Multiple SclerosisNCT00812474
Regional Cortical Cerebral Quantitative MRI Perfusion Correlation Neurocognition in Multiple Sclerosis
An observational study of Multiple Sclerosis, run by Sunnybrook Health Sciences Centre.
Trial summary
Multiple Sclerosis (MS) is a common disease affecting 1/1000 Canadians. Cognition impairment is reported in 40-65% of patients and is socially and functionally disabling. Although multiple sclerosis is widely regarded as a white matter disease, cortical disease burden is increasingly emphasized. Read more about this study

About this study
Multiple Sclerosis (MS) is a common disease affecting 1/1000 Canadians. Cognition impairment is reported in 40-65% of patients and is socially and functionally disabling. Although multiple sclerosis is widely regarded as a white matter disease, cortical disease burden is increasingly emphasized. Studies confirm that gray matter (GM) disease is grossly underestimated by conventional MRI. Although the cause for MS is unknown vascular impairment is implicated in nerve cell death. Several studies have shown perfusion abnormalities in the central GM and white matter (WM) structure. Severity of perfusion reduction correlates with lesion load, atrophy, MS subtype and disease duration. Further extent of cortical atrophy correlates with neurocognitive impairment. We hypothesize that cortical perfusion is a marker of cortical disease severity and correlates with neurocognitive impairment. To show this we will measure regional cortical perfusion and regional brain and WM lesion volumes in 26 predefined brain regions using a template developed for Alzheimer's disease. Regional perfusion will be correlated with neurocognitive tests validated for MS use. Patients will be divided into impaired and non impaired and perfusion compared controlling for known confounding factors. If confirmed cortical perfusion may be utilized as a surrogate marker of cognitive outcome in therapeutic studies.

Questions about this trial
What is this clinical trial studying?
An observational study of Multiple Sclerosis, run by Sunnybrook Health Sciences Centre.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cognitive Impairment (time frame: Cognitive impairment is assessed on the same day as the MRI scan). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2015.
