Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
