Background: The Department of Veterans Affairs (VA) has made important contributions to the neuroimaging of aphasia. Through the affiliations of VA researchers with medical faculties, a broad range of questions has been addressed regarding the structural, metabolic, and functional changes that occur in the brain of individuals who develop aphasia. Aims: This report examines some of the work that has been accomplished by VA researchers using CT, MRI, SPECT, and PET imaging approaches. Main Contribution and Conclusions: The reviewed VA research demonstrates that aphasia results from the dynamic relationships that exist between the impact of structural brain damage on brain function in both damaged and non-damaged regions of the brain. The resulting concepts have led to innovative strategies for the neurorehabilitation of aphasia.
