Abstract
Nigrostriatal dopaminergic function and cerebral energy metabolism were measured with PET in two brothers with early-onset parkinsonism caused by mutation of the parkin gene. Energy metabolism did not differ, but the nigrostriatal dopaminergic pattern was clearly different than that of sporadic PD. Thus parkinsonism in these two patients was shown to be pathophysiologically different than PD.
