Memory training is not harmless merely because it looks like a game. Repeated errors can provoke shame or agitation, monitoring can become coercive, stored answers may reveal private routines, and a reassuring score can distract from real-world danger. A safe program protects the person first and treats practice quality as a secondary concern.
Picture a caregiver offering a tablet exercise to someone who becomes visibly upset after missed answers. Increasing the difficulty or insisting on completion would add distress without creating trustworthy evidence. A better response is to stop, reassure the user, review whether participation remains welcome, and keep independent safeguards around medication, cooking, travel, and other consequential activities.
