It is currently unknown whether speech and limb motor effectors in Parkinson's disease (PD) are controlled by similar underlying brain processes. Based on computerized objective analysis, the aim of this study was to evaluate potential correlation between speech and mechanical tests of upper limb motor function. Speech and upper limb motor tests were performed in 22 PD patients and 22 healthy controls. Quantitative acoustic analyses of eight key speech dimensions of hypokinetic dysarthria, including quality of voice, sequential motion rates, consonant articulation, vowel articulation, average loudness, loudness variability, pitch variability, and number of pauses, were performed...

Therapeutic protein delivery using viral vectors has shown promise in preclinical models of Parkinson's disease (PD) but clinical trial success remains elusive. This may partially be due to a failure to include advanced age as a covariate despite aging being the primary risk factor for PD. We investigated transgene expression following intracerebral injections of recombinant adeno-associated virus pseudotypes 2/2 (rAAV2/2), 2/5 (rAAV2/5), 2/9 (rAAV2/9), and lentivirus (LV) expressing green fluorescent protein (GFP) in aged versus young adult rats...

The risk of falls is higher in patients with people with Parkinsonism (PwP) compared to those without Parkinsonism, and leads to adverse outcomes including fragility fractures. Osteoporosis is under-recognised, and the prevalence of fragility fractures in not well studied. The primary aim of this project is for 100% of new patient referrals to, and 80% of follow up patients within the movement disorder (MD) service with osteoporosis to be treated in accordance with evidence based osteoporosis guidance. Routinely captured information regarding demographics and fragility fractures was retrospectively extracted from the clinical workstation, clinic letters, and clinical coding between July and November 2015...

Mild cognitive impairment in Parkinson's disease (PD) has been linked with functional brain changes. Previously, using functional magnetic resonance imaging (fMRI), we reported reduced cortico-striatal activity in patients with PD who also had mild cognitive impairment (MCI) vs. those who did not (non-MCI). We followed up these patients to investigate the longitudinal effect on the neural activity. Twenty-four non-demented patients with Parkinson's disease (non-MCI: 12, MCI: 12) were included in the study. Each participant underwent two fMRIs while performing the Wisconsin Card Sorting Task 20 months apart...

The monoaminergic systems are the target of several drugs for the treatment of mood, motor and cognitive disorders as well as neurological conditions. In most cases, advances have occurred through serendipity, except for Parkinson's disease where the pathophysiology led almost immediately to the introduction of dopamine restoring agents. Extensive neuropharmacological studies first showed that the primary target of antipsychotics, antidepressants, and anxiolytic drugs were specific components of the monoaminergic systems...

Mammalian retromers play a critical role in protein trans-membrane sorting from endosome to the trans-Golgi network (TGN). Recently, retromer alterations have been related to the onset of Parkinson's Disease (PD) since the variant p.Asp620Asn in VPS35 (Vacuolar Protein Sorting 35) was identified as a cause of late onset PD. This variant causes a primary defect in endosomal trafficking and retromers formation. Other mutations in VPS genes have been reported in both sporadic and familial PD. These mutations are less defined...

We aimed to characterize the parent experience of caring for an infant with neonatal encephalopathy. In this mixed-methods study, we performed semistructured interviews with parents whose infants were enrolled in an existing longitudinal cohort study of therapeutic hypothermia between 2011 and 2014. Thematic saturation was achieved after 20 interviews. Parent experience of caring for a child with neonatal encephalopathy was characterized by 3 principal themes. Theme 1: Many families described cumulative loss and grief throughout the perinatal crisis, critical neonatal course, and subsequent missed developmental milestones...

The pedunculopontine nucleus (PPN) is a rostral brainstem structure that has extensive connections with basal ganglia nuclei and the thalamus. Through these the PPN contributes to neural circuits that effect cortical and hippocampal activity. The PPN also has descending connections to nuclei of the pontine and medullary reticular formations, deep cerebellar nuclei, and the spinal cord. Interest in the PPN has increased dramatically since it was first suggested to be a novel target for treating patients with Parkinson's disease who are refractory to medication...

The success of levodopa and other classes of drugs have meant that most people with Parkinson's disease enjoy a good quality of life for many years. However, despite the availability of several drugs and formulations that can be used as monotherapy and in combination, there are a number of disease features that the current therapies are unable to address. The disease continues to progress despite treatment, patients suffer from a myriad of motor and non-motor symptoms, and a neuroprotective therapy is urgently required...

Cell therapy has attracted considerable interest as a promising therapeutic alternative for patients with Parkinsons disease (PD). Clinical studies have shown that grafted fetal neural tissue can achieve considerable biochemical and clinical improvements in PD. However, the source of fetal tissue grafts is limited and ethically controversial. Human parthenogenetic stem cells offer a good alternative because they are derived from unfertilized oocytes without destroying potentially viable human embryos and can be used to generate an unlimited supply of neural cells for transplantation...

Treatment with continuous infusion of intraduodenal (Duodopa®) levodopa / carbidopa is indicated in patients with advanced Parkinson's disease who have not responded to conventional treatment. We present here the case of a patient with this type of probe that debuted jejunitis. A distal phytobezoar was the main causal agent. This rare complication may be favored in cases of intestinal hypomotility. Treatment involves its withdrawal as soon as possible and replacement by a new probe, which results in healing...

Cyanine dyes, often utilized in dye-sensitized solar cells (DSSC), form a range of molecular species from monomers to large H- and J- aggregates in both solution and when adsorbed at a photoelectrode surface. To determine the relative capability of the different dye species to inject photo-excited electrons into a wideband gap oxide semiconductor, sensitization at a single crystal zinc oxide surface was studied by simultaneous attenuated reflection (ATR) UV-vis absorption and photocurrent spectroscopy measurements...

BACKGROUND/AIM: Neonatal infection can sensitize the adult substantia nigra (SN) to secondary insults, causing a decrease in antioxidant capacity which may lead to Parkinson's disease in adults. We studied the prolonged effect of systemic infection by (i.p.) administration of lipopolysaccharide (LPS) on interleukin (IL)-1β, the antioxidant regulator nuclear factor-erythroid 2-related factor 2 (Nrf2), and the peroxisome proliferator-activated receptor γ coactivator (PGC)-1α in rat SN...

Cigarette smoking is known to be harmful to health, and is considered the main cause of death worldwide, especially in India. Among the well-distinguished diseases related to smoking are, chronic obstructive pulmonary disease, oral and peripheral cancers, and cardiovascular complications. However, the impact of cigarette smoking on neurocognitive and neuropathological effects, including anxiety, Alzheimer's disease, Parkinson's disease, ischemic stroke, and blood-brain barrier dysfunction, still remains unclear...

BACKGROUND: Deep brain stimulation (DBS) of the subthalamic nucleus is an effective treatment for advanced Parkinson disease (PD). However, achieving ideal outcomes by conventional programming can be difficult in some patients, resulting in suboptimal control of PD symptoms and stimulation-induced adverse effects. Interleaving stimulation (ILS) is a newer programming technique that can individually optimize the stimulation area, thereby improving control of PD symptoms while alleviating stimulation-induced side effects after conventional programming fails to achieve the desired results...

Parkinson's disease is an age-associated progressive neurodegenerative disorder that has gained crescent social and economic impact due to the aging of the western society. All current therapies are symptomatic and fail to reverse or halt the progression of dopaminergic neurons loss. The discovery of the capability of neurotrophic factors to protect these neurons lead numerous research groups to focus their efforts in developing therapies aiming at promoting the control of Parkinson´s disease through the delivery of neurotrophic factors to the brain or by boosting their endogenous levels...

OBJECTIVE: The Lewy body dementias (LBD, dementia with Lewy bodies and Parkinson's disease dementia) are the second most common cause of neurodegenerative dementia but remain under-recognised, with long delays from initial assessment to diagnosis. Whilst validated instruments have been developed for key symptoms, there is no brief instrument for overall diagnostic assessment suitable for routine practice. We here report the development of such assessment toolkits. METHODS: We developed the LBD assessment toolkits in three stages...
