Z-score maps from a typical patient. An 81-year-old female (with M/C, depression, and anxiety; without dementia, hallucination, or orthostatic hypotension; Movement Disorder Society’s Unified Parkinson’s Disease Rating Scale part III: 49 points in the off-stage and 27 points in the on-stage; levodopa equivalent dose 420 mg/day; Hoehn–Yahr stage 4) showed regional cerebral blood flow increase in the SN, LG, and MG in response to antiparkinsonian drugs. LG, lateral geniculate body; MG, medial geniculate body; SN, substantia nigra.
