ABSTRACT
REM sleep behavior disorder (RBD) may be idiopathic or associated with various neurodegenerative disorders such as parkinsonian disorders. We report here a patient diagnosed as idiopathic RBD. He had additional clinical features such as anosmia and various autonomic dysfunctions. FP-CIT PET imaging showed reduced bilateral striatal dopamine transporter binding uptake. These findings suggest that patients with idiopathic RBD can have various clinical features seen in parkinsonian disorders beyond sleep complaint.
Keywords: REM sleep behavior disorder | Dopamine transporter | Neurodegenerative diseases.
