Study Comparing Corpus Callosum Atrophy as a Marker of Later Development of Cognitive Impairment in Patients With Multiple Sclerosis

November 30, 2010 updated by: Cantonal Hospital of St. Gallen

Cohort Study Comparing Corpus Callosum Atrophy as a Marker of Later Development of Cognitive Impairment in Patients With Early and Remitting Relapsing Multiple Sclerosis

This study is a cross sectional study of patients diagnosed with clinically isolated syndrome (CIS) and RRMS, who will undergo a series of tests to assess cognitive impairment, fatigue severity and depressive symptoms. Cognitive impairment will be assessed with Multiple Sclerosis Inventory Cognition (MUSIC) and symbol digit modalities test (SDMT), fatigue severity will be measured with the Fatigue Scale for Motor and Cognitive Functions (FSMC) and depressive symptoms with the Beck Depression Inventory (BDI). All tests mentioned above are validated for MS patients. In the second step we will use our large longitudinal database of serial MRI examinations from which a linear measurement of CCI will be retrospectively calculated.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
clinically isolated syndrome
In this study the term clinically isolated syndrome (CIS) is defined according to the Task Force on Differential Diagnosis in MS, as a monophasic presentation of neurological symptoms with suspected underlying inflammatory demyelinating disease (Miller 2008).
remitting, relapsing MS
remitting relapsing MS according to the criteria by Poser (Poser 1983) or McDonald (McDonald 2001)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Multiple Sclerosis Inventory Cognition (MUSIC)
MUSIC is a cognitive screening instrument. It assesses the cognitive core deficit in MS (mental flexibility, attention, information processing speed, memory and inhibitory control) and includes 3 items derived from a factorial analysis to examine cognitive, motor and psychosocial fatigue, respectively.
Annual Corpus Callosum Index decrease
Corpus callosum index (CCI) is an easy to use MRI marker for estimating brain atrophy in patients with MS. Demonstrated correlation of CCI and atrophy has been measured with brain parenchymal fraction.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Corpus callosum Index at baseline
The CCI at baseline will be measured from MRI findings acquired at diagnosis of clinically isolated syndrome.
Time to clinically definite MS
This is the time in months then patients diagnosed with CIS go on to develop clinically definite MS (CDMS). CDMS will be diagnosed if patients fulfill the criteria for remitting relapsing MS according to Poser (Poser 1983) or McDonald (McDonald 2001).
The Symbol Digit Modalities Test (SDMT)
SDMT is an easily administered brief cognitive performance tests. This test emphasizes working memory and speed processing.
Ratio treatment duration to disease duration
The ratio of duration of treatment (DT) to duration of disease (DD): DT/DD. Duration of treatment is the cumulative time of treatment with interferon-beta 1b. Duration of disease starts from the first presentation of MS symptoms

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
