included. No significant gender differences were found for demographic and clinical characteristics. For the entire sample, the most prevalent symptoms were Nocturia (64.88%) and Fatigue (62.78%) and the most prevalent affected domains were Sleep/Fatigue (84.02%) and Miscellaneous (82.44%). Fatigue, feelings of nervousness, feelings of sadness, constipation, restless legs, and pain were more common and severe in women. On the contrary, daytime sleepiness, dribbling saliva, interest in sex, and problems having sex were more prevalent and severe in men. Regarding the NMSS domains, Mood/Apathy and Miscellaneous problems (pain, loss of taste or smell, weight change, and excessive sweating) were predominantly affected in women and Sexual dysfunction in men. No other significant differences by gender were observed. To conclude, in this study significant differences between men and women in prevalence and severity of fatigue, mood, sexual and digestive problems, pain, restless legs, and daytime sleepiness were found. Gender-related patterns of NMS involvement may be relevant for clinical trials in PD.

- ABSTRACT: Seventeen patients with advanced Parkinson disease (PD) were treated with intrajejunal L-dopa infusion (IJL) and compared with a matched group of 9 patients (termed comparator [C]) not given IJL because of funding restriction by primary care trusts (PCTs) in the UK, although considered to be clinically eligible for IJL. Assessments were baseline and follow-up (6 months) with Hoehn and Yahr staging, unified PD rating scale (UPDRS-III and UPDRS-IV), Parkinson disease questionnaire (PDQ-8, quality of life [QoL]) and nonmotor symptom scale (NMSS).Baseline characteristics were comparable between the groups. The IJL-treated group showed highly significant improvements in UPDRS-III (P = 0.005), UPDRS-IV (P = 0.0004), total NMSS score (P = 0.004), and QoL (P = 0.01), whereas the C group showed no change in these parameters. A large effect size of IJL was seen in treated patients for UPDRS-III (1.13), UPDRS-IV (1.52), NMSS score (0.82), and QoL (1.12), whereas continuing conventional treatment registered no effect in C.This study confirms the robust effect of IJL on motor and, in particular, nonmotor symptoms and QoL in advanced PD as described in open-label studies but additionally points to the need for such treatment in those denied this therapy because of centrally dictated funding policies leading to inequalities in health care.

- Test sequences in a test battery for Parkinson's disease patients, consisting of self-assessments and motor tests, were carried out repeatedly in a telemedicine setting, during week-long test periods and results were summarized in an 'overall score'. 35 patients in stable and fluctuating conditions (15 age- and gender-matched pairs) used the test battery for 1 week, and were then assessed with UPDRS and PDQ-39. This procedure was repeated 1 week later, without treatment changes. Reliability was assessed by intraclass correlation coefficients and Cronbach's alpha. Convergent validity was assessed by Spearman rank correlations and known-groups' validity, by the Mann-Whitney test. According to anonymous usability questionnaires, the patients could easily complete the tasks. Median compliance (93%) and test-retest reliability (0.88) were good. The correlations between overall score and total UPDRS (-0.64) and PDQ-39 (-0.72) were adequate. Median overall score was 18% better in the stable compared to the fluctuating group (p = 0.0014).
