Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

During the 2 year award period, we will prospectively enroll 200 patients with idiopathic Parkinson Disease (PD), who meet eligibility criteria below. All patients will undergo a baseline polysomnography (PSG) to diagnose Sleep Disordered Breathing (SDB) and will be asked to complete validated questionnaires to measure Sleep Quality, SDB risk, insomnia severity, daytime sleepiness, presence of restless leg syndrome (RLS), anxiety/depression, and quality of life. Medical records will be reviewed to determine co-morbidities and medication use. Each PD participant will undergo a full neurological examination, including the Unified Parkinson's Disease Rating Scale (UPDRS), the Hoehn & Yahr stage and a battery of neuro-cognitive measures at baseline. Patients with SDB will be offered PAP titration and treatment for 4 months. All patients (SDB [PAP compliant, non-compliant], and no SDB [controls]) will complete repeat neuro-cognitive evaluation, questionnaires, neurological evaluation and UPDRS assessment at 4 month and at 1 year follow-up. PD participants will be assessed in the "on" state in the morning. In the event that a participant goes "off" during testing, a break will be taken and participants will be given the option of taking their medication to return to the "on" state and resume testing or they can return later in the week to complete the evaluation. Although participants will understand the general purpose of the study, they will be blinded to the major study hypothesis. Neuropsychological examiners and the neurologist conducting the neurological exam will be blinded to the SDB status of the patient. Four month follow-up will be staggered according to enrolment date and will be completed by Year 2.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
