Cortical reorganization after rehabilitation in a patient with conduction aphasia, by using High Density EEG

Conduction aphasia is a language disorder occurred after a left brain injury. It is characterized by fluent speech production, reading, writing and normal comprehension, while speech repetition is impaired. The aim of this study is to investigate the cortical responses, induced by language activities, in a sub-acute stroke patient affected by conduction aphasia before and after an intensive speech therapy training. The patient was examined by using High Density Electroencephalogram (HD-EEG) examination, while she was performing language tasks. The patient she evaluated at baseline and after two months after rehabilitative treatment. Our results showed that, an intensive rehabilitative process, in sub-acute stroke, could be useful for a good outcome of language deficits. HD-EEG results showed that right fronto-temporal areas were more activated at T1 compared with baseline. Our results provided evidence that an intensive rehabilitation process could contribute to an inter and intra-hemispheric reorganization.
