Abstract

Different gastrointestinal symptoms, such as excessive salivation, deterioration and other disorders affecting the teeth, dysphagia, gastroparesis, gastroesophageal reflux, constipation, difficult defecation or loss of weight are frequent events in all the stages of the development of Parkinson's disease and affect at least a third of the patients. These symptoms reflect the dysfunction of the enteric nervous system, and the stomach is one of the organs where alpha-synuclein is first deposited. Other factors, such as the dysfunction of structures in the central nervous system like the dorsal motor nucleus of the vagal nerve, hormonal factors or secondary effects deriving from the consumption of antiparkinsonian drugs, are involved in its origin. The present article offers a detailed review of the epidemiological, pathophysiological, clinical and therapeutic management aspects of the different gastrointestinal symptoms in Parkinson's disease.

Abstract

Continuous infusion of intraduodenal levodopa/carbidopa is an effective treatment that improves the motor complications and the quality of life of patients in the advanced stages of Parkinson's disease. However, it is not free of complications. These may present in the post-operative period following surgery (gastrostomy) or in the long-term during the follow-up period and can be related with the medication (levodopa/carbidopa), the stoma, the gastrostomy or the device (pump, enteral tube, parts of the FREKA system). The aim of this review is to report on the management of the complications that can be observed in patients with advanced Parkinson's disease treated with continuous infusion of intraduodenal levodopa/carbidopa.

Abstract

Functional connectivity was evaluated in patients with schizophrenia (SC) and in patients with Parkinson's disease (PD) during the performance of a local contextual processing paradigm, to investigate the proposition that functional disconnection is involved with contextual processing deficits in these populations. To this end, we utilized event-related EEG signals, synchronization likelihood and graph theoretical analysis. Local context was defined as the occurrence of a predictive sequence of stimuli before the presentation of a target event. In the SC patients, we observed a decrease in path length (L) in the beta band, for the predictive sequence and for predicted and random targets, compared with controls. These abnormalities were associated with weaker frontal-temporal-parietal connections. In the PD patients we found longer L (theta band) for predicted targets, and higher cluster coefficients for both the predictive sequence (theta band) and predicted targets (alpha and theta bands), compared with controls. Detection of predicted targets was associated with weaker frontal-parietal connections in PD. No group differences were found for randomized standard stimuli in both SC and PD patients. These findings provide evidence of task-specific functional connectivity abnormalities within frontal networks during local contextual processing., (Copyright © 2013 Elsevier Inc.

Abstract

Objective: We investigated the role of the frontostriatal system in contextual processing, by examining neural correlates of local contextual processing in Parkinson's disease (PD). Local context was defined as the occurrence of a short predictive series of visual stimuli occurring before delivery of a target event., Methods: EEG was recorded in eight PD patients and eight controls. Recording blocks consisted of targets preceded by randomized sequences of standards and by sequences including a predictive sequence signaling the occurrence of a subsequent target event. Subjects pressed a button in response to targets. Peak P3b amplitude and latency were evaluated for targets after predictive and non-predictive sequences., Results: Behavioral and electrophysiological measures showed that controls processed predicted and random targets differentially, while PD patients processed these similarly. Reaction times were shorter for predictable than for random targets in controls but not in patients. PD patients failed to generate the expected P3b latency shift between predicted and random targets, which is observed in controls., Conclusions: These findings show that predictive local context effects on target detection are altered in PD patients., Significance: The findings suggest a key role for the frontostriatal system in contextual processing., (Copyright © 2010 International Federation of Clinical Neurophysiology.

Abstract

Background: Safinamide modulates both dopaminergic and glutamatergic systems with positive effects on motor and non-motor symptoms of Parkinson's disease (PD). The drug utilization study SYNAPSES was designed to investigate the use of safinamide in routine clinical practice, as recommended by the European Medicines Agency. Objective: To describe the occurrence of adverse events in PD patients treated with safinamide in real-life conditions. Methods: The SYNAPSES trial is an observational, European, multicenter, retrospective-prospective cohort study. Patients were followed up to 12 months with analyses performed in the overall population and in patients aged >75 years, with relevant comorbidities and with psychiatric conditions. Results: Of the 1610 patients included, 82.4% were evaluable after 12 months with 25.1% of patients >75 years, 70.8% with relevant comorbidities and 42.4% with psychiatric conditions. During observation 45.8% patients experienced adverse events, 27.7% patients had adverse drug reactions and 9.2% patients had serious adverse events. The adverse events were those already described in the patients' information leaflet. The majority were mild or moderate and completely resolved and no differences were detected between the subgroup of patients. Clinically significant improvements were seen in the UPDRS motor score and in the UPDRS total score in >= 40% of patients, according to the criteria developed by Shulman et al. Conclusion: The SYNAPSES study confirms the good safety profile of safinamide even in special groups of patients. Motor complications and motor scores improved with clinically significant results in the UPDRS scale maintained in the long-term.
