Laryngeal Dystonia (LD), also commonly referred to as spasmodic dysphonia, is a neurological voice disorder characterized by involuntary dystonic contractions of the laryngeal muscles. Current treatments such as botox and voice therapy only provide temporary relief and thus, the investigators are exploring new strategies to provide long-term, sustained improvement.
To study the effect of micro-catheters which measure and help identify the optimal blood pressure after cardiac arrest to ensure adequate oxygen delivery to the brain.
The CCNA COMPASS-ND study aims to investigate the bases, commonalities, and distinguishing characteristics of Alzheimer disease and related neurodegenerative disorders.
The purpose of this study is to examine the effects of Parkinson's medication on decision making and risk taking in healthy control participants.
This study will test the safety and tolerability of a medium chain triglyceride (MCT) supplement in those with Alzheimer Disease (AD).
This is a multicenter, randomized, open-label phase 2/3 study of Toca 511 and Toca FC versus standard of care that comprises Investigator's choice of single agent chemotherapy (lomustine or temozolomide) or bevacizumab administered to subjects undergoing resection for first or second recurrence (including this recurrence) of GBM or AA. Subjects meeting all of the inclusion and none of the exclusion criteria will be randomized prior to surgery in a 1:1 ratio to receive either Toca 511 and Toca FC (Experimental arm, Arm T) or control treatment with one option of standard of care (Arm SOC).
Current Canadian Clinical Practice guidelines emphasize the need for effective psychosocial adjuncts to pharmacotherapy for schizophrenia (Canadian Psychiatric Association 2005). This randomized control trial seeks to contribute to the body of evidence supporting psychosocial treatments by assessing the effectiveness of metacognitive training (MCT) and cognitive remediation (CR) at treating the persistent positive and cognitive symptoms of schizophrenia.
The purpose of this project is to conduct a proof of concept study in patients with probable Alzheimer's Disease who have mild to moderate hypertension, in order to determine if there is less global brain atrophy over one year, as measured by ventricular enlargement as a primary outcome measure, when patients are randomized to treatment with an angiotensin receptor blocker compared to an Angiotensin Converting Enzyme inhibitor (ACEI).
The main goal of this program of research is to advance our understanding of how the severely damaged brain changes over the first 12-months post stroke. The investigators will determine 'who recovers', 'who does not recover', and 'why'
This trial will enroll patients that have been diagnosed with a transient ischemic attack (TIA) or minor stroke that has occurred within the past 12 hours. Anyone diagnosed with a minor stroke faces the possibility of long-term disability and even death, regardless of treatment. Stroke symptoms such as weakness, difficulty speaking and paralysis may improve or worsen over the hours or days immediately following a stroke. TEMPO-2 is a minor stroke trial for patients presenting within 12 hours of their symptom onset. Patients will be randomized to TNK-tPA or standard of care.
To look at the differences in "social cognition"- the ability to look at the interpret the social world and put yourself in someone else's shoes - between people with depression, people with frontotemporal dementia and healthy controls.
The purpose of this study is to determine the feasibility of conducting a large trial examining the effect on clinical outcome of a liberal red blood cell (RBC) transfusion strategy compared to a restrictive strategy (usual care) in patients with aneurysmal subarachnoid hemorrhage (SAH)
This is a prospective, multicenter, randomized, double-blinded clinical trial exploring the efficacy and safety of rivaroxaban as compared to acetylsalicylic acid in reducing stroke, transient ischemic attack (TIA) and neurocognitive decline, in subjects with non-valvular AF and with low risk of stroke.
To compare the efficacy of MEDI-551 versus placebo in reducing the risk of an NMO/NMOSD attack in subjects with NMO/NMOSD.
The purpose of this study is to assess the safety, tolerability, biomarker and cognitive efficacy of investigational products in subjects who are known to have, or are at risk of having an Alzheimer's disease-causing mutation by determining if treatment with the study drug slows the rate of progression of cognitive impairment and improves disease-related biomarkers.
This study also offers an observational component collecting cognitive assessment data until the availability of an enrolling drug treatment group, referred to as cognitive run-in (CRI).
This double-blind crossover study aims to compare cognitive performance (e.g., working memory, selective attention and cognitive flexibility) of children ages 6-18 years diagnosed with ADHD of the combined type (ADHD-C) or inattentive-type (ADHD-IA) and currently on > 20 mg/day of psychostimulants (psychostimulants) on: a) their current dose of psychostimulants, vs. b) a lower-dose of psychostimulants (half of their current dose).
The perception of music requires coordinated neural activities in distributed multi-functional centers across both hemispheres. The association between musical abilities and other general cognitive functions have been studied in several populations with inconsistent results.
The investigators will conduct a proof-of-concept study to provide preliminary evidence of efficacy of physical exercise dose on ambulatory function in adults undergoing sub-acute stroke rehabilitation.
Frontotemporal Lobar Degeneration (FTLD) is the neuropathological term for a collection of rare neurodegenerative diseases that correspond to four main overlapping clinical syndromes: frontotemporal dementia (FTD), primary progressive aphasia (PPA), corticobasal degeneration syndrome (CBS) and progressive supranuclear palsy syndrome (PSPS). The goal of this study is to build a FTLD clinical research consortium to support the development of FTLD therapies for new clinical trials.
The purpose of this study is to compare abdominal weight gain and fat distribution to changes in brain morphology in people taking antipsychotic medications.
