Active clinical trials for "Dyskinesias"

Heterozygous mutations in the ADCY5 gene cause involuntary early-onset hyperkinetic movements. In addition, patients may have associated psychiatric disorders.There is currently no treatment. As the pathophysiology is linked to ADCY5 hyperactivity, the investigative team has treated patients with caffeine, an antagonist. The investigator wishes to interview patients on the effect of caffeine on their motor symptoms and their overall clinical condition, and on the possible existence of psychiatric comorbidities using phone questionnaires.

There are several factors influencing on balance and movement in individuals with stroke, such as previous stroke, age, bowel incontinence, visuospatial problem. However, those factors involving in postural control and voluntary movement were studied in subacute and chronic phase of stroke, but not in the acute period. The aim of the study is to determine factors for postural control and voluntary movement in individuals with acute stroke and then follow at the first, third, and sixth month.

Primary Ciliary Dyskinesia (PCD) is a rare genetic disorder characterized by dysfunction of motile cilia associated with recurrent infections of the airways, laterality defects (Situs inversus totalis in about 50% of cases) and fertility problems. At present, mutations in > 45 genes associated with PCD and mucociliary clearance disorders have been identified, representing most likely two thirds of all human cases. The aims of this study are: Correlation between nasal NO levels and distinct PCD genotypes Determination of further parameters potentially associated with nasal NO levels in genotyped PCD individuals course of clinical manifestations (e.g. neonatal distress, infections, bronchiectasis) diagnostic results (HVMA, TEM, IF) lung function outcome (FVC, FEV1)

Assessment of a high speed video camera with a green light source for the measurement of ciliary beat frequency (CBF) in the nasal airways of patients. Assessments of the effect of drugs and other therapies on CBF using the study system. Comparison of results with standard methods such as ciliary brush biopsies

Whole genome sequencing of Korean patients with idiopathic bronchiectasis and their family will perform to identify disease-causing variants.

Levodopa is the main drug treatment for Parkinson's disease. Levodopa can cause unwanted and uncontrolled movements called dyskinesias (LID). The severity of these movements can range from subtle to extremely debilitating. These movements may or may not interfere with normal activities such as putting on a coat or brushing ones teeth. Current estimates of the occurrence rate of LID range from 12 % to 100% after one year of levodopa treatment. These estimates used reporting mechanisms such as self-report and doctor-reported. These reporting mechanisms are not reliable. We will use an objective measure of dyskinesia in the first 5 years of treatment for Parkinson's disease. The purpose of this protocol is to use an objective measure to estimate dyskinesia onset.

Parkinson' patients who have not had dyskinesia would be observed for 2 years in a multicenter prospective study with the purposes to clarify the predicting factors of dyskinesia.

Background: Primary ciliary dyskinesia (PCD) is a rare genetic disease characterised by recurrent respiratory infections and subfertility due to dysfunction of cilia (brushes) of the lining cells. Undiagnosed and untreated it can result in an irreversible crippling chronic lung disease. The diagnosis of PCD is a difficult one and involves the complex assessment of ciliary structure and function. Thus, PCD is under diagnosed and appropriate preventative and symptomatic treatment may be denied in many patients. In addition, the gene responsible for PCD is at present unknown, thus preventing pre-natal diagnosis and genetic counseling. Working hypothesis and aims: Recently, it has become apparent that the evaluation of nasally expired nitric oxide (NO) constitutes a simple and non-invasive diagnostic method, which discriminates between PCD patients, PCD carriers and healthy controls at high rate of specificity and sensitivity. Testing is simple and last approximately one minute. We have recently identified a unique isolated Druze population with high prevalence of PCD. The high frequency of disease places this closed community at a high risk of undiagnosed PCD. The aim of this project is to use nasal NO measurement as a screening tool to identify possible undiagnosed cases of PCD and PCD carriers in this high risk Druze population.

Prospective study to quantify the prevalence of possible tardive dyskinesia (TD) in outpatient psychiatry practices in the United States (US), as well as to describe the associated disease burden in a cohort of patients with one or more psychiatric disorders and a cumulative lifetime exposure to antipsychotic medication of three months or more.

Primary Ciliary Dyskinesia (PCD) is a severe genetic disorder caused by various mutations in genes affecting ciliary motility. Various new and complementary diagnostic techniques, including measurements of nasal nitric oxide (NO), Video Microscopy (VM), Immunoflourescence (IF) and genetic analysis have recently been recognized as simpler and more accurate modalities for the diagnosis and characterization of patients with PCD compared to electron microscopy. While considered a rare disease worldwide, PCD is more prevalent among highly consanguineous populations, such as those found in Israel. We hypothesize that using modern state of the art and novel test modalities on a national scale in Israel will improve diagnosis, improve phenotypic-genotypic correlations and create a national registry for PCD.
