asymmetry of tracer within the putman - DAT scan question

Recommended Posts

Hi,

 

I recently had a DAT scan done and the result came back.  I must admit I have tried to understand it and read it, however I am lost.

 

Do the areas of the caudate nuclei and the putman determine if one has parkinsons?

 

Thank you for your assistance.

All the DAT tells you is whether there is a dopamine transporter deficit.  In Parkinson it typically looks worse (less update) on one side compared to the other; however an abnormal DAT does not diagnose Parkinson's disease.  It tells you you have a dopaminergic deficit and there is a possibility it is PD.

I greatly appreciate your response Dr. Okun.

 

I was recently undiagnosed based upon a dat scan which indicated I had asymmetry of tracer uptake within the left putman.

 

I am so frustrated right now.  Don't get me wrong, I am very happy not to have it, however my family doesn't understand when I am on Sinment, which I am so much more active.  The doctor feels that it is a placebo effect.  Personally, that doesn't make any sense to me since I was on other medications and nothing worked until I was placed on it.

 

Two other doctors said I had Parkinson's, then this doctor felt the same way until the DAT scan.  So frustrating.

Dopaminergic deficit or problem on a scan does not offer a specific diagnosis though the majority of cases will be Parkinson's disease.
