title: Brain perfusion abnormalities in a sibship with parkin-linked parkinsonism.
abstract: We demonstrated brain perfusion abnormalities in a sibship with parkin-linked parkinsonism. The sibship consisted of a 64-year-old man and a 62-year-old woman. Both patients had homozygous deletions of exon 4 in the parkin gene. Hypoperfusion in the superior and middle frontal gyrus, and head of caudate nucleus was seen by SPECT with easy Z score imaging system in both patients. These findings may reflect their executive dysfunction demonstrated by neuropsychological tests.
