Olfactory impairment has been reported in drug-induced parkinsonism (DIP), but the relationship between dopaminergic dysfunction and smell deficits in DIP patients has not been characterized. To this end, we studied 16 DIP patients and 13 patients affected by Parkinson's disease (PD) using the "Sniffin' Sticks" test and [(123)I] FP-CIT SPECT ...

Early diagnosis of Parkinson's disease (PD) is important for putative neuroprotective therapies to be initiated in the earliest stage of the disease. We investigated whether a previously validated timed motor test (TMT) battery could detect subtle motor dysfunction in early PD patients and even in clinically unaffected limbs of strictly ...

Dysphagia is a frequent and early symptom in progressive supranuclear palsy (PSP) predisposing patients to aspiration pneumonia. Fiberoptic endoscopic evaluation of swallowing (FEES) has emerged as a valuable apparative tool for objective evaluation of neurogenic dysphagia. This is the first study using FEES to investigate the nature of swallowing impairment ...

Increasing evidence indicates that processing of proprioceptive information is altered in Parkinson's disease (PD), leading to reduced kinaesthetic and haptic sensitivity. However, there is inconclusive evidence whether dopamine replacement therapy (DRT) ameliorates or worsens kinaesthetic and haptic function in PD. For assessing perceptual function, we employed a task that did ...

It has been postulated that impulsive-compulsive spectrum behaviors (ICBs) in Parkinson's disease (PD) reflect overvaluation of rewards, resulting from excessive dopaminergic transmission in the ventral striatum. However, as the ventral striatum is also strongly implicated in delay discounting, an alternative explanation would be that, similar to stimulant-dependent individuals, PD patients ...

Adipokines such as leptin and adiponectin are adipocyte-specific secretory proteins that play important roles in the metabolic regulation of body weight, insulin resistance and cardiovascular complications. The relationship between the malnutrition-inflammation complex syndrome and high levels of some adipokines in peritoneal dialysis (PD) patients is still unclear. An association between ...

Peripheral neuropathy (PN) is thought to be coincidental in patients with idiopathic Parkinson disease (IPD). We sought to examine the prevalence of PN in a population of IPD patients and a potential relationship to levodopa use and fasting methylmalonic acid (MMA) levels. In a prospective cohort study, IPD patients randomly ...

Treatment-related motor complications such as dyskinesias are a major problem in the long-term management of Parkinson's disease (PD). In sporadic PD, a relatively early onset of the disease is known to be associated with an early development of dyskinesias. Although linked with early onset, patients with Parkin-associated PD often show ...

Differential diagnosis between patients with Corticobasal syndrome (CBS) and Parkinson's disease (PD) may be confusing, particularly in early disease stages. However, in contrast to PD, CBS shows a widespread cortical atrophy that suggests an involvement of the corpus callosum (CC). To test this hypothesis, we used diffusion tensor imaging (DTI) ...

OBJECTIVE: Involuntary eyelid closure (IEC) may occur after deep brain stimulation of the subthalamic nucleus (STN-DBS) in Parkinson's disease (PD) and is often categorised as apraxia of lid opening (ALO), albeit the appropriateness of this term is under debate. To gain insight into the hitherto undefined pathophysiology of IEC after ...

OBJECTIVE: Transcranial sonography (TCS) shows characteristic hyperechogenicity of the substantia nigra (SN) in patients with Parkinson's disease (PD). Although this feature is well established, sufficient observer reliability and diagnostic accuracy are prerequisites for advancements of this method. METHODS: The authors investigated both aspects in a cross-sectional study with four blinded ...

One of the challenges in neuroscience is the detection of directionality between signals reflecting neural activity. To reveal the directionality of coupling and time delays between interacting multi-scale signals, we use a combination of a data-driven technique called empirical mode decomposition (EMD) and partial directed coherence (PDC) together with the ...

Multiple system atrophy (MSA) is a progressive neurodegenerative disease characterized by parkinsonism (MSA-P), cerebellar and autonomic deficits. In Parkinson's disease (PD), an impaired modulation of motor cortical mu and beta range oscillations may be related to the pathophysiology of bradykinesia. Event-related desynchronization (ERD) of these oscillations occur for 1-2 s preceding ...

INTRODUCTION: Patients with advanced Parkinson's disease (PD) often develop motor complications including fluctuations and involuntary movements (dyskinesias). In Denmark, treatment has comprised Deep Brain Stimulation (DBS) since the late 1990s, and as from 2002 use of a subcutaneous apomorphine pump. Monotherapy with continuous intestinal levodopa infusion to the duodenum (Duodopa) ...

DNA variation at the FGF20 gene has been associated with Parkinson's disease (PD). In particular, SNP rs12720208 in the 3' untranslated region (3' UTR) was linked to PD-risk through a mechanism that would implicate a differential binding to microRNA-433 (miR-433). The reduction of the affinity of miR-433 to the 3' ...

Peripheral metabolism of L-DOPA via enzyme catechol-O-methyltransferase (COMT) is one of the possible sources of homocysteine (HCY). The aim of this study was to assess plasma HCY levels in L-DOPA-treated Parkinson's disease (PD) patients and its influence by adding the inhibitor COMT (entacapone). Patients were divided into two groups: (1) ...

Recent cerebral blood flow (CBF) and glucose consumption (CMRglc) studies of Parkinson's disease (PD) revealed conflicting results. Using simulated data, we previously demonstrated that the often-reported subcortical hypermetabolism in PD could be explained as an artifact of biased global mean (GM) normalization, and that low-magnitude, extensive cortical hypometabolism is best ...
