Trial summary

This study aims to discover whether acquiring basic-literacy in adulthood can improve episodic memory and brain structural and functional connectivity. In a collaborative project between Brazil and USA, the investigators will use a randomized controlled trial approach to leverage the level of evidence of the benefits… Read more about this study

About this study

This study aims to discover whether acquiring basic-literacy in adulthood can improve episodic memory and brain structural and functional connectivity. In a collaborative project between Brazil and USA, the investigators will use a randomized controlled trial approach to leverage the level of evidence of the benefits of basic adult-education as a possible cognitive reserve builder. If successful, the study's findings will be important in shaping policies targeting increasing access to late-life education to reduce dementia risk.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Literacy trainingBehavioural

    Teaching adults how to read and write using the analytical and phonemic method

  • Non-Literacy trainingBehavioural

    Attending classes in geography, history, sciences, without receiving the specific training in literacy

Study groups in NCT04473235
Study groupRoleWhat they receive
Literacy trainingExperimentalThe basic-literacy training will be given for two hours/day for four days/week for 6 months. At baseline, participants will be randomized into four classes of 30. An expert in adult education will oversee the classes and meet the teachers periodically, and each class will count with a certified and experienced lead teacher and teacher aid. The intervention group will receive literacy training based on analytical and phonemic methods for enabling reading and writing
Receives: Behavioral: Literacy training
Non-literacy trainingActive comparatorThe comparator group will have access to non-literacy classes offered at the adult school, including geography, history, informatics, and sciences, but no literacy-training, for two hours/day for four days/week for 6 months.
Receives: Behavioral: Non-Literacy training

What is being measured

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

  1. Episodic Memory Improvement

    Change in free recall sum-of-attempts of the Free and Cued Selective Reminding with Immediate Recall (FCSR) test.

    The Free and Cued Selective Reminding Test (FCSRT) is an episodic memory test. First, the participant learns 16 figures, 4 each time, with the help of semantic cues provided by the examiner. After that, the participant recalls the figures 3 times, with a distraction activity between each attempt (counting 20 to 1 backwards). The sum of each immediate free recall is called sum of attempts. It ranges from 0 (the participant does not recall any figure in three attempts) to 48 (the participant recalls all the figures). The higher the score, the better the participant's episodic memory.

    Measured: Baseline and 6 months

Secondary outcomes (1)
  1. Change in Brain Connectivity

    The intrinsic functional connectivity will be measured using the BOLD (blood oxygen level dependent) that is calculated through resting state functional MRIs that will be performed at baseline and at 6 months follow up. After preprocessing the images and accounting for potential cofounders (head motion signal, cerebral spinal signal, physiological signal and white matter signal), the BOLD signal is measured and coregistered in T1 images for anatomical correspondence of the signal. Then, a seed is placed in the hippocampus and the BOLD signal between the hippocampus and the prefrontal cortex is calculated at baseline and at 6 months follow up. The higher the value, the more the regions are connected. Change in the intrinsic functional connectivity between the hippocampus and the prefrontal cortex.

    Measured: Baseline and 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Literacy training and Non-Literacy training in people with Memory Impairment, run by University of California, San Francisco 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 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: finished, as of the sponsor's last update on 16 Jul 2024. 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?

Yes. Results are posted in the registry (first posted 16 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Episodic Memory Improvement (time frame: Baseline and 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Jul 2024.
