Abstract: Depression is a common comorbid condition in Parkinson's disease (PD) and a major contributor to poor quality of life and disability. However, depression can be difficult to assess in patients with PD due to overlapping symptoms and difficulties in the assessment of depression in cognitively impaired patients. As several rating scales have been used to assess depression in PD (dPD), the Movement Disorder Society commissioned a task force to assess their clinimetric properties and make clinical recommendations regarding their use. A systematic literature review was conducted to explore the use of depression scales in PD and determine which scales should be selected for this review. The scales reviewed were the Beck Depression Inventory (BDI), Hamilton Depression Scale (Ham-D), Hospital Anxiety and Depression Scale (HADS), Zung Self-Rating Depression Scale (SDS), Geriatric Depression Scale (GDS), Montgomery-Asberg Depression Rating Scale (MADRS), Unified Parkinson's Disease Rating Scale (UPDRS) Part I, Cornell Scale for the Assessment of Depression in Dementia (CSDD), and the Center for Epidemiologic Studies Depression Scale (CES-D). Seven clinical researchers with clinical and research experience in the assessment of dPD were assigned to review the scales using a structured format. The most appropriate scale is dependent on the clinical or research goal. However, observer-rated scales are preferred if the study or clinical situation permits. For screening purposes, the HAM-D, BDI, HADS, MADRS, and GDS are valid in dPD. The CES-D and CSDD are alternative instruments that need validation in dPD. For measurement of severity of depressive symptoms, the Ham-D, MADRS, BDI, and SDS scales are recommended. Further studies are needed to validate the CSDD, which could be particularly useful for the assessment of severity of dPD in patients with comorbid dementia. To account for overlapping motor and nonmotor symptoms of depression, adjusted instrument cutoff scores may be needed for dPD, and scales to assess severity of motor symptoms (e.g., UPDRS) should also be included to help adjust for confounding factors. The HADS and the GDS include limited motor symptom assessment and may, therefore, be most useful in rating depression severity across a range of PD severity; however, these scales appear insensitive in severe depression. The complex and time-consuming task of developing a new scale to measure depression specifically for patients with PD is currently not warranted.

Abstract: Only in the last three decades, the restless legs syndrome (RLS) has been examined in randomized controlled trials. The Movement Disorder Society (MDS) commissioned a task force to perform an evidence-based review of the medical literature on treatment modalities used to manage patients with RLS. The task force performed a search of the published literature using electronic databases. The therapeutic efficacy of each drug was classified as being either efficacious, likely efficacious, investigational, nonefficacious, or lacking sufficient evidence to classify. Implications for clinical practice were generated based on the levels of evidence and particular features of each modality, such as adverse events. All studies were classed according to three levels of evidence. All Level-I trials were included in the efficacy tables; if no Level-I trials were available then Level-II trials were included or, in the absence of Level-II trials, Level-III studies or case series were included. Only studies published in print or online before December 31, 2006 were included. All studies published after 1996, which attempted to assess RLS augmentation, were reviewed in a separate section. The following drugs are considered efficacious for the treatment of RLS: levodopa, ropinirole, pramipexole, cabergoline, pergolide, and gabapentin. Drugs considered likely efficacious are rotigotine, bromocriptine, oxycodone, carbamazepine, valproic acid, and clonidine. Drugs that are considered investigational are dihydroergocriptine, lisuride, methadone, tramadol, clonazepam, zolpidem, amantadine, and topiramate. Magnesium, folic acid, and exercise are also considered to be investigational. Sumanirole is nonefficacious. Intravenous iron dextran is likely efficacious for the treatment of RLS secondary to end-stage renal disease and investigational in RLS subjects with normal renal function. The efficacy of oral iron is considered investigational; however, its efficacy appears to depend on the iron status of subjects. Cabergoline and pergolide (and possibly lisuride) require special monitoring due to fibrotic complications including cardiac valvulopathy. Special monitoring is required for several other medications based on clinical concerns: opioids (including, but not limited to, oxycodone, methadone and tramadol), due to possible addiction and respiratory depression, and some anticonvulsants (particularly, carbamazepine and valproic acid), due to systemic toxicities.

Abstract: Introduction. The European Multiple System Atrophy-Study Group (EMSA-SG) is an academic network comprising 23 centers across Europe and Israel that has constituted itself already in January 1999. This international forum of established experts under the guidance of the University Hospital of Innsbruck as coordinating center is supported by the 5th framework program of the European Union since March 2001 (QLK6-CT-2000-00661). Objectives. Primary goals of the network include (1) a central Registry for European multiple system atrophy (MSA) patients, (2) a decentralized DNA Bank, (3) the development and validation of the novel Unified MSA Rating Scale (UMSARS), (4) the conduction of a Natural History Study (NHS), and (5) the planning or implementation of interventional therapeutic trials. Methods. The EMSA-SG Registry is a computerized data bank localized at the coordinating centre in Innsbruck collecting diagnostic and therapeutic data of MSA patients. Blood samples of patients and controls are recruited into the DNA Bank. The UMSARS is a novel specific rating instrument that has been developed and validated by the EMSA-SG. The NHS comprises assessments of basic anthropometric data as well as a range of scales including the UMSARS, Unified Parkinson's Disease Rating Scale (UPDRS), measures of global disability, Red Flag list, MMSE (Mini Mental State Examination), quality of live measures, i.e. EuroQoL 5D (EQ-5D) and Medical Outcome Study Short Form (SF-36) as well as the Beck Depression Inventory (BDI). In a subgroup of patients dysautonomic features are recorded in detail using the Queen Square Cardiovascular Autonomic Function Test Battery, the Composite Autonomic Symptom Scale (COMPASS) and measurements of residual urinary volume. Most of these measures are repeated at 6-monthly follow up visits for a total study period of 24 months. Surrogate markers of the disease progression are identified by the EMSA-SG using magnetic resonance and diffusion weighted imaging (MRI and DWI, respectively). Results. 412 patients have been recruited into the Registry so far. Probable MSA-P was the most common diagnosis (49% of cases). 507 patients donated DNA for research. 131 patients have been recruited into the NHS. There was a rapid deterioration of the motor disorder (in particular akinesia) by 26.1% of the UMSARS II, and - to a lesser degree - of activities of daily living by 16.8% of the UMSARS I in relation to the respective baseline scores. Motor progression was associated with low motor or global disability as well as low akinesia or cerebellar subscores at baseline. Mental function did not deteriorate during this short follow up period. Conclusion. For the first time, prospective data concerning disease progression are available. Such data about the natural history and prognosis of MSA as well as surrogate markers of disease process allow planning and implementation of multi-centre phase II/III neuroprotective intervention trials within the next years more effectively. Indeed, a trial on growth hormone in MSA has just been completed, and another on minocycline will be completed by the end of this year.

Abstract: BACKGROUND: Huntington's disease (HD) is an orphan autosomal dominant neurodegenerative disorder caused by the amplification of a nucleic acids triplet repeat. It is characterised by core symptoms of chorea, progressive dementia and psychiatric manifestations such as depression, irritability, apathy and psychosis. In current clinical practice, drugs exist that seem to improve symptoms for HD patients. However, their effectiveness has not been fully measured. OBJECTIVES: To evaluate the effectiveness of the available interventions for the symptomatic treatment of HD. SEARCH STRATEGY: The search strategy developed for the Movement Disorders Group was undertaken. Cochrane Controlled Trials Register, Medline, EMBASE and Clinical Trials Database of the United States National Institute of Health were thoroughly searched up until December 2007. SELECTION CRITERIA: All randomised, double-blinded, placebo-controlled clinical trials conducted on any symptomatic therapy used for HD with at least ten participants were included. Participants should have HD clinical features and a confirmatory genetic diagnosis or a compatible family history. All disease variants and ages of disease onset were included. Cross-over studies were included. All pharmacological and non-pharmacological interventions aimed at the control of signs and symptoms associated with HD were to be selected. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed the identified trials for eligibility. In the selected trials, the assessment of their methodological quality was done according to the Cochrane Collaboration handbook, and eligible data were registered onto standardised forms. If possible, an intention-to-treat analysis was conducted. When data were not available in the original publication, the principal investigator of the trial was contacted. A meta-analysis was conducted when possible and otherwise the descriptive summary of the results was provided. The software Revman 5.0.15 was used for statistical analysis. MAIN RESULTS: 22 trials (1254 participants) were included. Nine trials had a cross-over design and 13 were conducted in parallel. Study duration ranged from 2 to 80 weeks. Various pharmacological interventions were studied, mostly, they were anti-dopaminergic drugs (n = 5), glutamate receptor antagonists (n = 5) and energy metabolites (n = 5). Only tetrabenazine showed a clear efficacy for the control of chorea. The remaining pharmacological interventions revealed no clear effectiveness. AUTHORS' CONCLUSIONS: No intervention proved to have a consistent symptomatic control in HD. Tetrabenazine is the anti-choreic drug with the best quality data available. Other symptomatic areas should be explored by well-designed randomised placebo-controlled studies.

Abstract: Anxiety syndromes are common in patients with Parkinson's disease (PD) with up to 30% suffering from panic disorder, and up to 11% from generalized anxiety disorder (GAD). Anxiety is associated with increased subjective motor symptoms, more severe gait problems, dyskinesias, freezing, and on/off fluctuations. Anxiety has a negative impact on health related quality of life and is strongly associated with depressive syndromes. Since a variety of anxiety scales have been used in PD patients, the Movement Disorder Society commissioned a task force to assess the clinimetric properties of these scales in PD. A systematic review was conducted to identify anxiety scales that have either been validated or used in patients with PD. Six anxiety rating scales were identified. These were the Beck anxiety inventory, the hospital anxiety and depression scale, the Zung self-rating anxiety scale and anxiety status inventory, the Spielberger state trait anxiety inventory, and the Hamilton anxiety rating scale. In addition, Item 5 (anxiety) of the neuropsychiatric inventory was included in the review. No scales met the criteria to be "recommended," and all scales were classified as "suggested." Essential clinimetric information is missing for all scales. Because several scales exist and have been used in PD, the task force recommends further studies of these instruments. If these studies show that the clinimetric properties of existing scales are inadequate, development of a new scale to assess anxiety in PD should be considered.

Abstract: Apathy is a common condition in Parkinson's disease (PD) and is generally defined as a lack of motivation. It is associated with more severe cognitive dysfunction and a decrease in activities of daily living (ADL) performance. Anhedonia, the inability to experience pleasure, can be a symptom of both depressive and apathetic syndromes. The Movement Disorder Society (MDS) commissioned a task force to assess the clinimetric properties of apathy and anhedonia scales in PD patients. A systematic literature review was conducted to identify scales that have either been validated or used in PD patients. Apathy scales identified for review include the Apathy Evaluation Scale (AES), the Apathy Scale (AS), the Apathy Inventory (AI), and the Lille Apathy Rating Scale (LARS). In addition, item 4 (motivation/initiative) of the Unified Parkinson's Disease Rating Scale (UPDRS) and item 7 (apathy) of the Neuropsychiatric Inventory (NPI) were included. Anhedonia scales identified for review were the Snaith-Hamilton Pleasure Scale (SHAPS) and the Chapman scales for physical and social anhedonia. Only the AS is classified as "recommended" to assess apathy in PD. Although item 4 of the UPDRS also meets the criteria to be classified as recommended, it should be considered for screening only because of the obvious limitations of a single item construct. For the assessment of anhedonia, only the SHAPS meets the criteria of "Suggested." Information on the validity of apathy and anhedonia scales is limited because of the lack of consensus on diagnostic criteria for these conditions.

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 > or = 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.
