By following the medical diagnostic, my father’s illness is Parkinson-Plus. However, the SPECT test did not help to support it and it does not show any relevant information about. The doctor says that in 8% of cases SPECT test is invalid and that was our case.
Another point is that doctor said that the test could be repeated in 1 year and not before.
Do you know any link of information regarding SPECT nuclear test and diagnostic of Parkinson-Plus/PSP?
