  Purpose

Patients come to their doctor showing possible symptoms of a movement disorder. It is possible that these symptoms may get worse over time. There is more than one disease that can cause such symptoms. The most common movement disorder illnesses are Parkinson´s Disease and Essential Tremor. Sometimes it is difficult for doctors to make the right diagnosis because the symptoms caused by these illnesses are almost the same. On the other hand the correct treatment for Parkinson´s Disease is different from the correct treatment for Essential Tremor. This study aims to see whether having pictures of the brain taken with DaTSCAN can affect the way the doctor treats these patients and whether it can affect their quality of life directly.

Primary Outcome Measures:
  • Changes That the Doctor Made in the Clinical Management of Subjects Based Upon the Impact of the Imaging Product. [ Time Frame: Changes in clinical management made from Visit 1 (baseline) to Visit 3 (a 3 month period) ] [ Designated as safety issue: No ]
    The impact the Datscan image had on the Doctor's decisions on the clinical management of subjects. A record of the number of changes in the Doctor's clinical management. It is possible for a subject to have multiple changes in Clinical management and other subjects to have no change in their management.


Secondary Outcome Measures:
  • Changes That the Doctor Made in the Clinical Management of Subjects Based Upon the Impact of the Imaging Product. [ Time Frame: From the first patient Visit 1 (1 month) to Visit 4 (12 months). This goes from the baseline (visit 1) up to 1 year post contrast administration. ] [ Designated as safety issue: No ]
    The impact the Datscan image had on the Doctor's decisions on the clinical management of subjects. A record of the number of changes in the Doctor's clinical management. From the first patient visit (baseline) to the fourth patient visit, which was 12 months. This was a 1 year time period being assessed.It is possible for a subject to have multiple changes in Clinical management and other subjects to have no change in their management.
