In the last 6 years I have used with hardly any positive effect the following meds: Sinemet CR, Permax, Amantadine, Tremblex, Amytriptyline and Ropinirol. I am going to have a SPECT scan in about two months, because the neuro wants to find out why I do not respond to the meds. There are two possibilities: 1) there are no or not enough receptors to respond; 2) the receptors are there still. If 2, he will try high(er) doses. If 1, I have some form of Parkinsonism. But he wont go into details untill after the scan. BTW: tHere are two types of scans possible: 1) to determine whether or not you have PD (scan focusses on substantia nigra) 2) to see if several other systems and/or receptors work (scan focusses more on striatum, etc.) Hans.
