Brief 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 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.

Arm Intervention/treatment
Experimental: Literacy training
The 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
Behavioral: Literacy training
Teaching adults how to read and write using the analytical and phonemic method

Active Comparator: Non-literacy training
The 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. After 6 months, the groups switch, so the comparator receives the specific reading and writing training, and the intervention group receives the lessons on other themes.
Behavioral: Non-Literacy training
Attending classes in geography, history, sciences, without receiving the specific training in literacy




Primary Outcome Measures :
  1. Episodic memory improvement [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Brain connectivity improvement [ Time Frame: 6 months ]
    Change in hippocampus-prefrontal cortex functional and structural connectivity
