Abstract
ObjectiveA total of 48% of patients with Parkinson's disease (PD) present symptoms of gastrointestinal dysfunction, particularly constipation. Furthermore, gastrointestinal tract (GIT)-related non-motor symptoms (NMSs) appear at all stages of PD, can be prodromal by many years and have a relevant impact on the quality of life. There is a lack of GIT-focused validated tools specific to PD to assess their occurrence, progress, and response to treatment. The aim of this study was to develop and evaluate a novel, disease- and symptom-specific, self-completed questionnaire, titled Gut Dysmotility Questionnaire (GDQ), for screening and monitoring gastrointestinal dysmotility of the lower GIT in patients with PD.MethodsIn phase 1, a systematic literature review and multidisciplinary expert discussions were conducted. In phase 2, cognitive pretest studies comprising standard pretests, interviews, and evaluation questionnaires were performed in patients with PD (n = 21), age- and sex-matched healthy controls (HC) (n = 30), and neurologists (n = 11). Incorporating these results, a second round of cognitive pretests was performed investigating further patients with PD (n = 10), age- and sex-matched HC (n = 10), and neurologists (n = 5). The questionnaire was adapted resulting in the final GDQ, which underwent cross-cultural adaptation to the English language.ResultsWe report significantly higher GDQ total scores and higher scores in five out of eight domains indicating a higher prevalence of gastrointestinal dysmotility in patients with PD than in HC (p < 0.05). Cognitive pretesting improved the preliminary GDQ so that the final GDQ was rated as relevant (100/100%), comprehensive (100/90%), easy to understand concerning questions and answer options (100/90%), and of appropriate length (80/100%) by neurologists and patients with PD, respectively. The GDQ demonstrated excellent internal consistency (Cronbach‘s alpha value of 0.94). Evidence for good construct validity is given by moderate to high correlations of the GDQ total score and its domains by intercorrelations (rs = 0.67–0.91; p < 0.001) and with validated general NMS measures as well as with specific items that assess gastrointestinal symptoms.InterpretationThe GDQ is a novel, easy, and quick 18-item self-assessment questionnaire to screen for and monitor gastrointestinal dysmotility with a focus on constipation in patients with PD. It has shown high acceptance and efficacy as well as good construct validity in cognitive pretests.

Abstract
People with spinal cord injuries (SCI), and particularly with high level lesions, can potentially lose the ability to effectively operate computers. The Multimedia Authoring and Management using your Eyes and Mind (MAMEM) project aims to design and produce a novel assistive device to support computer use by individuals with SCI and other disabilities. The solution harnesses eye tracking and brain waves, as measured by encephalography (EEG), to manipulate common computer functions. This paper describes the first step in the project, during which we defined clinically related requirements of the assistive device. These definitions were based on data from three sources: (1) a narrative review; (2) a focus group of SCI rehabilitation professionals; and (3) structured questionnaires administrated to potential computer users with SCI, addressing computer-use habits, barriers, and needs. We describe both the collection of data from each source and the clinically related requirements extracted. The novel three-source requirement assessment method is discussed, and the advantages and disadvantages of each data source are reported. In conclusion, we suggest that this approach makes it possible to organize, discuss, and prioritize the requirements, and to create a work program while planning the device. This increases our level of certainty that the efficacy and adequacy of the assistive device will be maximized, in terms of the clinical needs of users.

Abstract
BACKGROUND In the literature, several reports are describing the coexistence of Huntington's disease (HD) or myasthenia gravis (MG) with other neurodegenerative and autoimmune disorders. Herein, we report a rare case of HD in a 66-year-old male with MG. Description of the case: The diagnosis of MG was established by acetylcholine receptor antibodies testing and compatible clinical presentation. The diagnosis of HD was based on clinical features, family history, and DNA testing. Several immunologic mechanisms have been proposed regarding the pathogenesis of HD and MG, respectively. Sharing a common autoimmune aspect could be an uncertain but potential association between the two disorders. CONCLUSION The probability of HD and MG occurring in the same patient is extremely small. While a number of neurological and autoimmune disorders have been reported with HD and MG, this is the first described coexistence of these two entities. HIPPOKRATIA 2019, 23(1): 28-29.

Abstract
Wide comprehension of genetic features of cerebral cavernous malformations (CCM) represents the starting point to better manage patients and risk rating in relatives. The causative mutations spectrum is constantly growing. KRIT1, CCM2, and PDCD10 are the three loci to date linked to familial CCM development, although germline mutations have also been detected in patients affected by sporadic forms. In this context, the main challenge is to draw up criteria to formulate genotype-phenotype correlations. Clearly, genetic factors determining incomplete penetrance of CCM need to be identified. Here, we report two novel intronic variants probably affecting splicing. Molecular screening of CCM genes was performed on DNA purified by peripheral blood. Coding exons and intron-exon boundaries were sequenced by the Sanger method. The first was detected in a sporadic patient and involves KRIT1. The second affects CCM2 and it is harbored by a woman with familial CCM. Interestingly, molecular analysis extended to both healthy and ill relatives allowed to estimate, for the first time, a penetrance for CCM2 lower than 100%, as to date reported. Moreover, heterogeneity of clinical manifestations among those affected carrying the same genotype further confirms involvement of modifier factors in CCM development.

Abstract
We present a dataset that combines multimodal biosignals and eye tracking information gathered under a human-computer interaction framework. The dataset was developed in the vein of the MAMEM project that aims to endow people with motor disabilities with the ability to edit and author multimedia content through mental commands and gaze activity. The dataset includes EEG, eye-tracking, and physiological (GSR and Heart rate) signals collected from 34 individuals (18 able-bodied and 16 motor-impaired). Data were collected during the interaction with specifically designed interface for web browsing and multimedia content manipulation and during imaginary movement tasks. The presented dataset will contribute towards the development and evaluation of modern human-computer interaction systems that would foster the integration of people with severe motor impairments back into society.

Abstract
BACKGROUND Previous transcranial magnetic stimulation (TMS) studies in patients with tropical spastic paraparesis (TSP) have focused on central motor conduction time measurements while other TMS parameters remained unexplored. From a neuroradiological point of view, pyramidal tract involvement with magnetic resonance imaging and diffusion tensor imaging (DTI) has been rarely reported in TSP. Accordingly, the present study investigated the mean threshold (MT) and silent period (SP) as well as DTI measurements in TSP. CASE DESCRIPTION A 35-year-old female patient presented with a 15-year history of spastic paraparesis with minimal upper-limb involvement. Serum and cerebrospinal fluid samples were positive for HTLV-I. TMS was performed with a figure-of-eight coil (recording, abductor hallucis and first dorsal interosseous muscles). Thr was measured at 1 % steps. SPs were elicited at 5 % increments from 0 to 100 % maximum stimulus intensity (SI), and data were used to construct a stimulus/response (S/R) curve of SI vs SP. The resulting S/R curves were fitted to a Boltzmann equation and statistically compared to control data. Voxel-based DTI analysis was performed with SPM 99. Corticospinal tractography was based on diffusion tensor data. The TMS examination disclosed that MT was significantly increased (54.5 ± 6.36 % vs 41.08 ± 7.85 % in a group of 82 controls, p=0.019). The patient's SP S/R curve had significantly reduced Max values compared to 13 age-matched controls (160.4 ± 0.91 ms vs 228.36 ± 38.69 ms, p <0.001). Fractional anisotropy was decreased in a cluster of voxels corresponding to the area of the pyramidal tract (0.388 ± 0.015 vs 0.506 ± 0.02 in 20 age-matched controls, p <0.001). CONCLUSION The described results provide novel neurophysiological and imaging evidence for central motor pathways malfunctioning in TSP. HIPPOKRATIA 2017, 21(4): 191-193.

Abstract
BACKGROUND/OBJECTIVE The aim of this study was to describe the rate and clinical predictors of cognitive decline in dementia with Lewy bodies (DLB), and compare the findings with Alzheimer's disease (AD) and Parkinson's disease dementia (PDD) patients. METHODS Longitudinal scores for the Mini-Mental State Examination (MMSE) in 1,290 patients (835 DLB, 198 PDD, and 257 AD) were available from 18 centers with up to three years longitudinal data. Linear mixed effects analyses with appropriate covariates were used to model MMSE decline over time. Several subgroup analyses were performed, defined by anti-dementia medication use, baseline MMSE score, and DLB core features. RESULTS The mean annual decline in MMSE score was 2.1 points in DLB, compared to 1.6 in AD (p = 0.07 compared to DLB) and 1.8 in PDD (p = 0.19). Rates of decline were significantly higher in DLB compared to AD and PDD when baseline MMSE score was included as a covariate, and when only those DLB patients with an abnormal dopamine transporter SPECT scan were included. Decline was not predicted by sex, baseline MMSE score, or presence of specific DLB core features. CONCLUSIONS The average annual decline in MMSE score in DLB is approximately two points. Although in the overall analyses there were no differences in the rate of decline between the three neurodegenerative disorders, there were indications of a more rapid decline in DLB than in AD and PDD. Further studies are needed to understand the predictors and mechanisms of cognitive decline in DLB.

Abstract
Canavan's disease (CD) is a hereditary leukodystrophy caused by mutations in the aspartoacylase gene (ASPA), leading to spongiform degeneration of the white matter and severe impairment of psychomotor development. We present the cases of two non-Jewish sisters with CD that have a milder and protracted clinical course compared to typical CD. MRI imaging revealed bilateral high-signal-intensity areas in the thalami and the internal capsule and MR spectroscopy showed typical findings for CD (a marked increase in N-acetylaspartate (NAA) levels). FA values of the right and left corticospinal tracts at the level of the posterior limb of the internal capsule, and the centrum semiovale were found to be significantly reduced compared to healthy controls. From a neurophysiological point of view, the peripheral motor system was normal. In contrast, cortical stimulation at maximal intensity failed to elicit facilitated or resting MEPs and silent periods (SPs) in upper and lower limbs, providing evidence for significant upper motor pathway dysfunction.

Abstract
Almost two decades of genetic research in Parkinson's disease (PD) have remarkably increased our knowledge regarding the genetic basis of PD with numerous genes and genetic loci having been found to cause familial PD or affect the risk for PD. Approximately 5-10% of PD patients have monogenic forms of the disease, exhibiting a classical Mendelian type of inheritance, however, the majority PD cases are sporadic, probably caused by a combination of genetic and environmental risk factors. Nowadays, six genes, alpha synuclein, LRRK2, VPS35, Parkin, PINK1 and DJ-1, have definitely been associated with an autosomal dominant or recessive PD mode of inheritance. The advent of genome-wide association studies (GWAS) and the implementation of new technologies, like next generation sequencing (NGS) and exome sequencing has undoubtedly greatly aided the identification on novel risk variants for sporadic PD. In this review, we will summarize the current progress and future prospects in the field of PD genetics.

Abstract
Auditory event-related potentials were evaluated in 45 nondemented patients with mild to moderate Parkinson's disease and 40 matched normal controls. All patients were neuropsychologically assessed by means of the Raven Colored Progressive Matrices, four subtests of the Wechsler Memory Scale (Digit Span Forward, Logical Memory, Visual Memory, Associate Learning), and the Wisconsin Card-sorting Test. The P300 component of the auditory event-related potentials was significantly prolonged in the patients with Parkinson's disease. Correlations between P300 latency and neuropsychological measures showed significant associations with lower performance on the Raven Colored Progressive Matrices and the Wisconsin Card-sorting Test. Our results indicate that for patients with mild to moderate Parkinson's disease subtle changes in cognitive abilities may be reflected as P300 prolongation.

Abstract
BACKGROUND AND AIM Autonomic symptoms in Parkinson's disease (PD) are very common and contribute to the severity of patient's disability. We evaluated the occurrence of autonomic symptoms in Greek patients with PD utilizing the Scales for Outcomes in Parkinson's Disease-Autonomic questionnaire (SCOPA-AUT), a specific 23-item self-completed questionnaire for the assessment of autonomic dysfunction in patients with PD. SUBJECTS AND METHODS One hundred and sixty-one PD patients and forty matched controls were enrolled in the study. Clinical assessment was performed with the Hoehn and Yahr scale. Patients completed a demographic questionnaire, the Non-Motor Symptoms Questionnaire (NMSQuest), the Parkinson's Disease Questionnaire (PDQ-39) and the SCOPA-AUT scale which was properly translated into Greek and validated for the study. RESULTS SCOPA-AUT scale showed a good reliability profile and correlated well with other measures for non-motor symptoms and health-related quality measures in PD patients. PD patients scored higher than controls in the total SCOPA -AUT score (mean score 11.9 versus 6.4). Patients reported problems in many items of the SCOPA-AUT, but the most common autonomic symptoms emerged in the Urinary and the Gastrointestinal domains. Especially sialorrhea, constipation, straining for defecation, incontinence and nocturia differentiated patients from controls. Furthermore, mean total SCOPA-AUT score correlated with duration and severity of the disease. CONCLUSION Autonomic symptoms in PD are too important to remain undetected. By incorporating into everyday practice the use of suitable and reliable questionnaires, physicians will be able to adequately detect and manage these symptoms. Hippokratia 2016, 20(2):115-120.

Abstract
BACKGROUND G209A SNCA mutation carriers represent an important group of genetic PD. We describe motor and nonmotor features of G209A SNCA mutation carriers. METHODS Longitudinal clinical assessments over 2 years were collected in 22 symptomatic and 8 asymptomatic G209A SNCA mutation carriers. Motor and nonmotor rating scales were administered. Correlations were performed between clinical variables and disease duration or age. Penetrance was calculated using Kaplan-Meier survival curves. RESULTS Asymptomatic carriers did not manifest clear premotor symptoms, but symptomatic carriers often reported that olfactory dysfunction and rapid eye movement sleep behavior disorder preceded motor symptoms. Prominent motor decline and deterioration of autonomic and cognitive function occurred at follow-up; such nonmotor features correlated with disease duration, but not age. Disease penetrance was estimated at around 90%. CONCLUSIONS This study may help to inform clinical trials and provide the basis for studies of disease modifiers in genetic synucleinopathy cohorts. © 2016 International Parkinson and Movement Disorder Society.

Abstract
Parkinson's disease is a neurodegenerative disease, with a constantly increasing prevalence and a high global financial impact arising from direct and indirect costs. Large-scale, observational studies provide data that support the better comprehension of disease aspects, constitute a baseline reference for future studies and assist comparisons among different patient populations, allowing the recognition of distinctive characteristics and special needs. The present study is the first to depict the clinical characteristics and their interplay in a large sample of Parkinson's disease (PD) patients in Greece. Nine hundred eighty six consecutive PD outpatients were recruited from 17 centers around Greece in the time period from 8/2007 to 7/2009 and were examined and interviewed by movement disorders experts. Multiple clinical characteristics were recorded including age at diagnosis, disease severity, patients' self classification of PD symptoms and their relevance to physician's global clinical impression, smoking, alcohol consumption, presence of family history for PD, dementia, depression, hypertension, cancer and other comorbidities. Associations of high clinical significance were found between certain clinical characteristics.

Abstract
OBJECTIVES To compare the dopaminergic neuronal imaging features of different subtypes of genetic Parkinson's Disease. METHODS A retrospective study of genetic Parkinson's diseases cases in which DaTSCAN (123I-FP-CIT) had been performed. Specific non-displaceable binding was calculated for bilateral caudate and putamen for each case. The right:left asymmetry index and striatal asymmetry index was calculated. RESULTS Scans were available from 37 cases of monogenetic Parkinson's disease (7 glucocerebrosidase (GBA) mutations, 8 alpha-synuclein, 3 LRRK2, 7 PINK1, 12 Parkin). The asymmetry of radioligand uptake for Parkinson's disease with GBA or LRRK2 mutations was greater than that for Parkinson's disease with alpha synuclein, PINK1 or Parkin mutations. CONCLUSIONS The asymmetry of radioligand uptake in Parkinsons disease associated with GBA or LRRK2 mutations suggests that interactions with additional genetic or environmental factors may be associated with dopaminergic neuronal loss.

Abstract
BACKGROUND AND AIM Νon-motor symptoms in Parkinson's disease (PD) are very common and contribute to the severity of patient's disability. We evaluated the frequency of nonmotor symptoms in patients with PD and we explored the influence of disease characteristics on the presence of these symptoms. PATIENTS AND METHODS One hundred sixty six patients and sixty six matched controls were enrolled in the study. The Non-Motor Symptoms Questionnaire (NMSQuest), a 30-item self-completed questionnaire, was used for the evaluation of nonmotor symptoms. RESULTS Non-motor symptoms were more common in PD patients than controls. Mean ± SD NMSQuest score was 6.76 ± 4.22 in PD patients and 5.44 ± 4.45 in controls (p=0.035). The more common non-motor symptoms in PD patients were urinary urgency (54.3%), nocturia (51.8%), constipation (45.7%) and sadness (42.1%). There was a correlation between NMSQuest score and severity of the disease. CONCLUSION Non-motor symptoms in PD are too important to remain undetected. By incorporating into every day practice the use of suitable, reliable questionnaires, we will be able to facilitate detection and management of these symptoms.

Abstract
In a recent web based genome-wide association study (GWA) the rs6812193 polymorphism was identified as a new risk factor for Parkinson's disease (PD). The purpose of our study was to examine the association of the rs6812193 polymorphism with Parkinson's disease (PD) in case-control association study of Greek individuals. We studied a total of 343 individuals, 210 Greek patients with sporadic PD and 133 control subjects, using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. We found no differences in genotype or allele frequencies between PD patients and controls (P=0.795 and P=0.892, respectively), suggesting that the rs6812193 polymorphism does not increase susceptibility to PD in the Greek population. Additional studies further investigating the association of the rs6812193 polymorphism with PD are needed in order to clarify the role of this polymorphism in different ethnicities.

Abstract
Parkinson 's disease (PD) is characterized by progressive loss of dopaminergic neurons in the nigrostriatal pathway, but this seems to constitute only part of the whole pathological process of the disease. Accumulating data have documented the concomitant degeneration of other dopaminergic pathways and of the serotonergic, cholinergic and noradrenergic neurotransmitter systems. In addition, pathologic process is not only restricted in the brain, since the spinal cord and the peripheral autonomic nervous system are also affected. The pathogenesis of PD remains unclear. The use of positron emission tomography and single photon emission tomography may contribute to the understanding of these aspects of the disease. This review will discuss the role of PET and SPET in imaging the extrastriatal dopaminergic system and other neurotransmitter systems as well as the imaging of microglial activation and cardiac sympathetic denervation in PD. In conclusion, several PET and SPET ligands can detect changes in extrastriatal dopaminergic system as well as in the serotonergic, cholinergic and noradrenergic systems in PD and also explore its possible correlation with motor and non motor symptoms. The use of PET scintigraphy allows the detection of microglial activation in PD, while (123)I-MIBG scintigraphy depicts cardiac sympathetic denervation in PD and is a useful imaging tool for differentiating PD from other types of parkinsonism.

Abstract
Mechanisms that mediate inflammatory responses may be crucial in Parkinson's disease (PD) pathogenesis. In the brain, the chemokine receptor CX3CR1 is exclusively expressed in microglia, selectively mediating microglia-neuron interaction in response to its ligand, the chemokine fractalkine. Two functional single nucleotide polymorphisms, V249I and T280M, in the coding sequence of the CX3CR1 receptor have been found to alter ligand-receptor affinity. The aim of this study was to investigate the genetic role of CX3CR1 in sporadic PD. We examined the V249I and T280M CX3CR1 polymorphisms in a case-control study of 176 sporadic PD patients and 115 controls. Polymerase chain reaction-restriction fragment length polymorphism analysis was performed for the detection of the studied CX3CR1 genotypes. This is the first study that tests CX3CR1 gene polymorphisms in patients with PD. We found no differences in genotype or haplotype frequencies between PD patients and controls, suggesting that CX3CR1 V249I and T280M polymorphisms do not increase susceptibility to PD. Additional studies should further investigate the CX3CL1-CX3CR1 axis in PD.

Abstract
Parkinson disease (PD) is a progressive movement disorder marked by tremor, rigidity, bradykinesia and postural instability. Levodopa (l-dopa), usually combined with a peripheral dopa decarboxylase inhibitor, has been proved to provide the best symptomatic benefit for PD. However, its long-term efficacy is limited because of motor complications and drug-induced dyskinesia. Dopamine agonists, catechol-O-methyltransferase inhibitors and monoamine oxidase-B inhibitors are anti-parkinsonian (anti-PD) drugs that have been found to further improve the potency of l-dopa and prevent the onset of motor complications. However, as PD is a progressive disorder, all the drugs used for its therapy, manifest reduced efficacy and adverse effects with time. Research on the field of pharmacogenetics has pointed out that the genetic variability of each individual determines to a large extent the inter-individual variability in response to anti-PD drugs. Clinicogenetic trials show that drug efficacy or toxicity or susceptibility to side effects are features governed by genetic principles. This article is a review of the present pharmacological treatment of PD and current pharmacogenetic data for PD.

Abstract
The purpose of this study was the evaluation of pupil light reflex (PLR) in patients with Parkinson's disease (PD) by using a modern pupillometry system and the investigation of its potential relationship with dopamine transporter imaging (DaTSCAN), which is an objective method for the evaluation of presynaptic dopaminergic system. PLR was evaluated using pupillometry in 35 patients with PD without clinical evidence of autonomic dysfunction and 44 healthy matched controls. PLR was elicited using a fully automated pupillometry system and six parameters were measured. Dopamine transporter imaging was performed using radioactive ioflupane (123)I-FP-CIT [(123)I-N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)-nortropane]. A significant increase in latency and a significant decrease in amplitude, maximum constriction velocity, as well as maximum acceleration were observed in PD patients. There was no significant difference in initial radius and minimum radius values. Investigating the relationship between pupillometry parameters and (123)I-FP-CIT binding values, we correlated values from the semiquantitative analysis of radioligand uptake with pupillometry parameters, but we found no significant correlation. This study demonstrates PLR impairment in patients with PD without overt autonomic dysfunction. This impairment does not seem to correspond to the reduction of radioligand binding in the striatum as the result of presynaptic dopaminergic dysfunction, suggesting a different deterioration rate of these systems.

Abstract
To determine whether polymorphisms in the microtubule-associated protein tau (MAPT) and/or glycogen synthase kinase-3β (GSK3β) genes underpin susceptibility to Parkinson's disease (PD), we conducted a case-control association study in a Greek cohort of 196 PD cases and 163 healthy controls. In our study, the MAPT H1 haplotype was found to be significantly associated with PD, no association was detected between the intronic rs6438552 (-157 T/C) GSK3β polymorphism and PD, whereas the C/C genotype of the promoter rs334558 (-50 T/C) GSK3β polymorphism was found to exert a protective role. The C/C genotype of the rs334558 GSK3β polymorphism was also found to have an additional protective role in our MAPT H1/H1 PD subgroup. Haplotype analysis revealed that, the T-T haplotype of both GSK3β polymorphisms was over-represented in PD patients compared to controls, and this association was independent of MAPT H1 haplotype.

Abstract
Subdural hematoma is a rare cause of secondary parkinsonism. We report a 65-year-old woman with reversible parkinsonism due to bilateral chronic subdural hematomas. Symmetrical parkinsonism evolved acutely 45 days after a trivial head injury. Mild pyramidal signs were also present on her left side. MRI revealed bilateral chronic subdural hematomas. The patient's parkinsonism was completely abolished one month after successful neurosurgical evacuation of the hematomas.

Abstract
In this review article the significance of molecular imaging techniques, single photon emission tomography and positron emission tomography (SPET and PET), in the diagnosis and differential diagnosis of various types of dementia is described. A major part of this article is focused on molecular imaging in Alzheimer's disease where parietal, temporal and posterior cingulate cortex hypoperfusion and hypometabolism are the predominant findings in molecular imaging modalities. In cases of mild amnestic cognitive impairment, molecular SPET imaging can differentiate patients converting to Alzheimer's disease from non converters. Molecular SPET imaging with pre-synaptic dopamine receptors radioligand ((123)I-ioflupane or DaTSCAN), is the method of choice in order to differentiate Alzheimer's disease from Lewy body dementia. Finally, nuclear medicine procedures support the diagnosis in fronto-temporal and multi-infarct dementia.

Abstract
In the study described here we attempted to evaluate the personality profiles of 25 patients with juvenile myoclonic epilepsy (JME) at the time of diagnosis, before treatment, and to explore a potential relationship between behavioral aspects and clinical outcome. For this purpose we employed a standardized and objective instrument, the Minnesota Multiphasic Personality Inventory (MMPI), and found that patients with JME have a personality profile similar to that of the control group, which corresponds to the 3,1 code type MMPI profile. We also noted that the characteristics of this personality type include those described in patients with long-duration JME by previous researchers. Consequently, we conclude that personality aberrations are not a feature of this syndrome. Furthermore, we observed that under treatment, EEGs normalized in patients who had exhibited "psychotic tendencies" pretreatment. The credibility of our results is supported by the fact that assessment of the personality profile was not confounded by medication or the longitudinal burden of epileptic seizures.

Abstract
Autosomal dominant familial Parkinson's disease (PD) due to the alpha-synuclein (G209A) mutation shares similar clinical characteristics with sporadic PD. Pathological studies however indicate more widespread neuronal degeneration in the familial form. We performed (123)I-FP-CIT SPET (DaTSCAN) study in nine patients with familial PD carrying the alpha-synuclein (G209A) mutation and fifteen matched patients with sporadic disease. Both groups had equal radioligand reduction uptake in the striatum but the alpha-synuclein patients showed less asymmetry and increased putamen to caudate ratio. Our findings indicate that there are minor differences in DAT SPET parameters between alpha-synuclein and sporadic PD patients insufficient to provide differential diagnosis.

Abstract
OBJECTIVES To determine the frequency, distribution, and clinical features of Parkinson disease (PD) with PINK1 mutations. DESIGN Retrospective clinical and genetic review. SETTING University hospital. PATIENTS We performed extensive mutation analyses of PINK1 in 414 PD patients negative for parkin mutations (mean [SD] age at onset, 42.8 [14.3] years), including 391 unrelated patients (190 patients with sporadic PD and 201 probands of patients with familial PD) from 13 countries. RESULTS We found 10 patients with PD from 9 families with PINK1 mutations and identified 7 novel mutations (2 homozygous mutations [p.D297MfsX22 and p.W437R] and 5 single heterozygous mutations [p.A78V, p.P196QfsX25, p.M342V, p.W437R, and p.N542S]). No compound heterozygous mutations were found. The frequency of homozygous mutations was 4.26% (2 of 47) in families with autosomal recessive PD and 0.53% (1 of 190) in patients with sporadic PD. The frequency of heterozygous mutations was 1.89% (2 of 106) in families with potential autosomal dominant PD and 1.05% (2 of 190) in patients with sporadic PD. The mean (SD) age at onset in patients with single heterozygous mutations (53.6 [11.1] years; range, 39-69 years) was higher than that in patients with homozygous mutations (34.0 [20.3] years; range, 10-55 years). Myocardial iodine-123 metaiodobenzylguanidine uptake was low in patients with heterozygous mutations but not in those with homozygous mutations. CONCLUSIONS Our results suggest that homozygous PINK1 mutations tend to be diagnosed as the early-onset autosomal recessive form of PD. Single heterozygous mutations may contribute to the development of sporadic PD and also could be an additional genetic predisposition for developing familial PD. The reduced myocardial iodine-123 metaiodobenzylguanidine uptake observed in patients with single heterozygous PINK1 mutations is similar to that seen in patients with sporadic PD.

Abstract
INTRODUCTION Fatigue is a frequent symptom in Parkinson disease (PD), but its pathogenesis remains obscure. Fatigue may be influenced by depression and motor disability, but immunological factors have been also implicated. The purpose of the study was to assess fatigue in PD patients in relation to depression and various immunological factors. SUBJECTS AND METHODS Forty PD patients and 26 normal matched controls were studied. Fatigue was assessed by the Fatigue Severity Scale (FSS). The Beck Depression Inventory (BDI) was employed for depression screening. The following immunological factors were estimated: a) T- and B-lymphocytes, T-lymphocyte subsets (helper/suppressor cells) as well as natural killer cells (NK); b) circulating levels of interleukins IL-1alpha, IL-1beta, IL-6, IL-1 receptor antagonist (IL-1Ra) and tumor necrosis factor-alpha. RESULTS FSS mean score was higher in PD patients compared to controls (p < 0.01). Significant differences between patients and controls were found in the following immunological parameters. In PD patients: a) mean percentage of NK cells was higher, p < 0.01); b) IL-1beta levels were significantly increased (p < 0.01) and IL-1Ra levels were decreased (p < 0.001). FSS correlated significantly to BDI (p < 0.008). Circulating Il-1Ra levels correlated to fatigue severity (p < 0.01), but after exclusion of depressed PD subjects this correlation significance level dropped to p = 0.055. CONCLUSIONS Our results indicate that fatigue is a common non motor symptom in PD. Immunological differences between PD patients and controls were observed in percentages of NK cells, IL-1beta and IL-1Ra blood levels. Fatigue correlated to depression and IL-Ra levels. However after exclusion of depressed subjects IL-1Ra levels showed only a tendency to significance, leaving depression as the principle correlate of fatigue.

Abstract
Parkinson's disease (PD) is the second most common neurodegenerative disorder affecting approximately 2% of the population >60 years of age. Although, the etiology of PD is still unknown, the genetic background of the disease has been documented. Recently, a mutation in the LRRK2 gene, G2019S, was associated with 3-41% and 1-2% of familial and sporadic PD, respectively suggesting a pivotal role of LRRK2 in PD. In this report, we examine the association of the G2019S mutation with sporadic late-onset PD, in an independent cohort of Greek patients and controls.

Abstract
We compared the distribution of the Tau H1 haplotype and related subhaplotypes in a group of clinically diagnosed Parkinson's disease patients (n = 133) and in control individuals (n = 113) from northern Greece. We were able to detect a statistically significant overrepresentation of the H1H1 genotype in our patient group (OR for H1H1 vs. H1H2 and H2H2: 1.73; 95% CI: 1.03-2.90; P = 0.037). The H1 subhaplotype significantly associated with the disease in our population was different from the one previously reported for a Norwegian population, suggesting that the nature of the association of Tau with Parkinson's disease is influenced by ethnic variation.

Abstract
We describe a case with left hemiparkinsonism due to a parasagittal meningioma with surrounding edema compressing the right basal ganglia. The patient was successfully operated and his symptoms resolved completely. However 7 years later his hemiparkinsonism reappeared due to a relapse of the right parasagittal meningioma. This rare case points to the significance of neuroimaging in the evaluation of parkinsonism.

Abstract
Superficial siderosis (SS) is a rare entity. A chronic subarachnoid hemorrhage (SAH) leads to the deposition of ferric pigments and ions in the surface of the central nervous system (CNS). The cause of this hemorrhage is identified in half of the cases. The disease progresses slowly and the damage is often irreversible by the time diagnosis is established. The management focuses on the identification and ablation of the bleeding source. Knowledge about this entity is based on sporadic reports. We describe three cases of superficial siderosis and briefly review the literature.

Abstract
Hyperhomocysteinemia is considered a risk factor for vascular disease causing endothelial damage and consequently atherogenesis. The purpose of this study was to investigate the effect of elevated homocysteine on certain biochemical markers of endothelial function in patients with idiopathic Parkinson's disease (PD). Blood homocysteine levels were assessed in 57 PD patients and 40 matched normal controls. Investigation of the C677T 5,10 methylenetetrahydrofolate reductase (MTHFR) genotype was also performed in 43 PD patients. The following markers of endothelial function were assessed: superoxide dismutase (SOD), nitric oxide (NO), sICAM-1 and sE-selectin. Homocysteine levels were found mildly elevated in PD patients particularly in those treated with L-Dopa. MTHFR genotype did not influence significantly this finding. SOD activity was found reduced but it was not correlated to homocysteine levels. All other parameters measured were normal and were not related to hyperhomocysteinemia. Our findings indicate that mild hyperhomocysteinemia in PD patients was not associated with endothelial dysfunction.
