Different professionals weigh different factors, and the authorities below are better guides than we are. The Alzheimer's Association's published caregiver guidance points to activities the person has always enjoyed, adjusted to current abilities, broken into simple easy-to-follow steps, with attention on the process rather than the result. In practice that points toward: familiar shapes (the brain does not have to work to recognize them); pieces large enough to grip without dexterity strain; low setup and low cleanup; activities that have no single right answer, so the person cannot feel they are failing; and activities that invite a partner, someone to share the piece, the puzzle, or the conversation that comes with it. The Alzheimer's Association publishes guidance on activities that engage the mind for people living with dementia at
alz.org. The American Occupational Therapy Association at
aota.org is a useful resource if you want to understand what an OT working in memory care actually does. These pages and the people behind them are far better authorities than a puzzle-maker is. Our role is to make pieces that hold up to the hand and to ship them quickly when an OT or family member identifies something useful.
