Three weeks ago i saw a 68 year old man with what i thought was a late onset tremor who had been told he had Parkinsons disease purely on the DAT scan report . There was no bradykinesia, repeat DAT which I felt forced to order was normal. Enormous damage to repair.

Clinical examination is being left behind in favour of “diagnostic” investigations. Thought these tests were to support the demonstrable clinical signs and picture ? !!
@ajlees
Putting our neuroimaging overlords on hold.
Are you implying that there just might be a role for an observant clinician in the 21st century?
Do the students/clerks and residents/registrars know about this?
@ajlees
Exactly the same phenomenon with Alzheimer’s disease (the dementia that is, not the presence of amyloid), “diagnosed” from an MRI scan. But, before we all get too smug, diagnoses made on purely clinical grounds are far from infallible.
@ProfRobHoward
While the new concept of AD, independent of dementia and pathology has a logic for research it is causing mayhem in clinical practice.
We all find it hard to switch hats from scientific knowledge and research to good doctoring. Do no harm
@ajlees
Same in neurodevelopmental services. “Gold standard” assessment tools + diagnostic cut offs = decision on autism. To adapt a turn of phrase “Tools don’t diagnose people, clinicians do”
