Abstract
Mitochondrial dysfunction is involved in the pathophysiology of psychiatric and neurodegenerative disorders and can be used as a modulator and/or predictor of treatment responsiveness. Understanding the mitochondrial effects of antidepressants is important to connect mitochondria with their therapeutic and/or adverse effects. Pig brain-isolated mitochondria were used to evaluate antidepressant-induced changes in the activity of electron transport chain (ETC) complexes, monoamine oxidase (MAO), mitochondrial respiratory rate, and ATP. Bupropion, escitalopram, fluvoxamine, sertraline, paroxetine, and trazodone were tested. All tested antidepressants showed significant inhibition of complex I and IV activities at high concentrations (50 and 100 µmol/L); complex II + III activity was reduced by all antidepressants except bupropion. Complex I-linked respiration was reduced by escitalopram >> trazodone >> sertraline. Complex II-linked respiration was reduced only by bupropion. Significant positive correlations were confirmed between complex I-linked respiration and the activities of individual ETC complexes. MAO activity was inhibited by all tested antidepressants, with SSRIs causing a greater effect than trazodone and bupropion. The results indicate a probable association between the adverse effects of high doses of antidepressants and drug-induced changes in the activity of ETC complexes and the respiratory rate of mitochondria. In contrast, MAO inhibition could be linked to the antidepressant, procognitive, and neuroprotective effects of the tested antidepressants.

Abstract
Twenty-four novel compounds bearing tetrahydroacridine and N-propargyl moieties have been designed, synthesised, and evaluated in vitro for their anti-cholinesterase and anti-monoamine oxidase activities. Propargyltacrine 23 (IC50 = 21 nM) was the most potent acetylcholinesterase (AChE) inhibitor, compound 20 (IC50 = 78 nM) showed the best inhibitory human butyrylcholinesterase (hBChE) profile, and ligand 21 afforded equipotent and significant values on both ChEs (human AChE [hAChE]: IC50 = 0.095 ± 0.001 µM; hBChE: IC50 = 0.093 ± 0.003 µM). Regarding MAO inhibition, compounds 7, 15, and 25 demonstrated the highest inhibitory potential towards hMAO-B (IC50 = 163, 40, and 170 nM, respectively). In all, compounds 7, 15, 20, 21, 23, and 25 exhibiting the most balanced pharmacological profile, were submitted to permeability and cell viability tests. As a result, 7-phenoxy-N-(prop-2-yn-1-yl)-1,2,3,4-tetrahydroacridin-9-amine hydrochloride (15) has been identified as a permeable agent that shows a balanced pharmacological profile [IC50 (hAChE) = 1.472 ± 0.024 µM; IC50 (hBChE) = 0.659 ± 0.077 µM; IC50 (hMAO-B) = 40.39 ± 5.98 nM], and consequently, as a new hit-ligand that deserves further investigation, in particular in vivo analyses, as the preliminary cell viability test results reported here suggest that this is a relatively safe therapeutic agent.

Abstract
BACKGROUND Quality of life (QoL) in patients with Parkinson's disease (PD) is increasingly used as an efficacy outcome in clinical studies of PD to evaluate the impact of treatment from the patient's perspective. Studies demonstrating the treatment effect of pramipexole on QoL remain inconclusive. This study aims to evaluate the effect of pramipexole on QoL in patients with PD by conducting a systematic review and meta-analysis of existing clinical trials. METHODS A systematic literature search of PubMed, Embase and the Cochrane Library was performed from inception to 30 April 2022 to identify randomised, placebo-controlled trials of patients with idiopathic PD receiving pramipexole, who reported a change from baseline in their QoL as measured by the 39-item Parkinson's Disease Questionnaire (PDQ-39). Risk of bias was independently assessed by two reviewers using the Cochrane Collaboration's tool for bias assessment. RESULTS Of 80 eligible articles screened, six trials consisting of at least 2000 patients with early or advanced PD were included. From the synthesis of all six selected trials, a significant mean change from baseline in the PDQ-39 total score of -2.49 (95% CI, -3.43 to -1.54; p < 0.0001) was observed with pramipexole compared with placebo. A trend toward improvement in QoL was consistently observed among patients who received optimal doses of pramipexole (≥ 80% of the study population on 1.5 mg dosage), regardless of disease severity (advanced versus early) or baseline QoL levels. CONCLUSION This meta-analysis provides evidence for the potential treatment benefit of pramipexole in improving QoL in patients with PD.

Abstract
There are racial and socioeconomic disparities in the care of patients with Parkinson's disease (PD). Bellevue Hospital Center (BHC) in New York City is the oldest public hospital in the United States providing care to a multiracial, socioeconomically diverse and medically underserved population. We investigated racial and social disparities in providing care to patients with PD and related disorders at BHC compared to a NYU Langone Health, a Parkinson's Foundation Center of Excellence. Retrospective chart review of patients with diagnosis of PD or PD-related disorders evaluated at BHC or at NYU outpatient clinics from January 2012 to August 2017. 100 patients were enrolled from each site: BHC (55% men); NYU (49% men). The majority of patients at NYU were White (77%), compared to 14% at BHC; Hispanic patients comprised the majority at BHC (56%) (p < 0.001). BHC patients had more clinic visits per year compared to the NYU cohort (2.88 vs. 2.40, p = 0.001). BHC patients were less likely to self-report exercise (p = 0.047) or participation in physical therapy (p = 0.015). There were no clinically significant differences in diagnosis type, time to diagnosis, average Hoehn & Yahr or levodopa equivalent dose. Compared to a Parkinson's Foundation Center of Excellence, PD patients in a public hospital system are more racially diverse, are less likely to be insured, have higher rates of care utilization and are less likely to access necessary interventions such as physical therapy and exercise.

Abstract
Parkinson's disease (PD) results in a complex deterioration of motor behavior. Effective pharmacological or surgical treatments addressing the whole spectrum of both motor and cognitive symptoms are lacking. The cumulative functional impairment may have devastating socio-economic consequences on both patients and caregivers. Comprehensive models of care based on multidisciplinary approaches may succeed in better addressing the overall complexity of PD. Neurorehabilitation is a highly promising non-pharmacological intervention for managing PD. The scientific rationale beyond rehabilitation and its practical applicability remain to be established. In the present perspective, we aim to discuss the current evidence supporting integrated motor-cognitive and aerobic rehabilitation approaches for patients with PD while suggesting a practical framework to optimize this intervention in the next future.

Abstract
AIMS SD-1077, a selectively deuterated precursor of dopamine (DA) structurally related to L-3,4-dihydroxyphenylalanine (L-DOPA), is under development for treatment of motor symptoms of Parkinson's disease. Preclinical models have shown slower metabolism of central deuterated DA. The present study investigated the peripheral pharmacokinetics (PK), metabolism and safety of SD-1077. METHODS Plasma and urine PK of drug and metabolites and safety after a single oral 150 mg SD-1077 dose were compared to 150 mg L-DOPA, each in combination with 37.5 mg carbidopa (CD) in a double-blind, two-period, crossover study in healthy volunteers (n = 16). RESULTS Geometric least squares mean ratios (GMRs) and 90% confidence intervals (90% CI) of SD-1077 vs. L-DOPA for Cmax , AUC0-t , and AUC0-inf were 88.4 (75.9-103.1), 89.5 (84.1-95.3), and 89.6 (84.2-95.4), respectively. Systemic exposure to DA was significantly higher after SD-1077/CD compared to that after L-DOPA/CD, with GMRs (90% CI) of 1.8 (1.45-2.24; P = 0.0005) and 2.06 (1.68-2.52; P < 0.0001) for Cmax and AUC0-t and a concomitant reduction in the ratio of 3,4-dihydroxyphenylacetic acid/DA confirming slower metabolic breakdown of DA by monoamine oxidase (MAO). There were increases in systemic exposures to metabolites of catechol O-methyltransferase (COMT) reaction, 3-methoxytyramine (3-MT) and 3-O-methyldopa (3-OMD) with GMRs (90% CI) for SD-1077/CD to L-DOPA/CD for 3-MT exposure of 1.33 (1.14-1.56; P = 0.0077) and 1.66 (1.42-1.93; P < 0.0001) for Cmax and AUC0-t , respectively and GMRs (90% CI) for 3-OMD of 1.19 (1.15, 1.23; P < 0.0001) and 1.31 (1.27, 1.36; P < 0.0001) for Cmax and AUC0-t . SD-1077/CD exhibited comparable tolerability and safety to L-DOPA/CD. CONCLUSIONS SD-1077/CD demonstrated the potential to prolong exposure to central DA at comparable peripheral PK and safety to the reference L-DOPA/CD combination. A single dose of SD-1077 is safe for further clinical development in Parkinson's disease patients.

Abstract
OBJECTIVE To evaluate whether a 4-week multidisciplinary, aerobic, motor-cognitive and intensive rehabilitation treatment (MIRT) improves the quality of life (QoL) of patients with Parkinson's disease (PD), in the short-term and long-term period. METHODS This is a prospective, parallel-group, single-centre, single-blind, randomised clinical trial (ClinicalTrials.gov NCT02756676). 186 patients with PD, assigned to experimental group, underwent MIRT; conversely, 48 patients, assigned to control group, did not receive rehabilitation. Parkinson's Disease Questionnaire-39 was assessed 2 (T0), 10 (T1) and 18 (T2, only experimental group) weeks after the enrolment. We compared T1 versus T0 scores within subjects and delta scores (T1-T0) between subjects. To investigate the long-term effects, we compared T2 and T0 scores in the experimental group. RESULTS At T0, no between-group differences in the Global Index Score (GBI) were observed (experimental group: 43.6±21.4, controls: 41.6±22.9, P=0.50). At T1, we did not find significant changes in controls (delta score: 1.2±9.9, P=0.23), and we found an improvement in GBI in the experimental group (delta score: -8.3±18.0, P<0.0001), significant also between subjects (P<0.0001). Comparing T2 versus T0 in the experimental group, the GBI maintained a significant improvement (delta score: -4.8±17.5, P<0.0001). CONCLUSIONS A rehabilitation treatment such as MIRT could improve QoL in patients with PD in the short-term and long-term period. Even though the single-blind design and the possible role of the placebo effect on the conclusive results must be considered as limitations of this study, the improvement in outcome measure, also maintained after a 3-month follow-up period, suggests the effectiveness of MIRT on the QoL.

Abstract
We report the first rapid ultra-high performance liquid chromatographic (UHPLC) enantiomeric reversed-phase separation of rasagiline mesylate and its tartrate salts using a Chiralpak® AGP column (50 mm × 2.1 mm, 5 μm) as a stationary phase. This method was developed as an alternative to the usage of previously reported normal-phase chiral LC columns for isomer separation. Our method is based on an isocratic approach using a mixture of ammonium acetate and isopropyl alcohol (90:10, v/v) as the mobile phase (0.6 mL/min flow rate). The detection limit (at a detection wavelength of 210 nm) and quantification limit for the rasagiline enantiomers were 0.06 and 0.2 μg/mL, respectively. This method is compatible with the UHPLC-MS technique. The successful separation of rasagiline and its enantiomer was confirmed by determining the corresponding specific optical rotation values. Our method will be applicable for detecting rasagiline enantiomers during the control of manufacturing processes, and for use in rapid analysis for quality control in pharmaceutical industry to obtain optically pure pharmaceutical substances. This method was validated in terms of its precision, limit of detection, limit of quantification, linearity, accuracy, robustness, ruggedness, specificity, forced degradation, and solution stability, according to International Council on Harmonization Validation Guidelines Q2 (R1).

Abstract
Current options for Alzheimer's disease (AD) treatment are based on administration of cholinesterase inhibitors (donepezil, rivastigmine, galantamine) and/or memantine, acting as an N-methyl-D-aspartate (NMDA). Therapeutic approaches vary and include novel cholinesterase inhibitors, modulators of NMDA receptors, monoamine oxidase (MAO) inhibitors, immunotherapeutics, modulators of mitochondrial permeability transition pores (mPTP), amyloid-beta binding alcohol dehydrogenase (ABAD) modulators, antioxidant agents, etc. The novel trends of AD therapy are focused on multiple targeted ligands, where mostly ChE inhibition is combined with additional biological properties, positively affecting neuronal energy metabolism as well as mitochondrial functions, and possessing antioxidant properties. The present review summarizes newly developed drugs targeting cholinesterase and MAO, as well as drugs affecting mitochondrial functions.

Abstract
BACKGROUND Although numerous prescription drugs are available to treat Parkinson's disease (PD), little is known about national use in clinical practice and which factors may influence variability in care. The objectives of this study were to describe the prevalence of anti-Parkinson drug use among Medicare beneficiaries with PD and to identify demographic and clinical factors associated with drug use. METHODS This retrospective study was based on a random sample of annual 5% Medicare Part A and B claims linked with Medicare Part D drug files from 2007 through 2010. The study sample included fee-for-service Medicare beneficiaries with continuous stand-alone Part D enrollment who had been diagnosed with PD in the given year. First, any PD drug use and drug use by class (levodopa, dopamine agonist, anticholinerigc, monoamine oxidase B inhibitors, catechol-O-methyltransferase inhibitors, and amantadine) were described. Using generalized estimating equation regressions, patient and provider characteristics associated with anti-Parkinson drug use and choice were examined. RESULTS Over 81% of patients with PD were treated with anti-Parkinson drugs, and this proportion was stable over the 4 years of the study. The majority were treated with levodopa (90%); followed by dopamine agonists (29-31%); then monoamine oxidase B inhibitors, anticholinergics, amantadine, and catechol-O-methyltransferase inhibitors (all between 5% and 11%). Holding all else equal, patients who were not seen by a neurologist (odds ratio, 0.41; 95% confidence interval, 0.38-0.44; P < 0.001) and African-American patients (odds ratio, 0.80; 95% confidence interval, 0.69-0.93; P = 0.003) were significantly less likely to be treated. CONCLUSIONS Among a national sample of Medicare beneficiaries with PD, the majority received anti-Parkinson drugs. However, there was relative under-treatment of African-Americans and patients who were not seen by a neurologist for care.

Abstract
Health-related quality of life is a patient-reported outcome that complements clinical evaluation and provides information about disease activity and effects of the treatment. The objective of this review is to present the conceptual framework, the measures, and some of their most relevant applications in the field of Parkinson's disease and movement disorders. Health-related quality of life is a subjective, individual, and multidimensional construct, and its main dimensions are physical, mental, and social, besides global perceptions of health and personal domains. Health-related quality of life measurement is carried out by means of questionnaires or scales, ideally self-applied by patients, and has a diversity of important applications for clinical practice, research, and health policy. Movement disorders and Parkinson's disease are complex conditions impacting all components of patients' health-related quality of life. The use of health-related quality of life tools provides important information on a variety of aspects that are important to patients while complementing clinical evaluations. In particular, studies using this kind of assessment can identify and monitor the most important health-related quality of life determinant factors, allowing tailored assistance and prioritized interventions. In addition, maintaining or improving the patients' health-related quality of life is an objective of care for chronic diseases and, therefore, it has to be monitored over time and as an outcome of clinical trials. Several methods are available for the interpretation of the change in scores of health-related quality of life measures, although a definitive agreement on the most appropriate method is yet to be determined. Presently, health-related quality of life assessment is an important outcome for research and management of chronic conditions such as Parkinson's disease and other movement disorders. © 2016 International Parkinson and Movement Disorder Society.

Jakova E, Lee JS. Behavior of α-synuclein-drug complexes during nanopore analysis with a superimposed AC field. Electrophoresis 2016; 38:350-360.

Abstract
Seven α-synuclein-drug complexes have been studied by nanopore analysis in which an AC field of 200 mV from 10 MHz to 1 GHz has been superimposed on the standard electrophoretic DC voltage of 100 mV. α-Synuclein has a large dipole moment and in the absence of drug the AC field causes the molecule to oscillate at the entrance to the pore and reduces its ability to translocate through the pore. Thus more bumping events are observed in the current blockade histograms. The binding of drugs to α-synuclein has a large effect on the event profiles depending on the region of α-synuclein to which the drugs bind. Caffeine and (-)-nicotine bind both the N- and C-termini causing the protein to adopt a loop conformation that allows translocation even in the AC field. Metformin, which binds only to the C-terminus also facilitates translocation. For these drugs there is good evidence that the AC field is causing the complex to dissociate as it enters the pore that has not been observed previously. In contrast, complexes with (+)-amphetamine that has an N-terminal binding site and cocaine that binds to the central region of the protein, show only small changes in the event profiles in an AC field.

Abstract
Progress in understanding the role of monoamine neurotransmission in pathophysiology of neuropsychiatric disorders was made after the discovery of the mechanisms of action of psychoactive drugs, including monoamine oxidase (MAO) inhibitors. The increase in monoamine neurotransmitter availability, decrease in hydrogen peroxide production, and neuroprotective effects evoked by MAO inhibitors represent an important approach in the development of new drugs for the treatment of mental disorders and neurodegenerative diseases. New drugs are synthesized by acting as multitarget-directed ligands, with MAO, acetylcholinesterase, and iron chelation as targets. Basic information is summarized in this paper about the drug-induced regulation of monoaminergic systems in the brain, with a focus on MAO inhibition. Desirable effects of MAO inhibition include increased availability of monoamine neurotransmitters, decreased oxidative stress, decreased formation of neurotoxins, induction of pro-survival genes and antiapoptotic factors, and improved mitochondrial functions.

Abstract
Background and Purpose Nonmotor symptoms (NMS) in Parkinson's disease (PD) have multisystem origins with heterogeneous manifestations that develop throughout the course of PD. NMS are increasingly recognized as having a significant impact on the health-related quality of life (HrQoL). We aimed to determine the NMS presentation according to PD status, and the associations of NMS with other clinical variables and the HrQoL of Korean PD patients. Methods We surveyed patients in 37 movement-disorders clinics throughout Korea. In total, 323 PD patients were recruited for assessment of disease severity and duration, NMS, HrQoL, and other clinical variables including demographics, cognition, sleep scale, fatigability, and symptoms. Results In total, 98.1% of enrolled PD subjects suffered from various kinds of NMS. The prevalence of NMS and scores in each NMS domain were significantly higher in the PD group, and the NMS worsened as the disease progressed. Among clinical variables, disease duration and depressive mood showed significant correlations with all NMS domains (p<0.001). NMS status impacted HrQoL in PD (rS=0.329, p<0.01), and the association patterns differed with the disease stage. Conclusions The results of our survey suggest that NMS in PD are not simply isolated symptoms of degenerative disease, but rather exert significant influences throughout the disease course. A novel clinical approach focused on NMS to develop tailored management strategies is warranted to improve the HrQoL in PD patients.

Abstract
Quality of life (QoL) is a patient-reported outcome frequently included in Parkinson's disease (PD) clinical trials as a secondary or tertiary endpoint. However, QoL is an important variable that reflects the impact of disease and treatment from the patients' perspective. In a chronic, neurodegenerative disease such as PD, with a wide range of complex symptoms, QoL provides valuable and comprehensive information on the patients' health status. This narrative review aims to evaluate the effect of specific PD treatments currently in use on patients' QoL measured with the Parkinson's Disease Questionnaire, 39-item (PDQ-39) or 8-item (PDQ-8) version. A quantification of this effect is provided by calculation of the relative change and effect size. These two parameters allow an intuitive standardized approach to the importance of change based on its magnitude. Some high-quality studies (Level I) were found for levodopa (immediate- or extended-release formulations), levodopa with added-on catechol-O-methyltransferase (COMT) inhibitors, levodopa/carbidopa gel for intestinal infusion, some dopamine agonists (ropinirole, cabergoline, pergolide), and the monoamine oxidase B (MAO-B) inhibitor safinamide. As a whole, these studies found a beneficial effect of variable magnitude, weak to moderate, on patients' QoL. Studies with a lower level of evidence or not providing enough data to estimate relative change and effect size, including those for the apomorphine subcutaneous pump, also reported improvement of QoL, but the evidence was insufficient to confirm the effect. More high-quality studies focused on QoL are needed to determine the real impact of PD drug treatments for this important outcome.

Abstract
The aim of the present study was to prepare and evaluate a rasagiline-loaded chitosan glutamate nanoparticles (RAS-CG-NPs) by ionic gelation of CG with tripolyphosphate anions (TPP). RAS-loaded CG-NPs were characterized for particle size, size distribution, encapsulation efficiency and in vitro drug release. The mean particles size, polydispersity index (PDI) and encapsulation efficiency was found to be 151.1 ± 10.31, 0.380 ± 0.01 and 96.43 ± 4.23, respectively. Biodistribution of RAS formulations in the brain and blood of mice following intranasal (i.n.) and intravenous (i.v.) administration was performed using HPLC analytical method. The drug concentrations in brain following the i.n. of CG-NPs were found to be significantly higher at all the time points compared to both drug (i.n.) and drug CG-NPs (i.v.). The Cmax (999.25 ng/ml) and AUC (2086.60 ng h/ml) of formulation CG-NPs (i.n) were found to be significantly higher than CG-NPs (i.v.) and RAS solution (i.n.). The direct transport percentage (DTP%) values of RAS-loaded CG-NPs (i.n.) as compared to drug solution (i.n.) increased from 66.27 ± 1.8 to 69.27 ± 2.1%. The results showed significant enhancement of bioavailability in brain, after administration of the RAS-loaded CG-NPs which could be a substantial achievement of direct nose to brain targeting in Parkinson's disease therapy.

Abstract
Neuropsychiatric and cognitive symptoms are common in patients with Parkinson's disease (PD) from the early stage of the disease but their course is still unclear. In this study we investigated prospectively the progression of affective and cognitive symptoms and disorders in de novo idiopathic PD patients. Twenty-four de novo drug naïve PD patients underwent a comprehensive neurological, psychopathological and neuropsychological evaluation at the first diagnostic visit (OFF), after 4-6 months when the antiparkinsonian therapy regimen was stabilized (ON-1), and at one year following the ON-1 follow-up visit (ON-2). Generalized least squares analysis revealed a significant improvement over time in the depressive mood, short and long term episodic verbal memory, visual memory, and the motor symptoms. Pairwise comparisons showed a significant change from OFF to ON-1 for all the aforementioned variables, except for short term episodic verbal memory which approached significance. A significant improvement from ON-1 to ON-2, however, was shown for short term episodic verbal memory. An ancillary analysis indicated that overall level and change in a number of cognitive variables, but not depression, was conditional upon age of onset, education, and sometime gender. In conclusion, early stage PD is not associated with affective and cognitive deterioration. On the contrary, very specific neuropsychiatric and cognitive symptoms may improve. This study provides Class III evidence that antiparkinsonian treatment commonly used in the clinical practice improves memory performance and depression severity in de novo patients with PD.

Abstract
Background The purpose of this study was to draw conclusions from patient-reported experiences in two national surveys from Scandinavia with the intention of comparing treatment strategies and increasing our knowledge of factors that affect the experiences of patients with Parkinson’s disease (PD). Methods A total of 2000 individuals in Sweden and 1300 in Norway were invited to complete postal surveys covering PD-related issues. Patient experiences of diagnostic procedures, symptom control, and follow-up in PD and the effects on symptom-related quality of life were collected. Pharmaceutical prescription data on anti-PD drugs and administrative data were collected from national registries. Results The surveys were completed by 1553 (78%) of the Swedish cohort and 1244 (96%) of the Norwegian cohort. Only small differences were seen in disease duration and age distribution. Statistically as well as clinically significant differences in symptom control, diagnostic, and follow-up procedures, as well as in pharmacological treatment and impact on quality of life, were found between the national cohorts independent of disease duration. Conclusion Information from separate national surveys has the potential to increase our knowledge of patient experiences in PD and can be used to compare, evaluate, educate, and guide health care staff and administrators in optimizing health care for patients with the disease.

Abstract
The prevalence of non-motor symptoms in Parkinson's disease (PD) is high. Depression varies from 20 to 50% of the PD patients, and is associated with increasing disability. The key characteristics of depression are anhedonia and low mood. The recommended scales for screening purposes are: HAM-D, BDI, HADS, MADRS and GDS. As for measurement of severity: HAM-D, MADRS, BDI and SDS. In cases with mild depression, non-pharmacological intervention is the treatment of choice. In moderate depression, antidepressants are required. The choice of an antidepressant should be based mainly on the comorbidities and unique features of the patient. Evidence for antidepressant effectiveness is seen mostly with amitriptyline and nortriptyline, but one should be cautious in elderly patients. Other antidepressants that can be prescribed are: citalopram, escitalopram, sertraline, bupropion, trazodone, venlafaxine, mirtazapine and duloxetin. The dopaminergic agonist pramipexole is a treatment option.

Abstract
The comparative safety profiles of monotherapeutic treatments for Parkinson's disease (PD) can provide valuable therapeutic information. The objective of this study was to perform an indirect comparison of Adverse Events (AEs) and Dropout Rates (DRs) among clinical trials of pramipexole, ropinirole, and rasagiline. Outcomes analyzed included DRs, total AEs, and AE categories: Cognitive (CG), Gastrointestinal (GI), and Sleep/Fatigue (SF). The odds-ratio (OR) and Credible Interval (CrI) of outcomes between products using placebo as common comparator was calculated using indirect meta-analytical methods. AEs incidences for subjects receiving rasagiline were not significantly different from placebo, whereas DRs were significantly lower than for placebo (OR = 0.55; 95% CrI = 0.34-0.88). Patients receiving pramipexole or ropinirole had higher incidence of all AEs and DRs than patients taking rasagiline, except for the nonsignificant incidence of CG for ropinirole vs. rasagiline (1.76; 0.69-4.70). The incidence of GI (2.11; 1.13-4.06) and SF (2.75; 1.42-5.47) was significantly higher for ropinirole than for pramipexole, whereas the incidence of CG was significantly lower for ropinirole than for pramipexole (0.22; 0.07-0.69). Findings suggest that subjects with early PD treated with rasagiline have fewer AEs and DRs than those treated with pramipexole or ropinirole. GI and SF AEs were highest for subjects treated with ropinirole, while individuals treated with pramipexole exhibited the highest incidence of cognitive AEs.

Abstract
In the past three decades, health-related quality of life (HRQoL) has become an outcome variable in Parkinson's disease clinical trials. This review considers the measuring tools that have been developed, suitability of data reporting, complexity of outcome interpretation, and clinical application to provide evidence regarding available therapeutic interventions to date. In the introduction, different terms regarding quality of life are clearly defined. The methodology section offers an overview of generic, disease specific, and recommended HRQoL scales in Parkinson's disease and the most important psychometric attributes a scale should meet. The interpretation of HRQoL outcomes is complex and not intuitive. Thus, appropriate reporting of data is crucial in order to calculate relative change, a result that facilitates understanding to what extent an intervention is beneficial. The concept of minimally important change/difference is explained as well as the different approaches to its calculation (anchor-based and distribution-based methods). In the results section, a brief overview of the impact on HRQoL of currently available treatments in Parkinson's disease is provided. Special emphasis is given to data assessment, highlighting reports that helped understanding of the clinical significance of the intervention and therefore aided in making therapeutic decisions. The discussion section emphasizes the need for more clinical trials with HRQoL as a primary outcome and standardized reporting in order to further our understanding of the complexity of treatment effects and make evidence-based clinical decisions regarding HRQoL in patients with Parkinson's disease.

Abstract
Psychiatric symptoms are important non-motor features in PD, which occur at high frequency and have significant impact on health related quality of life. This review concentrates on the prevalence, pathophysiology, diagnosis and treatment of depression, anxiety, apathy and psychosis. The pathophysiology of these disorders is complex, reflecting the widespread brainstem and cortical pathology in PD, with involvement of several neurotransmitters, including dopaminergic, serotonergic, noradrenergic and cholinergic systems. The diagnosis of psychiatric conditions, in particular affective disorders, is challenging because of the overlap of somatic features of psychiatric disorders and underlying movement disorder. The pathogenesis is likely to differ considerably from non-PD patients, and treatments used in general psychiatry services may not be as effective in PD and will require clearer clarification in well-designed clinical studies. Management strategies include adjustment of dopaminergic medication, use of psychotropic treatments and behavioural and psychological approaches. However, the future challenge will be to develop treatments developed specifically for the pathogenesis of these disorders in PD.

Abstract
BACKGROUND Parkinson's disease (PD) patients' own knowledge and experience and access to information, in relation to advanced treatment methods, are very limited. The aim of this study was to map out PD patients' perception about various advanced treatment methods, their availability and regional differences in medical care, and to investigate patients' experience of their medication and quality of life. METHODS A survey was sent to 4886 PD patients of the Swedish Parkinson's Disease Association covering demography, the patient's illness, current treatment, received information about advanced treatment alternatives, and health status. Advanced PD was considered as patients diagnosed >5 years ago, using PD medication >5 times/day, and experiencing motor complications >2 hours/day. RESULTS In total, 3327/4886 persons (68%) responded (57% men) of which 1300 (39%) were classified as having advanced PD. Mean age was 71 years with a median disease duration of 8 years. The treating physician was a neurologist (86%) but varied between counties (96% to 52%) and was most frequent in urban areas. Doctor appointments were 1.7 times/year with regional variation (2.1 to 1.1). Three out of four patients had heard of advanced treatment options and were interested, but were denied treatment. Only a small proportion of patients were informed of these by their physician. Nine percent were satisfied with their medication (including 4% of advanced patients). One third of patients experienced their general health as poor or very poor. CONCLUSION The majority of Swedish PD patients are treated by neurologists. Annual numbers of doctors' appointments were low in an international context and can partly be explained by the shortage of neurologists and other trained specialists. Doctors only provided a small proportion of patients with advanced therapy information, despite patients' interest. Hence, improvement is warranted regarding doctor appointments, information about various advanced treatment options, and their availability.

Abstract
BACKGROUND Data regarding both drug-related and non-drug-related costs in patients with Parkinson's disease (PD) are scarce, mainly due to the difficulties in data acquisition in experimental designs. Likewise, the reported impact of drug costs on total direct costs varies across different studies. In addition, the influence of comorbidities on both treatment costs and health-related quality of life has not been adequately evaluated. METHODS A sample of office-based neurologists (n=315) in Germany was asked to examine up to five consecutive patients with PD (n=1449) on a specified day during the study period. Patients of all ages were eligible and their evaluation was performed using standardized questionnaires. RESULTS PD-specific therapy costs increased with the stage of the disease, early onset of the disease and disease duration. The major costs were due to PD-related therapy, whereas other medications only resulted in minor costs. Disease stage mainly influenced direct therapy costs, with an observed increase of total daily costs from €7.3 to €11.3/day. In addition, disease onset at age <65 years resulted in total daily costs of €11.2 compared to late onset of disease (>75 years) with daily therapy costs of €5.3. In this patient group neuropsychiatric comorbidities such as dementia and depression were only insufficiently treated. In addition, these comorbidities severely affected health-related quality of life. CONCLUSION Therapy costs were influenced by disease stage, disease onset as well as present comorbidities. Furthermore, comorbidities such as depression and dementia were diagnosed but were not adequately treated.

Abstract
Background To identify key non-motor symptoms of Parkinson's disease (PD) to include in a daily diary assessment for off-time, revise the Scales for Outcomes of Parkinson's disease Diary Card (SCOPA-DC) to include these non-motor symptoms, and investigate the validity, reliability and predictive utility of the Revised SCOPA-DC in a U.S. population. Methods A convenience sample was used to recruit four focus groups of PD patients. Based on findings from focus groups, the SCOPA-DC was revised and administered to a sample of 101 PD patients. Confirmatory factor analysis was conducted to test the domain structure of the Revised SCOPA-DC. The reliability, convergent and discriminant validity, and ability to predict off-time of the Revised SCOPA-DC were then assessed. Results Based on input from PD patients, the Revised SCOPA-DC included several format changes and the addition of non-motor symptoms. The Revised SCOPA-DC was best represented by a three-factor structure: Mobility, Physical Functioning and Psychological Functioning. Correlations between the Revised SCOPA-DC and other Health-Related Quality of Life scores were supportive of convergent validity. Known-groups validity analyses indicated that scores on the Revised SCOPA-DC were lower among patients who reported experiencing off-time when compared to those without off-time. The three subscales had satisfactory predictive utility, correctly predicting off-time slightly over two-thirds of the time. Conclusions These findings provide evidence of content validity of the Revised SCOPA-DC and suggest that a three-factor structure is an appropriate model that provides reliable and valid scores to assess symptom severity among PD patients with symptom fluctuations in the U.S.

Abstract
OBJECTIVE To analyze the change in health-related quality-of-life (HRQoL) in patients with Parkinson's disease (PD) and to identify different classes of HRQoL decline. METHODS A longitudinal cohort study was performed to assess clinical parameters (unified PD rating scale, Beck Depression Inventory) and HRQoL data (EuroQol, Parkinson's Disease Questionnaire [PDQ]-39) at baseline, 3, 6, 12, 24, and 36 months. A total of 145 patients with PD were consecutively recruited in the county of Northern Hessia, Germany, between January and June 2000. A latent growth mixture model was applied to analyse the heterogeneity in HRQoL trajectories. RESULTS We successfully applied latent mixture growth modeling in order to identify different classes of HRQoL trajectories in PD. Three growth models were developed and each resulted in a four-class model of distinct patterns using the generic EuroQol instruments' outcomes (EuroQol-5 Dimensions and visual analogue scale) and the disease-specific PDQ-39. The four classes were defined by individual trajectory characteristics. Classes one and two represented trajectories with moderate declines over 36 months, but with different initial intercepts. Class three consisted mainly of patients who passed away during the observation period and therefore had a large HRQoL decline. Class four was characterized by a low level of HRQoL at baseline and a significant subsequent decline. CONCLUSIONS The findings provide a more elaborate understanding of the variability in HRQoL reduction in PD over time. The classification of different HRQoL subgroups may help to explain the response of PD patients to the natural history of the disease. Future research will enable the identification of HRQoL responder subgroups on different treatment regimens.

Abstract
Dopamine receptor agonists are indicated for the symptomatic treatment of early, moderate or advanced Parkinson's disease as well as for the reduction of levodopa-related motor complications. Ergolinic dopamine agonists, such as bromocriptine or pergolide, were initially developed and marketed, and then non-ergolinic dopamine agonists, such as pramipexole and ropinirole, were introduced, reducing the risk of drug-induced fibrotic reactions. Once-daily, controlled-release oral and transdermal formulations have been developed aiming at providing more stable 24-hour plasma drug concentrations and more convenient administration. A disease-modifying effect of dopamine agonists has not been demonstrated clinically. As with any other drug, dopamine agonists can also cause adverse drug reactions, which can be related or unrelated to dopaminergic hyperactivation. Dopaminergic reactions include nausea, hallucinations, confusion and orthostatic hypotension, among others, which were readily identified in pre-marketing clinical trials. During post-marketing surveillance, important adverse reactions were identified, such as daytime somnolence, impulse-control disorders and heart valve fibrosis. Other issues, including the efficacy of dopamine agonists for the treatment of non-motor symptoms, remain under evaluation.

Abstract
Though L-3,4-dihydroxyphenylalanine (L-DOPA) is universally employed for alleviation of motor dysfunction in Parkinson's disease (PD), it is poorly-effective against co-morbid symptoms like cognitive impairment and depression. Further, it elicits dyskinesia, its pharmacokinetics are highly variable, and efficacy wanes upon long-term administration. Accordingly, "dopaminergic agonists" are increasingly employed both as adjuncts to L-DOPA and as monotherapy. While all recognize dopamine D(2) receptors, they display contrasting patterns of interaction with other classes of monoaminergic receptor. For example, pramipexole and ropinirole are high efficacy agonists at D(2) and D(3) receptors, while pergolide recognizes D(1), D(2) and D(3) receptors and a broad suite of serotonergic receptors. Interestingly, several antiparkinson drugs display modest efficacy at D(2) receptors. Of these, piribedil displays the unique cellular signature of: 1), signal-specific partial agonist actions at dopamine D(2)and D(3) receptors; 2), antagonist properties at α(2)-adrenoceptors and 3), minimal interaction with serotonergic receptors. Dopamine-deprived striatal D(2) receptors are supersensitive in PD, so partial agonism is sufficient for relief of motor dysfunction while limiting undesirable effects due to "over-dosage" of "normosensitive" D(2) receptors elsewhere. Further, α(2)-adrenoceptor antagonism reinforces adrenergic, dopaminergic and cholinergic transmission to favourably influence motor function, cognition, mood and the integrity of dopaminergic neurones. In reviewing the above issues, the present paper focuses on the distinctive cellular, preclinical and therapeutic profile of piribedil, comparisons to pramipexole, ropinirole and pergolide, and the core triad of symptoms that characterises PD-motor dysfunction, depressed mood and cognitive impairment. The article concludes by highlighting perspectives for clarifying the mechanisms of action of piribedil and other antiparkinson agents, and for optimizing their clinical exploitation.

Abstract
Here we report structure-activity relationship study of a novel hybrid series of compounds where structural alteration of aromatic hydrophobic moieties connected to the piperazine ring and bioisosteric replacement of the aromatic tetralin moieties were carried out. Binding assays were carried out with HEK-293 cells expressing either D2 or D3 receptors with tritiated spiperone to evaluate inhibition constants (K(i)). Functional activity of selected compounds in stimulating GTPgammaS binding was assessed with CHO cells expressing human D2 receptors and AtT-20 cells expressing human D3 receptors. SAR results identified compound (-)-24c (D-301) as one of the lead molecules with preferential agonist activity for D3 receptor (EC(50) (GTP gamma S); D3 = 0.52 nM; D2/D3 (EC(50)): 223). Compounds (-)-24b and (-)-24c exhibited potent radical scavenging activity. The two lead compounds, (-)-24b and (-)-24c, exhibited high in vivo activity in two Parkinson's disease (PD) animal models, reserpinized rat model and 6-OHDA induced unilaterally lesioned rat model. Future studies will explore potential use of these compounds in the neuroprotective therapy for PD.
