Study the effectivity of naming therapy on cortical functional changing of neural activities in aphasic patients: Narrative review

Background and Aim : Naming deficits are one of the most sustained and common effects of aphasia. Therapeutic researches confirm the potential values of naming treatments in order to reduce the complex problems of this group. But the main challenge is the stability and generalization in this group. Following treatment cortical changes reveals that it is possible to reactive the lingual areas of these patients. Considering this difference, patterns of changes among the common therapeutic procedures can affect the stability and generalization of treatment results. Therefore in this research, to have a better perception of neural mechanism of lingual substructures, we study the way that neural activities extend in different areas of cortex after semantical and phonological treatments of naming in aphasic patients with left hemisphere ischemia.Methods : In this narrative review article, researches between 2015 and 2019 in Scopus, PubMed and Science direct are studied.Results : This study performs information in different areas; considering the different protocols of studying functional changes of cortex, Left Inferior Frontal Gyrus (LIFG) and different areas of Temporal lobe showed the most effectivity among all studied areas. Furthermore, after naming therapies, increase of neural activity is reported in areas like occipital lobe following presenting the visual stimulant, memory areas and right hemisphere that are indirectly related with lingual processes.Conclusion : It appears that during stages of treatment, depends on language task and type of stimulant, different activation patterns are expected and by selecting the treatments that has the most amount of activation, it is possible to improve the treatment results.
