Brain Response to an Intervention Using Guided, At-Home Technology for the Mind (BRIGHT-Mind)

Brain Response to an Intervention Using Guided, At-Home Technology for the Mind - A Randomized, Controlled, Double-blinded, Parallel-group Intervention Study to Assess an At-Home Program for Improving Cognition and Inducing Changes in Brain Structure and Function

The objective of this study is to assess the effectiveness of two digital programs for providing mental stimulation, improving cognition, and inducing changes in brain structure and function.

Description

Inclusion Criteria:

• Subjects 25-80 years of age.
