BACKGROUND Visual hallucinations are commonly seen in various neurological and psychiatric disorders including schizophrenia. Current models of visual processing and studies in diseases including Parkinsons Disease and Lewy Body Dementia propose that Acetylcholine (Ach) plays a pivotal role in our ability to accurately interpret visual stimuli. Depletion of Ach is thought to be associated with ...

Motivation: A bioinformatics platform is introduced aimed at identifying models of disease-specific pathways, as well as a set of network measures that can quantify changes in terms of global structure or single link disruptions.The approach integrates a network comparison framework with machine learning molecular profiling. The platform includes different tools combined in one Open Source pipe...

OBJECTIVE Subthalamic nucleus (STN) deep brain stimulation (DBS) is an effective treatment of choice for patients with advanced idiopathic Parkinson's disease (PD) who have motor complication with medication. The objectives of this study are to analyze long-term follow-up data of STN DBS cases and to identify the factors related to outcomes. METHODS Fifty-two PD patients who underwent STN DBS...

BACKGROUND/AIM Selective serotonin reuptake inhibitors are the most commonly chosen antidepressants in patients with Parkinson's disease (PD). The aim of our study was to assess the influence of fluoxetine (Flu) on motor functions in patients with PD. METHODS In this prospective, controlled, open-label study, 18 patients with PD and mild depression [(10 < or = Hamilton Rating Scale for Depres...

Deep brain stimulation (DBS) has been widely used to control motor symptoms and improve quality of life in patients with Parkinsons disease (PD). Recently, DBS in the subthalamic nucleus (STN) has become the preferred target for patients with mixed motor symptoms. Despite resultant motor and quality of life improvements, the procedure has been associated with cognitive decline, mainly in langua...

Astrocytes, which have various important functions, have previously been associated with Parkinsons disease (PD), particularly in 1-methyl-4-phenylpyridinium (MPP+) and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) models of PD. MPP+ is the toxic metabolite of MPTP and is generated by the enzymatic activity of monoamine oxidase B, which is predominantly located in astrocytes. MPP+ acts as...

Cet article rend compte des écarts entre les ambitions initiales d’un projet de recherche international visant le développement d’objets connectés pour l’accompagnement personnes vivant avec la maladie Parkinsons au cours sa mise en œuvre France. Nous y présentons composition du collectif hybride, ses objectifs et enjeux auxquels il est confronté. Les modalités prise savoirs expérientiels sont ...

BACKGROUND We compared uptake of hospital and community-based support in elderly people disabled by chronic obstructive pulmonary disease (COPD), normal controls (NCs) and patients with Parkinsons disease, stroke, amputation, or arthritis (disabled controls; DCs). METHODS There were 65 subjects (35 men) aged 70-93 years (mean 78) with COPD, 55 NCs [23 men; age range 71-90 years (mean 78)] and...
