Article

This article is a selective review of functional imaging investigations and brain
stimulation studies addressing the neural mechanisms of recovery of
stroke-associated aphasia. The imaging results show that aphasia recovery is
associated with a complex pattern of brain reorganisation, involving both
ipsilateral and contralateral brain regions, which is modulated by lesion size
and site, time post-onset, type of training, and language task. The information
provided by the imaging investigations needs to be integrated with the results of
brain stimulation studies, in order to specify the most effective protocols in
term of modality, locus and timing of stimulation. Further studies, using
multiple imaging and neuromodulation approaches, are required to reach sound
conclusions about the potential usefulness of brain stimulation approaches as an
adjunct to aphasia rehabilitation.
