About this study

Official title: Neural Correlates and Functional Connectivity Associated With Cognitive Memory Training in Patients With Cerebral Ischemic Lesions

The study aims to investigate the behavioral effects, neural correlates and functional connectivity of cognitive training in patients with stroke

Read the detailed description

The study will investigate the effects of two cognitive training strategies on behavior, neural correlates and functional connectivity of patients with vascular lesions. The first strategy is associated to the ability to apply efficient organizational semantic category strategy to a list of words. This strategy will be trained in activities similar to everyday life activities. There will be in total 5 sessions, two for measuring the generalization effects before and after training and three sessions to apply the semantic strategy in order to improve encoding and episodic memory performance. The second strategy is related to the ability to remember face-names and the strategy will involve the identification of a salient face feature, creation of a nickname and association of the nickname to the real name. There will be 5 sessions in total, two for measuring the generalization effects before and after training and three sessions to apply the face-name association strategy in order to improve encoding and episodic memory performance. These two cognitive training procedures will be carried out in two separate moments. Before and after each procedure all participants will be examined by functional MRI during resting state and during a active task using a memory encoding paradigm. The same procedure will be carried out with normal control participants.

What is being measured

The primary outcome is the main question the study is designed to answer.

    Hopkins Verbal Learning Test (episodic memory test total immediate score 48 and delayed score12) and fMRI active task (news recall immediate and delayed score 12)

    Measured: up to 24 weeks after intervention

Secondary outcomes (1)
  1. Change from baseline everyday life activity performance at 6 months

    Generalization questionnaire (questions on difficulties in everyday memory total score 12)

    Measured: up to 24 weeks of intervention

Questions about this trial

What is this clinical trial studying?

A study testing Cognitive training in people with Vascular Diseases, run by São Paulo State University at 1 site in Brazil.

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: status not confirmed, as of the sponsor's last update on 28 Nov 2023. 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 Brazil. 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?

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?

Change from baseline memory performance at 6 months (time frame: up to 24 weeks after intervention). 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 NCT03644290, which also lists 2 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 28 Nov 2023.
