My best guess- is Positron Emission Tomagraphy (PET) Tau- not something I can order in my neck of the woods and pretty cutting edge but clearly the way things are headed. They also have PET amyloid for Alzheimers- I am not able to order that either :(

We’ve had family with vascular dementia and Alzheimers. None of them ever had/have had a PET scan. Plenty of CTS and MRIs, but the diagnoses were made without the use of a PET. We’ve also been told that a definitive diagnosis could only be obtained with an autopsy. If that last bit is accurate, makes me wonder how the diagnosis of CTE is being made.
