BACKGROUND: Parkinson's Disease Nurse Specialists (PDNS) play an important role in the care for patients with Parkinson's disease (PD) and their caregivers. Until now, there were no nursing guidelines in PD, and interventions were based solely on daily clinical practice because there is no evidence to support the merits of nursing interventions. Consequently, there is little uniformity in current care delivery. OBJECTIVE: Developing a guideline for PDNS. METHODS: We developed a guideline based on a questionnaire among PDNS and a literature review, supplemented with expert opinion plus the input of patients and caregivers...

BACKGROUND: Recent evidence suggests that glucosidase beta acid (GBA) mutations predispose Parkinson's disease (PD) patients to a greater burden of cognitive impairment and non-motor symptoms. This emerging knowledge has not yet been considered in patients who have undergone deep brain stimulation (DBS); a surgery that is generally contraindicated in those with cognitive deficits. OBJECTIVE: To explore the long-term phenotypic progression of GBA-associated PD, in a DBS cohort...

BACKGROUND: Mood disorders are very frequent in Parkinson's Disease (PD), and their effective treatment is still a major unresolved issue: growing evidence suggests that glutamatergic system dysfunction is directly involved. Safinamide is a drug with an innovative mechanism of action, dopaminergic and non-dopaminergic, that includes the reversible inhibition of the monoamine oxidase-B (MAO-B) enzyme and the modulation of excessive glutamate release through the use- and state-dependent blockade of the sodium channels...

BACKGROUND: Polyneuropathy (pnp) is recognized as a clinical feature of Parkinson's disease (PD). Whether pnp is a result of the alpha-synucleinopathy or related to treatment is debated. Previous studies support underlying disturbances in the methionine cycle mediated by L-dopa. OBJECTIVE: Describe possible relationships between methionine cycle metabolism and the development of pnp in L-dopa treated PD. Furthermore, we aim to investigate possible genetic risk factors by genotyping specific SNPs in enzymes involved in the abovementioned pathways...

BACKGROUND: Empathy describes the ability to infer and share emotional experiences of other people and is a central component of normal social functioning. Impaired empathy might be a non-motor symptom in Parkinson's disease (PD). OBJECTIVE: To examine empathic abilities and their relationship to clinical and cognitive functioning in PD patients. METHODS: Empathy was measured in 75 non-demented PD patients and 34 age-matched healthy controls using a German version of the Interpersonal Reactivity Index...

BACKGROUND: Recent genetic and epidemiological studies have shown that there is a link between essential tremor and Parkinson's disease (PD). However, there is a lack of data about the clinical features of PD developed from essential tremor. OBJECTIVE: To explore and describe the clinical characteristics of Parkinson's disease developed from essential tremor (ET-PD). METHODS: Twenty-five ET-PD patients and 124 IPD controls were enrolled according to each criterion...

BACKGROUND: PSP, like Alzheimer's disease (AD), is a tauopathy. The etiopathogenesis of PSP is not well known and the role of stress has not yet been examined. Recent studies have shown that stress increases the risk for developing AD. This study investigates the role of stress as a risk factor for PSP. OBJECTIVE: B To examine the association between the development of progressive supranuclear palsy (PSP) and self-reported life stressors. METHODS: 76 patients diagnosed with PSP according to the NINDS-SPSP criteria and 68 age-matched unrelated controls were administered a life stressor questionnaire...

BACKGROUND: Gastrointestinal symptoms are a well-recognized and common premotor feature of Parkinson's disease (PD). Moreover, multiple studies have assessed the value of colonic α-synuclein as a potential marker of prodromal PD. Recently, the International Parkinson and Movement Disorders Society (MDS) defined research criteria for prodromal PD. OBJECTIVE: The aim of our study was to test the MDS research criteria in patients undergoing diagnostic colonoscopies as potential candidates for inclusion in prospective trials evaluating colonic biopsies as a potential biomarker of prodromal PD...

BACKGROUND: Parkinson's disease (PD) is among the most prevalent neurodegenerative conditions. While motor and non-motor aspects of this disease have been well characterized, no objective biomarker exists to support an accurate clinical diagnosis. However, newer imaging techniques, including [123I]-FP-CIT (DaTSCAN), have demonstrated utility in differentiating between PD and non-neurodegenerative tremor disorders. OBJECTIVE: DaTSCAN has been primarily investigated in situations where diagnostic confusion exists, and in these instances has been shown to significantly impact clinical management...

BACKGROUND: Recent evidence suggests that Parkinson's disease (PD) is associated with intestinal microbiota dysbiosis, abnormal intestinal permeability, and intestinal inflammation. OBJECTIVE: Our study aimed to determine if these gut abnormalities are present in another synucleinopathy, multiple system atrophy (MSA). METHODS: In six MSA and 11 healthy control subjects, we performed immunohistochemistry studies of colonic sigmoid mucosa to evaluate the intestinal barrier marker Zonula Occludens-1 and the endotoxin-related inflammation marker Toll-like-receptor-4 expression...

BACKGROUND: Camptocormia, a disturbance of posture, is a well-described clinical feature of PD and other parkinsonian syndromes. Previous reports have shown that DBS of the subthalamic nucleus (STN) or globus pallidus internus is effective in treating camptocormia. However, the efficacy of DBS for camptocormia varies. OBJECTIVE: To determine a clinical marker for selecting an appropriate therapy for camptocormia, a disabling manifestation of Parkinson's disease (PD) that has a variable response to systemic and local therapies...
