Filter by:This study attempts to identify two types of AD by using clinical and cognitive tasks and brain imaging. The subtypes of AD are separated into a "typical" group (memory loss) and a "variant" group (language, visuospatial, and other cognitive difficulties). Performance on the clinical tasks and brain imaging will be compared among the young-onset Alzheimer's disease group, a late-onset Alzheimer's disease group, and a control group.
To establish diagnostic tools to make an accurate clinical and pathological diagnosis of patients with clinical FTLD syndromes
Neuroinflammation 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.
The purpose of this study is to evaluate the effect of 10 sessions of anodal transcranial Direct Current Stimulation (tDCS - 1 mA) applied to left Cortex DorsoLateral PreFrontal (CDLPF) of Alzheimer's or Primary Progressive Aphasia (PPA) patients compared to the application of a placebo tDCS (sham procedure) on cognitive functions, which are evaluated at short term (1 week post-treatment) and mild term (3 weeks post-treatment). After unblinding, patients who received placebo treatment could be received active tDCS.
This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/
This study is designed to learn more about overall tau burden in the brain of patients with Primary Progressive Aphasia (PPA) and Frontotemporal Dementia.
Primary progressive aphasias (PPA) represent a challenging group of degenerative language diseases that has led to growing interest in the scientific and medical community. However, a full-blown cognitive/linguistic, anatomic and biologic characterization of the three main variants remains incomplete given that the available data derive from relatively small patient samples. Such a three-fold characterisation will be an major milestone with the prospective of providing the rationale for therapeutic interventions comprising specific rehabilitations protocols and pharmacological trials. The present study addresses theses issues in the three PPA main variants through a cross-sectional and longitudinal investigation exploring 1) cognitive/linguistic features, 2) anatomic/metabolic specifications (MRI-VBM, MRI-fiber tracking, functional connectivity - MRI resting state, PET), and 3) biologic aspects (CSF biomarkers, genetic screening).
The primary objective of the study is to determine the safety and feasibility of intrathecal administration of DUOC-01 as an adjunctive therapy in patients with inborn errors of metabolism who have evidence of early demyelinating disease in the central nervous system (CNS) who are undergoing standard treatment with unrelated umbilical cord blood transplantation (UCBT). The secondary objective of the study is to describe the efficacy of UCBT with intrathecal administration of DUOC-01 in these patients.
We are trying to identify factors associated with improved quality of life and fewer PD symptoms. We are attempting to identify practices, beliefs, and therapies used by individuals who report excellent quality of life, few PD symptoms, and reduced rates of progression. After agreeing to participate, we will ask participants to fill our questionnaires about their experience with PD, their health in general, along with their food intake every six months for five years.
Although lysosomal storage disorders, such as Fabry disease, Gaucher disease, and Pompe disease, represent serious challenges in the healthcare system, no study has yet investigated the prevalence of these diseases in the US. Frequently, patients show progressive worsening of symptoms for several years before they get diagnosed. Since many of these diseases can be managed therapeutically, it is important to identify and treat patients in order to avoid organ damage. The investigators aim to undertake a screening study that identifies undiagnosed patients with lysosomal storage disorders and determine the prevalence of these diseases with special focus on underrepresented minority groups.
