Active clinical trials for "Parkinson Disease"

Parkinson diseases (PD) is the second most common degenerative disease of the central nervous system. The development of early diagnostic biomarkers may help identify at-risk individuals and allow precocious interventions at the onset of disease and more precise monitoring of therapies that may slow disease progression. Proof of concept studies indicated significant differences in pupil light response between PD patients and healthy controls. The feasibility of using pupillometry for assesment of PD will be examined.

The most common symptoms associated to senile dementia disease are confusion about schedules, hyperactivity... In this sense, these patients have frequently poor nutrition, resulting in malnutrition problems or malnutrition high risk.

Gait disturbances are very common and are a major cause for losing of independency in patients with advanced Parkinson's Disease (PD). The medical treatment of gait disturbances in advanced PD is very difficult and in many cases the classical dopaminergic treatment has no clinical benefit or even can worsen the instability and increase falls. Rasagiline, a new MAO-B inhibitor who has recently been approved all over the world for the treatment of early and late stages PD has been suggested to have a special effect of gait in patients with advanced PD (LARGO sub-study).

Investigation on how robotically mediated sensorimotor stimulation induces and triggers presence hallucinations in different clinical groups of parkinsonian patients, and in aged-matched controls

To correlate the antegrade effective refractory period of the accessory pathway with its anatomical location in the heart. To investigate whether the accessory pathway location can predict the high risk nature of the accessory pathway

Identify the neural bases of eye movements during visual tasks and their dysfunction at early stages of Parkinson disease (de novo).

Pain (spontaneous pain) is a fundamental non-motor symptom (NMS) of Parkinson's disease (PD) that is prevalent throughout the condition and often unrecognized and undertreated. The study of the scalp laser-evoked potentials (LEPs) (evoked pain) allows a non-invasive exploration of pain central pathways in humans. This technique proved useful in elucidating the physiopathology underlying different pain syndromes. This study has been conceived to study spontaneous pain (and/or evoked pain by laser stimulation) in PD patients (with or without pain) with motor fluctuations under drugs-on (Safinamide Metansolfonato or Rasagilina Mesilato).

The purpose of this study is to investigate issues relating to comfort and tolerance to surface neuro muscular electrical stimulation in a parkinson disease population.

G72 gene is located on the common linkage locus in bipolar disorder and schizophrenia, and it encodes D-amino acid oxidase activator (DAOA). There are evidences that elucidated G72 and D-amino acid oxidase(DAO) together playing a critical role in the pathophysiology of schizophrenia. Recently, reports discovered missense mutations in the DAO (R199W DAO and R38H DAO) are associated with familial amyotrophic lateral sclerosis (FALS), and our preliminary data showed that the level of G72 autoantibody decreases in patients with ALS compared with normal control. Thus, we want to find out whether G72 plays a role in ALS and neurodegenerative diseases including Alzheimer disease and Parkinson's disease. First, we detect G72 protein and its autoantibody in sera of neurodegenerative diseases patients using ELISA and Western blotting, and the data are compared with normal control. We hypothesize the levels of G72 protein and its autoantibody in neurodegenerative diseases are less than those in normal control. Then, we extract genomic DNA of neurodegenerative diseases patients, and use polymerase chain reaction(PCR) to detect single nucleotide polymorphism (SNP) of G72. We aim to detect G72 missense SNP variants presented in ALS, AD and PD.

This observational study aims at identifying gene modifiers of Parkinson Disease (PD) and of treatment response and adverse events of antiparkinsonian drugs. Six hundred PD patients will be followed annually for up to 5 years. A biological collection will be associated with a full clinical assessment of motor and non motor symptoms, medical and treatment history, environmental factors. The association between candidate gene polymorphisms and disease or treatment complications will be analyzed.
