About this study

Official title: Neurostimulation for Cognitive Enhancement After Stroke (NeuroCog)

Transcranial direct current stimulation has shown promising results in stroke patients. This study is a double blind, sham-controlled clinical trial aiming to compare the long-term effects of stimulation in two different cognitive regions after a stroke. Sixty patients who suffer from chronic strokes will be randomized into 1 of 3 groups: dorsolateral prefrontal cortex, cingulo-opercular network and motor primary cortex (control). Each group will receive transcranial direct current stimulation for 20 minutes for 10 consecutive working days (2 weeks). Patients will be assessed with a Dysexecutive Questionnaire, Semantic Fluency test, categorical verbal fluency and Go-no go tests, Wechsler Adult Intelligence Scale, Rey Auditory-Verbal Learning Test, Letter Comparison and Pattern Comparison Tasks at baseline, after their tenth stimulation session (week 2) and endpoint (week 4). Those who achieve clinical improvement with neurostimulation will be invited to receive treatment for 12 months as part of a follow-up study.

What is being measured

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

  1. Executive Function measured by Dysexecutive Questionnaire (DEX)

    Measured: Change for executive functions at 4 weeks

Secondary outcomes (5)
  1. Verbal Fluency (Semantic Fluency Test)

    Measured: [ Time Frame: Baseline, Week 2 and Week 4 ]

  2. Response inhibition (Go-no-go Test)

    Measured: [ Time Frame: Baseline, Week 2 and Week 4 ]

  3. Executive function (Wechsler Intelligence Scale for Adults)

    Measured: [ Time Frame: Baseline, Week 2 and Week 4 ]

  4. Memory (Rey Auditory Verbal Learning)

    Measured: [ Time Frame: Baseline, Week 2 and Week 4 ]

  5. Processing Speed (Letter Comparison and Pattern Comparison Tasks)

    Measured: [ Time Frame: Baseline, Week 2 and Week 4 ]

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing transcranial direct current stimulation in people with Stroke and Cognitive Impairment, run by Federal University of Paraíba 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 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: status not confirmed, as of the sponsor's last update on 7 Dec 2015. 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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Contact Suellen Andrade (suellenandrade@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Executive Function measured by Dysexecutive Questionnaire (DEX) (time frame: Change for executive functions at 4 weeks). 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 NCT02315807, which also lists 1 linked publication.

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 7 Dec 2015.
