Transcranial Sonography in Parkinsonian Syndromes

Show Summary Details

Preview

Transcranial sonography (TCS) has recently been introduced as an ancillary tool for the diagnostic workup of idiopathic Parkinson’s disease (PD) and related disorders. This approach has found particular use in individuals with early/mild disease manifestations in whom the clinical diagnosis in uncertain. Current research focuses on elucidating the pathophysiological basis of ultrasound changes, and improving the diagnostic accuracy of this versatile and promising imaging tool. The Chapter provides essential information concerning TCS methodology and its limitations, as well as the use of this approach in the differential diagnosis of idiopathic PD, atypical parkinsonian syndromes, and related disorders such as vascular parkinsonism and essential tremor.

Keywords: transcranial sonography; idiopathic PD; atypical parkinsonism; differential diagnosis; vascular parkinsonism; essential tremor
