Randomized Study of the Effects of Glucose on Cognition in Healthy Young and Elderly People and Parkinson's Disease Patients
Not Provided

This study will determine whether glucose facilitates memory in healthy elderly people and those with Parkinson's disease.

Subjects fast for 8 hours before receiving a test to determine their blood glucose levels. Following this test, subjects are randomized to receive either a glucose or saccharin sweetened drink. A series of memory tests and an additional 3 blood glucose level tests are administered approximately 15 minutes later. A minimum of 1 week afterward, the subjects return and receive the alternate sweetener followed by additional memory tests.
