Cortical Reorganization after Rehabilitation in a Patient with Conduction Aphasia Using High-Density EEG

Conduction aphasia is a language disorder occurred after a left-brain injury. It is characterized<br> by fluent speech production, reading, writing and normal comprehension, while speech repetition is<br> impaired. The aimof this study is to investigate the cortical responses, induced by language activities,<br> in a sub-acute stroke patient affected by conduction aphasia before and after an intensive speech therapy<br> training. The patientwas examined by usingHigh-Density Electroencephalogram(HD-EEG) examination,<br> while was performing language tasks. The patient was evaluated at baseline and after two months<br> after rehabilitative treatment. Our results showed that an intensive rehabilitative process, in sub-acute<br> stroke, could be useful for a good outcome of language deficits. HD-EEG results showed that left<br> parieto-temporol-frontal areas were more activated after 2 months of rehabilitation training compared<br> with baseline. Our results provided evidence that an intensive rehabilitation process could contribute to<br> an inter- and intra-hemispheric reorganization.
