## Abstract Transcranial sonography (TCS) reveals abnormal spatial extension of substantia nigra (SN) echogenicity in a high proportion of patients with Parkinson's disease (PD). It has been proposed that this abnormality represents a structural trait that is mechanistically distinct from degenerat

## Abstract Transcranial Doppler imaging (TCDI) has been used as a noninvasive diagnostic tool to differentiate Parkinson's disease (PD) from atypical parkinsonism by detecting hyperechogenicity in the substantia nigra (SN). To our knowledge, no TCDI data are available for Asian populations, and TC
