Can anyone tell me if a brain scan and a DAT scan are the same thing? My Neurologist is concerned as tremors are focalised, in right hand and arm only
A brain scan are brain-imaging scans that can tell your specialist what the structure of your brain looks like. Whereas a Datscan is a scans that can tell your specialist how different areas of the brain are working. That, in a nutshell, is the main the difference; however, we go into in a lot more detail on our website here - https://www.parkinsons.org.uk/information-and-support/how-parkinsons-diagnosed.
I hope this answers your question.
