The frequent occurrence of movement disorders such as myoclonus, parkinsonism and dystonia, strongly suggests an involvement of the dopaminergic system in sporadic Creutzfeldt-Jakob disease (sCJD), but this issue has not been specifically addressed yet. Methods –
We report a patient who after a sub-acute focal clinical onset, developed the full clinical picture of probable sCJD. Given the early unilateral right extrapyramidal rigidity, the patient was assessed by single-photon emission computed tomography of the dopamine transporter (DAT) using [123I] FP-CIT. Results –
DAT-scan demonstrated reduced values of presynaptic receptorial trace in the putamen, particularly on the left side, consistent with functional putaminal dopaminergic presynaptic alteration. Conclusions –
The present observation emphasizes the possible role of DAT imaging studies in the investigation of the pathogenesis of movement disorders in CJD.
