Abstract
There are recent reports that alexithymia may be associated with brain dysfunction involving frontal lobes or right hemisphere regions. However, little is known about the relationship between alexithymia and cognitive deficits in Parkinson's disease (PD). The authors investigated the neuropsychological correlates of alexithymia in a population of 70 nondemented PD patients and 70 controls. Alexithymia was screened using the 20-item version of the Toronto Alexithymia Scale (TAS-20). Standardized scales that measure verbal episodic memory, executive functions, abstract reasoning, and visual-spatial and language abilities were adopted. PD patients with alexithymia performed worse than both PD patients without alexithymia and controls with or without alexithymia on tasks requiring visual-spatial processing. Moreover, regression analyses showed that, in PD patients, but not in controls, poor performance on a constructional praxis task predicted high scores on the TAS-20 subscale, which assesses difficulty in identifying emotions. These data evidence an association between alexithymia and visual-spatial processing alterations in PD patients, supporting the view that the right hemisphere could be specifically involved in the modulation of some facets of alexithymia.

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

Abstract
The objective of this study was to assess whether scores on the Beck Depression Inventory (BDI) are biased by injury severity among hospitalized survivors of burn (N=262). A confirmatory factor analysis (CFA) model was developed with a general depression factor that loaded on all items and somatic and cognitive factors that were orthogonal to the general factor and to each other. The model fit the data well and substantially better than an alternative three-factor model with correlated factors. Percent total body surface area burned (TBSA) was significantly associated with the general depression factor (p=.04), but also with the orthogonal somatic factor (p<.001), suggesting biased measurement due to overlap between somatic symptoms of depression and the severity of the burn injury. Analysis of item communalities, however, suggested that only approximately 2% of total predicted item variance was associated with bias related to injury severity. It was concluded that, despite a small amount of bias, the BDI is a reasonably accurate clinical tool even in the context of severe burn. Appropriate adjustments for bias, however, should be made in research with the BDI among patients with acute burn.

Abstract
Neuropsychiatric problems are common in Parkinson's disease (PD) but there is little information regarding how they impact on quality of life. PD patients without dementia (49) were assessed for low mood/depression, fatigue, apathy, sleep problems and hallucinations. Measures of quality of life and motor function were also obtained. Over 77% of the patients reported symptoms consistent with one or more neuropsychiatric problems. Low mood/depression, anxiety and the presence of hallucinations predicted poorer quality of life after controlling for motor symptoms. Additional to the motor symptoms, we found that specific neuropsychiatric problems may impact on quality of life for PD patients.

Abstract
Background Major depression is common after coronary artery bypass graft surgery and is associated with increased mortality and morbidity. Clinicians have few practical options for detecting depression, especially in women, who are at higher risk for depression than men.
Objectives To evaluate the clinical utility of common self-report and observer-rated instruments for detection of major depression in women after coronary artery bypass graft surgery.
Methods In 66 women being discharged after coronary artery bypass graft surgery, 4 instruments were completed: the Hamilton Depression Rating Scale, Beck Depression Inventory, Beck Depression Inventory Short Form, and Beck Depression Inventory for Primary Care. For each instrument, receiver-operating-characteristic curves were analyzed, and positive and negative predictive values were calculated for cutoff points determined from the curves.
Results At hospital discharge, all 4 instruments yielded highly accurate curves. Compared with cutoffs suggested for patients without medical illness and hospitalized nonsurgical patients, identified cutoffs for screening were higher when all types of depressive symptoms (cognitive, affective, behavioral, somatic) were measured with the Hamilton Depression Rating Scale and the Beck Depression Inventory but lower when only cognitive and/or affective symptoms were measured with the 2 subscales of the Beck Depression Inventory.
Conclusions The Hamilton Depression Rating Scale and both subscales of the Beck Depression Inventory may be useful for detecting major depression in women shortly after coronary artery bypass graft surgery. Further study is warranted to confirm cutoffs in these patients.

Abstract
Zusammenfassung. Hintergrund: Depressive Störungen und koronare Herzkrankheit (KHK) treten häufig gemeinsam auf. Zur Erkennung depressiver Störungen bieten sich Screeningfragebögen an. Fragestellung: Die vorliegende Studie untersuchte die Diskriminationsleistung des Beck-Depressions-Inventars (BDI) und von vier theoretisch abgeleiteten BDI-Subskalen bei der Erkennung depressiver Störungen und depressiver Anpassungsstörungen bei KHK-Patienten. Methodik: 153 KHK-Patienten, die sich in der Hospital Anxiety and Depression Scale (HADS) als psychisch belastet beschrieben haben, wurden durch ein klinisches Interview diagnostiziert und füllten das BDI aus. Die Daten wurden in Receiver-Operating-Characteristics-Analysen ausgewertet. Ergebnisse: Bei 60 Patienten wurde eine affektive Störung bzw. eine depressive Anpassungsstörung diagnostiziert. In Reliabilitätsanalysen wies das BDI als Gesamtinstrument im Vergleich zu den vier BDI-Subskalen die höchste interne Konsistenz und die höchste Diskriminationsleistung auf. Von den Subskalen zeigte die BDI Short-Form von Beck und Steer (1993) die höchste Reliabilität und die beste Diskriminationsleistung. Für einen BDI-Gesamtwert von 12 als Cut-Off ergab sich eine hohe Sensitivität, bei einem Cut-Off von 15 dagegen ein ausgeglichenes Verhältnis zwischen Sensitivität, Spezifität und dem relativen Anteil an falsch klassifizierten Personen. Ein Cut-Off-Wert von 18 wies mit großer Wahrscheinlichkeit auf das Vorliegen einer affektiven Störung oder einer depressiven Anpassungsstörung hin. Für die BDI-Short Form ergaben sich entsprechend die Cut-Off-Werte 6, 8 und 10. Schlussfolgerung: Für die Erkennung depressiver Störungen bei KHK-Patienten sind das BDI und die BDI-Short Form gut geeignet. Der von Beck (1995) für das Gesamt-BDI vorgeschlagene Schwellenwert von 18 für die Erkennung klinisch relevanter Depression lässt sich auf KHK-Patienten übertragen.

Abstract
OBJECTIVE To prospectively assess the health-related quality of life (HrQoL) in Parkinson's disease (PD) during 12 months. METHODS HrQoL was assessed in 145 PD patients using the PD-specific PDQ-39, PDQL and the generic EQ-5D. In addition, clinical rating-scales were used. RESULTS All scales showed a pronounced effect of PD. In comparison to an age-matched population the EQ-5D was considerably affected. In comparison to baseline, however, there was no significant change in the generic scale but a significant change in the sum-score of disease-specific HrQoL-scales. CONCLUSIONS Only disease-specific scales were sensitive to change. Further studies are necessary to evaluate the time-dependent change in HrQoL.

Abstract
Depression in Parkinson's disease (dPD) is difficult to diagnose because depressive symptoms can overlap with symptoms of Parkinson's disease (PD). Subject-rated scales such as the 30-item Geriatric Depression Scale (GDS) may be useful in screening for dPD. There were 57 patients (33 men, 24 women; mean age, 58.6 years [SD +/- 8.4]) enrolled in a study of pallidotomy for intractable PD who were evaluated for depression before and after surgery. Subjects were evaluated using the 17-item Hamilton Depression Rating Scale (HDRS), Structured Clinical Interview for Diagnostic and Statistical Manual-III (SCID), and the GDS. SCID was used to diagnose major depression with confirmation by an expert geropsychiatrist. Receiver-operating curves (ROC) were used to identify cutoff points with maximal discriminant validity for diagnosing dPD. A total of 213 evaluation time points were included for the 52 patients with time points that included a valid SCID diagnosis, GDS, and HDRS. A ROC established points of maximum specificity/sensitivity for the GDS at a cutoff of 9/10 (sensitivity = 0.809, specificity = 0.837, positive predictive value [PPV] = 0.584, negative predictive value [NPV] = 0.939) and for the HDRS at a cutoff of 12/13 (sensitivity = 0.810, specificity = 0.821, PPV = 0.580, NPV = 0.934). The GDS was moderately correlated with the HDRS (Pearson's r = 0.54; P < 0.001). The GDS is useful in screening for dPD. A cutoff score of 9/10 has acceptable discriminant validity for dPD, and the GDS has a moderate correlation with the HDRS in PD patients.

Abstract
OBJECTIVE To assess the prevalence, course, and predictors of depression in patients with systemic sclerosis (SSc). METHODS We conducted a comprehensive search in November 2006 of MEDLINE, PsycINFO, and CINAHL databases to identify original research studies published in any language that used a structured interview or validated questionnaire to assess major depressive disorder or clinically significant symptoms of depression in patients with SSc. The search was augmented by hand searching 26 selected journals through December 2006 and references from identified articles and reviews. Studies were excluded if only an abstract was provided or if depression was not measured by a validated method. RESULTS No studies used a structured clinical interview to assess the prevalence of major depressive disorder. The prevalence of clinically significant depressive symptoms was 51-65% based on 2 studies that used a Beck Depression Inventory (BDI) score >or=10 and 46-56% based on 2 studies that used a BDI score >or=11. These rates and those reported in 4 other studies that used different assessment tools (36-43%) were consistently high compared with other medical patient groups assessed with the same instruments and cutoffs. Methodologic issues limited the ability to draw strong conclusions from studies of predictors. CONCLUSION Symptoms of depression are common among patients with SSc. The high rates reported across studies suggest that routine screening is recommended. There is a need for studies that examine depression at different time points from the diagnosis of SSc and that systematically investigate factors associated with high levels of depressive symptoms.

Abstract
Zusammenfassung: Ein erheblicher Anteil an Patienten mit einer idiopathischen Parkinson-Erkrankung (PD) entwickelt im Verlauf eine sekundäre Depression. Die Prävalenzraten schwanken erheblich, da die Diagnosestellung aufgrund von Symptomüberschneidungen zwischen neurologischer Grunderkrankung und Major Depression (MD) erschwert ist. Dies führt zu Problemen bei der therapeutischen Indikationsstellung sowie zu einer eingeschränkten Interpretierbarkeit neuropsychologischer und neurophysiologischer Studien. Ein weiterer Aspekt bezieht sich auf Gemeinsamkeiten und Unterschiede zwischen sekundärer und primärer Depression. Entgegen dem klinischen Eindruck einer PD-spezifischen Depression erbrachten psychometrische Verfahren zur Depressionsdiagnostik diesbezüglich bisher nur unbefriedigende Ergebnisse. Ziele dieses Überblicksartikels: 1. Charakterisierung depressiver Syndrome bei der PD, 2. Überblick über den Forschungsstand zur Neuropathologie und Neuropsychologie, 3. Gegenüberstellung klinisch- und/oder neuropsychologischer Gemeinsamkeiten/Unterschiede zwischen sekundärer und primärer MD und 4. Konsequenzen für Forschung und Differenzialdiagnostik.

Abstract
Studies investigating the assessment of depression in Parkinson's disease (PD) are limited. We examined the concurrent validity and the internal consistency of the Hamilton Depression Inventory (HDI) and compared it to the Hamilton and Geriatric Depression Scales. PD patients (n = 79) were recruited from neurology clinics. Diagnosis of depressive disorder was made according to DSM-IV criteria. Receiver operating characteristic curves were used to calculate sensitivity, specificity, and positive and negative predictive values. The HDI exhibited an optimal cutoff for discriminating between depressed and nondepressed PD patients of 13.5/14.0 and is a valid instrument to use in the setting of PD.

Abstract
INTRODUCTION Although a great number of depressive scales were developed during the last decades, there are only a few studies that compare them in terms of reliability and validity. The current study aimed to compare the properties of some of the most popular of these scales. MATERIALS AND METHODS The study sample included 40 depressed patients 29.65+/-9.38 years old, and 120 normal comparison subjects 27.23+/-10.62 years old. The clinical diagnosis was reached by consensus of two examiners with the use of the SCAN v.2.0. The scales compared were the CES-D, ZDRS, BDI-I, and the KSQ. The STAI, the Life Change Scale (Holms and Rahe), and the EPQ were also administered. The analysis included the comparison of psychometric properties and the use of Pearson correlation coefficient and factor analysis. RESULTS The results suggested that no scale was clearly superior to the others. All scales correlated to anxiety measurements, sociodemographic variables, personality dimensions and non-specific indices. The results reported here include an appendix with algorithms that help transforming one scale score into other scales scores. These algorithms can be useful for comparison purposes in meta-analytic studies. DISCUSSION The comparison of several depressive scales provided no impressive results on the superiority or inferiority of a specific scale in comparison to the others.

Abstract
This paper shows how decision theory can be used to determine optimal cut-off scores on mental health screeners. The procedure uses (a) the costs and benefits of correct and erroneous decisions, and (b) the rates of correct and erroneous decisions as a function of the cut-off score. Using this information, for each cut-off point expected costs are calculated. The cut-off point with the lowest expected costs is the optimal cut-off score. An illustration is given in which the General Health Questionnaire is employed as a major depression screener. Optimal cut-off points are determined for four different contexts: patients, health service providers, society, and mental health researchers. As in these four situations different costs are encountered, different optimal cut-off points were found.

Abstract
We have previously reported that acute dopaminergic blockade in healthy volunteers results in a transient disruption of the recognition of facial expressions of anger, whilst leaving intact the recognition of other facial expressions (including fear and disgust) and facial identity processing. Parkinson's disease (PD) is characterised by cell loss in dopaminergic neuronal populations, and hence we predicted that PD would be associated with impaired anger recognition. We reasoned that treatment with dopamine replacement therapy (DRT) could mask any deficit present in PD, and therefore studied facial expression recognition in a group of PD patients transiently withdrawn from DRT. Seventeen PD patients were compared to 21 age- and IQ-matched controls on the Ekman 60 task, which required the forced-choice labelling of 10 exemplars of each of six facial expressions (anger, disgust, fear, sadness, happiness, surprise). In line with our predictions, PD patients showed a selective impairment in the recognition of facial expressions of anger. This deficit was not related to the PD patients' performance on the Benton unfamiliar-face matching task, which was normal, nor was the deficit related to overall disease severity, or to depression symptoms. However, as predicted by simulation theories, impaired anger recognition in PD was related to reduced levels of the anger-linked temperament trait, exploratory excitability. The results extend our previous findings of a role for dopamine in the processing of facial expressions of anger, and demonstrate the power of adopting a phylogenetic, comparative perspective on emotions.

Abstract
Parkinson's disease is primarily considered a motor disease characterized by rest tremor, rigidity, bradykinesia and postural disturbances. However, neuropsychiatric complications, including mood and anxiety disorders, fatigue, apathy, psychosis, cognitive impairment, dementia, sleep disorders and addictions, frequently complicate the course of the illness. The pathophysiologic features of these complications are multifaceted and include neuropathophysiologic changes of a degenerative disease, exposure to antiparkinsonian treatments and emotional reactions to having a disabling chronic illness. Changes in mental status have profound implications for the well-being of patients with Parkinson's disease and of their caregivers. Treatment is often efficacious but becomes a challenge in advanced stages of Parkinson's disease. In this article, we review the key clinical features of neuropsychiatric complications in Parkinson's disease as well as what is known about their epidemiologic characteristics, risk factors, pathophysiologic features and management.

Abstract
Although multiple system atrophy (MSA) is a neurodegenerative disorder leading to progressive disability and decreased life expectancy, little is known about patients' own evaluation of their illness and factors associated with poor health-related quality of life (Hr-QoL). We, therefore, assessed Hr-QoL and its determinants in MSA. The following scales were applied to 115 patients in the European MSA-Study Group (EMSA-SG) Natural History Study: Medical Outcome Study Short Form (SF-36), EQ-5D, Beck Depression Inventory (BDI), Mini-Mental state examination (MMSE), Unified MSA Rating Scale (UMSARS), Hoehn & Yahr (H&Y) Parkinson's disease staging scale, Composite Autonomic Symptom Scale (COMPASS), and Parkinson's Disease Sleep Scale (PDSS). Forty-six percent of patients had moderate to severe depression (BDI > or = 17); Hr-QoL scores on the SF-36 and EQ-5D were significantly impaired. Pain, the only domain with similar scores in MSA and published PD patients, was reported more frequently in patients with MSA-P (predominantly parkinsonian motor subtype) than MSA-C (predominantly cerebellar motor subtype; 76% vs. 50%; P = 0.005). Hr-QoL scores correlated most strongly with UMSARS motor, COMPASS, and BDI scores but not with MMSE scores, age at onset, or disease duration. The COMPASS and UMSARS activities of daily living scores were moderate-to-strong predictors for the SF-36 physical summary score and the BDI and UMSARS motor scores for the SF-36 mental summary score. This report is the first study to show that Hr-QoL is significantly impaired in MSA. Although not all possible factors related to impaired Hr-QoL in MSA could be assessed, autonomic dysfunction, motor impairment, and depression were most closely associated with poor Hr-QoL, and therapeutic management, therefore, should concentrate upon these aspects of the disease.

Abstract
OBJECTIVE To determine whether plasma homocysteine (Hcy) levels are associated with clinical characteristics, neuropsychological and psychiatric manifestations and cardiovascular comorbidity in patients with Parkinson disease (PD). BACKGROUND Elevated Hcy levels are linked to atherosclerosis, vascular disease, depression, and dementia. Patients with PD treated with L-dopa have been shown to have elevated Hcy levels. DESIGN/METHODS Idiopathic PD patients were evaluated using the Unified Parkinson's Disease Rating Scale, Hoehn and Yahr stage, Parkinson Psychosis Rating Scale, Beck Depression Inventory, Frontal Assessment Battery, Mini-Mental Status Examination, and several tests for frontal type cognitive functions. Fasting blood samples were collected for the measurement of Hcy, and carotid B-mode ultrasound was performed to measure intima-media thickness of the common carotid arteries. RESULTS Seventy-two consecutive PD patients (46 men; average age, 68.7 +/- 11.6 years; average disease duration, 7.0 +/- 4.7 years) were recruited. All but 10 patients were treated with L-dopa. The average level of Hcy was 16.4 +/- 7.8 micromol/L, and 38.9% of the patients had Hcy level above the reference range (>15.0 micromol/L). The Hcy levels were associated with PD duration as they were with L-dopa treatment duration but were not associated with the parameters of disease severity or with L-dopa dose. The Hcy levels were associated neither with the common carotid intima-media thickness nor with cardiovascular morbidity. No association was found between Hcy and the neuropsychiatric features of PD such as depression, cognitive performance, or psychosis. CONCLUSIONS Hyperhomocystinemia is common in L-dopa-treatedPD patients but was not associated with neuropsychological complications (depression, dementia, and cognitive decline associated with frontal lobe functioning or psychosis), enhanced disease severity, or vascular comorbidity.

Abstract
We evaluated the validity, reliability, and potential responsiveness of the Beck Depression Inventory (BDI) in patients with Parkinson's disease (PD). In part 1 of the study, 92 patients with PD underwent a structured clinical interview for DSM major depression and based on this patients were considered depressed (PD-D) or nondepressed (PD-ND). Subsequently, patients filled in the BDI. In part 2, a postal survey consisting the BDI was performed in 185 PD patients and 112 controls. Test-retest reliability was assessed in 60 PD patients. The factor analysis revealed a cognitive-affective and a somatic factor. Cronbachs alpha for the BDI was 0.88. Mean BDI indicated significant differences (P<0.001) between the PD and control group, between the PD-ND and PD-D group, and between PD-ND and control group. In part 1, the receiver operating characteristic curves showed that the area under the curve for the total BDI was 0.88. A cutoff was calculated for the BDI (14/15) that had the highest sum of sensitivity (0.71) and specificity (0.90). In part 2, the test-retest reliability for the BDI total score was 0.89 (intraclass correlation coefficient). The smallest real difference was 3.3 for the total BDI. The BDI is a valid, reliable, and potential responsive instrument to assess the severity of depression in PD. However, an adjusted cutoff is recommended.

Abstract
Patients with Parkinson's disease (PD) frequently complain of sleep problems. These can be due to several factors, and the approach to their management depends on careful consideration of the various possible factors in each case. 1. Older people, in general, require less sleep. After retirement, people may also engage in less physical activity, and this factor is of course even more pronounced in patients with PD because of their illness. 2. Daytime naps, either spontaneous or due to drugs, reduce the need for nocturnal sleep. Explanation of these physiological and circumstantial changes may help those PD patients who manifest these consequences. 3. The existence of a severe progressive disease as well as social isolation have psychologic consequences, such as anxiety and depression, that may manifest as insomnia. Furthermore, depression is part of the disease, frequently antedating the motor manifestations, and may manifest as insomnia. 4. In advanced disease, patients may be immobile and have difficulty in getting up or even turning in bed. This causes great inconvenience, and may impair sleep. Long acting anti-Parkinson drugs such as cabergoline or rotigotine patch may help. 5. In some cases, unpleasant hallucinations may appear which prevent the patient from falling asleep. These may respond to atypical neuroleptics. Clozapine and quetiapine are particularly useful, but require attention to possible adverse effects.

Abstract
PURPOSE OF REVIEW Depressions are a heterogeneous group of conditions that contribute significantly to impairments in quality of life, independent of the severity of neurological illness. Depression may predate neurological signs and symptoms in the evolution of neurodegenerative disorders, and there is some evidence that depressive illness itself may be a risk factor in the aetiology of some dementias. This review aims to summarize the relevant current literature on diagnosis, aetiology and treatment of depression in neurology. RECENT FINDINGS Diagnosing depression in neurological conditions can be particularly difficult because of communication difficulties and changes in emotional expression as a result of the underlying neurological disease. Rating scales loaded towards somatic symptoms can show poor validity for screening or rating of severity in this setting. The evidence for the treatment of depression in neurological disease is scant, and often the treatment advice is based on consensus views of clinicians. Nevertheless, there have been some clinical trials, which are reported. SUMMARY Depression is common in neurology. It is underrecognized and undertreated. Recent research has allowed us to define depression more clearly in this setting. Trials of treatment are urgently needed, especially as depression is a significant factor in quality of life and may affect prognosis.

Abstract
AIMS/HYPOTHESIS We compared the screening performance of different measures of depression: the standard clinical assessment (SCA); the Beck Depression Inventory (BDI); the Center of Epidemiological Studies-Depression Scale (CES-D); and the Problem Areas in Diabetes (PAID) questionnaire, which assesses diabetes-specific distress. We also studied the ability of these measures to detect diabetes-related distress. MATERIALS AND METHODS A total of 376 diabetic patients (37.2% type 1; 23.9% type 2 without insulin treatment, 38.8% type 2 with insulin) completed the BDI and CES-D; patients who screened positive participated in a diagnostic interview, the Composite International Diagnostic Interview (CIDI). Also, all patients completed the PAID questionnaire. Results of the SCA that related to depression diagnosis were reviewed to correct for false negative screening results. RESULTS The prevalence of clinical depression was 14.1%, with an additional 18.9% of patients receiving a diagnosis of subclinical depression. Sensitivity for clinical depression in SCA (56%) was moderate, whereas BDI, CES-D and the PAID questionnaire showed satisfactory sensitivity (87, 79 and 81%, respectively). For subclinical depression, the sensitivity of the PAID questionnaire (79%) was sufficient, whereas that of SCA (25%) was poor. All methods showed low sensitivity for the detection of diabetes-specific emotional problems (SCA 19%, CIDI 34%, BDI 60%, CES-D 49%). CONCLUSIONS/INTERPRETATION The screening performance of SCA for clinical and subclinical depression was modest. Additional screening for depression using the PAID or another depression questionnaire seems reasonable. The ability of depression screening measures to identify diabetes-related distress is modest, suggesting that the PAID questionnaire could be useful when screening diabetic patients for both depression and emotional problems.

Abstract
INTRODUCTION Quantitative sensory testing has demonstrated a promising link between experimentally determined pain sensitivity and clinical pain. However, previous studies of quantitative sensory testing have not routinely considered the important influence of psychological factors on clinical pain. This study investigated whether measures of thermal pain sensitivity (temporal summation, first pulse response, and tolerance) contributed to clinical pain reports for patients with chronic low back pain, after controlling for depression or fear-avoidance beliefs about work. METHOD Consecutive patients (n=27) with chronic low back pain were recruited from an interdisciplinary pain rehabilitation program in Jacksonville, FL. Patients completed validated self-report questionnaires for depression, fear-avoidance beliefs, clinical pain intensity, and clinical pain related disability. Patients also underwent quantitative sensory testing from previously described protocols to determine thermal pain sensitivity (temporal summation, first pulse response, and tolerance). Hierarchical regression models investigated the contribution of depression and thermal pain sensitivity to clinical pain intensity, and fear-avoidance beliefs and thermal pain sensitivity to clinical pain related disability. RESULTS None of the measures of thermal pain sensitivity contributed to clinical pain intensity after controlling for depression. Temporal summation of evoked thermal pain significantly contributed to clinical pain disability after controlling for fear-avoidance beliefs about work. CONCLUSION Measures of thermal pain sensitivity did not contribute to pain intensity, after controlling for depression. Fear-avoidance beliefs about work and temporal summation of evoked thermal pain significantly influenced pain related disability. These factors should be considered as potential outcome predictors for patients with work-related low back pain. SIGNIFICANCE This study supported the neuromatrix theory of pain for patients with CLBP, as cognitive-evaluative factor contributed to pain perception, and cognitive-evaluative and sensory-discriminative factors uniquely contributed to an action program in response to chronic pain. Future research will determine if a predictive model consisting of fear-avoidance beliefs and temporal summation of evoked thermal pain has predictive validity for determining clinical outcome in rehabilitation or vocational settings.

Abstract
Although Parkinson disease (PD) is primarily considered a movement disorder, the high prevalence of psychiatric complications suggests that it is more accurately conceptualized as a neuropsychiatric disease. Affective disorders, cognitive impairment, and psychosis are particularly common in PD and are associated with excess disability, worse quality of life, poorer outcomes, and caregiver distress. Yet, in spite of this and their frequent occurrence, there is incomplete understanding of the epidemiology, phenomenology, risk factors, neuropathophysiology, and optimal treatment strategies for these disorders. Psychiatric complications are typically comorbid, and there is great intra- and inter-individual variability in presentation. The hallmark neuropathophysiological changes that occur in PD plus the association between exposure to dopaminergic medications and certain psychiatric disorders suggest a neurobiological basis for most psychiatric symptoms, although psychological factors are probably involved in the development of affective disorders. Although antidepressants, antipsychotics, and cognition-enhancing agents are commonly prescribed in PD, controlled studies demonstrating efficacy and tolerability of these drugs are virtually nonexistent. Because of the high prevalence and complexity of psychiatric complications in PD, geriatric psychiatrists are in a position to offer valuable consultation and clinical care to this population. This article provides an overview of the epidemiology, pathophysiology, clinical presentation, and management of the most common psychiatric complications in PD.

Abstract
OBJECTIVE The objective of this study was to compare the sensitivity, specificity, and diagnostic accuracy of the 15-item Geriatric Depression Scale (GDS-15) and the Hamilton Depression Rating Scale (HDRS) in patients with Parkinson disease (PD). METHOD A convenience sample of 148 outpatients with idiopathic PD receiving specialty care completed the GDS-15 and were administered the HDRS and Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID) depression module by a research psychiatrist or trained research assistant. Receiver-operating characteristic (ROC) curves were plotted for the GDS-15 and HDRS scores with a SCID diagnosis of a depressive disorder as the state variable. RESULTS Thirty-two subjects (22%) were diagnosed with a depressive disorder. The discriminant validity of the GDS-15 and HDRS were both high (ROC area under the curve: 0.92 and 0.91, respectively), with greatest dichotomization for the GDS-15 at a cutoff of 4/5 (87% accuracy, 88% sensitivity, 85% specificity) and the HDRS at a cutoff of 9/10 (83% accuracy, 88% sensitivity, 78% specificity). CONCLUSIONS The GDS-15 performs well as a screening instrument and in distinguishing depressed from nondepressed patients in PD. Its test characteristics are comparable to the HDRS. Because it is a brief instrument and can be self-administered, it is an excellent depression screening tool in this population.

Abstract
Numerous factors need to be taken into account in deciding whether a patient with Parkinson's disease (PD) is a candidate for deep brain stimulation. Patient-related personal factors including age and the presence of other comorbid disorders need to be considered. Neuropsychological and neuropsychiatric concerns relate both to the presurgical status of the patient and to the potential for surgery to result in new problems postoperatively. A number of factors related to the underlying PD need to be considered, including the specific parkinsonian motor indications (e.g., tremor, bradykinesia, gait dysfunction), previous medical therapies, including benefit from current therapy and adverse effects, and past surgical treatments. Definable causes of Parkinsonism, particularly atypical Parkinsonisms, should be considered. Finally, methods of evaluating outcomes should be defined and formalized. This is a report from the Consensus on Deep Brain Stimulation for Parkinson's Disease, a project commissioned by the Congress of Neurological Surgeons and the Movement Disorder Society (MDS). The report has been endorsed by the Scientific Issues Committee of the MDS and the American Society of Stereotactic and Functional Neurosurgery. It outlines answers to a series of questions developed to address all aspects of deep brain stimulation preoperative decision-making.

Abstract
Lung cancer patients may experience greater emotional distress than patients with other cancers. Studies have shown social support to predict adjustment in other cancers, but findings among lung cancer patients have been equivocal. Coping style has been shown to predict distress among lung cancer patients, but has not been examined in the context of social support. We examined coping style and social support as predictors of depressive symptoms one week after surgery among 119 patients with non-small cell lung cancer. The Beck Depression Inventory was the primary outcome measure. Predictors included age, ECOG performance status, stage of disease, and measures of adaptive coping, less adaptive coping, Directive instrumental social support and Nondirective instrumental social support. Results indicated that 29% of lung cancer patients had scores above a standard cutoff for clinically significant depression. Results also showed that depressive symptoms were directly related to use of less adaptive coping methods and Directive instrumental social support, inversely related to age and use of adaptive coping methods, and unrelated to nondirective social support, stage of disease and performance status. Results extend previous findings by showing that adaptive coping methods are related to severity of distress, and that the benefits of social support may depend on the characteristics of that support.

Abstract
OBJECT Postoperative psychiatric symptoms have been associated with subthalamic deep brain stimulation (DBS) for Parkinson disease (PD), and preoperative psychiatric vulnerability, the effects of surgery, stimulation, medication changes, and psychosocial adjustment have been proposed as causative factors. The variables involved in whether preoperative psychiatric symptoms improve or worsen following surgery are not yet known. In the present study, preoperative psychiatric symptoms were systematically assessed in patients with PD presenting for routine preoperative psychiatric assessment. METHODS Forty consecutive patients with PD presenting for DBS were interviewed using the Mini International Neuropsychiatric Inventory. Current depressive symptoms were quantified using clinician- and patient-rated depression scales. Seventy-eight percent of patients had at least one lifetime or current Axis I psychiatric diagnosis. The prevalence of depression was 60% (95% confidence interval [CI] 45-85), psychosis 35% (95% CI 25-50), and anxiety 40% (95% CI 25-55). These prevalence rates were comparable to or greater than those in the general population of patients with PD. Twenty-three percent of patients required psychiatric treatment for current symptoms prior to being considered eligible for DBS. CONCLUSIONS As part of the selection process for surgery, members of the study population were chosen for their lack of overt dementia or other active disabling psychiatric symptomatology. The incidence rates of psychiatric disorders, including those diseases occurring in the general population affected with PD, were greater than expected. Data in the present study lead one to question the reliability of patient-rated depression scales as the sole instrument for assessing depression. The authors highlight the need for evidence-based guidelines in the management of these preoperative symptoms as well as the involvement of psychiatric personnel in the assessment and management of these symptoms.

Abstract
OBJECTIVES The aetiology of the cognitive changes seen in Parkinson's disease (PD) is multifactorial but it is likely that a significant contribution arises from the disruption of dopaminergic pathways. This study aimed to investigate the contribution of the dopaminergic system to performance on two executive tasks using (18)F-6-fluorodopa positron emission tomography ((18)F-dopa PET) in PD subjects with early cognitive changes. METHODS 16 non-demented, non-depressed PD subjects were evaluated with the Tower of London (TOL) spatial planning task, a verbal working memory task (VWMT) and (18)F-dopa PET, all known to be affected in early PD. Statistical parametric mapping (SPM) localised brain regions in which (18)F-dopa uptake covaried with performance scores. Frontal cortical resting glucose metabolism was assessed with (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) PET. RESULTS SPM localised significant covariation between right caudate (18)F-dopa uptake (Ki) and TOL scores and between left anterior putamen Ki and VWMT performance. No significant covariation was found between task scores and (18)F-dopa Ki values in either limbic or cortical regions. Frontal cortical glucose metabolism was preserved in all cases. CONCLUSIONS These findings support a causative role of striatal dopaminergic depletion in the early impairment of executive functions seen in PD. They suggest that spatial and verbal executive tasks require integrity of the right and left striatum, respectively, and imply that the pattern of cognitive changes manifest by a patient with PD may reflect differential dopamine loss in the two striatal complexes.

Abstract
OBJECTIVE To assess the validity, responsiveness, and test-retest reliability of DISCs (Depression Intensity Scale Circles) as a simple screening tool for depression in patients with cognitive or communicative deficits following acquired brain injury. DESIGN Cohort analysis of consecutive patients entered into an integrated care pathway for screening and management of depression in the context of rehabilitation. SETTING Regional neurological rehabilitation service in the UK. PARTICIPANTS 114 patients with complex disabilities caused by acquired brain injury (mean (SD) age, 42.8 (14.5) years). MAIN OUTCOME MEASURES DISCs (a graphic rating scale depicting six circles with increasing proportion of dark shading), Numbered Graphic Rating Scale (NGRS), Yale single question ("Do you often feel sad or depressed"), Beck Depression Inventory-II (BDI-II), DSM-IV criteria for depression. RESULTS At initial assessment the DISCs correlated with total BDI-II scores (Spearman rho = 0.66, p < 0.001), NGRS (rho = 0.87, p<0.001), and DSM-IV (rho = 0.59, p<0.001). A DISCs score > or =2 identified depression (major or minor) according to DSM-IV criteria with 60% sensitivity, 87% specificity, 75% positive predictive value, and 77% negative predictive value. Test-retest reliability after 24 hours (n = 66) showed "excellent" level of agreement (weighted kappa = 0.84). In 45 patients who received intervention for depression, the DISCs showed a significant change in response to treatment (Wilcoxon; p<0.001). CONCLUSIONS DISCs had acceptable convergent validity, reliability, and responsiveness as a simple graded tool for screening and assessment of depression in patients with complex disabilities following acquired brain injury. It warrants further investigation in patients with more profound language and cognitive deficits for which it is primarily intended.

Abstract
OBJECTIVE The aim of this study was to examine the performance of three commonly used depression rating scales in a hospital sample of patients with chronic fatigue syndrome (CFS). METHODS Sixty-one patients with CDC criteria for CFS completed the General Health Questionnaire (GHQ), the Hamilton Depression Scale (HAM-D) and the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). Current psychiatric status was assessed using the Structured Clinical Interview for DSM-III-R. DISORDERS: Patient version (SCID-P). Receiver operating curves were drawn for each of the depression rating scales. RESULTS Thirty-one percent of the patients were depressed according to the SCID-P. Using the standard cut-offs, both GHQ and HAM-D overestimated the number of depressed patients, whilst the HADS-D underestimated the number. The receiver operating curves suggest that the optimum cut-offs for GHQ, HAM-D and HADS-D in this population are 7/8, 13/14 and 8/9, respectively. CONCLUSIONS Standard cutoffs may not be appropriate when using depression rating scales in CFS patients in a tertiary care setting.

Abstract
BACKGROUND Depression impairs psychosocial and occupational functioning and contributes to significant morbidity and mortality. Hemifacial spasm (HFS) causes social embarrassment and visual and verbal disability. OBJECTIVE We examined; (1) the prevalence and predictive factors of depressive symptoms (Becks Depression Inventory (BDI) and clinical assessment) in HFS and (2) the sensitivity and specificity of BDI as a screening and diagnostic tool in HFS. METHODS A large cohort of HFS patients in a movement disorders clinic was clinically evaluated and the BDI self-administered by patients. Univariate analysis and multivariate logistic regression were undertaken to investigate the effect of age, gender, body-mass index, duration and severity of HFS on the outcome of BDI score. ROC (receiver operating characteristics) analysis was utilized to evaluate the sensitivity and specificity and discriminative property of the scale. RESULTS There were 90 HFS patients with a mean age of 54.4+11.1 (35-79) years, comprising of 58.9% women and with a mean severity HFS score of 2.9+0.8 (range 1-4). The mean BDI score was higher in depressed HFS than in non-depressed HFS (19.7+6.7 vs 4.2+4.9, p<0.0001). Female gender and a younger age were risk factors (p=0.07). In the multivariate analysis, the severity of HFS was an independent predictor of BDI scores (p<0.0001). The AUC was 97.1% suggesting excellent discriminative property of BDI. For cut-off score of 12/13, the sensitivity was 93.3%, specificity 94.7%, Positive Predictive Value 77.8% and Negative Predictive Value 98.6%. CONCLUSIONS The prevalence of depressive disorder in HFS was 16.7%, with younger women at greater risk. The severity of HFS was positively correlated with the severity of depressive symptoms. The BDI can be a complimentary screening and/or diagnostic instrument for depressive disorder in HFS. Early diagnosis of at-risk patients will prevent unnecessary morbidity and mortality.

Abstract
Fibromyalgia is defined by widespread body pain, tenderness to palpation of tender point areas, and constitutional symptoms. The literature reports headache in about half of fibromyalgia patients. The current epidemiological study was designed to determine the prevalence and characteristics of headache in fibromyalgia patients. Treatment-seeking fibromyalgia patients were evaluated with measures for fibromyalgia, chronic headache, quality of life, and psychological distress. Multivariate analysis of variance (MANOVA) and t-tests were used to identify significant differences, as appropriate. A total of 100 fibromyalgia patients were screened (24 fibromyalgia without headache and 76 fibromyalgia with headache). International Headache Society diagnoses included: migraine alone (n = 15 with aura, n = 17 without aura), tension-type alone (n = 18), combined migraine and tension-type (n = 16), post-traumatic (n = 4), and probable analgesic overuse headache (n = 6). Fibromyalgia tender point scores and counts and most measures of pain severity, sleep disruption, or psychological distress were not significantly different between fibromyalgia patients with and without headache. As expected, the fibromyalgia patients with headache scored higher on the Headache Impact Test (HIT-6) (62.1 +/- 0.9 vs 48.3 +/- 1.6, p < 0.001). HIT-6 scores were >60 in 80% of fibromyalgia plus headache patients, representing severe impact from headache, and 56-58 in 4%, representing substantial impact. In summary, chronic headache was endorsed by 76% of treatment-seeking fibromyalgia patients, with 84% reporting substantial or severe impact from their headaches. Migraine was diagnosed in 63% of fibromyalgia plus headache patients, with probable analgesic overuse headache in only 8%. General measures of pain, pain-related disability, sleep quality, and psychological distress were similar in fibromyalgia patients with and without headache. Therefore, fibromyalgia patients with headache do not appear to represent a significantly different subgroup compared to fibromyalgia patients without headache. The high prevalence and significant impact associated with chronic headache in fibromyalgia patients, however, warrants inclusion of a headache assessment as part of the routine evaluation of fibromyalgia patients.

Abstract
OBJECTIVE To examine the concurrent validity of the Beck Depression Inventory-Short Form (BDI-SF) to detect moderate and severe depressive episodes according to the International Classification of Diseases, 10th edition (ICD-10) criteria in inpatients with heterogeneous medical conditions and to set cut-off scores for its use in medical wards. METHODS One hundred and fifty-five patients [53% female; mean age (+/- S.D.) = 49.5 (+/- 17) years; mean number of years of education (+/- S.D.) = 6 (+/- 4) years] consecutively admitted to the adult medical wards in a General Hospital were interviewed during the first 72 h of hospitalization. The Clinical Interview Schedule [CIS] was used to make ICD-10 psychiatric diagnoses. All patients completed the BDI-SF. A "receiver operating characteristics" (ROC) curve was obtained and the sensitivity, specificity, positive and negative predictive values were calculated for different cut-off points of the BDI-SF. RESULTS High sensitivity and negative predictive value (NPV) were obtained with a cut-off score of 9/10 (sensitivity = 100%, specificity = 83.1%, NPV = 100%). High sensitivity and positive predictive value (PPV) were obtained with a cut-off score of 13/14 (sensitivity = 93.5%, specificity = 96%, PPV = 85.3%). The area under the ROC curve was 98.4% (95% Confidence Interval = 0.97-1.00). CONCLUSIONS The BDI-SF is a valid instrument for detecting moderate and severe depression in medical inpatients. For screening purposes, a 9/10 cut-off score is indicated, but if a high specificity is desired, a 13/14 cut-off score is warranted.

Abstract
Obstructive Sleep Apnea Syndrome (OSAS) is a debilitating condition stemming from disruption to the respiratory system during sleep. At present, the nature of the relationship between OSAS and mood, specifically depression and anxiety, is still unclear. The purpose of this paper is to shed some light on this relationship. PsycINFO was used to locate relevant papers on this topic. This literature search formed the basis of our investigation. Results showed that the anxiety and depression methodology is weak. It is now clear that there is an urgent need to better understand the roles of anxiety and depression in OSAS. For example, the research literature suggests that depression and anxiety covary with OSAS. However, because of methodological issues, such as difficulties involved in diagnosis and the use of inappropriate instruments, this conclusion remains tenuous. Future directions are discussed.

Abstract
BACKGROUND AND PURPOSE To determine the frequency and severity of disorders of sleep and wake and their relation to the quality of life (QoL) in patients who have survived an episode of subarachnoid hemorrhage (SAH). METHODS In a prospectively collected, consecutive series of 89 patients, 83 patients completed validated and frequently used questionnaires for the assessment of disorders of sleep and wake (SDL and Epworth Sleepiness Score) at least 1 year (range, 1 to 3.4 years) after the SAH. We used the modified Rankin scale for functional outcome and Short Form 36 (SF-36) to assess QoL. We related the occurrence of severe problems with sleep (insomnia or excessive daytime sleepiness score or both > or =3 on SDL) to functional outcome and to the QoL scores and compared the latter scores with data from a Dutch reference population. In a subset of 20 patients with severe problems with sleep, we performed polysomnographic and actigraphic studies at home during 48 hours. RESULTS Twenty eight (34%) patients had severe problems with sleep. Frequently reported problems are initiating (25%) or maintaining (31%) sleep, difficulty returning (28%) asleep, tiredness (31%), and excessive sleepiness during the day (6%). QoL was considerably reduced in patients with severe problems with sleep. During the sleep monitoring studies, severe sleep fragmentation, sleep apnea, restless legs syndrome/periodic limb movement disorder, or a combination of these disorders of sleep and wake occurred in 19 of 20 patients. CONCLUSIONS Many patients who have survived an episode of SAH have disorders of sleep and wake, which are related to the QoL.

Abstract
OBJECTIVE To investigate the heterogeneity of idiopathic Parkinson's disease (PD) in a data driven manner among a cohort of patients in the early clinical stages of the disease meeting established diagnostic criteria. METHODS Data on demographic, motor, mood, and cognitive measures were collected from 120 consecutive patients in the early stages of PD (Hoehn and Yahr I-III) attending a specialist PD research clinic. Statistical cluster analysis of the data allowed the existence of the patient subgroups generated to be explored. RESULTS The analysis revealed four main subgroups: (a) patients with a younger disease onset; (b) a tremor dominant subgroup of patients; (c) a non-tremor dominant subgroup with significant levels of cognitive impairment and mild depression; and (d) a subgroup with rapid disease progression but no cognitive impairment. CONCLUSIONS This study complements and extends previous research by using a data driven approach to define the clinical heterogeneity of early PD. The approach adopted in this study for the identification of subgroups of patients within Parkinson's disease has important implications for generating testable hypotheses on defining the heterogeneity of this common condition and its aetiopathological basis and thus its treatment.

Abstract
OBJECTIVE To evaluate obesity as a marker for increased pain severity, disability, and psychologic distress in treatment-seeking, mixed chronic pain patients. METHODS Three hundred seventy-two consecutive chronic pain patients seeking evaluation at a university pain clinic were divided into 3 weight categories, based on body mass index (BMI): normal (BMI < 25 kg/m2), overweight (BMI between 25 kg/m and 30 kg/m2), and obese (BMI > or = 30 kg/m2). Patients completed questionnaires to identify pain severity, disability, depression, anxiety, and quality of life. RESULTS Pain severity and days per week with pain were similar among the weight groups. Disability was related to increasing weight status, with increased BMI associated with more days per week with both reduced activity and complete disability. Depressive symptoms were also related to weight category, with an average Beck Depression Inventory score of 11.81 +/- 7.55 in normal, 12.88 +/- 11.64 in overweight, and 15.78 +/- 9.88 in obese patients. Anxiety scores were similar among the weight categories. Physical function domain of quality of life was also reduced in relation to weight. CONCLUSIONS Weight is associated with co-morbid disability, depression, and reduced quality of life for physical function in chronic pain patients. Calculation of the BMI should become a routine part of the screening evaluation for chronic pain patients, with additional screening for disability and psychologic distress in patients with elevated BMIs.

Abstract
This prospective study aimed to assess the suitability of the 21-item Beck Depression Inventory (BDI-21) as a screening method for current episodes of major depressive disorder in different phases of the disease. In a sample of treatment-seeking outpatients (n=125), a structured interview method (SCID) was used twice with a 2-year interval to screen whether the patient had a current episode of major depressive disorder. The validity of the BDI-21 was also analysed by means of receiver operating characteristic (ROC) curves. The results showed that with a cut-off point of 14/15 the BDI-21 can be used to indicate the presence of a major depressive episode regardless of the phase of the major depressive disorder. The sensitivity and specificity were quite satisfactory with this cut-off point. The areas under the ROC curves were large (0.81 at baseline and 0.93 at follow-up). The same BDI-21 cut-off point is suitable for screening major depression among outpatients in any phase of the disease.

Abstract
We have used multiple sources to identify a population-representative cohort of newly diagnosed patients with parkinsonism and Parkinson's disease in the UK over a 2-year period. All patients have been invited to participate in a detailed clinical assessment either at home or in an outpatient clinic. These assessments have been used to refine clinical diagnoses of parkinsonism using established criteria, and describe some of the phenotypic variability of Parkinson's disease at the time of diagnosis. The crude incidence of Parkinson's disease was 13.6/10(5yr-1) [confidence interval (CI) 11.8-15.6 and of parkinsonism was 20.9/10(5yr-1) (CI 18.7-23.3). Age-standardized to the 1991 European population, the incidence figures become 10.8/10(5yr-1) (CI 9.4-12.4) for Parkinson's disease and 16.6/10(5yr-1) (CI 14.8-18.6) for parkinsonism. Thirty-six per cent of the Parkinson's disease patients had evidence of cognitive impairment based on their performance in the Mini-Mental State Examination, a pattern recognition task, and the Tower of London task. The pattern of cognitive deficits seen among these patients using these and further cognitive tasks suggests that sub-groups of patients based on cognitive ability might be identifiable even in the early stages of disease, which may reflect regional differences in the underlying neuropathological processes.

Abstract
BACKGROUND The aim of the current study was to assess the reliability, validity and the psychometric properties of the Greek translation of the Symptoms Rating Scale For Depression and Anxiety. The scale consists of 42 items and permits the calculation of the scores of the Beck Depression Inventory (BDI)-21, the BDI 13, the Melancholia Subscale, the Asthenia Subscale, the Anxiety Subscale and the Mania Subscale METHODS 29 depressed patients 30.48 +/- 9.83 years old, and 120 normal controls 27.45 +/- 10.85 years old entered the study. In 20 of them (8 patients and 12 controls) the instrument was re-applied 1-2 days later. Translation and Back Translation was made. Clinical Diagnosis was reached by consensus of two examiners with the use of the SCAN v.2.0 and the IPDE. CES-D and ZDRS were used for cross-validation purposes. The Statistical Analysis included ANOVA, the Spearman Correlation Coefficient, Principal Components Analysis and the calculation of Cronbach's alpha. RESULTS The optimal cut-off points were: BDI-21: 14/15, BDI-13: 7/8, Melancholia: 8/9, Asthenia: 9/10, Anxiety: 10/11. Chronbach's alpha ranged between 0.86 and 0.92 for individual scales. Only the Mania subscale had very low alpha (0.12). The test-retest reliability was excellent for all scales with Spearman's Rho between 0.79 and 0.91. CONCLUSIONS The Greek translation of the SRSDA and the scales that consist it are both reliable and valid and are suitable for clinical and research use with satisfactory properties. Their properties are close to those reported in the international literature. However one should always have in mind the limitations inherent in the use of self-report scales.

Abstract
Parkinson's disease is frequently associated with depressive symptoms. When depression occurs at early stages and before the onset of characteristic motor symptoms of the disease, differential diagnosis of major depression may be difficult. Differences in psychopathological features of depression in Parkinson's disease and major depression have been reported by some authors. This study presents data of 49 patients with depression in Parkinson's disease and 38 patients with major depression. The severity of depressive symptoms was equivalent in both groups. Depressive features did not differ between the two groups with exception of affective flattening, delusional ideas and suicide attempts. In conclusion, this investigation gives support to the assumption of a common neurobiological origin of depression in Parkinson's disease and major depression.

Abstract
Parkinson's disease (PD) is primarily a disease of elderly individuals with a peak age at onset of 55 to 66 years. It is characterized by bradykinesia, rigidity, tremor, and postural instability; and affects approximately 1 million individuals in the US and is the second most common neurodegenerative disease next to Alzheimer's disease. The motor symptoms of PD are the focus of pharmacotherapy, yet the nonmotor symptoms (e.g., dementia, psychosis, anxiety, insomnia, autonomic dysfunction, and mood disturbances) can be the most disturbing, disabling, and misunderstood aspects of the disease. Depressive symptoms occur in approximately half of PD patients and are a significant cause of functional impairment for PD patients. There is accumulating evidence suggesting that depression in PD is secondary to the underlying neuroanatomical degeneration, rather than simply a reaction to the psychosocial stress and disability. The incidence of depression is correlated with changes in central serotonergic function and neurodegeneration of specific cortical and subcortical pathways. Understanding comorbid depression in PD may therefore add to the understanding of the neuroanatomical basis of melancholia.

Abstract
An 8-month multicentre prospective randomized study aimed at comparing the effects of dopamine receptor agonists pramipexole (PPX; Mirapexin) and pergolide (PRG; Permax) as add-on to L-dopa therapy on depression [Montgomery and Asberg Depression Rating Scale (MADRS)] in 41 non-demented patients (25 men, 16 women) suffering from both mild or moderate depression and advanced Parkinson's disease (PD). The assessment was performed by a blinded independent observer. Motor symptoms (UPDRS III), motor complications (UPDRS IV), activities of daily living (UPDRS II and VI) and depressive symptoms as measured by Self - Rating Depression Scale by Zung were evaluated in an open-label design. The average value of Zung scores decreased significantly in both groups with no statistical difference between both groups. A significant decrease in the average value of MADRS scores was present only in the PPX group. The average UPDRS scores decreased significantly with no statistical difference between both groups at the comparable average total daily dose of both preparations. In both cases, the total daily dose of L-dopa decreased significantly but the decrease was statistically more pronounced in the PRG group. Our results demonstrate the antidepressant effect of PPX in patients with PD while we can't make any conclusions with regard to antidepressant effect of PRG.

Abstract
OBJECTIVES Studies on neuropsychological functions in early Parkinson's disease (PD) have reported changes with respect to memory and executive control related to dysfunction of fronto-striatal circuitry. The question has been raised, however, whether these findings are at least partly influenced by depression, which as such can also lead to cognitive impairments that depend on the functional integrity of the prefrontal cortex. MATERIAL AND METHODS In the present investigation early non-depressed PD patients (NPD), early PD patients with mild depressive symptoms (DPD), patients with primary depression (DEP) and healthy controls (HC) completed a range of neuropsychological tests. RESULTS Group comparisons revealed impairments of DPD patients in comparison with HC with respect to verbal fluency, short-term memory and concept formation. In addition they showed mild working-memory deficits. CONCLUSIONS In summary the present results indicate that depressed mood in early PD may exacerbate cognitive impairments. Thus careful assessment of affective variables in PD should be an integral part of the treatment of PD.

Abstract
OBJECTIVE To assess the psychometric properties of the Spanish version of the Hospital Anxiety and Depression Scale(HADS). METHOD We administered HADS to 685 participants (256 controls and 429 patients with five different diagnoses). The reliability of the instrument was assessed by a test-retest study. Construct validity studies were carried out through item-subscale correlation and factor analysis for the whole group and by each of the five different diagnoses. Three instruments were used as external criteria to assess concurrent validity. RESULTS HADS test-retest reliability presented correlation coefficients above 0.85. The internal consistency was high, with a Cronbach's alpha of 0.86 (anxiety) and 0.86 (depression). Factor analysis showed a clear two-factor structure for all groups. The results showed high concurrent validity with the Beck Depression Inventory and State-Trait Anxiety Inventory and with the mental domains of the Short-Form Health Survey. CONCLUSION The Spanish version of the HADS demonstrated good reliability and validity when used in medical patients.
