چکیده مقاله:

Stroke is one of the most common diseases in adults that accompanied by several disabilities. Often, these patients suffering from a speech and language disorderknown as aphasia caused by involvement of language areas in left hemisphere. In recent years, new treatment approaches have emphasized the role of brainstimulation techniques, such as transcranial direct current stimulation (tDCS), as adjuvant strategies to speed up the language recovery process.We reviewed progressin research on tDCS and language functions and on the potential role of tDCS in the treatment of post-stroke aphasia. A growing body of investigations has shown theefficacy of tDCS in facilitating recovery from chronic aphasia, while data regarding subacute aphasia are much more limited and evidence in theacute post-stroke phaseare still lacking. Much remains unknown about how these techniques cause clinical improvement orabout their long-term efficacy, side-effects, and safety.The results ofrecent studies indicate that the application of tDCS could result in particular language recovery, regards to the type of polarity and target area. However, it’s unclear thatwhich stimulation polarity, stimulation of which brain region and which hemisphere is more effective, yet. Currently available data suggest that tDCS over languagerelatedbrain areas can improve language performance in patients with aphasia. Despite the fact that important variables are yet to be determined, tDCS combined with rehabilitation techniques seems a promising therapeutic option for aphasia.
