    Clinical Trial Protocol: Alzheimer's Dementia Underlying Encephalopathy

    Testing whether a blood test can find Alzheimer’s causes of dementia in hospital patients

    📍 Cumberland Medical Center · Crossville, TN · +5 more US sites · Get directions →

    The goal of this clinical trial is to determine if utilizing the Quest AD-Detect blood test, while patient's are hospitalized for a cognitive diagnosis (such as delirium or encephalopathy), will result in an earlier diagnosis of underlying Alzheimer's disease. * Will this blood test have the ability to distinguish between Alzheimer's disease and other causes of cognitive impairment in the inpatient setting?

  • Dementia / Alzheimer's

    A Study of Neurodegeneration and Neuronal Fluctuations in Lewy Body Disease and Alzheimer's Disease

    Studying brain wave, muscle, and memory changes in dementia

    📍 Mayo Clinic Arizona · Scottsdale, AZ · Get directions →

    The purpose of this research study is to investigate how the brain, memory, thinking, and motor behavior change both in individuals with movement and/or cognitive disorders, as well as healthy individuals. Researchers will look at measurements of memory, thinking, brain wave and muscle activity, daily functioning, and brain scans to learn more about brain disorders such as Alzheimer disease and Lewy body disease.

    Swallowing Impairments in Adults With and Without Alzheimer's Disease

    Testing whether adults with Alzheimer’s disease have more swallowing problems than other older

    📍 Vanderbilt University Medical Center · Nashville, TN · Get directions →

    This research study is investigating whether people with Alzheimer's disease (AD) experience more changes to swallowing than their healthy age-matched peers. The prevalence of swallowing impairments in moderate-severe AD is high (85-93%), yet little is known about how swallow function evolves throughout the disease course in people with AD.

  • Parkinson's disease

    A Phase 2 Study and Open-Label Extension of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease

    Testing a treatment in people with early Parkinson’s disease who have an LRRK2 gene test result

    📍 Banner Sun Health Research Institute · Sun City, AZ · +39 more US sites · Get directions →

    The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 40-80 years with early Parkinson's Disease (PD) who have predicted elevations in the activity of the "leucine-rich repeat kinase 2" ("LRRK2" for short) pathway based on their genetic profile. A DNA test will be used to identify the "LRRK2-driven" population with predicted elevation in the LRRK2 pathway.

    Effects Of Osteopathic Manipulative Medicine(OMM) On Lower Extremity Muscle Characteristics In Parkinson's Disease(PD) Patients

    Testing osteopathic treatment to see how it affects leg muscles in Parkinson’s

    📍 NYIT College of Osteopathic Medicine · Old Westbury, NY · Get directions →

    The purpose of the study is to investigate the effects that Osteopathic Manipulative Medicine has on lower extremity muscle characteristics in PD. Muscle stiffness, range of motion, and gait will be measured.

  • Parkinson's disease

    📍 University of Kentucky · Lexington, KY · Get directions →

    The investigators propose a Phase I single surgical-center, double-blinded randomized parallel clinical trial involving bilateral autologous peripheral nerve tissue (PNT) delivery into the NBM or the alternate target also affecting cognition in this population, the substantia nigra (SN), to address "repair cell" support of these areas. Twenty-four participants with idiopathic Parkinson's Disease (PD) who have selected, qualified and agreed to receive as standard of care deep brain stimulation (DBS) will be enrolled and randomly allocated to receive bilateral PNT deployment to either the NBM or SN at the time of DBS surgery.

    Moderate Versus High Volume Light-Moderate Intensity Exercise for People With Moderate Parkinson's Disease

    Comparing lower versus higher amounts of light exercise for Parkinson’s

    📍 Atlanta VA Medical and Rehab Center, Decatur, GA · Decatur, GA · Get directions →

    Veterans with mid to later stage Parkinson's disease (PD) may not be able to work out as hard as they need to, to prevent brain cell loss. Maybe they could work out longer and more frequently to make up for this during their good times and good weeks and then rest during the bad weeks.
