What difference in claimed outcomes sometimes confuses the general public regarding app objectives?

Reversal of decline versus improvement in baseline function

The varied objectives within the cognitive training industry can lead to public confusion regarding what specific benefits users should realistically expect. This confusion stems largely from the differing claims made by various apps and studies regarding outcomes. Some research highlights results suggesting a significant reversal of previously lost function, potentially equating to reversing years of age-related decline in a key system. In contrast, other applications focus their marketing on demonstrating modest, short-term improvement in the baseline functions, like concentration, for generally healthy adults. This disparity between promising restoration versus mild enhancement makes selection difficult for the average consumer.
