Parkinson?s disease is a brain disease whose medical treatment and remedy have not been established yet, although a cause of this disease is considered to be the insufficient formation and action of dopamine, which plays a role of great importance in brain activity. For this reason, there is an increasing demand on the clinical database pertaining to Parkinson?s disease which multiple hospitals and research institutions can share to accumulate knowledge and know-how on the disease. In this paper, we present a clinical database for Parkinson?s disease research and diagnosis which we have preliminary built, especially focusing on the access control and data filtering mechanisms built in hope that medical Grid services are seamlessly integrated to the database in future.
