Really, any kind of word or number puzzles work here. The point is to continuously stimulate the brain and keep your recall abilities high. By rotating through the different activities, you’ll stimulate different areas of the brain. This, in turn, helps keep the nerves functioning and healthy.
The puzzles target several sections of the brain. The first is recall. In nearly all puzzles, people need to discover and remember lots of information. In larger puzzles, the information can span days, forcing the player to create long-term memories.
The puzzles also stimulate reasoning and problem solving functions. These are often the first parts of the brain to be damaged in dementia. Encouraging these parts of the brain encourage healthy nerves.
