- Cerebrospinal fluid (CSF) total α-synuclein is considered a potential biomarker for Parkinson's disease (PD), but little is known about the evolution of this marker during the course of the disease. Our objective was to investigate whether CSF total α-synuclein concentrations change over time and are associated with motor and cognitive function in PD.CSF total α-synuclein concentrations were quantified in 56 longitudinally followed PD patients, 27 of whom provided CSF repeatedly 2 and/or 4 years later. Another 18 subjects were included as controls. The samples were analyzed using two independent, validated ELISA methods: our recently developed and validated in-house ELISA and a commercial kit from BioLegend.CSF total α-synuclein levels did not distinguish PD patients from controls, displayed no substantial changes during a period of up to 4 years, and did not predict subsequent motor or cognitive decline. These findings were consistent for both analytical methods.Our findings do not support the clinical utility of total α-synuclein as a single diagnostic or prognostic biomarker in PD.

- Introduction: It has been suggested that depression in Parkinson's Disease (PD) is often unrecognized and undertreated. However, few previous studies have studied the use of antidepressants in a large sample of both home-dwelling and institutionalized elderly persons with PD. We aimed to study the use of antidepressants in older persons using anti-parkinson drugs (APD, used as a proxy for PD), stratified by residential setting. Methods: We analyzed individual data on age, sex, residential setting and drug use in over 1.5 million older persons in the Swedish Prescribed Drug Register on 31th of December 2013. Results: Twenty-two percent of the home-dwellers and 50% of the institutionalized elderly persons with APD used antidepressants. Persons with APD had a higher probability of use of any antidepressant compared to persons without APD. A selective serotonin reuptake inhibitor (SSRI) was the most commonly used antidepressants in both settings followed by mirtazapin. Conclusions: The high use of antidepressants among older persons with APD warrants further studies on the quality of treatment of depression in PD.

- The present study assessed the linguistic and content validity of the Swedish version of the 39-item Parkinson's disease questionnaire (PDQ-39). The frame question, response alternatives and two of the 39 items yielded substantial linguistic and stylistic problems. Such shortcomings would be expected to influence responses to, and the quality of, the whole questionnaire. Data support content validity of the PDQ-39 as a functional health status questionnaire, although some shortcomings were identified. This preliminary study illustrates the need for documented linguistic validity before new language adaptations of patient-reported outcome measures can be considered suitable for use in clinical trials, research, and practice.

- Parkinson's disease (PD) affects both women and men. The surgical treatment of this disease has experienced a worldwide increase since the mid-eighties. In order to document eventual differences in gender distribution of patients undergoing various stereotactic surgical procedures for PD, we reviewed scientific papers published during the last 14years.A literature search provided 145 clinical papers, published between January 1985 and February 1999, and dealing with pallidotomy, thalamotomy and deep brain stimulation procedures. These papers were scrutinised with respect to redundancies or other overlap of reported patients. The resulting numbers of patients were compiled according to gender, to surgical procedure, and to geographic area of origin of the publishing centers.In one third of the reviewed publications the gender of the patients was not specified. In the remaining papers, the overall sex distribution of patients who underwent surgery was 35% females and 65% males. These proportions between sexes were relatively consistent regardless of surgical procedure, and regardless of geographic origin of the publications.Male preponderance in patients undergoing surgery for PD cannot be explained by a corresponding difference in gender-prevalence of the disease. The criteria of selection, and patterns of referral, of patients for surgery, as well as the respective attitude of female and male patients toward surgery, may account for the uneven gender distribution in surgical PD patients.

- Purpose: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been the mainstream surgical procedure for advanced Parkinson’s disease (PD) during the last decade. Reports from a few individual centres have hinted that women who receive STN DBS are under-represented. We aimed to evaluate the gender distribution of patients with PD who had received STN DBS during the last ten years, and to discuss the findings in relation to studies on gender prevalence of PD.Methods: A search of the PubMed database of clinical papers in English language related to STN DBS between 2000 and 2009 was conducted. Care was taken to minimize redundancies in reporting of published patients. The proportion of men and women were expressed in total and according to pre-defined geographic regions.Results: One hundred and thirty five papers were eligible for review. The gender of the patients was specified in 119 papers on a total of 3880 patients, of which 63% were men. According to geographic origin of publications, the percentage of men with STN DBS was 68% in North America, 62% in Europe, 69% in Australia and 50% in Asia.Conclusions: The proportion of male patients who undergo STN DBS seems to exceed the reported male/female ratio of patients with PD.

- Background: Stereotactic functional neurosurgery on basal ganglia has a long history and the pioneers are mostly men. We aimed at finding out if there were women who have contributed pioneering work in this field. Methods: The literature was searched to identify women who have been first to publish innovative papers related to human basal ganglia surgery. Results: Six women fulfilling our criteria were found: Marion Smith, a British neuropathologist, made unique observations on stereotactic lesions of basal ganglia and thalamus on autopsied brains, and the lesions' relation to the reported clinical outcome. Natalia Bechtereva, a Russian neurophysiologist, pioneered the technique of therapeutic chronic deep brain stimulation to treat various brain disorders, including Parkinson's disease (PD). Denise Albe-Fessard, a French neurophysiologist, pioneered the technique of microelectrode recording (MER) in stereotactic functional neurosurgery. Gunvor Kullberg, a Swedish neurosurgeon, contributed in early CT imaging as well as early functional imaging of stereotactic lesions in PD and psychiatric patients. Hilda Molina, a Cuban neurosurgeon, established the Centro Internacional de Restauracion Neurologica (CIREN) and pioneered there MER-guided transplant surgery in PD patients. Veerle Vandewalle, a Belgian neurosurgeon, pioneered in 1999 deep brain stimulation (DBS) for Tourette Syndrome. Conclusion: Although men constitute the great majority of neurosurgeons, neurologists and other neuro-specialists who have made groundbreaking contributions in basal ganglia surgery, there are women who have made equally important and unique contributions to the field. The principal two techniques used today in functional stereotactic neurosurgery, MER and DBS, have once upon a time been pioneered by women. (C) 2013 Elsevier Ltd. All rights reserved.
