- L-DOPA-induced dyskinesia (LID) is a major complication of the pharmacotherapy of Parkinson's disease (PD). Animal models of LID are essential for investigating pathogenic pathways and therapeutic targets. While non-human primates have been the preferred species for pathophysiological studies, mouse models of LID have been recently produced and characterized to facilitate molecular investigations. Most of these studies have used mice with unilateral 6-hydroxydopamine (6-OHDA) lesions of the nigrostriatal projection sustaining treatment with L-DOPA for 1-4 weeks. Mice with complete medial forebrain bundle lesions have been found to develop dyskinetic movements of maximal severity associated with a pronounced post-synaptic supersensitivity of D1-receptor dependent signaling pathways throughout the striatum. In contrast, mice with striatal 6-OHDA lesions have been found to exhibit a variable susceptibility to LID and a regionally restricted post-synaptic supersensitivity. Genetic mouse models of PD have just started to be used for studies of LID, providing an opportunity to dissect the impact of genetic factors on the maladaptive neuroplasticity that drives the development of treatment-induced involuntary movements in PD.

Nursing and multidisciplinary interventions for Parkinson's disease : what is the evidence?
- 2007

- This paper reports the interim results of an ongoing systematic review of the available evidence for the effectiveness of nursing care for people with Parkinson's disease (PD). Five clinical and four health-economic evaluations suggest that the clinical and cost effectiveness of nursing care for PD remain inconclusive. This is in contrast to clinical experience and may be due to issues related to study designs, study interventions, and the outcome measures used. More studies are needed and may benefit from considering specific interventions evaluated using outcome measures that are valid and responsive representations of their expected outcomes.

Staged pathology in Parkinson's disease
- 2014

- There has been a tremendous development since a regional progression of pathology in subjects with Lewy bodies (LB) was initially proposed 30 years ago. The entity of dementia with Lewy bodies has been acknowledged, the main protein constituent of LBs--aggregated α-synuclein (αS)--has been identified and a stepwise progression of the pathology has been reported. Implementation of the staging strategies published provides a common ground for handling a case with a suspected α-synucleinopathy. It is always important to state the staging strategy implemented while assessing a case, as the strategy applied might influence both the reported stage of LB pathology and, ultimately, the final diagnosis of the patient.

Gender distribution in surgery for Parkinson's disease.

- 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.

Deep brain stimulation : new techniques

- The technology of the hardware used in deep brain stimulation (DBS), and the mode of delivering the stimulation have not significantly evolved since the start of the modern era of DBS 25 years ago.However, new technology is now being developed along several avenues. New features of the implantable pulse generator (IPG) allow fractionation of the electric current into variable proportions between different contacts of the multi-polar lead. Another design consists in leads that allow selective current steering from directionally placed electrode contacts that would deliver the stimulation in a specific direction or even create a directional shaped electric field that would conform to the anatomy of the brain target aimed at, avoiding adjacent structures, and thus avoiding side effects.Closed loop adaptive stimulation technologies are being developed, allowing a tracking of the pathological local field potential of the brain target, and delivering automatically the stimulation to suppress the pathological activity as soon as it is detected and for as long as needed. This feature may contribute to a DBS therapy "on demand", instead of continuously.Finally, advances in imaging technology are providing "new" brain targets, and increasingly allowing DBS to be performed accurately while avoiding the risks of microelectrode recording.
