ATH-1017 Treatment in Subjects With Parkinson's Disease Dementia or Dementia With Lewy Bodies (SHAPE...
Parkinson Disease DementiaDementia With Lewy BodiesThis study is designed to evaluate the safety and treatment effects of fosgonimeton (ATH-1017) in subjects with Parkinson's Disease Dementia or Dementia with Lewy Bodies, with a randomized treatment duration of 26 weeks.
Dexmedetomidine in the Treatment of Agitation Associated With Dementia (TRANQUILITY III)
AgitationDementiaA study to determine the safety and efficacy of BXCL501 dosing for episodes of agitation associated with dementia when they occur (given as needed [PRN]), for a maximum of 168 doses within a 12-week treatment period.
DaTSCAN Imaging in Aging and Neurodegenerative Disease
DementiaParkinsonism2 moreThe investigators propose using DaTscan in patients with REM sleep behavior disorder (RBD), mild cognitive impairment (MCI), Parkinson's disease (PD), dementia with Lewy bodies (DLB), Alzheimer's disease (AD), and other neurodegenerative syndromes and disorders, to test several hypotheses - some confirmatory, and some novel. Such use will provide new data on the potential clinical and research utility of DaTscan in neurodegenerative diseases. The findings on DaTscan will be correlated with clinical diagnoses and other multimodal imaging studies (e.g., MRI, MRS, FDG-PET, and amyloid-PET) to enhance our understanding of neurodegenerative diseases.
A Phase 2a Study of TPN-101 in Patients With C9ORF72 ALS/FTD
Amyotrophic Lateral SclerosisFrontotemporal DementiaThis is a Phase 2a study to assess the the safety and tolerability of TPN-101 in patients with Amyotrophic Lateral Sclerosis (ALS) and/or Frontotemporal Dementia (FTD) Associated with Hexanucleotide Repeat Expansion in the C9orf72 gene (C9ORF72 ALS/FTD).
Ambroxol as a Treatment for Parkinson's Disease Dementia
Parkinson's Disease DementiaThe present study will test the hypothesis that the medication Ambroxol is safe and well tolerated and will improve cognitive and motor symptoms of Parkinson's Disease Dementia (PDD). Ambroxol has been shown to raise the levels of the enzyme beta-glucocerebrosidase resulting in lower the levels of the protein alpha-synuclein, both of which have been shown to improve cognition in mouse models. This will be a 52 week trial of Ambroxol in 75 individuals with PDD. Participants will undergo clinical, neuropsychological and neuroimaging assessment throughout the study to assess changes.
Family Telemental Health Intervention for Veterans With Dementia
Dementia Family Caregiver Burden and ConflictDementia impacts Veterans, their families, and other Veterans who serve as caregivers. One of the most stressful aspects of caregiving is the management of behavioral problems (e.g. wandering, agitation, and sleep difficulties), which exacerbate health issues for both caregivers and persons with dementia (PWD). Existing VA caregiver treatments for caregiver stress and behavioral problems are often ineffective. Many caregivers do not realize their interactions with PWD contribute to behavioral problems and thus do not ask for help to improve their interpersonal skills. The aim of this project is to develop an assessment of interpersonal skills deficits and a related treatment strategy to assist family caregivers of PWD who are challenged by a lack of interpersonal skills and are not helped by existing family caregiver treatments. This project, will develop and test (1) a video assessment of caregiver/PWD interaction that clinicians will use to identify interpersonal difficulties and (2) a family therapy for the interpersonal difficulties clinicians identify in the assessment.
The Brain Health Study: A Pragmatic, Patient-Centered Trial
DementiaAlzheimer DiseaseThe eRADAR Brain Health Study seeks to refine and test a novel, low-cost strategy for increasing dementia detection within primary care.
Circulating Ghrelin as a Biomarker for Dementia
DementiaThe primary objective of this study will explore whether circulating acyl-ghrelin (AG) and unacylated-ghrelin (UAG) are reduced in neurodegenerative disease associated with cognitive impairment. It will focus on validating pilot data generated following the analysis of Parkinson's disease (PD), Parkinson's disease dementia (PDD) and healthy cohorts (IRAS project ID: 250933). In addition to the advantages of study replication we will extend the analysis to include two further patient groups that are associated with cognitive impairments, namely, Alzheimer's dementia (AD) and dementia with Lewy bodies (DLB). This study will increase confidence in the replication of our findings. This will be a cross-sectional study using peripheral venous blood.

Molecular Neuroimaging of Neuroinflammation in Neurodegenerative Dementias
Frontotemporal DementiaNeuroinflammation is increasingly implicated as a potential critical pathogenic mechanism in a variety of neurologic and psychiatric disorders. This study will use hybrid PET/MRI imaging to evaluate neuroinflammation and its relationship to cerebral perfusion in frontotemporal dementia (FTD). Patients with FTD will be recruited from the Cognitive Neurology and Aging Brain clinics at Parkwood Institute and will undergo neurocognitive assessment and MRI/PET using the PET ligand FEPPA which binds to activated microglia, a marker of neuroinflammation. Correlations will be conducted to determine whether abnormal neuroinflammation is present in Frontotemporal dementia and whether differential patterns of neuroinflammation are present in different FTD clinical and molecular subtypes, and to determine the relationship between neuroinflammation, cerebral perfusion using arterial spin labeling MRI imaging techniques, and indices of brain structure including volumetric and white matter analysis.
