Is there memory deficit in Parkinson’s disease? Explicit and implicit memory for verbal and action events

• Three experiments examined both encoding and test variable whether there is any memory deficit in patients with Parkinson's disease in comparison with normal controls. In Experiment 1, the effect of encoding enactment was tested in free recall and cued recall. In Experiment 2, the combinations of enactment/non enactment and well/poorly integration variables were used at encoding. Again, the subjects were tested by free and cued recall. In Experiment 3, recognition memory and sentence-fragment completion tests were used with the same encoding manipulations as in Experiment 2. In general, the results of all three experiments showed no difference between PD patients and normal controls indicating that there is no memory deficit for PD patients. However, it was observed that there was some recognition deficit (especially for well integrated and verbal items) in Parkins on patients. It was suggested that the similarity between encoding and retrieval and the stage of disease should be considered as important factors for any possible memory deficit in Parkinsonian patients. It was also concluded that Parkinson patients are less well able to utilize cognitive support.
