I asked ChatGPT your question:
1. What a DaTscan actually measures
A DaTscan looks at dopamine transporter activity in a part of the brain called the Striatum.In classic Parkinson’s disease, dopamine-producing neurons gradually die, so the scan usually shows reduced dopamine uptake.
So normally:
• Abnormal DaTscan → supports Parkinson’s
• Normal DaTscan → suggests something else
But it isn’t perfect.
