This study is looking at ways to improve thinking abilities (cognitive abilities) in people aged 50 and older who have cognitive difficulties. These difficulties can come from normal aging, neurodegenerative diseases, or other conditions. Researchers are testing two main approaches: cognitive rehabilitation, which uses methods to improve everyday tasks, and transcranial electrical stimulation (TES). TES involves using small amounts of electricity on the scalp to try and change how the brain works. You might receive active TES (tDCS or tACS), sham (inactive) TES, or a cognitively based intervention, or a combination. The goal is to find the best ways to use these methods to help with attention, learning, memory, finding words, and problem-solving.

Study design

This interventional study plans to enroll 500 participants aged 50 and older. It uses a crossover design, meaning some participants may receive both active and sham (inactive) treatments.

What's involved

Participants may receive up to 260 sessions of active or sham transcranial electrical stimulation (tDCS or tACS) and/or a cognitively based intervention. Side effects will be measured immediately after TES sessions.

Compensation

Not stated in the trial record.

Follow-up

Side effects are measured immediately after TES sessions. The record does not specify long-term follow-up after treatment.
