Abstract
Background Sexual health (SH) is influenced by several biological, mental, and social factors that may be negatively impacted by Parkinson's disease (PD). Despite its prevalence and relevance for quality of life, the factors that affect SH in men with PD (MwPD) are still poorly understood. Objectives To investigate the impact of motor, non-motor, and social aspects on the SH in MwPD. Methods We conducted a cross-sectional study of 80 men (mean-age 53.55±10.8) in stages 1-3 of Hoehn and Yahr classification (H&Y), who reported having an active sex life in the last six months. The following data were collected for each person: 1) Demographic and clinical features; 2) global cognitive capacity (T-MoCA); 3) Non-Motor Aspects of Experiences of Daily Living (MDS-UPDRS, part I); 4) Motor Aspects of Experiences of Daily Living (MDS-UPDRS, part II); 5) Fatigue (FSS); 6) Self-esteem (RSES); 7) Sleep disorder (PDSS); 8) Couple relationship quality (DAS); 9) Depressive signals (BDI); 10) Short-term sexual health by International Index of Erectile Function (IIFE); and 11) Long-term sexual health by Sexual Quotient-Male (SQ-M). Results Our results showed that although several motor, non-motor, and social factors were correlated with SH, only motor disability levels in daily living predicted short-term SH and erectile dysfunction, while only depression predicted long-term SH in MwPD. Age, disease onset, and medication daily dosage were not correlated with SH. Conclusions Our findings confirm that multidimensional factors can affect the SH of MwPD and emphasize that only a multi-professional team can offer proper care to improve SH in MwPD.

Abstract
Background People with Parkinson's disease (PwPD) exhibit various sexual difficulties (SDs) that may be due to motor and/or nonmotor symptoms or the use of antiparkinsonian medication. SDs are often underreported by PwPD and underexplored by physicians. Objective This study aimed to explore the SDs experienced by PwPD and create a scale for assessing them. Methods A corpus of items was generated from semistructured interviews to represent the experience of PwPD as closely as possible. The number of items was reduced according to the psychometric properties, and the scale's structure was subsequently examined. The final phase consisted of measuring the scale's validity and reliability. Results After assessment of the original corpus of 59 items by PwPD and clinicians, a 25-item version was obtained. The analysis of item properties led to the removal of fifteen items. An exploratory factor analysis of the first 10-item version with a first PwPD sample identified four components of the SDs among PwPD: "low sexual esteem," "sexual displeasure," "impact on sexual position" and "hypersexuality." With a second PwPD sample, a confirmatory factor analysis demonstrated a satisfactory fit between the model with four components and the data. The 10-item scale had good internal consistency and good temporal reliability. Conclusions The Parkinson's Disease Sexual Difficulties Scale (PD-SDS) is a valid screening tool that facilitates the investigation of and communication about PD-related SDs. It is intended to improve the identification of vulnerable PwPD and to target the domain of sexual experience impacted by PD to better support PwPD.

Sexual Dysfunctions in Females with Parkinson's Disease: A Cross-Sectional Study with a Psycho-Endocrinological Perspective. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59050845.

Abstract
Background and Objectives: Normal human sexual functioning is a complex integration of an intact neuroanatomic substrate, vascular supply, a balanced hormonal profile, and a predominance of excitatory over inhibitory psychological mechanisms. However, sexual functioning in Parkinson's disease (PD) is often overlooked in clinical practice, especially in female patients. Materials and Methods: In this cross-sectional study, we have investigated the frequency of sexual dysfunction and the possible correlation with psycho-endocrinological factors in a sample of women with idiopathic PD. Patients were assessed using a semi-structured sexual interview, in addition to psychometric tools, including the Hamilton Rating Scale for Anxiety and for Depression and the Coping Orientation to the Problems Experiences-New Italian Version. Specific blood tests, including testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen E2, prolactin (PRL), and vitamin D3 were also evaluated. Results: Our results reported a statistical difference in sexual intercourse frequency before and after the onset of PD (p < 0.001). The percentage of women who complained about reduced sexual desire increased after diagnosis (52.7%) compared to the period before the onset of the illness (36.8%). The endocrinological profile in females with PD revealed statistically significant differences regarding testosterone (p < 0.0006), estradiol (p < 0.00), vitamin D3 (p < 0.006), and calcium (0.002). Depression (44% characterized by perceived feelings of anger and frustration during sexual intercourse) and anxiety symptoms (29.5% reported feelings of fear and anxiety for not satisfying the partner) with abnormal coping strategies (48.14% experienced feelings of anger and intolerance) were also found to be statistically significant. This study showed a high frequency of sexual dysfunction in female patients with PD, which correlated with sexual hormone abnormalities, mood/anxiety, and coping strategies alterations. This supports the idea that there is a need to better investigate the sexual function of female patients with PD to provide them with an adequate therapeutic approach and potentially improve quality of life.

Abstract
BACKGROUND Sexual dysfunction (SD) is a frequent non-motor symptom in Parkinson's disease (PD) that is rarely addressed, and sexual counseling is sporadic. OBJECTIVES To investigate PD patients' SD and sexual counseling motivation and to propose an interventional strategy for movement disorder specialists. METHODS All consecutive PD patients who presented to a movement disorder unit between 2018 and 2019 completed anonymous questionnaires containing the Female Sexual Function Index, the International Index of Erectile Function, and a questionnaire on sexual needs and motivation to receive sexual counseling. RESULTS The age range of the 100 recruited patients (78 men) was 40-80 years, and the mean disease duration was 8.64 ± 6.84 years. SD appeared at all PD stages. The presence of SD pre-PD diagnosis significantly predicted SD post-diagnosis in men. Erectile dysfunction was the most common male SD (70%). Women reported frequent SD before PD diagnosis and currently. More than half of the responders (74% of the men and 40% of the women) were motivated to receive sexual counseling. Most of them (77.4%) were in a relationship. CONCLUSIONS The findings of this analysis revealed that most PD patients had experienced SD before being diagnosed with PD and were interested in receiving sexual counseling. We propose a six-step intervention strategy for the management of SD in PD designed for application in a movement disorder unit. We also recommend that neurologists and other healthcare providers undergo training to provide basic sexual counseling tailored to the needs of PD patients.

The association between Parkinson's disease and Sexual dysfunction: Clinical correlation and therapeutic implications. Ageing Res Rev 2022; 79:101665.

Abstract
Sexual function which comprises of desire, arousal, orgasm and satisfaction and pain, involves coordinated physiologic responses from multiple different pathways. Sexual dysfunction (SD) occurs when these domains of the sexual response cycle are affected. SD is a common but under-recognized non-motor feature in Parkinson's disease (PD), a common age-related neurodegenerative disorder. SD significantly affects the quality of life of PD patients and their partners. Advanced age, gender, hormone deficiency, neuropsychiatric and medical comorbidities contribute to SD in PD. Possible potential pathological mechanisms include vasculogenic, endocrinologic, neurogenic and psychogenic factors. Various therapeutic interventions, both pharmacological and non-pharmacological modalities have been suggested to improve SD in PD. However, erectile dysfunction (ED) is the only SD with evidence-based treatment available. Non-pharmacological therapies are also offering promising evidence in the improvement of SD. A multidisciplinary approach in the assessment, investigation, and treatment is needed to address the real life complex issues (gender and comorbidities, neurobiological, vasoactive, hormonal as well as psychosocial aspects). Future clinical studies with validated and standardized methods in assessing SD as well as experimental models will be necessary for better insight into the pathophysiology. This would facilitate appropriate therapy and improve sexual rehabilitation in PD patients.

Abstract
Nonmotor symptoms of Parkinson's disease (PD) range from neuropsychiatric and cognitive to sleep, sensory, and genito-urinary disorders, and occur as a result of the disease process as well as due to side effects of drug treatment for PD. Sexual dysfunction is an important aspect of the nonmotor profile of Parkinson's but is rarely discussed. Sexual health is considered an integral element of holistic health, thus sexual dysfunction can also significantly impact quality of life in people with Parkinson's. The effect of sexual dysfunction of PD, both disease related and drug induced, on the concept of "wellness" of patients and their intimate partners is poorly understood, inadequately researched and a key unmet need in care and support. In this chapter we discuss the concept of "wellness" as applied to the treatment of PD, the ways in which nonmotor symptoms and other aspects of living may affect wellness in PD, and strategies for addressing sexual health utilizing a wellness model.

Abstract
Sexual dysfunction is one of the commonest non-motor symptoms in Parkinson's disease (PD) and has been found about twice as high in PD patients compared to age-matched controls. The quality of sexual life is reduced in PD patients compared to healthy peers and impairment affects wide aspects of physical sexual function as well as sexual desire, sexual satisfaction and sexual partnership. Overall, male PD patients are more frequently affected by sexual disorders than females and seem to suffer more from sexual impairment. The reported frequencies and presentations of various sexual dysfunctions vary widely in the literature, which is likely related to the patient cohorts examined, in particular with regard to age and gender, duration and severity of disease and applied measurement instruments. This chapter gives an overview of the prevalence, phenotype and clinical presentation of sexual dysfunction in PD and its influence on the partnership.

Abstract
Hypersexuality (HS), characterized by an aberrant, compulsive and inappropriate sexual drive, is an underreported and undermanaged complication of the treatment with dopamine agonists in patients with Parkinson's disease (PD). HS is part of the spectrum of impulse control disorders (ICDs). The failure to control these addictive behaviors is distressing for the patient and it is associated with important consequences. Reports of the prevalence of HS showed different results, due to the lack of standardized diagnostic criteria, but also due to the embarrassment or guilt feelings that patients experience regarding their sexual behaviors. Overall, it is considered that HS may occur in 1.92-22.8% of PD patients and the main risk factors involved could be male sex and genetic susceptibility. The pathophysiology of HS is unknown, but several degenerative mechanisms were proposed, involving dopaminergic, serotoninergic and noradrenergic pathways in cerebral regions responsive for planning and rewarding. There are no standardized tools for the assessment of HS in PD patients; however, several scales and questionnaires were developed with the aim of screening and rating the severity of ICDs, including HS. The management of HS is challenging. Discontinuation or reducing the dopaminergic treatment was effective in some cases, but it might lead to worsening of the motor function. A multidisciplinary approach is mandatory to manage the other associated aspects, such as psychological and social consequences of HS.

Abstract
Sexual dysfunction is a very frequent non-motor symptom in Parkinson's disease (PD). However, patients are often reluctant to declare their sexual problems and many clinicians do not inquire about them during routine visits. The use of validated rating scales and questionnaires allows overcoming these difficulties, characterizing the nature and causes of the patient's sexual dysfunction, and helping to implement and monitor the most adequate interventions. There is a wide range of instruments available for assessing sexual dysfunction in PD, including generic and specific ones. In this chapter, we review the most used rating scales and questionnaires, with a description of its components, characteristics and psychometric attributes.

Abstract
Sexual dysfunctions (SD) are frequent and highly disabling nonmotor manifestations of Parkinson's disease (PD) but are also potentially treatable. Neurologists should actively discuss, recognize and treat sexual health issues as an integral part of the management of the disease. In this chapter, we provide recommendations for managing and treating both primary and secondary SD in PD. Many sexual problems can be, at least partially, improved by adjusting the treatment of motor, nonmotor symptoms and comorbidities. Although some treatments of primary SD are evidence-based, many therapeutic options have not been yet systematically studied in patients with PD. The development of new treatments and repurposing of existing remedies in patients with PD remain an unmet need.

Abstract
Introduction Sexual disorders are the most neglected nonmotor symptoms in Parkinson's disease (PD). Although doctors seek greater priority to motor manifestations, which are the basis for the diagnosis of PD, the nonmotor symptoms deserve to be highlighted as much as the motor problems because of their strong presence and discomfort in the patients, causing the important impairment in the quality of life (QoL) of the individual with PD. Aim Provide the prevalence of sexual disorders among patients with PD and alert the medical profession to investigate and be familiar with problems related to QoL and sexual disorders in PD. Methods This is a large literature review on sexual disorders in PD and impaired QoL. Main Outcome Measures Sexual disorders in PD and prevalence between genders have been described in epidemiological studies. Neuroanatomy, pathophysiology, risk factors, QoL, and etiologies were reviewed. Results The estimate of the prevalence of sexual dysfunction in the form of compulsive sexual behavior in PD is higher in men by 5.2% than in women by 0.5%. This diagnosis is a determinant of intense and persistent suffering and is related to several health problems of a social, economic, personal, family, psychological, and occupational nature, which can even culminate in sexual abuse. It is most commonly associated with the use of drugs commonly used in PD therapy in 98.1% of cases. In addition to this serious public health problem, another common condition of sexual dysfunction occur with the decreased libido by loss of the neurotransmitter dopamine proper of the pathophysiology of PD. Conclusion The presence of sexual disorders in PD should be tracked and monitored because of its harmful consequences, whether due to increased sexual behavior or associated psychological distress, as well as the impacts on QoL. Early recognition and adequate treatment of PD in its fullness and richness of associated symptoms are essential for improving QoL.

Abstract
Context: Lewy body (LB)-related α-synucleinopathy (LBAS) is the neuropathological hallmark of several neurodegenerative diseases such as Parkinson disease (PD), but it is also found in neurologically asymptomatic subjects. An abnormal accumulation of α-synuclein has been reported also in the spinal cord, but extent and significance of the spinal cord involvement are still poorly defined. Objective: We aimed to review the studies addressing the spinal cord involvement of LBAS in healthy subjects and in patients with PD or other neurodegenerative diseases. Methods: A MEDLINE search was performed using following terms: "spinal cord", " α-synucleinopathy", "α-synuclein", "Lewy body", "Parkinson's disease", "multiple system atrophy", "neurodegenerative disorder". Results: LBAS in the spinal cord is associated with that of the medullary reticular formation and locus ceruleus in the brainstem but not with that in the olfactory bulb and amygdala. The intermediolateral columns of the thoracic and sacral cord are the most frequently and severely affected region of the spinal cord. LBAS occurs in centrally projecting spinal cord neurons integrating pain, in particular from lower body periphery. It also involves the sacral parasympathetic nucleus innervating the smooth muscles of the bladder and distal colon and the Onuf's nucleus innervating the striated sphincters. The spinal cord lesions may thus play a crucial role in the genesis of frequent non-motor symptoms such as pain, urinary symptoms, bowel dysfunction, autonomic failure including orthostatic hypotension and sexual disturbances. Moreover, these may also contribute to the motor symptoms, since α-synuclein inclusions have been observed in the pyramidal tracts of patients with PD and multiple system atrophy. Conclusion: Recognition of this peculiar spinal cord pathology may help in the management of the related symptoms in subjects affected by α-synucleinopathies.

Nigral and ventral tegmental area lesioning induces testicular and sperm morphological abnormalities in a rotenone model of Parkinson's disease. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2020; 78:103412. [PMID: 32439558 DOI: 10.1016/j.etap.2020.103412] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 04/26/2020] [Accepted: 05/12/2020] [Indexed: 06/11/2023]
Abstract
Although sexual health is affected by Parkinson's disease (PD), the effect on testicular health and/or sperm quality is not well discussed. After 21 days of rotenone lesioning, we observed dopaminergic neuronal degeneration in the substantia nigra and hypothalamus. There were minimal SPACA-1-expressing epididymal spermatozoa with morphological abnormalities, scanty luminal spermatozoa and reduced testicular spermatids and post-meiotic germ cells indicating hypospermatogenesis. Occludin-expressing sertoli cells were dispersed over a wide area indicating compromised blood-testes barrier. Activated caspase-3 expression was intense while immunoreactivity of spermatogenic-enhancing SRY and GADD45 g was weak. Although serum follicle stimulating hormone level was not affected, the lesion was associated with reduced serum testosterone level, testicular oxidative damage and inhibition of acetylcholinesterase activity, even when rotenone was not detected in the testes. Together, dopaminergic lesions may mediate testicular and sperm abnormalities via the brain-hypothalamic-testicular circuit independent of the pituitary, thereby establishing a causal link between Parkinsonism and reproductive dysfunction.

Sexual Dysfunction in Parkinson Disease: A Multicenter Italian Cross-sectional Study on a Still Overlooked Problem. J Sex Med 2020; 17:1914-1925. [PMID: 32665210 DOI: 10.1016/j.jsxm.2020.06.010] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 04/30/2020] [Accepted: 06/10/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND Prevalence rates of sexual dysfunction (SD) in Parkinson's disease (PD) are likely to be underestimated and their etiology is still unknown. More understanding of this issue is needed. AIM To investigate prevalence of SD and its variables, including gender differences, in a sample of PD patients. METHODS This multicenter observational study included 203 patients (113 males and 90 females) affected by PD (diagnosed according to UK Parkinson's Disease Society Brain Bank clinical diagnostic criteria 28), and living in 3 different Italian regions. Patients were evaluated using a semi-structured interview (a 40-item ad hoc questionnaire, developed by the authors to investigate patient's 3 main life areas: sociodemographic information, illness perception, and sexuality) and specific standardized scales to investigate SD, as well as by means of tools to assess their motor impairment, daily life activities, and disease-related caregiver burden (CBI). MAIN OUTCOME MEASURES The International Index of Erectile Function and the Female Sexual Function Index. RESULTS Sexual dysfunction was observed in about 68% of men, and in around 53% of women loss of libido being the main sexual concern in both sexes. Men were significantly more affected by SD than women (χ2 (1) = 4.34, P-value = .037), but no difference in the severity of the dysfunction emerged between genders. Around 85% of PD patients had a stable couple relationship, and about 40% were satisfied with such a relationship. However, about 57% of the patients stated that the disease affected their sexual life, especially due to reduced sexual desire, and the frequency of sexual intercourses. Moreover, significant differences between subjects with SD and subjects without SD were found in UPDRS (I-II-III domains), in Hamilton Depression Rating Scale and CBI scores. CLINICAL IMPLICATIONS Clinicians dealing with PD should pay more attention to sexual issues, as discussing and treating sexual problems enters the framework of a holistic approach, which is mandatory in chronic illness. STRENGTHS & LIMITATIONS The major strengths of this study include the multicenter nature of the study, to overcome single-center methodological bias. The main limitation is the relatively small sample size, and the absence of a control group, even if there are growing literature data on sexuality and aging supporting our findings. CONCLUSION SD is a highly prevalent and devastating problem in patients affected by PD, negatively affecting their quality of life. Raciti L, De Cola MC, Ortelli P, et al.

Abstract
BACKGROUND Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is used in the treatment of advanced Parkinson's disease (PD) with well-established benefits over motor complications. However, few studies addressing the impact of DBS on nonmotor dimensions such as sexual function have been conducted. This study aims to determine the effect of DBS-STN on the sexual activity of patients with PD and to establish predictive factors for sexual function decline after surgery. MATERIALS AND METHODS Twenty-one patients with PD submitted to DBS-STN were compared with 19 eligible surgery candidates. Clinical measures included disease progression (Hoehn and Yahr scale), sexual function evaluation (Female Sexual Function Index and International Index of Erectile Function), severity of depressive symptoms (Beck Depressive Inventory-II), motor symptoms (Movement Disorders Society-Unified Parkinson's Disease Rating Scale Part III), and quality of life (39-item Parkinson's Disease Questionnaire). The primary outcomes were the development of sexual dysfunction in women and erectile dysfunction in men. Regression analysis was performed to outline risk factors for developing sexual function deterioration. RESULTS Erectile dysfunction was present in 83.3% of men and sexual dysfunction in 77.8% of women treated with DBS-STN. Women with sexual dysfunction had higher emotional well-being 39-item Parkinson's Disease Questionnaire scores (P=0.017) and a higher prevalence of cardiovascular diseases (P=0.012) comparing with women without sexual dysfunction. Age was an independent predictive factor for developing erectile dysfunction in men (relative risk=1.26; P=0.033) and sexual dysfunction in women (relative risk =1.30; P=0.039), regardless of DBS-STN submission. CONCLUSIONS Sexual function in both sexes of patients with PD does not seem to be influenced by DBS-STN itself, but by psychological and clinical features.

Abstract
Parkinson's disease (PD) is a neurodegenerative disease with a 200 year-long research history. Our understanding about its clinical phenotype and pathogenesis remains limited, although dopaminergic replacement therapy has significantly improved patient outcomes. Autonomic dysfunction is an essential category of non-motor phenotypes that has recently become a cutting edge field that directs frontier research in PD. In this review, we initially describe the epidemiology of dysautonomic symptoms in PD. Then, we perform a meticulous analysis of the pathophysiology of autonomic dysfunction in PD and propose that the peripheral autonomic nervous system may be a key route for α-synuclein pathology propagation from the periphery to the central nervous system. In addition, we recommend that constipation, orthostatic hypotension, urinary dysfunction, erectile dysfunction, and pure autonomic failure should be viewed as prodromal dysautonomic markers in PD prediction and diagnosis. Finally, we summarize the strategies currently available for the treatment of autonomic dysfunction in PD and suggest that high-quality, better-designed, randomized clinical trials should be conducted in the future.

Abstract
BACKGROUND AND PURPOSE Data suggest a relationship between sexual dysfunction, mainly erectile dysfunction in men, and worse disease progression in Parkinson's disease (PD). There is scant evidence on the correlates of sexual activity in PD patients. By involving a subgroup of 355 patients from the PRIAMO (Parkinson Disease Non Motor Symptoms) study, the present 24-month longitudinal prospective analysis aims to demonstrate that the presence of active sexual life is associated with disease progression in early PD. METHODS AND RESULTS Multivariable mixed-effect logistic regression models showed that gastrointestinal symptoms [odds ratio 0.56, 95% confidence interval (CI) 0.39-0.82, P = 0.003] and apathy (odds ratio 0.42, 95% CI 0.29-0.63, P < 0.001) were less likely to be associated with sexual activity in men. Analysis also demonstrated that sexual activity in men was associated with lower motor disability (coefficient -2.881, 95% CI -4.732 to -1.030, P = 0.002), better quality of life (coefficient -24.196, 95% CI -44.884 to -3.508, P = 0.022; coefficient 0.083, 95% CI 0.023-0.143, P = 0.006) and lower depression scores (coefficient -1.245, 95% CI -2.104 to -0.387, P = 0.004). No association was shown in women. CONCLUSIONS This is the first prospective longitudinal study involving a large cohort of PD patients suggesting that sexual activity is associated with lower motor and non-motor disability as well as with better quality of life in men. These findings should prompt movement disorders specialists to periodically inquiry about their patients' sexual life.

Abstract
Sexuality and intimacy are poorly researched in both people living with Parkinson's and in older people. Triggers for discussion usually centre on sexual dysfunction and hypersexuality in relation to Parkinson's. However, there are many more factors that impact on physical and emotional connectedness. Despite highlighting this unmet need there are limited tools or comprehensive assessments available to help improve quality of life. Further research is required within this field, with emphasis on health professionals' education and on highlighting to patients that they have permission for this topic to be discussed and actioned.

Abstract
Background Patients with Parkinson disease (PD) and their partners report deterioration in their sexual life. Sexual dysfunction (SD), an important and often ignored aspect, is common in PD. Motor and nonmotor symptoms are involved in limiting pleasure and disturbing function. Sexual dissatisfaction is more common in men that in women. Frequently, both patients and partners have SD associated with PD, and both need suitable treatment. These issues need to be evaluated by neurologists or PD nurses and by specialized sex therapists. The objectives of this study were to describe the complexity and multidimensional nature of sexual problems in PD, enable practitioners to assess and treat sexual difficulties of their patients, and increase awareness of the role of sex therapy in the therapeutic process of PD. Methods Based on clinical experience of over 30 years in movement disorder clinics and a review of the literature, the authors suggest practical approaches, including an "Open Sexual Communication" module, prescribing medications, and/or referring to specialists. Results and Discussion The longitudinal nature of treating neurologic patients puts physicians in an important position to introduce sexual issues and to assess and plan the interventions and follow-up needed to ensure that sexual difficulties are resolved. The management of hypersexuality requires a thoughtful distinction between lack of opportunities for sexual expression, limited ability to perform, and true hypersexuality. Sex therapists have a major role in the assessment and treatment of the multiple factors that may underlie sexual dissatisfaction in PD, differentiating between hypersexual behaviors and other sexual preoccupation behaviors, and training the professional team.

Abstract
CONTEXT Impaired sexual function has a significant effect on quality of life. Various patient-reported outcome measures (PROMs) are available to evaluate sexual function. The quality of the PROMs to be used for neurologic patients remains unknown. OBJECTIVE To systematically review which validated PROMs are available to evaluate sexual function in neurologic patients and to critically assess the quality of the validation studies and measurement properties for each identified PROM. EVIDENCE ACQUISITION A systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. The included publications were assessed according to the Consensus-Based Standards for the Selection of Health Measurement Instruments checklist. EVIDENCE SYNTHESIS Twenty-one studies for PROMs regarding sexual function were identified for the following patient groups: spinal cord injury (11 studies), multiple sclerosis (MS; 6 studies), Parkinson's disease (2 studies), traumatic brain injury (1 study), and epilepsy (1 study). The evidence for the quality of PROMs was found to be variable, and overall evaluation of measurement properties was lacking in 71% of the studies. The measurement error and responsiveness were not studied in any of the publications. CONCLUSIONS Several PROMs have been identified to evaluate sexual function in neurologic patients. Strong evidence was found only for the Multiple Sclerosis Intimacy and Sexuality Questionnaire-15 and Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 for patients with MS, although evidence was lacking for certain measurement properties as well. Future research should focus on identifying relevant PROMs and establishing adequate quality for all measurement properties in studies with high methodological quality. PATIENT SUMMARY A quality assessment of patient-reported outcome measures (PROMs) for sexual function in neurologic patients was made. The evidence found for good PROMs was limited. Studies with high methodological quality are needed to improve the quality of PROMs to evaluate sexual function in neurologic patients.

Abstract
OBJECTIVE In this study, we aimed to evaluate sexual dysfunction (SD) between two different regions of Turkey in patients with Parkinson's Disease (PD). PATIENTS AND METHODS Forty-three PD patients in Ordu and 71 patients in Istanbul were included. The Unified PD Rating Scale and Hoehn and Yahr Stage (HYS) scale were used to assess disease severity. Cognitive function was assessed by the Mini-Mental State Examination (MMSE). The sexual functions of the patients were evaluated with applying the Turkish version of the Arizona Sexual Experiences Scale (ASEX). RESULTS Mean age of patients in Istanbul was 67.25±8.34years and mean age of patients in Ordu was 67.98±8.93 (p=0.66). There was 87.33% SD in Istanbul group and 95.35% in Ordu group (p=0.20) respectively. In terms of ASEX score, no difference was found between the Istanbul and Ordu groups. ASEX scores were significantly higher in females in both groups. CONCLUSION In this study, we have found that living in the different regions of our country does not have an impact on sexual function in PD patients.

Abstract
Parkinson's disease has traditionally been considered as primarily a motor disorder (Chaudhuri & Schapira, 2009). It is clear however that it is the burden of the nonmotor symptomatology which impacts significantly more highly on caregiver burden and quality of life (Benavides, Alberquerque, & Chana-Cuevas, 2013; Martinez-Martin, 2011). As Parkinson's disease advances there is an almost inevitable accrual of nonmotor symptoms alongside the motor aspects of the disease. Patients as their disease progresses require increasing support and this is not infrequently provided by an informal caregiver, most typically a spouse or family member (Martinez-Martin, Forjaz, Frades-Payo, et al., 2007). The role of the caregiver while being emotionally, physically, and psychosocially demanding is also costly and time intensive. The cost of care is typically borne by the family and one survey has estimated that the average caregiver spends an average of 22h per week fulfilling their role. The caregiver has a unique and privileged view of the patient's condition and often due to symptoms of apathy, cognitive impairment, and depression can provide a more accurate appraisal of symptoms and treatment effect. It is therefore imperative that the caregiver is involved, where possible in clinical appointments and treatment decisions. During this chapter the impact of nonmotor symptoms on the caregiver will be highlighted and the need for early and continued collaboration with the caregiver reiterated. The influence of certain key nonmotor symptoms on caregiver burden will be explored in more detail and the narrative will be punctuated with carer reflections as experienced by Jon Hiseman while caring for his wife Barbara, a world renowned saxophonist.

Abstract
Parkinson's disease is acknowledged to be a multisystem syndrome, manifesting as a result of multineuropeptide dysfunction, including dopaminergic, cholinergic, serotonergic, and noradrenergic deficits. This multisystem disorder ultimately leads to the presentation of a range of nonmotor symptoms, now appreciated to be an integral part of the disease-specific spectrum of symptoms, often preceding the diagnosis of motor Parkinson's disease. In this chapter, we review the dopaminergic and nondopaminergic basis of these symptoms by exploring the neuroimaging evidence based on several techniques including positron emission tomography, single-photon emission computed tomography molecular imaging, magnetic resonance imaging, functional magnetic resonance imaging, and diffusion tensor imaging. We discuss the role of these neuroimaging techniques in elucidating the underlying pathophysiology of NMS in Parkinson's disease.

Parkinson's disease (PD) is now considered to be a multisystemic disorder consequent on multineuropeptide dysfunction including dopaminergic, serotonergic, cholinergic, and noradrenergic systems. This multipeptide dysfunction leads to expression of a range of non-motor symptoms now known to be integral to the concept of PD and preceding the diagnosis of motor PD. Some non-motor symptoms in PD may have a dopaminergic basis and in this review, we investigate the evidence for this based on imaging techniques using dopamine-based radioligands. To discuss non-motor symptoms we follow the classification as outlined by the validated PD non-motor symptoms scale.

Abstract
This study aimed at examining the impact of Parkinson disease (PD) on patients' sexuality and relationship and to evaluate gender-specific differences. Using a standardized questionnaire on sexual functioning in chronic diseases (SFCE), the impact of PD diagnosis on 38 domains of sexuality before and since PD diagnosis was evaluated retrospectively in 53 consecutive patients in a relationship. Changes in self-assessed ratings on a four-point Likert scale were determined for all patients. In addition, gender-specific differences and the influence of age, depression (BDI-II), medication, disease severity and disease duration on domains of the SFCE were calculated. The importance of non-sexual relational aspects, such as talking about feelings or tenderness increased for both genders after PD diagnosis, especially in women. Sexual function, such as frequency of intercourse, sexual arousal, subjective abnormal sexual fantasies or sexual satisfaction deteriorated in both genders, especially in men. Some sexual aspects improved in women but worsened in men after PD diagnosis. This includes frequency of orgasm dysfunction, fear not to fulfill sexual expectations of the partner, avoidance of sexual acts, withdrawal from relationship, increase of thoughts about divorce, or increase of dissatisfaction with sexuality and relationship. With age, thoughts about divorce declined. With disease duration, frequency of tenderness with the partner increased. Depression unexpectedly correlated with higher frequency of intercourse. Dopaminergic dosage influenced stability of the relationship negatively. PD influences patients' sexuality negatively, independently of age, disease duration or disease severity and men show greater sexual dysfunction and impairment of their sexual relationship than women.

Abstract
Mood, anxiety, and other psychological symptoms are common in dystonic patients suffering from blepharospasm (BSP) and spasmodic torticollis (ST). Since sexual well-being is an important aspect of mental health, here, we investigated whether these patients may also experience a worsening of their sexual life. In particular, quality of sexual life was evaluated in patients suffering from BSP (N = 30), ST (N = 30), and in a control group of patient with Hemifacial spasm (HFS; N = 30), undergoing botulinum toxin type A therapy. A group of 30 age-matched healthy volunteers constituted an additional control group. Patients were evaluated just before the periodic injection of botulinum toxin. Sexual functioning was assessed using the Sexual Functioning Inventory, a reduced form of the Golombok Rust Inventory, previously employed in patients with Parkinson's disease. Depression (Beck Depression Inventory) and anxiety (STAI-X1/X2) were also assessed. Results revealed that sexual functioning was significantly affected in patients with BSP, ST, and HFS with respect to healthy controls. Dystonic patients manifested more sexual dysfunction than patients with HFS. Overall, females had a poorer quality of sexual life than males and, among females, women with BSP were the most dysfunctional. Psychological symptoms were present in patients with dystonia, but not in patients with HFS. As discussed in the paper, several factors might be taken into account to explain worse quality of sexual life in patients with dystonia compared to patients with hemifacial spasm. Among them an important role might be played by the central origin of dystonia pathophysiology (i.e., altered activity of cortico-striato-thalamic-cortical circuits). Future investigations are necessary to further explore these preliminary findings, considering that this is the first time that sexual well-being is evaluated in patients with BSP, ST, and HFS, and comparable data are not available.

Abstract
PURPOSE Patients with Parkinson's disease (PD) variably report sexual dysfunctions. We assessed sexuality in PD by comparing sexual function between a large group of patients with idiopathic PD and a group of subjects without PD. METHODS We recruited 121 patients with mild-to-moderate PD (aged 40-80years) from four Italian Movement Disorder Clinics and 123 non-Parkinsonian controls (NPC) (aged 40-80years). Sexual function was assessed with four scales: the Brief Index of Sexual Functioning (BISF-M for men; BISF-W for women), the International Index of Erectile Function (IIEF), and the Female Sexual Function Index (FSFI). Both groups also underwent assessment with the Beck Depression Inventory (BDI) and the Mini Mental State Examination (MMSE), and patients were assessed with the Parkinson's Disease Questionnaire-8 (PDQ-8). RESULTS No differences in total score were found between PD and NPC for any sexual function scale (BISF-M, BISF-W, IIEF, FSFI: p>0.05). However, the Orgasm/Pleasure Domain (BISF, D5) was significantly lower in male patients than in controls. CONCLUSION Our findings fail to confirm previous findings that PD is associated with a significant sexual impairment. NPC and patients with PD have comparable sexual function in both sexes. Thus, rather than dismissing sexual dysfunction as a normal parkinsonian symptom, physicians should refer patients to sexual medicine specialists who can investigate and discuss problems fully, diagnose possible comorbidities, and suggest appropriate treatments.

Abstract
OBJECTIVE Age at onset in Parkinson's disease (PD) seems to be related nonmotor symptoms. In this study we investigated the effect of the age at onset on symptoms of sexual dysfunction (SSD) in patients with PD. METHODS This prospective study comprised 22 consecutive outpatients with early onset PD (EOPD-onset of the disease before 55 years), and 66 outpatients with late onset PD (LOPD-onset of PD over 55 years). They were all recruited from the Department of Movement Disorders, Clinic of Neurology. The diagnosis was established according to the UK PD Brain Bank Criteria by a movement disorders specialist. The Unified PD Rating Scale (UPDRS) motor was used to assess motor disability and Hoehn and Yahr (H&Y) stage was used to establish disease severity. The sexual functions of the patients were rated by applying the Arizona Sexual Experiences Scale (ASEX). RESULTS Thirteen EOPD patients (59.09 %) and 53 of the LOPD patients (80.3 %) (p 0.047) reported dissatisfaction with at least one item of ASEX. There were no differences between H&Y stages (p 0.205) UPDRS total (p 0.267) and motor scores (p 0.100) between groups. LOPD patients had significantly higher ASEX scores than EOPD patients (p 0.001). INTERPRETATION Sexual dysfunciton occurs more frequently and more severely in LOPD than EOPD patients. PD patients with different ages at onset clinically present differently in terms of SSD.

Abstract
BACKGROUND Sexual health and function is an important yet understudied aspect of overall health and well-being in older adults. There are limited data on the relative strength of associations between various aspects of sexual health with the physical, emotional, and cognitive function in older adults. Additionally, there is little information on how these associations differ by age and sex. METHODS In this Successful Aging Evaluation (SAGE) study, 606 community-dwelling adults in San Diego County, aged 50-99 years and who had a partner, were included in the analysis. Evaluations included a phone-based cognitive screening followed by a comprehensive mail-in survey including rating scales of sexual health, depression, anxiety, and physical function. RESULTS The mean age of the sample was 75.2 years. Over 80% of respondents had engaged in sexual activity in the past year, over 70% engaged in sexual activity weekly or more than once a week, and over 60% were somewhat or very satisfied with their sex lives. No sex differences were evident on dimensions of sexual health except for a higher rate of rejection of sexual overtures by women. Depressive symptoms were negatively associated with all assessed aspects of sexual health, even after adjusting for age, physical functioning, anxiety, cognitive ability, or perceived stress in both men and women. CONCLUSIONS In this population-based study older men and women who had a partner reported frequent engagement in and satisfaction with sexual activity. Depressive symptoms were broadly associated with worse sexual health, more so than physical function, anxiety or stress, or age itself.

Abstract
OBJECTIVE In this study, we aimed to find out whether sexual dysfunction in patients with Parkinson's Disease (PD) was associated to PD-related disability and whether this relationship was modulated by depressive and anxiety symptoms. METHODS Eighty-nine consecutive patients with idiopathic PD who attended to our movement disorders outpatient clinics between January 2011 and June 2014 were included in this study. The diagnosis of PD was confirmed by a movement disorders specialists in Neurology, according to UK Parkinson's Disease Society Brain Bank Criteria. The Unified PD Rating Scale (UPDRS) motor was used to assess motor disability and Hoehn and Yahr stage (H&Y) was used to establish disease severity. Cognitive function was assessed by the Mini-Mental State Examination. Patients were also administered the Hamilton depression (HAMD) and anxiety (HAMA) rating scales. The sexual functions of the patients were rated by applying the Turkish version of the Arizona Sexual Experiences Scale (ASEX). RESULTS The mean age at the time of the study visit was 67.74±9.05. Male/female ratio was 1.87. Mean UPDRS total was 29.06±13.96 and mean UPDRS motor was 17.62±9.07. Mean HAMD score was 13.92±10.86, 58.4% of the patients had minor or major depression; and mean HAMA score was 7.94±6.49, 56.2% of the patients had minor or major anxiety. The mean ASEX score was 18.54±7.27 out of a maximum of 30. ASEX total scores were correlated with age, H&Y stage and HAMA scores. Age and also age at onset were correlated with ASEX subdomains except sexual desire. There was no correlation between disease duration and ASEX subdomains. UPDRS motor score was correlated with erection/lubrication. HAMD was only correlated with orgasm satisfaction. HAMA score was correlated with stimulation and orgasm. CONCLUSION In patients with PD, there may be a common factor that modulates both depression, anxiety and sexual function. Further studies are needed to clarify the exact relationship.

Abstract
Sexual dysfunction (SD) is common among patients with Parkinson's disease (PD), Alzheimer's disease (AD), and other dementias. Sexual functioning and well-being of patients with PD and their partners are affected by many factors, including motor disabilities, non-motor symptoms (e.g., autonomic dysfunction, sleep disturbances, mood disorders, cognitive abnormalities, pain, and sensory disorders), medication effects, and relationship issues. The common sexual problems are decreased desire, erectile dysfunction, difficulties in reaching orgasm, and sexual dissatisfaction. Hypersexuality is one of a broad range of impulse control disorders reported in PD, attributed to antiparkinsonian therapy, mainly dopamine agonists. Involvement of a multidisciplinary team may enable a significant management of hypersexuality. Data on SD in demented patients are scarce, mainly reporting reduced frequency of sex and erectile dysfunction. Treatment of SD is advised at an early stage. Behavioral problems, including inappropriate sexual behavior (ISB), are distressing for patients and their caregivers and may reflect the prevailing behavior accompanying dementia (disinhibition or apathy associated with hyposexuality). The neurobiologic basis of ISB is still only vaguely understood but assessment and intervention are recommended as soon as ISB is suspected. Management of ISB in dementia demands a thorough evaluation and understanding of the behavior, and can be treated by non-pharmacologic and pharmacologic interventions.

Abstract
Nonmotor symptoms, among them sexual dysfunction, are common and underrecognized in patients with Parkinson disease; they play a major role in the deterioration of quality of life of patients and their partners. Loss of desire and dissatisfaction with their sexual life is encountered in both genders. Hypersexuality (HS), erectile dysfunction and problems with ejaculation are found in male patients, and loss of lubrication and involuntary urination during sex are found in female patients. Tremor, hypomimia, muscle rigidity, bradykinesia, 'clumsiness' in fine motor control, dyskinesias, hypersalivation and sweating may interfere with sexual function. Optimal dopaminergic treatment should facilitate sexual encounters of the couple. Appropriate counselling diminishes some of the problems (reluctance to engage in sex, problems with ejaculation, lubrication and urinary incontinence). Treatment of erectile dysfunction with sildenafil and apomorphine is evidence based. HS or compulsive sexual behaviour are side effects of dopaminergic therapy, particularly by dopaminergic agonists, and should be treated primarily by diminishing their dose. Neurologists should actively investigate sexual dysfunction in their Parkinsonian patients and offer treatment, optimally within a multidisciplinary team, where a dedicated professional would deal with sexual counselling.

Abstract
INTRODUCTION This research deals with the topic of sexual life among people suffering from Parkinson's disease (PD) and with selected factors related to sexual functioning in these patients. Parkinson's disease is a serious chronic disease whose symptoms as well as treatment substantially affect the sexual life of the patients. Despite this fact, very little published work has dealt with this topic. AIM This research focuses on describing the structure of deterioration of sexual functions of the patients suffering from PD, and statistical analysis of the interdependence of selected factors (age, duration of the disease, subjective score of the impact of the disease, depression, anxiety) as well as the patients' sexual satisfaction. The most substantial factors influencing sexual satisfaction of men and women with PD are analysed and their impact assessed, the greatest stress being put on psychiatric factors. METHODS The research project examined a group of 103 people with PD. In order to identify the specifics of the patients' sexual lives, two questionnaire-sets were designed (separate for men and women), containing psychological (BDI-II, STAI) and sexological (FSFI, IIEF, GRISS) questionnaires. MAIN OUTCOME MEASURES The main outcome measures were depression, state and trait anxiety, sexual satisfaction, erectile function, the Female Sexual Function Index. RESULTS The acquired data was statistically elaborated using the programme SPSS. The results of the sexological questionnaires show a decrease in overall sexual functioning and the presence of sexual dysfunctions related to PD. With the help of regression models it was elicited that in case of men with this illness, the most influential factor on their sexual life is depression and their subjective scoring of the illness, in the case of women the prevailing factors are depression and anxiety. CONCLUSIONS Sexuality for people suffering from Parkinson's disease is a very complex issue and psychiatric factors (depression, anxiety) have an important impact on the sexual functioning of the patients.

Abstract
INTRODUCTION Patients with Parkinson's disease (PD) report frequent sexual dissatisfaction, desire, arousal and orgasmic problems. Motor and non-motor symptoms contribute to further manifestations of sexual dysfunction (SD). Studies have indicated that the need for intimacy and sexual expression are important dimensions of quality of life for PD patients. Inquiry about sexual functioning may be overlooked by neurologists due to time constraints, confusion about sexual conversation, and lack of proper training. METHODS Practical strategies will be presented. "Open Sexual Communication" (OSEC) module will be used to overcome barriers for sexual discussion. Suggestion for further assessment and analysis of cases will enable understanding of specific sexual interventions adapted for PD patients. RESULTS Physicians will be empowered to address sexual problems of PD patients and encounter a range of practical interventions. CONCLUSIONS The physical and emotional changes in PD and treatment of the disease have a major effect on SD of patients and their partners. All patients may experience impairment of sexual function and quality of life. Health care providers can proactively address sexual health issues by providing information, by recognizing and treating the sexual needs of PD patients and by referring them to specialists.

Abstract
INTRODUCTION Parkinson's disease (PD) presents unique personal and social challenges, particularly for those with onset before the age of 50 years. AIM The aim of this article is to evaluate sexual and non-sexual aspects of relationship satisfaction among persons with young-onset PD and their partners. MAIN OUTCOME MEASURES The main outcome measures were Index of Sexual Satisfaction (ISS) and Golombok-Rust Inventory of Marital State (GRIMS). METHODS Persons with PD (PWP) and partners who attended the 2005 National Parkinson Foundation Young Onset Network Conference were asked to complete a survey. Each survey included demographics, a clinical history questionnaire, the Beck Depression Inventory (BDI), ISS, and GRIMS. RESULTS Sixty PWP (63% men, 85% in a relationship) responded to the survey. Median age was 50 years (range 29-62), with a median age at symptom onset of 43 years (range 17-55). ISS scores indicated clinically significant sexual dissatisfaction in 37%. Relationship dissatisfaction measured by the GRIMS was scored as "poor" or worse in 57%. Depressive symptomatology was severe in 19% and mild in 33%. Sexual dissatisfaction (ISS) correlated with relationship dissatisfaction (GRIMS) (correlation coefficient [CC] = 0.58, P < 0.001). Relationship dissatisfaction (GRIMS) correlated with depressive symptomatology (BDI) (CC = 0.38, P = 0.007). No correlations were found with any demographic or disease characteristics. Thirty-two couples (both the PWP and their partner) completed the surveys. Sexual and relationship dissatisfaction among PWP paralleled that of their partner (ISS: CC = 0.48, P = 0.005; GRIMS: CC = 0.61, P < 0.001). Depressive symptomatology of the PWP correlated with their partners' relationship dissatisfaction (CC = 0.46, P = 0.010). CONCLUSIONS In this study, sexual and relationship dissatisfaction were prevalent among young-onset PD patients. PD patients were similar to their partners in their level of sexual and relationship dissatisfaction. The degree of dissatisfaction did not correlate with demographics or self-reported disease characteristics. Self-reported depressive symptomatology among PD patients was adversely associated with both their and their partner's relationship satisfaction. Wiel

Abstract
Parkinson's disease is a common progressive neurodegenerative condition with multiple motor and nonmotor features contributing to impairment of health-related quality of life (HR-QOL). Pharmacological treatments have been directed primarily at dopamine replacement with levodopa and agents to improve its bioavailability, including DOPA decarboxylase inhibitors, catechol-O-methyltransferase (COMT) inhibitors and monoamine oxidase B (MAO-B) inhibitors, as well as synthetic dopamine agonists. These treatments to restore motor function are often very successful in early Parkinson's disease, with objective improvement and concomitant improvement in subjective HR-QOL scores. However, as the disease progresses, motor complications and nonmotor symptoms predominate and are often refractory to therapeutic interventions. Antiparkinsonian medications have been shown to improve motor severity and motor complications of advancing disease, and there is increasing evidence that this can be translated into subjective improvement of HR-QOL from a patient's point of view. However, the degree of improvement is less marked on HR-QOL scores than on motor scores, and some studies do not show improvement of HR-QOL in parallel to motor improvements. A number of explanations are possible, including limitations of the scales used, trial designs and lack of clinical improvement from the patients' point of view. This review concentrates on clinical trials with an index of HR-QOL as an outcome measure, with particular emphasis on well designed, randomized, double-blind, placebo-controlled or active comparator-controlled methodology. Drugs that have been more recently added to the armamentarium of Parkinson's disease, including the oral (pramipexole, ropinirole and piribedil) and transdermal (rotigotine) non-ergotamine-derived dopamine agonists, the novel MAO-B inhibitor rasagiline and the COMT inhibitors tolcapone and entacapone, were included. The effect of each of these agents on overall HR-QOL and depression, a factor that has been shown to significantly contribute to HR-QOL in several multivariate analyses, is discussed.Overall, the literature search revealed 14 double-blind, placebo- or active comparator-controlled trials with an index of HR-QOL as an outcome measure. Entacapone resulted in HR-QOL improvement in nonfluctuating patients (one study) but not clearly in those with motor fluctuations (two studies). Tolcapone was only tested in patients with motor fluctuations and resulted in significant improvement in two of four studies using HR-QOL as an outcome measure. Rasagiline improved HR-QOL as monotherapy in early Parkinson's disease (one study), but not clearly in more advanced disease (one study). Rotigotine improved HR-QOL in both early Parkinson's disease (one study) and more advanced disease with motor fluctuations (one study). The impact of ropinirole and pramipexole on HR-QOL as monotherapy in early Parkinson's disease versus placebo has not been assessed, but both agents have resulted in improved HR-QOL in patients with motor fluctuations (ropinirole one study, pramipexole one study). The evidence for antidepressant efficacy of antiparkinsonian medications is limited.

Abstract
Sexual dysfunction is one of the more disabling and poorly investigated aspects of PD. Several variables should be considered when evaluating sexual dysfunction in a disease in which physical, psychological, neurobiological and pharmacological features merge and are not easily distinguishable. Although sexual dysfunction is common in Parkinson's disease, the development of hypersexuality and aberrant sexual behaviour, probably due to dopamine replacement therapy, calls into question the role of dopamine in sexual behaviour. This paper reviews studies that have investigated sexual behaviour and dysfunction in PD patients, paying particular attention to the effect of dopamine replacement therapy.

Abstract
The aim of this study is to appraise the suitability of current quality of life (QOL) questionnaires for use in the field of Parkinson's disease (PD). Computerized bibliographic databases were screened for publications from 1960 to December 2006. Predefined selection criteria were used to identify QOL questionnaires in PD studies. Two investigators independently assessed and, subsequently, agreed on a set of multidimensional generic and PD-specific QOL questionnaires. Data were extracted concerning the internal structure, reliability, validity, and responsiveness of the included questionnaires. Sixteen-questionnaires were found, of which 14 questionnaires were included (six generic measures and eight PD-specific). In general, the psychometrics of all the questionnaires were adequately described. Sensitivity to change, however, has been reported for only a limited number of instruments. Almost all included questionnaires used QOL as a keyword, but only two questionnaires fitted the broad QOL definition used in this review. Considering the few "real " QOL questionnaires, we conclude that there is a strong need for such instruments.

Abstract
This paper reviews the literature on health-related quality of life (Hr-QoL) and depressive disorders, and the relationship between them, in patients with Parkinson's disease (PD). PD is associated with reduced Hr-QoL, including motor and non-motor physical consequences of the disease, emotional well-being and social functioning. While this effect is greater in advanced disease stages, there is no close relationship between disease duration and impact on quality of life, and the relationship between clinical rating scales and Hr-QoL scores is only moderate. On the other hand, presence and severity of depression in PD strongly correlates with Hr-QoL scores, and a number of studies have reported depression as the main determinant of poor HR-QoL scores. Despite being the main determinant of poor Hr-QoL and being recognized as an important problem by clinicians, until recently depression in PD has received relatively little attention in research studies. It is known that depression and anxiety occur more frequently in PD than in controls. Depression occurs in a bimodal pattern in PD, with increased rates at the onset and a later peak in advanced disease. Both anxiety and depression can also occur before the first motor symptoms of PD and predate the diagnosis of PD, indicating that these co-morbidities are manifestations of the underlying disease process of PD. Imaging studies have demonstrated abnormalities of dopaminergic, noradrenergic and serotonergic functioning with some correlation with severity of depression. The overall relationship between disease severity and rate of depression (except for off-period related depression) is poor, suggesting that nigrostriatal dysfunction alone is not sufficient to explain depressive symptoms in PD. Other factors are likely to contribute to occurrence and severity of depression in PD, either due to extrastriatal pathology or due to psychological and environmental factors leading to reactive depression. Thus, it is likely that depression in PD is multifactorial. The investigation of depression in PD is complicated by diagnostic difficulties in measuring and diagnosing depression in patients with PD due to the considerable overlap between symptoms of PD and depression. While a number of treatment approaches have been suggested, double-blind randomized controlled trials to demonstrate improvement of depression and overall Hr-QoL in PD are warranted.
