Preliminary results from twenty-eight of the total thirty-one participants who have completed the trial to date showed that both individuals who received the memory and problem solving training or supportive therapy experienced significant improvements. Improvements were observed on tests of learning and memory and mental flexibility as well as a select basic attention task. Reductions in self-reported social phobia and stigma related to Parkinson’s disease and improvements in self-reported overall quality of life and everyday language, visuospatial, and memory skills were also observed. Participants who received the memory and problem solving training experienced significant improvements on a mental flexibility task. These results were observed even six months after the intervention, which suggests that individuals not only benefit from these therapies, but also can maintain successful use of the strategies on their own.
