Abstract

<abstract abstract-type="main" id="ncn395-abs-0001"> <title>Abstract</title> <p>A 75‐year‐old man presented choreoathetosis dominantly on his left side. Diffusion‐weighted imaging did not show abnormal intensities, whereas <italic>N</italic>‐isopropyl‐<italic>p</italic>‐[¹²³I]iodoamphetamine single‐photon emission computed tomography showed a significant cerebral blood flow increase in the right striatum. The patient was treated with a D2‐blocker agent, and the choreoathetosis gradually decreased. The cerebral blood flow on the right striatum decreased by the following <italic>N</italic>‐isopropyl‐<italic>p</italic>‐[¹²³I]iodoamphetamine single‐photon emission computed tomography. We discussed the mechanism of choreoathetosis from the perspective of the direct and indirect pathways in motor control.</p> </abstract>
