Session Title: Parkinson's disease: Cognition
Session Time: 12:00pm-1:30pm
Location: Exhibit Hall located in Hall B, Level 2
Objective: Aim of this study is to assess the alterations in daily behavioral memory for prolongation of disease duration in PD.
Background: We are continuing to examine the cognitive function of patients with Parkinson’s disease.
Methods: Subjects are 104 PD patients who meet the following conditions, Rivermead behavioral memory tests (RBMT) can be measured twice placed between the about every one year, and those who were able to exclude the cause of cognitive decline due to depression for the score is equal to or less than the seven points of the HAM-D.
Results: The average age of the subject was 69.2 ± 8.7 years (first time test), gender was 42 males, 62 females, the average of H-Y severity is 2.7 ± 0.5, the average of disease duration was 7.7 years. In order to examine over time changes in behavioral memory, we compared the average of RBMT scores obtained in the two measurements. The first time 18.5 ± 3.2 points, the second time is 17.9 ± 3.3 points, a significant difference was not observed (p = .62). Both exceeded 16 points a cutoff value of RBMT, it was shown that many of PD patients maintained with behavioral memory. In addition, we have examined the association between disease duration and RBMT score, there was no significant correlation. In order to examine the factors that cognitive function is improved, we compared the characteristics of the two groups with improved RBMT score more than 3 points in the measurement (21 cases) and 3 points or more reduced group (16 cases). As a result, many of the subjects were high activity in the improved group, were often low activity subjects at a reduced group.
Conclusions: PD patients behavioral memory is not changed significantly between about 1 year, there was no association with disease duration. However, activities such as participating in social activity are likely to affect the improvement of the behavior memory.
