Trial summary

The purpose of this study is to evaluate whether or not cerebral atrophy scores obtained from a brain MRI can correlate with Cognitive Test results. These results hope to demonstrate a link between cerebral ischemic/degenerative changes shown on the MRI and cognition functions results. Read more about this study

About this study

The purpose of this study is to evaluate whether or not cerebral atrophy scores obtained from a brain MRI can correlate with Cognitive Test results. These results hope to demonstrate a link between cerebral ischemic/degenerative changes shown on the MRI and cognition functions results.

Read the detailed description

Preliminary evidence indicates that intracranial atherosclerosis may predict incident cerebrovascular events and central atrophy. Age induced changes on cerebral tissue in adulthood is witnessed as atrophy and well know ischemic changes on imaging studies. There is no consensus at this time what constitutes normal, age induced atrophy and pathologic atrophy on imaging studies. The same challenge is also encountered for ischemic cerebral parenchymal change.

Until recently there have been several important limitations in this research 1) Measurement of cerebral tissue loss and amount of ischemic insult was based on a qualitative grading (2) There was no cognitive testing. With Advancements in software technology that have now allowed for measurements of CSF and brain volumes in reliable and reproducible ways and the neuroradiologist having access to the subject's Neurological Cognitive Testing Scores, this study will objectively measure MRI findings and correlate them with the level of cognitive function.

This study will look at subjects who have undergone cognitive testing from the Neurology Clinic and then referred for an MRI brain exam, as standard of care testing. The MRI information will be acquired by volumetric technique for calculation of brain and CSF volumes and MRI data will be plotted against the cognitive test results.

The results of this study will be to correlate quantitative measures of cerebral atrophic and ischemic changes with level of cognition and to establish reliable imaging criteria that can help identify normal, age induced versus pathologic. Information obtained will shed light to cognitive effects and imaging appearance of: Separation of normal age related changes from pathologic states, changes leading to dementia and normal pressure hydrocephalus.

An observational study of Cognitive Decline, run by Lahey Clinic at 1 site in United States.

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 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: stopped early, as of the sponsor's last update on 21 Dec 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 United States. 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 was stopped early (reason given: Investigator left the Institution). Results are not available in the source record.

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?

Correlate quantitative measures of cerebral atrophic and ischemic changes with level of cognition using Mental Status Exam and Brain MRI exam (time frame: One time visit, duration of MRI). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00704327, which also lists 14 linked publications.

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 21 Dec 2017.
