Abstract:
The clinical diagnosis of Parkinson disease (PD) is difficult, as several other neurodegenerative and basal ganglia disorders have similar clinical presentations. Dopamine transporter single-photon emission computed tomography has been proposed as possible diagnostic tool to help differentiate idiopathic PD from essential tremor and other disorders that present with parkinsonian symptoms. In addition, it is valuable in the diagnosis of dementia with Lewy bodies, differentiating it from other causes of dementia such as Alzheimer disease.
