Southend Imaging Study (SIS)

December 21, 2020 updated by: Mid and South Essex NHS Foundation Trust
The study objective is to correlate global cognition and episodic memory performance to resting state fMRI functional connectivity. This is a non-treatment, prospective, natural history data collection study in a cross-sectional cohort of patients with cognitive impairment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

At present, Magnetic Resonance Imaging (MRI) is widely used along with other tests to help diagnose dementia, however diagnosis still remains challenging. There is currently a focus on the usefulness of resting state functionalMRI (RS fMRI) as a way of establishing differences in functional connectivity between healthy subjects and those with various neurodegenerative disorders. Although the potential for RS fMRI to be used as a biomarker for neurological diseases looks promising, further research is needed, especially regarding validation of normal values and seed-based functional connectivity. Further research into this area will help to improve the ability to appropriately classify new subjects and ultimately allow use of RS functional connectivity as a biomarker. This is a nontreatment, prospective, natural history data collection that aims to analyse functional connectivity in a cohort of patients with suspected cognitive impairment. Correlation of global cognition and episodic memory performance to resting state fMRI functional connectivity will be evaluated. Patient population will include patients over the age of 18 with cognitive impairment and age and gender matched controls. Eligible patients will have to complete neuropsychological and clinical assessments and complete an fMRI scan prior to enrolment.Study duration is estimated at 4 years.

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 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with suspected cognitive impairment, mild cognitive impairment, autosomal dominant Alzheimer's disease, late onset Alzheimer's disease, Vascular dementia, Parkinson's dementia and age and gender matched controls.

Inclusion Criteria:

  • Informed consent
  • Cognitive impairment
  • Age from 18 to 100 years
  • On stable medication for 1 month before the screening visit; on or off cholinesterase inhibitors

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
Time Frame
Evaluation of the functional connectivity in the Default Mode Network .
Time Frame: 4 years
Evaluating the correlation of the Default Mode Network functional connectivity to types of dementia.
4 years

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
Time Frame
Correlation of cognitive performance to functional connectivity.
Time Frame: 4 years
To evaluate the correlation between individual measures of functional connectivity and global and episodic cognitive performance as measured by neuropsychological tests.

Primary Completion (Actual)

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.
