Presentation and history

A successful graphic designer began to have trouble finding names for people and objects. He continued to design brochures and logos for small businesses but had trouble filling out paper orders, making frequent spelling mistakes. Surprisingly, he was caught stealing a shiny necklace from a client's store. Soon afterward he began to comb the beach, spending many hours looking for seashells. While at home he began to play solitaire compulsively for 6 hours per day. He developed a new interest in squash, and his game steadily improved. He stopped working as a graphic designer but obtained a courier job and learned and remembered a complex route for delivering packages. There was no family history of dementia.
