This document summarizes a study that examined the effects of daily cognitive enrichment activities on semantic processing and long-term memory in older adults aged 71-75 over 12 months. The study recruited 30 adults and assigned them to either a treatment group that completed 2 hours per day of cognitive training and puzzles, or a control group that engaged in regular daily activities without cognitive enrichment. Both groups were given pre- and post-tests at 3, 6, 9, and 12 months. The results supported the hypothesis that cognitive enrichment improves memory, inductive reasoning, and semantic processing speed. However, limitations included that participants were not representative of all elderly and those with cognitive declines were excluded. Future research should study if these effects can reduce health service needs
