Phonemic fluency improved after inhibitory transcranial magnetic stimulation in a case of chronic aphasia

Twenty-six months after a left hemispheric ischemic stroke an aphasic patient showed a significant improvement in verbal fluency following ten daily sessions of inhibitory 1 Hz repetitive transcranial magnetic stimulation over the right cortex homologous to the Broca's area.No improvement was observed for other linguistic functions or for executive ones. Results confirm the segregation of neural circuitries subtending phonemic and semantic fluency and suggest a selective usefulness of the repetitive transcranial magnetic stimulation treatment.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.
