Yes, this does happen! A DaTscan is a useful tool, but it's not the final word on a Parkinson's diagnosis. It can support a diagnosis, but a normal result doesn't automatically rule it out.

- Loss of smell, which is a very common early Parkinson's symptom

It's always worth having an open conversation with your neurologist about what the DaTscan results mean in the context of all your other symptoms and test results. Every case is unique!
