To date, only a few cases of improvement of Parkinsonism in depressed patients treated with electroconvulsive therapy (ECT) have been reported. However, no functional imaging data are available to support this finding.
To describe the first observation of increase in dopamine transporter uptake after ECT.
Iodine-123 fluoropropyl-carbomethoxy-3-β-(4-iodophenyltropane) single-photon emission computed tomographic imaging was conducted in a 77-year-old depressed patient displaying symptoms of Parkinson disease (PD) before and after a series of 12 bilateral ECTs.
The patient displayed improvement in PD symptoms and increase in dopamine transporter uptake after ECT.
Our observation suggests that the PD symptoms and decrease in striatal uptake appearing in the context of a depressive episode might warrant further attention, as they might be reversible.
