This is the first report of fMRI in monozygotic twins discordant for AD. FMRI brain activation patterns were examined during visuospatial and verbal working memory tasks. The affected twin had greater parietal involvement bilaterally during both working memory tasks and reduced left dorsolateral prefrontal cortex activity on the visuospatial memory task. Thus, fMRI may identify additional brain regions recruited in patients with AD to perform a given cognitive task.
