BACKGROUND: Inverse comorbidity is disease occurring at lower rates than expected among persons with a given index disease. The objective was to identify inverse comorbidity in MS. METHODS: We performed a combined case-control and cohort study in a total nationwide cohort of cases with clinical onset of MS 1980-2005. We randomly matched each MS-case with five population controls. Comorbidity data were obtained from multiple, independent nationwide registries. Cases and controls were followed from January 1977 to the index date, and from the index date through December 2012...

Frontotemporal lobar degeneration with transactive response DNA-binding protein 43 (FTLD-TDP) and progressive supranuclear palsy (PSP) are distinct neurodegenerations with different clinical presentations. We report two cases with FTLD-TDP and PSP in comorbidity: a patient with amnestic dementia developing frontal lobe dementia, Parkinsonism and supranuclear gaze palsy and a patient with cerebellar ataxia and nystagmus developing akinesia, rigidity, and subcortical dementia. Neuropathological examination revealed neuronal and glial tau pathology together with ubiquitin, and phospho-TDP-43-immunoreactivities in the hippocampus, striatum, mesencephalon, and frontal and temporal cortices...

The impact of dental amalgam on the development of Parkinson's disease (PD) is still uncertain, although a positive association between dental amalgam and PD has been found in a few case-control studies. The patients with amalgam fillings restored between 2000 and 2008 were identified by using the National Health Insurance Research Database (NHIRD) in Taiwan. The same number of patients who had no new amalgam filling restored was matched by sex, age, and treatment date. Both cohorts were followed up from the treatment date until the date of diagnosis of PD, death, or the end of the year 2008...

BACKGROUND: Punctual delivery of dopaminergic medication to Parkinson's disease (PD) patients may be important in optimizing disease control. We tested the hypothesis that prompt delivery of l-dopa medications to emergency hospital inpatients was associated with a decreased length of stay in hospital. METHODS: The study population consisted of all urgent hospitalizations for patients with a diagnosis of PD to the Royal Derby Hospital over a two-year period. Data were extracted on timing of delivery of drugs, number of co-morbidities and length of stay...

INTRODUCTION: Parkinson's disease (PD) is a progressive, neurodegenerative disorder of multifactorial etiology affecting ∼1% of older adults. Research focused on linking PD to falls and bone fractures has been limited in Emergency Department (ED) settings, where most injuries are identified. We assessed whether injured U.S. ED admissions with PD diagnoses were more likely to exhibit comorbid fall- or non-fall related bone fractures and whether a PD diagnosis with a concomitant fall or bone fracture is linked to worse prognosis...

BACKGROUND: Depression and anxiety remain under-diagnosed and under-treated in those with neurologic diseases such as dementia or Parkinson's Disease (PD). Our objectives were to first, to provide a synthesis of high quality guidelines available for the identification and management of depression or anxiety in those with dementia or PD. Second, to identify areas for improvement for future guidelines. METHODS: We searched MEDLINE, PsycINFO, and EMBASE (2009 to July 24, 2015), grey literature (83 sources; July 24-Sept 6, 2015), and bibliographies of included studies...

BACKGROUND: Parkinson's disease (PD) affects around 100,000 people in England. A number of non-oral therapies can improve both the quality of life and reduce patient needs for health and social care. However, these can be relatively expensive at £2000-£10,000 per year per patient. Our aim was to examine how prescribing of these agents relates to secondary care costs. METHODS: Using practice level primary care prescribing data and hospital episode statistical data in England, we investigated the relation between general practitioner prescriptions of apomorphine injections/rotigotine patches and the secondary care costs accrued for their diagnosed PD patients for 2011-2014...

BACKGROUND: Tourette's disorder and attention-deficit/hyperactivity disorder often co-occur and have both been associated with structural variation of the basal ganglia. However, findings are inconsistent and comorbidity is often neglected. METHODS: T1-weighted magnetic resonance images from children (n = 141, 8 to 12 years) with Tourette's disorder and/or attention-deficit/hyperactivity disorder and controls were processed with the Oxford Centre for Functional MRI [Magnetic resonance imaging] of the Brain (FMRIB) integrated registration and segmentation tool to determine basal ganglia nuclei volume and shape...

Background. While increasing evidence suggests comorbidity of peripheral neuropathy (PNP) and Parkinson's disease (PD), the pathogenesis of PNP in PD is still a debate. The aim of this article is to search the core PD symptoms such as rigidity and tremor as contributing factors to mononeuropathy development while emphasizing each individual patient's asymmetric symptom severity. Methods. We studied 62 wrists and 62 elbows of 31 patients (mean age 66.48 ± 10.67) and 64 wrists and 64 elbows of 32 age-gender matched healthy controls (mean age 62...

BACKGROUND: Despite ongoing progress in our understanding of long-term outcomes following neuromodulation procedures, acute adverse outcomes shortly after deep brain stimulation (DBS) treatment have remained remarkably limited. OBJECTIVE: To identify risk factors associated with acute 30-day outcomes following DBS treatment in Parkinson's disease (PD) patients. METHODS: We evaluated patients who underwent DBS treatment for PD from 2005 to 2014 through the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database...

Cornelis J Van der Schyf
Preclinical Research Neuropsychiatric symptoms are currently recognized as a common burden in patients suffering from Alzheimer's disease (AD), Parkinson's disease (PD), and many other neurodegenerative disorders. Earlier theories positing that these symptoms emerge predominantly in patients with late-stage disease have been largely dismissed. It is now generally accepted that many neuropsychiatric symptoms commonly manifest very early in neurodegenerative disease stages, and in many cases are even considered prodromal indicators...

To analyze whether Physical activity (PA) reduces mortality risk at thirteen years' follow-up in a population-based cohort of Spanish older adults. The NEDICES (Neurological Disorders in Central Spain) is a prospective population-based survey of older adults (age ≥ 65 years) that comprised 5278 participants at baseline. A modified version of the Rosow-Breslau questionnaire was applied to categorize the PA (sedentary, light, moderate and high) and dates of death were collected from the Official Spanish Death Registry...

Pisa syndrome was first described in 1972 in patients treated with neuroleptics. Since 2003, when it was first reported in patients with Parkinson's disease (PD), Pisa syndrome has progressively drawn the attention of clinicians and researchers. Although emerging evidence has partially clarified its prevalence and pathophysiology, the current debate revolves around diagnostic criteria and assessment and the effectiveness of pharmacological, surgical, and rehabilitative approaches. Contrary to initial thought, Pisa syndrome is common among PD patients, with an estimated prevalence of 8...

Several neurodegenerative diseases are driven by the toxic gain-of-function of specific proteins within the brain. Elevated levels of alpha-synuclein (α-Syn) appear to drive neurotoxicity in Parkinson's disease (PD); neuronal accumulation of tau is a hallmark of Alzheimer's disease (AD); and their increased levels cause neurodegeneration in humans and model organisms. Despite the clinical differences between AD and PD, several lines of evidence suggest that α-Syn and tau overlap pathologically. The connections between α-Syn and tau led us to ask whether these proteins might be regulated through a shared pathway...

BACKGROUND: Dexmedetomidine is a selective alpha-2 adrenergic agonist with sedative, analgesic, and anxiolytic properties. Dexmedetomidine has not been approved for use in pediatrics. Dexmedetomidine has been reported to depress sinus node and atrioventricular nodal function in pediatric patients; it has been suggested that the use of dexmedetomidine may not be desirable during electrophysiological studies. AIM: We hypothesize that the use of dexmedetomidine does not inhibit the induction of supraventricular tachyarrhythmias (SVT) during electrophysiological studies and does not inhibit the ablation of such arrhythmias...

: Motor and nonmotor symptoms associated with Parkinson disease place individuals at greater risk of sedentary behaviors and comorbidities. Physical activity is one modifiable means of improving health and reducing the risk of morbidity. We applied a behavioral framework to classify existing research on physical activity and PD to describe the current evolution and inform knowledge gaps in this area. Research placed in phase 1 establishes links between physical activity and health-related outcomes; phase 2 develops approaches to quantify physical activity behavior; phase 3 identifies factors associated with implementation of physical activity behaviors; phase 4 assesses the effectiveness of interventions to promote activity; and phase 5 disseminates evidence-based recommendations...

Parkinsonian signs are common in patients with Alzheimer's disease (AD) of mild degree and predict functional decline, but their relationship with gait speed and balance is unclear. The aims of this study were to describe characteristics of patients with parkinsonian signs among 98 patients with AD of mild degree (with no comorbid Parkinson's disease), and to examine associations between parkinsonian signs with gait speed and balance. A cross sectional study at a memory clinic was conducted. Presence of each parkinsonian sign (bradykinesia, rigidity and tremor) was derived from the UPDRS, regular gait speed was recorded over 10m and balance were assessed using the Mini-Balance Evaluation Systems Test (Mini-BESTest)...

BACKGROUND: A disturbed circadian rhythm seems to be a causal factor in the occurrence of depressive disorders in patients with Parkinson's disease (PD). The circadian rhythm can be restored with light. Therefore, Bright Light Therapy (BLT) might be a new treatment option for depression in PD patients. METHODS/DESIGN: In this double-blind controlled trial, 84 subjects with idiopathic PD are randomized to either BLT or a control light condition. The BLT condition emits white light with an intensity of 10,000 Lux, while the control device emits dim white light of 200 Lux, which is presumed to be too low to influence the circadian rhythm...
