Abstract:
We report the case of an adult male patient with Tourette syndrome, self-injurious behavior and depression, refractory to conventional treatment, and whose symptoms remitted after electroconvulsive therapy. Serial Technetium 99m-Ethyl-Cysteinate-Dimer single photon emission tomographies were applied, before, during, and after electroconvulsive therapy. The neural substrates of this treatment process were further analyzed by woxel-wise subtracted single photon emission tomography images.
