About this study
Official title: Neuro-anatomical Correlates on Volumetric MRI on the Impact of Brain Reserve and Cognitive Reserve on Ischemic Strokes in Elderly
Ischemic strokes are one of the leading causes of handicap and death in elderly people in France.
Cognitive reserve (CR) is an active model, defined as a function of lifetime intellectual activities and other environmental factors that explain differential susceptibility to functional impairment in the presence of pathology or other neurological insult. CR is estimated using variables for cognitive activity: years of education, professional status, socioeconomic status… Furthermore, brain reverse (BR) is a passive and quantitative model that depend on brain size and other quantitative aspects of the brain that explain differential susceptibility to functional impairment in the presence of pathology.

Firstly, volume and localization of ischemic strokes have a great impact on CR and BR due to brain injury. On the other hand, CR influences the severity and the expression of cognitive diseases.
The investigators realize a prospective study in order to assess the impact of CR and BR on cognitive prognosis after a right middle cerebral artery ischemic stroke in elderly patients.

Questions about this trial
What is this clinical trial studying?
A study testing neurologic and neuropsychological evaluation in people with Brain Ischemia, run by Hospices Civils de Lyon at 1 site in France.
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 3 inclusion and 3 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 20 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
evaluation of cognitive prognosis (time frame: one year post Ischemic stroke). 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 20 Nov 2017.
