    Aβ Dynamics in LLMD

    Testing how treating depression may change brain markers linked to Alzheimer’s

    📍 NYU Langone Health · New York, NY · +1 more US site · Get directions →

    This study will examine the biological factors that may modulate the relationship between depression and the development of Alzheimer's disease (AD). Since the direction of causation between depression and the biological factors associated with AD is unknown, the only way to understand cause and associated risk is to treat the depressive symptoms and examine the effects on AD biomarkers.

    Cortical Electrophysiology of Response Inhibition in Parkinson's Disease

    Studying how deep brain stimulation in Parkinson’s affects brain control of stopping actions

    📍 Emory University Hospital · Atlanta, GA · +1 more US site · Get directions →

    Patients with Parkinson's Disease will be studied before, during, and after a deep brain stimulation implantation procedure to see if the stimulation location and the size of the electrical field produced by subthalamic nucleus (STN) DBS determine the degree to which DBS engages circuits that involve prefrontal cortex executive functions, and therefore have a direct impact on the patient's ability to inhibit actions.

    BOOST-PD A Naturalistic Study on IPX-203 for Parkinson's Disease

    Testing a new long-acting levodopa dose to improve “on” time in Parkinson’s

    📍 Cleveland Clinic · Cleveland, OH · Get directions →

    The purpose of this study is to evaluate the effect of IPX203 (Crexont®) - the newest extended-release levodopa formulation - on the duration and quality of good on time, using a wearable device to monitor symptoms. 'Good on time' refers to a period (minutes to hours) when a patient experiences optimal symptom control due to effective medication and has better overall functioning without troublesome dyskinesias.

    A Study of Zunveyl on Safety, Tolerability, Neuropsychiatric Symptoms, and Caregiver Distress in Alzheimer's Disease (RESOLVE)

    Testing the safety and side effects of Zunveyl in people with mild to moderate Alzheimer’s

    📍 Tekton Research Saint Louis Psychiatry · St Louis, MO · Get directions →

    The primary purpose of this study is to evaluate the safety and tolerability of Zunveyl® over 12 weeks of routine clinical use in adults with mild to moderate Alzheimer's disease.

    Lemborexant for Insomnia in a Patient With Dementia: An N-of-1 Trial

    Testing a sleep medicine for insomnia symptoms in a person with dementia

    📍 Nova Scotia Health · Halifax, Nova Scotia · Get directions →

    Insomnia is a highly common, chronic disorder that is distressful for the patient but also for caregivers and can give rise to a heavy burden on the healthcare team. Sleeping aids like benzodiazepines and other sedatives (e.g., zolpidem, zopiclone) have been widely used to help treat insomnia.

  • Parkinson's disease

    Pimavanserin vs. Quetiapine for Treatment of Parkinson's Psychosis

    Comparing treatments to see which works better for hallucinations in Parkinson’s disease

    📍 Southern Arizona VA Health Care System, Tucson, AZ · Tucson, AZ · +23 more US sites · Get directions →

    Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions).

  • Dementia / Alzheimer'sParkinson's disease

    Elucidating the Role of Cholinergic Degeneration in Cognitive Fluctuations in Lewy Body Dementia

    Studying how nerve cell loss affects thinking ups and downs in Lewy body dementia

    📍 Virginia Commonwealth University · Richmond, VA · Get directions →

    The proposed study aims to address the critical gaps in understanding the mechanisms of CF (Cognitive Fluctuations) by leveraging recently emerged molecular biomarkers, advanced neuroimaging techniques to assess measures of cholinergic degeneration, and synchronous EEG and assessments of attention. One of the overarching innovations of study is combining all of these assessments into one integrated research plan

  • Parkinson's disease

    Personalized Real-Time DBS and PD Mechanisms

    Studying how closed-loop deep brain stimulation and levodopa affect Parkinson’s motor symptoms

    📍 Cleveland Clinic · Cleveland, OH · Get directions →

    A prospective cohort of patients scheduled to undergo deep brain stimulation (DBS) implantation surgery for the treatment of Parkinson's disease as per standard of care will be invited to participate in this study. This mechanistic study is aimed at better understanding the role of basal ganglia beta band (11-35 Hz) oscillations and resonance in the manifestation of Parkinson's disease (PD) motor signs using closed-loop electrical neurostimulation, levodopa medication, and computational modeling.

    Nighttime Agitation and Restless Legs Syndrome in People With Alzheimer's Disease

    Studying nighttime agitation and restless legs in people with Alzheimer’s

    📍 The University of Texas at Austin · Austin, TX · Get directions →

    Nighttime agitation in persons with Alzheimer's disease causes patient suffering, distresses caregivers, and often results in prescriptions for harmful antipsychotics. Effective treatments are lacking because of limited knowledge of the etiology of nighttime agitation.

    Measuring serotonin 2A brain receptor activity in people with Parkinson’s

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

    It is hypothesize that patients with clinically diagnosed neurodegenerative diseases will have significantly different receptor occupancy of 5HT2A receptors compared to a healthy age/sex-matched control group. This will be tested by measuring 5HT2A receptor density using the PET radioligand (R)-\[18F\]MH.MZ in both populations.
