Yes your right i haven't been diagnosed fully and i hope i have made that clear along the way.
my Neuro has held back from a final diagnosis but says strongly after my first and my last visit 'some if not all my symptoms could be due too young onset' but 'not all the features are present in which he would like too make a diagnosis'
he has had a problem with my age at 44, but reading the forum i'm certainly not alone and it is not as rare as he points out in my visits too him.
hence the 'dat scan' which he also said could also show nothing and still the possibility remains.
I guess he's doing everything by the book even though i have two core elements, tremor at rest, slowness of movement, and other problems associated with, fatigue,pain,balance,movement, memory & thinking problems, and last but not least my hand writing has changed beyond my own recognition.
At the end of the day, i've had a test for every thing else over the course of a year ,if he's removed the possibility of it being something else then only one thing remains.
