Striatal dopamine release changes in writer’s cramp

Differences in endogenous striatal dopamine release as measured by displacement of [11C]raclopride (RAC ΔBP) in patients with writer’s cramp compared to healthy controls during a right-hand finger tapping task (A) and speech production task (B). RAC ΔBP findings (green) are overlaid with striatal regions found to have reduced D2/D3 receptor availability at rest (yellow) and one cluster shown where these findings overlap in the left putamen (red).
