Parkinson's Disease and Memory
Parkinson's disease involves both damage to the basal ganglia and certain memory dysfunctions, suggesting that the basal ganglia are involved in specific types of memory. Those who have this disease have problems with both their working memory and spatial memory.
Most people can instantly and easily use visual-spatial memory to remember locations and pictures, but a person with Parkinson's disease would find this difficult. He or she would also have trouble encoding this visual and spatial information into long-term memory. This suggests that the basal ganglia work in both encoding and recalling spatial information.
People with Parkinson's disease display working memory impairment during sequence tasks and tasks involving events in time. They also have difficulty in knowing how to use their memory, such as when to change strategies or maintain a train of thought.

Most people who ski, play professional football or drive race cars, will not dieat least not in the actand yet they are the ones with the glamorous images, the expensive equipment and the mythic proportions. Why this should be I cannot say, unless it is simply that the average American does not know a daredevil when he sees one.”
