Down syndrome is characterized by disproportionately severe impairments of speech and language, yet little is known about the neural underpinnings of these deficits. We compared fMRI activation patterns during passive story listening in 9 young adults with Down syndrome and 9 approximately age-matched, typically developing controls. The typically developing group exhibited greater activation than did the Down syndrome group in classical receptive language areas (superior and middle temporal gyri) for forward greater than backward speech; the Down syndrome group exhibited greater activation in cingulate gyrus, superior and inferior parietal lobules, and precuneus for both forward speech greater than rest and backward speech greater than rest. The Down syndrome group showed almost no difference in activation patterns between the language (forward speech) and nonlanguage (backward speech) conditions.
